+Description:	POWERNV CPUFreq driver's frequency throttle stats directory and

+
+		'cpuX/cpufreq/throttle_stats' directory contains the CPU frequency
+		throttle stat attributes for the chip. The throttle stats of a cpu
+		is common across all the cpus belonging to a chip. Below are the
+		throttle attributes exported in the 'throttle_stats' directory:
+
+		- turbo_stat : This file gives the total number of times the max
+		frequency is throttled to lower frequency in turbo (at and above
+		nominal frequency) range of frequencies.
+
+		- sub_turbo_stat : This file gives the total number of times the
+		max frequency is throttled to lower frequency in sub-turbo(below
+		nominal frequency) range of frequencies.
+
+		- unthrottle : This file gives the total number of times the max
+		frequency is unthrottled after being throttled.
+
+		- powercap : This file gives the total number of times the max
+		frequency is throttled due to 'Power Capping'.
+
+		- overtemp : This file gives the total number of times the max
+		frequency is throttled due to 'CPU Over Temperature'.
+
+		- supply_fault : This file gives the total number of times the
+		max frequency is throttled due to 'Power Supply Failure'.
+
+		- overcurrent : This file gives the total number of times the
+		max frequency is throttled due to 'Overcurrent'.
+
+		- occ_reset : This file gives the total number of times the max
+		frequency is throttled due to 'OCC Reset'.
+
+		The sysfs attributes representing different throttle reasons like

+Date:		August 2015
+Contact:	Gabriel Somlo <somlo@cmu.edu>
+Description:
+		Several different architectures supported by QEMU (x86, arm,
+		sun4*, ppc/mac) are provisioned with a firmware configuration
+		(fw_cfg) device, originally intended as a way for the host to
+		provide configuration data to the guest firmware. Starting
+		with QEMU v2.4, arbitrary fw_cfg file entries may be specified
+		by the user on the command line, which makes fw_cfg additionally
+		useful as an out-of-band, asynchronous mechanism for providing
+		configuration data to the guest userspace.
+
+		The authoritative guest-side hardware interface documentation
+		to the fw_cfg device can be found in "docs/specs/fw_cfg.txt"
+		in the QEMU source tree.
+
+		=== SysFS fw_cfg Interface ===
+
+		The fw_cfg sysfs interface described in this document is only
+		intended to display discoverable blobs (i.e., those registered
+		with the file directory), as there is no way to determine the
+		presence or size of "legacy" blobs (with selector keys between
+		0x0002 and 0x0018) programmatically.
+
+		All fw_cfg information is shown under:
+
+			/sys/firmware/qemu_fw_cfg/
+
+		The only legacy blob displayed is the fw_cfg device revision:
+
+			/sys/firmware/qemu_fw_cfg/rev
+
+		--- Discoverable fw_cfg blobs by selector key ---
+
+		All discoverable blobs listed in the fw_cfg file directory are
+		displayed as entries named after their unique selector key
+		value, e.g.:
+
+			/sys/firmware/qemu_fw_cfg/by_key/32
+			/sys/firmware/qemu_fw_cfg/by_key/33
+			/sys/firmware/qemu_fw_cfg/by_key/34
+			...
+
+		Each such fw_cfg sysfs entry has the following values exported
+		as attributes:
+
+		name  	: The 56-byte nul-terminated ASCII string used as the
+			  blob's 'file name' in the fw_cfg directory.
+		size  	: The length of the blob, as given in the fw_cfg
+			  directory.
+		key	: The value of the blob's selector key as given in the
+			  fw_cfg directory. This value is the same as used in
+			  the parent directory name.
+		raw	: The raw bytes of the blob, obtained by selecting the
+			  entry via the control register, and reading a number
+			  of bytes equal to the blob size from the data
+			  register.
+
+		--- Listing fw_cfg blobs by file name ---
+
+		While the fw_cfg device does not impose any specific naming
+		convention on the blobs registered in the file directory,
+		QEMU developers have traditionally used path name semantics
+		to give each blob a descriptive name. For example:
+
+			"bootorder"
+			"genroms/kvmvapic.bin"
+			"etc/e820"
+			"etc/boot-fail-wait"
+			"etc/system-states"
+			"etc/table-loader"
+			"etc/acpi/rsdp"
+			"etc/acpi/tables"
+			"etc/smbios/smbios-tables"
+			"etc/smbios/smbios-anchor"
+			...
+
+		In addition to the listing by unique selector key described
+		above, the fw_cfg sysfs driver also attempts to build a tree
+		of directories matching the path name components of fw_cfg
+		blob names, ending in symlinks to the by_key entry for each
+		"basename", as illustrated below (assume current directory is
+		/sys/firmware):
+
+		    qemu_fw_cfg/by_name/bootorder -> ../by_key/38
+		    qemu_fw_cfg/by_name/etc/e820 -> ../../by_key/35
+		    qemu_fw_cfg/by_name/etc/acpi/rsdp -> ../../../by_key/41
+		    ...
+
+		Construction of the directory tree and symlinks is done on a
+		"best-effort" basis, as there is no guarantee that components
+		of fw_cfg blob names are always "well behaved". I.e., there is
+		the possibility that a symlink (basename) will conflict with
+		a dirname component of another fw_cfg blob, in which case the
+		creation of the offending /sys/firmware/qemu_fw_cfg/by_name
+		entry will be skipped.
+
+		The authoritative list of entries will continue to be found
+		under the /sys/firmware/qemu_fw_cfg/by_key directory.

