+Description:
+ Perform SMBIOS calls on supported Dell machines.
+ through the Dell ACPI-WMI interface.
+
+ IOCTL's and buffer formats are defined in:
+ <uapi/linux/wmi.h>
+
+ 1) To perform an SMBIOS call from userspace, you'll need to
+ first determine the minimum size of the calling interface
+ buffer for your machine.
+ Platforms that contain larger buffers can return larger
+ objects from the system firmware.
+ Commonly this size is either 4k or 32k.
+
+ To determine the size of the buffer read() a u64 dword from
+ the WMI character device /dev/wmi/dell-smbios.
+
+ 2) After you've determined the minimum size of the calling
+ interface buffer, you can allocate a structure that represents
+ the structure documented above.
+
+ 3) In the 'length' object store the size of the buffer you
+ determined above and allocated.
+
+ 4) In this buffer object, prepare as necessary for the SMBIOS
+ call you're interested in. Typically SMBIOS buffers have
+ "class", "select", and "input" defined to values that coincide
+ with the data you are interested in.
+ Documenting class/select/input values is outside of the scope
+ of this documentation. Check with the libsmbios project for
+ further documentation on these values.
+
+ 6) Run the call by using ioctl() as described in the header.
+
+ 7) The output will be returned in the buffer object.
+
+ 8) Be sure to free up your allocated object.

+<h3><a name="What Is Tree RCU's Grace Period Memory Ordering Guarantee?">
+What Is Tree RCU's Grace Period Memory Ordering Guarantee?</a></h3>
+
+<p>RCU grace periods provide extremely strong memory-ordering guarantees
+for non-idle non-offline code.
+Any code that happens after the end of a given RCU grace period is guaranteed
+to see the effects of all accesses prior to the beginning of that grace
+period that are within RCU read-side critical sections.
+Similarly, any code that happens before the beginning of a given RCU grace
+period is guaranteed to see the effects of all accesses following the end
+of that grace period that are within RCU read-side critical sections.
+
+<p>This guarantee is particularly pervasive for <tt>synchronize_sched()</tt>,
+for which RCU-sched read-side critical sections include any region
+of code for which preemption is disabled.
+Given that each individual machine instruction can be thought of as
+an extremely small region of preemption-disabled code, one can think of
+<tt>synchronize_sched()</tt> as <tt>smp_mb()</tt> on steroids.
+
+<p>RCU updaters use this guarantee by splitting their updates into
+two phases, one of which is executed before the grace period and
+the other of which is executed after the grace period.
+In the most common use case, phase one removes an element from
+a linked RCU-protected data structure, and phase two frees that element.
+For this to work, any readers that have witnessed state prior to the
+phase-one update (in the common case, removal) must not witness state
+following the phase-two update (in the common case, freeing).
+
+<p>The RCU implementation provides this guarantee using a network
+of lock-based critical sections, memory barriers, and per-CPU
+processing, as is described in the following sections.
+
+<h3><a name="Tree RCU Grace Period Memory Ordering Building Blocks">
+Tree RCU Grace Period Memory Ordering Building Blocks</a></h3>
+
+<p>The workhorse for RCU's grace-period memory ordering is the
+critical section for the <tt>rcu_node</tt> structure's
+<tt>-&gt;lock</tt>.
+These critical sections use helper functions for lock acquisition, including
+<tt>raw_spin_lock_rcu_node()</tt>,
+<tt>raw_spin_lock_irq_rcu_node()</tt>, and
+<tt>raw_spin_lock_irqsave_rcu_node()</tt>.
+Their lock-release counterparts are
+<tt>raw_spin_unlock_rcu_node()</tt>,
+<tt>raw_spin_unlock_irq_rcu_node()</tt>, and
+<tt>raw_spin_unlock_irqrestore_rcu_node()</tt>,
+respectively.
+For completeness, a
+<tt>raw_spin_trylock_rcu_node()</tt>
+is also provided.
+The key point is that the lock-acquisition functions, including
+<tt>raw_spin_trylock_rcu_node()</tt>, all invoke
+<tt>smp_mb__after_unlock_lock()</tt> immediately after successful
+acquisition of the lock.
+
+<p>Therefore, for any given <tt>rcu_node</tt> struction, any access
+happening before one of the above lock-release functions will be seen
+by all CPUs as happening before any access happening after a later
+one of the above lock-acquisition functions.
+Furthermore, any access happening before one of the
+above lock-release function on any given CPU will be seen by all
+CPUs as happening before any access happening after a later one
+of the above lock-acquisition functions executing on that same CPU,
+even if the lock-release and lock-acquisition functions are operating
+on different <tt>rcu_node</tt> structures.
+Tree RCU uses these two ordering guarantees to form an ordering
+network among all CPUs that were in any way involved in the grace
+period, including any CPUs that came online or went offline during
+the grace period in question.
+
+<p>The following litmus test exhibits the ordering effects of these
+lock-acquisition and lock-release functions:
+
+<pre>
+ 1 int x, y, z;
+ 2
+ 3 void task0(void)
+ 4 {
+ 5 raw_spin_lock_rcu_node(rnp);
+ 6 WRITE_ONCE(x, 1);
+ 7 r1 = READ_ONCE(y);
+ 8 raw_spin_unlock_rcu_node(rnp);
+ 9 }
+10
+11 void task1(void)
+12 {
+13 raw_spin_lock_rcu_node(rnp);
+14 WRITE_ONCE(y, 1);
+15 r2 = READ_ONCE(z);
+16 raw_spin_unlock_rcu_node(rnp);
+17 }
+18
+19 void task2(void)
+20 {
+21 WRITE_ONCE(z, 1);
+22 smp_mb();
+23 r3 = READ_ONCE(x);
+24 }
+25
+26 WARN_ON(r1 == 0 &amp;&amp; r2 == 0 &amp;&amp; r3 == 0);
+</pre>
+
+<p>The <tt>WARN_ON()</tt> is evaluated at &ldquo;the end of time&rdquo;,
+after all changes have propagated throughout the system.
+Without the <tt>smp_mb__after_unlock_lock()</tt> provided by the
+acquisition functions, this <tt>WARN_ON()</tt> could trigger, for example
+on PowerPC.
+The <tt>smp_mb__after_unlock_lock()</tt> invocations prevent this
+<tt>WARN_ON()</tt> from triggering.
+
+<p>This approach must be extended to include idle CPUs, which need
+RCU's grace-period memory ordering guarantee to extend to any
+RCU read-side critical sections preceding and following the current
+idle sojourn.
+This case is handled by calls to the strongly ordered
+<tt>atomic_add_return()</tt> read-modify-write atomic operation that
+is invoked within <tt>rcu_dynticks_eqs_enter()</tt> at idle-entry
+time and within <tt>rcu_dynticks_eqs_exit()</tt> at idle-exit time.
+The grace-period kthread invokes <tt>rcu_dynticks_snap()</tt> and
+<tt>rcu_dynticks_in_eqs_since()</tt> (both of which invoke
+an <tt>atomic_add_return()</tt> of zero) to detect idle CPUs.

+<p>Tree RCU's grace--period memory-ordering guarantees rely most

+field, so much so that it is necessary to abbreviate this pattern
+in the diagrams in the next section.

+25 rdtp-&gt;nonlazy_posted_snap = rdtp-&gt;nonlazy_posted;
+26 invoke_rcu_core();
+27 return;
+28 }
+29 if (rdtp-&gt;last_accelerate == jiffies)
+30 return;
+31 rdtp-&gt;last_accelerate = jiffies;

+
+<h4><a name="Callback Registry">Callback Registry</a></h4>
+
+<p>If RCU's grace-period guarantee is to mean anything at all, any
+access that happens before a given invocation of <tt>call_rcu()</tt>
+must also happen before the corresponding grace period.
+The implementation of this portion of RCU's grace period guarantee
+is shown in the following figure:
+
+</p><p><img src="TreeRCU-callback-registry.svg" alt="TreeRCU-callback-registry.svg">
+
+<p>Because <tt>call_rcu()</tt> normally acts only on CPU-local state,
+it provides no ordering guarantees, either for itself or for
+phase one of the update (which again will usually be removal of
+an element from an RCU-protected data structure).
+It simply enqueues the <tt>rcu_head</tt> structure on a per-CPU list,
+which cannot become associated with a grace period until a later
+call to <tt>rcu_accelerate_cbs()</tt>, as shown in the diagram above.
+
+<p>One set of code paths shown on the left invokes
+<tt>rcu_accelerate_cbs()</tt> via
+<tt>note_gp_changes()</tt>, either directly from <tt>call_rcu()</tt> (if
+the current CPU is inundated with queued <tt>rcu_head</tt> structures)
+or more likely from an <tt>RCU_SOFTIRQ</tt> handler.
+Another code path in the middle is taken only in kernels built with
+<tt>CONFIG_RCU_FAST_NO_HZ=y</tt>, which invokes
+<tt>rcu_accelerate_cbs()</tt> via <tt>rcu_prepare_for_idle()</tt>.
+The final code path on the right is taken only in kernels built with
+<tt>CONFIG_HOTPLUG_CPU=y</tt>, which invokes
+<tt>rcu_accelerate_cbs()</tt> via
+<tt>rcu_advance_cbs()</tt>, <tt>rcu_migrate_callbacks</tt>,
+<tt>rcutree_migrate_callbacks()</tt>, and <tt>takedown_cpu()</tt>,
+which in turn is invoked on a surviving CPU after the outgoing
+CPU has been completely offlined.
+
+<p>There are a few other code paths within grace-period processing
+that opportunistically invoke <tt>rcu_accelerate_cbs()</tt>.
+However, either way, all of the CPU's recently queued <tt>rcu_head</tt>
+structures are associated with a future grace-period number under
+the protection of the CPU's lead <tt>rcu_node</tt> structure's
+<tt>-&gt;lock</tt>.
+In all cases, there is full ordering against any prior critical section
+for that same <tt>rcu_node</tt> structure's <tt>-&gt;lock</tt>, and
+also full ordering against any of the current task's or CPU's prior critical
+sections for any <tt>rcu_node</tt> structure's <tt>-&gt;lock</tt>.
+
+<p>The next section will show how this ordering ensures that any
+accesses prior to the <tt>call_rcu()</tt> (particularly including phase
+one of the update)
+happen before the start of the corresponding grace period.

+<h4><a name="Grace-Period Initialization">Grace-Period Initialization</a></h4>
+
+<p>Grace-period initialization is carried out by
+the grace-period kernel thread, which makes several passes over the
+<tt>rcu_node</tt> tree within the <tt>rcu_gp_init()</tt> function.
+This means that showing the full flow of ordering through the
+grace-period computation will require duplicating this tree.
+If you find this confusing, please note that the state of the
+<tt>rcu_node</tt> changes over time, just like Heraclitus's river.
+However, to keep the <tt>rcu_node</tt> river tractable, the
+grace-period kernel thread's traversals are presented in multiple
+parts, starting in this section with the various phases of
+grace-period initialization.
+
+<p>The first ordering-related grace-period initialization action is to
+increment the <tt>rcu_state</tt> structure's <tt>-&gt;gpnum</tt>
+grace-period-number counter, as shown below:
+
+</p><p><img src="TreeRCU-gp-init-1.svg" alt="TreeRCU-gp-init-1.svg" width="75%">
+
+<p>The actual increment is carried out using <tt>smp_store_release()</tt>,
+which helps reject false-positive RCU CPU stall detection.
+Note that only the root <tt>rcu_node</tt> structure is touched.
+
+<p>The first pass through the <tt>rcu_node</tt> tree updates bitmasks
+based on CPUs having come online or gone offline since the start of
+the previous grace period.
+In the common case where the number of online CPUs for this <tt>rcu_node</tt>
+structure has not transitioned to or from zero,
+this pass will scan only the leaf <tt>rcu_node</tt> structures.
+However, if the number of online CPUs for a given leaf <tt>rcu_node</tt>
+structure has transitioned from zero,
+<tt>rcu_init_new_rnp()</tt> will be invoked for the first incoming CPU.
+Similarly, if the number of online CPUs for a given leaf <tt>rcu_node</tt>
+structure has transitioned to zero,
+<tt>rcu_cleanup_dead_rnp()</tt> will be invoked for the last outgoing CPU.
+The diagram below shows the path of ordering if the leftmost
+<tt>rcu_node</tt> structure onlines its first CPU and if the next
+<tt>rcu_node</tt> structure has no online CPUs
+(or, alternatively if the leftmost <tt>rcu_node</tt> structure offlines
+its last CPU and if the next <tt>rcu_node</tt> structure has no online CPUs).
+
+</p><p><img src="TreeRCU-gp-init-2.svg" alt="TreeRCU-gp-init-1.svg" width="75%">
+
+<p>The final <tt>rcu_gp_init()</tt> pass through the <tt>rcu_node</tt>
+tree traverses breadth-first, setting each <tt>rcu_node</tt> structure's
+<tt>-&gt;gpnum</tt> field to the newly incremented value from the
+<tt>rcu_state</tt> structure, as shown in the following diagram.
+
+</p><p><img src="TreeRCU-gp-init-3.svg" alt="TreeRCU-gp-init-1.svg" width="75%">
+
+<p>This change will also cause each CPU's next call to
+<tt>__note_gp_changes()</tt>
+to notice that a new grace period has started, as described in the next
+section.
+But because the grace-period kthread started the grace period at the
+root (with the increment of the <tt>rcu_state</tt> structure's
+<tt>-&gt;gpnum</tt> field) before setting each leaf <tt>rcu_node</tt>
+structure's <tt>-&gt;gpnum</tt> field, each CPU's observation of
+the start of the grace period will happen after the actual start
+of the grace period.

+<p>If the CPU does a context switch, a quiescent state will be

+
+<p>The next time an <tt>RCU_SOFTIRQ</tt> handler executes on

+If <tt>rcu_report_qs_rdp()</tt> verifies that the quiescent state
+really does apply to the current grace period, it invokes
+<tt>rcu_report_rnp()</tt> which traverses up the <tt>rcu_node</tt>
+tree as shown at the bottom of the diagram, clearing bits from
+each <tt>rcu_node</tt> structure's <tt>-&gt;qsmask</tt> field,

+
+<p>Note that traversal passes upwards out of a given <tt>rcu_node</tt>
+structure only if the current CPU is reporting the last quiescent

+A key point is that if a CPU's traversal stops at a given <tt>rcu_node</tt>
+structure, then there will be a later traversal by another CPU
+(or perhaps the same one) that proceeds upwards
+from that point, and the <tt>rcu_node</tt> <tt>-&gt;lock</tt>
+guarantees that the first CPU's quiescent state happens before the

+Applying this line of thought repeatedly shows that all CPUs'
+quiescent states happen before the last CPU traverses through

+<p>Due to energy-efficiency considerations, RCU is forbidden from

+on a per-CPU variable.
+The ordering effects are as shown below:

+This means that any RCU read-side critical sections that precede the
+idle period (the oval near the top of the diagram above) will happen
+before the end of the current grace period.
+Similarly, the beginning of the current grace period will happen before
+any RCU read-side critical sections that follow the

+
+<p>RCU is also forbidden from disturbing offline CPUs, which might well

+as part of the corresponding CPU hotplug operations.
+The ordering effects are shown below:

+</p><p><img src="TreeRCU-hotplug.svg" alt="TreeRCU-hotplug.svg" width="50%">

+they are heavier weight, and thus acquire the CPU's leaf <tt>rcu_node</tt>

+The RCU grace-period kernel thread samples this mask to detect CPUs
+having gone offline since the beginning of this grace period.

+
+<h4><a name="Forcing Quiescent States">Forcing Quiescent States</a></h4>
+
+<p>As noted above, idle and offline CPUs cannot report their own
+quiescent states, and therefore the grace-period kernel thread
+must do the reporting on their behalf.
+This process is called &ldquo;forcing quiescent states&rdquo;, it is

+leaves are traversed.
+However, if there is a newly offlined CPU as illustrated on the left
+or a newly idled CPU as illustrated on the right, the corresponding
+quiescent state will be driven up towards the root.

+<h4><a name="Callback Invocation">Callback Invocation</a></h4>
+
+<p>Once a given CPU's leaf <tt>rcu_node</tt> structure's
+<tt>-&gt;completed</tt> field has been updated, that CPU can begin
+invoking its RCU callbacks that were waiting for this grace period
+to end.
+These callbacks are identified by <tt>rcu_advance_cbs()</tt>,
+which is usually invoked by <tt>__note_gp_changes()</tt>.
+As shown in the diagram below, this invocation can be triggered by
+the scheduling-clock interrupt (<tt>rcu_check_callbacks()</tt> on
+the left) or by idle entry (<tt>rcu_cleanup_after_idle()</tt> on
+the right, but only for kernels build with
+<tt>CONFIG_RCU_FAST_NO_HZ=y</tt>).
+Either way, <tt>RCU_SOFTIRQ</tt> is raised, which results in
+<tt>rcu_do_batch()</tt> invoking the callbacks, which in turn
+allows those callbacks to carry out (either directly or indirectly
+via wakeup) the needed phase-two processing for each update.
+
+</p><p><img src="TreeRCU-callback-invocation.svg" alt="TreeRCU-callback-invocation.svg" width="60%">
+
+<p>Please note that callback invocation can also be prompted by any
+number of corner-case code paths, for example, when a CPU notes that
+it has excessive numbers of callbacks queued.
+In all cases, the CPU acquires its leaf <tt>rcu_node</tt> structure's
+<tt>-&gt;lock</tt> before invoking callbacks, which preserves the
+required ordering against the newly completed grace period.
+
+<p>However, if the callback function communicates to other CPUs,
+for example, doing a wakeup, then it is that function's responsibility
+to maintain ordering.
+For example, if the callback function wakes up a task that runs on
+some other CPU, proper ordering must in place in both the callback
+function and the task being awakened.
+To see why this is important, consider the top half of the
+<a href="#Grace-Period Cleanup">grace-period cleanup</a> diagram.
+The callback might be running on a CPU corresponding to the leftmost
+leaf <tt>rcu_node</tt> structure, and awaken a task that is to run on
+a CPU corresponding to the rightmost leaf <tt>rcu_node</tt> structure,
+and the grace-period kernel thread might not yet have reached the
+rightmost leaf.
+In this case, the grace period's memory ordering might not yet have
+reached that CPU, so again the callback function and the awakened
+task must supply proper ordering.

+Networking over Thunderbolt cable
+---------------------------------
+Thunderbolt technology allows software communication across two hosts
+connected by a Thunderbolt cable.
+
+It is possible to tunnel any kind of traffic over Thunderbolt link but
+currently we only support Apple ThunderboltIP protocol.
+
+If the other host is running Windows or macOS only thing you need to
+do is to connect Thunderbolt cable between the two hosts, the
+``thunderbolt-net`` is loaded automatically. If the other host is also
+Linux you should load ``thunderbolt-net`` manually on one host (it does
+not matter which one)::
+
+ # modprobe thunderbolt-net
+
+This triggers module load on the other host automatically. If the driver
+is built-in to the kernel image, there is no need to do anything.
+
+The driver will create one virtual ethernet interface per Thunderbolt
+port which are named like ``thunderbolt0`` and so on. From this point
+you can either use standard userspace tools like ``ifconfig`` to
+configure the interface or let your GUI to handle it automatically.
+
+Forcing power
+-------------
+Many OEMs include a method that can be used to force the power of a
+thunderbolt controller to an "On" state even if nothing is connected.
+If supported by your machine this will be exposed by the WMI bus with
+a sysfs attribute called "force_power".
+
+For example the intel-wmi-thunderbolt driver exposes this attribute in:
+ /sys/devices/platform/PNP0C14:00/wmi_bus/wmi_bus-PNP0C14:00/86CCFD48-205E-4A77-9C48-2021CBEDE341/force_power
+
+ To force the power to on, write 1 to this attribute file.
+ To disable force power, write 0 to this attribute file.
+
+Note: it's currently not possible to query the force power state of a platform.

+ARM64 ELF hwcaps
+================
+
+This document describes the usage and semantics of the arm64 ELF hwcaps.
+
+
+1. Introduction
+---------------
+
+Some hardware or software features are only available on some CPU
+implementations, and/or with certain kernel configurations, but have no
+architected discovery mechanism available to userspace code at EL0. The
+kernel exposes the presence of these features to userspace through a set
+of flags called hwcaps, exposed in the auxilliary vector.
+
+Userspace software can test for features by acquiring the AT_HWCAP entry
+of the auxilliary vector, and testing whether the relevant flags are
+set, e.g.
+
+bool floating_point_is_present(void)
+{
+ unsigned long hwcaps = getauxval(AT_HWCAP);
+ if (hwcaps & HWCAP_FP)
+ return true;
+
+ return false;
+}
+
+Where software relies on a feature described by a hwcap, it should check
+the relevant hwcap flag to verify that the feature is present before
+attempting to make use of the feature.
+
+Features cannot be probed reliably through other means. When a feature
+is not available, attempting to use it may result in unpredictable
+behaviour, and is not guaranteed to result in any reliable indication
+that the feature is unavailable, such as a SIGILL.
+
+
+2. Interpretation of hwcaps
+---------------------------
+
+The majority of hwcaps are intended to indicate the presence of features
+which are described by architected ID registers inaccessible to
+userspace code at EL0. These hwcaps are defined in terms of ID register
+fields, and should be interpreted with reference to the definition of
+these fields in the ARM Architecture Reference Manual (ARM ARM).
+
+Such hwcaps are described below in the form:
+
+ Functionality implied by idreg.field == val.
+
+Such hwcaps indicate the availability of functionality that the ARM ARM
+defines as being present when idreg.field has value val, but do not
+indicate that idreg.field is precisely equal to val, nor do they
+indicate the absence of functionality implied by other values of
+idreg.field.
+
+Other hwcaps may indicate the presence of features which cannot be
+described by ID registers alone. These may be described without
+reference to ID registers, and may refer to other documentation.
+

+ Scalable Vector Extension support for AArch64 Linux
+ ===================================================
+
+Author: Dave Martin <Dave.Martin@arm.com>
+Date: 4 August 2017
+
+This document outlines briefly the interface provided to userspace by Linux in
+order to support use of the ARM Scalable Vector Extension (SVE).
+
+This is an outline of the most important features and issues only and not
+intended to be exhaustive.
+
+This document does not aim to describe the SVE architecture or programmer's
+model. To aid understanding, a minimal description of relevant programmer's
+model features for SVE is included in Appendix A.
+
+
+1. General
+-----------
+
+* SVE registers Z0..Z31, P0..P15 and FFR and the current vector length VL, are
+ tracked per-thread.
+
+* The presence of SVE is reported to userspace via HWCAP_SVE in the aux vector
+ AT_HWCAP entry. Presence of this flag implies the presence of the SVE
+ instructions and registers, and the Linux-specific system interfaces
+ described in this document. SVE is reported in /proc/cpuinfo as "sve".
+
+* Support for the execution of SVE instructions in userspace can also be
+ detected by reading the CPU ID register ID_AA64PFR0_EL1 using an MRS
+ instruction, and checking that the value of the SVE field is nonzero. [3]
+
+ It does not guarantee the presence of the system interfaces described in the
+ following sections: software that needs to verify that those interfaces are
+ present must check for HWCAP_SVE instead.
+
+* Debuggers should restrict themselves to interacting with the target via the
+ NT_ARM_SVE regset. The recommended way of detecting support for this regset
+ is to connect to a target process first and then attempt a
+ ptrace(PTRACE_GETREGSET, pid, NT_ARM_SVE, &iov).
+
+
+2. Vector length terminology
+-----------------------------
+
+The size of an SVE vector (Z) register is referred to as the "vector length".
+
+To avoid confusion about the units used to express vector length, the kernel
+adopts the following conventions:
+
+* Vector length (VL) = size of a Z-register in bytes
+
+* Vector quadwords (VQ) = size of a Z-register in units of 128 bits
+
+(So, VL = 16 * VQ.)
+
+The VQ convention is used where the underlying granularity is important, such
+as in data structure definitions. In most other situations, the VL convention
+is used. This is consistent with the meaning of the "VL" pseudo-register in
+the SVE instruction set architecture.
+
+
+3. System call behaviour
+-------------------------
+
+* On syscall, V0..V31 are preserved (as without SVE). Thus, bits [127:0] of
+ Z0..Z31 are preserved. All other bits of Z0..Z31, and all of P0..P15 and FFR
+ become unspecified on return from a syscall.
+
+* The SVE registers are not used to pass arguments to or receive results from
+ any syscall.
+
+* In practice the affected registers/bits will be preserved or will be replaced
+ with zeros on return from a syscall, but userspace should not make
+ assumptions about this. The kernel behaviour may vary on a case-by-case
+ basis.
+
+* All other SVE state of a thread, including the currently configured vector
+ length, the state of the PR_SVE_VL_INHERIT flag, and the deferred vector
+ length (if any), is preserved across all syscalls, subject to the specific
+ exceptions for execve() described in section 6.
+
+ In particular, on return from a fork() or clone(), the parent and new child
+ process or thread share identical SVE configuration, matching that of the
+ parent before the call.
+
+
+4. Signal handling
+-------------------
+
+* A new signal frame record sve_context encodes the SVE registers on signal
+ delivery. [1]
+
+* This record is supplementary to fpsimd_context. The FPSR and FPCR registers
+ are only present in fpsimd_context. For convenience, the content of V0..V31
+ is duplicated between sve_context and fpsimd_context.
+
+* The signal frame record for SVE always contains basic metadata, in particular
+ the thread's vector length (in sve_context.vl).
+
+* The SVE registers may or may not be included in the record, depending on
+ whether the registers are live for the thread. The registers are present if
+ and only if:
+ sve_context.head.size >= SVE_SIG_CONTEXT_SIZE(sve_vq_from_vl(sve_context.vl)).
+
+* If the registers are present, the remainder of the record has a vl-dependent
+ size and layout. Macros SVE_SIG_* are defined [1] to facilitate access to
+ the members.
+
+* If the SVE context is too big to fit in sigcontext.__reserved[], then extra
+ space is allocated on the stack, an extra_context record is written in
+ __reserved[] referencing this space. sve_context is then written in the
+ extra space. Refer to [1] for further details about this mechanism.
+
+
+5. Signal return
+-----------------
+
+When returning from a signal handler:
+
+* If there is no sve_context record in the signal frame, or if the record is
+ present but contains no register data as desribed in the previous section,
+ then the SVE registers/bits become non-live and take unspecified values.
+
+* If sve_context is present in the signal frame and contains full register
+ data, the SVE registers become live and are populated with the specified
+ data. However, for backward compatibility reasons, bits [127:0] of Z0..Z31
+ are always restored from the corresponding members of fpsimd_context.vregs[]
+ and not from sve_context. The remaining bits are restored from sve_context.
+
+* Inclusion of fpsimd_context in the signal frame remains mandatory,
+ irrespective of whether sve_context is present or not.
+
+* The vector length cannot be changed via signal return. If sve_context.vl in
+ the signal frame does not match the current vector length, the signal return
+ attempt is treated as illegal, resulting in a forced SIGSEGV.
+
+
+6. prctl extensions
+--------------------
+
+Some new prctl() calls are added to allow programs to manage the SVE vector
+length:
+
+prctl(PR_SVE_SET_VL, unsigned long arg)
+
+ Sets the vector length of the calling thread and related flags, where
+ arg == vl | flags. Other threads of the calling process are unaffected.
+
+ vl is the desired vector length, where sve_vl_valid(vl) must be true.
+
+ flags:
+
+ PR_SVE_SET_VL_INHERIT
+
+ Inherit the current vector length across execve(). Otherwise, the
+ vector length is reset to the system default at execve(). (See
+ Section 9.)
+
+ PR_SVE_SET_VL_ONEXEC
+
+ Defer the requested vector length change until the next execve()
+ performed by this thread.
+
+ The effect is equivalent to implicit exceution of the following
+ call immediately after the next execve() (if any) by the thread:
+
+ prctl(PR_SVE_SET_VL, arg & ~PR_SVE_SET_VL_ONEXEC)
+
+ This allows launching of a new program with a different vector
+ length, while avoiding runtime side effects in the caller.
+
+
+ Without PR_SVE_SET_VL_ONEXEC, the requested change takes effect
+ immediately.
+
+
+ Return value: a nonnegative on success, or a negative value on error:
+ EINVAL: SVE not supported, invalid vector length requested, or
+ invalid flags.
+
+
+ On success:
+
+ * Either the calling thread's vector length or the deferred vector length
+ to be applied at the next execve() by the thread (dependent on whether
+ PR_SVE_SET_VL_ONEXEC is present in arg), is set to the largest value
+ supported by the system that is less than or equal to vl. If vl ==
+ SVE_VL_MAX, the value set will be the largest value supported by the
+ system.
+
+ * Any previously outstanding deferred vector length change in the calling
+ thread is cancelled.
+
+ * The returned value describes the resulting configuration, encoded as for
+ PR_SVE_GET_VL. The vector length reported in this value is the new
+ current vector length for this thread if PR_SVE_SET_VL_ONEXEC was not
+ present in arg; otherwise, the reported vector length is the deferred
+ vector length that will be applied at the next execve() by the calling
+ thread.
+
+ * Changing the vector length causes all of P0..P15, FFR and all bits of
+ Z0..V31 except for Z0 bits [127:0] .. Z31 bits [127:0] to become
+ unspecified. Calling PR_SVE_SET_VL with vl equal to the thread's current
+ vector length, or calling PR_SVE_SET_VL with the PR_SVE_SET_VL_ONEXEC
+ flag, does not constitute a change to the vector length for this purpose.
+
+
+prctl(PR_SVE_GET_VL)
+
+ Gets the vector length of the calling thread.
+
+ The following flag may be OR-ed into the result:
+
+ PR_SVE_SET_VL_INHERIT
+
+ Vector length will be inherited across execve().
+
+ There is no way to determine whether there is an outstanding deferred
+ vector length change (which would only normally be the case between a
+ fork() or vfork() and the corresponding execve() in typical use).
+
+ To extract the vector length from the result, and it with
+ PR_SVE_VL_LEN_MASK.
+
+ Return value: a nonnegative value on success, or a negative value on error:
+ EINVAL: SVE not supported.
+
+
+7. ptrace extensions
+---------------------
+
+* A new regset NT_ARM_SVE is defined for use with PTRACE_GETREGSET and
+ PTRACE_SETREGSET.
+
+ Refer to [2] for definitions.
+
+The regset data starts with struct user_sve_header, containing:
+
+ size
+
+ Size of the complete regset, in bytes.
+ This depends on vl and possibly on other things in the future.
+
+ If a call to PTRACE_GETREGSET requests less data than the value of
+ size, the caller can allocate a larger buffer and retry in order to
+ read the complete regset.
+
+ max_size
+
+ Maximum size in bytes that the regset can grow to for the target
+ thread. The regset won't grow bigger than this even if the target
+ thread changes its vector length etc.
+
+ vl
+
+ Target thread's current vector length, in bytes.
+
+ max_vl
+
+ Maximum possible vector length for the target thread.
+
+ flags
+
+ either
+
+ SVE_PT_REGS_FPSIMD
+
+ SVE registers are not live (GETREGSET) or are to be made
+ non-live (SETREGSET).
+
+ The payload is of type struct user_fpsimd_state, with the same
+ meaning as for NT_PRFPREG, starting at offset
+ SVE_PT_FPSIMD_OFFSET from the start of user_sve_header.
+
+ Extra data might be appended in the future: the size of the
+ payload should be obtained using SVE_PT_FPSIMD_SIZE(vq, flags).
+
+ vq should be obtained using sve_vq_from_vl(vl).
+
+ or
+
+ SVE_PT_REGS_SVE
+
+ SVE registers are live (GETREGSET) or are to be made live
+ (SETREGSET).
+
+ The payload contains the SVE register data, starting at offset
+ SVE_PT_SVE_OFFSET from the start of user_sve_header, and with
+ size SVE_PT_SVE_SIZE(vq, flags);
+
+ ... OR-ed with zero or more of the following flags, which have the same
+ meaning and behaviour as the corresponding PR_SET_VL_* flags:
+
+ SVE_PT_VL_INHERIT
+
+ SVE_PT_VL_ONEXEC (SETREGSET only).
+
+* The effects of changing the vector length and/or flags are equivalent to
+ those documented for PR_SVE_SET_VL.
+
+ The caller must make a further GETREGSET call if it needs to know what VL is
+ actually set by SETREGSET, unless is it known in advance that the requested
+ VL is supported.
+
+* In the SVE_PT_REGS_SVE case, the size and layout of the payload depends on
+ the header fields. The SVE_PT_SVE_*() macros are provided to facilitate
+ access to the members.
+
+* In either case, for SETREGSET it is permissible to omit the payload, in which
+ case only the vector length and flags are changed (along with any
+ consequences of those changes).
+
+* For SETREGSET, if an SVE_PT_REGS_SVE payload is present and the
+ requested VL is not supported, the effect will be the same as if the
+ payload were omitted, except that an EIO error is reported. No
+ attempt is made to translate the payload data to the correct layout
+ for the vector length actually set. The thread's FPSIMD state is
+ preserved, but the remaining bits of the SVE registers become
+ unspecified. It is up to the caller to translate the payload layout
+ for the actual VL and retry.
+
+* The effect of writing a partial, incomplete payload is unspecified.
+
+
+8. ELF coredump extensions
+---------------------------
+
+* A NT_ARM_SVE note will be added to each coredump for each thread of the
+ dumped process. The contents will be equivalent to the data that would have
+ been read if a PTRACE_GETREGSET of NT_ARM_SVE were executed for each thread
+ when the coredump was generated.
+
+
+9. System runtime configuration
+--------------------------------
+
+* To mitigate the ABI impact of expansion of the signal frame, a policy
+ mechanism is provided for administrators, distro maintainers and developers
+ to set the default vector length for userspace processes:
+
+/proc/sys/abi/sve_default_vector_length
+
+ Writing the text representation of an integer to this file sets the system
+ default vector length to the specified value, unless the value is greater
+ than the maximum vector length supported by the system in which case the
+ default vector length is set to that maximum.
+
+ The result can be determined by reopening the file and reading its
+ contents.
+
+ At boot, the default vector length is initially set to 64 or the maximum
+ supported vector length, whichever is smaller. This determines the initial
+ vector length of the init process (PID 1).
+
+ Reading this file returns the current system default vector length.
+
+* At every execve() call, the new vector length of the new process is set to
+ the system default vector length, unless
+
+ * PR_SVE_SET_VL_INHERIT (or equivalently SVE_PT_VL_INHERIT) is set for the
+ calling thread, or
+
+ * a deferred vector length change is pending, established via the
+ PR_SVE_SET_VL_ONEXEC flag (or SVE_PT_VL_ONEXEC).
+
+* Modifying the system default vector length does not affect the vector length
+ of any existing process or thread that does not make an execve() call.
+
+
+Appendix A. SVE programmer's model (informative)
+=================================================
+
+This section provides a minimal description of the additions made by SVE to the
+ARMv8-A programmer's model that are relevant to this document.
+
+Note: This section is for information only and not intended to be complete or
+to replace any architectural specification.
+
+A.1. Registers
+---------------
+
+In A64 state, SVE adds the following:
+
+* 32 8VL-bit vector registers Z0..Z31
+ For each Zn, Zn bits [127:0] alias the ARMv8-A vector register Vn.
+
+ A register write using a Vn register name zeros all bits of the corresponding
+ Zn except for bits [127:0].
+
+* 16 VL-bit predicate registers P0..P15
+
+* 1 VL-bit special-purpose predicate register FFR (the "first-fault register")
+
+* a VL "pseudo-register" that determines the size of each vector register
+
+ The SVE instruction set architecture provides no way to write VL directly.
+ Instead, it can be modified only by EL1 and above, by writing appropriate
+ system registers.
+
+* The value of VL can be configured at runtime by EL1 and above:
+ 16 <= VL <= VLmax, where VL must be a multiple of 16.
+
+* The maximum vector length is determined by the hardware:
+ 16 <= VLmax <= 256.
+
+ (The SVE architecture specifies 256, but permits future architecture
+ revisions to raise this limit.)
+
+* FPSR and FPCR are retained from ARMv8-A, and interact with SVE floating-point
+ operations in a similar way to the way in which they interact with ARMv8
+ floating-point operations.

+ This only applies to bits [63:0] of Z-/V-registers.
+ FPCR contains callee-save and caller-save bits. See [4] for details.
+
+
+A.2. Procedure call standard
+-----------------------------
+
+The ARMv8-A base procedure call standard is extended as follows with respect to
+the additional SVE register state:
+
+* All SVE register bits that are not shared with FP/SIMD are caller-save.
+
+* Z8 bits [63:0] .. Z15 bits [63:0] are callee-save.
+
+ This follows from the way these bits are mapped to V8..V15, which are caller-
+ save in the base procedure call standard.

+===============================================
+
+Note: This section is for information only and not intended to be complete or

+
+Refer to [4] for for more information.
+
+ARMv8-A defines the following floating-point / SIMD register state:

+BPF extensibility and applicability to networking, tracing, security
+in the linux kernel and several user space implementations of BPF
+virtual machine led to a number of misunderstanding on what BPF actually is.
+This short QA is an attempt to address that and outline a direction
+of where BPF is heading long term.
+
+Q: Is BPF a generic instruction set similar to x64 and arm64?
+A: NO.
+
+Q: Is BPF a generic virtual machine ?
+A: NO.
+
+BPF is generic instruction set _with_ C calling convention.
+
+Q: Why C calling convention was chosen?
+A: Because BPF programs are designed to run in the linux kernel
+ which is written in C, hence BPF defines instruction set compatible
+ with two most used architectures x64 and arm64 (and takes into
+ consideration important quirks of other architectures) and
+ defines calling convention that is compatible with C calling
+ convention of the linux kernel on those architectures.
+
+Q: can multiple return values be supported in the future?
+A: NO. BPF allows only register R0 to be used as return value.
+
+Q: can more than 5 function arguments be supported in the future?
+A: NO. BPF calling convention only allows registers R1-R5 to be used
+ as arguments. BPF is not a standalone instruction set.
+ (unlike x64 ISA that allows msft, cdecl and other conventions)
+
+Q: can BPF programs access instruction pointer or return address?
+A: NO.
+
+Q: can BPF programs access stack pointer ?
+A: NO. Only frame pointer (register R10) is accessible.
+ From compiler point of view it's necessary to have stack pointer.
+ For example LLVM defines register R11 as stack pointer in its
+ BPF backend, but it makes sure that generated code never uses it.
+
+Q: Does C-calling convention diminishes possible use cases?
+A: YES. BPF design forces addition of major functionality in the form
+ of kernel helper functions and kernel objects like BPF maps with
+ seamless interoperability between them. It lets kernel call into
+ BPF programs and programs call kernel helpers with zero overhead.
+ As all of them were native C code. That is particularly the case
+ for JITed BPF programs that are indistinguishable from
+ native kernel C code.
+
+Q: Does it mean that 'innovative' extensions to BPF code are disallowed?
+A: Soft yes. At least for now until BPF core has support for
+ bpf-to-bpf calls, indirect calls, loops, global variables,
+ jump tables, read only sections and all other normal constructs
+ that C code can produce.
+
+Q: Can loops be supported in a safe way?
+A: It's not clear yet. BPF developers are trying to find a way to
+ support bounded loops where the verifier can guarantee that
+ the program terminates in less than 4096 instructions.
+
+Q: How come LD_ABS and LD_IND instruction are present in BPF whereas
+ C code cannot express them and has to use builtin intrinsics?
+A: This is artifact of compatibility with classic BPF. Modern
+ networking code in BPF performs better without them.
+ See 'direct packet access'.
+
+Q: It seems not all BPF instructions are one-to-one to native CPU.
+ For example why BPF_JNE and other compare and jumps are not cpu-like?
+A: This was necessary to avoid introducing flags into ISA which are
+ impossible to make generic and efficient across CPU architectures.
+
+Q: why BPF_DIV instruction doesn't map to x64 div?
+A: Because if we picked one-to-one relationship to x64 it would have made
+ it more complicated to support on arm64 and other archs. Also it
+ needs div-by-zero runtime check.
+
+Q: why there is no BPF_SDIV for signed divide operation?
+A: Because it would be rarely used. llvm errors in such case and
+ prints a suggestion to use unsigned divide instead
+
+Q: Why BPF has implicit prologue and epilogue?
+A: Because architectures like sparc have register windows and in general
+ there are enough subtle differences between architectures, so naive
+ store return address into stack won't work. Another reason is BPF has
+ to be safe from division by zero (and legacy exception path
+ of LD_ABS insn). Those instructions need to invoke epilogue and
+ return implicitly.
+
+Q: Why BPF_JLT and BPF_JLE instructions were not introduced in the beginning?
+A: Because classic BPF didn't have them and BPF authors felt that compiler
+ workaround would be acceptable. Turned out that programs lose performance
+ due to lack of these compare instructions and they were added.
+ These two instructions is a perfect example what kind of new BPF
+ instructions are acceptable and can be added in the future.
+ These two already had equivalent instructions in native CPUs.
+ New instructions that don't have one-to-one mapping to HW instructions
+ will not be accepted.
+
+Q: BPF 32-bit subregisters have a requirement to zero upper 32-bits of BPF
+ registers which makes BPF inefficient virtual machine for 32-bit
+ CPU architectures and 32-bit HW accelerators. Can true 32-bit registers
+ be added to BPF in the future?
+A: NO. The first thing to improve performance on 32-bit archs is to teach
+ LLVM to generate code that uses 32-bit subregisters. Then second step
+ is to teach verifier to mark operations where zero-ing upper bits
+ is unnecessary. Then JITs can take advantage of those markings and
+ drastically reduce size of generated code and improve performance.
+
+Q: Does BPF have a stable ABI?
+A: YES. BPF instructions, arguments to BPF programs, set of helper
+ functions and their arguments, recognized return codes are all part
+ of ABI. However when tracing programs are using bpf_probe_read() helper
+ to walk kernel internal datastructures and compile with kernel
+ internal headers these accesses can and will break with newer
+ kernels. The union bpf_attr -> kern_version is checked at load time
+ to prevent accidentally loading kprobe-based bpf programs written
+ for a different kernel. Networking programs don't do kern_version check.
+
+Q: How much stack space a BPF program uses?
+A: Currently all program types are limited to 512 bytes of stack
+ space, but the verifier computes the actual amount of stack used
+ and both interpreter and most JITed code consume necessary amount.
+
+Q: Can BPF be offloaded to HW?
+A: YES. BPF HW offload is supported by NFP driver.
+
+Q: Does classic BPF interpreter still exist?
+A: NO. Classic BPF programs are converted into extend BPF instructions.
+
+Q: Can BPF call arbitrary kernel functions?
+A: NO. BPF programs can only call a set of helper functions which
+ is defined for every program type.
+
+Q: Can BPF overwrite arbitrary kernel memory?
+A: NO. Tracing bpf programs can _read_ arbitrary memory with bpf_probe_read()
+ and bpf_probe_read_str() helpers. Networking programs cannot read
+ arbitrary memory, since they don't have access to these helpers.
+ Programs can never read or write arbitrary memory directly.
+
+Q: Can BPF overwrite arbitrary user memory?
+A: Sort-of. Tracing BPF programs can overwrite the user memory
+ of the current task with bpf_probe_write_user(). Every time such
+ program is loaded the kernel will print warning message, so
+ this helper is only useful for experiments and prototypes.
+ Tracing BPF programs are root only.
+
+Q: When bpf_trace_printk() helper is used the kernel prints nasty
+ warning message. Why is that?
+A: This is done to nudge program authors into better interfaces when
+ programs need to pass data to user space. Like bpf_perf_event_output()
+ can be used to efficiently stream data via perf ring buffer.
+ BPF maps can be used for asynchronous data sharing between kernel
+ and user space. bpf_trace_printk() should only be used for debugging.
+
+Q: Can BPF functionality such as new program or map types, new
+ helpers, etc be added out of kernel module code?
+A: NO.