+DMA_ATTR_ALLOC_SINGLE_PAGES
+---------------------------
+
+This is a hint to the DMA-mapping subsystem that it's probably not worth
+the time to try to allocate memory to in a way that gives better TLB
+efficiency (AKA it's not worth trying to build the mapping out of larger
+pages).  You might want to specify this if:
+- You know that the accesses to this memory won't thrash the TLB.
+  You might know that the accesses are likely to be sequential or
+  that they aren't sequential but it's unlikely you'll ping-pong
+  between many addresses that are likely to be in different physical
+  pages.
+- You know that the penalty of TLB misses while accessing the
+  memory will be small enough to be inconsequential.  If you are
+  doing a heavy operation like decryption or decompression this
+  might be the case.
+- You know that the DMA mapping is fairly transitory.  If you expect
+  the mapping to have a short lifetime then it may be worth it to
+  optimize allocation (avoid coming up with large pages) instead of
+  getting the slight performance win of larger pages.
+Setting this hint doesn't guarantee that you won't get huge pages, but it
+means that we won't try quite as hard to get them.
+
+NOTE: At the moment DMA_ATTR_ALLOC_SINGLE_PAGES is only implemented on ARM,
+though ARM64 patches will likely be posted soon.

-This driver is for Compaq's SMART2 Intelligent Disk Array Controllers.
-
-Supported Cards:
-----------------
-
-This driver is known to work with the following cards:
-
-	* SMART (EISA)
-	* SMART-2/E (EISA)
-	* SMART-2/P
-	* SMART-2DH
-	* SMART-2SL
-	* SMART-221
-	* SMART-3100ES
-	* SMART-3200
-	* Integrated Smart Array Controller
-	* SA 4200
-	* SA 4250ES
-	* SA 431
-	* RAID LC2 Controller
-
-It should also work with some really old Disk array adapters, but I am
-unable to test against these cards:
-
-	* IDA
-	* IDA-2
-	* IAES
-
-
-EISA Controllers:
------------------
-
-If you want to use an EISA controller you'll have to supply some
-modprobe/lilo parameters.  If the driver is compiled into the kernel, must
-give it the controller's IO port address at boot time (it is not
-necessary to specify the IRQ).  For example, if you had two SMART-2/E
-controllers, in EISA slots 1 and 2 you'd give it a boot argument like
-this:
-
-	smart2=0x1000,0x2000
-
-If you were loading the driver as a module, you'd give load it like this:
-
-	modprobe cpqarray eisa=0x1000,0x2000
-
-You can use EISA and PCI adapters at the same time.
-
-
-Device Naming:
---------------
-
-You need some entries in /dev for the ida device.  MAKEDEV in the /dev
-directory can make device nodes for you automatically.  The device setup is
-as follows:

+6. Namespace
+
+6-1. Basics
+
+cgroup namespace provides a mechanism to virtualize the view of the
+"/proc/$PID/cgroup" file and cgroup mounts.  The CLONE_NEWCGROUP clone
+flag can be used with clone(2) and unshare(2) to create a new cgroup
+namespace.  The process running inside the cgroup namespace will have
+its "/proc/$PID/cgroup" output restricted to cgroupns root.  The
+cgroupns root is the cgroup of the process at the time of creation of
+the cgroup namespace.
+
+Without cgroup namespace, the "/proc/$PID/cgroup" file shows the
+complete path of the cgroup of a process.  In a container setup where
+a set of cgroups and namespaces are intended to isolate processes the
+"/proc/$PID/cgroup" file may leak potential system level information
+to the isolated processes.  For Example:
+
+  # cat /proc/self/cgroup
+  0::/batchjobs/container_id1
+
+The path '/batchjobs/container_id1' can be considered as system-data
+and undesirable to expose to the isolated processes.  cgroup namespace
+can be used to restrict visibility of this path.  For example, before
+creating a cgroup namespace, one would see:
+
+  # ls -l /proc/self/ns/cgroup
+  lrwxrwxrwx 1 root root 0 2014-07-15 10:37 /proc/self/ns/cgroup -> cgroup:[4026531835]
+  # cat /proc/self/cgroup
+  0::/batchjobs/container_id1
+
+After unsharing a new namespace, the view changes.
+
+  # ls -l /proc/self/ns/cgroup
+  lrwxrwxrwx 1 root root 0 2014-07-15 10:35 /proc/self/ns/cgroup -> cgroup:[4026532183]
+  # cat /proc/self/cgroup
+  0::/
+
+When some thread from a multi-threaded process unshares its cgroup
+namespace, the new cgroupns gets applied to the entire process (all
+the threads).  This is natural for the v2 hierarchy; however, for the
+legacy hierarchies, this may be unexpected.
+
+A cgroup namespace is alive as long as there are processes inside or
+mounts pinning it.  When the last usage goes away, the cgroup
+namespace is destroyed.  The cgroupns root and the actual cgroups
+remain.
+
+
+6-2. The Root and Views
+
+The 'cgroupns root' for a cgroup namespace is the cgroup in which the
+process calling unshare(2) is running.  For example, if a process in
+/batchjobs/container_id1 cgroup calls unshare, cgroup
+/batchjobs/container_id1 becomes the cgroupns root.  For the
+init_cgroup_ns, this is the real root ('/') cgroup.
+
+The cgroupns root cgroup does not change even if the namespace creator
+process later moves to a different cgroup.
+
+  # ~/unshare -c # unshare cgroupns in some cgroup
+  # cat /proc/self/cgroup
+  0::/
+  # mkdir sub_cgrp_1
+  # echo 0 > sub_cgrp_1/cgroup.procs
+  # cat /proc/self/cgroup
+  0::/sub_cgrp_1
+
+Each process gets its namespace-specific view of "/proc/$PID/cgroup"
+
+Processes running inside the cgroup namespace will be able to see
+cgroup paths (in /proc/self/cgroup) only inside their root cgroup.
+From within an unshared cgroupns:
+
+  # sleep 100000 &
+  [1] 7353
+  # echo 7353 > sub_cgrp_1/cgroup.procs
+  # cat /proc/7353/cgroup
+  0::/sub_cgrp_1
+
+From the initial cgroup namespace, the real cgroup path will be
+visible:
+
+  $ cat /proc/7353/cgroup
+  0::/batchjobs/container_id1/sub_cgrp_1
+
+From a sibling cgroup namespace (that is, a namespace rooted at a
+different cgroup), the cgroup path relative to its own cgroup
+namespace root will be shown.  For instance, if PID 7353's cgroup
+namespace root is at '/batchjobs/container_id2', then it will see
+
+  # cat /proc/7353/cgroup
+  0::/../container_id2/sub_cgrp_1
+
+Note that the relative path always starts with '/' to indicate that
+its relative to the cgroup namespace root of the caller.
+
+
+6-3. Migration and setns(2)
+
+Processes inside a cgroup namespace can move into and out of the
+namespace root if they have proper access to external cgroups.  For
+example, from inside a namespace with cgroupns root at
+/batchjobs/container_id1, and assuming that the global hierarchy is
+still accessible inside cgroupns:
+
+  # cat /proc/7353/cgroup
+  0::/sub_cgrp_1
+  # echo 7353 > batchjobs/container_id2/cgroup.procs
+  # cat /proc/7353/cgroup
+  0::/../container_id2
+
+Note that this kind of setup is not encouraged.  A task inside cgroup
+namespace should only be exposed to its own cgroupns hierarchy.
+
+setns(2) to another cgroup namespace is allowed when:
+
+(a) the process has CAP_SYS_ADMIN against its current user namespace
+(b) the process has CAP_SYS_ADMIN against the target cgroup
+    namespace's userns
+
+No implicit cgroup changes happen with attaching to another cgroup
+namespace.  It is expected that the someone moves the attaching
+process under the target cgroup namespace root.
+
+
+6-4. Interaction with Other Namespaces
+
+Namespace specific cgroup hierarchy can be mounted by a process
+running inside a non-init cgroup namespace.
+
+  # mount -t cgroup2 none $MOUNT_POINT
+
+This will mount the unified cgroup hierarchy with cgroupns root as the
+filesystem root.  The process needs CAP_SYS_ADMIN against its user and
+mount namespaces.
+
+The virtualization of /proc/self/cgroup file combined with restricting
+the view of cgroup hierarchy by namespace-private cgroupfs mount
+provides a properly isolated cgroup view inside the container.