-Getting started with kmemcheck
-==============================
-
-Vegard Nossum <vegardno@ifi.uio.no>
-
-
-Introduction
-------------
-
-kmemcheck is a debugging feature for the Linux Kernel. More specifically, it
-is a dynamic checker that detects and warns about some uses of uninitialized
-memory.
-
-Userspace programmers might be familiar with Valgrind's memcheck. The main
-difference between memcheck and kmemcheck is that memcheck works for userspace
-programs only, and kmemcheck works for the kernel only. The implementations
-are of course vastly different. Because of this, kmemcheck is not as accurate
-as memcheck, but it turns out to be good enough in practice to discover real
-programmer errors that the compiler is not able to find through static
-analysis.
-
-Enabling kmemcheck on a kernel will probably slow it down to the extent that
-the machine will not be usable for normal workloads such as e.g. an
-interactive desktop. kmemcheck will also cause the kernel to use about twice
-as much memory as normal. For this reason, kmemcheck is strictly a debugging
-feature.
-
-
-Downloading
------------
-
-As of version 2.6.31-rc1, kmemcheck is included in the mainline kernel.
-
-
-Configuring and compiling
--------------------------
-
-kmemcheck only works for the x86 (both 32- and 64-bit) platform. A number of
-configuration variables must have specific settings in order for the kmemcheck
-menu to even appear in "menuconfig". These are:
-
-- ``CONFIG_CC_OPTIMIZE_FOR_SIZE=n``
- This option is located under "General setup" / "Optimize for size".
-
- Without this, gcc will use certain optimizations that usually lead to
- false positive warnings from kmemcheck. An example of this is a 16-bit
- field in a struct, where gcc may load 32 bits, then discard the upper
- 16 bits. kmemcheck sees only the 32-bit load, and may trigger a
- warning for the upper 16 bits (if they're uninitialized).
-
-- ``CONFIG_SLAB=y`` or ``CONFIG_SLUB=y``
- This option is located under "General setup" / "Choose SLAB
- allocator".
-
-- ``CONFIG_FUNCTION_TRACER=n``
- This option is located under "Kernel hacking" / "Tracers" / "Kernel
- Function Tracer"
-
- When function tracing is compiled in, gcc emits a call to another
- function at the beginning of every function. This means that when the
- page fault handler is called, the ftrace framework will be called
- before kmemcheck has had a chance to handle the fault. If ftrace then
- modifies memory that was tracked by kmemcheck, the result is an
- endless recursive page fault.
-
-- ``CONFIG_DEBUG_PAGEALLOC=n``
- This option is located under "Kernel hacking" / "Memory Debugging"
- / "Debug page memory allocations".
-
-In addition, I highly recommend turning on ``CONFIG_DEBUG_INFO=y``. This is also
-located under "Kernel hacking". With this, you will be able to get line number
-information from the kmemcheck warnings, which is extremely valuable in
-debugging a problem. This option is not mandatory, however, because it slows
-down the compilation process and produces a much bigger kernel image.
-
-Now the kmemcheck menu should be visible (under "Kernel hacking" / "Memory
-Debugging" / "kmemcheck: trap use of uninitialized memory"). Here follows
-a description of the kmemcheck configuration variables:
-
-- ``CONFIG_KMEMCHECK``
- This must be enabled in order to use kmemcheck at all...
-
-- ``CONFIG_KMEMCHECK_``[``DISABLED`` | ``ENABLED`` | ``ONESHOT``]``_BY_DEFAULT``
- This option controls the status of kmemcheck at boot-time. "Enabled"
- will enable kmemcheck right from the start, "disabled" will boot the
- kernel as normal (but with the kmemcheck code compiled in, so it can
- be enabled at run-time after the kernel has booted), and "one-shot" is
- a special mode which will turn kmemcheck off automatically after
- detecting the first use of uninitialized memory.
-
- If you are using kmemcheck to actively debug a problem, then you
- probably want to choose "enabled" here.
-
- The one-shot mode is mostly useful in automated test setups because it
- can prevent floods of warnings and increase the chances of the machine
- surviving in case something is really wrong. In other cases, the one-
- shot mode could actually be counter-productive because it would turn
- itself off at the very first error -- in the case of a false positive
- too -- and this would come in the way of debugging the specific
- problem you were interested in.
-
- If you would like to use your kernel as normal, but with a chance to
- enable kmemcheck in case of some problem, it might be a good idea to
- choose "disabled" here. When kmemcheck is disabled, most of the run-
- time overhead is not incurred, and the kernel will be almost as fast
- as normal.
-
-- ``CONFIG_KMEMCHECK_QUEUE_SIZE``
- Select the maximum number of error reports to store in an internal
- (fixed-size) buffer. Since errors can occur virtually anywhere and in
- any context, we need a temporary storage area which is guaranteed not
- to generate any other page faults when accessed. The queue will be
- emptied as soon as a tasklet may be scheduled. If the queue is full,
- new error reports will be lost.
-
- The default value of 64 is probably fine. If some code produces more
- than 64 errors within an irqs-off section, then the code is likely to
- produce many, many more, too, and these additional reports seldom give
- any more information (the first report is usually the most valuable
- anyway).
-
- This number might have to be adjusted if you are not using serial
- console or similar to capture the kernel log. If you are using the
- "dmesg" command to save the log, then getting a lot of kmemcheck
- warnings might overflow the kernel log itself, and the earlier reports
- will get lost in that way instead. Try setting this to 10 or so on
- such a setup.
-
-- ``CONFIG_KMEMCHECK_SHADOW_COPY_SHIFT``
- Select the number of shadow bytes to save along with each entry of the
- error-report queue. These bytes indicate what parts of an allocation
- are initialized, uninitialized, etc. and will be displayed when an
- error is detected to help the debugging of a particular problem.
-
- The number entered here is actually the logarithm of the number of
- bytes that will be saved. So if you pick for example 5 here, kmemcheck
- will save 2^5 = 32 bytes.
-
- The default value should be fine for debugging most problems. It also
- fits nicely within 80 columns.
-
-- ``CONFIG_KMEMCHECK_PARTIAL_OK``
- This option (when enabled) works around certain GCC optimizations that
- produce 32-bit reads from 16-bit variables where the upper 16 bits are
- thrown away afterwards.
-
- The default value (enabled) is recommended. This may of course hide
- some real errors, but disabling it would probably produce a lot of
- false positives.
-
-- ``CONFIG_KMEMCHECK_BITOPS_OK``
- This option silences warnings that would be generated for bit-field
- accesses where not all the bits are initialized at the same time. This
- may also hide some real bugs.
-
- This option is probably obsolete, or it should be replaced with
- the kmemcheck-/bitfield-annotations for the code in question. The
- default value is therefore fine.
-
-Now compile the kernel as usual.
-
-
-How to use
-----------
-
-Booting
-~~~~~~~
-
-First some information about the command-line options. There is only one
-option specific to kmemcheck, and this is called "kmemcheck". It can be used
-to override the default mode as chosen by the ``CONFIG_KMEMCHECK_*_BY_DEFAULT``
-option. Its possible settings are:
-
-- ``kmemcheck=0`` (disabled)
-- ``kmemcheck=1`` (enabled)
-- ``kmemcheck=2`` (one-shot mode)
-
-If SLUB debugging has been enabled in the kernel, it may take precedence over
-kmemcheck in such a way that the slab caches which are under SLUB debugging
-will not be tracked by kmemcheck. In order to ensure that this doesn't happen
-(even though it shouldn't by default), use SLUB's boot option ``slub_debug``,
-like this: ``slub_debug=-``
-
-In fact, this option may also be used for fine-grained control over SLUB vs.
-kmemcheck. For example, if the command line includes
-``kmemcheck=1 slub_debug=,dentry``, then SLUB debugging will be used only
-for the "dentry" slab cache, and with kmemcheck tracking all the other
-caches. This is advanced usage, however, and is not generally recommended.
-
-
-Run-time enable/disable
-~~~~~~~~~~~~~~~~~~~~~~~
-
-When the kernel has booted, it is possible to enable or disable kmemcheck at
-run-time. WARNING: This feature is still experimental and may cause false
-positive warnings to appear. Therefore, try not to use this. If you find that
-it doesn't work properly (e.g. you see an unreasonable amount of warnings), I
-will be happy to take bug reports.
-
-Use the file ``/proc/sys/kernel/kmemcheck`` for this purpose, e.g.::
-
- $ echo 0 > /proc/sys/kernel/kmemcheck # disables kmemcheck
-
-The numbers are the same as for the ``kmemcheck=`` command-line option.
-
-

-If your kernel was compiled with ``CONFIG_DEBUG_INFO=y``, then all we have to do
-is give this address to the addr2line program, like this::
-
- $ addr2line -e vmlinux -i ffffffff8104ede8
- arch/x86/include/asm/string_64.h:12
- include/asm-generic/siginfo.h:287
- kernel/signal.c:380
- kernel/signal.c:410
-
-The "``-e vmlinux``" tells addr2line which file to look in. **IMPORTANT:**
-This must be the vmlinux of the kernel that produced the warning in the
-first place! If not, the line number information will almost certainly be
-wrong.
-
-The "``-i``" tells addr2line to also print the line numbers of inlined
-functions. In this case, the flag was very important, because otherwise,
-it would only have printed the first line, which is just a call to
-``memcpy()``, which could be called from a thousand places in the kernel, and
-is therefore not very useful. These inlined functions would not show up in
-the stack trace above, simply because the kernel doesn't load the extra
-debugging information. This technique can of course be used with ordinary
-kernel oopses as well.
-
-In this case, it's the caller of ``memcpy()`` that is interesting, and it can be
-found in ``include/asm-generic/siginfo.h``, line 287::
-
- 281 static inline void copy_siginfo(struct siginfo *to, struct siginfo *from)
- 282 {
- 283 if (from->si_code < 0)
- 284 memcpy(to, from, sizeof(*to));
- 285 else
- 286 /* _sigchld is currently the largest know union member */
- 287 memcpy(to, from, __ARCH_SI_PREAMBLE_SIZE + sizeof(from->_sifields._sigchld));
- 288 }
-
-Since this was a read (kmemcheck usually warns about reads only, though it can
-warn about writes to unallocated or freed memory as well), it was probably the
-"from" argument which contained some uninitialized bytes. Following the chain
-of calls, we move upwards to see where "from" was allocated or initialized,
-``kernel/signal.c``, line 380::
-
- 359 static void collect_signal(int sig, struct sigpending *list, siginfo_t *info)
- 360 {
- ...
- 367 list_for_each_entry(q, &list->list, list) {
- 368 if (q->info.si_signo == sig) {
- 369 if (first)
- 370 goto still_pending;
- 371 first = q;
- ...
- 377 if (first) {
- 378 still_pending:
- 379 list_del_init(&first->list);
- 380 copy_siginfo(info, &first->info);
- 381 __sigqueue_free(first);
- ...
- 392 }
- 393 }
-
-Here, it is ``&first->info`` that is being passed on to ``copy_siginfo()``. The
-variable ``first`` was found on a list -- passed in as the second argument to
-``collect_signal()``. We continue our journey through the stack, to figure out
-where the item on "list" was allocated or initialized. We move to line 410::
-
- 395 static int __dequeue_signal(struct sigpending *pending, sigset_t *mask,
- 396 siginfo_t *info)
- 397 {
- ...
- 410 collect_signal(sig, pending, info);
- ...
- 414 }
-
-Now we need to follow the ``pending`` pointer, since that is being passed on to
-``collect_signal()`` as ``list``. At this point, we've run out of lines from the
-"addr2line" output. Not to worry, we just paste the next addresses from the
-kmemcheck stack dump, i.e.::
-
- [<ffffffff8104f04e>] dequeue_signal+0x8e/0x170
- [<ffffffff81050bd8>] get_signal_to_deliver+0x98/0x390
- [<ffffffff8100b87d>] do_notify_resume+0xad/0x7d0
- [<ffffffff8100c7b5>] int_signal+0x12/0x17
-
- $ addr2line -e vmlinux -i ffffffff8104f04e ffffffff81050bd8 \
- ffffffff8100b87d ffffffff8100c7b5
- kernel/signal.c:446
- kernel/signal.c:1806
- arch/x86/kernel/signal.c:805
- arch/x86/kernel/signal.c:871
- arch/x86/kernel/entry_64.S:694
-
-Remember that since these addresses were found on the stack and not as the
-RIP value, they actually point to the _next_ instruction (they are return
-addresses). This becomes obvious when we look at the code for line 446::
-
- 422 int dequeue_signal(struct task_struct *tsk, sigset_t *mask, siginfo_t *info)
- 423 {
- ...
- 431 signr = __dequeue_signal(&tsk->signal->shared_pending,
- 432 mask, info);
- 433 /*
- 434 * itimer signal ?
- 435 *
- 436 * itimers are process shared and we restart periodic
- 437 * itimers in the signal delivery path to prevent DoS
- 438 * attacks in the high resolution timer case. This is
- 439 * compliant with the old way of self restarting
- 440 * itimers, as the SIGALRM is a legacy signal and only
- 441 * queued once. Changing the restart behaviour to
- 442 * restart the timer in the signal dequeue path is
- 443 * reducing the timer noise on heavy loaded !highres
- 444 * systems too.
- 445 */
- 446 if (unlikely(signr == SIGALRM)) {
- ...
- 489 }
-
-So instead of looking at 446, we should be looking at 431, which is the line
-that executes just before 446. Here we see that what we are looking for is
-``&tsk->signal->shared_pending``.
-
-Our next task is now to figure out which function that puts items on this
-``shared_pending`` list. A crude, but efficient tool, is ``git grep``::
-
- $ git grep -n 'shared_pending' kernel/
- ...
- kernel/signal.c:828: pending = group ? &t->signal->shared_pending : &t->pending;
- kernel/signal.c:1339: pending = group ? &t->signal->shared_pending : &t->pending;
- ...
-
-There were more results, but none of them were related to list operations,
-and these were the only assignments. We inspect the line numbers more closely
-and find that this is indeed where items are being added to the list::
-
- 816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
- 817 int group)
- 818 {
- ...
- 828 pending = group ? &t->signal->shared_pending : &t->pending;
- ...
- 851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
- 852 (is_si_special(info) ||
- 853 info->si_code >= 0)));
- 854 if (q) {
- 855 list_add_tail(&q->list, &pending->list);
- ...
- 890 }
-
-and::
-
- 1309 int send_sigqueue(struct sigqueue *q, struct task_struct *t, int group)
- 1310 {
- ....
- 1339 pending = group ? &t->signal->shared_pending : &t->pending;
- 1340 list_add_tail(&q->list, &pending->list);
- ....
- 1347 }
-
-In the first case, the list element we are looking for, ``q``, is being
-returned from the function ``__sigqueue_alloc()``, which looks like an
-allocation function. Let's take a look at it::
-
- 187 static struct sigqueue *__sigqueue_alloc(struct task_struct *t, gfp_t flags,
- 188 int override_rlimit)
- 189 {
- 190 struct sigqueue *q = NULL;
- 191 struct user_struct *user;
- 192
- 193 /*
- 194 * We won't get problems with the target's UID changing under us
- 195 * because changing it requires RCU be used, and if t != current, the
- 196 * caller must be holding the RCU readlock (by way of a spinlock) and
- 197 * we use RCU protection here
- 198 */
- 199 user = get_uid(__task_cred(t)->user);
- 200 atomic_inc(&user->sigpending);
- 201 if (override_rlimit ||
- 202 atomic_read(&user->sigpending) <=
- 203 t->signal->rlim[RLIMIT_SIGPENDING].rlim_cur)
- 204 q = kmem_cache_alloc(sigqueue_cachep, flags);
- 205 if (unlikely(q == NULL)) {
- 206 atomic_dec(&user->sigpending);
- 207 free_uid(user);
- 208 } else {
- 209 INIT_LIST_HEAD(&q->list);
- 210 q->flags = 0;
- 211 q->user = user;
- 212 }
- 213
- 214 return q;
- 215 }
-
-We see that this function initializes ``q->list``, ``q->flags``, and
-``q->user``. It seems that now is the time to look at the definition of
-``struct sigqueue``, e.g.::
-
- 14 struct sigqueue {
- 15 struct list_head list;
- 16 int flags;
- 17 siginfo_t info;
- 18 struct user_struct *user;
- 19 };
-
-And, you might remember, it was a ``memcpy()`` on ``&first->info`` that
-caused the warning, so this makes perfect sense. It also seems reasonable
-to assume that it is the caller of ``__sigqueue_alloc()`` that has the
-responsibility of filling out (initializing) this member.
-
-But just which fields of the struct were uninitialized? Let's look at
-kmemcheck's report again::
-
- WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88003e4a2024)
- 80000000000000000000000000000000000000000088ffff0000000000000000
- i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
- ^
-
-These first two lines are the memory dump of the memory object itself, and
-the shadow bytemap, respectively. The memory object itself is in this case
-``&first->info``. Just beware that the start of this dump is NOT the start
-of the object itself! The position of the caret (^) corresponds with the
-address of the read (ffff88003e4a2024).
-
-The shadow bytemap dump legend is as follows:
-
-- i: initialized
-- u: uninitialized
-- a: unallocated (memory has been allocated by the slab layer, but has not
- yet been handed off to anybody)
-- f: freed (memory has been allocated by the slab layer, but has been freed
- by the previous owner)
-
-In order to figure out where (relative to the start of the object) the
-uninitialized memory was located, we have to look at the disassembly. For
-that, we'll need the RIP address again::
-
- RIP: 0010:[<ffffffff8104ede8>] [<ffffffff8104ede8>] __dequeue_signal+0xc8/0x190
-
- $ objdump -d --no-show-raw-insn vmlinux | grep -C 8 ffffffff8104ede8:
- ffffffff8104edc8: mov %r8,0x8(%r8)
- ffffffff8104edcc: test %r10d,%r10d
- ffffffff8104edcf: js ffffffff8104ee88 <__dequeue_signal+0x168>
- ffffffff8104edd5: mov %rax,%rdx
- ffffffff8104edd8: mov $0xc,%ecx
- ffffffff8104eddd: mov %r13,%rdi
- ffffffff8104ede0: mov $0x30,%eax
- ffffffff8104ede5: mov %rdx,%rsi
- ffffffff8104ede8: rep movsl %ds:(%rsi),%es:(%rdi)
- ffffffff8104edea: test $0x2,%al
- ffffffff8104edec: je ffffffff8104edf0 <__dequeue_signal+0xd0>
- ffffffff8104edee: movsw %ds:(%rsi),%es:(%rdi)
- ffffffff8104edf0: test $0x1,%al
- ffffffff8104edf2: je ffffffff8104edf5 <__dequeue_signal+0xd5>
- ffffffff8104edf4: movsb %ds:(%rsi),%es:(%rdi)
- ffffffff8104edf5: mov %r8,%rdi
- ffffffff8104edf8: callq ffffffff8104de60 <__sigqueue_free>
-
-As expected, it's the "``rep movsl``" instruction from the ``memcpy()``
-that causes the warning. We know about ``REP MOVSL`` that it uses the register
-``RCX`` to count the number of remaining iterations. By taking a look at the
-register dump again (from the kmemcheck report), we can figure out how many
-bytes were left to copy::
-
- RAX: 0000000000000030 RBX: ffff88003d4ea968 RCX: 0000000000000009
-
-By looking at the disassembly, we also see that ``%ecx`` is being loaded
-with the value ``$0xc`` just before (ffffffff8104edd8), so we are very
-lucky. Keep in mind that this is the number of iterations, not bytes. And
-since this is a "long" operation, we need to multiply by 4 to get the
-number of bytes. So this means that the uninitialized value was encountered
-at 4 * (0xc - 0x9) = 12 bytes from the start of the object.
-
-We can now try to figure out which field of the "``struct siginfo``" that
-was not initialized. This is the beginning of the struct::
-
- 40 typedef struct siginfo {
- 41 int si_signo;
- 42 int si_errno;
- 43 int si_code;
- 44
- 45 union {
- ..
- 92 } _sifields;
- 93 } siginfo_t;
-
-On 64-bit, the int is 4 bytes long, so it must the union member that has
-not been initialized. We can verify this using gdb::
-
- $ gdb vmlinux
- ...
- (gdb) p &((struct siginfo *) 0)->_sifields
- $1 = (union {...} *) 0x10
-
-Actually, it seems that the union member is located at offset 0x10 -- which
-means that gcc has inserted 4 bytes of padding between the members ``si_code``
-and ``_sifields``. We can now get a fuller picture of the memory dump::
-
- _----------------------------=> si_code
- / _--------------------=> (padding)
- | / _------------=> _sifields(._kill._pid)
- | | / _----=> _sifields(._kill._uid)
- | | | /
- -------|-------|-------|-------|
- 80000000000000000000000000000000000000000088ffff0000000000000000
- i i i i u u u u i i i i i i i i u u u u u u u u u u u u u u u u
-
-This allows us to realize another important fact: ``si_code`` contains the
-value 0x80. Remember that x86 is little endian, so the first 4 bytes
-"80000000" are really the number 0x00000080. With a bit of research, we
-find that this is actually the constant ``SI_KERNEL`` defined in
-``include/asm-generic/siginfo.h``::
-
- 144 #define SI_KERNEL 0x80 /* sent by the kernel from somewhere */
-
-This macro is used in exactly one place in the x86 kernel: In ``send_signal()``
-in ``kernel/signal.c``::
-
- 816 static int send_signal(int sig, struct siginfo *info, struct task_struct *t,
- 817 int group)
- 818 {
- ...
- 828 pending = group ? &t->signal->shared_pending : &t->pending;
- ...
- 851 q = __sigqueue_alloc(t, GFP_ATOMIC, (sig < SIGRTMIN &&
- 852 (is_si_special(info) ||
- 853 info->si_code >= 0)));
- 854 if (q) {
- 855 list_add_tail(&q->list, &pending->list);
- 856 switch ((unsigned long) info) {
- ...
- 865 case (unsigned long) SEND_SIG_PRIV:
- 866 q->info.si_signo = sig;
- 867 q->info.si_errno = 0;
- 868 q->info.si_code = SI_KERNEL;
- 869 q->info.si_pid = 0;
- 870 q->info.si_uid = 0;
- 871 break;
- ...
- 890 }
-
-Not only does this match with the ``.si_code`` member, it also matches the place
-we found earlier when looking for where siginfo_t objects are enqueued on the
-``shared_pending`` list.
-
-So to sum up: It seems that it is the padding introduced by the compiler
-between two struct fields that is uninitialized, and this gets reported when
-we do a ``memcpy()`` on the struct. This means that we have identified a false
-positive warning.
-
-Normally, kmemcheck will not report uninitialized accesses in ``memcpy()`` calls
-when both the source and destination addresses are tracked. (Instead, we copy
-the shadow bytemap as well). In this case, the destination address clearly
-was not tracked. We can dig a little deeper into the stack trace from above::
-
- arch/x86/kernel/signal.c:805
- arch/x86/kernel/signal.c:871
- arch/x86/kernel/entry_64.S:694
-
-And we clearly see that the destination siginfo object is located on the
-stack::
-
- 782 static void do_signal(struct pt_regs *regs)
- 783 {
- 784 struct k_sigaction ka;
- 785 siginfo_t info;
- ...
- 804 signr = get_signal_to_deliver(&info, &ka, regs, NULL);
- ...
- 854 }
-
-And this ``&info`` is what eventually gets passed to ``copy_siginfo()`` as the
-destination argument.
-
-Now, even though we didn't find an actual error here, the example is still a
-good one, because it shows how one would go about to find out what the report
-was all about.
-
-
-Annotating false positives
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-There are a few different ways to make annotations in the source code that
-will keep kmemcheck from checking and reporting certain allocations. Here
-they are:
-
-- ``__GFP_NOTRACK_FALSE_POSITIVE``
- This flag can be passed to ``kmalloc()`` or ``kmem_cache_alloc()``
- (therefore also to other functions that end up calling one of
- these) to indicate that the allocation should not be tracked
- because it would lead to a false positive report. This is a "big
- hammer" way of silencing kmemcheck; after all, even if the false
- positive pertains to particular field in a struct, for example, we
- will now lose the ability to find (real) errors in other parts of
- the same struct.
-
- Example::
-
- /* No warnings will ever trigger on accessing any part of x */
- x = kmalloc(sizeof *x, GFP_KERNEL | __GFP_NOTRACK_FALSE_POSITIVE);
-
-- ``kmemcheck_bitfield_begin(name)``/``kmemcheck_bitfield_end(name)`` and
- ``kmemcheck_annotate_bitfield(ptr, name)``
- The first two of these three macros can be used inside struct
- definitions to signal, respectively, the beginning and end of a
- bitfield. Additionally, this will assign the bitfield a name, which
- is given as an argument to the macros.
-
- Having used these markers, one can later use
- kmemcheck_annotate_bitfield() at the point of allocation, to indicate
- which parts of the allocation is part of a bitfield.
-
- Example::
-
- struct foo {
- int x;
-
- kmemcheck_bitfield_begin(flags);
- int flag_a:1;
- int flag_b:1;
- kmemcheck_bitfield_end(flags);
-
- int y;
- };
-
- struct foo *x = kmalloc(sizeof *x);
-
- /* No warnings will trigger on accessing the bitfield of x */
- kmemcheck_annotate_bitfield(x, flags);
-
- Note that ``kmemcheck_annotate_bitfield()`` can be used even before the
- return value of ``kmalloc()`` is checked -- in other words, passing NULL
- as the first argument is legal (and will do nothing).
-
-
-Reporting errors
-----------------
-
-As we have seen, kmemcheck will produce false positive reports. Therefore, it
-is not very wise to blindly post kmemcheck warnings to mailing lists and
-maintainers. Instead, I encourage maintainers and developers to find errors
-in their own code. If you get a warning, you can try to work around it, try
-to figure out if it's a real error or not, or simply ignore it. Most
-developers know their own code and will quickly and efficiently determine the
-root cause of a kmemcheck report. This is therefore also the most efficient
-way to work with kmemcheck.
-
-That said, we (the kmemcheck maintainers) will always be on the lookout for
-false positives that we can annotate and silence. So whatever you find,
-please drop us a note privately! Kernel configs and steps to reproduce (if
-available) are of course a great help too.
-
-Happy hacking!
-
-
-Technical description
----------------------
-
-kmemcheck works by marking memory pages non-present. This means that whenever
-somebody attempts to access the page, a page fault is generated. The page
-fault handler notices that the page was in fact only hidden, and so it calls
-on the kmemcheck code to make further investigations.
-
-When the investigations are completed, kmemcheck "shows" the page by marking
-it present (as it would be under normal circumstances). This way, the
-interrupted code can continue as usual.
-
-But after the instruction has been executed, we should hide the page again, so
-that we can catch the next access too! Now kmemcheck makes use of a debugging
-feature of the processor, namely single-stepping. When the processor has
-finished the one instruction that generated the memory access, a debug
-exception is raised. From here, we simply hide the page again and continue
-execution, this time with the single-stepping feature turned off.
-
-kmemcheck requires some assistance from the memory allocator in order to work.
-The memory allocator needs to
-
- 1. Tell kmemcheck about newly allocated pages and pages that are about to
- be freed. This allows kmemcheck to set up and tear down the shadow memory
- for the pages in question. The shadow memory stores the status of each
- byte in the allocation proper, e.g. whether it is initialized or
- uninitialized.
-
- 2. Tell kmemcheck which parts of memory should be marked uninitialized.
- There are actually a few more states, such as "not yet allocated" and
- "recently freed".
-
-If a slab cache is set up using the SLAB_NOTRACK flag, it will never return
-memory that can take page faults because of kmemcheck.
-
-If a slab cache is NOT set up using the SLAB_NOTRACK flag, callers can still
-request memory with the __GFP_NOTRACK or __GFP_NOTRACK_FALSE_POSITIVE flags.
-This does not prevent the page faults from occurring, however, but marks the
-object in question as being initialized so that no warnings will ever be
-produced for this object.
-
-Currently, the SLAB and SLUB allocators are supported by kmemcheck.

+Texas Instruments sysc interconnect target module wrapper binding
+
+Texas Instruments SoCs can have a generic interconnect target module
+hardware for devices connected to various interconnects such as L3
+interconnect (Arteris NoC) and L4 interconnect (Sonics s3220). The sysc
+is mostly used for interaction between module and PRCM. It participates
+in the OCP Disconnect Protocol but other than that is mostly independent
+of the interconnect.
+
+Each interconnect target module can have one or more devices connected to
+it. There is a set of control registers for managing interconnect target
+module clocks, idle modes and interconnect level resets for the module.
+
+These control registers are sprinkled into the unused register address
+space of the first child device IP block managed by the interconnect
+target module and typically are named REVISION, SYSCONFIG and SYSSTATUS.
+
+Required standard properties:
+
+- compatible shall be one of the following generic types:
+
+ "ti,sysc-omap2"
+ "ti,sysc-omap4"
+ "ti,sysc-omap4-simple"
+
+ or one of the following derivative types for hardware
+ needing special workarounds:
+
+ "ti,sysc-omap3430-sr"
+ "ti,sysc-omap3630-sr"
+ "ti,sysc-omap4-sr"
+ "ti,sysc-omap3-sham"
+ "ti,sysc-omap-aes"
+ "ti,sysc-mcasp"
+ "ti,sysc-usb-host-fs"
+
+- reg shall have register areas implemented for the interconnect
+ target module in question such as revision, sysc and syss
+
+- reg-names shall contain the register names implemented for the
+ interconnect target module in question such as
+ "rev, "sysc", and "syss"
+
+- ranges shall contain the interconnect target module IO range
+ available for one or more child device IP blocks managed
+ by the interconnect target module, the ranges may include
+ multiple ranges such as device L4 range for control and
+ parent L3 range for DMA access
+
+Optional properties:
+
+- clocks clock specifier for each name in the clock-names as
+ specified in the binding documentation for ti-clkctrl,
+ typically available for all interconnect targets on TI SoCs
+ based on omap4 except if it's read-only register in hwauto
+ mode as for example omap4 L4_CFG_CLKCTRL
+
+- clock-names should contain at least "fck", and optionally also "ick"
+ depending on the SoC and the interconnect target module
+
+- ti,hwmods optional TI interconnect module name to use legacy
+ hwmod platform data
+
+
+Example: Single instance of MUSB controller on omap4 using interconnect ranges
+using offsets from l4_cfg second segment (0x4a000000 + 0x80000 = 0x4a0ab000):
+
+ target-module@2b000 { /* 0x4a0ab000, ap 84 12.0 */
+ compatible = "ti,sysc-omap2";
+ ti,hwmods = "usb_otg_hs";
+ reg = <0x2b400 0x4>,
+ <0x2b404 0x4>,
+ <0x2b408 0x4>;
+ reg-names = "rev", "sysc", "syss";
+ clocks = <&l3_init_clkctrl OMAP4_USB_OTG_HS_CLKCTRL 0>;
+ clock-names = "fck";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <0 0x2b000 0x1000>;
+
+ usb_otg_hs: otg@0 {
+ compatible = "ti,omap4-musb";
+ reg = <0x0 0x7ff>;
+ interrupts = <GIC_SPI 92 IRQ_TYPE_LEVEL_HIGH>,
+ <GIC_SPI 93 IRQ_TYPE_LEVEL_HIGH>;
+ usb-phy = <&usb2_phy>;
+ ...
+ };
+ };
+
+Note that other SoCs, such as am335x can have multipe child devices. On am335x
+there are two MUSB instances, two USB PHY instances, and a single CPPI41 DMA
+instance as children of a single interconnet target module.

+Daisy-chained devices
+---------------------
+
+Many serially-attached GPIO and IIO devices are daisy-chainable. To the
+host controller, a daisy-chain appears as a single device, but the number
+of inputs and outputs it provides is the sum of inputs and outputs provided
+by all of its devices. The driver needs to know how many devices the
+daisy-chain comprises to determine the amount of data exchanged, how many
+inputs and outputs to register and so on.

+Optional properties:

+Amlogic meson GPIO interrupt controller
+
+Meson SoCs contains an interrupt controller which is able to watch the SoC
+pads and generate an interrupt on edge or level. The controller is essentially
+a 256 pads to 8 GIC interrupt multiplexer, with a filter block to select edge
+or level and polarity. It does not expose all 256 mux inputs because the
+documentation shows that the upper part is not mapped to any pad. The actual
+number of interrupt exposed depends on the SoC.
+
+Required properties:
+
+- compatible : must have "amlogic,meson8-gpio-intc†and either
+ “amlogic,meson8-gpio-intc†for meson8 SoCs (S802) or
+ “amlogic,meson8b-gpio-intc†for meson8b SoCs (S805) or
+ “amlogic,meson-gxbb-gpio-intc†for GXBB SoCs (S905) or
+ “amlogic,meson-gxl-gpio-intc†for GXL SoCs (S905X, S912)
+- interrupt-parent : a phandle to the GIC the interrupts are routed to.
+ Usually this is provided at the root level of the device tree as it is
+ common to most of the SoC.
+- reg : Specifies base physical address and size of the registers.
+- interrupt-controller : Identifies the node as an interrupt controller.
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt source. The value must be 2.
+- meson,channel-interrupts: Array with the 8 upstream hwirq numbers. These
+ are the hwirqs used on the parent interrupt controller.
+
+Example:
+
+gpio_interrupt: interrupt-controller@9880 {
+ compatible = "amlogic,meson-gxbb-gpio-intc",
+ "amlogic,meson-gpio-intc";
+ reg = <0x0 0x9880 0x0 0x10>;

+* Amlogic Meson6, Meson8 and Meson8b SDIO/MMC controller
+
+The highspeed MMC host controller on Amlogic SoCs provides an interface
+for MMC, SD, SDIO and SDHC types of memory cards.
+
+Supported maximum speeds are the ones of the eMMC standard 4.41 as well
+as the speed of SD standard 2.0.
+
+The hardware provides an internal "mux" which allows up to three slots
+to be controlled. Only one slot can be accessed at a time.
+
+Required properties:
+ - compatible : must be one of
+ - "amlogic,meson8-sdio"
+ - "amlogic,meson8b-sdio"
+ along with the generic "amlogic,meson-mx-sdio"
+ - reg : mmc controller base registers
+ - interrupts : mmc controller interrupt
+ - #address-cells : must be 1
+ - size-cells : must be 0
+ - clocks : phandle to clock providers
+ - clock-names : must contain "core" and "clkin"
+
+Required child nodes:
+A node for each slot provided by the MMC controller is required.
+NOTE: due to a driver limitation currently only one slot (= child node)
+ is supported!
+
+Required properties on each child node (= slot):
+ - compatible : must be "mmc-slot" (see mmc.txt within this directory)
+ - reg : the slot (or "port") ID
+
+Optional properties on each child node (= slot):
+ - bus-width : must be 1 or 4 (8-bit bus is not supported)
+ - for cd and all other additional generic mmc parameters
+ please refer to mmc.txt within this directory
+
+Examples:
+ mmc@c1108c20 {
+ compatible = "amlogic,meson8-sdio", "amlogic,meson-mx-sdio";
+ reg = <0xc1108c20 0x20>;

+- allwinner,rx-delay-ps: RX clock delay chain value in ps. Range value is 0-3100. Default is 0)
+Both delay properties need to be a multiple of 100. They control the delay for
+external PHY.
+
+Optional properties for the following compatibles:
+ - "allwinner,sun8i-h3-emac",
+ - "allwinner,sun8i-v3s-emac":
+- allwinner,leds-active-low: EPHY LEDs are active low
+
+Required child node of emac:
+- mdio bus node: should be named mdio with compatible "snps,dwmac-mdio"
+
+Required properties of the mdio node:
+- #address-cells: shall be 1
+- #size-cells: shall be 0
+
+The device node referenced by "phy" or "phy-handle" must be a child node
+of the mdio node. See phy.txt for the generic PHY bindings.
+
+The following compatibles require that the emac node have a mdio-mux child
+node called "mdio-mux":
+ - "allwinner,sun8i-h3-emac"
+ - "allwinner,sun8i-v3s-emac":
+Required properties for the mdio-mux node:
+ - compatible = "allwinner,sun8i-h3-mdio-mux"
+ - mdio-parent-bus: a phandle to EMAC mdio
+ - one child mdio for the integrated mdio with the compatible
+ "allwinner,sun8i-h3-mdio-internal"
+ - one child mdio for the external mdio if present (V3s have none)
+Required properties for the mdio-mux children node:
+ - reg: 1 for internal MDIO bus, 2 for external MDIO bus
+
+The following compatibles require a PHY node representing the integrated
+PHY, under the integrated MDIO bus node if an mdio-mux node is used:
+ - "allwinner,sun8i-h3-emac",
+ - "allwinner,sun8i-v3s-emac":
+
+Additional information regarding generic multiplexer properties can be found
+at Documentation/devicetree/bindings/net/mdio-mux.txt

+OpenRISC Generic SoC
+====================
+
+Boards and FPGA SoC's which support the OpenRISC standard platform. The
+platform essentially follows the conventions of the OpenRISC architecture
+specification, however some aspects, such as the boot protocol have been defined
+by the Linux port.
+
+Required properties
+-------------------
+ - compatible: Must include "opencores,or1ksim"
+
+CPU nodes:
+----------
+A "cpus" node is required. Required properties:
+ - #address-cells: Must be 1.
+ - #size-cells: Must be 0.
+A CPU sub-node is also required for at least CPU 0. Since the topology may
+be probed via CPS, it is not necessary to specify secondary CPUs. Required
+properties:
+ - compatible: Must be "opencores,or1200-rtlsvn481".
+ - reg: CPU number.
+ - clock-frequency: The CPU clock frequency in Hz.
+Example:
+ cpus {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ cpu@0 {
+ compatible = "opencores,or1200-rtlsvn481";
+ reg = <0>;
+ clock-frequency = <20000000>;
+ };
+ };
+
+
+Boot protocol
+-------------
+The bootloader may pass the following arguments to the kernel:
+ - r3: address of a flattened device-tree blob or 0x0.

+* Synopsys DesignWare PCIe root complex in ECAM shift mode
+
+In some cases, firmware may already have configured the Synopsys DesignWare
+PCIe controller in RC mode with static ATU window mappings that cover all
+config, MMIO and I/O spaces in a [mostly] ECAM compatible fashion.
+In this case, there is no need for the OS to perform any low level setup
+of clocks, PHYs or device registers, nor is there any reason for the driver
+to reconfigure ATU windows for config and/or IO space accesses at runtime.
+
+In cases where the IP was synthesized with a minimum ATU window size of
+64 KB, it cannot be supported by the generic ECAM driver, because it
+requires special config space accessors that filter accesses to device #1
+and beyond on the first bus.
+
+Required properties:
+- compatible: "marvell,armada8k-pcie-ecam" or
+ "socionext,synquacer-pcie-ecam" or
+ "snps,dw-pcie-ecam" (must be preceded by a more specific match)
+
+Please refer to the binding document of "pci-host-ecam-generic" in the
+file host-generic-pci.txt for a description of the remaining required
+and optional properties.

+Amlogic Meson Power Controller
+==============================
+
+The Amlogic Meson SoCs embeds an internal Power domain controller.
+
+VPU Power Domain
+----------------
+
+The Video Processing Unit power domain is controlled by this power controller,
+but the domain requires some external resources to meet the correct power
+sequences.
+The bindings must respect the power domain bindings as described in the file
+power_domain.txt
+
+Device Tree Bindings:
+---------------------
+
+Required properties:
+- compatible: should be "amlogic,meson-gx-pwrc-vpu" for the Meson GX SoCs
+- #power-domain-cells: should be 0
+- amlogic,hhi-sysctrl: phandle to the HHI sysctrl node
+- resets: phandles to the reset lines needed for this power demain sequence
+ as described in ../reset/reset.txt
+- clocks: from common clock binding: handle to VPU and VAPB clocks
+- clock-names: from common clock binding: must contain "vpu", "vapb"
+ corresponding to entry in the clocks property.
+
+Parent node should have the following properties :
+- compatible: "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd"
+- reg: base address and size of the AO system control register space.
+
+Example:
+-------
+
+ao_sysctrl: sys-ctrl@0 {
+ compatible = "amlogic,meson-gx-ao-sysctrl", "syscon", "simple-mfd";
+ reg = <0x0 0x0 0x0 0x100>;

+===================
+RISC-V CPU Bindings
+===================
+
+The device tree allows to describe the layout of CPUs in a system through
+the "cpus" node, which in turn contains a number of subnodes (ie "cpu")
+defining properties for every cpu.
+
+Bindings for CPU nodes follow the Devicetree Specification, available from:
+
+https://www.devicetree.org/specifications/
+
+with updates for 32-bit and 64-bit RISC-V systems provided in this document.
+
+===========
+Terminology
+===========
+
+This document uses some terminology common to the RISC-V community that is not
+widely used, the definitions of which are listed here:
+
+* hart: A hardware execution context, which contains all the state mandated by
+ the RISC-V ISA: a PC and some registers. This terminology is designed to
+ disambiguate software's view of execution contexts from any particular
+ microarchitectural implementation strategy. For example, my Intel laptop is
+ described as having one socket with two cores, each of which has two hyper
+ threads. Therefore this system has four harts.
+
+=====================================
+cpus and cpu node bindings definition
+=====================================
+
+The RISC-V architecture, in accordance with the Devicetree Specification,
+requires the cpus and cpu nodes to be present and contain the properties
+described below.
+
+- cpus node
+
+ Description: Container of cpu nodes
+
+ The node name must be "cpus".
+
+ A cpus node must define the following properties:
+
+ - #address-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be set to 1
+ - #size-cells
+ Usage: required
+ Value type: <u32>
+ Definition: must be set to 0
+
+- cpu node
+
+ Description: Describes a hart context
+
+ PROPERTIES
+
+ - device_type
+ Usage: required
+ Value type: <string>
+ Definition: must be "cpu"
+ - reg
+ Usage: required
+ Value type: <u32>
+ Definition: The hart ID of this CPU node
+ - compatible:
+ Usage: required
+ Value type: <stringlist>
+ Definition: must contain "riscv", may contain one of
+ "sifive,rocket0"
+ - mmu-type:
+ Usage: optional
+ Value type: <string>
+ Definition: Specifies the CPU's MMU type. Possible values are
+ "riscv,sv32"
+ "riscv,sv39"
+ "riscv,sv48"
+ - riscv,isa:
+ Usage: required
+ Value type: <string>
+ Definition: Contains the RISC-V ISA string of this hart. These
+ ISA strings are defined by the RISC-V ISA manual.
+
+Example: SiFive Freedom U540G Development Kit
+---------------------------------------------
+
+This system contains two harts: a hart marked as disabled that's used for
+low-level system tasks and should be ignored by Linux, and a second hart that
+Linux is allowed to run on.

+Spreadtrum ADI controller
+
+ADI is the abbreviation of Anolog-Digital interface, which is used to access
+analog chip (such as PMIC) from digital chip. ADI controller follows the SPI
+framework for its hardware implementation is alike to SPI bus and its timing
+is compatile to SPI timing.
+
+ADI controller has 50 channels including 2 software read/write channels and
+48 hardware channels to access analog chip. For 2 software read/write channels,
+users should set ADI registers to access analog chip. For hardware channels,
+we can configure them to allow other hardware components to use it independently,
+which means we can just link one analog chip address to one hardware channel,
+then users can access the mapped analog chip address by this hardware channel
+triggered by hardware components instead of ADI software channels.
+
+Thus we introduce one property named "sprd,hw-channels" to configure hardware
+channels, the first value specifies the hardware channel id which is used to
+transfer data triggered by hardware automatically, and the second value specifies
+the analog chip address where user want to access by hardware components.
+
+Since we have multi-subsystems will use unique ADI to access analog chip, when
+one system is reading/writing data by ADI software channels, that should be under
+one hardware spinlock protection to prevent other systems from reading/writing
+data by ADI software channels at the same time, or two parallel routine of setting
+ADI registers will make ADI controller registers chaos to lead incorrect results.
+Then we need one hardware spinlock to synchronize between the multiple subsystems.
+
+Required properties:
+- compatible: Should be "sprd,sc9860-adi".
+- reg: Offset and length of ADI-SPI controller register space.
+- hwlocks: Reference to a phandle of a hwlock provider node.
+- hwlock-names: Reference to hwlock name strings defined in the same order
+ as the hwlocks, should be "adi".
+- #address-cells: Number of cells required to define a chip select address
+ on the ADI-SPI bus. Should be set to 1.
+- #size-cells: Size of cells required to define a chip select address size
+ on the ADI-SPI bus. Should be set to 0.
+
+Optional properties:
+- sprd,hw-channels: This is an array of channel values up to 49 channels.
+ The first value specifies the hardware channel id which is used to
+ transfer data triggered by hardware automatically, and the second
+ value specifies the analog chip address where user want to access
+ by hardware components.
+
+SPI slave nodes must be children of the SPI controller node and can contain
+properties described in Documentation/devicetree/bindings/spi/spi-bus.txt.
+
+Example:
+ adi_bus: spi@40030000 {
+ compatible = "sprd,sc9860-adi";
+ reg = <0 0x40030000 0 0x10000>;

- DMA Engine API Guide
- ====================
-
- Vinod Koul <vinod dot koul at intel.com>
-
-NOTE: For DMA Engine usage in async_tx please see:
- Documentation/crypto/async-tx-api.txt
-
-
-Below is a guide to device driver writers on how to use the Slave-DMA API of the
-DMA Engine. This is applicable only for slave DMA usage only.
-
-The slave DMA usage consists of following steps:
-1. Allocate a DMA slave channel
-2. Set slave and controller specific parameters
-3. Get a descriptor for transaction
-4. Submit the transaction
-5. Issue pending requests and wait for callback notification
-
-1. Allocate a DMA slave channel
-
- Channel allocation is slightly different in the slave DMA context,
- client drivers typically need a channel from a particular DMA
- controller only and even in some cases a specific channel is desired.
- To request a channel dma_request_chan() API is used.
-
- Interface:
- struct dma_chan *dma_request_chan(struct device *dev, const char *name);
-
- Which will find and return the 'name' DMA channel associated with the 'dev'
- device. The association is done via DT, ACPI or board file based
- dma_slave_map matching table.
-
- A channel allocated via this interface is exclusive to the caller,
- until dma_release_channel() is called.
-
-2. Set slave and controller specific parameters
-
- Next step is always to pass some specific information to the DMA
- driver. Most of the generic information which a slave DMA can use
- is in struct dma_slave_config. This allows the clients to specify
- DMA direction, DMA addresses, bus widths, DMA burst lengths etc
- for the peripheral.
-
- If some DMA controllers have more parameters to be sent then they
- should try to embed struct dma_slave_config in their controller
- specific structure. That gives flexibility to client to pass more
- parameters, if required.
-
- Interface:
- int dmaengine_slave_config(struct dma_chan *chan,
- struct dma_slave_config *config)
-
- Please see the dma_slave_config structure definition in dmaengine.h
- for a detailed explanation of the struct members. Please note
- that the 'direction' member will be going away as it duplicates the
- direction given in the prepare call.
-
-3. Get a descriptor for transaction
-
- For slave usage the various modes of slave transfers supported by the
- DMA-engine are:
-
- slave_sg - DMA a list of scatter gather buffers from/to a peripheral
- dma_cyclic - Perform a cyclic DMA operation from/to a peripheral till the
- operation is explicitly stopped.
- interleaved_dma - This is common to Slave as well as M2M clients. For slave
- address of devices' fifo could be already known to the driver.
- Various types of operations could be expressed by setting
- appropriate values to the 'dma_interleaved_template' members.
-
- A non-NULL return of this transfer API represents a "descriptor" for
- the given transaction.
-
- Interface:
- struct dma_async_tx_descriptor *dmaengine_prep_slave_sg(
- struct dma_chan *chan, struct scatterlist *sgl,
- unsigned int sg_len, enum dma_data_direction direction,
- unsigned long flags);
-
- struct dma_async_tx_descriptor *dmaengine_prep_dma_cyclic(
- struct dma_chan *chan, dma_addr_t buf_addr, size_t buf_len,
- size_t period_len, enum dma_data_direction direction);
-
- struct dma_async_tx_descriptor *dmaengine_prep_interleaved_dma(
- struct dma_chan *chan, struct dma_interleaved_template *xt,
- unsigned long flags);
-
- The peripheral driver is expected to have mapped the scatterlist for
- the DMA operation prior to calling dmaengine_prep_slave_sg(), and must
- keep the scatterlist mapped until the DMA operation has completed.
- The scatterlist must be mapped using the DMA struct device.
- If a mapping needs to be synchronized later, dma_sync_*_for_*() must be
- called using the DMA struct device, too.
- So, normal setup should look like this:
-
- nr_sg = dma_map_sg(chan->device->dev, sgl, sg_len);
- if (nr_sg == 0)
- /* error */
-
- desc = dmaengine_prep_slave_sg(chan, sgl, nr_sg, direction, flags);
-
- Once a descriptor has been obtained, the callback information can be
- added and the descriptor must then be submitted. Some DMA engine
- drivers may hold a spinlock between a successful preparation and
- submission so it is important that these two operations are closely
- paired.
-
- Note:
- Although the async_tx API specifies that completion callback
- routines cannot submit any new operations, this is not the
- case for slave/cyclic DMA.
-
- For slave DMA, the subsequent transaction may not be available
- for submission prior to callback function being invoked, so
- slave DMA callbacks are permitted to prepare and submit a new
- transaction.
-
- For cyclic DMA, a callback function may wish to terminate the
- DMA via dmaengine_terminate_async().
-
- Therefore, it is important that DMA engine drivers drop any
- locks before calling the callback function which may cause a
- deadlock.
-
- Note that callbacks will always be invoked from the DMA
- engines tasklet, never from interrupt context.
-
-4. Submit the transaction
-
- Once the descriptor has been prepared and the callback information
- added, it must be placed on the DMA engine drivers pending queue.
-
- Interface:
- dma_cookie_t dmaengine_submit(struct dma_async_tx_descriptor *desc)
-
- This returns a cookie can be used to check the progress of DMA engine
- activity via other DMA engine calls not covered in this document.
-
- dmaengine_submit() will not start the DMA operation, it merely adds
- it to the pending queue. For this, see step 5, dma_async_issue_pending.
-
-5. Issue pending DMA requests and wait for callback notification
-
- The transactions in the pending queue can be activated by calling the
- issue_pending API. If channel is idle then the first transaction in
- queue is started and subsequent ones queued up.
-
- On completion of each DMA operation, the next in queue is started and
- a tasklet triggered. The tasklet will then call the client driver
- completion callback routine for notification, if set.
-
- Interface:
- void dma_async_issue_pending(struct dma_chan *chan);
-
-Further APIs:
-
-1. int dmaengine_terminate_sync(struct dma_chan *chan)
- int dmaengine_terminate_async(struct dma_chan *chan)
- int dmaengine_terminate_all(struct dma_chan *chan) /* DEPRECATED */
-
- This causes all activity for the DMA channel to be stopped, and may
- discard data in the DMA FIFO which hasn't been fully transferred.
- No callback functions will be called for any incomplete transfers.
-
- Two variants of this function are available.
-
- dmaengine_terminate_async() might not wait until the DMA has been fully
- stopped or until any running complete callbacks have finished. But it is
- possible to call dmaengine_terminate_async() from atomic context or from
- within a complete callback. dmaengine_synchronize() must be called before it
- is safe to free the memory accessed by the DMA transfer or free resources
- accessed from within the complete callback.
-
- dmaengine_terminate_sync() will wait for the transfer and any running
- complete callbacks to finish before it returns. But the function must not be
- called from atomic context or from within a complete callback.
-
- dmaengine_terminate_all() is deprecated and should not be used in new code.
-
-2. int dmaengine_pause(struct dma_chan *chan)
-
- This pauses activity on the DMA channel without data loss.
-
-3. int dmaengine_resume(struct dma_chan *chan)
-
- Resume a previously paused DMA channel. It is invalid to resume a
- channel which is not currently paused.
-
-4. enum dma_status dma_async_is_tx_complete(struct dma_chan *chan,
- dma_cookie_t cookie, dma_cookie_t *last, dma_cookie_t *used)
-
- This can be used to check the status of the channel. Please see
- the documentation in include/linux/dmaengine.h for a more complete
- description of this API.
-
- This can be used in conjunction with dma_async_is_complete() and
- the cookie returned from dmaengine_submit() to check for
- completion of a specific DMA transaction.
-
- Note:
- Not all DMA engine drivers can return reliable information for
- a running DMA channel. It is recommended that DMA engine users
- pause or stop (via dmaengine_terminate_all()) the channel before
- using this API.
-
-5. void dmaengine_synchronize(struct dma_chan *chan)
-
- Synchronize the termination of the DMA channel to the current context.
-
- This function should be used after dmaengine_terminate_async() to synchronize
- the termination of the DMA channel to the current context. The function will
- wait for the transfer and any running complete callbacks to finish before it
- returns.
-
- If dmaengine_terminate_async() is used to stop the DMA channel this function
- must be called before it is safe to free memory accessed by previously
- submitted descriptors or to free any resources accessed within the complete
- callback of previously submitted descriptors.
-
- The behavior of this function is undefined if dma_async_issue_pending() has
- been called between dmaengine_terminate_async() and this function.