 multiqueue (mq)
 ---------------
 
-This policy has been deprecated in favor of the smq policy (see below).
+This policy is now an alias for smq (see below).
 
-The multiqueue policy has three sets of 16 queues: one set for entries
-waiting for the cache and another two for those in the cache (a set for
-clean entries and a set for dirty entries).
+The following tunables are accepted, but have no effect:
 
-Cache entries in the queues are aged based on logical time. Entry into
-the cache is based on variable thresholds and queue selection is based
-on hit count on entry. The policy aims to take different cache miss
-costs into account and to adjust to varying load patterns automatically.
-
-Message and constructor argument pairs are:
 	'sequential_threshold <#nr_sequential_ios>'
 	'random_threshold <#nr_random_ios>'
 	'read_promote_adjustment <value>'
 	'write_promote_adjustment <value>'
 	'discard_promote_adjustment <value>'
 
-The sequential threshold indicates the number of contiguous I/Os
-required before a stream is treated as sequential.  Once a stream is
-considered sequential it will bypass the cache.  The random threshold
-is the number of intervening non-contiguous I/Os that must be seen
-before the stream is treated as random again.
-
-The sequential and random thresholds default to 512 and 4 respectively.
-
-Large, sequential I/Os are probably better left on the origin device
-since spindles tend to have good sequential I/O bandwidth.  The
-io_tracker counts contiguous I/Os to try to spot when the I/O is in one
-of these sequential modes.  But there are use-cases for wanting to
-promote sequential blocks to the cache (e.g. fast application startup).
-If sequential threshold is set to 0 the sequential I/O detection is
-disabled and sequential I/O will no longer implicitly bypass the cache.
-Setting the random threshold to 0 does _not_ disable the random I/O
-stream detection.
-
-Internally the mq policy determines a promotion threshold.  If the hit
-count of a block not in the cache goes above this threshold it gets
-promoted to the cache.  The read, write and discard promote adjustment
-tunables allow you to tweak the promotion threshold by adding a small
-value based on the io type.  They default to 4, 8 and 1 respectively.
-If you're trying to quickly warm a new cache device you may wish to
-reduce these to encourage promotion.  Remember to switch them back to
-their defaults after the cache fills though.

 registers; their location is communicated to the guest's UEFI firmware in the
 DTB that QEMU places at the bottom of the guest's DRAM.
 
-The guest writes a selector value (a key) to the selector register, and then
-can read the corresponding data (produced by QEMU) via the data register. If
-the selected entry is writable, the guest can rewrite it through the data
-register.
+The authoritative guest-side hardware interface documentation to the fw_cfg
+device can be found in "docs/specs/fw_cfg.txt" in the QEMU source tree.
 
-The selector register takes keys in big endian byte order.
-
-The data register allows accesses with 8, 16, 32 and 64-bit width (only at
-offset 0 of the register). Accesses larger than a byte are interpreted as
-arrays, bundled together only for better performance. The bytes constituting
-such a word, in increasing address order, correspond to the bytes that would
-have been transferred by byte-wide accesses in chronological order.
-
-The interface allows guest firmware to download various parameters and blobs
-that affect how the firmware works and what tables it installs for the guest
-OS. For example, boot order of devices, ACPI tables, SMBIOS tables, kernel and
-initrd images for direct kernel booting, virtual machine UUID, SMP information,
-virtual NUMA topology, and so on.
-
-The authoritative registry of the valid selector values and their meanings is
-the QEMU source code; the structure of the data blobs corresponding to the
-individual key values is also defined in the QEMU source code.
-
-The presence of the registers can be verified by selecting the "signature" blob
-with key 0x0000, and reading four bytes from the data register. The returned
-signature is "QEMU".
-
-The outermost protocol (involving the write / read sequences of the control and
-data registers) is expected to be versioned, and/or described by feature bits.
-The interface revision / feature bitmap can be retrieved with key 0x0001. The
-blob to be read from the data register has size 4, and it is to be interpreted
-as a uint32_t value in little endian byte order. The current value
-(corresponding to the above outer protocol) is zero.
-
-The guest kernel is not expected to use these registers (although it is
-certainly allowed to); the device tree bindings are documented here because
-this is where device tree bindings reside in general.

+QCOM device tree bindings
+-------------------------
+
+Some qcom based bootloaders identify the dtb blob based on a set of
+device properties like SoC and platform and revisions of those components.
+To support this scheme, we encode this information into the board compatible
+string.
+
+Each board must specify a top-level board compatible string with the following
+format:
+
+	compatible = "qcom,<SoC>[-<soc_version>][-<foundry_id>]-<board>[/<subtype>][-<board_version>]"
+
+The 'SoC' and 'board' elements are required. All other elements are optional.
+
+The 'SoC' element must be one of the following strings:
+
+	apq8016
+	apq8074
+	apq8084
+	apq8096
+	msm8916
+	msm8974
+	msm8996
+
+The 'board' element must be one of the following strings:
+
+	cdp
+	liquid
+	dragonboard
+	mtp
+	sbc
+
+The 'soc_version' and 'board_version' elements take the form of v<Major>.<Minor>
+where the minor number may be omitted when it's zero, i.e.  v1.0 is the same
+as v1. If all versions of the 'board_version' elements match, then a
+wildcard '*' should be used, e.g. 'v*'.
+
+The 'foundry_id' and 'subtype' elements are one or more digits from 0 to 9.
+
+Examples:
+
+	"qcom,msm8916-v1-cdp-pm8916-v2.1"
+
+A CDP board with an msm8916 SoC, version 1 paired with a pm8916 PMIC of version
+2.1.
+
+	"qcom,apq8074-v2.0-2-dragonboard/1-v0.1"
+
+A dragonboard board v0.1 of subtype 1 with an apq8074 SoC version 2, made in

+* NXP LPC1850 CREG clocks
+
+The NXP LPC18xx/43xx CREG (Configuration Registers) block contains
+control registers for two low speed clocks. One of the clocks is a
+32 kHz oscillator driver with power up/down and clock gating. Next
+is a fixed divider that creates a 1 kHz clock from the 32 kHz osc.
+
+These clocks are used by the RTC and the Event Router peripherials.
+The 32 kHz can also be routed to other peripherials to enable low
+power modes.
+
+This binding uses the common clock binding:
+    Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible:
+	Should be "nxp,lpc1850-creg-clk"
+- #clock-cells:
+	Shall have value <1>.
+- clocks:
+	Shall contain a phandle to the fixed 32 kHz crystal.
+
+The creg-clk node must be a child of the creg syscon node.
+
+The following clocks are available from the clock node.
+
+Clock ID	Name
+   0		 1 kHz clock
+   1		32 kHz Oscillator