-DMAengine controller documentation
-==================================
-
-Hardware Introduction
-+++++++++++++++++++++
-
-Most of the Slave DMA controllers have the same general principles of
-operations.
-
-They have a given number of channels to use for the DMA transfers, and
-a given number of requests lines.
-
-Requests and channels are pretty much orthogonal. Channels can be used
-to serve several to any requests. To simplify, channels are the
-entities that will be doing the copy, and requests what endpoints are
-involved.
-
-The request lines actually correspond to physical lines going from the
-DMA-eligible devices to the controller itself. Whenever the device
-will want to start a transfer, it will assert a DMA request (DRQ) by
-asserting that request line.
-
-A very simple DMA controller would only take into account a single
-parameter: the transfer size. At each clock cycle, it would transfer a
-byte of data from one buffer to another, until the transfer size has
-been reached.
-
-That wouldn't work well in the real world, since slave devices might
-require a specific number of bits to be transferred in a single
-cycle. For example, we may want to transfer as much data as the
-physical bus allows to maximize performances when doing a simple
-memory copy operation, but our audio device could have a narrower FIFO
-that requires data to be written exactly 16 or 24 bits at a time. This
-is why most if not all of the DMA controllers can adjust this, using a
-parameter called the transfer width.
-
-Moreover, some DMA controllers, whenever the RAM is used as a source
-or destination, can group the reads or writes in memory into a buffer,
-so instead of having a lot of small memory accesses, which is not
-really efficient, you'll get several bigger transfers. This is done
-using a parameter called the burst size, that defines how many single
-reads/writes it's allowed to do without the controller splitting the
-transfer into smaller sub-transfers.
-
-Our theoretical DMA controller would then only be able to do transfers
-that involve a single contiguous block of data. However, some of the
-transfers we usually have are not, and want to copy data from
-non-contiguous buffers to a contiguous buffer, which is called
-scatter-gather.
-
-DMAEngine, at least for mem2dev transfers, require support for
-scatter-gather. So we're left with two cases here: either we have a
-quite simple DMA controller that doesn't support it, and we'll have to
-implement it in software, or we have a more advanced DMA controller,
-that implements in hardware scatter-gather.
-
-The latter are usually programmed using a collection of chunks to
-transfer, and whenever the transfer is started, the controller will go
-over that collection, doing whatever we programmed there.
-
-This collection is usually either a table or a linked list. You will
-then push either the address of the table and its number of elements,
-or the first item of the list to one channel of the DMA controller,
-and whenever a DRQ will be asserted, it will go through the collection
-to know where to fetch the data from.
-
-Either way, the format of this collection is completely dependent on
-your hardware. Each DMA controller will require a different structure,
-but all of them will require, for every chunk, at least the source and
-destination addresses, whether it should increment these addresses or
-not and the three parameters we saw earlier: the burst size, the
-transfer width and the transfer size.
-
-The one last thing is that usually, slave devices won't issue DRQ by
-default, and you have to enable this in your slave device driver first
-whenever you're willing to use DMA.
-
-These were just the general memory-to-memory (also called mem2mem) or
-memory-to-device (mem2dev) kind of transfers. Most devices often
-support other kind of transfers or memory operations that dmaengine
-support and will be detailed later in this document.
-
-DMA Support in Linux
-++++++++++++++++++++
-
-Historically, DMA controller drivers have been implemented using the
-async TX API, to offload operations such as memory copy, XOR,
-cryptography, etc., basically any memory to memory operation.
-
-Over time, the need for memory to device transfers arose, and
-dmaengine was extended. Nowadays, the async TX API is written as a
-layer on top of dmaengine, and acts as a client. Still, dmaengine
-accommodates that API in some cases, and made some design choices to
-ensure that it stayed compatible.
-
-For more information on the Async TX API, please look the relevant
-documentation file in Documentation/crypto/async-tx-api.txt.
-
-DMAEngine Registration
-++++++++++++++++++++++
-
-struct dma_device Initialization
---------------------------------
-
-Just like any other kernel framework, the whole DMAEngine registration
-relies on the driver filling a structure and registering against the
-framework. In our case, that structure is dma_device.
-
-The first thing you need to do in your driver is to allocate this
-structure. Any of the usual memory allocators will do, but you'll also
-need to initialize a few fields in there:
-
- * channels: should be initialized as a list using the
- INIT_LIST_HEAD macro for example
-
- * src_addr_widths:
- - should contain a bitmask of the supported source transfer width
-
- * dst_addr_widths:
- - should contain a bitmask of the supported destination transfer
- width
-
- * directions:
- - should contain a bitmask of the supported slave directions
- (i.e. excluding mem2mem transfers)
-
- * residue_granularity:
- - Granularity of the transfer residue reported to dma_set_residue.
- - This can be either:
- + Descriptor
- -> Your device doesn't support any kind of residue
- reporting. The framework will only know that a particular
- transaction descriptor is done.
- + Segment
- -> Your device is able to report which chunks have been
- transferred
- + Burst
- -> Your device is able to report which burst have been
- transferred
-
- * dev: should hold the pointer to the struct device associated
- to your current driver instance.
-
-Supported transaction types
----------------------------
-
-The next thing you need is to set which transaction types your device
-(and driver) supports.
-
-Our dma_device structure has a field called cap_mask that holds the
-various types of transaction supported, and you need to modify this
-mask using the dma_cap_set function, with various flags depending on
-transaction types you support as an argument.
-
-All those capabilities are defined in the dma_transaction_type enum,
-in include/linux/dmaengine.h
-
-Currently, the types available are:
- * DMA_MEMCPY
- - The device is able to do memory to memory copies
-
- * DMA_XOR
- - The device is able to perform XOR operations on memory areas
- - Used to accelerate XOR intensive tasks, such as RAID5
-
- * DMA_XOR_VAL
- - The device is able to perform parity check using the XOR
- algorithm against a memory buffer.
-
- * DMA_PQ
- - The device is able to perform RAID6 P+Q computations, P being a
- simple XOR, and Q being a Reed-Solomon algorithm.
-
- * DMA_PQ_VAL
- - The device is able to perform parity check using RAID6 P+Q
- algorithm against a memory buffer.
-
- * DMA_INTERRUPT
- - The device is able to trigger a dummy transfer that will
- generate periodic interrupts
- - Used by the client drivers to register a callback that will be
- called on a regular basis through the DMA controller interrupt
-
- * DMA_PRIVATE
- - The devices only supports slave transfers, and as such isn't
- available for async transfers.
-
- * DMA_ASYNC_TX
- - Must not be set by the device, and will be set by the framework
- if needed
- - /* TODO: What is it about? */
-
- * DMA_SLAVE
- - The device can handle device to memory transfers, including
- scatter-gather transfers.
- - While in the mem2mem case we were having two distinct types to
- deal with a single chunk to copy or a collection of them, here,
- we just have a single transaction type that is supposed to
- handle both.
- - If you want to transfer a single contiguous memory buffer,
- simply build a scatter list with only one item.
-
- * DMA_CYCLIC
- - The device can handle cyclic transfers.
- - A cyclic transfer is a transfer where the chunk collection will
- loop over itself, with the last item pointing to the first.
- - It's usually used for audio transfers, where you want to operate
- on a single ring buffer that you will fill with your audio data.
-
- * DMA_INTERLEAVE
- - The device supports interleaved transfer.
- - These transfers can transfer data from a non-contiguous buffer
- to a non-contiguous buffer, opposed to DMA_SLAVE that can
- transfer data from a non-contiguous data set to a continuous
- destination buffer.
- - It's usually used for 2d content transfers, in which case you
- want to transfer a portion of uncompressed data directly to the
- display to print it
-
-These various types will also affect how the source and destination
-addresses change over time.
-
-Addresses pointing to RAM are typically incremented (or decremented)
-after each transfer. In case of a ring buffer, they may loop
-(DMA_CYCLIC). Addresses pointing to a device's register (e.g. a FIFO)
-are typically fixed.
-
-Device operations
------------------
-
-Our dma_device structure also requires a few function pointers in
-order to implement the actual logic, now that we described what
-operations we were able to perform.
-
-The functions that we have to fill in there, and hence have to
-implement, obviously depend on the transaction types you reported as
-supported.
-
- * device_alloc_chan_resources
- * device_free_chan_resources
- - These functions will be called whenever a driver will call
- dma_request_channel or dma_release_channel for the first/last
- time on the channel associated to that driver.
- - They are in charge of allocating/freeing all the needed
- resources in order for that channel to be useful for your
- driver.
- - These functions can sleep.
-
- * device_prep_dma_*
- - These functions are matching the capabilities you registered
- previously.
- - These functions all take the buffer or the scatterlist relevant
- for the transfer being prepared, and should create a hardware
- descriptor or a list of hardware descriptors from it
- - These functions can be called from an interrupt context
- - Any allocation you might do should be using the GFP_NOWAIT
- flag, in order not to potentially sleep, but without depleting
- the emergency pool either.
- - Drivers should try to pre-allocate any memory they might need
- during the transfer setup at probe time to avoid putting to
- much pressure on the nowait allocator.
-
- - It should return a unique instance of the
- dma_async_tx_descriptor structure, that further represents this
- particular transfer.
-
- - This structure can be initialized using the function
- dma_async_tx_descriptor_init.
- - You'll also need to set two fields in this structure:
- + flags:
- TODO: Can it be modified by the driver itself, or
- should it be always the flags passed in the arguments
-
- + tx_submit: A pointer to a function you have to implement,
- that is supposed to push the current
- transaction descriptor to a pending queue, waiting
- for issue_pending to be called.
- - In this structure the function pointer callback_result can be
- initialized in order for the submitter to be notified that a
- transaction has completed. In the earlier code the function pointer
- callback has been used. However it does not provide any status to the
- transaction and will be deprecated. The result structure defined as
- dmaengine_result that is passed in to callback_result has two fields:
- + result: This provides the transfer result defined by
- dmaengine_tx_result. Either success or some error
- condition.
- + residue: Provides the residue bytes of the transfer for those that
- support residue.
-
- * device_issue_pending
- - Takes the first transaction descriptor in the pending queue,
- and starts the transfer. Whenever that transfer is done, it
- should move to the next transaction in the list.
- - This function can be called in an interrupt context
-
- * device_tx_status
- - Should report the bytes left to go over on the given channel
- - Should only care about the transaction descriptor passed as
- argument, not the currently active one on a given channel
- - The tx_state argument might be NULL
- - Should use dma_set_residue to report it
- - In the case of a cyclic transfer, it should only take into
- account the current period.
- - This function can be called in an interrupt context.
-
- * device_config
- - Reconfigures the channel with the configuration given as
- argument
- - This command should NOT perform synchronously, or on any
- currently queued transfers, but only on subsequent ones
- - In this case, the function will receive a dma_slave_config
- structure pointer as an argument, that will detail which
- configuration to use.
- - Even though that structure contains a direction field, this
- field is deprecated in favor of the direction argument given to
- the prep_* functions
- - This call is mandatory for slave operations only. This should NOT be
- set or expected to be set for memcpy operations.
- If a driver support both, it should use this call for slave
- operations only and not for memcpy ones.
-
- * device_pause
- - Pauses a transfer on the channel
- - This command should operate synchronously on the channel,
- pausing right away the work of the given channel
-
- * device_resume
- - Resumes a transfer on the channel
- - This command should operate synchronously on the channel,
- resuming right away the work of the given channel
-
- * device_terminate_all
- - Aborts all the pending and ongoing transfers on the channel
- - For aborted transfers the complete callback should not be called
- - Can be called from atomic context or from within a complete
- callback of a descriptor. Must not sleep. Drivers must be able
- to handle this correctly.
- - Termination may be asynchronous. The driver does not have to
- wait until the currently active transfer has completely stopped.
- See device_synchronize.
-
- * device_synchronize
- - Must synchronize the termination of a channel to the current
- context.
- - Must make sure that memory for previously submitted
- descriptors is no longer accessed by the DMA controller.
- - Must make sure that all complete callbacks for previously
- submitted descriptors have finished running and none are
- scheduled to run.
- - May sleep.
-
-
-Misc notes (stuff that should be documented, but don't really know
-where to put them)
-------------------------------------------------------------------
- * dma_run_dependencies
- - Should be called at the end of an async TX transfer, and can be
- ignored in the slave transfers case.
- - Makes sure that dependent operations are run before marking it
- as complete.
-
- * dma_cookie_t
- - it's a DMA transaction ID that will increment over time.
- - Not really relevant any more since the introduction of virt-dma
- that abstracts it away.
-
- * DMA_CTRL_ACK
- - If clear, the descriptor cannot be reused by provider until the
- client acknowledges receipt, i.e. has has a chance to establish any
- dependency chains
- - This can be acked by invoking async_tx_ack()
- - If set, does not mean descriptor can be reused
-
- * DMA_CTRL_REUSE
- - If set, the descriptor can be reused after being completed. It should
- not be freed by provider if this flag is set.
- - The descriptor should be prepared for reuse by invoking
- dmaengine_desc_set_reuse() which will set DMA_CTRL_REUSE.
- - dmaengine_desc_set_reuse() will succeed only when channel support
- reusable descriptor as exhibited by capabilities
- - As a consequence, if a device driver wants to skip the dma_map_sg() and
- dma_unmap_sg() in between 2 transfers, because the DMA'd data wasn't used,
- it can resubmit the transfer right after its completion.
- - Descriptor can be freed in few ways
- - Clearing DMA_CTRL_REUSE by invoking dmaengine_desc_clear_reuse()
- and submitting for last txn
- - Explicitly invoking dmaengine_desc_free(), this can succeed only
- when DMA_CTRL_REUSE is already set
- - Terminating the channel
-
- * DMA_PREP_CMD
- - If set, the client driver tells DMA controller that passed data in DMA
- API is command data.
- - Interpretation of command data is DMA controller specific. It can be
- used for issuing commands to other peripherals/register reads/register
- writes for which the descriptor should be in different format from
- normal data descriptors.
-
-General Design Notes
---------------------
-
-Most of the DMAEngine drivers you'll see are based on a similar design
-that handles the end of transfer interrupts in the handler, but defer
-most work to a tasklet, including the start of a new transfer whenever
-the previous transfer ended.
-
-This is a rather inefficient design though, because the inter-transfer
-latency will be not only the interrupt latency, but also the
-scheduling latency of the tasklet, which will leave the channel idle
-in between, which will slow down the global transfer rate.
-
-You should avoid this kind of practice, and instead of electing a new
-transfer in your tasklet, move that part to the interrupt handler in
-order to have a shorter idle window (that we can't really avoid
-anyway).
-
-Glossary

-Burst: A number of consecutive read or write operations
- that can be queued to buffers before being flushed to
- memory.
-Chunk: A contiguous collection of bursts
-Transfer: A collection of chunks (be it contiguous or not)

-PXA/MMP - DMA Slave controller
-==============================
-
-Constraints
------------
- a) Transfers hot queuing
- A driver submitting a transfer and issuing it should be granted the transfer
- is queued even on a running DMA channel.
- This implies that the queuing doesn't wait for the previous transfer end,
- and that the descriptor chaining is not only done in the irq/tasklet code
- triggered by the end of the transfer.
- A transfer which is submitted and issued on a phy doesn't wait for a phy to
- stop and restart, but is submitted on a "running channel". The other
- drivers, especially mmp_pdma waited for the phy to stop before relaunching
- a new transfer.
-
- b) All transfers having asked for confirmation should be signaled
- Any issued transfer with DMA_PREP_INTERRUPT should trigger a callback call.
- This implies that even if an irq/tasklet is triggered by end of tx1, but
- at the time of irq/dma tx2 is already finished, tx1->complete() and
- tx2->complete() should be called.
-
- c) Channel running state
- A driver should be able to query if a channel is running or not. For the
- multimedia case, such as video capture, if a transfer is submitted and then
- a check of the DMA channel reports a "stopped channel", the transfer should
- not be issued until the next "start of frame interrupt", hence the need to
- know if a channel is in running or stopped state.
-
- d) Bandwidth guarantee
- The PXA architecture has 4 levels of DMAs priorities : high, normal, low.
- The high priorities get twice as much bandwidth as the normal, which get twice
- as much as the low priorities.
- A driver should be able to request a priority, especially the real-time
- ones such as pxa_camera with (big) throughputs.
-
-Design
-------
- a) Virtual channels
- Same concept as in sa11x0 driver, ie. a driver was assigned a "virtual
- channel" linked to the requestor line, and the physical DMA channel is
- assigned on the fly when the transfer is issued.
-
- b) Transfer anatomy for a scatter-gather transfer
- +------------+-----+---------------+----------------+-----------------+
- | desc-sg[0] | ... | desc-sg[last] | status updater | finisher/linker |
- +------------+-----+---------------+----------------+-----------------+
-
- This structure is pointed by dma->sg_cpu.
- The descriptors are used as follows :
- - desc-sg[i]: i-th descriptor, transferring the i-th sg
- element to the video buffer scatter gather
- - status updater
- Transfers a single u32 to a well known dma coherent memory to leave
- a trace that this transfer is done. The "well known" is unique per
- physical channel, meaning that a read of this value will tell which
- is the last finished transfer at that point in time.
- - finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
- - linker: has ddadr= desc-sg[0] of next transfer, dcmd=0
-
- c) Transfers hot-chaining
- Suppose the running chain is :
- Buffer 1 Buffer 2
- +---------+----+---+ +----+----+----+---+
- | d0 | .. | dN | l | | d0 | .. | dN | f |
- +---------+----+-|-+ ^----+----+----+---+
- | |
- +----+
-
- After a call to dmaengine_submit(b3), the chain will look like :
- Buffer 1 Buffer 2 Buffer 3
- +---------+----+---+ +----+----+----+---+ +----+----+----+---+
- | d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
- +---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
- | | | |
- +----+ +----+
- new_link
-
- If while new_link was created the DMA channel stopped, it is _not_
- restarted. Hot-chaining doesn't break the assumption that
- dma_async_issue_pending() is to be used to ensure the transfer is actually started.
-
- One exception to this rule :
- - if Buffer1 and Buffer2 had all their addresses 8 bytes aligned
- - and if Buffer3 has at least one address not 4 bytes aligned
- - then hot-chaining cannot happen, as the channel must be stopped, the
- "align bit" must be set, and the channel restarted As a consequence,
- such a transfer tx_submit() will be queued on the submitted queue, and
- this specific case if the DMA is already running in aligned mode.
-
- d) Transfers completion updater
- Each time a transfer is completed on a channel, an interrupt might be
- generated or not, up to the client's request. But in each case, the last
- descriptor of a transfer, the "status updater", will write the latest
- transfer being completed into the physical channel's completion mark.
-
- This will speed up residue calculation, for large transfers such as video
- buffers which hold around 6k descriptors or more. This also allows without
- any lock to find out what is the latest completed transfer in a running
- DMA chain.
-
- e) Transfers completion, irq and tasklet
- When a transfer flagged as "DMA_PREP_INTERRUPT" is finished, the dma irq
- is raised. Upon this interrupt, a tasklet is scheduled for the physical
- channel.
- The tasklet is responsible for :
- - reading the physical channel last updater mark
- - calling all the transfer callbacks of finished transfers, based on
- that mark, and each transfer flags.
- If a transfer is completed while this handling is done, a dma irq will
- be raised, and the tasklet will be scheduled once again, having a new
- updater mark.
-
- f) Residue
- Residue granularity will be descriptor based. The issued but not completed
- transfers will be scanned for all of their descriptors against the
- currently running descriptor.
-
- g) Most complicated case of driver's tx queues
- The most tricky situation is when :
- - there are not "acked" transfers (tx0)
- - a driver submitted an aligned tx1, not chained
- - a driver submitted an aligned tx2 => tx2 is cold chained to tx1
- - a driver issued tx1+tx2 => channel is running in aligned mode
- - a driver submitted an aligned tx3 => tx3 is hot-chained
- - a driver submitted an unaligned tx4 => tx4 is put in submitted queue,
- not chained
- - a driver issued tx4 => tx4 is put in issued queue, not chained
- - a driver submitted an aligned tx5 => tx5 is put in submitted queue, not
- chained
- - a driver submitted an aligned tx6 => tx6 is put in submitted queue,
- cold chained to tx5
-
- This translates into (after tx4 is issued) :
- - issued queue
- +-----+ +-----+ +-----+ +-----+
- | tx1 | | tx2 | | tx3 | | tx4 |
- +---|-+ ^---|-+ ^-----+ +-----+
- | | | |
- +---+ +---+
- - submitted queue
- +-----+ +-----+
- | tx5 | | tx6 |
- +---|-+ ^-----+
- | |
- +---+
- - completed queue : empty
- - allocated queue : tx0
-
- It should be noted that after tx3 is completed, the channel is stopped, and
- restarted in "unaligned mode" to handle tx4.

+====================
+DMA Engine API Guide
+====================
+
+Vinod Koul <vinod dot koul at intel.com>
+
+.. note:: For DMA Engine usage in async_tx please see:
+ ``Documentation/crypto/async-tx-api.txt``
+
+
+Below is a guide to device driver writers on how to use the Slave-DMA API of the
+DMA Engine. This is applicable only for slave DMA usage only.
+
+DMA usage
+=========
+
+The slave DMA usage consists of following steps:
+
+- Allocate a DMA slave channel
+
+- Set slave and controller specific parameters
+
+- Get a descriptor for transaction
+
+- Submit the transaction
+
+- Issue pending requests and wait for callback notification
+
+The details of these operations are:
+
+1. Allocate a DMA slave channel
+
+ Channel allocation is slightly different in the slave DMA context,
+ client drivers typically need a channel from a particular DMA
+ controller only and even in some cases a specific channel is desired.
+ To request a channel dma_request_chan() API is used.
+
+ Interface:
+
+ .. code-block:: c
+
+ struct dma_chan *dma_request_chan(struct device *dev, const char *name);
+
+ Which will find and return the ``name`` DMA channel associated with the 'dev'
+ device. The association is done via DT, ACPI or board file based
+ dma_slave_map matching table.
+
+ A channel allocated via this interface is exclusive to the caller,
+ until dma_release_channel() is called.
+
+2. Set slave and controller specific parameters
+
+ Next step is always to pass some specific information to the DMA
+ driver. Most of the generic information which a slave DMA can use
+ is in struct dma_slave_config. This allows the clients to specify
+ DMA direction, DMA addresses, bus widths, DMA burst lengths etc
+ for the peripheral.
+
+ If some DMA controllers have more parameters to be sent then they
+ should try to embed struct dma_slave_config in their controller
+ specific structure. That gives flexibility to client to pass more
+ parameters, if required.
+
+ Interface:
+
+ .. code-block:: c
+
+ int dmaengine_slave_config(struct dma_chan *chan,
+ struct dma_slave_config *config)
+
+ Please see the dma_slave_config structure definition in dmaengine.h
+ for a detailed explanation of the struct members. Please note
+ that the 'direction' member will be going away as it duplicates the
+ direction given in the prepare call.
+
+3. Get a descriptor for transaction
+
+ For slave usage the various modes of slave transfers supported by the
+ DMA-engine are:
+
+ - slave_sg: DMA a list of scatter gather buffers from/to a peripheral
+
+ - dma_cyclic: Perform a cyclic DMA operation from/to a peripheral till the
+ operation is explicitly stopped.
+
+ - interleaved_dma: This is common to Slave as well as M2M clients. For slave
+ address of devices' fifo could be already known to the driver.
+ Various types of operations could be expressed by setting
+ appropriate values to the 'dma_interleaved_template' members.
+
+ A non-NULL return of this transfer API represents a "descriptor" for
+ the given transaction.
+
+ Interface:
+
+ .. code-block:: c
+
+ struct dma_async_tx_descriptor *dmaengine_prep_slave_sg(
+ struct dma_chan *chan, struct scatterlist *sgl,
+ unsigned int sg_len, enum dma_data_direction direction,
+ unsigned long flags);
+
+ struct dma_async_tx_descriptor *dmaengine_prep_dma_cyclic(
+ struct dma_chan *chan, dma_addr_t buf_addr, size_t buf_len,
+ size_t period_len, enum dma_data_direction direction);
+
+ struct dma_async_tx_descriptor *dmaengine_prep_interleaved_dma(
+ struct dma_chan *chan, struct dma_interleaved_template *xt,
+ unsigned long flags);
+
+ The peripheral driver is expected to have mapped the scatterlist for
+ the DMA operation prior to calling dmaengine_prep_slave_sg(), and must
+ keep the scatterlist mapped until the DMA operation has completed.
+ The scatterlist must be mapped using the DMA struct device.
+ If a mapping needs to be synchronized later, dma_sync_*_for_*() must be
+ called using the DMA struct device, too.
+ So, normal setup should look like this:
+
+ .. code-block:: c
+
+ nr_sg = dma_map_sg(chan->device->dev, sgl, sg_len);
+ if (nr_sg == 0)
+ /* error */
+
+ desc = dmaengine_prep_slave_sg(chan, sgl, nr_sg, direction, flags);
+
+ Once a descriptor has been obtained, the callback information can be
+ added and the descriptor must then be submitted. Some DMA engine
+ drivers may hold a spinlock between a successful preparation and
+ submission so it is important that these two operations are closely
+ paired.
+
+ .. note::
+
+ Although the async_tx API specifies that completion callback
+ routines cannot submit any new operations, this is not the
+ case for slave/cyclic DMA.
+
+ For slave DMA, the subsequent transaction may not be available
+ for submission prior to callback function being invoked, so
+ slave DMA callbacks are permitted to prepare and submit a new
+ transaction.
+
+ For cyclic DMA, a callback function may wish to terminate the
+ DMA via dmaengine_terminate_async().
+
+ Therefore, it is important that DMA engine drivers drop any
+ locks before calling the callback function which may cause a
+ deadlock.
+
+ Note that callbacks will always be invoked from the DMA
+ engines tasklet, never from interrupt context.
+
+4. Submit the transaction
+
+ Once the descriptor has been prepared and the callback information
+ added, it must be placed on the DMA engine drivers pending queue.
+
+ Interface:
+
+ .. code-block:: c
+
+ dma_cookie_t dmaengine_submit(struct dma_async_tx_descriptor *desc)
+
+ This returns a cookie can be used to check the progress of DMA engine
+ activity via other DMA engine calls not covered in this document.
+
+ dmaengine_submit() will not start the DMA operation, it merely adds
+ it to the pending queue. For this, see step 5, dma_async_issue_pending.
+
+5. Issue pending DMA requests and wait for callback notification
+
+ The transactions in the pending queue can be activated by calling the
+ issue_pending API. If channel is idle then the first transaction in
+ queue is started and subsequent ones queued up.
+
+ On completion of each DMA operation, the next in queue is started and
+ a tasklet triggered. The tasklet will then call the client driver
+ completion callback routine for notification, if set.
+
+ Interface:
+
+ .. code-block:: c
+
+ void dma_async_issue_pending(struct dma_chan *chan);
+
+Further APIs:
+------------
+
+1. Terminate APIs
+
+ .. code-block:: c
+
+ int dmaengine_terminate_sync(struct dma_chan *chan)
+ int dmaengine_terminate_async(struct dma_chan *chan)
+ int dmaengine_terminate_all(struct dma_chan *chan) /* DEPRECATED */
+
+ This causes all activity for the DMA channel to be stopped, and may
+ discard data in the DMA FIFO which hasn't been fully transferred.
+ No callback functions will be called for any incomplete transfers.
+
+ Two variants of this function are available.
+
+ dmaengine_terminate_async() might not wait until the DMA has been fully
+ stopped or until any running complete callbacks have finished. But it is
+ possible to call dmaengine_terminate_async() from atomic context or from
+ within a complete callback. dmaengine_synchronize() must be called before it
+ is safe to free the memory accessed by the DMA transfer or free resources
+ accessed from within the complete callback.
+
+ dmaengine_terminate_sync() will wait for the transfer and any running
+ complete callbacks to finish before it returns. But the function must not be
+ called from atomic context or from within a complete callback.
+
+ dmaengine_terminate_all() is deprecated and should not be used in new code.
+
+2. Pause API
+
+ .. code-block:: c
+
+ int dmaengine_pause(struct dma_chan *chan)
+
+ This pauses activity on the DMA channel without data loss.
+
+3. Resume API
+
+ .. code-block:: c
+
+ int dmaengine_resume(struct dma_chan *chan)
+
+ Resume a previously paused DMA channel. It is invalid to resume a
+ channel which is not currently paused.
+
+4. Check Txn complete
+
+ .. code-block:: c
+
+ enum dma_status dma_async_is_tx_complete(struct dma_chan *chan,
+ dma_cookie_t cookie, dma_cookie_t *last, dma_cookie_t *used)
+
+ This can be used to check the status of the channel. Please see
+ the documentation in include/linux/dmaengine.h for a more complete
+ description of this API.
+
+ This can be used in conjunction with dma_async_is_complete() and
+ the cookie returned from dmaengine_submit() to check for
+ completion of a specific DMA transaction.
+
+ .. note::
+
+ Not all DMA engine drivers can return reliable information for
+ a running DMA channel. It is recommended that DMA engine users
+ pause or stop (via dmaengine_terminate_all()) the channel before
+ using this API.
+
+5. Synchronize termination API
+
+ .. code-block:: c
+
+ void dmaengine_synchronize(struct dma_chan *chan)
+
+ Synchronize the termination of the DMA channel to the current context.
+
+ This function should be used after dmaengine_terminate_async() to synchronize
+ the termination of the DMA channel to the current context. The function will
+ wait for the transfer and any running complete callbacks to finish before it
+ returns.
+
+ If dmaengine_terminate_async() is used to stop the DMA channel this function
+ must be called before it is safe to free memory accessed by previously
+ submitted descriptors or to free any resources accessed within the complete
+ callback of previously submitted descriptors.
+
+ The behavior of this function is undefined if dma_async_issue_pending() has
+ been called between dmaengine_terminate_async() and this function.

+==================================
+DMAengine controller documentation
+==================================
+
+Hardware Introduction
+=====================
+
+Most of the Slave DMA controllers have the same general principles of
+operations.
+
+They have a given number of channels to use for the DMA transfers, and
+a given number of requests lines.
+
+Requests and channels are pretty much orthogonal. Channels can be used
+to serve several to any requests. To simplify, channels are the
+entities that will be doing the copy, and requests what endpoints are
+involved.
+
+The request lines actually correspond to physical lines going from the
+DMA-eligible devices to the controller itself. Whenever the device
+will want to start a transfer, it will assert a DMA request (DRQ) by
+asserting that request line.
+
+A very simple DMA controller would only take into account a single
+parameter: the transfer size. At each clock cycle, it would transfer a
+byte of data from one buffer to another, until the transfer size has
+been reached.
+
+That wouldn't work well in the real world, since slave devices might
+require a specific number of bits to be transferred in a single
+cycle. For example, we may want to transfer as much data as the
+physical bus allows to maximize performances when doing a simple
+memory copy operation, but our audio device could have a narrower FIFO
+that requires data to be written exactly 16 or 24 bits at a time. This
+is why most if not all of the DMA controllers can adjust this, using a
+parameter called the transfer width.
+
+Moreover, some DMA controllers, whenever the RAM is used as a source
+or destination, can group the reads or writes in memory into a buffer,
+so instead of having a lot of small memory accesses, which is not
+really efficient, you'll get several bigger transfers. This is done
+using a parameter called the burst size, that defines how many single
+reads/writes it's allowed to do without the controller splitting the
+transfer into smaller sub-transfers.
+
+Our theoretical DMA controller would then only be able to do transfers
+that involve a single contiguous block of data. However, some of the
+transfers we usually have are not, and want to copy data from
+non-contiguous buffers to a contiguous buffer, which is called
+scatter-gather.
+
+DMAEngine, at least for mem2dev transfers, require support for
+scatter-gather. So we're left with two cases here: either we have a
+quite simple DMA controller that doesn't support it, and we'll have to
+implement it in software, or we have a more advanced DMA controller,
+that implements in hardware scatter-gather.
+
+The latter are usually programmed using a collection of chunks to
+transfer, and whenever the transfer is started, the controller will go
+over that collection, doing whatever we programmed there.
+
+This collection is usually either a table or a linked list. You will
+then push either the address of the table and its number of elements,
+or the first item of the list to one channel of the DMA controller,
+and whenever a DRQ will be asserted, it will go through the collection
+to know where to fetch the data from.
+
+Either way, the format of this collection is completely dependent on
+your hardware. Each DMA controller will require a different structure,
+but all of them will require, for every chunk, at least the source and
+destination addresses, whether it should increment these addresses or
+not and the three parameters we saw earlier: the burst size, the
+transfer width and the transfer size.
+
+The one last thing is that usually, slave devices won't issue DRQ by
+default, and you have to enable this in your slave device driver first
+whenever you're willing to use DMA.
+
+These were just the general memory-to-memory (also called mem2mem) or
+memory-to-device (mem2dev) kind of transfers. Most devices often
+support other kind of transfers or memory operations that dmaengine
+support and will be detailed later in this document.
+
+DMA Support in Linux
+====================
+
+Historically, DMA controller drivers have been implemented using the
+async TX API, to offload operations such as memory copy, XOR,
+cryptography, etc., basically any memory to memory operation.
+
+Over time, the need for memory to device transfers arose, and
+dmaengine was extended. Nowadays, the async TX API is written as a
+layer on top of dmaengine, and acts as a client. Still, dmaengine
+accommodates that API in some cases, and made some design choices to
+ensure that it stayed compatible.
+
+For more information on the Async TX API, please look the relevant
+documentation file in Documentation/crypto/async-tx-api.txt.
+
+DMAEngine APIs
+==============
+
+``struct dma_device`` Initialization
+------------------------------------
+
+Just like any other kernel framework, the whole DMAEngine registration
+relies on the driver filling a structure and registering against the
+framework. In our case, that structure is dma_device.
+
+The first thing you need to do in your driver is to allocate this
+structure. Any of the usual memory allocators will do, but you'll also
+need to initialize a few fields in there:
+
+- channels: should be initialized as a list using the
+ INIT_LIST_HEAD macro for example
+
+- src_addr_widths:
+ should contain a bitmask of the supported source transfer width
+
+- dst_addr_widths:
+ should contain a bitmask of the supported destination transfer width
+
+- directions:
+ should contain a bitmask of the supported slave directions
+ (i.e. excluding mem2mem transfers)
+
+- residue_granularity:
+
+ - Granularity of the transfer residue reported to dma_set_residue.
+ This can be either:
+
+ - Descriptor
+
+ - Your device doesn't support any kind of residue
+ reporting. The framework will only know that a particular
+ transaction descriptor is done.
+
+ - Segment
+
+ - Your device is able to report which chunks have been transferred
+
+ - Burst
+
+ - Your device is able to report which burst have been transferred
+
+ - dev: should hold the pointer to the ``struct device`` associated
+ to your current driver instance.
+
+Supported transaction types
+---------------------------
+
+The next thing you need is to set which transaction types your device
+(and driver) supports.
+
+Our ``dma_device structure`` has a field called cap_mask that holds the
+various types of transaction supported, and you need to modify this
+mask using the dma_cap_set function, with various flags depending on
+transaction types you support as an argument.
+
+All those capabilities are defined in the ``dma_transaction_type enum``,
+in ``include/linux/dmaengine.h``
+
+Currently, the types available are:
+
+- DMA_MEMCPY
+
+ - The device is able to do memory to memory copies
+
+- DMA_XOR
+
+ - The device is able to perform XOR operations on memory areas
+
+ - Used to accelerate XOR intensive tasks, such as RAID5
+
+- DMA_XOR_VAL
+
+ - The device is able to perform parity check using the XOR
+ algorithm against a memory buffer.
+
+- DMA_PQ
+
+ - The device is able to perform RAID6 P+Q computations, P being a
+ simple XOR, and Q being a Reed-Solomon algorithm.
+
+- DMA_PQ_VAL
+
+ - The device is able to perform parity check using RAID6 P+Q
+ algorithm against a memory buffer.
+
+- DMA_INTERRUPT
+
+ - The device is able to trigger a dummy transfer that will
+ generate periodic interrupts
+
+ - Used by the client drivers to register a callback that will be
+ called on a regular basis through the DMA controller interrupt
+
+- DMA_PRIVATE
+
+ - The devices only supports slave transfers, and as such isn't
+ available for async transfers.
+
+- DMA_ASYNC_TX
+
+ - Must not be set by the device, and will be set by the framework
+ if needed
+
+ - TODO: What is it about?
+
+- DMA_SLAVE
+
+ - The device can handle device to memory transfers, including
+ scatter-gather transfers.
+
+ - While in the mem2mem case we were having two distinct types to
+ deal with a single chunk to copy or a collection of them, here,
+ we just have a single transaction type that is supposed to
+ handle both.
+
+ - If you want to transfer a single contiguous memory buffer,
+ simply build a scatter list with only one item.
+
+- DMA_CYCLIC
+
+ - The device can handle cyclic transfers.
+
+ - A cyclic transfer is a transfer where the chunk collection will
+ loop over itself, with the last item pointing to the first.
+
+ - It's usually used for audio transfers, where you want to operate
+ on a single ring buffer that you will fill with your audio data.
+
+- DMA_INTERLEAVE
+
+ - The device supports interleaved transfer.
+
+ - These transfers can transfer data from a non-contiguous buffer
+ to a non-contiguous buffer, opposed to DMA_SLAVE that can
+ transfer data from a non-contiguous data set to a continuous
+ destination buffer.
+
+ - It's usually used for 2d content transfers, in which case you
+ want to transfer a portion of uncompressed data directly to the
+ display to print it
+
+These various types will also affect how the source and destination
+addresses change over time.
+
+Addresses pointing to RAM are typically incremented (or decremented)
+after each transfer. In case of a ring buffer, they may loop
+(DMA_CYCLIC). Addresses pointing to a device's register (e.g. a FIFO)
+are typically fixed.
+
+Device operations
+-----------------
+
+Our dma_device structure also requires a few function pointers in
+order to implement the actual logic, now that we described what
+operations we were able to perform.
+
+The functions that we have to fill in there, and hence have to
+implement, obviously depend on the transaction types you reported as
+supported.
+
+- ``device_alloc_chan_resources``
+
+- ``device_free_chan_resources``
+
+ - These functions will be called whenever a driver will call
+ ``dma_request_channel`` or ``dma_release_channel`` for the first/last
+ time on the channel associated to that driver.
+
+ - They are in charge of allocating/freeing all the needed
+ resources in order for that channel to be useful for your driver.
+
+ - These functions can sleep.
+
+- ``device_prep_dma_*``
+
+ - These functions are matching the capabilities you registered
+ previously.
+
+ - These functions all take the buffer or the scatterlist relevant
+ for the transfer being prepared, and should create a hardware
+ descriptor or a list of hardware descriptors from it
+
+ - These functions can be called from an interrupt context
+
+ - Any allocation you might do should be using the GFP_NOWAIT
+ flag, in order not to potentially sleep, but without depleting
+ the emergency pool either.
+
+ - Drivers should try to pre-allocate any memory they might need
+ during the transfer setup at probe time to avoid putting to
+ much pressure on the nowait allocator.
+
+ - It should return a unique instance of the
+ ``dma_async_tx_descriptor structure``, that further represents this
+ particular transfer.
+
+ - This structure can be initialized using the function
+ ``dma_async_tx_descriptor_init``.
+
+ - You'll also need to set two fields in this structure:
+
+ - flags:
+ TODO: Can it be modified by the driver itself, or
+ should it be always the flags passed in the arguments
+
+ - tx_submit: A pointer to a function you have to implement,
+ that is supposed to push the current transaction descriptor to a
+ pending queue, waiting for issue_pending to be called.
+
+ - In this structure the function pointer callback_result can be
+ initialized in order for the submitter to be notified that a
+ transaction has completed. In the earlier code the function pointer
+ callback has been used. However it does not provide any status to the
+ transaction and will be deprecated. The result structure defined as
+ ``dmaengine_result`` that is passed in to callback_result
+ has two fields:
+
+ - result: This provides the transfer result defined by
+ ``dmaengine_tx_result``. Either success or some error condition.
+
+ - residue: Provides the residue bytes of the transfer for those that
+ support residue.
+
+- ``device_issue_pending``
+
+ - Takes the first transaction descriptor in the pending queue,
+ and starts the transfer. Whenever that transfer is done, it
+ should move to the next transaction in the list.
+
+ - This function can be called in an interrupt context
+
+- ``device_tx_status``
+
+ - Should report the bytes left to go over on the given channel
+
+ - Should only care about the transaction descriptor passed as
+ argument, not the currently active one on a given channel
+
+ - The tx_state argument might be NULL
+
+ - Should use dma_set_residue to report it
+
+ - In the case of a cyclic transfer, it should only take into
+ account the current period.
+
+ - This function can be called in an interrupt context.
+
+- device_config
+
+ - Reconfigures the channel with the configuration given as argument
+
+ - This command should NOT perform synchronously, or on any
+ currently queued transfers, but only on subsequent ones
+
+ - In this case, the function will receive a ``dma_slave_config``
+ structure pointer as an argument, that will detail which
+ configuration to use.
+
+ - Even though that structure contains a direction field, this
+ field is deprecated in favor of the direction argument given to
+ the prep_* functions
+
+ - This call is mandatory for slave operations only. This should NOT be
+ set or expected to be set for memcpy operations.
+ If a driver support both, it should use this call for slave
+ operations only and not for memcpy ones.
+
+- device_pause
+
+ - Pauses a transfer on the channel
+
+ - This command should operate synchronously on the channel,
+ pausing right away the work of the given channel
+
+- device_resume
+
+ - Resumes a transfer on the channel
+
+ - This command should operate synchronously on the channel,
+ resuming right away the work of the given channel
+
+- device_terminate_all
+
+ - Aborts all the pending and ongoing transfers on the channel
+
+ - For aborted transfers the complete callback should not be called
+
+ - Can be called from atomic context or from within a complete
+ callback of a descriptor. Must not sleep. Drivers must be able
+ to handle this correctly.
+
+ - Termination may be asynchronous. The driver does not have to
+ wait until the currently active transfer has completely stopped.
+ See device_synchronize.
+

+
+- This can be acked by invoking async_tx_ack()
+

+
+DMA_CTRL_REUSE
+
+- If set, the descriptor can be reused after being completed. It should
+ not be freed by provider if this flag is set.
+
+- The descriptor should be prepared for reuse by invoking
+ ``dmaengine_desc_set_reuse()`` which will set DMA_CTRL_REUSE.
+
+- ``dmaengine_desc_set_reuse()`` will succeed only when channel support
+ reusable descriptor as exhibited by capabilities
+
+- As a consequence, if a device driver wants to skip the
+ ``dma_map_sg()`` and ``dma_unmap_sg()`` in between 2 transfers,
+ because the DMA'd data wasn't used, it can resubmit the transfer right after
+ its completion.
+
+- Descriptor can be freed in few ways
+
+ - Clearing DMA_CTRL_REUSE by invoking
+ ``dmaengine_desc_clear_reuse()`` and submitting for last txn
+
+ - Explicitly invoking ``dmaengine_desc_free()``, this can succeed only
+ when DMA_CTRL_REUSE is already set
+
+ - Terminating the channel
+
+- DMA_PREP_CMD
+
+ - If set, the client driver tells DMA controller that passed data in DMA
+ API is command data.
+
+ - Interpretation of command data is DMA controller specific. It can be
+ used for issuing commands to other peripherals/register reads/register
+ writes for which the descriptor should be in different format from
+ normal data descriptors.
+
+General Design Notes
+====================
+
+Most of the DMAEngine drivers you'll see are based on a similar design
+that handles the end of transfer interrupts in the handler, but defer
+most work to a tasklet, including the start of a new transfer whenever
+the previous transfer ended.
+
+This is a rather inefficient design though, because the inter-transfer
+latency will be not only the interrupt latency, but also the
+scheduling latency of the tasklet, which will leave the channel idle
+in between, which will slow down the global transfer rate.
+
+You should avoid this kind of practice, and instead of electing a new
+transfer in your tasklet, move that part to the interrupt handler in
+order to have a shorter idle window (that we can't really avoid
+anyway).
+
+Glossary
+========
+
+- Burst: A number of consecutive read or write operations that
+ can be queued to buffers before being flushed to memory.
+
+- Chunk: A contiguous collection of bursts
+
+- Transfer: A collection of chunks (be it contiguous or not)

+==============================
+PXA/MMP - DMA Slave controller
+==============================
+
+Constraints
+===========
+
+a) Transfers hot queuing
+A driver submitting a transfer and issuing it should be granted the transfer
+is queued even on a running DMA channel.
+This implies that the queuing doesn't wait for the previous transfer end,
+and that the descriptor chaining is not only done in the irq/tasklet code
+triggered by the end of the transfer.
+A transfer which is submitted and issued on a phy doesn't wait for a phy to
+stop and restart, but is submitted on a "running channel". The other
+drivers, especially mmp_pdma waited for the phy to stop before relaunching
+a new transfer.
+
+b) All transfers having asked for confirmation should be signaled
+Any issued transfer with DMA_PREP_INTERRUPT should trigger a callback call.
+This implies that even if an irq/tasklet is triggered by end of tx1, but
+at the time of irq/dma tx2 is already finished, tx1->complete() and
+tx2->complete() should be called.
+
+c) Channel running state
+A driver should be able to query if a channel is running or not. For the
+multimedia case, such as video capture, if a transfer is submitted and then
+a check of the DMA channel reports a "stopped channel", the transfer should
+not be issued until the next "start of frame interrupt", hence the need to
+know if a channel is in running or stopped state.
+
+d) Bandwidth guarantee
+The PXA architecture has 4 levels of DMAs priorities : high, normal, low.
+The high priorities get twice as much bandwidth as the normal, which get twice
+as much as the low priorities.
+A driver should be able to request a priority, especially the real-time
+ones such as pxa_camera with (big) throughputs.
+
+Design
+======
+a) Virtual channels
+Same concept as in sa11x0 driver, ie. a driver was assigned a "virtual
+channel" linked to the requestor line, and the physical DMA channel is
+assigned on the fly when the transfer is issued.
+
+b) Transfer anatomy for a scatter-gather transfer
+
+::
+
+ +------------+-----+---------------+----------------+-----------------+
+ | desc-sg[0] | ... | desc-sg[last] | status updater | finisher/linker |
+ +------------+-----+---------------+----------------+-----------------+
+
+This structure is pointed by dma->sg_cpu.
+The descriptors are used as follows :
+
+ - desc-sg[i]: i-th descriptor, transferring the i-th sg
+ element to the video buffer scatter gather
+
+ - status updater
+ Transfers a single u32 to a well known dma coherent memory to leave
+ a trace that this transfer is done. The "well known" is unique per
+ physical channel, meaning that a read of this value will tell which
+ is the last finished transfer at that point in time.
+
+ - finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
+
+ - linker: has ddadr= desc-sg[0] of next transfer, dcmd=0
+
+c) Transfers hot-chaining
+Suppose the running chain is:
+
+::
+
+ Buffer 1 Buffer 2
+ +---------+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+---+
+ | |
+ +----+
+
+After a call to dmaengine_submit(b3), the chain will look like:
+
+::
+
+ Buffer 1 Buffer 2 Buffer 3
+ +---------+----+---+ +----+----+----+---+ +----+----+----+---+
+ | d0 | .. | dN | l | | d0 | .. | dN | l | | d0 | .. | dN | f |
+ +---------+----+-|-+ ^----+----+----+-|-+ ^----+----+----+---+
+ | | | |
+ +----+ +----+
+ new_link
+
+If while new_link was created the DMA channel stopped, it is _not_
+restarted. Hot-chaining doesn't break the assumption that
+dma_async_issue_pending() is to be used to ensure the transfer is actually started.
+
+One exception to this rule :
+
+- if Buffer1 and Buffer2 had all their addresses 8 bytes aligned
+
+- and if Buffer3 has at least one address not 4 bytes aligned
+
+- then hot-chaining cannot happen, as the channel must be stopped, the
+ "align bit" must be set, and the channel restarted As a consequence,
+ such a transfer tx_submit() will be queued on the submitted queue, and
+ this specific case if the DMA is already running in aligned mode.
+
+d) Transfers completion updater
+Each time a transfer is completed on a channel, an interrupt might be
+generated or not, up to the client's request. But in each case, the last
+descriptor of a transfer, the "status updater", will write the latest
+transfer being completed into the physical channel's completion mark.
+
+This will speed up residue calculation, for large transfers such as video
+buffers which hold around 6k descriptors or more. This also allows without
+any lock to find out what is the latest completed transfer in a running
+DMA chain.
+
+e) Transfers completion, irq and tasklet
+When a transfer flagged as "DMA_PREP_INTERRUPT" is finished, the dma irq
+is raised. Upon this interrupt, a tasklet is scheduled for the physical
+channel.
+
+The tasklet is responsible for :
+
+- reading the physical channel last updater mark
+
+- calling all the transfer callbacks of finished transfers, based on
+ that mark, and each transfer flags.
+
+If a transfer is completed while this handling is done, a dma irq will
+be raised, and the tasklet will be scheduled once again, having a new
+updater mark.
+
+f) Residue
+Residue granularity will be descriptor based. The issued but not completed
+transfers will be scanned for all of their descriptors against the
+currently running descriptor.
+
+g) Most complicated case of driver's tx queues
+The most tricky situation is when :
+
+ - there are not "acked" transfers (tx0)
+
+ - a driver submitted an aligned tx1, not chained
+
+ - a driver submitted an aligned tx2 => tx2 is cold chained to tx1
+
+ - a driver issued tx1+tx2 => channel is running in aligned mode
+
+ - a driver submitted an aligned tx3 => tx3 is hot-chained
+
+ - a driver submitted an unaligned tx4 => tx4 is put in submitted queue,
+ not chained
+
+ - a driver issued tx4 => tx4 is put in issued queue, not chained
+
+ - a driver submitted an aligned tx5 => tx5 is put in submitted queue, not
+ chained
+
+ - a driver submitted an aligned tx6 => tx6 is put in submitted queue,
+ cold chained to tx5
+
+ This translates into (after tx4 is issued) :
+
+ - issued queue
+
+ ::
+
+ +-----+ +-----+ +-----+ +-----+
+ | tx1 | | tx2 | | tx3 | | tx4 |
+ +---|-+ ^---|-+ ^-----+ +-----+
+ | | | |
+ +---+ +---+
+ - submitted queue
+ +-----+ +-----+
+ | tx5 | | tx6 |
+ +---|-+ ^-----+
+ | |
+ +---+
+
+- completed queue : empty
+
+- allocated queue : tx0
+
+It should be noted that after tx3 is completed, the channel is stopped, and
+restarted in "unaligned mode" to handle tx4.

+Memory Mapped cramfs image
+--------------------------
+
+The CRAMFS_MTD Kconfig option adds support for loading data directly from
+a physical linear memory range (usually non volatile memory like Flash)
+instead of going through the block device layer. This saves some memory
+since no intermediate buffering is necessary to hold the data before
+decompressing.
+
+And when data blocks are kept uncompressed and properly aligned, they will
+automatically be mapped directly into user space whenever possible providing
+eXecute-In-Place (XIP) from ROM of read-only segments. Data segments mapped
+read-write (hence they have to be copied to RAM) may still be compressed in
+the cramfs image in the same file along with non compressed read-only
+segments. Both MMU and no-MMU systems are supported. This is particularly
+handy for tiny embedded systems with very tight memory constraints.
+
+The location of the cramfs image in memory is system dependent. You must
+know the proper physical address where the cramfs image is located and
+configure an MTD device for it. Also, that MTD device must be supported
+by a map driver that implements the "point" method. Examples of such
+MTD drivers are cfi_cmdset_0001 (Intel/Sharp CFI flash) or physmap
+(Flash device in physical memory map). MTD partitions based on such devices
+are fine too. Then that device should be specified with the "mtd:" prefix
+as the mount device argument. For example, to mount the MTD device named
+"fs_partition" on the /mnt directory:
+
+$ mount -t cramfs mtd:fs_partition /mnt

+=====================================
+Filesystem-level encryption (fscrypt)
+=====================================
+
+Introduction
+============
+
+fscrypt is a library which filesystems can hook into to support
+transparent encryption of files and directories.
+
+Note: "fscrypt" in this document refers to the kernel-level portion,
+implemented in ``fs/crypto/``, as opposed to the userspace tool
+`fscrypt <https://github.com/google/fscrypt>`_. This document only
+covers the kernel-level portion. For command-line examples of how to
+use encryption, see the documentation for the userspace tool `fscrypt
+<https://github.com/google/fscrypt>`_. Also, it is recommended to use
+the fscrypt userspace tool, or other existing userspace tools such as
+`fscryptctl <https://github.com/google/fscryptctl>`_ or `Android's key
+management system
+<https://source.android.com/security/encryption/file-based>`_, over
+using the kernel's API directly. Using existing tools reduces the
+chance of introducing your own security bugs. (Nevertheless, for
+completeness this documentation covers the kernel's API anyway.)
+
+Unlike dm-crypt, fscrypt operates at the filesystem level rather than
+at the block device level. This allows it to encrypt different files
+with different keys and to have unencrypted files on the same
+filesystem. This is useful for multi-user systems where each user's
+data-at-rest needs to be cryptographically isolated from the others.
+However, except for filenames, fscrypt does not encrypt filesystem
+metadata.
+
+Unlike eCryptfs, which is a stacked filesystem, fscrypt is integrated
+directly into supported filesystems --- currently ext4, F2FS, and
+UBIFS. This allows encrypted files to be read and written without
+caching both the decrypted and encrypted pages in the pagecache,
+thereby nearly halving the memory used and bringing it in line with
+unencrypted files. Similarly, half as many dentries and inodes are
+needed. eCryptfs also limits encrypted filenames to 143 bytes,
+causing application compatibility issues; fscrypt allows the full 255
+bytes (NAME_MAX). Finally, unlike eCryptfs, the fscrypt API can be
+used by unprivileged users, with no need to mount anything.
+
+fscrypt does not support encrypting files in-place. Instead, it
+supports marking an empty directory as encrypted. Then, after
+userspace provides the key, all regular files, directories, and
+symbolic links created in that directory tree are transparently
+encrypted.
+
+Threat model
+============
+
+Offline attacks
+---------------
+
+Provided that userspace chooses a strong encryption key, fscrypt
+protects the confidentiality of file contents and filenames in the
+event of a single point-in-time permanent offline compromise of the
+block device content. fscrypt does not protect the confidentiality of
+non-filename metadata, e.g. file sizes, file permissions, file
+timestamps, and extended attributes. Also, the existence and location
+of holes (unallocated blocks which logically contain all zeroes) in
+files is not protected.
+
+fscrypt is not guaranteed to protect confidentiality or authenticity
+if an attacker is able to manipulate the filesystem offline prior to
+an authorized user later accessing the filesystem.
+
+Online attacks
+--------------
+
+fscrypt (and storage encryption in general) can only provide limited
+protection, if any at all, against online attacks. In detail:
+
+fscrypt is only resistant to side-channel attacks, such as timing or
+electromagnetic attacks, to the extent that the underlying Linux
+Cryptographic API algorithms are. If a vulnerable algorithm is used,
+such as a table-based implementation of AES, it may be possible for an
+attacker to mount a side channel attack against the online system.
+Side channel attacks may also be mounted against applications
+consuming decrypted data.
+
+After an encryption key has been provided, fscrypt is not designed to
+hide the plaintext file contents or filenames from other users on the
+same system, regardless of the visibility of the keyring key.
+Instead, existing access control mechanisms such as file mode bits,
+POSIX ACLs, LSMs, or mount namespaces should be used for this purpose.
+Also note that as long as the encryption keys are *anywhere* in
+memory, an online attacker can necessarily compromise them by mounting
+a physical attack or by exploiting any kernel security vulnerability
+which provides an arbitrary memory read primitive.
+
+While it is ostensibly possible to "evict" keys from the system,
+recently accessed encrypted files will remain accessible at least
+until the filesystem is unmounted or the VFS caches are dropped, e.g.
+using ``echo 2 > /proc/sys/vm/drop_caches``. Even after that, if the
+RAM is compromised before being powered off, it will likely still be
+possible to recover portions of the plaintext file contents, if not
+some of the encryption keys as well. (Since Linux v4.12, all
+in-kernel keys related to fscrypt are sanitized before being freed.
+However, userspace would need to do its part as well.)
+
+Currently, fscrypt does not prevent a user from maliciously providing
+an incorrect key for another user's existing encrypted files. A
+protection against this is planned.
+
+Key hierarchy
+=============
+
+Master Keys
+-----------
+
+Each encrypted directory tree is protected by a *master key*. Master
+keys can be up to 64 bytes long, and must be at least as long as the
+greater of the key length needed by the contents and filenames
+encryption modes being used. For example, if AES-256-XTS is used for
+contents encryption, the master key must be 64 bytes (512 bits). Note
+that the XTS mode is defined to require a key twice as long as that
+required by the underlying block cipher.
+
+To "unlock" an encrypted directory tree, userspace must provide the
+appropriate master key. There can be any number of master keys, each
+of which protects any number of directory trees on any number of
+filesystems.
+
+Userspace should generate master keys either using a cryptographically
+secure random number generator, or by using a KDF (Key Derivation
+Function). Note that whenever a KDF is used to "stretch" a
+lower-entropy secret such as a passphrase, it is critical that a KDF
+designed for this purpose be used, such as scrypt, PBKDF2, or Argon2.
+
+Per-file keys
+-------------
+
+Master keys are not used to encrypt file contents or names directly.
+Instead, a unique key is derived for each encrypted file, including
+each regular file, directory, and symbolic link. This has several
+advantages:
+
+- In cryptosystems, the same key material should never be used for
+ different purposes. Using the master key as both an XTS key for
+ contents encryption and as a CTS-CBC key for filenames encryption
+ would violate this rule.
+- Per-file keys simplify the choice of IVs (Initialization Vectors)
+ for contents encryption. Without per-file keys, to ensure IV
+ uniqueness both the inode and logical block number would need to be
+ encoded in the IVs. This would make it impossible to renumber
+ inodes, which e.g. ``resize2fs`` can do when resizing an ext4
+ filesystem. With per-file keys, it is sufficient to encode just the
+ logical block number in the IVs.
+- Per-file keys strengthen the encryption of filenames, where IVs are
+ reused out of necessity. With a unique key per directory, IV reuse
+ is limited to within a single directory.
+- Per-file keys allow individual files to be securely erased simply by
+ securely erasing their keys. (Not yet implemented.)
+
+A KDF (Key Derivation Function) is used to derive per-file keys from
+the master key. This is done instead of wrapping a randomly-generated
+key for each file because it reduces the size of the encryption xattr,
+which for some filesystems makes the xattr more likely to fit in-line
+in the filesystem's inode table. With a KDF, only a 16-byte nonce is
+required --- long enough to make key reuse extremely unlikely. A
+wrapped key, on the other hand, would need to be up to 64 bytes ---
+the length of an AES-256-XTS key. Furthermore, currently there is no
+requirement to support unlocking a file with multiple alternative
+master keys or to support rotating master keys. Instead, the master
+keys may be wrapped in userspace, e.g. as done by the `fscrypt
+<https://github.com/google/fscrypt>`_ tool.
+
+The current KDF encrypts the master key using the 16-byte nonce as an
+AES-128-ECB key. The output is used as the derived key. If the
+output is longer than needed, then it is truncated to the needed
+length. Truncation is the norm for directories and symlinks, since
+those use the CTS-CBC encryption mode which requires a key half as
+long as that required by the XTS encryption mode.
+
+Note: this KDF meets the primary security requirement, which is to
+produce unique derived keys that preserve the entropy of the master
+key, assuming that the master key is already a good pseudorandom key.
+However, it is nonstandard and has some problems such as being
+reversible, so it is generally considered to be a mistake! It may be
+replaced with HKDF or another more standard KDF in the future.
+
+Encryption modes and usage
+==========================
+
+fscrypt allows one encryption mode to be specified for file contents
+and one encryption mode to be specified for filenames. Different
+directory trees are permitted to use different encryption modes.
+Currently, the following pairs of encryption modes are supported:
+
+- AES-256-XTS for contents and AES-256-CTS-CBC for filenames
+- AES-128-CBC for contents and AES-128-CTS-CBC for filenames
+
+It is strongly recommended to use AES-256-XTS for contents encryption.
+AES-128-CBC was added only for low-powered embedded devices with
+crypto accelerators such as CAAM or CESA that do not support XTS.
+
+New encryption modes can be added relatively easily, without changes
+to individual filesystems. However, authenticated encryption (AE)
+modes are not currently supported because of the difficulty of dealing
+with ciphertext expansion.
+
+For file contents, each filesystem block is encrypted independently.
+Currently, only the case where the filesystem block size is equal to
+the system's page size (usually 4096 bytes) is supported. With the
+XTS mode of operation (recommended), the logical block number within
+the file is used as the IV. With the CBC mode of operation (not
+recommended), ESSIV is used; specifically, the IV for CBC is the
+logical block number encrypted with AES-256, where the AES-256 key is
+the SHA-256 hash of the inode's data encryption key.
+
+For filenames, the full filename is encrypted at once. Because of the
+requirements to retain support for efficient directory lookups and
+filenames of up to 255 bytes, a constant initialization vector (IV) is
+used. However, each encrypted directory uses a unique key, which
+limits IV reuse to within a single directory. Note that IV reuse in
+the context of CTS-CBC encryption means that when the original
+filenames share a common prefix at least as long as the cipher block
+size (16 bytes for AES), the corresponding encrypted filenames will
+also share a common prefix. This is undesirable; it may be fixed in
+the future by switching to an encryption mode that is a strong
+pseudorandom permutation on arbitrary-length messages, e.g. the HEH
+(Hash-Encrypt-Hash) mode.
+
+Since filenames are encrypted with the CTS-CBC mode of operation, the
+plaintext and ciphertext filenames need not be multiples of the AES
+block size, i.e. 16 bytes. However, the minimum size that can be
+encrypted is 16 bytes, so shorter filenames are NUL-padded to 16 bytes
+before being encrypted. In addition, to reduce leakage of filename
+lengths via their ciphertexts, all filenames are NUL-padded to the
+next 4, 8, 16, or 32-byte boundary (configurable). 32 is recommended
+since this provides the best confidentiality, at the cost of making
+directory entries consume slightly more space. Note that since NUL
+(``\0``) is not otherwise a valid character in filenames, the padding
+will never produce duplicate plaintexts.
+
+Symbolic link targets are considered a type of filename and are
+encrypted in the same way as filenames in directory entries. Each
+symlink also uses a unique key; hence, the hardcoded IV is not a
+problem for symlinks.
+
+User API
+========
+
+Setting an encryption policy
+----------------------------
+
+The FS_IOC_SET_ENCRYPTION_POLICY ioctl sets an encryption policy on an
+empty directory or verifies that a directory or regular file already
+has the specified encryption policy. It takes in a pointer to a
+:c:type:`struct fscrypt_policy`, defined as follows::
+
+ #define FS_KEY_DESCRIPTOR_SIZE 8
+
+ struct fscrypt_policy {
+ __u8 version;
+ __u8 contents_encryption_mode;
+ __u8 filenames_encryption_mode;
+ __u8 flags;
+ __u8 master_key_descriptor[FS_KEY_DESCRIPTOR_SIZE];
+ };
+
+This structure must be initialized as follows:
+
+- ``version`` must be 0.
+
+- ``contents_encryption_mode`` and ``filenames_encryption_mode`` must
+ be set to constants from ``<linux/fs.h>`` which identify the
+ encryption modes to use. If unsure, use
+ FS_ENCRYPTION_MODE_AES_256_XTS (1) for ``contents_encryption_mode``
+ and FS_ENCRYPTION_MODE_AES_256_CTS (4) for
+ ``filenames_encryption_mode``.
+
+- ``flags`` must be set to a value from ``<linux/fs.h>`` which
+ identifies the amount of NUL-padding to use when encrypting
+ filenames. If unsure, use FS_POLICY_FLAGS_PAD_32 (0x3).
+
+- ``master_key_descriptor`` specifies how to find the master key in
+ the keyring; see `Adding keys`_. It is up to userspace to choose a
+ unique ``master_key_descriptor`` for each master key. The e4crypt
+ and fscrypt tools use the first 8 bytes of
+ ``SHA-512(SHA-512(master_key))``, but this particular scheme is not
+ required. Also, the master key need not be in the keyring yet when
+ FS_IOC_SET_ENCRYPTION_POLICY is executed. However, it must be added
+ before any files can be created in the encrypted directory.
+
+If the file is not yet encrypted, then FS_IOC_SET_ENCRYPTION_POLICY
+verifies that the file is an empty directory. If so, the specified
+encryption policy is assigned to the directory, turning it into an
+encrypted directory. After that, and after providing the
+corresponding master key as described in `Adding keys`_, all regular
+files, directories (recursively), and symlinks created in the
+directory will be encrypted, inheriting the same encryption policy.
+The filenames in the directory's entries will be encrypted as well.
+
+Alternatively, if the file is already encrypted, then
+FS_IOC_SET_ENCRYPTION_POLICY validates that the specified encryption
+policy exactly matches the actual one. If they match, then the ioctl
+returns 0. Otherwise, it fails with EEXIST. This works on both
+regular files and directories, including nonempty directories.
+
+Note that the ext4 filesystem does not allow the root directory to be
+encrypted, even if it is empty. Users who want to encrypt an entire
+filesystem with one key should consider using dm-crypt instead.
+
+FS_IOC_SET_ENCRYPTION_POLICY can fail with the following errors:
+
+- ``EACCES``: the file is not owned by the process's uid, nor does the
+ process have the CAP_FOWNER capability in a namespace with the file
+ owner's uid mapped
+- ``EEXIST``: the file is already encrypted with an encryption policy
+ different from the one specified
+- ``EINVAL``: an invalid encryption policy was specified (invalid
+ version, mode(s), or flags)
+- ``ENOTDIR``: the file is unencrypted and is a regular file, not a
+ directory
+- ``ENOTEMPTY``: the file is unencrypted and is a nonempty directory
+- ``ENOTTY``: this type of filesystem does not implement encryption
+- ``EOPNOTSUPP``: the kernel was not configured with encryption
+ support for this filesystem, or the filesystem superblock has not
+ had encryption enabled on it. (For example, to use encryption on an
+ ext4 filesystem, CONFIG_EXT4_ENCRYPTION must be enabled in the
+ kernel config, and the superblock must have had the "encrypt"
+ feature flag enabled using ``tune2fs -O encrypt`` or ``mkfs.ext4 -O
+ encrypt``.)
+- ``EPERM``: this directory may not be encrypted, e.g. because it is
+ the root directory of an ext4 filesystem
+- ``EROFS``: the filesystem is readonly
+
+Getting an encryption policy
+----------------------------
+
+The FS_IOC_GET_ENCRYPTION_POLICY ioctl retrieves the :c:type:`struct
+fscrypt_policy`, if any, for a directory or regular file. See above
+for the struct definition. No additional permissions are required
+beyond the ability to open the file.
+
+FS_IOC_GET_ENCRYPTION_POLICY can fail with the following errors:
+
+- ``EINVAL``: the file is encrypted, but it uses an unrecognized
+ encryption context format
+- ``ENODATA``: the file is not encrypted
+- ``ENOTTY``: this type of filesystem does not implement encryption
+- ``EOPNOTSUPP``: the kernel was not configured with encryption
+ support for this filesystem
+
+Note: if you only need to know whether a file is encrypted or not, on
+most filesystems it is also possible to use the FS_IOC_GETFLAGS ioctl
+and check for FS_ENCRYPT_FL, or to use the statx() system call and
+check for STATX_ATTR_ENCRYPTED in stx_attributes.
+
+Getting the per-filesystem salt
+-------------------------------
+
+Some filesystems, such as ext4 and F2FS, also support the deprecated
+ioctl FS_IOC_GET_ENCRYPTION_PWSALT. This ioctl retrieves a randomly
+generated 16-byte value stored in the filesystem superblock. This
+value is intended to used as a salt when deriving an encryption key
+from a passphrase or other low-entropy user credential.
+
+FS_IOC_GET_ENCRYPTION_PWSALT is deprecated. Instead, prefer to
+generate and manage any needed salt(s) in userspace.
+
+Adding keys
+-----------
+
+To provide a master key, userspace must add it to an appropriate
+keyring using the add_key() system call (see:
+``Documentation/security/keys/core.rst``). The key type must be
+"logon"; keys of this type are kept in kernel memory and cannot be
+read back by userspace. The key description must be "fscrypt:"
+followed by the 16-character lower case hex representation of the
+``master_key_descriptor`` that was set in the encryption policy. The
+key payload must conform to the following structure::
+
+ #define FS_MAX_KEY_SIZE 64
+
+ struct fscrypt_key {
+ u32 mode;
+ u8 raw[FS_MAX_KEY_SIZE];
+ u32 size;
+ };
+
+``mode`` is ignored; just set it to 0. The actual key is provided in
+``raw`` with ``size`` indicating its size in bytes. That is, the
+bytes ``raw[0..size-1]`` (inclusive) are the actual key.
+
+The key description prefix "fscrypt:" may alternatively be replaced
+with a filesystem-specific prefix such as "ext4:". However, the
+filesystem-specific prefixes are deprecated and should not be used in
+new programs.
+
+There are several different types of keyrings in which encryption keys
+may be placed, such as a session keyring, a user session keyring, or a
+user keyring. Each key must be placed in a keyring that is "attached"
+to all processes that might need to access files encrypted with it, in
+the sense that request_key() will find the key. Generally, if only
+processes belonging to a specific user need to access a given
+encrypted directory and no session keyring has been installed, then
+that directory's key should be placed in that user's user session
+keyring or user keyring. Otherwise, a session keyring should be
+installed if needed, and the key should be linked into that session
+keyring, or in a keyring linked into that session keyring.
+
+Note: introducing the complex visibility semantics of keyrings here
+was arguably a mistake --- especially given that by design, after any
+process successfully opens an encrypted file (thereby setting up the
+per-file key), possessing the keyring key is not actually required for
+any process to read/write the file until its in-memory inode is
+evicted. In the future there probably should be a way to provide keys
+directly to the filesystem instead, which would make the intended
+semantics clearer.
+
+Access semantics
+================
+
+With the key
+------------
+
+With the encryption key, encrypted regular files, directories, and
+symlinks behave very similarly to their unencrypted counterparts ---
+after all, the encryption is intended to be transparent. However,
+astute users may notice some differences in behavior:
+
+- Unencrypted files, or files encrypted with a different encryption
+ policy (i.e. different key, modes, or flags), cannot be renamed or
+ linked into an encrypted directory; see `Encryption policy
+ enforcement`_. Attempts to do so will fail with EPERM. However,
+ encrypted files can be renamed within an encrypted directory, or
+ into an unencrypted directory.
+
+- Direct I/O is not supported on encrypted files. Attempts to use
+ direct I/O on such files will fall back to buffered I/O.
+
+- The fallocate operations FALLOC_FL_COLLAPSE_RANGE,
+ FALLOC_FL_INSERT_RANGE, and FALLOC_FL_ZERO_RANGE are not supported
+ on encrypted files and will fail with EOPNOTSUPP.
+
+- Online defragmentation of encrypted files is not supported. The
+ EXT4_IOC_MOVE_EXT and F2FS_IOC_MOVE_RANGE ioctls will fail with
+ EOPNOTSUPP.
+
+- The ext4 filesystem does not support data journaling with encrypted
+ regular files. It will fall back to ordered data mode instead.
+
+- DAX (Direct Access) is not supported on encrypted files.
+
+- The st_size of an encrypted symlink will not necessarily give the
+ length of the symlink target as required by POSIX. It will actually
+ give the length of the ciphertext, which may be slightly longer than
+ the plaintext due to the NUL-padding.
+
+Note that mmap *is* supported. This is possible because the pagecache
+for an encrypted file contains the plaintext, not the ciphertext.
+
+Without the key
+---------------
+
+Some filesystem operations may be performed on encrypted regular
+files, directories, and symlinks even before their encryption key has
+been provided:
+
+- File metadata may be read, e.g. using stat().
+
+- Directories may be listed, in which case the filenames will be
+ listed in an encoded form derived from their ciphertext. The
+ current encoding algorithm is described in `Filename hashing and
+ encoding`_. The algorithm is subject to change, but it is
+ guaranteed that the presented filenames will be no longer than
+ NAME_MAX bytes, will not contain the ``/`` or ``\0`` characters, and
+ will uniquely identify directory entries.
+
+ The ``.`` and ``..`` directory entries are special. They are always
+ present and are not encrypted or encoded.
+
+- Files may be deleted. That is, nondirectory files may be deleted
+ with unlink() as usual, and empty directories may be deleted with
+ rmdir() as usual. Therefore, ``rm`` and ``rm -r`` will work as
+ expected.
+
+- Symlink targets may be read and followed, but they will be presented
+ in encrypted form, similar to filenames in directories. Hence, they
+ are unlikely to point to anywhere useful.
+
+Without the key, regular files cannot be opened or truncated.
+Attempts to do so will fail with ENOKEY. This implies that any
+regular file operations that require a file descriptor, such as
+read(), write(), mmap(), fallocate(), and ioctl(), are also forbidden.
+
+Also without the key, files of any type (including directories) cannot
+be created or linked into an encrypted directory, nor can a name in an
+encrypted directory be the source or target of a rename, nor can an
+O_TMPFILE temporary file be created in an encrypted directory. All
+such operations will fail with ENOKEY.
+
+It is not currently possible to backup and restore encrypted files
+without the encryption key. This would require special APIs which
+have not yet been implemented.
+
+Encryption policy enforcement
+=============================
+
+After an encryption policy has been set on a directory, all regular
+files, directories, and symbolic links created in that directory
+(recursively) will inherit that encryption policy. Special files ---
+that is, named pipes, device nodes, and UNIX domain sockets --- will
+not be encrypted.
+
+Except for those special files, it is forbidden to have unencrypted
+files, or files encrypted with a different encryption policy, in an
+encrypted directory tree. Attempts to link or rename such a file into
+an encrypted directory will fail with EPERM. This is also enforced
+during ->lookup() to provide limited protection against offline
+attacks that try to disable or downgrade encryption in known locations
+where applications may later write sensitive data. It is recommended
+that systems implementing a form of "verified boot" take advantage of
+this by validating all top-level encryption policies prior to access.
+
+Implementation details
+======================
+
+Encryption context
+------------------
+
+An encryption policy is represented on-disk by a :c:type:`struct
+fscrypt_context`. It is up to individual filesystems to decide where
+to store it, but normally it would be stored in a hidden extended
+attribute. It should *not* be exposed by the xattr-related system
+calls such as getxattr() and setxattr() because of the special
+semantics of the encryption xattr. (In particular, there would be
+much confusion if an encryption policy were to be added to or removed
+from anything other than an empty directory.) The struct is defined
+as follows::
+
+ #define FS_KEY_DESCRIPTOR_SIZE 8
+ #define FS_KEY_DERIVATION_NONCE_SIZE 16
+
+ struct fscrypt_context {
+ u8 format;
+ u8 contents_encryption_mode;
+ u8 filenames_encryption_mode;
+ u8 flags;
+ u8 master_key_descriptor[FS_KEY_DESCRIPTOR_SIZE];
+ u8 nonce[FS_KEY_DERIVATION_NONCE_SIZE];
+ };
+
+Note that :c:type:`struct fscrypt_context` contains the same
+information as :c:type:`struct fscrypt_policy` (see `Setting an
+encryption policy`_), except that :c:type:`struct fscrypt_context`
+also contains a nonce. The nonce is randomly generated by the kernel
+and is used to derive the inode's encryption key as described in
+`Per-file keys`_.
+
+Data path changes
+-----------------
+
+For the read path (->readpage()) of regular files, filesystems can
+read the ciphertext into the page cache and decrypt it in-place. The
+page lock must be held until decryption has finished, to prevent the
+page from becoming visible to userspace prematurely.
+
+For the write path (->writepage()) of regular files, filesystems
+cannot encrypt data in-place in the page cache, since the cached
+plaintext must be preserved. Instead, filesystems must encrypt into a
+temporary buffer or "bounce page", then write out the temporary
+buffer. Some filesystems, such as UBIFS, already use temporary
+buffers regardless of encryption. Other filesystems, such as ext4 and
+F2FS, have to allocate bounce pages specially for encryption.
+
+Filename hashing and encoding
+-----------------------------
+
+Modern filesystems accelerate directory lookups by using indexed
+directories. An indexed directory is organized as a tree keyed by
+filename hashes. When a ->lookup() is requested, the filesystem
+normally hashes the filename being looked up so that it can quickly
+find the corresponding directory entry, if any.
+
+With encryption, lookups must be supported and efficient both with and
+without the encryption key. Clearly, it would not work to hash the
+plaintext filenames, since the plaintext filenames are unavailable
+without the key. (Hashing the plaintext filenames would also make it
+impossible for the filesystem's fsck tool to optimize encrypted
+directories.) Instead, filesystems hash the ciphertext filenames,
+i.e. the bytes actually stored on-disk in the directory entries. When
+asked to do a ->lookup() with the key, the filesystem just encrypts
+the user-supplied name to get the ciphertext.
+
+Lookups without the key are more complicated. The raw ciphertext may
+contain the ``\0`` and ``/`` characters, which are illegal in
+filenames. Therefore, readdir() must base64-encode the ciphertext for
+presentation. For most filenames, this works fine; on ->lookup(), the
+filesystem just base64-decodes the user-supplied name to get back to
+the raw ciphertext.
+
+However, for very long filenames, base64 encoding would cause the
+filename length to exceed NAME_MAX. To prevent this, readdir()
+actually presents long filenames in an abbreviated form which encodes
+a strong "hash" of the ciphertext filename, along with the optional
+filesystem-specific hash(es) needed for directory lookups. This
+allows the filesystem to still, with a high degree of confidence, map
+the filename given in ->lookup() back to a particular directory entry
+that was previously listed by readdir(). See :c:type:`struct
+fscrypt_digested_name` in the source for more details.
+
+Note that the precise way that filenames are presented to userspace
+without the key is subject to change in the future. It is only meant
+as a way to temporarily present valid filenames so that commands like
+``rm -r`` work as expected on encrypted directories.

:doc: driver specific ioctls
+Recommended IOCTL Return Values
+-------------------------------
+
+In theory a driver's IOCTL callback is only allowed to return very few error
+codes. In practice it's good to abuse a few more. This section documents common
+practice within the DRM subsystem:
+
+ENOENT:
+ Strictly this should only be used when a file doesn't exist e.g. when
+ calling the open() syscall. We reuse that to signal any kind of object
+ lookup failure, e.g. for unknown GEM buffer object handles, unknown KMS
+ object handles and similar cases.
+
+ENOSPC:
+ Some drivers use this to differentiate "out of kernel memory" from "out
+ of VRAM". Sometimes also applies to other limited gpu resources used for
+ rendering (e.g. when you have a special limited compression buffer).
+ Sometimes resource allocation/reservation issues in command submission
+ IOCTLs are also signalled through EDEADLK.
+
+ Simply running out of kernel/system memory is signalled through ENOMEM.
+
+EPERM/EACCESS:
+ Returned for an operation that is valid, but needs more privileges.
+ E.g. root-only or much more common, DRM master-only operations return
+ this when when called by unpriviledged clients. There's no clear
+ difference between EACCESS and EPERM.
+
+ENODEV:
+ Feature (like PRIME, modesetting, GEM) is not supported by the driver.
+
+ENXIO:
+ Remote failure, either a hardware transaction (like i2c), but also used
+ when the exporting driver of a shared dma-buf or fence doesn't support a
+ feature needed.
+
+EINTR:
+ DRM drivers assume that userspace restarts all IOCTLs. Any DRM IOCTL can
+ return EINTR and in such a case should be restarted with the IOCTL
+ parameters left unchanged.
+
+EIO:
+ The GPU died and couldn't be resurrected through a reset. Modesetting
+ hardware failures are signalled through the "link status" connector
+ property.
+
+EINVAL:
+ Catch-all for anything that is an invalid argument combination which
+ cannot work.
+
+IOCTL also use other error codes like ETIME, EFAULT, EBUSY, ENOTTY but their
+usage is in line with the common meanings. The above list tries to just document
+DRM specific patterns. Note that ENOTTY has the slightly unintuitive meaning of
+"this IOCTL does not exist", and is used exactly as such in DRM.

-How Does a Jprobe Work?
------------------------
-
-A jprobe is implemented using a kprobe that is placed on a function's
-entry point. It employs a simple mirroring principle to allow
-seamless access to the probed function's arguments. The jprobe
-handler routine should have the same signature (arg list and return
-type) as the function being probed, and must always end by calling
-the Kprobes function jprobe_return().
-
-Here's how it works. When the probe is hit, Kprobes makes a copy of
-the saved registers and a generous portion of the stack (see below).
-Kprobes then points the saved instruction pointer at the jprobe's
-handler routine, and returns from the trap. As a result, control
-passes to the handler, which is presented with the same register and
-stack contents as the probed function. When it is done, the handler
-calls jprobe_return(), which traps again to restore the original stack
-contents and processor state and switch to the probed function.
-
-By convention, the callee owns its arguments, so gcc may produce code
-that unexpectedly modifies that portion of the stack. This is why
-Kprobes saves a copy of the stack and restores it after the jprobe
-handler has run. Up to MAX_STACK_SIZE bytes are copied -- e.g.,
-64 bytes on i386.
-
-Note that the probed function's args may be passed on the stack
-or in registers. The jprobe will work in either case, so long as the
-handler's prototype matches that of the probed function.
-
-Note that in some architectures (e.g.: arm64 and sparc64) the stack
-copy is not done, as the actual location of stacked parameters may be
-outside of a reasonable MAX_STACK_SIZE value and because that location
-cannot be determined by the jprobes code. In this case the jprobes
-user must be careful to make certain the calling signature of the
-function does not cause parameters to be passed on the stack (e.g.:
-more than eight function arguments, an argument of more than sixteen
-bytes, or more than 64 bytes of argument data, depending on
-architecture).

+======================
+(Un)patching Callbacks
+======================
+
+Livepatch (un)patch-callbacks provide a mechanism for livepatch modules
+to execute callback functions when a kernel object is (un)patched. They
+can be considered a "power feature" that extends livepatching abilities
+to include:
+
+ - Safe updates to global data
+
+ - "Patches" to init and probe functions
+
+ - Patching otherwise unpatchable code (i.e. assembly)
+
+In most cases, (un)patch callbacks will need to be used in conjunction
+with memory barriers and kernel synchronization primitives, like
+mutexes/spinlocks, or even stop_machine(), to avoid concurrency issues.
+
+Callbacks differ from existing kernel facilities:
+
+ - Module init/exit code doesn't run when disabling and re-enabling a
+ patch.
+
+ - A module notifier can't stop a to-be-patched module from loading.
+
+Callbacks are part of the klp_object structure and their implementation
+is specific to that klp_object. Other livepatch objects may or may not
+be patched, irrespective of the target klp_object's current state.
+
+Callbacks can be registered for the following livepatch actions:
+
+ * Pre-patch - before a klp_object is patched
+
+ * Post-patch - after a klp_object has been patched and is active
+ across all tasks
+
+ * Pre-unpatch - before a klp_object is unpatched (ie, patched code is
+ active), used to clean up post-patch callback
+ resources
+
+ * Post-unpatch - after a klp_object has been patched, all code has
+ been restored and no tasks are running patched code,
+ used to cleanup pre-patch callback resources
+
+Each callback is optional, omitting one does not preclude specifying any
+other. However, the livepatching core executes the handlers in
+symmetry: pre-patch callbacks have a post-unpatch counterpart and
+post-patch callbacks have a pre-unpatch counterpart. An unpatch
+callback will only be executed if its corresponding patch callback was
+executed. Typical use cases pair a patch handler that acquires and
+configures resources with an unpatch handler tears down and releases
+those same resources.
+
+A callback is only executed if its host klp_object is loaded. For
+in-kernel vmlinux targets, this means that callbacks will always execute
+when a livepatch is enabled/disabled. For patch target kernel modules,
+callbacks will only execute if the target module is loaded. When a
+module target is (un)loaded, its callbacks will execute only if the
+livepatch module is enabled.
+
+The pre-patch callback, if specified, is expected to return a status
+code (0 for success, -ERRNO on error). An error status code indicates
+to the livepatching core that patching of the current klp_object is not
+safe and to stop the current patching request. (When no pre-patch
+callback is provided, the transition is assumed to be safe.) If a
+pre-patch callback returns failure, the kernel's module loader will:
+
+ - Refuse to load a livepatch, if the livepatch is loaded after
+ targeted code.
+
+ or:
+
+ - Refuse to load a module, if the livepatch was already successfully
+ loaded.
+
+No post-patch, pre-unpatch, or post-unpatch callbacks will be executed
+for a given klp_object if the object failed to patch, due to a failed
+pre_patch callback or for any other reason.
+
+If a patch transition is reversed, no pre-unpatch handlers will be run
+(this follows the previously mentioned symmetry -- pre-unpatch callbacks
+will only occur if their corresponding post-patch callback executed).
+
+If the object did successfully patch, but the patch transition never
+started for some reason (e.g., if another object failed to patch),
+only the post-unpatch callback will be called.
+
+
+Example Use-cases
+=================
+
+Update global data
+------------------
+
+A pre-patch callback can be useful to update a global variable. For
+example, 75ff39ccc1bd ("tcp: make challenge acks less predictable")
+changes a global sysctl, as well as patches the tcp_send_challenge_ack()
+function.
+
+In this case, if we're being super paranoid, it might make sense to
+patch the data *after* patching is complete with a post-patch callback,
+so that tcp_send_challenge_ack() could first be changed to read
+sysctl_tcp_challenge_ack_limit with READ_ONCE.
+
+
+Support __init and probe function patches
+-----------------------------------------
+
+Although __init and probe functions are not directly livepatch-able, it
+may be possible to implement similar updates via pre/post-patch
+callbacks.
+
+48900cb6af42 ("virtio-net: drop NETIF_F_FRAGLIST") change the way that
+virtnet_probe() initialized its driver's net_device features. A
+pre/post-patch callback could iterate over all such devices, making a
+similar change to their hw_features value. (Client functions of the
+value may need to be updated accordingly.)
+
+
+Test cases
+==========
+
+What follows is not an exhaustive test suite of every possible livepatch
+pre/post-(un)patch combination, but a selection that demonstrates a few
+important concepts. Each test case uses the kernel modules located in
+the samples/livepatch/ and assumes that no livepatches are loaded at the
+beginning of the test.
+
+
+Test 1
+------
+
+Test a combination of loading a kernel module and a livepatch that
+patches a function in the first module. (Un)load the target module
+before the livepatch module:
+

+- disable livepatch
+- unload target module
+- unload livepatch
+
+First load a target module:

+ % insmod samples/livepatch/livepatch-callbacks-mod.ko
+ [ 34.475708] livepatch_callbacks_mod: livepatch_callbacks_mod_init
+
+On livepatch enable, before the livepatch transition starts, pre-patch
+callbacks are executed for vmlinux and livepatch_callbacks_mod (those
+klp_objects currently loaded). After klp_objects are patched according
+to the klp_patch, their post-patch callbacks run and the transition
+completes:
+
+ % insmod samples/livepatch/livepatch-callbacks-demo.ko

+
+Similarly, on livepatch disable, pre-patch callbacks run before the
+unpatching transition starts. klp_objects are reverted, post-patch
+callbacks execute and the transition completes:

+------
+
+A simple test of loading a livepatch without one of its patch target

+Test 6
+------
+
+Test a scenario where a vmlinux pre-patch callback returns a non-zero
+status (ie, failure):
+
+- load target module
+- load livepatch -ENODEV
+- unload target module
+
+First load a target module:
+
+ % insmod samples/livepatch/livepatch-callbacks-mod.ko
+ [ 80.740520] livepatch_callbacks_mod: livepatch_callbacks_mod_init
+
+Load the livepatch module, setting its 'pre_patch_ret' value to -19
+(-ENODEV). When its vmlinux pre-patch callback executed, this status
+code will propagate back to the module-loading subsystem. The result is

+------
+
+Similar to the previous test, setup a livepatch such that its vmlinux
+pre-patch callback returns success. However, when a targeted kernel
+module is later loaded, have the livepatch return a failing status code:
+
+- load livepatch
+- setup -ENODEV
+- load target module
+- disable livepatch
+- unload livepatch
+
+Load the livepatch, notice vmlinux pre-patch callback succeeds:

+
+Set a trap so subsequent pre-patch callbacks to this livepatch will
+return -ENODEV:
+
+ % echo -19 > /sys/module/livepatch_callbacks_demo/parameters/pre_patch_ret
+
+The livepatch pre-patch callback for subsequently loaded target modules
+will return failure, so the module loader refuses to load the kernel
+module. Notice that no post-patch or pre/post-unpatch callbacks are
+executed for this klp_object:

+Test 9
+------
+
+A similar test as the previous one, but force the "busy" kernel module
+to do longer work.
+
+The livepatching core will refuse to patch a task that is currently
+executing a to-be-patched function -- the consistency model stalls the
+current patch transition until this safety-check is met. Test a
+scenario where one of a livepatch's target klp_objects sits on such a
+function for a long time. Meanwhile, load and unload other target
+kernel modules while the livepatch transition is in progress.
+
+- load busy target module (30s sleep)
+- load livepatch
+- load target module
+- unload target module
+- disable livepatch
+- unload livepatch
+- unload busy target module
+
+
+Load the "busy" kernel module, this time make it do 30 seconds worth of
+work:
+
+ % insmod samples/livepatch/livepatch-callbacks-busymod.ko sleep_secs=30
+ [ 110.993362] livepatch_callbacks_busymod: livepatch_callbacks_mod_init
+ [ 110.994059] livepatch_callbacks_busymod: busymod_work_func, sleeping 30 seconds ...
+
+Meanwhile, the livepatch is loaded. Notice that the patch transition
+does not complete as the targeted "busy" module is sitting on a
+to-be-patched function:
+
+ % insmod samples/livepatch/livepatch-callbacks-demo.ko
+ [ 113.000309] livepatch: enabling patch 'livepatch_callbacks_demo'
+ [ 113.000764] livepatch: 'livepatch_callbacks_demo': initializing patching transition

+ [ 113.005208] livepatch: 'livepatch_callbacks_demo': starting patching transition
+
+Load a second target module (this one is an ordinary idle kernel
+module). Note that *no* post-patch callbacks will be executed while the
+livepatch is still in transition:
+
+ % insmod samples/livepatch/livepatch-callbacks-mod.ko

+ [ 115.015315] livepatch_callbacks_mod: livepatch_callbacks_mod_init
+
+Request an unload of the simple kernel module. The patch is still
+transitioning, so its pre-unpatch callbacks are skipped:
+
+ % rmmod samples/livepatch/livepatch-callbacks-mod.ko

+ [ 117.024533] livepatch_callbacks_demo: post_unpatch_callback: livepatch_callbacks_mod -> [MODULE_STATE_GOING] Going away
+
+Finally the livepatch is disabled. Since none of the patch's
+klp_object's post-patch callbacks executed, the remaining klp_object's
+pre-unpatch callbacks are skipped:

+================
+Shadow Variables
+================
+
+Shadow variables are a simple way for livepatch modules to associate
+additional "shadow" data with existing data structures. Shadow data is
+allocated separately from parent data structures, which are left
+unmodified. The shadow variable API described in this document is used
+to allocate/add and remove/free shadow variables to/from their parents.
+
+The implementation introduces a global, in-kernel hashtable that
+associates pointers to parent objects and a numeric identifier of the
+shadow data. The numeric identifier is a simple enumeration that may be
+used to describe shadow variable version, class or type, etc. More
+specifically, the parent pointer serves as the hashtable key while the
+numeric id subsequently filters hashtable queries. Multiple shadow
+variables may attach to the same parent object, but their numeric
+identifier distinguishes between them.
+
+
+1. Brief API summary
+====================
+
+(See the full API usage docbook notes in livepatch/shadow.c.)
+
+A hashtable references all shadow variables. These references are
+stored and retrieved through a <obj, id> pair.
+
+* The klp_shadow variable data structure encapsulates both tracking
+meta-data and shadow-data:
+ - meta-data
+ - obj - pointer to parent object
+ - id - data identifier
+ - data[] - storage for shadow data
+
+It is important to note that the klp_shadow_alloc() and
+klp_shadow_get_or_alloc() calls, described below, store a *copy* of the
+data that the functions are provided. Callers should provide whatever
+mutual exclusion is required of the shadow data.
+
+* klp_shadow_get() - retrieve a shadow variable data pointer
+ - search hashtable for <obj, id> pair
+
+* klp_shadow_alloc() - allocate and add a new shadow variable
+ - search hashtable for <obj, id> pair
+ - if exists
+ - WARN and return NULL
+ - if <obj, id> doesn't already exist
+ - allocate a new shadow variable
+ - copy data into the new shadow variable
+ - add <obj, id> to the global hashtable
+
+* klp_shadow_get_or_alloc() - get existing or alloc a new shadow variable
+ - search hashtable for <obj, id> pair
+ - if exists
+ - return existing shadow variable
+ - if <obj, id> doesn't already exist
+ - allocate a new shadow variable
+ - copy data into the new shadow variable
+ - add <obj, id> pair to the global hashtable
+
+* klp_shadow_free() - detach and free a <obj, id> shadow variable
+ - find and remove a <obj, id> reference from global hashtable
+ - if found, free shadow variable
+
+* klp_shadow_free_all() - detach and free all <*, id> shadow variables
+ - find and remove any <*, id> references from global hashtable
+ - if found, free shadow variable
+
+
+2. Use cases
+============
+
+(See the example shadow variable livepatch modules in samples/livepatch/
+for full working demonstrations.)
+
+For the following use-case examples, consider commit 1d147bfa6429
+("mac80211: fix AP powersave TX vs. wakeup race"), which added a
+spinlock to net/mac80211/sta_info.h :: struct sta_info. Each use-case
+example can be considered a stand-alone livepatch implementation of this
+fix.
+
+
+Matching parent's lifecycle
+---------------------------
+
+If parent data structures are frequently created and destroyed, it may
+be easiest to align their shadow variables lifetimes to the same
+allocation and release functions. In this case, the parent data
+structure is typically allocated, initialized, then registered in some
+manner. Shadow variable allocation and setup can then be considered
+part of the parent's initialization and should be completed before the
+parent "goes live" (ie, any shadow variable get-API requests are made
+for this <obj, id> pair.)
+
+For commit 1d147bfa6429, when a parent sta_info structure is allocated,
+allocate a shadow copy of the ps_lock pointer, then initialize it:
+
+#define PS_LOCK 1
+struct sta_info *sta_info_alloc(struct ieee80211_sub_if_data *sdata,
+ const u8 *addr, gfp_t gfp)
+{
+ struct sta_info *sta;
+ spinlock_t *ps_lock;
+
+ /* Parent structure is created */
+ sta = kzalloc(sizeof(*sta) + hw->sta_data_size, gfp);
+
+ /* Attach a corresponding shadow variable, then initialize it */
+ ps_lock = klp_shadow_alloc(sta, PS_LOCK, NULL, sizeof(*ps_lock), gfp);
+ if (!ps_lock)
+ goto shadow_fail;
+ spin_lock_init(ps_lock);
+ ...
+
+When requiring a ps_lock, query the shadow variable API to retrieve one
+for a specific struct sta_info:
+
+void ieee80211_sta_ps_deliver_wakeup(struct sta_info *sta)
+{
+ spinlock_t *ps_lock;
+
+ /* sync with ieee80211_tx_h_unicast_ps_buf */
+ ps_lock = klp_shadow_get(sta, PS_LOCK);
+ if (ps_lock)
+ spin_lock(ps_lock);
+ ...
+
+When the parent sta_info structure is freed, first free the shadow
+variable:
+
+void sta_info_free(struct ieee80211_local *local, struct sta_info *sta)
+{
+ klp_shadow_free(sta, PS_LOCK);
+ kfree(sta);
+ ...
+
+
+In-flight parent objects
+------------------------
+
+Sometimes it may not be convenient or possible to allocate shadow
+variables alongside their parent objects. Or a livepatch fix may
+require shadow varibles to only a subset of parent object instances. In
+these cases, the klp_shadow_get_or_alloc() call can be used to attach
+shadow variables to parents already in-flight.
+
+For commit 1d147bfa6429, a good spot to allocate a shadow spinlock is
+inside ieee80211_sta_ps_deliver_wakeup():
+
+#define PS_LOCK 1
+void ieee80211_sta_ps_deliver_wakeup(struct sta_info *sta)
+{
+ DEFINE_SPINLOCK(ps_lock_fallback);
+ spinlock_t *ps_lock;
+
+ /* sync with ieee80211_tx_h_unicast_ps_buf */
+ ps_lock = klp_shadow_get_or_alloc(sta, PS_LOCK,
+ &ps_lock_fallback, sizeof(ps_lock_fallback),
+ GFP_ATOMIC);
+ if (ps_lock)
+ spin_lock(ps_lock);
+ ...
+
+This usage will create a shadow variable, only if needed, otherwise it
+will use one that was already created for this <obj, id> pair.
+
+Like the previous use-case, the shadow spinlock needs to be cleaned up.
+A shadow variable can be freed just before its parent object is freed,
+or even when the shadow variable itself is no longer required.
+
+
+Other use-cases
+---------------
+
+Shadow variables can also be used as a flag indicating that a data
+structure was allocated by new, livepatched code. In this case, it
+doesn't matter what data value the shadow variable holds, its existence
+suggests how to handle the parent object.

-
-The Digital TV Frontend kABI defines a driver-internal interface for
-registering low-level, hardware specific driver to a hardware independent

-The header file for this API is named ``dvb_frontend.h`` and located in
-``drivers/media/dvb-core``.
-
-Demodulator driver
-^^^^^^^^^^^^^^^^^^
-
-The demodulator driver is responsible to talk with the decoding part of the

-series of functions that allow the DVB core to command the hardware via
-the code under ``drivers/media/dvb-core/dvb_frontend.c``.
-
-A typical example of such struct in a driver ``foo`` is::

-Digital TV Frontend statistics
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Introduction
-^^^^^^^^^^^^
-
-Digital TV frontends provide a range of
-:ref:`statistics <frontend-stat-properties>` meant to help tuning the device
-and measuring the quality of service.
-
-For each statistics measurement, the driver should set the type of scale used,
-or ``FE_SCALE_NOT_AVAILABLE`` if the statistics is not available on a given
-time. Drivers should also provide the number of statistics for each type.
-that's usually 1 for most video standards [#f2]_.
-
-Drivers should initialize each statistic counters with length and
-scale at its init code. For example, if the frontend provides signal
-strength, it should have, on its init code::
-
- struct dtv_frontend_properties *c = &state->fe.dtv_property_cache;
-
- c->strength.len = 1;
- c->strength.stat[0].scale = FE_SCALE_NOT_AVAILABLE;
-
-And, when the statistics got updated, set the scale::
-
- c->strength.stat[0].scale = FE_SCALE_DECIBEL;
- c->strength.stat[0].uvalue = strength;
-
-.. [#f2] For ISDB-T, it may provide both a global statistics and a per-layer
- set of statistics. On such cases, len should be equal to 4. The first
- value corresponds to the global stat; the other ones to each layer, e. g.:
-
- - c->cnr.stat[0] for global S/N carrier ratio,
- - c->cnr.stat[1] for Layer A S/N carrier ratio,
- - c->cnr.stat[2] for layer B S/N carrier ratio,
- - c->cnr.stat[3] for layer C S/N carrier ratio.
-
-.. note:: Please prefer to use ``FE_SCALE_DECIBEL`` instead of
- ``FE_SCALE_RELATIVE`` for signal strength and CNR measurements.
-
-Groups of statistics
-^^^^^^^^^^^^^^^^^^^^
-
-There are several groups of statistics currently supported:
-
-Signal strength (:ref:`DTV-STAT-SIGNAL-STRENGTH`)
- - Measures the signal strength level at the analog part of the tuner or
- demod.
-
- - Typically obtained from the gain applied to the tuner and/or frontend
- in order to detect the carrier. When no carrier is detected, the gain is
- at the maximum value (so, strength is on its minimal).
-
- - As the gain is visible through the set of registers that adjust the gain,
- typically, this statistics is always available [#f3]_.
-
- - Drivers should try to make it available all the times, as this statistics
- can be used when adjusting an antenna position and to check for troubles
- at the cabling.
-
- .. [#f3] On a few devices, the gain keeps floating if no carrier.
- On such devices, strength report should check first if carrier is
- detected at the tuner (``FE_HAS_CARRIER``, see :c:type:`fe_status`),
- and otherwise return the lowest possible value.
-
-Carrier Signal to Noise ratio (:ref:`DTV-STAT-CNR`)
- - Signal to Noise ratio for the main carrier.
-
- - Signal to Noise measurement depends on the device. On some hardware, is
- available when the main carrier is detected. On those hardware, CNR
- measurement usually comes from the tuner (e. g. after ``FE_HAS_CARRIER``,
- see :c:type:`fe_status`).
-
- On other devices, it requires inner FEC decoding,
- as the frontend measures it indirectly from other parameters (e. g. after
- ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
-
- Having it available after inner FEC is more common.
-
-Bit counts post-FEC (:ref:`DTV-STAT-POST-ERROR-BIT-COUNT` and :ref:`DTV-STAT-POST-TOTAL-BIT-COUNT`)
- - Those counters measure the number of bits and bit errors errors after
- the forward error correction (FEC) on the inner coding block
- (after Viterbi, LDPC or other inner code).
-
- - Due to its nature, those statistics depend on full coding lock
- (e. g. after ``FE_HAS_SYNC`` or after ``FE_HAS_LOCK``,
- see :c:type:`fe_status`).
-
-Bit counts pre-FEC (:ref:`DTV-STAT-PRE-ERROR-BIT-COUNT` and :ref:`DTV-STAT-PRE-TOTAL-BIT-COUNT`)
- - Those counters measure the number of bits and bit errors errors before
- the forward error correction (FEC) on the inner coding block
- (before Viterbi, LDPC or other inner code).
-
- - Not all frontends provide this kind of statistics.
-
- - Due to its nature, those statistics depend on inner coding lock (e. g.
- after ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
-
-Block counts (:ref:`DTV-STAT-ERROR-BLOCK-COUNT` and :ref:`DTV-STAT-TOTAL-BLOCK-COUNT`)
- - Those counters measure the number of blocks and block errors errors after
- the forward error correction (FEC) on the inner coding block
- (before Viterbi, LDPC or other inner code).
-
- - Due to its nature, those statistics depend on full coding lock
- (e. g. after ``FE_HAS_SYNC`` or after
- ``FE_HAS_LOCK``, see :c:type:`fe_status`).
-
-.. note:: All counters should be monotonically increased as they're
- collected from the hardware.
-
-A typical example of the logic that handle status and statistics is::
-
- static int foo_get_status_and_stats(struct dvb_frontend *fe)
- {
- struct foo_state *state = fe->demodulator_priv;
- struct dtv_frontend_properties *c = &fe->dtv_property_cache;
-
- int rc;
- enum fe_status *status;
-
- /* Both status and strength are always available */
- rc = foo_read_status(fe, &status);
- if (rc < 0)
- return rc;
-
- rc = foo_read_strength(fe);
- if (rc < 0)
- return rc;
-
- /* Check if CNR is available */
- if (!(fe->status & FE_HAS_CARRIER))
- return 0;
-
- rc = foo_read_cnr(fe);
- if (rc < 0)
- return rc;
-
- /* Check if pre-BER stats are available */
- if (!(fe->status & FE_HAS_VITERBI))
- return 0;
-
- rc = foo_get_pre_ber(fe);
- if (rc < 0)
- return rc;
-
- /* Check if post-BER stats are available */
- if (!(fe->status & FE_HAS_SYNC))
- return 0;
-
- rc = foo_get_post_ber(fe);
- if (rc < 0)
- return rc;
- }
-
- static const struct dvb_frontend_ops ops = {
- /* ... */
- .read_status = foo_get_status_and_stats,
- };
-
-Statistics collect
-^^^^^^^^^^^^^^^^^^
-
-On almost all frontend hardware, the bit and byte counts are stored by
-the hardware after a certain amount of time or after the total bit/block
-counter reaches a certain value (usually programable), for example, on
-every 1000 ms or after receiving 1,000,000 bits.
-
-So, if you read the registers too soon, you'll end by reading the same
-value as in the previous reading, causing the monotonic value to be
-incremented too often.
-
-Drivers should take the responsibility to avoid too often reads. That
-can be done using two approaches:
-
-if the driver have a bit that indicates when a collected data is ready
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-
-Driver should check such bit before making the statistics available.
-
-An example of such behavior can be found at this code snippet (adapted
-from mb86a20s driver's logic)::
-
- static int foo_get_pre_ber(struct dvb_frontend *fe)
- {
- struct foo_state *state = fe->demodulator_priv;
- struct dtv_frontend_properties *c = &fe->dtv_property_cache;
- int rc, bit_error;
-
- /* Check if the BER measures are already available */
- rc = foo_read_u8(state, 0x54);
- if (rc < 0)
- return rc;
-
- if (!rc)
- return 0;
-
- /* Read Bit Error Count */
- bit_error = foo_read_u32(state, 0x55);
- if (bit_error < 0)
- return bit_error;
-
- /* Read Total Bit Count */
- rc = foo_read_u32(state, 0x51);
- if (rc < 0)
- return rc;
-
- c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
- c->pre_bit_error.stat[0].uvalue += bit_error;
- c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
- c->pre_bit_count.stat[0].uvalue += rc;
-
- return 0;
- }
-
-If the driver doesn't provide a statistics available check bit
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-
-A few devices, however, may not provide a way to check if the stats are
-available (or the way to check it is unknown). They may not even provide
-a way to directly read the total number of bits or blocks.
-
-On those devices, the driver need to ensure that it won't be reading from
-the register too often and/or estimate the total number of bits/blocks.
-
-On such drivers, a typical routine to get statistics would be like
-(adapted from dib8000 driver's logic)::
-
- struct foo_state {
- /* ... */
-
- unsigned long per_jiffies_stats;
- }
-
- static int foo_get_pre_ber(struct dvb_frontend *fe)
- {
- struct foo_state *state = fe->demodulator_priv;
- struct dtv_frontend_properties *c = &fe->dtv_property_cache;
- int rc, bit_error;
- u64 bits;
-
- /* Check if time for stats was elapsed */
- if (!time_after(jiffies, state->per_jiffies_stats))
- return 0;
-
- /* Next stat should be collected in 1000 ms */
- state->per_jiffies_stats = jiffies + msecs_to_jiffies(1000);
-
- /* Read Bit Error Count */
- bit_error = foo_read_u32(state, 0x55);
- if (bit_error < 0)
- return bit_error;
-
- /*
- * On this particular frontend, there's no register that
- * would provide the number of bits per 1000ms sample. So,
- * some function would calculate it based on DTV properties
- */
- bits = get_number_of_bits_per_1000ms(fe);
-
- c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
- c->pre_bit_error.stat[0].uvalue += bit_error;
- c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
- c->pre_bit_count.stat[0].uvalue += bits;
-
- return 0;
- }
-
-Please notice that, on both cases, we're getting the statistics using the
-:c:type:`dvb_frontend_ops` ``.read_status`` callback. The rationale is that
-the frontend core will automatically call this function periodically
-(usually, 3 times per second, when the frontend is locked).
-
-That warrants that we won't miss to collect a counter and increment the
-monotonic stats at the right time.

-
-
-Digital TV Demux kABI
----------------------
-
-Digital TV Demux
-~~~~~~~~~~~~~~~~
-
-The Kernel Digital TV Demux kABI defines a driver-internal interface for
-registering low-level, hardware specific driver to a hardware independent
-demux layer. It is only of interest for Digital TV device driver writers.
-The header file for this kABI is named demux.h and located in
-drivers/media/dvb-core.
-
-The demux kABI should be implemented for each demux in the system. It is
-used to select the TS source of a demux and to manage the demux resources.
-When the demux client allocates a resource via the demux kABI, it receives
-a pointer to the kABI of that resource.
-
-Each demux receives its TS input from a DVB front-end or from memory, as
-set via this demux kABI. In a system with more than one front-end, the kABI
-can be used to select one of the DVB front-ends as a TS source for a demux,
-unless this is fixed in the HW platform.
-
-The demux kABI only controls front-ends regarding to their connections with
-demuxes; the kABI used to set the other front-end parameters, such as
-tuning, are devined via the Digital TV Frontend kABI.
-
-The functions that implement the abstract interface demux should be defined
-static or module private and registered to the Demux core for external
-access. It is not necessary to implement every function in the struct
-&dmx_demux. For example, a demux interface might support Section filtering,
-but not PES filtering. The kABI client is expected to check the value of any
-function pointer before calling the function: the value of ``NULL`` means
-that the function is not available.
-
-Whenever the functions of the demux API modify shared data, the
-possibilities of lost update and race condition problems should be
-addressed, e.g. by protecting parts of code with mutexes.
-
-Note that functions called from a bottom half context must not sleep.
-Even a simple memory allocation without using ``GFP_ATOMIC`` can result in a
-kernel thread being put to sleep if swapping is needed. For example, the
-Linux Kernel calls the functions of a network device interface from a
-bottom half context. Thus, if a demux kABI function is called from network
-device code, the function must not sleep.
-
-
-
-Demux Callback API
-------------------
-
-Demux Callback
-~~~~~~~~~~~~~~
-
-This kernel-space API comprises the callback functions that deliver filtered
-data to the demux client. Unlike the other DVB kABIs, these functions are
-provided by the client and called from the demux code.
-
-The function pointers of this abstract interface are not packed into a
-structure as in the other demux APIs, because the callback functions are
-registered and used independent of each other. As an example, it is possible
-for the API client to provide several callback functions for receiving TS
-packets and no callbacks for PES packets or sections.
-
-The functions that implement the callback API need not be re-entrant: when
-a demux driver calls one of these functions, the driver is not allowed to
-call the function again before the original call returns. If a callback is
-triggered by a hardware interrupt, it is recommended to use the Linux
-bottom half mechanism or start a tasklet instead of making the callback
-function call directly from a hardware interrupt.
-
-This mechanism is implemented by :c:func:`dmx_ts_cb()` and :c:func:`dmx_section_cb()`
-callbacks.

+Digital TV Frontend kABI
+------------------------
+
+Digital TV Frontend
+~~~~~~~~~~~~~~~~~~~
+
+The Digital TV Frontend kABI defines a driver-internal interface for
+registering low-level, hardware specific driver to a hardware independent
+frontend layer. It is only of interest for Digital TV device driver writers.
+The header file for this API is named ``dvb_frontend.h`` and located in
+``drivers/media/dvb-core``.
+
+Demodulator driver
+^^^^^^^^^^^^^^^^^^
+
+The demodulator driver is responsible to talk with the decoding part of the
+hardware. Such driver should implement :c:type:`dvb_frontend_ops`, with
+tells what type of digital TV standards are supported, and points to a
+series of functions that allow the DVB core to command the hardware via
+the code under ``drivers/media/dvb-core/dvb_frontend.c``.
+
+A typical example of such struct in a driver ``foo`` is::
+
+ static struct dvb_frontend_ops foo_ops = {
+ .delsys = { SYS_DVBT, SYS_DVBT2, SYS_DVBC_ANNEX_A },
+ .info = {
+ .name = "foo DVB-T/T2/C driver",
+ .caps = FE_CAN_FEC_1_2 |

+ FE_CAN_QAM_64 |
+ FE_CAN_QAM_128 |
+ FE_CAN_QAM_256 |

+ },

+ .get_frontend = foo_get_frontend,
+ .read_status = foo_get_status_and_stats,
+ .tune = foo_tune,
+ .i2c_gate_ctrl = foo_i2c_gate_ctrl,
+ .get_frontend_algo = foo_get_algo,
+ };
+
+A typical example of such struct in a driver ``bar`` meant to be used on
+Satellite TV reception is::
+
+ static const struct dvb_frontend_ops bar_ops = {
+ .delsys = { SYS_DVBS, SYS_DVBS2 },
+ .info = {
+ .name = "Bar DVB-S/S2 demodulator",
+ .frequency_min = 500000, /* KHz */
+ .frequency_max = 2500000, /* KHz */
+ .frequency_stepsize = 0,
+ .symbol_rate_min = 1000000,
+ .symbol_rate_max = 45000000,
+ .symbol_rate_tolerance = 500,
+ .caps = FE_CAN_INVERSION_AUTO |

+ .diseqc_send_burst = bar_send_burst,
+ .set_tone = bar_set_tone,
+ .set_voltage = bar_set_voltage,
+ };
+
+.. note::
+
+ #) For satellite digital TV standards (DVB-S, DVB-S2, ISDB-S), the
+ frequencies are specified in kHz, while, for terrestrial and cable
+ standards, they're specified in Hz. Due to that, if the same frontend
+ supports both types, you'll need to have two separate
+ :c:type:`dvb_frontend_ops` structures, one for each standard.
+ #) The ``.i2c_gate_ctrl`` field is present only when the hardware has
+ allows controlling an I2C gate (either directly of via some GPIO pin),
+ in order to remove the tuner from the I2C bus after a channel is
+ tuned.
+ #) All new drivers should implement the
+ :ref:`DVBv5 statistics <dvbv5_stats>` via ``.read_status``.
+ Yet, there are a number of callbacks meant to get statistics for
+ signal strength, S/N and UCB. Those are there to provide backward
+ compatibility with legacy applications that don't support the DVBv5
+ API. Implementing those callbacks are optional. Those callbacks may be
+ removed in the future, after we have all existing drivers supporting
+ DVBv5 stats.
+ #) Other callbacks are required for satellite TV standards, in order to
+ control LNBf and DiSEqC: ``.diseqc_send_master_cmd``,
+ ``.diseqc_send_burst``, ``.set_tone``, ``.set_voltage``.
+
+.. |delta| unicode:: U+00394
+
+The ``drivers/media/dvb-core/dvb_frontend.c`` has a kernel thread with is
+responsible for tuning the device. It supports multiple algorithms to
+detect a channel, as defined at enum :c:func:`dvbfe_algo`.
+
+The algorithm to be used is obtained via ``.get_frontend_algo``. If the driver
+doesn't fill its field at struct :c:type:`dvb_frontend_ops`, it will default to
+``DVBFE_ALGO_SW``, meaning that the dvb-core will do a zigzag when tuning,
+e. g. it will try first to use the specified center frequency ``f``,
+then, it will do ``f`` + |delta|, ``f`` - |delta|, ``f`` + 2 x |delta|,
+``f`` - 2 x |delta| and so on.
+
+If the hardware has internally a some sort of zigzag algorithm, you should
+define a ``.get_frontend_algo`` function that would return ``DVBFE_ALGO_HW``.
+
+.. note::
+
+ The core frontend support also supports
+ a third type (``DVBFE_ALGO_CUSTOM``), in order to allow the driver to
+ define its own hardware-assisted algorithm. Very few hardware need to
+ use it nowadays. Using ``DVBFE_ALGO_CUSTOM`` require to provide other
+ function callbacks at struct :c:type:`dvb_frontend_ops`.
+
+Attaching frontend driver to the bridge driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Before using the Digital TV frontend core, the bridge driver should attach
+the frontend demod, tuner and SEC devices and call
+:c:func:`dvb_register_frontend()`,
+in order to register the new frontend at the subsystem. At device
+detach/removal, the bridge driver should call
+:c:func:`dvb_unregister_frontend()` to
+remove the frontend from the core and then :c:func:`dvb_frontend_detach()`
+to free the memory allocated by the frontend drivers.
+
+The drivers should also call :c:func:`dvb_frontend_suspend()` as part of
+their handler for the :c:type:`device_driver`.\ ``suspend()``, and
+:c:func:`dvb_frontend_resume()` as
+part of their handler for :c:type:`device_driver`.\ ``resume()``.
+
+A few other optional functions are provided to handle some special cases.
+
+.. _dvbv5_stats:
+
+Digital TV Frontend statistics
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Introduction
+^^^^^^^^^^^^
+
+Digital TV frontends provide a range of
+:ref:`statistics <frontend-stat-properties>` meant to help tuning the device
+and measuring the quality of service.
+
+For each statistics measurement, the driver should set the type of scale used,
+or ``FE_SCALE_NOT_AVAILABLE`` if the statistics is not available on a given
+time. Drivers should also provide the number of statistics for each type.
+that's usually 1 for most video standards [#f2]_.
+
+Drivers should initialize each statistic counters with length and
+scale at its init code. For example, if the frontend provides signal
+strength, it should have, on its init code::
+
+ struct dtv_frontend_properties *c = &state->fe.dtv_property_cache;
+
+ c->strength.len = 1;
+ c->strength.stat[0].scale = FE_SCALE_NOT_AVAILABLE;
+
+And, when the statistics got updated, set the scale::
+
+ c->strength.stat[0].scale = FE_SCALE_DECIBEL;
+ c->strength.stat[0].uvalue = strength;
+
+.. [#f2] For ISDB-T, it may provide both a global statistics and a per-layer
+ set of statistics. On such cases, len should be equal to 4. The first
+ value corresponds to the global stat; the other ones to each layer, e. g.:
+
+ - c->cnr.stat[0] for global S/N carrier ratio,
+ - c->cnr.stat[1] for Layer A S/N carrier ratio,
+ - c->cnr.stat[2] for layer B S/N carrier ratio,
+ - c->cnr.stat[3] for layer C S/N carrier ratio.
+
+.. note:: Please prefer to use ``FE_SCALE_DECIBEL`` instead of
+ ``FE_SCALE_RELATIVE`` for signal strength and CNR measurements.
+
+Groups of statistics
+^^^^^^^^^^^^^^^^^^^^
+
+There are several groups of statistics currently supported:
+
+Signal strength (:ref:`DTV-STAT-SIGNAL-STRENGTH`)
+ - Measures the signal strength level at the analog part of the tuner or
+ demod.
+
+ - Typically obtained from the gain applied to the tuner and/or frontend
+ in order to detect the carrier. When no carrier is detected, the gain is
+ at the maximum value (so, strength is on its minimal).
+
+ - As the gain is visible through the set of registers that adjust the gain,
+ typically, this statistics is always available [#f3]_.
+
+ - Drivers should try to make it available all the times, as this statistics
+ can be used when adjusting an antenna position and to check for troubles
+ at the cabling.
+
+ .. [#f3] On a few devices, the gain keeps floating if no carrier.
+ On such devices, strength report should check first if carrier is
+ detected at the tuner (``FE_HAS_CARRIER``, see :c:type:`fe_status`),
+ and otherwise return the lowest possible value.
+
+Carrier Signal to Noise ratio (:ref:`DTV-STAT-CNR`)
+ - Signal to Noise ratio for the main carrier.
+
+ - Signal to Noise measurement depends on the device. On some hardware, is
+ available when the main carrier is detected. On those hardware, CNR
+ measurement usually comes from the tuner (e. g. after ``FE_HAS_CARRIER``,
+ see :c:type:`fe_status`).
+
+ On other devices, it requires inner FEC decoding,
+ as the frontend measures it indirectly from other parameters (e. g. after
+ ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
+
+ Having it available after inner FEC is more common.
+
+Bit counts post-FEC (:ref:`DTV-STAT-POST-ERROR-BIT-COUNT` and :ref:`DTV-STAT-POST-TOTAL-BIT-COUNT`)
+ - Those counters measure the number of bits and bit errors errors after
+ the forward error correction (FEC) on the inner coding block
+ (after Viterbi, LDPC or other inner code).
+
+ - Due to its nature, those statistics depend on full coding lock
+ (e. g. after ``FE_HAS_SYNC`` or after ``FE_HAS_LOCK``,
+ see :c:type:`fe_status`).
+
+Bit counts pre-FEC (:ref:`DTV-STAT-PRE-ERROR-BIT-COUNT` and :ref:`DTV-STAT-PRE-TOTAL-BIT-COUNT`)
+ - Those counters measure the number of bits and bit errors errors before
+ the forward error correction (FEC) on the inner coding block
+ (before Viterbi, LDPC or other inner code).
+
+ - Not all frontends provide this kind of statistics.
+
+ - Due to its nature, those statistics depend on inner coding lock (e. g.
+ after ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
+
+Block counts (:ref:`DTV-STAT-ERROR-BLOCK-COUNT` and :ref:`DTV-STAT-TOTAL-BLOCK-COUNT`)
+ - Those counters measure the number of blocks and block errors errors after
+ the forward error correction (FEC) on the inner coding block
+ (before Viterbi, LDPC or other inner code).
+
+ - Due to its nature, those statistics depend on full coding lock
+ (e. g. after ``FE_HAS_SYNC`` or after
+ ``FE_HAS_LOCK``, see :c:type:`fe_status`).
+
+.. note:: All counters should be monotonically increased as they're
+ collected from the hardware.
+
+A typical example of the logic that handle status and statistics is::
+
+ static int foo_get_status_and_stats(struct dvb_frontend *fe)
+ {
+ struct foo_state *state = fe->demodulator_priv;
+ struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+
+ int rc;
+ enum fe_status *status;
+
+ /* Both status and strength are always available */
+ rc = foo_read_status(fe, &status);
+ if (rc < 0)
+ return rc;
+
+ rc = foo_read_strength(fe);
+ if (rc < 0)
+ return rc;
+
+ /* Check if CNR is available */
+ if (!(fe->status & FE_HAS_CARRIER))
+ return 0;
+
+ rc = foo_read_cnr(fe);
+ if (rc < 0)
+ return rc;
+
+ /* Check if pre-BER stats are available */
+ if (!(fe->status & FE_HAS_VITERBI))
+ return 0;
+
+ rc = foo_get_pre_ber(fe);
+ if (rc < 0)
+ return rc;
+
+ /* Check if post-BER stats are available */
+ if (!(fe->status & FE_HAS_SYNC))
+ return 0;
+
+ rc = foo_get_post_ber(fe);
+ if (rc < 0)
+ return rc;
+ }
+
+ static const struct dvb_frontend_ops ops = {
+ /* ... */
+ .read_status = foo_get_status_and_stats,
+ };
+
+Statistics collect
+^^^^^^^^^^^^^^^^^^
+
+On almost all frontend hardware, the bit and byte counts are stored by
+the hardware after a certain amount of time or after the total bit/block
+counter reaches a certain value (usually programable), for example, on
+every 1000 ms or after receiving 1,000,000 bits.
+
+So, if you read the registers too soon, you'll end by reading the same
+value as in the previous reading, causing the monotonic value to be
+incremented too often.
+
+Drivers should take the responsibility to avoid too often reads. That
+can be done using two approaches:
+
+if the driver have a bit that indicates when a collected data is ready
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Driver should check such bit before making the statistics available.
+
+An example of such behavior can be found at this code snippet (adapted
+from mb86a20s driver's logic)::
+
+ static int foo_get_pre_ber(struct dvb_frontend *fe)
+ {
+ struct foo_state *state = fe->demodulator_priv;
+ struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+ int rc, bit_error;
+
+ /* Check if the BER measures are already available */
+ rc = foo_read_u8(state, 0x54);
+ if (rc < 0)
+ return rc;
+
+ if (!rc)
+ return 0;
+
+ /* Read Bit Error Count */
+ bit_error = foo_read_u32(state, 0x55);
+ if (bit_error < 0)
+ return bit_error;
+
+ /* Read Total Bit Count */
+ rc = foo_read_u32(state, 0x51);
+ if (rc < 0)
+ return rc;
+
+ c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_error.stat[0].uvalue += bit_error;
+ c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_count.stat[0].uvalue += rc;
+
+ return 0;
+ }
+
+If the driver doesn't provide a statistics available check bit
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+A few devices, however, may not provide a way to check if the stats are
+available (or the way to check it is unknown). They may not even provide
+a way to directly read the total number of bits or blocks.
+
+On those devices, the driver need to ensure that it won't be reading from
+the register too often and/or estimate the total number of bits/blocks.
+
+On such drivers, a typical routine to get statistics would be like
+(adapted from dib8000 driver's logic)::
+
+ struct foo_state {
+ /* ... */
+
+ unsigned long per_jiffies_stats;
+ }
+
+ static int foo_get_pre_ber(struct dvb_frontend *fe)
+ {
+ struct foo_state *state = fe->demodulator_priv;
+ struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+ int rc, bit_error;
+ u64 bits;
+
+ /* Check if time for stats was elapsed */
+ if (!time_after(jiffies, state->per_jiffies_stats))
+ return 0;
+
+ /* Next stat should be collected in 1000 ms */
+ state->per_jiffies_stats = jiffies + msecs_to_jiffies(1000);
+
+ /* Read Bit Error Count */
+ bit_error = foo_read_u32(state, 0x55);
+ if (bit_error < 0)
+ return bit_error;
+
+ /*
+ * On this particular frontend, there's no register that
+ * would provide the number of bits per 1000ms sample. So,
+ * some function would calculate it based on DTV properties
+ */
+ bits = get_number_of_bits_per_1000ms(fe);
+
+ c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_error.stat[0].uvalue += bit_error;
+ c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
+ c->pre_bit_count.stat[0].uvalue += bits;
+
+ return 0;
+ }
+
+Please notice that, on both cases, we're getting the statistics using the
+:c:type:`dvb_frontend_ops` ``.read_status`` callback. The rationale is that
+the frontend core will automatically call this function periodically
+(usually, 3 times per second, when the frontend is locked).
+
+That warrants that we won't miss to collect a counter and increment the
+monotonic stats at the right time.

+Multicopy atomicity is a deeply intuitive notion about ordering that is
+not always provided by real computer systems, namely that a given store
+becomes visible at the same time to all CPUs, or, alternatively, that all
+CPUs agree on the order in which all stores become visible. However,
+support of full multicopy atomicity would rule out valuable hardware
+optimizations, so a weaker form called ``other multicopy atomicity''
+instead guarantees only that a given store becomes visible at the same
+time to all -other- CPUs. The remainder of this document discusses this
+weaker form, but for brevity will call it simply ``multicopy atomicity''.
+
+The following example demonstrates multicopy atomicity:
CPU 1 CPU 2 CPU 3
======================= ======================= =======================
{ X = 0, Y = 0 }
- STORE X=1 LOAD X STORE Y=1
- <general barrier> <general barrier>
- LOAD Y LOAD X
-
-Suppose that CPU 2's load from X returns 1 and its load from Y returns 0.
-This indicates that CPU 2's load from X in some sense follows CPU 1's
-store to X and that CPU 2's load from Y in some sense preceded CPU 3's
-store to Y. The question is then "Can CPU 3's load from X return 0?"
-
-Because CPU 2's load from X in some sense came after CPU 1's store, it
+ STORE X=1 r1=LOAD X (reads 1) LOAD Y (reads 1)
+ <general barrier> <read barrier>
+ STORE Y=r1 LOAD X
+
+Suppose that CPU 2's load from X returns 1, which it then stores to Y,
+and CPU 3's load from Y returns 1. This indicates that CPU 1's store
+to X precedes CPU 2's load from X and that CPU 2's store to Y precedes
+CPU 3's load from Y. In addition, the memory barriers guarantee that
+CPU 2 executes its load before its store, and CPU 3 loads from Y before
+it loads from X. The question is then "Can CPU 3's load from X return 0?"
+
+Because CPU 3's load from X in some sense comes after CPU 2's load, it
is natural to expect that CPU 3's load from X must therefore return 1.
-This expectation is an example of transitivity: if a load executing on
-CPU A follows a load from the same variable executing on CPU B, then
-CPU A's load must either return the same value that CPU B's load did,
-or must return some later value.
-
-In the Linux kernel, use of general memory barriers guarantees
-transitivity. Therefore, in the above example, if CPU 2's load from X
-returns 1 and its load from Y returns 0, then CPU 3's load from X must
-also return 1.
-
-However, transitivity is -not- guaranteed for read or write barriers.
-For example, suppose that CPU 2's general barrier in the above example
-is changed to a read barrier as shown below:
+This expectation follows from multicopy atomicity: if a load executing
+on CPU B follows a load from the same variable executing on CPU A (and
+CPU A did not originally store the value which it read), then on
+multicopy-atomic systems, CPU B's load must return either the same value
+that CPU A's load did or some later value. However, the Linux kernel
+does not require systems to be multicopy atomic.
+
+The use of a general memory barrier in the example above compensates
+for any lack of multicopy atomicity. In the example, if CPU 2's load
+from X returns 1 and CPU 3's load from Y returns 1, then CPU 3's load
+from X must indeed also return 1.
+
+However, dependencies, read barriers, and write barriers are not always
+able to compensate for non-multicopy atomicity. For example, suppose
+that CPU 2's general barrier is removed from the above example, leaving
+only the data dependency shown below:
CPU 1 CPU 2 CPU 3
======================= ======================= =======================
{ X = 0, Y = 0 }
- STORE X=1 LOAD X STORE Y=1
- <read barrier> <general barrier>
- LOAD Y LOAD X
-
-This substitution destroys transitivity: in this example, it is perfectly
-legal for CPU 2's load from X to return 1, its load from Y to return 0,
-and CPU 3's load from X to return 0.
-
-The key point is that although CPU 2's read barrier orders its pair
-of loads, it does not guarantee to order CPU 1's store. Therefore, if
-this example runs on a system where CPUs 1 and 2 share a store buffer
-or a level of cache, CPU 2 might have early access to CPU 1's writes.
-General barriers are therefore required to ensure that all CPUs agree
-on the combined order of CPU 1's and CPU 2's accesses.
-
-General barriers provide "global transitivity", so that all CPUs will
-agree on the order of operations. In contrast, a chain of release-acquire
-pairs provides only "local transitivity", so that only those CPUs on
-the chain are guaranteed to agree on the combined order of the accesses.
-For example, switching to C code in deference to Herman Hollerith:
+ STORE X=1 r1=LOAD X (reads 1) LOAD Y (reads 1)
+ <data dependency> <read barrier>
+ STORE Y=r1 LOAD X (reads 0)
+
+This substitution allows non-multicopy atomicity to run rampant: in
+this example, it is perfectly legal for CPU 2's load from X to return 1,
+CPU 3's load from Y to return 1, and its load from X to return 0.
+
+The key point is that although CPU 2's data dependency orders its load
+and store, it does not guarantee to order CPU 1's store. Thus, if this
+example runs on a non-multicopy-atomic system where CPUs 1 and 2 share a
+store buffer or a level of cache, CPU 2 might have early access to CPU 1's
+writes. General barriers are therefore required to ensure that all CPUs
+agree on the combined order of multiple accesses.
+
+General barriers can compensate not only for non-multicopy atomicity,
+but can also generate additional ordering that can ensure that -all-
+CPUs will perceive the same order of -all- operations. In contrast, a
+chain of release-acquire pairs do not provide this additional ordering,

+
+The driver is implemented as a DSA driver, see
+Documentation/networking/dsa/dsa.txt.
+
+See Documentation/devicetree/bindings/net/dsa/lan9303.txt for device tree

+
+The LAN9303 can be managed both via MDIO and I2C, both supported by this driver.
+
+At startup the driver configures the device to provide two separate network
+interfaces (which is the default state of a DSA device). Due to HW limitations,
+no HW MAC learning takes place in this mode.
+
+When both user ports are joined to the same bridge, the normal HW MAC learning
+is enabled. This means that unicast traffic is forwarded in HW. Broadcast and
+multicast is flooded in HW. STP is also supported in this mode. The driver
+support fdb/mdb operations as well, meaning IGMP snooping is supported.
+
+If one of the user ports leave the bridge, the ports goes back to the initial

+=== Local GTP-U entity and tunnel identification ===
+
+GTP-U uses UDP for transporting PDU's. The receiving UDP port is 2152
+for GTPv1-U and 3386 for GTPv0-U.
+
+There is only one GTP-U entity (and therefor SGSN/GGSN/S-GW/PDN-GW
+instance) per IP address. Tunnel Endpoint Identifier (TEID) are unique
+per GTP-U entity.
+
+A specific tunnel is only defined by the destination entity. Since the
+destination port is constant, only the destination IP and TEID define
+a tunnel. The source IP and Port have no meaning for the tunnel.
+
+Therefore:
+
+ * when sending, the remote entity is defined by the remote IP and
+ the tunnel endpoint id. The source IP and port have no meaning and
+ can be changed at any time.
+
+ * when receiving the local entity is defined by the local
+ destination IP and the tunnel endpoint id. The source IP and port
+ have no meaning and can change at any time.
+
+[3GPP TS 29.281] Section 4.3.0 defines this so:
+
+> The TEID in the GTP-U header is used to de-multiplex traffic
+> incoming from remote tunnel endpoints so that it is delivered to the
+> User plane entities in a way that allows multiplexing of different
+> users, different packet protocols and different QoS levels.
+> Therefore no two remote GTP-U endpoints shall send traffic to a
+> GTP-U protocol entity using the same TEID value except
+> for data forwarding as part of mobility procedures.
+
+The definition above only defines that two remote GTP-U endpoints
+*should not* send to the same TEID, it *does not* forbid or exclude
+such a scenario. In fact, the mentioned mobility procedures make it
+necessary that the GTP-U entity accepts traffic for TEIDs from
+multiple or unknown peers.
+
+Therefore, the receiving side identifies tunnels exclusively based on
+TEIDs, not based on the source IP!
+
+== APN vs. Network Device ==
+
+The GTP-U driver creates a Linux network device for each Gi/SGi
+interface.
+
+[3GPP TS 29.281] calls the Gi/SGi reference point an interface. This
+may lead to the impression that the GGSN/P-GW can have only one such
+interface.
+
+Correct is that the Gi/SGi reference point defines the interworking
+between +the 3GPP packet domain (PDN) based on GTP-U tunnel and IP
+based networks.
+
+There is no provision in any of the 3GPP documents that limits the
+number of Gi/SGi interfaces implemented by a GGSN/P-GW.
+
+[3GPP TS 29.061] Section 11.3 makes it clear that the selection of a
+specific Gi/SGi interfaces is made through the Access Point Name

+Identifier Locator Addressing (ILA)
+
+
+Introduction
+============
+
+Identifier-locator addressing (ILA) is a technique used with IPv6 that
+differentiates between location and identity of a network node. Part of an
+address expresses the immutable identity of the node, and another part
+indicates the location of the node which can be dynamic. Identifier-locator
+addressing can be used to efficiently implement overlay networks for
+network virtualization as well as solutions for use cases in mobility.
+
+ILA can be thought of as means to implement an overlay network without
+encapsulation. This is accomplished by performing network address
+translation on destination addresses as a packet traverses a network. To
+the network, an ILA translated packet appears to be no different than any
+other IPv6 packet. For instance, if the transport protocol is TCP then an
+ILA translated packet looks like just another TCP/IPv6 packet. The
+advantage of this is that ILA is transparent to the network so that
+optimizations in the network, such as ECMP, RSS, GRO, GSO, etc., just work.
+
+The ILA protocol is described in Internet-Draft draft-herbert-intarea-ila.
+
+
+ILA terminology
+===============
+
+ - Identifier A number that identifies an addressable node in the network
+ independent of its location. ILA identifiers are sixty-four
+ bit values.
+
+ - Locator A network prefix that routes to a physical host. Locators
+ provide the topological location of an addressed node. ILA
+ locators are sixty-four bit prefixes.
+
+ - ILA mapping
+ A mapping of an ILA identifier to a locator (or to a
+ locator and meta data). An ILA domain maintains a database
+ that contains mappings for all destinations in the domain.
+
+ - SIR address
+ An IPv6 address composed of a SIR prefix (upper sixty-
+ four bits) and an identifier (lower sixty-four bits).
+ SIR addresses are visible to applications and provide a
+ means for them to address nodes independent of their
+ location.
+
+ - ILA address
+ An IPv6 address composed of a locator (upper sixty-four
+ bits) and an identifier (low order sixty-four bits). ILA
+ addresses are never visible to an application.
+
+ - ILA host An end host that is capable of performing ILA translations
+ on transmit or receive.
+
+ - ILA router A network node that performs ILA translation and forwarding
+ of translated packets.
+
+ - ILA forwarding cache
+ A type of ILA router that only maintains a working set
+ cache of mappings.
+
+ - ILA node A network node capable of performing ILA translations. This
+ can be an ILA router, ILA forwarding cache, or ILA host.
+
+
+Operation
+=========
+
+There are two fundamental operations with ILA:
+
+ - Translate a SIR address to an ILA address. This is performed on ingress
+ to an ILA overlay.
+
+ - Translate an ILA address to a SIR address. This is performed on egress
+ from the ILA overlay.
+
+ILA can be deployed either on end hosts or intermediate devices in the
+network; these are provided by "ILA hosts" and "ILA routers" respectively.
+Configuration and datapath for these two points of deployment is somewhat
+different.
+
+The diagram below illustrates the flow of packets through ILA as well
+as showing ILA hosts and routers.

+
+Transport checksum handling
+===========================
+
+When an address is translated by ILA, an encapsulated transport checksum
+that includes the translated address in a pseudo header may be rendered
+incorrect on the wire. This is a problem for intermediate devices,
+including checksum offload in NICs, that process the checksum. There are
+three options to deal with this:
+
+- no action Allow the checksum to be incorrect on the wire. Before
+ a receiver verifies a checksum the ILA to SIR address
+ translation must be done.
+
+- adjust transport checksum
+ When ILA translation is performed the packet is parsed
+ and if a transport layer checksum is found then it is
+ adjusted to reflect the correct checksum per the
+ translated address.
+
+- checksum neutral mapping
+ When an address is translated the difference can be offset
+ elsewhere in a part of the packet that is covered by the
+ the checksum. The low order sixteen bits of the identifier
+ are used. This method is preferred since it doesn't require
+ parsing a packet beyond the IP header and in most cases the
+ adjustment can be precomputed and saved with the mapping.
+
+Note that the checksum neutral adjustment affects the low order sixteen
+bits of the identifier. When ILA to SIR address translation is done on
+egress the low order bits are restored to the original value which
+restores the identifier as it was originally sent.
+
+
+Identifier types
+================
+
+ILA defines different types of identifiers for different use cases.
+
+The defined types are:
+
+ 0: interface identifier
+
+ 1: locally unique identifier
+
+ 2: virtual networking identifier for IPv4 address
+
+ 3: virtual networking identifier for IPv6 unicast address
+
+ 4: virtual networking identifier for IPv6 multicast address
+
+ 5: non-local address identifier
+
+In the current implementation of kernel ILA only locally unique identifiers
+(LUID) are supported. LUID allows for a generic, unformatted 64 bit
+identifier.
+
+
+Identifier formats
+==================
+
+Kernel ILA supports two optional fields in an identifier for formatting:
+"C-bit" and "identifier type". The presence of these fields is determined
+by configuration as demonstrated below.
+
+If the identifier type is present it occupies the three highest order
+bits of an identifier. The possible values are given in the above list.
+
+If the C-bit is present, this is used as an indication that checksum
+neutral mapping has been done. The C-bit can only be set in an
+ILA address, never a SIR address.
+
+In the simplest format the identifier types, C-bit, and checksum
+adjustment value are not present so an identifier is considered an
+unstructured sixty-four bit value.
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Identifier |
+ + +
+ | |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+The checksum neutral adjustment may be configured to always be
+present using neutral-map-auto. In this case there is no C-bit, but the
+checksum adjustment is in the low order 16 bits. The identifier is
+still sixty-four bits.
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Identifier |
+ | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | | Checksum-neutral adjustment |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+The C-bit may used to explicitly indicate that checksum neutral
+mapping has been applied to an ILA address. The format is:
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | |C| Identifier |
+ | +-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | | Checksum-neutral adjustment |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+The identifier type field may be present to indicate the identifier
+type. If it is not present then the type is inferred based on mapping
+configuration. The checksum neutral adjustment may automatically
+used with the identifier type as illustrated below.
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Type| Identifier |
+ +-+-+-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | | Checksum-neutral adjustment |
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+
+If the identifier type and the C-bit can be present simultaneously so
+the identifier format would be:
+
+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | Type|C| Identifier |
+ +-+-+-+-+ +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+ | | Checksum-neutral adjustment |

+
+Configuration
+=============
+
+There are two methods to configure ILA mappings. One is by using LWT routes
+and the other is ila_xlat (called from NFHOOK PREROUTING hook). ila_xlat
+is intended to be used in the receive path for ILA hosts .
+
+An ILA router has also been implemented in XDP. Description of that is
+outside the scope of this document.
+
+The usage of for ILA LWT routes is:
+
+ip route add DEST/128 encap ila LOC csum-mode MODE ident-type TYPE via ADDR
+
+Destination (DEST) can either be a SIR address (for an ILA host or ingress
+ILA router) or an ILA address (egress ILA router). LOC is the sixty-four
+bit locator (with format W:X:Y:Z) that overwrites the upper sixty-four
+bits of the destination address. Checksum MODE is one of "no-action",
+"adj-transport", "neutral-map", and "neutral-map-auto". If neutral-map is
+set then the C-bit will be present. Identifier TYPE one of "luid" or
+"use-format." In the case of use-format, the identifier type field is
+present and the effective type is taken from that.
+
+The usage of ila_xlat is:
+
+ip ila add loc_match MATCH loc LOC csum-mode MODE ident-type TYPE
+
+MATCH indicates the incoming locator that must be matched to apply
+a the translaiton. LOC is the locator that overwrites the upper
+sixty-four bits of the destination address. MODE and TYPE have the
+same meanings as described above.
+
+
+Some examples
+=============
+
+# Configure an ILA route that uses checksum neutral mapping as well
+# as type field. Note that the type field is set in the SIR address
+# (the 2000 implies type is 1 which is LUID).
+ip route add 3333:0:0:1:2000:0:1:87/128 encap ila 2001:0:87:0 \
+ csum-mode neutral-map ident-type use-format
+
+# Configure an ILA LWT route that uses auto checksum neutral mapping
+# (no C-bit) and configure identifier type to be LUID so that the
+# identifier type field will not be present.
+ip route add 3333:0:0:1:2000:0:2:87/128 encap ila 2001:0:87:1 \
+ csum-mode neutral-map-auto ident-type luid
+
+ila_xlat configuration
+
+# Configure an ILA to SIR mapping that matches a locator and overwrites
+# it with a SIR address (3333:0:0:1 in this example). The C-bit and
+# identifier field are used.
+ip ila add loc_match 2001:0:119:0 loc 3333:0:0:1 \
+ csum-mode neutral-map-auto ident-type use-format
+
+# Configure an ILA to SIR mapping where checksum neutral is automatically
+# set without the C-bit and the identifier type is configured to be LUID
+# so that the identifier type field is not present.
+ip ila add loc_match 2001:0:119:0 loc 3333:0:0:1 \
+ csum-mode neutral-map-auto ident-type use-format

+HiSilicon SoC uncore Performance Monitoring Unit (PMU)
+======================================================
+The HiSilicon SoC chip includes various independent system device PMUs
+such as L3 cache (L3C), Hydra Home Agent (HHA) and DDRC. These PMUs are
+independent and have hardware logic to gather statistics and performance
+information.
+
+The HiSilicon SoC encapsulates multiple CPU and IO dies. Each CPU cluster
+(CCL) is made up of 4 cpu cores sharing one L3 cache; each CPU die is
+called Super CPU cluster (SCCL) and is made up of 6 CCLs. Each SCCL has
+two HHAs (0 - 1) and four DDRCs (0 - 3), respectively.
+
+HiSilicon SoC uncore PMU driver
+---------------------------------------
+Each device PMU has separate registers for event counting, control and
+interrupt, and the PMU driver shall register perf PMU drivers like L3C,
+HHA and DDRC etc. The available events and configuration options shall
+be described in the sysfs, see :
+/sys/devices/hisi_sccl{X}_<l3c{Y}/hha{Y}/ddrc{Y}>/, or
+/sys/bus/event_source/devices/hisi_sccl{X}_<l3c{Y}/hha{Y}/ddrc{Y}>.
+The "perf list" command shall list the available events from sysfs.
+
+Each L3C, HHA and DDRC is registered as a separate PMU with perf. The PMU
+name will appear in event listing as hisi_sccl<sccl-id>_module<index-id>.
+where "sccl-id" is the identifier of the SCCL and "index-id" is the index of
+module.
+e.g. hisi_sccl3_l3c0/rd_hit_cpipe is READ_HIT_CPIPE event of L3C index #0 in
+SCCL ID #3.
+e.g. hisi_sccl1_hha0/rx_operations is RX_OPERATIONS event of HHA index #0 in
+SCCL ID #1.
+
+The driver also provides a "cpumask" sysfs attribute, which shows the CPU core
+ID used to count the uncore PMU event.
+
+Example usage of perf:
+$# perf list
+hisi_sccl3_l3c0/rd_hit_cpipe/ [kernel PMU event]
+------------------------------------------
+hisi_sccl3_l3c0/wr_hit_cpipe/ [kernel PMU event]
+------------------------------------------
+hisi_sccl1_l3c0/rd_hit_cpipe/ [kernel PMU event]
+------------------------------------------
+hisi_sccl1_l3c0/wr_hit_cpipe/ [kernel PMU event]
+------------------------------------------
+
+$# perf stat -a -e hisi_sccl3_l3c0/rd_hit_cpipe/ sleep 5
+$# perf stat -a -e hisi_sccl3_l3c0/config=0x02/ sleep 5
+
+The current driver does not support sampling. So "perf record" is unsupported.
+Also attach to a task is unsupported as the events are all uncore.
+
+Note: Please contact the maintainer for a complete list of events supported for
+the PMU devices in the SoC and its information if needed.

+3.1.19. Driver Flags for Power Management
+
+The PM core allows device drivers to set flags that influence the handling of
+power management for the devices by the core itself and by middle layer code
+including the PCI bus type. The flags should be set once at the driver probe
+time with the help of the dev_pm_set_driver_flags() function and they should not
+be updated directly afterwards.
+
+The DPM_FLAG_NEVER_SKIP flag prevents the PM core from using the direct-complete
+mechanism allowing device suspend/resume callbacks to be skipped if the device
+is in runtime suspend when the system suspend starts. That also affects all of
+the ancestors of the device, so this flag should only be used if absolutely
+necessary.
+
+The DPM_FLAG_SMART_PREPARE flag instructs the PCI bus type to only return a
+positive value from pci_pm_prepare() if the ->prepare callback provided by the
+driver of the device returns a positive value. That allows the driver to opt
+out from using the direct-complete mechanism dynamically.
+
+The DPM_FLAG_SMART_SUSPEND flag tells the PCI bus type that from the driver's
+perspective the device can be safely left in runtime suspend during system
+suspend. That causes pci_pm_suspend(), pci_pm_freeze() and pci_pm_poweroff()
+to skip resuming the device from runtime suspend unless there are PCI-specific
+reasons for doing that. Also, it causes pci_pm_suspend_late/noirq(),
+pci_pm_freeze_late/noirq() and pci_pm_poweroff_late/noirq() to return early
+if the device remains in runtime suspend in the beginning of the "late" phase
+of the system-wide transition under way. Moreover, if the device is in
+runtime suspend in pci_pm_resume_noirq() or pci_pm_restore_noirq(), its runtime
+power management status will be changed to "active" (as it is going to be put
+into D0 going forward), but if it is in runtime suspend in pci_pm_thaw_noirq(),
+the function will set the power.direct_complete flag for it (to make the PM core
+skip the subsequent "thaw" callbacks for it) and return.

+Position Statement on Linux Kernel Modules
+==========================================
+
+
+We, the undersigned Linux kernel developers, consider any closed-source
+Linux kernel module or driver to be harmful and undesirable. We have
+repeatedly found them to be detrimental to Linux users, businesses, and
+the greater Linux ecosystem. Such modules negate the openness,
+stability, flexibility, and maintainability of the Linux development
+model and shut their users off from the expertise of the Linux
+community. Vendors that provide closed-source kernel modules force their
+customers to give up key Linux advantages or choose new vendors.
+Therefore, in order to take full advantage of the cost savings and
+shared support benefits open source has to offer, we urge vendors to
+adopt a policy of supporting their customers on Linux with open-source
+kernel code.
+
+We speak only for ourselves, and not for any company we might work for
+today, have in the past, or will in the future.

-ALS-007/ALS-100/ALS-200 based sound cards
-=========================================
-
-Support for sound cards based around the Avance Logic
-ALS-007/ALS-100/ALS-200 chip is included. These chips are a single
-chip PnP sound solution which is mostly hardware compatible with the
-Sound Blaster 16 card, with most differences occurring in the use of
-the mixer registers. For this reason the ALS code is integrated
-as part of the Sound Blaster 16 driver (adding only 800 bytes to the
-SB16 driver).
-
-To use an ALS sound card under Linux, enable the following options as
-modules in the sound configuration section of the kernel config:
- - 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support
- - FM synthesizer (YM3812/OPL-3) support
- - standalone MPU401 support may be required for some cards; for the
- ALS-007, when using isapnptools, it is required
-Since the ALS-007/100/200 are PnP cards, ISAPnP support should probably be
-compiled in. If kernel level PnP support is not included, isapnptools will
-be required to configure the card before the sound modules are loaded.
-
-When using kernel level ISAPnP, the kernel should correctly identify and
-configure all resources required by the card when the "sb" module is
-inserted. Note that the ALS-007 does not have a 16 bit DMA channel and that
-the MPU401 interface on this card uses a different interrupt to the audio
-section. This should all be correctly configured by the kernel; if problems
-with the MPU401 interface surface, try using the standalone MPU401 module,
-passing "0" as the "sb" module's "mpu_io" module parameter to prevent the
-soundblaster driver attempting to register the MPU401 itself. The onboard
-synth device can be accessed using the "opl3" module.
-
-If isapnptools is used to wake up the sound card (as in 2.2.x), the settings
-of the card's resources should be passed to the kernel modules ("sb", "opl3"
-and "mpu401") using the module parameters. When configuring an ALS-007, be
-sure to specify different IRQs for the audio and MPU401 sections - this card
-requires they be different. For "sb", "io", "irq" and "dma" should be set
-to the same values used to configure the audio section of the card with
-isapnp. "dma16" should be explicitly set to "-1" for an ALS-007 since this
-card does not have a 16 bit dma channel; if not specified the kernel will
-default to using channel 5 anyway which will cause audio not to work.
-"mpu_io" should be set to 0. The "io" parameter of the "opl3" module should
-also agree with the setting used by isapnp. To get the MPU401 interface
-working on an ALS-007 card, the "mpu401" module will be required since this
-card uses separate IRQs for the audio and MPU401 sections and there is no
-parameter available to pass a different IRQ to the "sb" driver (whose
-inbuilt MPU401 driver would otherwise be fine). Insert the mpu401 module
-passing appropriate values using the "io" and "irq" parameters.
-
-The resulting sound driver will provide the following capabilities:
- - 8 and 16 bit audio playback
- - 8 and 16 bit audio recording
- - Software selection of record source (line in, CD, FM, mic, master)
- - Record and playback of midi data via the external MPU-401
- - Playback of midi data using inbuilt FM synthesizer
- - Control of the ALS-007 mixer via any OSS-compatible mixer programs.
- Controls available are Master (L&R), Line in (L&R), CD (L&R),
- DSP/PCM/audio out (L&R), FM (L&R) and Mic in (mono).

-Driver
-------
-
-Information about Audio Excel DSP 16 driver can be found in the source
-file aedsp16.c
-Please, read the head of the source before using it. It contain useful
-information.
-
-Configuration
--------------
-
-The Audio Excel configuration, is now done with the standard Linux setup.
-You have to configure the sound card (Sound Blaster or Microsoft Sound System)
-and, if you want it, the Roland MPU-401 (do not use the Sound Blaster MPU-401,
-SB-MPU401) in the main driver menu. Activate the lowlevel drivers then select
-the Audio Excel hardware that you want to initialize. Check the IRQ/DMA/MIRQ
-of the Audio Excel initialization: it must be the same as the SBPRO (or MSS)
-setup. If the parameters are different, correct it.
-I you own a Gallant's audio card based on SC-6600, activate the SC-6600 support.
-If you want to change the configuration of the sound board, be sure to
-check off all the configuration items before re-configure it.
-
-Module parameters
------------------
-To use this driver as a module, you must configure some module parameters, to
-set up I/O addresses, IRQ lines and DMA channels. Some parameters are
-mandatory while some others are optional. Here a list of parameters you can
-use with this module:
-
-Name Description
-==== ===========
-MANDATORY
-io I/O base address (0x220 or 0x240)
-irq irq line (5, 7, 9, 10 or 11)
-dma dma channel (0, 1 or 3)
-
-OPTIONAL
-mss_base I/O base address for activate MSS mode (default SBPRO)
- (0x530 or 0xE80)
-mpu_base I/O base address for activate MPU-401 mode
- (0x300, 0x310, 0x320 or 0x330)
-mpu_irq MPU-401 irq line (5, 7, 9, 10 or 0)
-
-A configuration file in /etc/modprobe.d/ directory will have lines like this:
-
-options opl3 io=0x388
-options ad1848 io=0x530 irq=11 dma=3
-options aedsp16 io=0x220 irq=11 dma=3 mss_base=0x530
-
-Where the aedsp16 options are the options for this driver while opl3 and
-ad1848 are the corresponding options for the MSS and OPL3 modules.
-
-Loading MSS and OPL3 needs to pre load the aedsp16 module to set up correctly
-the sound card. Installation dependencies must be written in configuration
-files under /etc/modprobe.d/ directory:
-
-softdep ad1848 pre: aedsp16
-softdep opl3 pre: aedsp16
-
-Then you must load the sound modules stack in this order:
-sound -> aedsp16 -> [ ad1848, opl3 ]
-
-With the above configuration, loading ad1848 or opl3 modules, will
-automatically load all the sound stack.
-
-Sound cards supported
----------------------
-This driver supports the SC-6000 and SC-6600 based Gallant's sound card.
-It don't support the Audio Excel DSP 16 III (try the SC-6600 code).
-I'm working on the III version of the card: if someone have useful
-information about it, please let me know.
-For all the non-supported audio cards, you have to boot MS-DOS (or WIN95)
-activating the audio card with the MS-DOS device driver, then you have to
-<ctrl>-<alt>-<del> and boot Linux.
-Follow these steps:
-
-1) Compile Linux kernel with standard sound driver, using the emulation
- you want, with the parameters of your audio card,
- e.g. Microsoft Sound System irq10 dma3
-2) Install your new kernel as the default boot kernel.
-3) Boot MS-DOS and configure the audio card with the boot time device
- driver, for MSS irq10 dma3 in our example.
-4) <ctrl>-<alt>-<del> and boot Linux. This will maintain the DOS configuration
- and will boot the new kernel with sound driver. The sound driver will find
- the audio card and will recognize and attach it.

-( Be sure to read Documentation/sound/oss/SoundPro too )
-
-
-This adapter is now directly supported by the sb driver.
-
- The only thing you have to do is to compile the kernel sound

-as shown below.
-
-
-CONFIG_SOUND=m

- for MPU401 support.
-
-
-(I suggest you to use "make menuconfig" or "make xconfig"
- for a more comfortable configuration editing)
-
-
-
-Then you can do
-
- modprobe sb
-
-and everything will be (hopefully) configured.

-Documentation for the ESS AudioDrive chips
-
-In 2.4 kernels the SoundBlaster driver not only tries to detect an ESS chip, it
-tries to detect the type of ESS chip too. The correct detection of the chip
-doesn't always succeed however, so unless you use the kernel isapnp facilities
-(and you chip is pnp capable) the default behaviour is 2.0 behaviour which
-means: only detect ES688 and ES1688.
-
-All ESS chips now have a recording level setting. This is a need-to-have for
-people who want to use their ESS for recording sound.
-
-Every chip that's detected as a later-than-es1688 chip has a 6 bits logarithmic
-master volume control.
-
-Every chip that's detected as a ES1887 now has Full Duplex support. Made a
-little testprogram that shows that is works, haven't seen a real program that
-needs this however.
-
-For ESS chips an additional parameter "esstype" can be specified. This controls
-the (auto) detection of the ESS chips. It can have 3 kinds of values:
-
--1 Act like 2.0 kernels: only detect ES688 or ES1688.
-0 Try to auto-detect the chip (may fail for ES1688)
-688 The chip will be treated as ES688
-1688 ,, ,, ,, ,, ,, ,, ES1688
-1868 ,, ,, ,, ,, ,, ,, ES1868
-1869 ,, ,, ,, ,, ,, ,, ES1869
-1788 ,, ,, ,, ,, ,, ,, ES1788
-1887 ,, ,, ,, ,, ,, ,, ES1887
-1888 ,, ,, ,, ,, ,, ,, ES1888
-
-Because Full Duplex is supported for ES1887 you can specify a second DMA
-channel by specifying module parameter dma16. It can be one of: 0, 1, 3 or 5.

-Documentation for the ESS1868F AudioDrive PnP sound card
-
-The ESS1868 sound card is a PnP ESS1688-compatible 16-bit sound card.
-
-It should be automatically detected by the Linux Kernel isapnp support when you
-load the sb.o module. Otherwise you should take care of:
-
- * The ESS1868 does not allow use of a 16-bit DMA, thus DMA 0, 1, 2, and 3
- may only be used.
-
- * isapnptools version 1.14 does work with ESS1868. Earlier versions might
- not.
-
- * Sound support MUST be compiled as MODULES, not statically linked
- into the kernel.
-
-
-NOTE: this is only needed when not using the kernel isapnp support!
-
-For configuring the sound card's I/O addresses, IRQ and DMA, here is a
-sample copy of the isapnp.conf directives regarding the ESS1868:
-
-(CONFIGURE ESS1868/-1 (LD 1
-(IO 0 (BASE 0x0220))
-(IO 1 (BASE 0x0388))
-(IO 2 (BASE 0x0330))
-(DMA 0 (CHANNEL 1))
-(INT 0 (IRQ 5 (MODE +E)))
-(ACT Y)
-))
-
-(for a full working isapnp.conf file, remember the
-(ISOLATE)
-(IDENTIFY *)
-at the beginning and the
-(WAITFORKEY)
-at the end.)
-
-In this setup, the main card I/O is 0x0220, FM synthesizer is 0x0388, and
-the MPU-401 MIDI port is located at 0x0330. IRQ is IRQ 5, DMA is channel 1.
-
-After configuring the sound card via isapnp, to use the card you must load
-the sound modules with the proper I/O information. Here is my setup:
-
-# ESS1868F AudioDrive initialization
-
-/sbin/modprobe sound
-/sbin/insmod uart401
-/sbin/insmod sb io=0x220 irq=5 dma=1 dma16=-1
-/sbin/insmod mpu401 io=0x330
-/sbin/insmod opl3 io=0x388
-/sbin/insmod v_midi
-
-opl3 is the FM synthesizer
-/sbin/insmod opl3 io=0x388

-
-
-Modular Sound Drivers:
-======================
-
-Thanks to the GREAT work by Alan Cox (alan@lxorguk.ukuu.org.uk),
-
-[And Oleg Drokin, Thomas Sailer, Andrew Veliath and more than a few
- others - not to mention Hannu's original code being designed well
- enough to cope with that kind of chopping up](Alan)
-
-the standard Linux kernels support a modular sound driver. From
-Alan's comments in linux/drivers/sound/README.FIRST:
-
- The modular sound driver patches were funded by Red Hat Software
- (www.redhat.com). The sound driver here is thus a modified version of
- Hannu's code. Please bear that in mind when considering the appropriate
- forums for bug reporting.
-
-The modular sound drivers may be loaded via insmod or modprobe.
-To support all the various sound modules, there are two general
-support modules that must be loaded first:
-
- soundcore.o: Top level handler for the sound system, provides
- a set of functions for registration of devices
- by type.
-
- sound.o: Common sound functions required by all modules.
-
-For the specific sound modules (e.g., sb.o for the Soundblaster),
-read the documentation on that module to determine what options
-are available, for example IRQ, address, DMA.
-
-Warning, the options for different cards sometime use different names
-for the same or a similar feature (dma1= versus dma16=). As a last
-resort, inspect the code (search for module_param).
-
-Notes:
-
-1. There is a new OpenSource sound driver called ALSA which is
- currently under development: http://www.alsa-project.org/
- The ALSA drivers support some newer hardware that may not
- be supported by this sound driver and also provide some
- additional features.
-
-2. The commercial OSS driver may be obtained from the site:
- http://www.opensound.com. This may be used for cards that
- are unsupported by the kernel driver, or may be used
- by other operating systems.
-
-3. The enlightenment sound daemon may be used for playing
- multiple sounds at the same time via a single card, eliminating
- some of the requirements for multiple sound card systems. For
- more information, see: http://www.tux.org/~ricdude/EsounD.html
- The "esd" program may be used with the real-player and mpeg
- players like mpg123 and x11amp. The newer real-player
- and some games even include built-in support for ESD!
-
-
-Building the Modules:
-=====================
-
-This document does not provide full details on building the
-kernel, etc. The notes below apply only to making the kernel
-sound modules. If this conflicts with the kernel's README,
-the README takes precedence.
-
-1. To make the kernel sound modules, cd to your /usr/src/linux
- directory (typically) and type make config, make menuconfig,
- or make xconfig (to start the command line, dialog, or x-based
- configuration tool).
-
-2. Select the Sound option and a dialog will be displayed.
-
-3. Select M (module) for "Sound card support".
-
-4. Select your sound driver(s) as a module. For ProAudio, Sound
- Blaster, etc., select M (module) for OSS sound modules.
- [thanks to Marvin Stodolsky <stodolsk@erols.com>]A
-
-5. Make the kernel (e.g., make bzImage), and install the kernel.
-
-6. Make the modules and install them (make modules; make modules_install).
-
-Note, for 2.5.x kernels, make sure you have the newer module-init-tools
-installed or modules will not be loaded properly. 2.5.x requires an
-updated module-init-tools.
-
-
-Plug and Play (PnP:
-===================
-
-If the sound card is an ISA PnP card, isapnp may be used
-to configure the card. See the file isapnp.txt in the
-directory one level up (e.g., /usr/src/linux/Documentation).
-
-Also the 2.4.x kernels provide PnP capabilities, see the
-file NEWS in this directory.
-
-PCI sound cards are highly recommended, as they are far
-easier to configure and from what I have read, they use
-less resources and are more CPU efficient.
-
-
-INSMOD:
-=======
-
-If loading via insmod, the common modules must be loaded in the
-order below BEFORE loading the other sound modules. The card-specific
-modules may then be loaded (most require parameters). For example,
-I use the following via a shell script to load my SoundBlaster:
-
-SB_BASE=0x240
-SB_IRQ=9
-SB_DMA=3
-SB_DMA2=5
-SB_MPU=0x300
-#
-echo Starting sound
-/sbin/insmod soundcore
-/sbin/insmod sound
-#
-echo Starting sound blaster....
-/sbin/insmod uart401
-/sbin/insmod sb io=$SB_BASE irq=$SB_IRQ dma=$SB_DMA dma16=$SB_DMA2 mpu_io=$SB_MP
-
-When using sound as a module, I typically put these commands
-in a file such as /root/soundon.sh.
-
-
-MODPROBE:
-=========
-
-If loading via modprobe, these common files are automatically loaded when
-requested by modprobe. For example, my /etc/modprobe.d/oss.conf contains:
-
-alias sound sb
-options sb io=0x240 irq=9 dma=3 dma16=5 mpu_io=0x300
-
-All you need to do to load the module is:
-
- /sbin/modprobe sb
-
-
-Sound Status:
-=============
-
-The status of sound may be read/checked by:
- cat (anyfile).au >/dev/audio
-
-[WWH: This may not work properly for SoundBlaster PCI 128 cards
-such as the es1370/1 (see the es1370/1 files in this directory)
-as they do not automatically support uLaw on /dev/audio.]
-
-The status of the modules and which modules depend on
-which other modules may be checked by:
- /sbin/lsmod
-
-/sbin/lsmod should show something like the following:
- sb 26280 0
- uart401 5640 0 [sb]
- sound 57112 0 [sb uart401]
- soundcore 1968 8 [sb sound]
-
-
-Removing Sound:
-===============
-
-Sound may be removed by using /sbin/rmmod in the reverse order
-in which you load the modules. Note, if a program has a sound device
-open (e.g., xmixer), that module (and the modules on which it
-depends) may not be unloaded.
-
-For example, I use the following to remove my Soundblaster (rmmod
-in the reverse order in which I loaded the modules):
-
-/sbin/rmmod sb
-/sbin/rmmod uart401
-/sbin/rmmod sound
-/sbin/rmmod soundcore
-
-When using sound as a module, I typically put these commands
-in a script such as /root/soundoff.sh.
-
-
-Removing Sound for use with OSS:
-================================
-
-If you get really stuck or have a card that the kernel modules
-will not support, you can get a commercial sound driver from
-http://www.opensound.com. Before loading the commercial sound
-driver, you should do the following:
-
-1. remove sound modules (detailed above)
-2. remove the sound modules from /etc/modprobe.d/*.conf
-3. move the sound modules from /lib/modules/<kernel>/misc
- (for example, I make a /lib/modules/<kernel>/misc/tmp
- directory and copy the sound module files to that
- directory).
-
-
-Multiple Sound Cards:
-=====================
-
-The sound drivers will support multiple sound cards and there
-are some great applications like multitrack that support them.
-Typically, you need two sound cards of different types. Note, this
-uses more precious interrupts and DMA channels and sometimes
-can be a configuration nightmare. I have heard reports of 3-4
-sound cards (typically I only use 2). You can sometimes use
-multiple PCI sound cards of the same type.
-
-On my machine I have two sound cards (cs4232 and Soundblaster Vibra
-16). By loading sound as modules, I can control which is the first
-sound device (/dev/dsp, /dev/audio, /dev/mixer) and which is
-the second. Normally, the cs4232 (Dell sound on the motherboard)
-would be the first sound device, but I prefer the Soundblaster.
-All you have to do is to load the one you want as /dev/dsp
-first (in my case "sb") and then load the other one
-(in my case "cs4232").
-
-If you have two cards of the same type that are jumpered
-cards or different PnP revisions, you may load the same
-module twice. For example, I have a SoundBlaster vibra 16
-and an older SoundBlaster 16 (jumpers). To load the module
-twice, you need to do the following:
-
-1. Copy the sound modules to a new name. For example
- sb.o could be copied (or symlinked) to sb1.o for the
- second SoundBlaster.
-
-2. Make a second entry in /etc/modprobe.d/*conf, for example,
- sound1 or sb1. This second entry should refer to the
- new module names for example sb1, and should include
- the I/O, etc. for the second sound card.
-
-3. Update your soundon.sh script, etc.
-
-Warning: I have never been able to get two PnP sound cards of the
-same type to load at the same time. I have tried this several times
-with the Soundblaster Vibra 16 cards. OSS has indicated that this
-is a PnP problem.... If anyone has any luck doing this, please
-send me an E-MAIL. PCI sound cards should not have this problem.a
-Since this was originally release, I have received a couple of
-mails from people who have accomplished this!
-
-NOTE: In Linux 2.4 the Sound Blaster driver (and only this one yet)
-supports multiple cards with one module by default.
-Read the file 'Soundblaster' in this directory for details.
-
-
-Sound Problems:
-===============
-
-First RTFM (including the troubleshooting section
-in the Sound-HOWTO).
-
-1) If you are having problems loading the modules (for
- example, if you get device conflict errors) try the
- following:
-
- A) If you have Win95 or NT on the same computer,
- write down what addresses, IRQ, and DMA channels
- those were using for the same hardware. You probably
- can use these addresses, IRQs, and DMA channels.
- You should really do this BEFORE attempting to get
- sound working!
-
- B) Check (cat) /proc/interrupts, /proc/ioports,
- and /proc/dma. Are you trying to use an address,
- IRQ or DMA port that another device is using?
-
- C) Check (cat) /proc/isapnp
-
- D) Inspect your /var/log/messages file. Often that will
- indicate what IRQ or IO port could not be obtained.
-
- E) Try another port or IRQ. Note this may involve
- using the PnP tools to move the sound card to
- another location. Sometimes this is the only way
- and it is more or less trial and error.
-
-2) If you get motor-boating (the same sound or part of a
- sound clip repeated), you probably have either an IRQ
- or DMA conflict. Move the card to another IRQ or DMA
- port. This has happened to me when playing long files
- when I had an IRQ conflict.
-
-3. If you get dropouts or pauses when playing high sample
- rate files such as using mpg123 or x11amp/xmms, you may
- have too slow of a CPU and may have to use the options to
- play the files at 1/2 speed. For example, you may use
- the -2 or -4 option on mpg123. You may also get this
- when trying to play mpeg files stored on a CD-ROM
- (my Toshiba T8000 PII/366 sometimes has this problem).
-
-4. If you get "cannot access device" errors, your /dev/dsp
- files, etc. may be set to owner root, mode 600. You
- may have to use the command:
- chmod 666 /dev/dsp /dev/mixer /dev/audio
-
-5. If you get "device busy" errors, another program has the
- sound device open. For example, if using the Enlightenment
- sound daemon "esd", the "esd" program has the sound device.
- If using "esd", please RTFM the docs on ESD. For example,
- esddsp <program> may be used to play files via a non-esd
- aware program.
-
-6) Ask for help on the sound list or send E-MAIL to the
- sound driver author/maintainer.
-
-7) Turn on debug in drivers/sound/sound_config.h (DEB, DDB, MDB).
-
-8) If the system reports insufficient DMA memory then you may want to
- load sound with the "dmabufs=1" option. Or in /etc/conf.modules add
-
- preinstall sound dmabufs=1
-
- This makes the sound system allocate its buffers and hang onto them.
-
- You may also set persistent DMA when building a 2.4.x kernel.
-
-
-Configuring Sound:
-==================
-
-There are several ways of configuring your sound:
-
-1) On the kernel command line (when using the sound driver(s)
- compiled in the kernel). Check the driver source and
- documentation for details.
-
-2) On the command line when using insmod or in a bash script
- using command line calls to load sound.
-
-3) In /etc/modprobe.d/*conf when using modprobe.
-
-4) Via Red Hat's GPL'd /usr/sbin/sndconfig program (text based).
-
-5) Via the OSS soundconf program (with the commercial version
- of the OSS driver.
-
-6) By just loading the module and let isapnp do everything relevant
- for you. This works only with a few drivers yet and - of course -
- only with isapnp hardware.
-
-And I am sure, several other ways.
-
-Anyone want to write a linuxconf module for configuring sound?
-
-
-Module Loading:
-===============
-
-When a sound card is first referenced and sound is modular, the sound system
-will ask for the sound devices to be loaded. Initially it requests that
-the driver for the sound system is loaded. It then will ask for
-sound-slot-0, where 0 is the first sound card. (sound-slot-1 the second and
-so on). Thus you can do
-
-alias sound-slot-0 sb
-
-To load a soundblaster at this point. If the slot loading does not provide
-the desired device - for example a soundblaster does not directly provide
-a midi synth in all cases then it will request "sound-service-0-n" where n
-is
-
- 0 Mixer
-
- 2 MIDI
-
- 3, 4 DSP audio
-
-
-For example, I use the following to load my Soundblaster PCI 128
-(ES 1371) card first, followed by my SoundBlaster Vibra 16 card,
-then by my TV card:
-
-# Load the Soundblaster PCI 128 as /dev/dsp, /dev/dsp1, /dev/mixer
-alias sound-slot-0 es1371
-
-# Load the Soundblaster Vibra 16 as /dev/dsp2, /dev/mixer1
-alias sound-slot-1 sb
-options sb io=0x240 irq=5 dma=1 dma16=5 mpu_io=0x330
-
-# Load the BTTV (TV card) as /dev/mixer2
-alias sound-slot-2 bttv
-alias sound-service-2-0 tvmixer
-
-pre-install bttv modprobe tuner ; modprobe tvmixer
-pre-install tvmixer modprobe msp3400; modprobe tvaudio
-options tuner debug=0 type=8
-options bttv card=0 radio=0 pll=0

-# Turtle Beach MultiSound Driver Notes
-# -- Andrew Veliath <andrewtv@usa.net>
-#
-# Last update: September 10, 1998
-# Corresponding msnd driver: 0.8.3
-#
-# ** This file is a README (top part) and shell archive (bottom part).
-# The corresponding archived utility sources can be unpacked by
-# running `sh MultiSound' (the utilities are only needed for the
-# Pinnacle and Fiji cards). **
-#
-#
-# -=-=- Getting Firmware -=-=-
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# See the section `Obtaining and Creating Firmware Files' in this
-# document for instructions on obtaining the necessary firmware
-# files.
-#
-#
-# Supported Features
-# ~~~~~~~~~~~~~~~~~~
-#
-# Currently, full-duplex digital audio (/dev/dsp only, /dev/audio is
-# not currently available) and mixer functionality (/dev/mixer) are
-# supported (memory mapped digital audio is not yet supported).
-# Digital transfers and monitoring can be done as well if you have
-# the digital daughterboard (see the section on using the S/PDIF port
-# for more information).
-#
-# Support for the Turtle Beach MultiSound Hurricane architecture is
-# composed of the following modules (these can also operate compiled
-# into the kernel):
-#
-# msnd - MultiSound base (requires soundcore)
-#
-# msnd_classic - Base audio/mixer support for Classic, Monetery and
-# Tahiti cards
-#
-# msnd_pinnacle - Base audio/mixer support for Pinnacle and Fiji cards
-#
-#
-# Important Notes - Read Before Using
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# The firmware files are not included (may change in future). You
-# must obtain these images from Turtle Beach (they are included in
-# the MultiSound Development Kits), and place them in /etc/sound for
-# example, and give the full paths in the Linux configuration. If
-# you are compiling in support for the MultiSound driver rather than
-# using it as a module, these firmware files must be accessible
-# during kernel compilation.
-#
-# Please note these files must be binary files, not assembler. See
-# the section later in this document for instructions to obtain these
-# files.
-#
-#
-# Configuring Card Resources
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# ** This section is very important, as your card may not work at all
-# or your machine may crash if you do not do this correctly. **
-#
-# * Classic/Monterey/Tahiti
-#
-# These cards are configured through the driver msnd_classic. You must
-# know the io port, then the driver will select the irq and memory resources
-# on the card. It is up to you to know if these are free locations or now,
-# a conflict can lock the machine up.
-#
-# * Pinnacle/Fiji
-#
-# The Pinnacle and Fiji cards have an extra config port, either
-# 0x250, 0x260 or 0x270. This port can be disabled to have the card
-# configured strictly through PnP, however you lose the ability to
-# access the IDE controller and joystick devices on this card when
-# using PnP. The included pinnaclecfg program in this shell archive
-# can be used to configure the card in non-PnP mode, and in PnP mode
-# you can use isapnptools. These are described briefly here.
-#
-# pinnaclecfg is not required; you can use the msnd_pinnacle module
-# to fully configure the card as well. However, pinnaclecfg can be
-# used to change the resource values of a particular device after the
-# msnd_pinnacle module has been loaded. If you are compiling the
-# driver into the kernel, you must set these values during compile
-# time, however other peripheral resource values can be changed with
-# the pinnaclecfg program after the kernel is loaded.
-#
-#
-# *** PnP mode
-#
-# Use pnpdump to obtain a sample configuration if you can; I was able
-# to obtain one with the command `pnpdump 1 0x203' -- this may vary
-# for you (running pnpdump by itself did not work for me). Then,
-# edit this file and use isapnp to uncomment and set the card values.
-# Use these values when inserting the msnd_pinnacle module. Using
-# this method, you can set the resources for the DSP and the Kurzweil
-# synth (Pinnacle). Since Linux does not directly support PnP
-# devices, you may have difficulty when using the card in PnP mode
-# when it the driver is compiled into the kernel. Using non-PnP mode
-# is preferable in this case.
-#
-# Here is an example mypinnacle.conf for isapnp that sets the card to
-# io base 0x210, irq 5 and mem 0xd8000, and also sets the Kurzweil

-#
-#
-# *** Non-PnP mode
-#
-# The second way is by running the card in non-PnP mode. This
-# actually has some advantages in that you can access some other
-# devices on the card, such as the joystick and IDE controller. To
-# configure the card, unpack this shell archive and build the
-# pinnaclecfg program. Using this program, you can assign the
-# resource values to the card's devices, or disable the devices. As
-# an alternative to using pinnaclecfg, you can specify many of the
-# configuration values when loading the msnd_pinnacle module (or
-# during kernel configuration when compiling the driver into the
-# kernel).
-#
-# If you specify cfg=0x250 for the msnd_pinnacle module, it
-# automatically configure the card to the given io, irq and memory
-# values using that config port (the config port is jumper selectable
-# on the card to 0x250, 0x260 or 0x270).
-#
-# See the `msnd_pinnacle Additional Options' section below for more
-# information on these parameters (also, if you compile the driver
-# directly into the kernel, these extra parameters can be useful
-# here).
-#
-#
-# ** It is very easy to cause problems in your machine if you choose a
-# resource value which is incorrect. **
-#
-#
-# Examples
-# ~~~~~~~~
-#
-# * MultiSound Classic/Monterey/Tahiti:
-#
-# modprobe soundcore
-# insmod msnd
-# insmod msnd_classic io=0x290 irq=7 mem=0xd0000
-#
-# * MultiSound Pinnacle in PnP mode:
-#
-# modprobe soundcore
-# insmod msnd
-# isapnp mypinnacle.conf
-# insmod msnd_pinnacle io=0x210 irq=5 mem=0xd8000 <-- match mypinnacle.conf values
-#
-# * MultiSound Pinnacle in non-PnP mode (replace 0x250 with your configuration port,
-# one of 0x250, 0x260 or 0x270):
-#
-# insmod soundcore
-# insmod msnd
-# insmod msnd_pinnacle cfg=0x250 io=0x290 irq=5 mem=0xd0000
-#
-# * To use the MPU-compatible Kurzweil synth on the Pinnacle in PnP
-# mode, add the following (assumes you did `isapnp mypinnacle.conf'):
-#
-# insmod sound
-# insmod mpu401 io=0x330 irq=9 <-- match mypinnacle.conf values
-#
-# * To use the MPU-compatible Kurzweil synth on the Pinnacle in non-PnP
-# mode, add the following. Note how we first configure the peripheral's
-# resources, _then_ install a Linux driver for it:
-#
-# insmod sound
-# pinnaclecfg 0x250 mpu 0x330 9
-# insmod mpu401 io=0x330 irq=9
-#
-# -- OR you can use the following sequence without pinnaclecfg in non-PnP mode:
-#
-# insmod soundcore
-# insmod msnd
-# insmod msnd_pinnacle cfg=0x250 io=0x290 irq=5 mem=0xd0000 mpu_io=0x330 mpu_irq=9
-# insmod sound
-# insmod mpu401 io=0x330 irq=9
-#
-# * To setup the joystick port on the Pinnacle in non-PnP mode (though
-# you have to find the actual Linux joystick driver elsewhere), you
-# can use pinnaclecfg:
-#
-# pinnaclecfg 0x250 joystick 0x200
-#
-# -- OR you can configure this using msnd_pinnacle with the following:
-#
-# insmod soundcore
-# insmod msnd
-# insmod msnd_pinnacle cfg=0x250 io=0x290 irq=5 mem=0xd0000 joystick_io=0x200
-#
-#
-# msnd_classic, msnd_pinnacle Required Options
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# If the following options are not given, the module will not load.
-# Examine the kernel message log for informative error messages.
-# WARNING--probing isn't supported so try to make sure you have the
-# correct shared memory area, otherwise you may experience problems.
-#
-# io I/O base of DSP, e.g. io=0x210
-# irq IRQ number, e.g. irq=5
-# mem Shared memory area, e.g. mem=0xd8000
-#
-#
-# msnd_classic, msnd_pinnacle Additional Options
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# fifosize The digital audio FIFOs, in kilobytes. If not
-# specified, the default will be used. Increasing
-# this value will reduce the chance of a FIFO
-# underflow at the expense of increasing overall
-# latency. For example, fifosize=512 will
-# allocate 512kB read and write FIFOs (1MB total).
-# While this may reduce dropouts, a heavy machine
-# load will undoubtedly starve the FIFO of data
-# and you will eventually get dropouts. One
-# option is to alter the scheduling priority of
-# the playback process, using `nice' or some form
-# of POSIX soft real-time scheduling.
-#
-# calibrate_signal Setting this to one calibrates the ADCs to the
-# signal, zero calibrates to the card (defaults
-# to zero).
-#
-#
-# msnd_pinnacle Additional Options
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# digital Specify digital=1 to enable the S/PDIF input
-# if you have the digital daughterboard
-# adapter. This will enable access to the
-# DIGITAL1 input for the soundcard in the mixer.
-# Some mixer programs might have trouble setting
-# the DIGITAL1 source as an input. If you have
-# trouble, you can try the setdigital.c program
-# at the bottom of this document.
-#
-# cfg Non-PnP configuration port for the Pinnacle
-# and Fiji (typically 0x250, 0x260 or 0x270,
-# depending on the jumper configuration). If
-# this option is omitted, then it is assumed
-# that the card is in PnP mode, and that the
-# specified DSP resource values are already
-# configured with PnP (i.e. it won't attempt to
-# do any sort of configuration).
-#
-# When the Pinnacle is in non-PnP mode, you can use the following
-# options to configure particular devices. If a full specification
-# for a device is not given, then the device is not configured. Note
-# that you still must use a Linux driver for any of these devices
-# once their resources are setup (such as the Linux joystick driver,
-# or the MPU401 driver from OSS for the Kurzweil synth).
-#
-# mpu_io I/O port of MPU (on-board Kurzweil synth)
-# mpu_irq IRQ of MPU (on-board Kurzweil synth)
-# ide_io0 First I/O port of IDE controller
-# ide_io1 Second I/O port of IDE controller
-# ide_irq IRQ IDE controller
-# joystick_io I/O port of joystick
-#
-#
-# Obtaining and Creating Firmware Files
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# For the Classic/Tahiti/Monterey
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# Download to /tmp and unzip the following file from Turtle Beach:
-#
-# ftp://ftp.voyetra.com/pub/tbs/msndcl/msndvkit.zip
-#
-# When unzipped, unzip the file named MsndFiles.zip. Then copy the
-# following firmware files to /etc/sound (note the file renaming):
-#
-# cp DSPCODE/MSNDINIT.BIN /etc/sound/msndinit.bin
-# cp DSPCODE/MSNDPERM.REB /etc/sound/msndperm.bin
-#
-# When configuring the Linux kernel, specify /etc/sound/msndinit.bin and
-# /etc/sound/msndperm.bin for the two firmware files (Linux kernel
-# versions older than 2.2 do not ask for firmware paths, and are
-# hardcoded to /etc/sound).
-#
-# If you are compiling the driver into the kernel, these files must
-# be accessible during compilation, but will not be needed later.
-# The files must remain, however, if the driver is used as a module.
-#
-#
-# For the Pinnacle/Fiji
-# ~~~~~~~~~~~~~~~~~~~~~
-#
-# Download to /tmp and unzip the following file from Turtle Beach (be
-# sure to use the entire URL; some have had trouble navigating to the
-# URL):
-#
-# ftp://ftp.voyetra.com/pub/tbs/pinn/pnddk100.zip
-#
-# Unpack this shell archive, and run make in the created directory
-# (you need a C compiler and flex to build the utilities). This
-# should give you the executables conv, pinnaclecfg and setdigital.
-# conv is only used temporarily here to create the firmware files,
-# while pinnaclecfg is used to configure the Pinnacle or Fiji card in
-# non-PnP mode, and setdigital can be used to set the S/PDIF input on
-# the mixer (pinnaclecfg and setdigital should be copied to a
-# convenient place, possibly run during system initialization).
-#
-# To generating the firmware files with the `conv' program, we create
-# the binary firmware files by doing the following conversion
-# (assuming the archive unpacked into a directory named PINNDDK):
-#
-# ./conv < PINNDDK/dspcode/pndspini.asm > /etc/sound/pndspini.bin
-# ./conv < PINNDDK/dspcode/pndsperm.asm > /etc/sound/pndsperm.bin
-#
-# The conv (and conv.l) program is not needed after conversion and can
-# be safely deleted. Then, when configuring the Linux kernel, specify
-# /etc/sound/pndspini.bin and /etc/sound/pndsperm.bin for the two
-# firmware files (Linux kernel versions older than 2.2 do not ask for
-# firmware paths, and are hardcoded to /etc/sound).
-#
-# If you are compiling the driver into the kernel, these files must
-# be accessible during compilation, but will not be needed later.
-# The files must remain, however, if the driver is used as a module.
-#
-#
-# Using Digital I/O with the S/PDIF Port
-# ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-#
-# If you have a Pinnacle or Fiji with the digital daughterboard and
-# want to set it as the input source, you can use this program if you
-# have trouble trying to do it with a mixer program (be sure to
-# insert the module with the digital=1 option, or say Y to the option
-# during compiled-in kernel operation). Upon selection of the S/PDIF
-# port, you should be able monitor and record from it.
-#
-# There is something to note about using the S/PDIF port. Digital
-# timing is taken from the digital signal, so if a signal is not
-# connected to the port and it is selected as recording input, you
-# will find PCM playback to be distorted in playback rate. Also,
-# attempting to record at a sampling rate other than the DAT rate may
-# be problematic (i.e. trying to record at 8000Hz when the DAT signal
-# is 44100Hz). If you have a problem with this, set the recording
-# input to analog if you need to record at a rate other than that of
-# the DAT rate.
-#

-Support for the OPTi 82C931 chip
---------------------------------
-Note: parts of this README file apply also to other
-cards that use the mad16 driver.
-
-Some items in this README file are based on features
-added to the sound driver after Linux-2.1.91 was out.
-By the time of writing this I do not know which official
-kernel release will include these features.
-Please do not report inconsistencies on older Linux
-kernels.
-
-The OPTi 82C931 is supported in its non-PnP mode.
-Usually you do not need to set jumpers, etc. The sound driver
-will check the card status and if it is required it will
-force the card into a mode in which it can be programmed.
-
-If you have another OS installed on your computer it is recommended
-that Linux and the other OS use the same resources.
-
-Also, it is recommended that resources specified in /etc/modprobe.d/*.conf
-and resources specified in /etc/isapnp.conf agree.
-
-Compiling the sound driver
---------------------------
-I highly recommend that you build a modularized sound driver.
-This document does not cover a sound-driver which is built in
-the kernel.
-
-Sound card support should be enabled as a module (chose m).
-Answer 'm' for these items:
- Generic OPL2/OPL3 FM synthesizer support (CONFIG_SOUND_ADLIB)
- Microsoft Sound System support (CONFIG_SOUND_MSS)
- Support for OPTi MAD16 and/or Mozart based cards (CONFIG_SOUND_MAD16)
- FM synthesizer (YM3812/OPL-3) support (CONFIG_SOUND_YM3812)
-
-The configuration menu may ask for addresses, IRQ lines or DMA
-channels. If the card is used as a module the module loading
-options will override these values.
-
-For the OPTi 931 you can answer 'n' to:
- Support MIDI in older MAD16 based cards (requires SB) (CONFIG_SOUND_MAD16_OLDCARD)
-If you do need MIDI support in a Mozart or C928 based card you
-need to answer 'm' to the above question. In that case you will
-also need to answer 'm' to:
- '100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support' (CONFIG_SOUND_SB)
-
-Go on and compile your kernel and modules. Install the modules. Run depmod -a.
-
-Using isapnptools
------------------
-In most systems with a PnP BIOS you do not need to use isapnp. The
-initialization provided by the BIOS is sufficient for the driver
-to pick up the card and continue initialization.
-
-If that fails, or if you have other PnP cards, you need to use isapnp
-to initialize the card.
-This was tested with isapnptools-1.11 but I recommend that you use
-isapnptools-1.13 (or newer). Run pnpdump to dump the information
-about your PnP cards. Then edit the resulting file and select
-the options of your choice. This file is normally installed as
-/etc/isapnp.conf.
-
-The driver has one limitation with respect to I/O port resources:
-IO3 base must be 0x0E0C. Although isapnp allows other ports, this
-address is hard-coded into the driver.
-
-Using kmod and autoloading the sound driver
--------------------------------------------
-Config files in '/etc/modprobe.d/' are used as below:
-
-alias mixer0 mad16
-alias audio0 mad16
-alias midi0 mad16
-alias synth0 opl3
-options sb mad16=1
-options mad16 irq=10 dma=0 dma16=1 io=0x530 joystick=1 cdtype=0
-options opl3 io=0x388
-install mad16 /sbin/modprobe -i mad16 && /sbin/ad1848_mixer_reroute 14 8 15 3 16 6
-
-If you have an MPU daughtercard or onboard MPU you will want to add to the
-"options mad16" line - eg
-
-options mad16 irq=5 dma=0 dma16=3 io=0x530 mpu_io=0x330 mpu_irq=9
-
-To set the I/O and IRQ of the MPU.
-
-
-Explain:
-
-alias mixer0 mad16
-alias audio0 mad16
-alias midi0 mad16
-alias synth0 opl3
-
-When any sound device is opened the kernel requests auto-loading
-of char-major-14. There is a built-in alias that translates this
-request to loading the main sound module.
-
-The sound module in its turn will request loading of a sub-driver
-for mixer, audio, midi or synthesizer device. The first 3 are
-supported by the mad16 driver. The synth device is supported
-by the opl3 driver.
-
-There is currently no way to autoload the sound device driver
-if more than one card is installed.
-
-options sb mad16=1
-
-This is left for historical reasons. If you enable the
-config option 'Support MIDI in older MAD16 based cards (requires SB)'
-or if you use an older mad16 driver it will force loading of the
-SoundBlaster driver. This option tells the SB driver not to look
-for a SB card but to wait for the mad16 driver.
-
-options mad16 irq=10 dma=0 dma16=1 io=0x530 joystick=1 cdtype=0
-options opl3 io=0x388
-
-post-install mad16 /sbin/ad1848_mixer_reroute 14 8 15 3 16 6
-
-This sets resources and options for the mad16 and opl3 drivers.
-I use two DMA channels (only one is required) to enable full duplex.
-joystick=1 enables the joystick port. cdtype=0 disables the cd port.
-You can also set mpu_io and mpu_irq in the mad16 options for the
-uart401 driver.
-
-This tells modprobe to run /sbin/ad1848_mixer_reroute after
-mad16 is successfully loaded and initialized. The source
-for ad1848_mixer_reroute is appended to the end of this readme
-file. It is impossible for the sound driver to know the actual
-connections to the mixer. The 3 inputs intended for cd, synth
-and line-in are mapped to the generic inputs line1, line2 and
-line3. This program reroutes these mixer channels to their
-right names (note the right mapping depends on the actual sound
-card that you use).
-The numeric parameters mean:
- 14=line1 8=cd - reroute line1 to the CD input.
- 15=line2 3=synth - reroute line2 to the synthesizer input.
- 16=line3 6=line - reroute line3 to the line input.
-For reference on other input names look at the file
-/usr/include/linux/soundcard.h.
-
-Using a joystick
------------------
-You must enable a joystick in the mad16 options. (also
-in /etc/isapnp.conf if you use it).
-Tested with regular analog joysticks.
-
-A CDROM drive connected to the sound card
------------------------------------------
-The 82C931 chip has support only for secondary ATAPI cdrom.
-(cdtype=8). Loading the mad16 driver resets the C931 chip
-and if a cdrom was already mounted it may cause a complete
-system hang. Do not use the sound card if you have an alternative.
-If you do use the sound card it is important that you load
-the mad16 driver (use "modprobe mad16" to prevent auto-unloading)
-before the cdrom is accessed the first time.
-
-Using the sound driver built-in to the kernel may help here, but...
-Most new systems have a PnP BIOS and also two IDE controllers.
-The IDE controller on the sound card may be needed only on older
-systems (which have only one IDE controller) but these systems
-also do not have a PnP BIOS - requiring isapnptools and a modularized
-driver.
-
-Known problems
---------------
-1. See the section on "A CDROM drive connected to the sound card".
-
-2. On my system the codec cannot capture companded sound samples.
- (eg., recording from /dev/audio). When any companded capture is
- requested I get stereo-16 bit samples instead. Playback of
- companded samples works well. Apparently this problem is not common
- to all C931 based cards. I do not know how to identify cards that
- have this problem.

-Pro Audio Spectrum 16 for 2.3.99 and later
-=========================================
-by Thomas Molina (tmolina@home.com)
-last modified 3 Mar 2001
-Acknowledgement to Axel Boldt (boldt@math.ucsb.edu) for stuff taken
-from Configure.help, Riccardo Facchetti for stuff from README.OSS,
-and others whose names I could not find.
-
-This documentation is relevant for the PAS16 driver (pas2_card.c and
-friends) under kernel version 2.3.99 and later. If you are
-unfamiliar with configuring sound under Linux, please read the
-Sound-HOWTO, Documentation/sound/oss/Introduction and other
-relevant docs first.
-
-The following information is relevant information from README.OSS
-and legacy docs for the Pro Audio Spectrum 16 (PAS16):
-==================================================================
-
-The pas2_card.c driver supports the following cards --
-Pro Audio Spectrum 16 (PAS16) and compatibles:
- Pro Audio Spectrum 16
- Pro Audio Studio 16
- Logitech Sound Man 16
- NOTE! The original Pro Audio Spectrum as well as the PAS+ are not
- and will not be supported by the driver.
-
-The sound driver configuration dialog
--------------------------------------
-
-Sound configuration starts by making some yes/no questions. Be careful
-when answering to these questions since answering y to a question may
-prevent some later ones from being asked. For example don't answer y to
-the question about (PAS16) if you don't really have a PAS16. Sound
-configuration may also be made modular by answering m to configuration
-options presented.
-
-Note also that all questions may not be asked. The configuration program
-may disable some questions depending on the earlier choices. It may also
-select some options automatically as well.
-
- "ProAudioSpectrum 16 support",
- - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_,
- Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that
- you read the above list correctly). Don't answer 'y' if you
- have some other card made by Media Vision or Logitech since they
- are not PAS16 compatible.
- NOTE! Since 3.5-beta10 you need to enable SB support (next question)
- if you want to use the SB emulation of PAS16. It's also possible to
- the emulation if you want to use a true SB card together with PAS16
- (there is another question about this that is asked later).
-
- "Generic OPL2/OPL3 FM synthesizer support",
- - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
- The PAS16 has an OPL3-compatible FM chip.
-
-With PAS16 you can use two audio device files at the same time. /dev/dsp (and
-/dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and
-/dev/audio1) is connected to the SB emulation (8 bit mono only).
-
-
-The new stuff for 2.3.99 and later
-============================================================================
-The following configuration options are relevant to configuring the PAS16:
-
-Sound card support
-CONFIG_SOUND
- If you have a sound card in your computer, i.e. if it can say more
- than an occasional beep, say Y. Be sure to have all the information
- about your sound card and its configuration down (I/O port,
- interrupt and DMA channel), because you will be asked for it.
-
- You want to read the Sound-HOWTO, available from
- http://www.tldp.org/docs.html#howto . General information
- about the modular sound system is contained in the files
- Documentation/sound/oss/Introduction. The file
- Documentation/sound/oss/README.OSS contains some slightly outdated but
- still useful information as well.
-
-OSS sound modules
-CONFIG_SOUND_OSS
- OSS is the Open Sound System suite of sound card drivers. They make
- sound programming easier since they provide a common API. Say Y or M
- here (the module will be called sound.o) if you haven't found a
- driver for your sound card above, then pick your driver from the
- list below.
-
-Persistent DMA buffers
-CONFIG_SOUND_DMAP
- Linux can often have problems allocating DMA buffers for ISA sound
- cards on machines with more than 16MB of RAM. This is because ISA
- DMA buffers must exist below the 16MB boundary and it is quite
- possible that a large enough free block in this region cannot be
- found after the machine has been running for a while. If you say Y
- here the DMA buffers (64Kb) will be allocated at boot time and kept
- until the shutdown. This option is only useful if you said Y to
- "OSS sound modules", above. If you said M to "OSS sound modules"
- then you can get the persistent DMA buffer functionality by passing
- the command-line argument "dmabuf=1" to the sound.o module.
-
- Say y here for PAS16.
-
-ProAudioSpectrum 16 support
-CONFIG_SOUND_PAS
- Answer Y only if you have a Pro Audio Spectrum 16, ProAudio Studio
- 16 or Logitech SoundMan 16 sound card. Don't answer Y if you have
- some other card made by Media Vision or Logitech since they are not
- PAS16 compatible. It is not necessary to enable the separate
- Sound Blaster support; it is included in the PAS driver.
-
- If you compile the driver into the kernel, you have to add
- "pas2=<io>,<irq>,<dma>,<dma2>,<sbio>,<sbirq>,<sbdma>,<sbdma2>
- to the kernel command line.
-
-FM Synthesizer (YM3812/OPL-3) support
-CONFIG_SOUND_YM3812
- Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
- Answering Y is usually a safe and recommended choice, however some
- cards may have software (TSR) FM emulation. Enabling FM support with
- these cards may cause trouble (I don't currently know of any such
- cards, however).
- Please read the file Documentation/sound/oss/OPL3 if your card has an
- OPL3 chip.
- If you compile the driver into the kernel, you have to add
- "opl3=<io>" to the kernel command line.
-
- If you compile your drivers into the kernel, you MUST configure
- OPL3 support as a module for PAS16 support to work properly.
- You can then get OPL3 functionality by issuing the command:
- insmod opl3
- In addition, you must either add the following line to
- /etc/modprobe.d/*.conf:
- options opl3 io=0x388
- or else add the following line to /etc/lilo.conf:
- opl3=0x388
-
-
-EXAMPLES
-===================================================================
-To use the PAS16 in my computer I have enabled the following sound
-configuration options:
-
-CONFIG_SOUND=y
-CONFIG_SOUND_OSS=y
-CONFIG_SOUND_TRACEINIT=y
-CONFIG_SOUND_DMAP=y
-CONFIG_SOUND_PAS=y
-CONFIG_SOUND_SB=n
-CONFIG_SOUND_YM3812=m
-
-I have also included the following append line in /etc/lilo.conf:
-append="pas2=0x388,10,3,-1,0x220,5,1,-1 sb=0x220,5,1,-1 opl3=0x388"
-
-The io address of 0x388 is default configuration on the PAS16. The
-irq of 10 and dma of 3 may not match your installation. The above
-configuration enables PAS16, 8-bit Soundblaster and OPL3
-functionality. If Soundblaster functionality is not desired, the
-following line would be appropriate:
-append="pas2=0x388,10,3,-1,0,-1,-1,-1 opl3=0x388"
-
-If sound is built totally modular, the above options may be
-specified in /etc/modprobe.d/*.conf for pas2, sb and opl3
-respectively.

-The PSS cards and other ECHO based cards provide an onboard DSP with
-downloadable programs and also has an AD1848 "Microsoft Sound System"
-device. The PSS driver enables MSS and MPU401 modes of the card. SB
-is not enabled since it doesn't work concurrently with MSS.
-
-If you build this driver as a module then the driver takes the following
-parameters
-
-pss_io. The I/O base the PSS card is configured at (normally 0x220
- or 0x240)
-
-mss_io The base address of the Microsoft Sound System interface.
- This is normally 0x530, but may be 0x604 or other addresses.
-
-mss_irq The interrupt assigned to the Microsoft Sound System
- emulation. IRQ's 3,5,7,9,10,11 and 12 are available. If you
- get IRQ errors be sure to check the interrupt is set to
- "ISA/Legacy" in the BIOS on modern machines.
-
-mss_dma The DMA channel used by the Microsoft Sound System.
- This can be 0, 1, or 3. DMA 0 is not available on older
- machines and will cause a crash on them.
-
-mpu_io The MPU emulation base address. This sets the base of the
- synthesizer. It is typically 0x330 but can be altered.
-
-mpu_irq The interrupt to use for the synthesizer. It must differ
- from the IRQ used by the Microsoft Sound System port.
-
-
-The mpu_io/mpu_irq fields are optional. If they are not specified the
-synthesizer parts are not configured.
-
-When the module is loaded it looks for a file called
-/etc/sound/pss_synth. This is the firmware file from the DOS install disks.
-This fil holds a general MIDI emulation. The file expected is called
-genmidi.ld on newer DOS driver install disks and synth.ld on older ones.
-
-You can also load alternative DSP algorithms into the card if you wish. One
-alternative driver can be found at http://www.mpg123.de/

- This file contains notes for users of PSS sound cards who wish to use the
-newly added features of the newest version of this driver.
-
- The major enhancements present in this new revision of this driver is the
-addition of two new module parameters that allow you to take full advantage of
-all the features present on your PSS sound card. These features include the
-ability to enable both the builtin CDROM and joystick ports.
-
-pss_enable_joystick
-
- This parameter is basically a flag. A 0 will leave the joystick port
-disabled, while a non-zero value would enable the joystick port. The default
-setting is pss_enable_joystick=0 as this keeps this driver fully compatible
-with systems that were using previous versions of this driver. If you wish to
-enable the joystick port you will have to add pss_enable_joystick=1 as an
-argument to the driver. To actually use the joystick port you will then have
-to load the joystick driver itself. Just remember to load the joystick driver
-AFTER the pss sound driver.
-
-pss_cdrom_port
-
- This parameter takes a port address as its parameter. Any available port
-address can be specified to enable the CDROM port, except for 0x0 and -1 as
-these values would leave the port disabled. Like the joystick port, the cdrom
-port will require that an appropriate CDROM driver be loaded before you can make
-use of the newly enabled CDROM port. Like the joystick port option above,
-remember to load the CDROM driver AFTER the pss sound driver. While it may
-differ on some PSS sound cards, all the PSS sound cards that I have seen have a
-builtin Wearnes CDROM port. If this is the case with your PSS sound card you
-should load aztcd with the appropriate port option that matches the port you
-assigned to the CDROM port when you loaded your pss sound driver. (ex.
-modprobe pss pss_cdrom_port=0x340 && modprobe aztcd aztcd=0x340) The default
-setting of this parameter leaves the CDROM port disabled to maintain full
-compatibility with systems using previous versions of this driver.
-
- Other options have also been added for the added convenience and utility
-of the user. These options are only available if this driver is loaded as a
-module.
-
-pss_no_sound
-
- This module parameter is a flag that can be used to tell the driver to
-just configure non-sound components. 0 configures all components, a non-0
-value will only attempt to configure the CDROM and joystick ports. This
-parameter can be used by a user who only wished to use the builtin joystick
-and/or CDROM port(s) of his PSS sound card. If this driver is loaded with this
-parameter and with the parameter below set to true then a user can safely unload
-this driver with the following command "rmmod pss && rmmod ad1848 && rmmod
-mpu401 && rmmod sound && rmmod soundcore" and retain the full functionality of
-his CDROM and/or joystick port(s) while gaining back the memory previously used
-by the sound drivers. This default setting of this parameter is 0 to retain
-full behavioral compatibility with previous versions of this driver.
-
-pss_keep_settings
-
- This parameter can be used to specify whether you want the driver to reset
-all emulations whenever its unloaded. This can be useful for those who are
-sharing resources (io ports, IRQ's, DMA's) between different ISA cards. This
-flag can also be useful in that future versions of this driver may reset all
-emulations by default on the driver's unloading (as it probably should), so
-specifying it now will ensure that all future versions of this driver will
-continue to work as expected. The default value of this parameter is 1 to
-retain full behavioral compatibility with previous versions of this driver.
-
-pss_firmware
-
- This parameter can be used to specify the file containing the firmware
-code so that a user could tell the driver where that file is located instead
-of having to put it in a predefined location with a predefined name. The
-default setting of this parameter is "/etc/sound/pss_synth" as this was the
-path and filename the hardcoded value in the previous versions of this driver.
-
-Examples:
-
-# Normal PSS sound card system, loading of drivers.
-# Should be specified in an rc file (ex. Slackware uses /etc/rc.d/rc.modules).
-
-/sbin/modprobe pss pss_io=0x220 mpu_io=0x338 mpu_irq=9 mss_io=0x530 mss_irq=10 mss_dma=1 pss_cdrom_port=0x340 pss_enable_joystick=1
-/sbin/modprobe aztcd aztcd=0x340
-/sbin/modprobe joystick
-
-# System using the PSS sound card just for its CDROM and joystick ports.
-# Should be specified in an rc file (ex. Slackware uses /etc/rc.d/rc.modules).
-
-/sbin/modprobe pss pss_io=0x220 pss_cdrom_port=0x340 pss_enable_joystick=1 pss_no_sound=1
-/sbin/rmmod pss && /sbin/rmmod ad1848 && /sbin/rmmod mpu401 && /sbin/rmmod sound && /sbin/rmmod soundcore # This line not needed, but saves memory.
-/sbin/modprobe aztcd aztcd=0x340

-Introduction
-------------
-
-This file is a collection of all the old Readme files distributed with
-OSS/Lite by Hannu Savolainen. Since the new Linux sound driver is founded
-on it I think these information may still be interesting for users that
-have to configure their sound system.
-
-Be warned: Alan Cox is the current maintainer of the Linux sound driver so if
-you have problems with it, please contact him or the current device-specific
-driver maintainer (e.g. for aedsp16 specific problems contact me). If you have
-patches, contributions or suggestions send them to Alan: I'm sure they are
-welcome.
-
-In this document you will find a lot of references about OSS/Lite or ossfree:
-they are gone forever. Keeping this in mind and with a grain of salt this
-document can be still interesting and very helpful.

-OSS/Free version 3.8 release notes
-----------------------------------
-
-Please read the SOUND-HOWTO (available from sunsite.unc.edu and other Linux FTP
-sites). It gives instructions about using sound with Linux. It's bit out of
-date but still very useful. Information about bug fixes and such things
-is available from the web page (see above).
-
-Please check http://www.opensound.com/pguide for more info about programming
-with OSS API.

-
-Sending your contributions or patches
--------------------------------------
-
-First of all it's highly recommended to contact me before sending anything
-or before even starting to do any work. Tell me what you suggest to be
-changed or what you have planned to do. Also ensure you are using the
-very latest (development) version of OSS/Free since the change may already be
-implemented there. In general it's a major waste of time to try to improve a
-several months old version. Information about the latest version can be found
-from http://www.opensound.com/ossfree. In general there is no point in
-sending me patches relative to production kernels.
-

-
-If you have some problems
-=========================
-
-Read the sound HOWTO (sunsite.unc.edu:/pub/Linux/docs/...?).
-Also look at the home page (http://www.opensound.com/ossfree). It may
-contain info about some recent bug fixes.
-
-It's likely that you have some problems when trying to use the sound driver
-first time. Sound cards don't have standard configuration so there are no
-good default configuration to use. Please try to use same I/O, DMA and IRQ
-values for the sound card than with DOS.
-
-If you get an error message when trying to use the driver, please look
-at /var/adm/messages for more verbose error message.
-
-
-The following errors are likely with /dev/dsp and /dev/audio.
-
- - "No such device or address".
- This error indicates that there are no suitable hardware for the
- device file or the sound driver has been compiled without support for
- this particular device. For example /dev/audio and /dev/dsp will not
- work if "digitized voice support" was not enabled during "make config".
-
- - "Device or resource busy". Probably the IRQ (or DMA) channel
- required by the sound card is in use by some other device/driver.
-
- - "I/O error". Almost certainly (99%) it's an IRQ or DMA conflict.
- Look at the kernel messages in /var/adm/notice for more info.
-
- - "Invalid argument". The application is calling ioctl()
- with impossible parameters. Check that the application is
- for sound driver version 2.X or later.
-
-Linux installation
-==================
-
-IMPORTANT! Read this if you are installing a separately
- distributed version of this driver.
-
- Check that your kernel version works with this
- release of the driver (see Readme). Also verify
- that your current kernel version doesn't have more
- recent sound driver version than this one. IT'S HIGHLY
- RECOMMENDED THAT YOU USE THE SOUND DRIVER VERSION THAT
- IS DISTRIBUTED WITH KERNEL SOURCES.
-
-- When installing separately distributed sound driver you should first
- read the above notice. Then try to find proper directory where and how
- to install the driver sources. You should not try to install a separately
- distributed driver version if you are not able to find the proper way
- yourself (in this case use the version that is distributed with kernel
- sources). Remove old version of linux/drivers/sound directory before
- installing new files.
-
-- To build the device files you need to run the enclosed shell script
- (see below). You need to do this only when installing sound driver
- first time or when upgrading to much recent version than the earlier
- one.
-
-- Configure and compile Linux as normally (remember to include the
- sound support during "make config"). Please refer to kernel documentation
- for instructions about configuring and compiling kernel. File Readme.cards
- contains card specific instructions for configuring this driver for
- use with various sound cards.
-
-Boot time configuration (using lilo and insmod)
------------------------------------------------
-
-This information has been removed. Too many users didn't believe
-that it's really not necessary to use this method. Please look at
-Readme of sound driver version 3.0.1 if you still want to use this method.
-
-Problems
---------
-
-Common error messages:
-
-- /dev/???????: No such file or directory.
-Run the script at the end of this file.
-
-- /dev/???????: No such device.
-You are not running kernel which contains the sound driver. When using
-modularized sound driver this error means that the sound driver is not
-loaded.
-
-- /dev/????: No such device or address.
-Sound driver didn't detect suitable card when initializing. Please look at
-Readme.cards for info about configuring the driver with your card. Also
-check for possible boot (insmod) time error messages in /var/adm/messages.
-
-- Other messages or problems
-Please check http://www.opensound.com/ossfree for more info.
-
-Configuring version 3.8 (for Linux) with some common sound cards
-================================================================
-
-This document describes configuring sound cards with the freeware version of
-Open Sound Systems (OSS/Free). Information about the commercial version
-(OSS/Linux) and its configuration is available from
-http://www.opensound.com/linux.html. Information presented here is
-not valid for OSS/Linux.
-
-If you are unsure about how to configure OSS/Free
-you can download the free evaluation version of OSS/Linux from the above
-address. There is a chance that it can autodetect your sound card. In this case
-you can use the information included in soundon.log when configuring OSS/Free.
-
-
-IMPORTANT! This document covers only cards that were "known" when
- this driver version was released. Please look at
- http://www.opensound.com/ossfree for info about
- cards introduced recently.
-
- When configuring the sound driver, you should carefully
- check each sound configuration option (particularly
- "Support for /dev/dsp and /dev/audio"). The default values
- offered by these programs are not necessarily valid.
-
-
-THE BIGGEST MISTAKES YOU CAN MAKE
-=================================
-
-1. Assuming that the card is Sound Blaster compatible when it's not.
---------------------------------------------------------------------
-
-The number one mistake is to assume that your card is compatible with
-Sound Blaster. Only the cards made by Creative Technology or which have
-one or more chips labeled by Creative are SB compatible. In addition there
-are few sound chipsets which are SB compatible in Linux such as ESS1688 or
-Jazz16. Note that SB compatibility in DOS/Windows does _NOT_ mean anything
-in Linux.
-
-IF YOU REALLY ARE 150% SURE YOU HAVE A SOUND BLASTER YOU CAN SKIP THE REST OF
-THIS CHAPTER.
-
-For most other "supposed to be SB compatible" cards you have to use other
-than SB drivers (see below). It is possible to get most sound cards to work
-in SB mode but in general it's a complete waste of time. There are several
-problems which you will encounter by using SB mode with cards that are not
-truly SB compatible:
-
-- The SB emulation is at most SB Pro (DSP version 3.x) which means that
-you get only 8 bit audio (there is always an another ("native") mode which
-gives the 16 bit capability). The 8 bit only operation is the reason why
-many users claim that sound quality in Linux is much worse than in DOS.
-In addition some applications require 16 bit mode and they produce just
-noise with a 8 bit only device.
-- The card may work only in some cases but refuse to work most of the
-time. The SB compatible mode always requires special initialization which is
-done by the DOS/Windows drivers. This kind of cards work in Linux after
-you have warm booted it after DOS but they don't work after cold boot
-(power on or reset).
-- You get the famous "DMA timed out" messages. Usually all SB clones have
-software selectable IRQ and DMA settings. If the (power on default) values
-currently used by the card don't match configuration of the driver you will
-get the above error message whenever you try to record or play. There are
-few other reasons to the DMA timeout message but using the SB mode seems
-to be the most common cause.
-
-2. Trying to use a PnP (Plug & Play) card just like an ordinary sound card
---------------------------------------------------------------------------
-
-Plug & Play is a protocol defined by Intel and Microsoft. It lets operating
-systems to easily identify and reconfigure I/O ports, IRQs and DMAs of ISA
-cards. The problem with PnP cards is that the standard Linux doesn't currently
-(versions 2.1.x and earlier) don't support PnP. This means that you will have
-to use some special tricks (see later) to get a PnP card alive. Many PnP cards
-work after they have been initialized but this is not always the case.
-
-There are sometimes both PnP and non-PnP versions of the same sound card.
-The non-PnP version is the original model which usually has been discontinued
-more than an year ago. The PnP version has the same name but with "PnP"
-appended to it (sometimes not). This causes major confusion since the non-PnP
-model works with Linux but the PnP one doesn't.
-
-You should carefully check if "Plug & Play" or "PnP" is mentioned in the name
-of the card or in the documentation or package that came with the card.
-Everything described in the rest of this document is not necessarily valid for
-PnP models of sound cards even you have managed to wake up the card properly.
-Many PnP cards are simply too different from their non-PnP ancestors which are
-covered by this document.
-
-
-Cards that are not (fully) supported by this driver
-===================================================
-
-See http://www.opensound.com/ossfree for information about sound cards
-to be supported in future.
-
-
-How to use sound without recompiling kernel and/or sound driver
-===============================================================
-
-There is a commercial sound driver which comes in precompiled form and doesn't
-require recompiling of the kernel. See http://www.4Front-tech.com/oss.html for
-more info.
-
-
-Configuring PnP cards
-=====================
-
-New versions of most sound cards use the so-called ISA PnP protocol for
-soft configuring their I/O, IRQ, DMA and shared memory resources.
-Currently at least cards made by Creative Technology (SB32 and SB32AWE
-PnP), Gravis (GUS PnP and GUS PnP Pro), Ensoniq (Soundscape PnP) and
-Aztech (some Sound Galaxy models) use PnP technology. The CS4232/4236 audio
-chip by Crystal Semiconductor (Intel Atlantis, HP Pavilion and many other
-motherboards) is also based on PnP technology but there is a "native" driver
-available for it (see information about CS4232 later in this document).
-
-PnP sound cards (as well as most other PnP ISA cards) are not supported
-by this version of the driver . Proper
-support for them should be released during 97 once the kernel level
-PnP support is available.
-
-There is a method to get most of the PnP cards to work. The basic method
-is the following:
-
-1) Boot DOS so the card's DOS drivers have a chance to initialize it.
-2) _Cold_ boot to Linux by using "loadlin.exe". Hitting ctrl-alt-del
-works with older machines but causes a hard reset of all cards on recent
-(Pentium) machines.
-3) If you have the sound driver in Linux configured properly, the card should
-work now. "Proper" means that I/O, IRQ and DMA settings are the same as in
-DOS. The hard part is to find which settings were used. See the documentation of
-your card for more info.
-
-Windows 95 could work as well as DOS but running loadlin may be difficult.
-Probably you should "shut down" your machine to MS-DOS mode before running it.
-
-Some machines have a BIOS utility for setting PnP resources. This is a good
-way to configure some cards. In this case you don't need to boot DOS/Win95
-before starting Linux.
-
-Another way to initialize PnP cards without DOS/Win95 is a Linux based
-PnP isolation tool. When writing this there is a pre alpha test version
-of such a tool available from ftp://ftp.demon.co.uk/pub/unix/linux/utils. The
-file is called isapnptools-*. Please note that this tool is just a temporary
-solution which may be incompatible with future kernel versions having proper
-support for PnP cards. There are bugs in setting DMA channels in earlier
-versions of isapnptools so at least version 1.6 is required with sound cards.
-
-Yet another way to use PnP cards is to use (commercial) OSS/Linux drivers. See
-http://www.opensound.com/linux.html for more info. This is probably the way you
-should do it if you don't want to spend time recompiling the kernel and
-required tools.
-
-
-Read this before trying to configure the driver
-===============================================
-
-There are currently many cards that work with this driver. Some of the cards
-have native support while others work since they emulate some other
-card (usually SB, MSS/WSS and/or MPU401). The following cards have native
-support in the driver. Detailed instructions for configuring these cards
-will be given later in this document.
-
-Pro Audio Spectrum 16 (PAS16) and compatibles:
- Pro Audio Spectrum 16
- Pro Audio Studio 16
- Logitech Sound Man 16
- NOTE! The original Pro Audio Spectrum as well as the PAS+ are not
- and will not be supported by the driver.
-
-Media Vision Jazz16 based cards
- Pro Sonic 16
- Logitech SoundMan Wave
- (Other Jazz based cards should work but I don't have any reports
- about them).
-
-Sound Blasters
- SB 1.0 to 2.0
- SB Pro
- SB 16
- SB32/64/AWE
- Configure SB32/64/AWE just like SB16. See lowlevel/README.awe
- for information about using the wave table synth.
- NOTE! AWE63/Gold and 16/32/AWE "PnP" cards need to be activated
- using isapnptools before they work with OSS/Free.
- SB16 compatible cards by other manufacturers than Creative.
- You have been fooled since there are _no_ SB16 compatible
- cards on the market (as of May 1997). It's likely that your card
- is compatible just with SB Pro but there is also a non-SB-
- compatible 16 bit mode. Usually it's MSS/WSS but it could also
- be a proprietary one like MV Jazz16 or ESS ES688. OPTi
- MAD16 chips are very common in so called "SB 16 bit cards"
- (try with the MAD16 driver).
-
- ======================================================================
- "Supposed to be SB compatible" cards.
- Forget the SB compatibility and check for other alternatives
- first. The only cards that work with the SB driver in
- Linux have been made by Creative Technology (there is at least
- one chip on the card with "CREATIVE" printed on it). The
- only other SB compatible chips are ESS and Jazz16 chips
- (maybe ALSxxx chips too but they probably don't work).
- Most other "16 bit SB compatible" cards such as "OPTi/MAD16" or
- "Crystal" are _NOT_ SB compatible in Linux.
-
- Practically all sound cards have some kind of SB emulation mode
- in addition to their native (16 bit) mode. In most cases this
- (8 bit only) SB compatible mode doesn't work with Linux. If
- you get it working it may cause problems with games and
- applications which require 16 bit audio. Some 16 bit only
- applications don't check if the card actually supports 16 bits.
- They just dump 16 bit data to a 8 bit card which produces just
- noise.
-
- In most cases the 16 bit native mode is supported by Linux.
- Use the SB mode with "clones" only if you don't find anything
- better from the rest of this doc.
- ======================================================================
-
-Gravis Ultrasound (GUS)
- GUS
- GUS + the 16 bit option
- GUS MAX
- GUS ACE (No MIDI port and audio recording)
- GUS PnP (with RAM)
-
-MPU-401 and compatibles
- The driver works both with the full (intelligent mode) MPU-401
- cards (such as MPU IPC-T and MQX-32M) and with the UART only
- dumb MIDI ports. MPU-401 is currently the most common MIDI
- interface. Most sound cards are compatible with it. However,
- don't enable MPU401 mode blindly. Many cards with native support
- in the driver have their own MPU401 driver. Enabling the standard one
- will cause a conflict with these cards. So check if your card is
- in the list of supported cards before enabling MPU401.
-
-Windows Sound System (MSS/WSS)
- Even when Microsoft has discontinued their own Sound System card
- they managed to make it a standard. MSS compatible cards are based on
- a codec chip which is easily available from at least two manufacturers
- (AD1848 by Analog Devices and CS4231/CS4248 by Crystal Semiconductor).
- Currently most sound cards are based on one of the MSS compatible codec
- chips. The CS4231 is used in the high quality cards such as GUS MAX,
- MediaTrix AudioTrix Pro and TB Tropez (GUS MAX is not MSS compatible).
-
- Having a AD1848, CS4248 or CS4231 codec chip on the card is a good
- sign. Even if the card is not MSS compatible, it could be easy to write
- support for it. Note also that most MSS compatible cards
- require special boot time initialization which may not be present
- in the driver. Also, some MSS compatible cards have native support.
- Enabling the MSS support with these cards is likely to
- cause a conflict. So check if your card is listed in this file before
- enabling the MSS support.
-
-Yamaha FM synthesizers (OPL2, OPL3 (not OPL3-SA) and OPL4)
- Most sound cards have a FM synthesizer chip. The OPL2 is a 2
- operator chip used in the original AdLib card. Currently it's used
- only in the cheapest (8 bit mono) cards. The OPL3 is a 4 operator
- FM chip which provides better sound quality and/or more available
- voices than the OPL2. The OPL4 is a new chip that has an OPL3 and
- a wave table synthesizer packed onto the same chip. The driver supports
- just the OPL3 mode directly. Most cards with an OPL4 (like
- SM Wave and AudioTrix Pro) support the OPL4 mode using MPU401
- emulation. Writing a native OPL4 support is difficult
- since Yamaha doesn't give information about their sample ROM chip.
-
- Enable the generic OPL2/OPL3 FM synthesizer support if your
- card has a FM chip made by Yamaha. Don't enable it if your card
- has a software (TRS) based FM emulator.
-
- ----------------------------------------------------------------
- NOTE! OPL3-SA is different chip than the ordinary OPL3. In addition
- to the FM synth this chip has also digital audio (WSS) and
- MIDI (MPU401) capabilities. Support for OPL3-SA is described below.
- ----------------------------------------------------------------
-
-Yamaha OPL3-SA1
-
- Yamaha OPL3-SA1 (YMF701) is an audio controller chip used on some
- (Intel) motherboards and on cheap sound cards. It should not be
- confused with the original OPL3 chip (YMF278) which is entirely
- different chip. OPL3-SA1 has support for MSS, MPU401 and SB Pro
- (not used in OSS/Free) in addition to the OPL3 FM synth.
-
- There are also chips called OPL3-SA2, OPL3-SA3, ..., OPL3SA-N. They
- are PnP chips and will not work with the OPL3-SA1 driver. You should
- use the standard MSS, MPU401 and OPL3 options with these chips and to
- activate the card using isapnptools.
-
-4Front Technologies SoftOSS
-
- SoftOSS is a software based wave table emulation which works with
- any 16 bit stereo sound card. Due to its nature a fast CPU is
- required (P133 is minimum). Although SoftOSS does _not_ use MMX
- instructions it has proven out that recent processors (which appear
- to have MMX) perform significantly better with SoftOSS than earlier
- ones. For example a P166MMX beats a PPro200. SoftOSS should not be used
- on 486 or 386 machines.
-
- The amount of CPU load caused by SoftOSS can be controlled by
- selecting the CONFIG_SOFTOSS_RATE and CONFIG_SOFTOSS_VOICES
- parameters properly (they will be prompted by make config). It's
- recommended to set CONFIG_SOFTOSS_VOICES to 32. If you have a
- P166MMX or faster (PPro200 is not faster) you can set
- CONFIG_SOFTOSS_RATE to 44100 (kHz). However with slower systems it
- recommended to use sampling rates around 22050 or even 16000 kHz.
- Selecting too high values for these parameters may hang your
- system when playing MIDI files with hight degree of polyphony
- (number of concurrently playing notes). It's also possible to
- decrease CONFIG_SOFTOSS_VOICES. This makes it possible to use
- higher sampling rates. However using fewer voices decreases
- playback quality more than decreasing the sampling rate.
-
- SoftOSS keeps the samples loaded on the system's RAM so much RAM is
- required. SoftOSS should never be used on machines with less than 16 MB
- of RAM since this is potentially dangerous (you may accidentally run out
- of memory which probably crashes the machine).
-
- SoftOSS implements the wave table API originally designed for GUS. For
- this reason all applications designed for GUS should work (at least
- after minor modifications). For example gmod/xgmod and playmidi -g are
- known to work.
-
- To work SoftOSS will require GUS compatible
- patch files to be installed on the system (in /dos/ultrasnd/midi). You
- can use the public domain MIDIA patchset available from several ftp
- sites.
-
- *********************************************************************
- IMPORTANT NOTICE! The original patch set distributed with the Gravis
- Ultrasound card is not in public domain (even though it's available from
- some FTP sites). You should contact Voice Crystal (www.voicecrystal.com)
- if you like to use these patches with SoftOSS included in OSS/Free.
- *********************************************************************
-
-PSS based cards (AD1848 + ADSP-2115 + Echo ESC614 ASIC)
- Analog Devices and Echo Speech have together defined a sound card
- architecture based on the above chips. The DSP chip is used
- for emulation of SB Pro, FM and General MIDI/MT32.
-
- There are several cards based on this architecture. The most known
- ones are Orchid SW32 and Cardinal DSP16.
-
- The driver supports downloading DSP algorithms to these cards.
-
- NOTE! You will have to use the "old" config script when configuring
- PSS cards.
-
-MediaTrix AudioTrix Pro
- The ATP card is built around a CS4231 codec and an OPL4 synthesizer
- chips. The OPL4 mode is supported by a microcontroller running a
- General MIDI emulator. There is also a SB 1.5 compatible playback mode.
-
-Ensoniq SoundScape and compatibles
- Ensoniq has designed a sound card architecture based on the
- OTTO synthesizer chip used in their professional MIDI synthesizers.
- Several companies (including Ensoniq, Reveal and Spea) are selling
- cards based on this architecture.
-
- NOTE! The SoundScape PnP is not supported by OSS/Free. Ensoniq VIVO and
- VIVO90 cards are not compatible with Soundscapes so the Soundscape
- driver will not work with them. You may want to use OSS/Linux with these
- cards.
-
-OPTi MAD16 and Mozart based cards
- The Mozart (OAK OTI-601), MAD16 (OPTi 82C928), MAD16 Pro (OPTi 82C929),
- OPTi 82C924/82C925 (in _non_ PnP mode) and OPTi 82C930 interface
- chips are used in many different sound cards, including some
- cards by Reveal miro and Turtle Beach (Tropez). The purpose of these
- chips is to connect other audio components to the PC bus. The
- interface chip performs address decoding for the other chips.
- NOTE! Tropez Plus is not MAD16 but CS4232 based.
- NOTE! MAD16 PnP cards (82C924, 82C925, 82C931) are not MAD16 compatible
- in the PnP mode. You will have to use them in MSS mode after having
- initialized them using isapnptools or DOS. 82C931 probably requires
- initialization using DOS/Windows (running isapnptools is not enough).
- It's possible to use 82C931 with OSS/Free by jumpering it to non-PnP
- mode (provided that the card has a jumper for this). In non-PnP mode
- 82C931 is compatible with 82C930 and should work with the MAD16 driver
- (without need to use isapnptools or DOS to initialize it). All OPTi
- chips are supported by OSS/Linux (both in PnP and non-PnP modes).
-
-Audio Excel DSP16
- Support for this card was written by Riccardo Faccetti
- (riccardo@cdc8g5.cdc.polimi.it). The AEDSP16 driver included in
- the lowlevel/ directory. To use it you should enable the
- "Additional low level drivers" option.
-
-Crystal CS4232 and CS4236 based cards such as AcerMagic S23, TB Tropez _Plus_ and
- many PC motherboards (Compaq, HP, Intel, ...)
- CS4232 is a PnP multimedia chip which contains a CS3231A codec,
- SB and MPU401 emulations. There is support for OPL3 too.
- Unfortunately the MPU401 mode doesn't work (I don't know how to
- initialize it). CS4236 is an enhanced (compatible) version of CS4232.
- NOTE! Don't ever try to use isapnptools with CS4232 since this will just
- freeze your machine (due to chip bugs). If you have problems in getting
- CS4232 working you could try initializing it with DOS (CS4232C.EXE) and
- then booting Linux using loadlin. CS4232C.EXE loads a secret firmware
- patch which is not documented by Crystal.
-
-Turtle Beach Maui and Tropez "classic"
- This driver version supports sample, patch and program loading commands
- described in the Maui/Tropez User's manual.
- There is now full initialization support too. The audio side of
- the Tropez is based on the MAD16 chip (see above).
- NOTE! Tropez Plus is different card than Tropez "classic" and will not
- work fully in Linux. You can get audio features working by configuring
- the card as a CS4232 based card (above).
-
-
-Jumpers and software configuration
-==================================
-
-Some of the earliest sound cards were jumper configurable. You have to
-configure the driver use I/O, IRQ and DMA settings
-that match the jumpers. Just few 8 bit cards are fully jumper
-configurable (SB 1.x/2.x, SB Pro and clones).
-Some cards made by Aztech have an EEPROM which contains the
-config info. These cards behave much like hardware jumpered cards.
-
-Most cards have jumper for the base I/O address but other parameters
-are software configurable. Sometimes there are few other jumpers too.
-
-Latest cards are fully software configurable or they are PnP ISA
-compatible. There are no jumpers on the board.
-
-The driver handles software configurable cards automatically. Just configure
-the driver to use I/O, IRQ and DMA settings which are known to work.
-You could usually use the same values than with DOS and/or Windows.
-Using different settings is possible but not recommended since it may cause
-some trouble (for example when warm booting from an OS to another or
-when installing new hardware to the machine).
-
-Sound driver sets the soft configurable parameters of the card automatically
-during boot. Usually you don't need to run any extra initialization
-programs when booting Linux but there are some exceptions. See the
-card-specific instructions below for more info.
-
-The drawback of software configuration is that the driver needs to know
-how the card must be initialized. It cannot initialize unknown cards
-even if they are otherwise compatible with some other cards (like SB,
-MPU401 or Windows Sound System).
-
-
-What if your card was not listed above?
-=======================================
-
-The first thing to do is to look at the major IC chips on the card.
-Many of the latest sound cards are based on some standard chips. If you
-are lucky, all of them could be supported by the driver. The most common ones
-are the OPTi MAD16, Mozart, SoundScape (Ensoniq) and the PSS architectures
-listed above. Also look at the end of this file for list of unsupported
-cards and the ones which could be supported later.
-
-The last resort is to send _exact_ name and model information of the card
-to me together with a list of the major IC chips (manufactured, model) to
-me. I could then try to check if your card looks like something familiar.
-
-There are many more cards in the world than listed above. The first thing to
-do with these cards is to check if they emulate some other card or interface
-such as SB, MSS and/or MPU401. In this case there is a chance to get the
-card to work by booting DOS before starting Linux (boot DOS, hit ctrl-alt-del
-and boot Linux without hard resetting the machine). In this method the
-DOS based driver initializes the hardware to use known I/O, IRQ and DMA
-settings. If sound driver is configured to use the same settings, everything
-should work OK.
-
-
-Configuring sound driver (with Linux)
-=====================================
-
-The sound driver is currently distributed as part of the Linux kernel. The
-files are in /usr/src/linux/drivers/sound/.
-
-****************************************************************************
-* ALWAYS USE THE SOUND DRIVER VERSION WHICH IS DISTRIBUTED WITH *
-* THE KERNEL SOURCE PACKAGE YOU ARE USING. SOME ALPHA AND BETA TEST *
-* VERSIONS CAN BE INSTALLED FROM A SEPARATELY DISTRIBUTED PACKAGE *
-* BUT CHECK THAT THE PACKAGE IS NOT MUCH OLDER (OR NEWER) THAN THE *
-* KERNEL YOU ARE USING. IT'S POSSIBLE THAT THE KERNEL/DRIVER *
-* INTERFACE CHANGES BETWEEN KERNEL RELEASES WHICH MAY CAUSE SOME *
-* INCOMPATIBILITY PROBLEMS. *
-* *
-* IN CASE YOU INSTALL A SEPARATELY DISTRIBUTED SOUND DRIVER VERSION, *
-* BE SURE TO REMOVE OR RENAME THE OLD SOUND DRIVER DIRECTORY BEFORE *
-* INSTALLING THE NEW ONE. LEAVING OLD FILES TO THE SOUND DRIVER *
-* DIRECTORY _WILL_ CAUSE PROBLEMS WHEN THE DRIVER IS USED OR *
-* COMPILED. *
-****************************************************************************
-
-To configure the driver, run "make config" in the kernel source directory
-(/usr/src/linux). Answer "y" or "m" to the question about Sound card support
-(after the questions about mouse, CD-ROM, ftape, etc. support). Questions
-about options for sound will then be asked.
-
-After configuring the kernel and sound driver and compile the kernel
-following instructions in the kernel README.
-
-The sound driver configuration dialog
--------------------------------------
-
-Sound configuration starts by making some yes/no questions. Be careful
-when answering to these questions since answering y to a question may
-prevent some later ones from being asked. For example don't answer y to
-the first question (PAS16) if you don't really have a PAS16. Don't enable
-more cards than you really need since they just consume memory. Also
-some drivers (like MPU401) may conflict with your SCSI controller and
-prevent kernel from booting. If you card was in the list of supported
-cards (above), please look at the card specific config instructions
-(later in this file) before starting to configure. Some cards must be
-configured in way which is not obvious.
-
-So here is the beginning of the config dialog. Answer 'y' or 'n' to these
-questions. The default answer is shown so that (y/n) means 'y' by default and
-(n/y) means 'n'. To use the default value, just hit ENTER. But be careful
-since using the default _doesn't_ guarantee anything.
-
-Note also that all questions may not be asked. The configuration program
-may disable some questions depending on the earlier choices. It may also
-select some options automatically as well.
-
- "ProAudioSpectrum 16 support",
- - Answer 'y'_ONLY_ if you have a Pro Audio Spectrum _16_,
- Pro Audio Studio 16 or Logitech SoundMan 16 (be sure that
- you read the above list correctly). Don't answer 'y' if you
- have some other card made by Media Vision or Logitech since they
- are not PAS16 compatible.
- NOTE! Since 3.5-beta10 you need to enable SB support (next question)
- if you want to use the SB emulation of PAS16. It's also possible to
- the emulation if you want to use a true SB card together with PAS16
- (there is another question about this that is asked later).
- "Sound Blaster support",
- - Answer 'y' if you have an original SB card made by Creative Labs
- or a full 100% hardware compatible clone (like Thunderboard or
- SM Games). If your card was in the list of supported cards (above),
- please look at the card specific instructions later in this file
- before answering this question. For an unknown card you may answer
- 'y' if the card claims to be SB compatible.
- Enable this option also with PAS16 (changed since v3.5-beta9).
-
- Don't enable SB if you have a MAD16 or Mozart compatible card.
-
- "Generic OPL2/OPL3 FM synthesizer support",
- - Answer 'y' if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).
- Answering 'y' is usually a safe and recommended choice. However some
- cards may have software (TSR) FM emulation. Enabling FM support
- with these cards may cause trouble. However I don't currently know
- such cards.
- "Gravis Ultrasound support",
- - Answer 'y' if you have GUS or GUS MAX. Answer 'n' if you don't
- have GUS since the GUS driver consumes much memory.
- Currently I don't have experiences with the GUS ACE so I don't
- know what to answer with it.
- "MPU-401 support (NOT for SB16)",
- - Be careful with this question. The MPU401 interface is supported
- by almost any sound card today. However some natively supported cards
- have their own driver for MPU401. Enabling the MPU401 option with
- these cards will cause a conflict. Also enabling MPU401 on a system
- that doesn't really have a MPU401 could cause some trouble. If your
- card was in the list of supported cards (above), please look at
- the card specific instructions later in this file.
-
- In MOST cases this MPU401 driver should only be used with "true"
- MIDI-only MPU401 professional cards. In most other cases there
- is another way to get the MPU401 compatible interface of a
- sound card to work.
- Support for the MPU401 compatible MIDI port of SB16, ESS1688
- and MV Jazz16 cards is included in the SB driver. Use it instead
- of this separate MPU401 driver with these cards. As well
- Soundscape, PSS and Maui drivers include their own MPU401
- options.
-
- It's safe to answer 'y' if you have a true MPU401 MIDI interface
- card.
- "6850 UART Midi support",
- - It's safe to answer 'n' to this question in all cases. The 6850
- UART interface is so rarely used.
- "PSS (ECHO-ADI2111) support",
- - Answer 'y' only if you have Orchid SW32, Cardinal DSP16 or some
- other card based on the PSS chipset (AD1848 codec + ADSP-2115
- DSP chip + Echo ESC614 ASIC CHIP).
- "16 bit sampling option of GUS (_NOT_ GUS MAX)",
- - Answer 'y' if you have installed the 16 bit sampling daughtercard
- to your GUS. Answer 'n' if you have GUS MAX. Enabling this option
- disables GUS MAX support.
- "GUS MAX support",
- - Answer 'y' only if you have a GUS MAX.
- "Microsoft Sound System support",
- - Again think carefully before answering 'y' to this question. It's
- safe to answer 'y' in case you have the original Windows Sound
- System card made by Microsoft or Aztech SG 16 Pro (or NX16 Pro).
- Also you may answer 'y' in case your card was not listed earlier
- in this file. For cards having native support in the driver, consult
- the card specific instructions later in this file. Some drivers
- have their own MSS support and enabling this option will cause a
- conflict.
- Note! The MSS driver permits configuring two DMA channels. This is a
- "nonstandard" feature and works only with very few cards (if any).
- In most cases the second DMA channel should be disabled or set to
- the same channel than the first one. Trying to configure two separate
- channels with cards that don't support this feature will prevent
- audio (at least recording) from working.
- "Ensoniq Soundscape support",
- - Answer 'y' if you have a sound card based on the Ensoniq SoundScape
- chipset. Such cards are being manufactured at least by Ensoniq,
- Spea and Reveal (note that Reveal makes other cards also). The oldest
- cards made by Spea don't work properly with Linux.
- Soundscape PnP as well as Ensoniq VIVO work only with the commercial
- OSS/Linux version.
- "MediaTrix AudioTrix Pro support",
- - Answer 'y' if you have the AudioTrix Pro.
- "Support for MAD16 and/or Mozart based cards",
- - Answer y if your card has a Mozart (OAK OTI-601) or MAD16
- (OPTi 82C928, 82C929, 82C924/82C925 or 82C930) audio interface chip.
- These chips are
- currently quite common so it's possible that many no-name cards
- have one of them. In addition the MAD16 chip is used in some
- cards made by known manufacturers such as Turtle Beach (Tropez),
- Reveal (some models) and Diamond (some recent models).
- Note OPTi 82C924 and 82C925 are MAD16 compatible only in non PnP
- mode (jumper selectable on many cards).
- "Support for TB Maui"
- - This enables TB Maui specific initialization. Works with TB Maui
- and TB Tropez (may not work with Tropez Plus).
-
-
-Then the configuration program asks some y/n questions about the higher
-level services. It's recommended to answer 'y' to each of these questions.
-Answer 'n' only if you know you will not need the option.
-
- "MIDI interface support",
- - Answering 'n' disables /dev/midi## devices and access to any
- MIDI ports using /dev/sequencer and /dev/music. This option
- also affects any MPU401 and/or General MIDI compatible devices.
- "FM synthesizer (YM3812/OPL-3) support",
- - Answer 'y' here.
- "/dev/sequencer support",
- - Answering 'n' disables /dev/sequencer and /dev/music.
-
-Entering the I/O, IRQ and DMA config parameters
------------------------------------------------
-
-After the above questions the configuration program prompts for the
-card specific configuration information. Usually just a set of
-I/O address, IRQ and DMA numbers are asked. With some cards the program
-asks for some files to be used during initialization of the card. For example
-many cards have a DSP chip or microprocessor which must be initialized by
-downloading a program (microcode) file to the card.
-
-Instructions for answering these questions are given in the next section.
-
-
-Card specific information
-=========================
-
-This section gives additional instructions about configuring some cards.
-Please refer manual of your card for valid I/O, IRQ and DMA numbers. Using
-the same settings with DOS/Windows and Linux is recommended. Using
-different values could cause some problems when switching between
-different operating systems.
-
-Sound Blasters (the original ones by Creative)
----------------------------------------------
-
-NOTE! Check if you have a PnP Sound Blaster (cards sold after summer 1995
- are almost certainly PnP ones). With PnP cards you should use isapnptools
- to activate them (see above).
-
-It's possible to configure these cards to use different I/O, IRQ and
-DMA settings. Since the possible/default settings have changed between various
-models, you have to consult manual of your card for the proper ones. It's
-a good idea to use the same values than with DOS/Windows. With SB and SB Pro
-it's the only choice. SB16 has software selectable IRQ and DMA channels but
-using different values with DOS and Linux is likely to cause troubles. The
-DOS driver is not able to reset the card properly after warm boot from Linux
-if Linux has used different IRQ or DMA values.
-
-The original (steam) Sound Blaster (versions 1.x and 2.x) use always
-DMA1. There is no way to change it.
-
-The SB16 needs two DMA channels. A 8 bit one (1 or 3) is required for
-8 bit operation and a 16 bit one (5, 6 or 7) for the 16 bit mode. In theory
-it's possible to use just one (8 bit) DMA channel by answering the 8 bit
-one when the configuration program asks for the 16 bit one. This may work
-in some systems but is likely to cause terrible noise on some other systems.
-
-It's possible to use two SB16/32/64 at the same time. To do this you should
-first configure OSS/Free for one card. Then edit local.h manually and define
-SB2_BASE, SB2_IRQ, SB2_DMA and SB2_DMA2 for the second one. You can't get
-the OPL3, MIDI and EMU8000 devices of the second card to work. If you are
-going to use two PnP Sound Blasters, ensure that they are of different model
-and have different PnP IDs. There is no way to get two cards with the same
-card ID and serial number to work. The easiest way to check this is trying
-if isapnptools can see both cards or just one.
-
-NOTE! Don't enable the SM Games option (asked by the configuration program)
- if you are not 101% sure that your card is a Logitech Soundman Games
- (not a SM Wave or SM16).
-
-SB Clones
----------
-
-First of all: There are no SB16 clones. There are SB Pro clones with a
-16 bit mode which is not SB16 compatible. The most likely alternative is that
-the 16 bit mode means MSS/WSS.
-
-There are just a few fully 100% hardware SB or SB Pro compatible cards.
-I know just Thunderboard and SM Games. Other cards require some kind of
-hardware initialization before they become SB compatible. Check if your card
-was listed in the beginning of this file. In this case you should follow
-instructions for your card later in this file.
-
-For other not fully SB clones you may try initialization using DOS in
-the following way:
-
- - Boot DOS so that the card specific driver gets run.
- - Hit ctrl-alt-del (or use loadlin) to boot Linux. Don't
- switch off power or press the reset button.
- - If you use the same I/O, IRQ and DMA settings in Linux, the
- card should work.
-
-If your card is both SB and MSS compatible, I recommend using the MSS mode.
-Most cards of this kind are not able to work in the SB and the MSS mode
-simultaneously. Using the MSS mode provides 16 bit recording and playback.
-
-ProAudioSpectrum 16 and compatibles
------------------------------------
-
-PAS16 has a SB emulation chip which can be used together with the native
-(16 bit) mode of the card. To enable this emulation you should configure
-the driver to have SB support too (this has been changed since version
-3.5-beta9 of this driver).
-
-With current driver versions it's also possible to use PAS16 together with
-another SB compatible card. In this case you should configure SB support
-for the other card and to disable the SB emulation of PAS16 (there is a
-separate questions about this).
-
-With PAS16 you can use two audio device files at the same time. /dev/dsp (and
-/dev/audio) is connected to the 8/16 bit native codec and the /dev/dsp1 (and
-/dev/audio1) is connected to the SB emulation (8 bit mono only).
-
-Gravis Ultrasound
------------------
-
-There are many different revisions of the Ultrasound card (GUS). The
-earliest ones (pre 3.7) don't have a hardware mixer. With these cards
-the driver uses a software emulation for synth and pcm playbacks. It's
-also possible to switch some of the inputs (line in, mic) off by setting
-mixer volume of the channel level below 10%. For recording you have
-to select the channel as a recording source and to use volume above 10%.
-
-GUS 3.7 has a hardware mixer.
-
-GUS MAX and the 16 bit sampling daughtercard have a CS4231 codec chip which
-also contains a mixer.
-
-Configuring GUS is simple. Just enable the GUS support and GUS MAX or
-the 16 bit daughtercard if you have them. Note that enabling the daughter
-card disables GUS MAX driver.
-
-NOTE for owners of the 16 bit daughtercard: By default the daughtercard
-uses /dev/dsp (and /dev/audio). Command "ln -sf /dev/dsp1 /dev/dsp"
-selects the daughter card as the default device.
-
-With just the standard GUS enabled the configuration program prompts
-for the I/O, IRQ and DMA numbers for the card. Use the same values than
-with DOS.
-
-With the daughter card option enabled you will be prompted for the I/O,
-IRQ and DMA numbers for the daughter card. You have to use different I/O
-and DMA values than for the standard GUS. The daughter card permits
-simultaneous recording and playback. Use /dev/dsp (the daughtercard) for
-recording and /dev/dsp1 (GUS GF1) for playback.
-
-GUS MAX uses the same I/O address and IRQ settings than the original GUS
-(GUS MAX = GUS + a CS4231 codec). In addition an extra DMA channel may be used.
-Using two DMA channels permits simultaneous playback using two devices
-(dev/dsp0 and /dev/dsp1). The second DMA channel is required for
-full duplex audio.
-To enable the second DMA channels, give a valid DMA channel when the config
-program asks for the GUS MAX DMA (entering -1 disables the second DMA).
-Using 16 bit DMA channels (5,6 or 7) is recommended.
-
-If you have problems in recording with GUS MAX, you could try to use
-just one 8 bit DMA channel. Recording will not work with one DMA
-channel if it's a 16 bit one.
-
-Microphone input of GUS MAX is connected to mixer in little bit nonstandard
-way. There is actually two microphone volume controls. Normal "mic" controls
-only recording level. Mixer control "speaker" is used to control volume of
-microphone signal connected directly to line/speaker out. So just decrease
-volume of "speaker" if you have problems with microphone feedback.
-
-GUS ACE works too but any attempt to record or to use the MIDI port
-will fail.
-
-GUS PnP (with RAM) is partially supported but it needs to be initialized using
-DOS or isapnptools before starting the driver.
-
-MPU401 and Windows Sound System
--------------------------------
-
-Again. Don't enable these options in case your card is listed
-somewhere else in this file.
-
-Configuring these cards is obvious (or it should be). With MSS
-you should probably enable the OPL3 synth also since
-most MSS compatible cards have it. However check that this is true
-before enabling OPL3.
-
-Sound driver supports more than one MPU401 compatible cards at the same time
-but the config program asks config info for just the first of them.
-Adding the second or third MPU interfaces must be done manually by
-editing sound/local.h (after running the config program). Add defines for
-MPU2_BASE & MPU2_IRQ (and MPU3_BASE & MPU3_IRQ) to the file.
-
-CAUTION!
-
-The default I/O base of Adaptec AHA-1542 SCSI controller is 0x330 which
-is also the default of the MPU401 driver. Don't configure the sound driver to
-use 0x330 as the MPU401 base if you have a AHA1542. The kernel will not boot
-if you make this mistake.
-
-PSS
----
-
-Even the PSS cards are compatible with SB, MSS and MPU401, you must not
-enable these options when configuring the driver. The configuration
-program handles these options itself. (You may use the SB, MPU and MSS options
-together with PSS if you have another card on the system).
-
-The PSS driver enables MSS and MPU401 modes of the card. SB is not enabled
-since it doesn't work concurrently with MSS. The driver loads also a
-DSP algorithm which is used to for the general MIDI emulation. The
-algorithm file (.ld) is read by the config program and written to a
-file included when the pss.c is compiled. For this reason the config
-program asks if you want to download the file. Use the genmidi.ld file
-distributed with the DOS/Windows drivers of the card (don't use the mt32.ld).
-With some cards the file is called 'synth.ld'. You must have access to
-the file when configuring the driver. The easiest way is to mount the DOS
-partition containing the file with Linux.
-
-It's possible to load your own DSP algorithms and run them with the card.
-Look at the directory pss_test of snd-util-3.0.tar.gz for more info.
-
-AudioTrix Pro
--------------
-
-You have to enable the OPL3 and SB (not SB Pro or SB16) drivers in addition
-to the native AudioTrix driver. Don't enable MSS or MPU drivers.
-
-Configuring ATP is little bit tricky since it uses so many I/O, IRQ and
-DMA numbers. Using the same values than with DOS/Win is a good idea. Don't
-attempt to use the same IRQ or DMA channels twice.
-
-The SB mode of ATP is implemented so the ATP driver just enables SB
-in the proper address. The SB driver handles the rest. You have to configure
-both the SB driver and the SB mode of ATP to use the same IRQ, DMA and I/O
-settings.
-
-Also the ATP has a microcontroller for the General MIDI emulation (OPL4).
-For this reason the driver asks for the name of a file containing the
-microcode (TRXPRO.HEX). This file is usually located in the directory
-where the DOS drivers were installed. You must have access to this file
-when configuring the driver.
-
-If you have the effects daughtercard, it must be initialized by running
-the setfx program of snd-util-3.0.tar.gz package. This step is not required
-when using the (future) binary distribution version of the driver.
-
-Ensoniq SoundScape
-------------------
-
-NOTE! The new PnP SoundScape is not supported yet. Soundscape compatible
- cards made by Reveal don't work with Linux. They use older revision
- of the Soundscape chipset which is not fully compatible with
- newer cards made by Ensoniq.
-
-The SoundScape driver handles initialization of MSS and MPU supports
-itself so you don't need to enable other drivers than SoundScape
-(enable also the /dev/dsp, /dev/sequencer and MIDI supports).
-
-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-!!!!! !!!!
-!!!!! NOTE! Before version 3.5-beta6 there WERE two sets of audio !!!!
-!!!!! device files (/dev/dsp0 and /dev/dsp1). The first one WAS !!!!
-!!!!! used only for card initialization and the second for audio !!!!
-!!!!! purposes. It WAS required to change /dev/dsp (a symlink) to !!!!
-!!!!! point to /dev/dsp1. !!!!
-!!!!! !!!!
-!!!!! This is not required with OSS versions 3.5-beta6 and later !!!!
-!!!!! since there is now just one audio device file. Please !!!!
-!!!!! change /dev/dsp to point back to /dev/dsp0 if you are !!!!
-!!!!! upgrading from an earlier driver version using !!!!
-!!!!! (cd /dev;rm dsp;ln -s dsp0 dsp). !!!!
-!!!!! !!!!
-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
-
-The configuration program asks one DMA channel and two interrupts. One IRQ
-and one DMA is used by the MSS codec. The second IRQ is required for the
-MPU401 mode (you have to use different IRQs for both purposes).
-There were earlier two DMA channels for SoundScape but the current driver
-version requires just one.
-
-The SoundScape card has a Motorola microcontroller which must initialized
-_after_ boot (the driver doesn't initialize it during boot).
-The initialization is done by running the 'ssinit' program which is
-distributed in the snd-util-3.0.tar.gz package. You have to edit two
-defines in the ssinit.c and then compile the program. You may run ssinit
-manually (after each boot) or add it to /etc/rc.d/rc.local.
-
-The ssinit program needs the microcode file that comes with the DOS/Windows
-driver of the card. You will need to use version 1.30.00 or later
-of the microcode file (sndscape.co0 or sndscape.co1 depending on
-your card model). THE OLD sndscape.cod WILL NOT WORK. IT WILL HANG YOUR
-MACHINE. The only way to get the new microcode file is to download
-and install the DOS/Windows driver from ftp://ftp.ensoniq.com/pub.
-
-Then you have to select the proper microcode file to use: soundscape.co0
-is the right one for most cards and sndscape.co1 is for few (older) cards
-made by Reveal and/or Spea. The driver has capability to detect the card
-version during boot. Look at the boot log messages in /var/adm/messages
-and locate the sound driver initialization message for the SoundScape
-card. If the driver displays string <Ensoniq Soundscape (old)>, you have
-an old card and you will need to use sndscape.co1. For other cards use
-soundscape.co0. New Soundscape revisions such as Elite and PnP use
-code files with higher numbers (.co2, .co3, etc.).
-
-NOTE! Ensoniq Soundscape VIVO is not compatible with other Soundscape cards.
- Currently it's possible to use it in Linux only with OSS/Linux
- drivers.
-
-Check /var/adm/messages after running ssinit. The driver prints
-the board version after downloading the microcode file. That version
-number must match the number in the name of the microcode file (extension).
-
-Running ssinit with a wrong version of the sndscape.co? file is not
-dangerous as long as you don't try to use a file called sndscape.cod.
-If you have initialized the card using a wrong microcode file (sounds
-are terrible), just modify ssinit.c to use another microcode file and try
-again. It's possible to use an earlier version of sndscape.co[01] but it
-may sound weird.
-
-MAD16 (Pro) and Mozart
-----------------------
-
-You need to enable just the MAD16 /Mozart support when configuring
-the driver. _Don't_ enable SB, MPU401 or MSS. However you will need the
-/dev/audio, /dev/sequencer and MIDI supports.
-
-Mozart and OPTi 82C928 (the original MAD16) chips don't support
-MPU401 mode so enter just 0 when the configuration program asks the
-MPU/MIDI I/O base. The MAD16 Pro (OPTi 82C929) and 82C930 chips have MPU401
-mode.
-
-TB Tropez is based on the 82C929 chip. It has two MIDI ports.
-The one connected to the MAD16 chip is the second one (there is a second
-MIDI connector/pins somewhere??). If you have not connected the second MIDI
-port, just disable the MIDI port of MAD16. The 'Maui' compatible synth of
-Tropez is jumper configurable and not connected to the MAD16 chip (the
-Maui driver can be used with it).
-
-Some MAD16 based cards may cause feedback, whistle or terrible noise if the
-line3 mixer channel is turned too high. This happens at least with Shuttle
-Sound System. Current driver versions set volume of line3 low enough so
-this should not be a problem.
-
-If you have a MAD16 card which have an OPL4 (FM + Wave table) synthesizer
-chip (_not_ an OPL3), you have to append a line containing #define MAD16_OPL4
-to the file linux/drivers/sound/local.h (after running make config).
-
-MAD16 cards having a CS4231 codec support full duplex mode. This mode
-can be enabled by configuring the card to use two DMA channels. Possible
-DMA channel pairs are: 0&1, 1&0 and 3&0.
-
-NOTE! Cards having an OPTi 82C924/82C925 chip work with OSS/Free only in
-non-PnP mode (usually jumper selectable). The PnP mode is supported only
-by OSS/Linux.
-
-MV Jazz (ProSonic)
-------------------
-
-The Jazz16 driver is just a hack made to the SB Pro driver. However it works
-fairly well. You have to enable SB, SB Pro (_not_ SB16) and MPU401 supports
-when configuring the driver. The configuration program asks later if you
-want support for MV Jazz16 based cards (after asking SB base address). Answer
-'y' here and the driver asks the second (16 bit) DMA channel.
-
-The Jazz16 driver uses the MPU401 driver in a way which will cause
-problems if you have another MPU401 compatible card. In this case you must
-give address of the Jazz16 based MPU401 interface when the config
-program prompts for the MPU401 information. Then look at the MPU401
-specific section for instructions about configuring more than one MPU401 cards.
-
-Logitech Soundman Wave
-----------------------
-
-Read the above MV Jazz specific instructions first.
-
-The Logitech SoundMan Wave (don't confuse this with the SM16 or SM Games) is
-a MV Jazz based card which has an additional OPL4 based wave table
-synthesizer. The OPL4 chip is handled by an on board microcontroller
-which must be initialized during boot. The config program asks if
-you have a SM Wave immediately after asking the second DMA channel of jazz16.
-If you answer 'y', the config program will ask name of the file containing
-code to be loaded to the microcontroller. The file is usually called
-MIDI0001.BIN and it's located in the DOS/Windows driver directory. The file
-may also be called as TSUNAMI.BIN or something else (older cards?).
-
-The OPL4 synth will be inaccessible without loading the microcontroller code.
-
-Also remember to enable SB MPU401 support if you want to use the OPL4 mode.
-(Don't enable the 'normal' MPU401 device as with some earlier driver
-versions (pre 3.5-alpha8)).
-
-NOTE! Don't answer 'y' when the driver asks about SM Games support
- (the next question after the MIDI0001.BIN name). However
- answering 'y' doesn't cause damage your computer so don't panic.
-
-Sound Galaxies
---------------
-
-There are many different Sound Galaxy cards made by Aztech. The 8 bit
-ones are fully SB or SB Pro compatible and there should be no problems
-with them.
-
-The older 16 bit cards (SG Pro16, SG NX Pro16, Nova and Lyra) have
-an EEPROM chip for storing the configuration data. There is a microcontroller
-which initializes the card to match the EEPROM settings when the machine
-is powered on. These cards actually behave just like they have jumpers
-for all of the settings. Configure driver for MSS, MPU, SB/SB Pro and OPL3
-supports with these cards.
-
-There are some new Sound Galaxies in the market. I have no experience with
-them so read the card's manual carefully.
-
-ESS ES1688 and ES688 'AudioDrive' based cards
----------------------------------------------
-
-Support for these two ESS chips is embedded in the SB driver.
-Configure these cards just like SB. Enable the 'SB MPU401 MIDI port'
-if you want to use MIDI features of ES1688. ES688 doesn't have MPU mode
-so you don't need to enable it (the driver uses normal SB MIDI automatically
-with ES688).
-
-NOTE! ESS cards are not compatible with MSS/WSS so don't worry if MSS support
-of OSS doesn't work with it.
-
-There are some ES1688/688 based sound cards and (particularly) motherboards
-which use software configurable I/O port relocation feature of the chip.
-This ESS proprietary feature is supported only by OSS/Linux.
-
-There are ES1688 based cards which use different interrupt pin assignment than
-recommended by ESS (5, 7, 9/2 and 10). In this case all IRQs don't work.
-At least a card called (Pearl?) Hypersound 16 supports IRQ 15 but it doesn't
-work.
-
-ES1868 is a PnP chip which is (supposed to be) compatible with ESS1688
-probably works with OSS/Free after initialization using isapnptools.
-
-Reveal cards
-------------
-
-There are several different cards made/marketed by Reveal. Some of them
-are compatible with SoundScape and some use the MAD16 chip. You may have
-to look at the card and try to identify its origin.
-
-Diamond
--------
-
-The oldest (Sierra Aria based) sound cards made by Diamond are not supported
-(they may work if the card is initialized using DOS). The recent (LX?)
-models are based on the MAD16 chip which is supported by the driver.
-
-Audio Excel DSP16
------------------
-
-Support for this card is currently not functional. A new driver for it
-should be available later this year.
-
-PCMCIA cards
-------------
-
-Sorry, can't help. Some cards may work and some don't.
-
-TI TM4000M notebooks
---------------------
-
-These computers have a built in sound support based on the Jazz chipset.
-Look at the instructions for MV Jazz (above). It's also important to note
-that there is something wrong with the mouse port and sound at least on
-some TM models. Don't enable the "C&T 82C710 mouse port support" when
-configuring Linux. Having it enabled is likely to cause mysterious problems
-and kernel failures when sound is used.
-
-miroSOUND
----------
-
-The miroSOUND PCM1-pro, PCM12 and PCM20 radio has been used
-successfully. These cards are based on the MAD16, OPL4, and CS4231A chips
-and everything said in the section about MAD16 cards applies here,
-too. The only major difference between the PCMxx and other MAD16 cards
-is that instead of the mixer in the CS4231 codec a separate mixer
-controlled by an on-board 80C32 microcontroller is used. Control of
-the mixer takes place via the ACI (miro's audio control interface)
-protocol that is implemented in a separate lowlevel driver. Make sure
-you compile this ACI driver together with the normal MAD16 support
-when you use a miroSOUND PCMxx card. The ACI mixer is controlled by
-/dev/mixer and the CS4231 mixer by /dev/mixer1 (depends on load
-time). Only in special cases you want to change something regularly on
-the CS4231 mixer.
-
-The miroSOUND PCM12 and PCM20 radio is capable of full duplex
-operation (simultaneous PCM replay and recording), which allows you to
-implement nice real-time signal processing audio effect software and
-network telephones. The ACI mixer has to be switched into the "solo"
-mode for duplex operation in order to avoid feedback caused by the
-mixer (input hears output signal). You can de-/activate this mode
-through toggling the record button for the wave controller with an
-OSS-mixer.
-
-The PCM20 contains a radio tuner, which is also controlled by
-ACI. This radio tuner is supported by the ACI driver together with the
-miropcm20.o module. Also the 7-band equalizer is integrated
-(limited by the OSS-design). Development has started and maybe
-finished for the RDS decoder on this card, too. You will be able to
-read RadioText, the Programme Service name, Programme TYpe and
-others. Even the v4l radio module benefits from it with a refined
-strength value. See aci.[ch] and miropcm20*.[ch] for more details.
-
-The following configuration parameters have worked fine for the PCM12
-in Markus Kuhn's system, many other configurations might work, too:
-CONFIG_MAD16_BASE=0x530, CONFIG_MAD16_IRQ=11, CONFIG_MAD16_DMA=3,
-CONFIG_MAD16_DMA2=0, CONFIG_MAD16_MPU_BASE=0x330, CONFIG_MAD16_MPU_IRQ=10,
-DSP_BUFFSIZE=65536, SELECTED_SOUND_OPTIONS=0x00281000.
-
-Bas van der Linden is using his PCM1-pro with a configuration that
-differs in: CONFIG_MAD16_IRQ=7, CONFIG_MAD16_DMA=1, CONFIG_MAD16_MPU_IRQ=9
-
-Compaq Deskpro XL
------------------
-
-The builtin sound hardware of Compaq Deskpro XL is now supported.
-You need to configure the driver with MSS and OPL3 supports enabled.
-In addition you need to manually edit linux/drivers/sound/local.h and
-to add a line containing "#define DESKPROXL" if you used
-make menuconfig/xconfig.
-
-Others?
--------
-
-Since there are so many different sound cards, it's likely that I have
-forgotten to mention many of them. Please inform me if you know yet another
-card which works with Linux, please inform me (or is anybody else
-willing to maintain a database of supported cards (just like in XF86)?).
-
-Cards not supported yet
-=======================
-
-Please check the version of sound driver you are using before
-complaining that your card is not supported. It's possible you are
-using a driver version which was released months before your card was
-introduced.
-
-First of all, there is an easy way to make most sound cards work with Linux.
-Just use the DOS based driver to initialize the card to a known state, then use
-loadlin.exe to boot Linux. If Linux is configured to use the same I/O, IRQ and
-DMA numbers as DOS, the card could work.
-(ctrl-alt-del can be used in place of loadlin.exe but it doesn't work with
-new motherboards). This method works also with all/most PnP sound cards.
-
-Don't get fooled with SB compatibility. Most cards are compatible with
-SB but that may require a TSR which is not possible with Linux. If
-the card is compatible with MSS, it's a better choice. Some cards
-don't work in the SB and MSS modes at the same time.
-
-Then there are cards which are no longer manufactured and/or which
-are relatively rarely used (such as the 8 bit ProAudioSpectrum
-models). It's extremely unlikely that such cards ever get supported.
-Adding support for a new card requires much work and increases time
-required in maintaining the driver (some changes need to be done
-to all low level drivers and be tested too, maybe with multiple
-operating systems). For this reason I have made a decision to not support
-obsolete cards. It's possible that someone else makes a separately
-distributed driver (diffs) for the card.
-
-Writing a driver for a new card is not possible if there are no
-programming information available about the card. If you don't
-find your new card from this file, look from the home page
-(http://www.opensound.com/ossfree). Then please contact
-manufacturer of the card and ask if they have (or are willing to)
-released technical details of the card. Do this before contacting me. I
-can only answer 'no' if there are no programming information available.
-
-I have made decision to not accept code based on reverse engineering
-to the driver. There are three main reasons: First I don't want to break
-relationships to sound card manufacturers. The second reason is that
-maintaining and supporting a driver without any specs will be a pain.
-The third reason is that companies have freedom to refuse selling their
-products to other than Windows users.
-
-Some companies don't give low level technical information about their
-products to public or at least their require signing a NDA. It's not
-possible to implement a freeware driver for them. However it's possible
-that support for such cards become available in the commercial version
-of this driver (see http://www.4Front-tech.com/oss.html for more info).
-
-There are some common audio chipsets that are not supported yet. For example
-Sierra Aria and IBM Mwave. It's possible that these architectures
-get some support in future but I can't make any promises. Just look
-at the home page (http://www.opensound.com/ossfree/)
-for latest info.
-
-Information about unsupported sound cards and chipsets is welcome as well
-as free copies of sound cards, SDKs and operating systems.

-If you have any corrections and/or comments, please contact me.

-Building a modular sound driver
-================================
-
- The following information is current as of linux-2.1.85. Check the other
-readme files, especially README.OSS, for information not specific to
-making sound modular.
-
- First, configure your kernel. This is an idea of what you should be
-setting in the sound section:
-
-<M> Sound card support
-
-<M> 100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support
-
- I have SoundBlaster. Select your card from the list.
-
-<M> Generic OPL2/OPL3 FM synthesizer support
-<M> FM synthesizer (YM3812/OPL-3) support
-
- If you don't set these, you will probably find you can play .wav files
-but not .midi. As the help for them says, set them unless you know your
-card does not use one of these chips for FM support.
-
- Once you are configured, make zlilo, modules, modules_install; reboot.
-Note that it is no longer necessary or possible to configure sound in the
-drivers/sound dir. Now one simply configures and makes one's kernel and
-modules in the usual way.
-
- Then, add to your /etc/modprobe.d/oss.conf something like:
-
-alias char-major-14-* sb
-install sb /sbin/modprobe -i sb && /sbin/modprobe adlib_card
-options sb io=0x220 irq=7 dma=1 dma16=5 mpu_io=0x330
-options adlib_card io=0x388 # FM synthesizer
-
- Alternatively, if you have compiled in kernel level ISAPnP support:
-
-alias char-major-14 sb
-softdep sb post: adlib_card
-options adlib_card io=0x388
-
- The effect of this is that the sound driver and all necessary bits and
-pieces autoload on demand, assuming you use kerneld (a sound choice) and
-autoclean when not in use. Also, options for the device drivers are
-set. They will not work without them. Change as appropriate for your card.
-If you are not yet using the very cool kerneld, you will have to "modprobe
--k sb" yourself to get things going. Eventually things may be fixed so
-that this kludgery is not necessary; for the time being, it seems to work
-well.
-
- Replace 'sb' with the driver for your card, and give it the right
-options. To find the filename of the driver, look in
-/lib/modules/<kernel-version>/misc. Mine looks like:
-
-adlib_card.o # This is the generic OPLx driver
-opl3.o # The OPL3 driver
-sb.o # <<The SoundBlaster driver. Yours may differ.>>
-sound.o # The sound driver
-uart401.o # Used by sb, maybe other cards
-
- Whichever card you have, try feeding it the options that would be the
-default if you were making the driver wired, not as modules. You can
-look at function referred to by module_init() for the card to see what
-args are expected.
-
- Note that at present there is no way to configure the io, irq and other
-parameters for the modular drivers as one does for the wired drivers.. One
-needs to pass the modules the necessary parameters as arguments, either
-with /etc/modprobe.d/*.conf or with command-line args to modprobe, e.g.
-
-modprobe sb io=0x220 irq=7 dma=1 dma16=5 mpu_io=0x330
-modprobe adlib_card io=0x388
-
- recommend using /etc/modprobe.d/*.conf.
-
-Persistent DMA Buffers:
-
-The sound modules normally allocate DMA buffers during open() and
-deallocate them during close(). Linux can often have problems allocating
-DMA buffers for ISA cards on machines with more than 16MB RAM. This is
-because ISA DMA buffers must exist below the 16MB boundary and it is quite
-possible that we can't find a large enough free block in this region after
-the machine has been running for any amount of time. The way to avoid this
-problem is to allocate the DMA buffers during module load and deallocate
-them when the module is unloaded. For this to be effective we need to load
-the sound modules right after the kernel boots, either manually or by an
-init script, and keep them around until we shut down. This is a little
-wasteful of RAM, but it guarantees that sound always works.
-
-To make the sound driver use persistent DMA buffers we need to pass the
-sound.o module a "dmabuf=1" command-line argument. This is normally done
-in /etc/modprobe.d/*.conf files like so:
-
-options sound dmabuf=1
-
-If you have 16MB or less RAM or a PCI sound card, this is wasteful and
-unnecessary. It is possible that machine with 16MB or less RAM will find
-this option useful, but if your machine is so memory-starved that it
-cannot find a 64K block free, you will be wasting even more RAM by keeping
-the sound modules loaded and the DMA buffers allocated when they are not
-needed. The proper solution is to upgrade your RAM. But you do also have
-this improper solution as well. Use it wisely.
-
- I'm afraid I know nothing about anything but my setup, being more of a
-text-mode guy anyway. If you have options for other cards or other helpful
-hints, send them to me, Jim Bray, jb@as220.org, http://as220.org/jb.

-Legacy audio driver for YMF7xx PCI cards.
-
-
-FIRST OF ALL
-============
-
- This code references YAMAHA's sample codes and data sheets.
- I respect and thank for all people they made open the information
- about YMF7xx cards.
-
- And this codes heavily based on Jeff Garzik <jgarzik@pobox.com>'s
- old VIA 82Cxxx driver (via82cxxx.c). I also respect him.
-
-
-DISCLIMER
-=========
-
- This driver is currently at early ALPHA stage. It may cause serious
- damage to your computer when used.
- PLEASE USE IT AT YOUR OWN RISK.
-
-
-ABOUT THIS DRIVER
-=================
-
- This code enables you to use your YMF724[A-F], YMF740[A-C], YMF744, YMF754
- cards. When enabled, your card acts as "SoundBlaster Pro" compatible card.
- It can only play 22.05kHz / 8bit / Stereo samples, control external MIDI
- port.
- If you want to use your card as recent "16-bit" card, you should use
- Alsa or OSS/Linux driver. Of course you can write native PCI driver for
- your cards :)
-
-
-USAGE
-=====
-
- # modprobe ymfsb (options)
-
-
-OPTIONS FOR MODULE
-==================
-
- io : SB base address (0x220, 0x240, 0x260, 0x280)
- synth_io : OPL3 base address (0x388, 0x398, 0x3a0, 0x3a8)
- dma : DMA number (0,1,3)
- master_volume: AC'97 PCM out Vol (0-100)
- spdif_out : SPDIF-out flag (0:disable 1:enable)
-
- These options will change in future...
-
-
-FREQUENCY
-=========
-
- When playing sounds via this driver, you will hear its pitch is slightly
- lower than original sounds. Since this driver recognizes your card acts
- with 21.739kHz sample rates rather than 22.050kHz (I think it must be
- hardware restriction). So many players become tone deafness.
- To prevent this, you should express some options to your sound player
- that specify correct sample frequency. For example, to play your MP3 file
- correctly with mpg123, specify the frequency like following:
-
- % mpg123 -r 21739 foo.mp3
-
-
-SPDIF OUT
-=========
-
- With installing modules with option 'spdif_out=1', you can enjoy your
- sounds from SPDIF-out of your card (if it had).
- Its Fs is fixed to 48kHz (It never means the sample frequency become
- up to 48kHz. All sounds via SPDIF-out also 22kHz samples). So your
- digital-in capable components has to be able to handle 48kHz Fs.

-Documentation for the SoundPro CMI8330 extensions in the WSS driver (ad1848.o)
-------------------------------------------------------------------------------
-
-( Be sure to read Documentation/sound/oss/CMI8330 too )
-
-Ion Badulescu, ionut@cs.columbia.edu
-February 24, 1999
-
-(derived from the OPL3-SA2 documentation by Scott Murray)
-
-The SoundPro CMI8330 (ISA) is a chip usually found on some Taiwanese
-motherboards. The official name in the documentation is CMI8330, SoundPro
-is the nickname and the big inscription on the chip itself.
-
-The chip emulates a WSS as well as a SB16, but it has certain differences
-in the mixer section which require separate support. It also emulates an
-MPU401 and an OPL3 synthesizer, so you probably want to enable support
-for these, too.
-
-The chip identifies itself as an AD1848, but its mixer is significantly
-more advanced than the original AD1848 one. If your system works with
-either WSS or SB16 and you are having problems with some mixer controls
-(no CD audio, no line-in, etc), you might want to give this driver a try.
-Detection should work, but it hasn't been widely tested, so it might still
-mis-identify the chip. You can still force soundpro=1 in the modprobe
-parameters for ad1848. Please let me know if it happens to you, so I can
-adjust the detection routine.
-
-The chip is capable of doing full-duplex, but since the driver sees it as an
-AD1848, it cannot take advantage of this. Moreover, the full-duplex mode is
-not achievable through the WSS interface, b/c it needs a dma16 line which is
-assigned only to the SB16 subdevice (with isapnp). Windows documentation
-says the user must use WSS Playback and SB16 Recording for full-duplex, so
-it might be possible to do the same thing under Linux. You can try loading
-up both ad1848 and sb then use one for playback and the other for
-recording. I don't know if this works, b/c I haven't tested it. Anyway, if
-you try it, be very careful: the SB16 mixer *mostly* works, but certain
-settings can have unexpected effects. Use the WSS mixer for best results.
-
-There is also a PCI SoundPro chip. I have not seen this chip, so I have
-no idea if the driver will work with it. I suspect it won't.
-
-As with PnP cards, some configuration is required. There are two ways
-of doing this. The most common is to use the isapnptools package to
-initialize the card, and use the kernel module form of the sound
-subsystem and sound drivers. Alternatively, some BIOS's allow manual
-configuration of installed PnP devices in a BIOS menu, which should
-allow using the non-modular sound drivers, i.e. built into the kernel.
-Since in this latter case you cannot use module parameters, you will
-have to enable support for the SoundPro at compile time.
-
-The IRQ and DMA values can be any that are considered acceptable for a
-WSS. Assuming you've got isapnp all happy, then you should be able to
-do something like the following (which *must* match the isapnp/BIOS
-configuration):
-
-modprobe ad1848 io=0x530 irq=11 dma=0 soundpro=1
--and maybe-
-modprobe sb io=0x220 irq=5 dma=1 dma16=5
-
--then-
-modprobe mpu401 io=0x330 irq=9
-modprobe opl3 io=0x388
-
-If all goes well and you see no error messages, you should be able to
-start using the sound capabilities of your system. If you get an
-error message while trying to insert the module(s), then make
-sure that the values of the various arguments match what you specified
-in your isapnp configuration file, and that there is no conflict with
-another device for an I/O port or interrupt. Checking the contents of
-/proc/ioports and /proc/interrupts can be useful to see if you're
-butting heads with another device.
-
-If you do not see the chipset version message, and none of the other
-messages present in the system log are helpful, try adding 'debug=1'
-to the ad1848 parameters, email me the syslog results and I'll do
-my best to help.
-
-Lastly, if you're using modules and want to set up automatic module
-loading with kmod, the kernel module loader, here is the section I
-currently use in my conf.modules file:
-
-# Sound
-post-install sound modprobe -k ad1848; modprobe -k mpu401; modprobe -k opl3
-options ad1848 io=0x530 irq=11 dma=0
-options sb io=0x220 irq=5 dma=1 dma16=5
-options mpu401 io=0x330 irq=9
-options opl3 io=0x388
-
-The above ensures that ad1848 will be loaded whenever the sound system
-is being used.
-
-Good luck.
-
-Ion
-
-NOT REALLY TESTED:
-- recording
-- recording device selection
-- full-duplex
-
-TODO:
-- implement mixer support for surround, loud, digital CD switches.
-- come up with a scheme which allows recording volumes for each subdevice.
-This is a major OSS API change.

-Sound Blaster 16X Vibra addendum
---------------------------------
-by Marius Ilioaea <mariusi@protv.ro>
- Stefan Laudat <stefan@asit.ro>
-
-Sat Mar 6 23:55:27 EET 1999
-
- Hello again,
-
- Playing with a SB Vibra 16x soundcard we found it very difficult
-to setup because the kernel reported a lot of DMA errors and wouldn't
-simply play any sound.
- A good starting point is that the vibra16x chip full-duplex facility
-is neither still exploited by the sb driver found in the linux kernel
-(tried it with a 2.2.2-ac7), nor in the commercial OSS package (it reports
-it as half-duplex soundcard). Oh, I almost forgot, the RedHat sndconfig
-failed detecting it ;)
- So, the big problem still remains, because the sb module wants a
-8-bit and a 16-bit dma, which we could not allocate for vibra... it supports
-only two 8-bit dma channels, the second one will be passed to the module
-as a 16 bit channel, the kernel will yield about that but everything will
-be okay, trust us.
- The only inconvenient you may find is that you will have
-some sound playing jitters if you have HDD dma support enabled - but this
-will happen with almost all soundcards...
-
- A fully working isapnp.conf is just here:
-
-<snip here>
-
-(READPORT 0x0203)
-(ISOLATE PRESERVE)
-(IDENTIFY *)
-(VERBOSITY 2)
-(CONFLICT (IO FATAL)(IRQ FATAL)(DMA FATAL)(MEM FATAL)) # or WARNING
-# SB 16 and OPL3 devices
-(CONFIGURE CTL00f0/-1 (LD 0
-(INT 0 (IRQ 5 (MODE +E)))
-(DMA 0 (CHANNEL 1))
-(DMA 1 (CHANNEL 3))
-(IO 0 (SIZE 16) (BASE 0x0220))
-(IO 2 (SIZE 4) (BASE 0x0388))
-(NAME "CTL00f0/-1[0]{Audio }")
-(ACT Y)
-))
-
-# Joystick device - only if you need it :-/
-
-(CONFIGURE CTL00f0/-1 (LD 1
-(IO 0 (SIZE 1) (BASE 0x0200))
-(NAME "CTL00f0/-1[1]{Game }")
-(ACT Y)
-))
-(WAITFORKEY)
-
-<end of snipping>
-
- So, after a good kernel modules compilation and a 'depmod -a kernel_ver'
-you may want to:
-
-modprobe sb io=0x220 irq=5 dma=1 dma16=3
-
- Or, take the hard way:
-
-modprobe soundcore
-modprobe sound
-modprobe uart401
-modprobe sb io=0x220 irq=5 dma=1 dma16=3
-# do you need MIDI?
-modprobe opl3=0x388
-
- Just in case, the kernel sound support should be:
-
-CONFIG_SOUND=m
-CONFIG_SOUND_OSS=m
-CONFIG_SOUND_SB=m
-
- Enjoy your new noisy Linux box! ;)

-Intro
-=====
-
-people start bugging me about this with questions, looks like I
-should write up some documentation for this beast. That way I
-don't have to answer that much mails I hope. Yes, I'm lazy...
-
-
-You might have noticed that the bt878 grabber cards have actually
-_two_ PCI functions:
-
-$ lspci
-[ ... ]
-00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
-00:0a.1 Multimedia controller: Brooktree Corporation Bt878 (rev 02)
-[ ... ]
-
-The first does video, it is backward compatible to the bt848. The second
-does audio. btaudio is a driver for the second function. It's a sound
-driver which can be used for recording sound (and _only_ recording, no
-playback). As most TV cards come with a short cable which can be plugged
-into your sound card's line-in you probably don't need this driver if all
-you want to do is just watching TV...
-
-
-Driver Status
-=============
-
-Still somewhat experimental. The driver should work stable, i.e. it
-should'nt crash your box. It might not work as expected, have bugs,
-not being fully OSS API compliant, ...
-
-Latest versions are available from http://bytesex.org/bttv/, the
-driver is in the bttv tarball. Kernel patches might be available too,
-have a look at http://bytesex.org/bttv/listing.html.
-
-The chip knows two different modes. btaudio registers two dsp
-devices, one for each mode. They can not be used at the same time.
-
-
-Digital audio mode
-==================
-
-The chip gives you 16 bit stereo sound. The sample rate depends on
-the external source which feeds the bt878 with digital sound via I2S
-interface. There is a insmod option (rate) to tell the driver which
-sample rate the hardware uses (32000 is the default).
-
-One possible source for digital sound is the msp34xx audio processor
-chip which provides digital sound via I2S with 32 kHz sample rate. My
-Hauppauge board works this way.
-
-The Osprey-200 reportly gives you digital sound with 44100 Hz sample
-rate. It is also possible that you get no sound at all.
-
-
-analog mode (A/D)
-=================
-
-You can tell the driver to use this mode with the insmod option "analog=1".
-The chip has three analog inputs. Consequently you'll get a mixer device
-to control these.
-
-The analog mode supports mono only. Both 8 + 16 bit. Both are _signed_
-int, which is uncommon for the 8 bit case. Sample rate range is 119 kHz
-to 448 kHz. Yes, the number of digits is correct. The driver supports
-downsampling by powers of two, so you can ask for more usual sample rates
-like 44 kHz too.
-
-With my Hauppauge I get noisy sound on the second input (mapped to line2
-by the mixer device). Others get a useable signal on line1.
-
-
-some examples
-=============
-
-* read audio data from btaudio (dsp2), send to es1730 (dsp,dsp1):
- $ sox -w -r 32000 -t ossdsp /dev/dsp2 -t ossdsp /dev/dsp
-
-* read audio data from btaudio, send to esound daemon (which might be
- running on another host):
- $ sox -c 2 -w -r 32000 -t ossdsp /dev/dsp2 -t sw - | esdcat -r 32000
- $ sox -c 1 -w -r 32000 -t ossdsp /dev/dsp2 -t sw - | esdcat -m -r 32000

- How to try to survive an IBM Mwave under Linux SB drivers
-
-
-+ IBM have now released documentation of sorts and Torsten is busy
- trying to make the Mwave work. This is not however a trivial task.
-
-----------------------------------------------------------------------------
-
-OK, first thing - the IRQ problem IS a problem, whether the test is bypassed or
-not. It is NOT a Linux problem, but an MWAVE problem that is fixed with the
-latest MWAVE patches. So, in other words, don't bypass the test for MWAVES!
-
-I have Windows 95 on /dev/hda1, swap on /dev/hda2, and Red Hat 5 on /dev/hda3.
-
-The steps, then:
-
- Boot to Linux.
- Mount Windows 95 file system (assume mount point = /dos95).
- mkdir /dos95/linux
- mkdir /dos95/linux/boot
- mkdir /dos95/linux/boot/parms
-
- Copy the kernel, any initrd image, and loadlin to /dos95/linux/boot/.
-
- Reboot to Windows 95.
-
- Edit C:/msdos.sys and add or change the following:
-
- Logo=0
- BootGUI=0
-
- Note that msdos.sys is a text file but it needs to be made 'unhidden',
- readable and writable before it can be edited. This can be done with
- DOS' "attrib" command.
-
- Edit config.sys to have multiple config menus. I have one for windows 95 and
- five for Linux, like this:
-------------
-[menu]
-menuitem=W95, Windows 95
-menuitem=LINTP, Linux - ThinkPad
-menuitem=LINTP3, Linux - ThinkPad Console
-menuitem=LINDOC, Linux - Docked
-menuitem=LINDOC3, Linux - Docked Console
-menuitem=LIN1, Linux - Single User Mode
-REM menudefault=W95,10
-
-[W95]
-
-[LINTP]
-
-[LINDOC]
-
-[LINTP3]
-
-[LINDOC3]
-
-[LIN1]
-
-[COMMON]
-FILES=30
-REM Please read README.TXT in C:\MWW subdirectory before changing the DOS= statement.
-DOS=HIGH,UMB
-DEVICE=C:\MWW\MANAGER\MWD50430.EXE
-SHELL=c:\command.com /e:2048
--------------------
-
-The important things are the SHELL and DEVICE statements.
-
- Then change autoexec.bat. Basically everything in there originally should be
- done ONLY when Windows 95 is booted. Then you add new things specifically
- for Linux. Mine is as follows
-
----------------
-@ECHO OFF
-if "%CONFIG%" == "W95" goto W95
-
-REM
-REM Linux stuff
-REM
-SET MWPATH=C:\MWW\DLL;C:\MWW\MWGAMES;C:\MWW\DSP

-REM The following is used by DOS games to recognize Sound Blaster hardware.
-REM If hardware settings are changed, please change this line as well.
-REM See the Mwave README file for instructions.
-SET BLASTER=A220 I5 D1
-SET MWROOT=C:\MWW
-SET LIBPATH=C:\MWW\DLL
-SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;E:\ORAWIN95\BIN;f:\msdev\bin;e:\v30\bin.dbg;v:\devt\v30\bin;c:\JavaSDK\Bin;C:\MWW\DLL;
-SET INCLUDE=f:\MSDEV\INCLUDE;F:\MSDEV\MFC\INCLUDE
-SET LIB=F:\MSDEV\LIB;F:\MSDEV\MFC\LIB
-win
-
-------------------------
-
-Now build a file in c:\linux\boot\parms for each Linux config that you have.
-
-For example, my LINDOC3 config is for a docked Thinkpad at runlevel 3 with no
-initrd image, and has a parameter file named LINDOC3.PAR in c:\linux\boot\parms:
-
------------------------
-# LOADLIN @param_file image=other_image root=/dev/other
-#
-# Linux Console in docking station
-#
-c:\linux\boot\zImage.krn # First value must be filename of Linux kernel.
-root=/dev/hda3 # device which gets mounted as root FS
-ro # Other kernel arguments go here.
-apm=off
-doc=yes
-3
------------------------
-
-The doc=yes parameter is an environment variable used by my init scripts, not
-a kernel argument.
-
-However, the apm=off parameter IS a kernel argument! APM, at least in my setup,
-causes the kernel to crash when loaded via loadlin (but NOT when loaded via
-LILO). The APM stuff COULD be forced out of the kernel via the kernel compile
-options. Instead, I got an unofficial patch to the APM drivers that allows them
-to be dynamically deactivated via kernel arguments. Whatever you chose to
-document, APM, it seems, MUST be off for setups like mine.
-
-Now make sure C:\MWW\MWCONFIG.REF looks like this:
-
-----------------------
-[NativeDOS]
-Default=SB1.5
-SBInputSource=CD
-SYNTH=FM
-QSound=OFF
-Reverb=OFF
-Chorus=OFF
-ReverbDepth=5
-ChorusDepth=5
-SBInputVolume=5
-SBMainVolume=10
-SBWaveVolume=10
-SBSynthVolume=10
-WaveTableVolume=10
-AudioPowerDriver=ON
-
-[FastCFG]
-Show=No
-HideOption=Off
------------------------------
-
-OR the Default= line COULD be
-
-Default=SBPRO
-
-Reboot to Windows 95 and choose Linux. When booted, use sndconfig to configure
-the sound modules and voilà - ThinkPad sound with Linux.
-
-Now the gotchas - you can either have CD sound OR Mixers but not both. That's a
-problem with the SB1.5 (CD sound) or SBPRO (Mixers) settings. No one knows why
-this is!
-
-For some reason MPEG3 files, when played through mpg123, sound like they
-are playing at 1/8th speed - not very useful! If you have ANY insight
-on why this second thing might be happening, I would be grateful.

Options
~~~~~~~
-Some options can be set in the source text (in arch/i386/boot/video.S).
-All of them are simple #define's -- change them to #undef's when you want to
-switch them off. Currently supported:
-
-CONFIG_VIDEO_SVGA - enables autodetection of SVGA cards. This is switched
-off by default as it's a bit unreliable due to terribly bad PC design. If you
-really want to have the adapter autodetected (maybe in case the ``scan`` feature
-doesn't work on your machine), switch this on and don't cry if the results
-are not completely sane. In case you really need this feature, please drop me
-a mail as I think of removing it some day.
-
-CONFIG_VIDEO_VESA - enables autodetection of VESA modes. If it doesn't work
-on your machine (or displays a "Error: Scanning of VESA modes failed" message),
-you can switch it off and report as a bug.
-
-CONFIG_VIDEO_COMPACT - enables compacting of the video mode list. If there
-are more modes with the same screen size, only the first one is kept (see above
-for more info on mode ordering). However, in very strange cases it's possible
-that the first "version" of the mode doesn't work although some of the others
-do -- in this case turn this switch off to see the rest.
-
-CONFIG_VIDEO_RETAIN - enables retaining of screen contents when switching
-video modes. Works only with some boot loaders which leave enough room for the
-buffer. (If you have old LILO, you can adjust heap_end_ptr and loadflags
-in setup.S, but it's better to upgrade the boot loader...)
-
-CONFIG_VIDEO_LOCAL - enables inclusion of "local modes" in the list. The
-local modes are added automatically to the beginning of the list not depending
-on hardware configuration. The local modes are listed in the source text after
-the "local_mode_table:" line. The comment before this line describes the format
-of the table (which also includes a video card name to be displayed on the
-top of the menu).
-
-CONFIG_VIDEO_400_HACK - force setting of 400 scan lines for standard VGA
-modes. This option is intended to be used on certain buggy BIOSes which draw
-some useless logo using font download and then fail to reset the correct mode.
-Don't use unless needed as it forces resetting the video card.
-
-CONFIG_VIDEO_GFX_HACK - includes special hack for setting of graphics modes
-to be used later by special drivers (e.g., 800x600 on IBM ThinkPad -- see
-ftp://ftp.phys.keio.ac.jp/pub/XFree86/800x600/XF86Configs/XF86Config.IBM_TP560).

+Using ftrace to hook to functions
+=================================

+
+Introduction
+============
+
+The ftrace infrastructure was originially created to attach callbacks to the
+beginning of functions in order to record and trace the flow of the kernel.
+But callbacks to the start of a function can have other use cases. Either
+for live kernel patching, or for security monitoring. This document describes
+how to use ftrace to implement your own function callbacks.
+
+
+The ftrace context
+==================
+
+WARNING: The ability to add a callback to almost any function within the
+kernel comes with risks. A callback can be called from any context
+(normal, softirq, irq, and NMI). Callbacks can also be called just before
+going to idle, during CPU bring up and takedown, or going to user space.
+This requires extra care to what can be done inside a callback. A callback
+can be called outside the protective scope of RCU.
+
+The ftrace infrastructure has some protections agains recursions and RCU
+but one must still be very careful how they use the callbacks.
+
+
+The ftrace_ops structure
+========================
+
+To register a function callback, a ftrace_ops is required. This structure
+is used to tell ftrace what function should be called as the callback
+as well as what protections the callback will perform and not require
+ftrace to handle.
+
+There is only one field that is needed to be set when registering
+an ftrace_ops with ftrace::
+
+.. code-block: c
+
+ struct ftrace_ops ops = {
+ .func = my_callback_func,
+ .flags = MY_FTRACE_FLAGS
+ .private = any_private_data_structure,
+ };
+
+Both .flags and .private are optional. Only .func is required.
+
+To enable tracing call::
+
+.. c:function:: register_ftrace_function(&ops);
+
+To disable tracing call::
+
+.. c:function:: unregister_ftrace_function(&ops);
+
+The above is defined by including the header::
+
+.. c:function:: #include <linux/ftrace.h>
+
+The registered callback will start being called some time after the
+register_ftrace_function() is called and before it returns. The exact time
+that callbacks start being called is dependent upon architecture and scheduling
+of services. The callback itself will have to handle any synchronization if it
+must begin at an exact moment.
+
+The unregister_ftrace_function() will guarantee that the callback is
+no longer being called by functions after the unregister_ftrace_function()
+returns. Note that to perform this guarantee, the unregister_ftrace_function()
+may take some time to finish.
+
+
+The callback function
+=====================
+
+The prototype of the callback function is as follows (as of v4.14)::
+
+.. code-block: c
+
+ void callback_func(unsigned long ip, unsigned long parent_ip,
+ struct ftrace_ops *op, struct pt_regs *regs);
+
+@ip
+ This is the instruction pointer of the function that is being traced.
+ (where the fentry or mcount is within the function)
+
+@parent_ip
+ This is the instruction pointer of the function that called the
+ the function being traced (where the call of the function occurred).
+
+@op
+ This is a pointer to ftrace_ops that was used to register the callback.
+ This can be used to pass data to the callback via the private pointer.
+
+@regs
+ If the FTRACE_OPS_FL_SAVE_REGS or FTRACE_OPS_FL_SAVE_REGS_IF_SUPPORTED
+ flags are set in the ftrace_ops structure, then this will be pointing
+ to the pt_regs structure like it would be if an breakpoint was placed
+ at the start of the function where ftrace was tracing. Otherwise it
+ either contains garbage, or NULL.
+
+
+The ftrace FLAGS
+================
+
+The ftrace_ops flags are all defined and documented in include/linux/ftrace.h.
+Some of the flags are used for internal infrastructure of ftrace, but the
+ones that users should be aware of are the following:
+
+FTRACE_OPS_FL_SAVE_REGS
+ If the callback requires reading or modifying the pt_regs
+ passed to the callback, then it must set this flag. Registering
+ a ftrace_ops with this flag set on an architecture that does not
+ support passing of pt_regs to the callback will fail.
+
+FTRACE_OPS_FL_SAVE_REGS_IF_SUPPORTED
+ Similar to SAVE_REGS but the registering of a
+ ftrace_ops on an architecture that does not support passing of regs
+ will not fail with this flag set. But the callback must check if
+ regs is NULL or not to determine if the architecture supports it.
+
+FTRACE_OPS_FL_RECURSION_SAFE
+ By default, a wrapper is added around the callback to
+ make sure that recursion of the function does not occur. That is,
+ if a function that is called as a result of the callback's execution
+ is also traced, ftrace will prevent the callback from being called
+ again. But this wrapper adds some overhead, and if the callback is
+ safe from recursion, it can set this flag to disable the ftrace
+ protection.
+
+ Note, if this flag is set, and recursion does occur, it could cause
+ the system to crash, and possibly reboot via a triple fault.
+
+ It is OK if another callback traces a function that is called by a
+ callback that is marked recursion safe. Recursion safe callbacks
+ must never trace any function that are called by the callback
+ itself or any nested functions that those functions call.
+
+ If this flag is set, it is possible that the callback will also
+ be called with preemption enabled (when CONFIG_PREEMPT is set),
+ but this is not guaranteed.
+
+FTRACE_OPS_FL_IPMODIFY
+ Requires FTRACE_OPS_FL_SAVE_REGS set. If the callback is to "hijack"
+ the traced function (have another function called instead of the
+ traced function), it requires setting this flag. This is what live
+ kernel patches uses. Without this flag the pt_regs->ip can not be
+ modified.
+
+ Note, only one ftrace_ops with FTRACE_OPS_FL_IPMODIFY set may be
+ registered to any given function at a time.
+
+FTRACE_OPS_FL_RCU
+ If this is set, then the callback will only be called by functions
+ where RCU is "watching". This is required if the callback function
+ performs any rcu_read_lock() operation.
+
+ RCU stops watching when the system goes idle, the time when a CPU
+ is taken down and comes back online, and when entering from kernel
+ to user space and back to kernel space. During these transitions,
+ a callback may be executed and RCU synchronization will not protect
+ it.
+
+
+Filtering which functions to trace
+==================================
+
+If a callback is only to be called from specific functions, a filter must be
+set up. The filters are added by name, or ip if it is known.
+
+.. code-block: c
+
+ int ftrace_set_filter(struct ftrace_ops *ops, unsigned char *buf,
+ int len, int reset);
+
+@ops
+ The ops to set the filter with
+
+@buf
+ The string that holds the function filter text.
+@len
+ The length of the string.
+
+@reset
+ Non-zero to reset all filters before applying this filter.
+
+Filters denote which functions should be enabled when tracing is enabled.
+If @buf is NULL and reset is set, all functions will be enabled for tracing.
+
+The @buf can also be a glob expression to enable all functions that
+match a specific pattern.
+
+See Filter Commands in :file:`Documentation/trace/ftrace.txt`.
+
+To just trace the schedule function::
+
+.. code-block: c
+
+ ret = ftrace_set_filter(&ops, "schedule", strlen("schedule"), 0);
+
+To add more functions, call the ftrace_set_filter() more than once with the
+@reset parameter set to zero. To remove the current filter set and replace it
+with new functions defined by @buf, have @reset be non-zero.
+
+To remove all the filtered functions and trace all functions::
+
+.. code-block: c
+
+ ret = ftrace_set_filter(&ops, NULL, 0, 1);
+
+
+Sometimes more than one function has the same name. To trace just a specific
+function in this case, ftrace_set_filter_ip() can be used.
+
+.. code-block: c
+
+ ret = ftrace_set_filter_ip(&ops, ip, 0, 0);
+
+Although the ip must be the address where the call to fentry or mcount is
+located in the function. This function is used by perf and kprobes that
+gets the ip address from the user (usually using debug info from the kernel).
+
+If a glob is used to set the filter, functions can be added to a "notrace"
+list that will prevent those functions from calling the callback.
+The "notrace" list takes precedence over the "filter" list. If the
+two lists are non-empty and contain the same functions, the callback will not
+be called by any function.
+
+An empty "notrace" list means to allow all functions defined by the filter
+to be traced.
+
+.. code-block: c
+
+ int ftrace_set_notrace(struct ftrace_ops *ops, unsigned char *buf,
+ int len, int reset);
+
+This takes the same parameters as ftrace_set_filter() but will add the
+functions it finds to not be traced. This is a separate list from the
+filter list, and this function does not modify the filter list.
+
+A non-zero @reset will clear the "notrace" list before adding functions
+that match @buf to it.
+
+Clearing the "notrace" list is the same as clearing the filter list
+
+.. code-block: c
+
+ ret = ftrace_set_notrace(&ops, NULL, 0, 1);
+
+The filter and notrace lists may be changed at any time. If only a set of
+functions should call the callback, it is best to set the filters before
+registering the callback. But the changes may also happen after the callback
+has been registered.
+
+If a filter is in place, and the @reset is non-zero, and @buf contains a
+matching glob to functions, the switch will happen during the time of
+the ftrace_set_filter() call. At no time will all functions call the callback.
+
+.. code-block: c
+
+ ftrace_set_filter(&ops, "schedule", strlen("schedule"), 1);
+
+ register_ftrace_function(&ops);
+
+ msleep(10);
+
+ ftrace_set_filter(&ops, "try_to_wake_up", strlen("try_to_wake_up"), 1);
+
+is not the same as:
+
+.. code-block: c
+
+ ftrace_set_filter(&ops, "schedule", strlen("schedule"), 1);
+
+ register_ftrace_function(&ops);
+
+ msleep(10);
+
+ ftrace_set_filter(&ops, NULL, 0, 1);
+
+ ftrace_set_filter(&ops, "try_to_wake_up", strlen("try_to_wake_up"), 0);
+
+As the latter will have a short time where all functions will call
+the callback, between the time of the reset, and the time of the
+new setting of the filter.

+When do you need to notify inside page table lock ?
+
+When clearing a pte/pmd we are given a choice to notify the event through
+(notify version of *_clear_flush call mmu_notifier_invalidate_range) under
+the page table lock. But that notification is not necessary in all cases.
+
+For secondary TLB (non CPU TLB) like IOMMU TLB or device TLB (when device use
+thing like ATS/PASID to get the IOMMU to walk the CPU page table to access a
+process virtual address space). There is only 2 cases when you need to notify
+those secondary TLB while holding page table lock when clearing a pte/pmd:
+
+ A) page backing address is free before mmu_notifier_invalidate_range_end()
+ B) a page table entry is updated to point to a new page (COW, write fault
+ on zero page, __replace_page(), ...)
+
+Case A is obvious you do not want to take the risk for the device to write to
+a page that might now be used by some completely different task.
+
+Case B is more subtle. For correctness it requires the following sequence to
+happen:
+ - take page table lock
+ - clear page table entry and notify ([pmd/pte]p_huge_clear_flush_notify())
+ - set page table entry to point to new page
+
+If clearing the page table entry is not followed by a notify before setting
+the new pte/pmd value then you can break memory model like C11 or C++11 for
+the device.
+
+Consider the following scenario (device use a feature similar to ATS/PASID):
+
+Two address addrA and addrB such that |addrA - addrB| >= PAGE_SIZE we assume
+they are write protected for COW (other case of B apply too).
+
+[Time N] --------------------------------------------------------------------
+CPU-thread-0 {try to write to addrA}
+CPU-thread-1 {try to write to addrB}
+CPU-thread-2 {}
+CPU-thread-3 {}
+DEV-thread-0 {read addrA and populate device TLB}
+DEV-thread-2 {read addrB and populate device TLB}
+[Time N+1] ------------------------------------------------------------------
+CPU-thread-0 {COW_step0: {mmu_notifier_invalidate_range_start(addrA)}}
+CPU-thread-1 {COW_step0: {mmu_notifier_invalidate_range_start(addrB)}}
+CPU-thread-2 {}
+CPU-thread-3 {}
+DEV-thread-0 {}
+DEV-thread-2 {}
+[Time N+2] ------------------------------------------------------------------
+CPU-thread-0 {COW_step1: {update page table to point to new page for addrA}}
+CPU-thread-1 {COW_step1: {update page table to point to new page for addrB}}
+CPU-thread-2 {}
+CPU-thread-3 {}
+DEV-thread-0 {}
+DEV-thread-2 {}
+[Time N+3] ------------------------------------------------------------------
+CPU-thread-0 {preempted}
+CPU-thread-1 {preempted}
+CPU-thread-2 {write to addrA which is a write to new page}
+CPU-thread-3 {}
+DEV-thread-0 {}
+DEV-thread-2 {}
+[Time N+3] ------------------------------------------------------------------
+CPU-thread-0 {preempted}
+CPU-thread-1 {preempted}
+CPU-thread-2 {}
+CPU-thread-3 {write to addrB which is a write to new page}
+DEV-thread-0 {}
+DEV-thread-2 {}
+[Time N+4] ------------------------------------------------------------------
+CPU-thread-0 {preempted}
+CPU-thread-1 {COW_step3: {mmu_notifier_invalidate_range_end(addrB)}}
+CPU-thread-2 {}
+CPU-thread-3 {}
+DEV-thread-0 {}
+DEV-thread-2 {}
+[Time N+5] ------------------------------------------------------------------
+CPU-thread-0 {preempted}
+CPU-thread-1 {}
+CPU-thread-2 {}
+CPU-thread-3 {}
+DEV-thread-0 {read addrA from old page}
+DEV-thread-2 {read addrB from new page}
+
+So here because at time N+2 the clear page table entry was not pair with a
+notification to invalidate the secondary TLB, the device see the new value for
+addrB before seing the new value for addrA. This break total memory ordering
+for the device.
+
+When changing a pte to write protect or to point to a new write protected page
+with same content (KSM) it is fine to delay the mmu_notifier_invalidate_range
+call to mmu_notifier_invalidate_range_end() outside the page table lock. This
+is true even if the thread doing the page table update is preempted right after
+releasing page table lock but before call mmu_notifier_invalidate_range_end().

+Kernel driver w1_ds28e17
+========================
+
+Supported chips:
+ * Maxim DS28E17 1-Wire-to-I2C Master Bridge
+
+supported family codes:
+ W1_FAMILY_DS28E17 0x19
+
+Author: Jan Kandziora <jjj@gmx.de>
+
+
+Description
+-----------
+The DS28E17 is a Onewire slave device which acts as an I2C bus master.
+
+This driver creates a new I2C bus for any DS28E17 device detected. I2C buses
+come and go as the DS28E17 devices come and go. I2C slave devices connected to
+a DS28E17 can be accessed by the kernel or userspace tools as if they were
+connected to a "native" I2C bus master.
+
+
+An udev rule like the following
+-------------------------------------------------------------------------------
+SUBSYSTEM=="i2c-dev", KERNEL=="i2c-[0-9]*", ATTRS{name}=="w1-19-*", \
+ SYMLINK+="i2c-$attr{name}"
+-------------------------------------------------------------------------------
+may be used to create stable /dev/i2c- entries based on the unique id of the
+DS28E17 chip.
+
+
+Driver parameters are:
+
+speed:
+ This sets up the default I2C speed a DS28E17 get configured for as soon
+ it is connected. The power-on default of the DS28E17 is 400kBaud, but
+ chips may come and go on the Onewire bus without being de-powered and
+ as soon the "w1_ds28e17" driver notices a freshly connected, or
+ reconnected DS28E17 device on the Onewire bus, it will re-apply this
+ setting.
+
+ Valid values are 100, 400, 900 [kBaud]. Any other value means to leave
+ alone the current DS28E17 setting on detect. The default value is 100.
+
+stretch:
+ This sets up the default stretch value used for freshly connected
+ DS28E17 devices. It is a multiplier used on the calculation of the busy
+ wait time for an I2C transfer. This is to account for I2C slave devices
+ which make heavy use of the I2C clock stretching feature and thus, the
+ needed timeout cannot be pre-calculated correctly. As the w1_ds28e17
+ driver checks the DS28E17's busy flag in a loop after the precalculated
+ wait time, it should be hardly needed to tweak this setting.
+
+ Leave it at 1 unless you get ETIMEDOUT errors and a "w1_slave_driver
+ 19-00000002dbd8: busy timeout" in the kernel log.
+
+ Valid values are 1 to 9. The default is 1.
+
+
+The driver creates sysfs files /sys/bus/w1/devices/19-<id>/speed and
+/sys/bus/w1/devices/19-<id>/stretch for each device, preloaded with the default
+settings from the driver parameters. They may be changed anytime. In addition a
+directory /sys/bus/w1/devices/19-<id>/i2c-<nnn> for the I2C bus master sysfs
+structure is created.
+
+
+See https://github.com/ianka/w1_ds28e17 for even more information.

bit in the page table entry that points to the next table. This allows the full

- * The V3 PCI interface chip in Integrator provides several windows from
- * local bus memory into the PCI memory areas. Unfortunately, there
- * are not really enough windows for our usage, therefore we reuse
- * one of the windows for access to PCI configuration space. The
- * memory map is as follows:
- *
- * Local Bus Memory Usage
- *
- * 40000000 - 4FFFFFFF PCI memory. 256M non-prefetchable
- * 50000000 - 5FFFFFFF PCI memory. 256M prefetchable
- * 60000000 - 60FFFFFF PCI IO. 16M
- * 61000000 - 61FFFFFF PCI Configuration. 16M
- *
- * There are three V3 windows, each described by a pair of V3 registers.
- * These are LB_BASE0/LB_MAP0, LB_BASE1/LB_MAP1 and LB_BASE2/LB_MAP2.
- * Base0 and Base1 can be used for any type of PCI memory access. Base2
- * can be used either for PCI I/O or for I20 accesses. By default, uHAL
- * uses this only for PCI IO space.
- *
- * Normally these spaces are mapped using the following base registers:
- *
- * Usage Local Bus Memory Base/Map registers used
- *
- * Mem 40000000 - 4FFFFFFF LB_BASE0/LB_MAP0
- * Mem 50000000 - 5FFFFFFF LB_BASE1/LB_MAP1
- * IO 60000000 - 60FFFFFF LB_BASE2/LB_MAP2
- * Cfg 61000000 - 61FFFFFF
- *
- * This means that I20 and PCI configuration space accesses will fail.
- * When PCI configuration accesses are needed (via the uHAL PCI
- * configuration space primitives) we must remap the spaces as follows:
- *
- * Usage Local Bus Memory Base/Map registers used
- *
- * Mem 40000000 - 4FFFFFFF LB_BASE0/LB_MAP0
- * Mem 50000000 - 5FFFFFFF LB_BASE0/LB_MAP0
- * IO 60000000 - 60FFFFFF LB_BASE2/LB_MAP2
- * Cfg 61000000 - 61FFFFFF LB_BASE1/LB_MAP1
- *
- * To make this work, the code depends on overlapping windows working.
- * The V3 chip translates an address by checking its range within
- * each of the BASE/MAP pairs in turn (in ascending register number
- * order). It will use the first matching pair. So, for example,
- * if the same address is mapped by both LB_BASE0/LB_MAP0 and
- * LB_BASE1/LB_MAP1, the V3 will use the translation from
- * LB_BASE0/LB_MAP0.
- *
- * To allow PCI Configuration space access, the code enlarges the
- * window mapped by LB_BASE0/LB_MAP0 from 256M to 512M. This occludes
- * the windows currently mapped by LB_BASE1/LB_MAP1 so that it can
- * be remapped for use by configuration cycles.
- *
- * At the end of the PCI Configuration space accesses,
- * LB_BASE1/LB_MAP1 is reset to map PCI Memory. Finally the window
- * mapped by LB_BASE0/LB_MAP0 is reduced in size from 512M to 256M to
- * reveal the now restored LB_BASE1/LB_MAP1 window.
- *
- * NOTE: We do not set up I2O mapping. I suspect that this is only
- * for an intelligent (target) device. Using I2O disables most of
- * the mappings into PCI memory.

- *
- * The MSW of the count is the negated number of active writers and waiting
- * lockers, and the LSW is the total number of active locks
- *
- * The lock count is initialized to 0 (no active and no waiting lockers).
- *
- * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an
- * uncontended lock. This can be determined because XADD returns the old value.
- * Readers increment by 1 and see a positive value when uncontended, negative
- * if there are writers (and maybe) readers waiting (in which case it goes to
- * sleep).
- *
- * The value of WAITING_BIAS supports up to 32766 waiting processes. This can
- * be extended to 65534 by manually checking the whole MSW rather than relying
- * on the S flag.
- *
- * The value of ACTIVE_BIAS supports up to 65535 active processes.
- *
- * This should be totally fair - if anything is waiting, a process that wants a
- * lock will go to the back of the queue. When the currently active lock is
- * released, if there's a writer at the front of the queue, then that and only
- * that will be woken up; if there's a bunch of consecutive readers at the
- * front, then they'll all be woken up, but no other readers will be.

+/*
+ * vdso2c - A vdso image preparation tool
+ * Copyright (c) 2014 Andy Lutomirski and others
+ * Licensed under the GPL v2
+ *
+ * vdso2c requires stripped and unstripped input. It would be trivial
+ * to fully strip the input in here, but, for reasons described below,
+ * we need to write a section table. Doing this is more or less
+ * equivalent to dropping all non-allocatable sections, but it's
+ * easier to let objcopy handle that instead of doing it ourselves.
+ * If we ever need to do something fancier than what objcopy provides,
+ * it would be straightforward to add here.
+ *
+ * We keep a section table for a few reasons:
+ *
+ * Binutils has issues debugging the vDSO: it reads the section table to
+ * find SHT_NOTE; it won't look at PT_NOTE for the in-memory vDSO, which
+ * would break build-id if we removed the section table. Binutils
+ * also requires that shstrndx != 0. See:
+ * https://sourceware.org/bugzilla/show_bug.cgi?id=17064
+ *
+ * elfutils might not look for PT_NOTE if there is a section table at
+ * all. I don't know whether this matters for any practical purpose.
+ *
+ * For simplicity, rather than hacking up a partial section table, we
+ * just write a mostly complete one. We omit non-dynamic symbols,
+ * though, since they're rather large.
+ *
+ * Once binutils gets fixed, we might be able to drop this for all but
+ * the 64-bit vdso, since build-id only works in kernel RPMs, and
+ * systems that update to new enough kernel RPMs will likely update
+ * binutils in sync. build-id has never worked for home-built kernel
+ * RPMs without manual symlinking, and I suspect that no one ever does
+ * that.

+/** DOC: Emulation for User-Mode Instruction Prevention (UMIP)
+ *
+ * The feature User-Mode Instruction Prevention present in recent Intel
+ * processor prevents a group of instructions (sgdt, sidt, sldt, smsw, and str)
+ * from being executed with CPL > 0. Otherwise, a general protection fault is
+ * issued.
+ *
+ * Rather than relaying to the user space the general protection fault caused by
+ * the UMIP-protected instructions (in the form of a SIGSEGV signal), it can be
+ * trapped and emulate the result of such instructions to provide dummy values.
+ * This allows to both conserve the current kernel behavior and not reveal the
+ * system resources that UMIP intends to protect (i.e., the locations of the
+ * global descriptor and interrupt descriptor tables, the segment selectors of
+ * the local descriptor table, the value of the task state register and the
+ * contents of the CR0 register).
+ *
+ * This emulation is needed because certain applications (e.g., WineHQ and
+ * DOSEMU2) rely on this subset of instructions to function.
+ *
+ * The instructions protected by UMIP can be split in two groups. Those which
+ * return a kernel memory address (sgdt and sidt) and those which return a
+ * value (sldt, str and smsw).
+ *
+ * For the instructions that return a kernel memory address, applications
+ * such as WineHQ rely on the result being located in the kernel memory space,
+ * not the actual location of the table. The result is emulated as a hard-coded
+ * value that, lies close to the top of the kernel memory. The limit for the GDT
+ * and the IDT are set to zero.
+ *
+ * Given that sldt and str are not commonly used in programs that run on WineHQ
+ * or DOSEMU2, they are not emulated.
+ *
+ * The instruction smsw is emulated to return the value that the register CR0
+ * has at boot time as set in the head_32.
+ *
+ * Also, emulation is provided only for 32-bit processes; 64-bit processes
+ * that attempt to use the instructions that UMIP protects will receive the
+ * SIGSEGV signal issued as a consequence of the general protection fault.
+ *
+ * Care is taken to appropriately emulate the results when segmentation is
+ * used. That is, rather than relying on USER_DS and USER_CS, the function
+ * insn_get_addr_ref() inspects the segment descriptor pointed by the
+ * registers in pt_regs. This ensures that we correctly obtain the segment
+ * base address and the address and operand sizes even if the user space
+ * application uses a local descriptor table.