+ARM HDLCD
+
+This is a display controller found on several development platforms produced
+by ARM Ltd and in more modern of its' Fast Models. The HDLCD is an RGB
+streamer that reads the data from a framebuffer and sends it to a single
+digital encoder (DVI or HDMI).
+
+Required properties:
+  - compatible: "arm,hdlcd"
+  - reg: Physical base address and length of the controller's registers.
+  - interrupts: One interrupt used by the display controller to notify the
+    interrupt controller when any of the interrupt sources programmed in
+    the interrupt mask register have activated.
+  - clocks: A list of phandle + clock-specifier pairs, one for each
+    entry in 'clock-names'.
+  - clock-names: A list of clock names. For HDLCD it should contain:
+      - "pxlclk" for the clock feeding the output PLL of the controller.
+
+Required sub-nodes:
+  - port: The HDLCD connection to an encoder chip. The connection is modeled
+    using the OF graph bindings specified in
+    Documentation/devicetree/bindings/graph.txt.
+
+Optional properties:
+  - memory-region: phandle to a node describing memory (see
+    Documentation/devicetree/bindings/reserved-memory/reserved-memory.txt) to be
+    used for the framebuffer; if not present, the framebuffer may be located
+    anywhere in memory.
+
+
+Example:
+

+Qualcomm Technologies HIDMA Management interface
+
+Qualcomm Technologies HIDMA is a high speed DMA device. It only supports
+memcpy and memset capabilities. It has been designed for virtualized
+environments.
+
+Each HIDMA HW instance consists of multiple DMA channels. These channels
+share the same bandwidth. The bandwidth utilization can be parititioned
+among channels based on the priority and weight assignments.
+
+There are only two priority levels and 15 weigh assignments possible.
+
+Other parameters here determine how much of the system bus this HIDMA
+instance can use like maximum read/write request and and number of bytes to
+read/write in a single burst.
+
+Main node required properties:
+- compatible: "qcom,hidma-mgmt-1.0";
+- reg: Address range for DMA device
+- dma-channels: Number of channels supported by this DMA controller.
+- max-write-burst-bytes: Maximum write burst in bytes that HIDMA can
+  occupy the bus for in a single transaction. A memcpy requested is
+  fragmented to multiples of this amount. This parameter is used while
+  writing into destination memory. Setting this value incorrectly can
+  starve other peripherals in the system.
+- max-read-burst-bytes: Maximum read burst in bytes that HIDMA can
+  occupy the bus for in a single transaction. A memcpy request is
+  fragmented to multiples of this amount. This parameter is used while
+  reading the source memory. Setting this value incorrectly can starve
+  other peripherals in the system.
+- max-write-transactions: This value is how many times a write burst is
+  applied back to back while writing to the destination before yielding
+  the bus.
+- max-read-transactions: This value is how many times a read burst is
+  applied back to back while reading the source before yielding the bus.
+- channel-reset-timeout-cycles: Channel reset timeout in cycles for this SOC.
+  Once a reset is applied to the HW, HW starts a timer for reset operation
+  to confirm. If reset is not completed within this time, HW reports reset
+  failure.
+
+Sub-nodes:
+
+HIDMA has one or more DMA channels that are used to move data from one
+memory location to another.
+
+When the OS is not in control of the management interface (i.e. it's a guest),
+the channel nodes appear on their own, not under a management node.
+
+Required properties:
+- compatible: must contain "qcom,hidma-1.0"
+- reg: Addresses for the transfer and event channel
+- interrupts: Should contain the event interrupt
+- desc-count: Number of asynchronous requests this channel can handle
+- iommus: required a iommu node

+Pinctrl-based I2C Bus DeMux
+
+This binding describes an I2C bus demultiplexer that uses pin multiplexing to
+route the I2C signals, and represents the pin multiplexing configuration using
+the pinctrl device tree bindings. This may be used to select one I2C IP core at
+runtime which may have a better feature set for a given task than another I2C
+IP core on the SoC. The most simple example is to fall back to GPIO bitbanging
+if your current runtime configuration hits an errata of the internal IP core.

+- i2c-parent: List of phandles of I2C masters available for selection. The first
+	      one will be used as default.
+- i2c-bus-name: The name of this bus. Also needed as pinctrl-name for the I2C
+		parents.
+
+Furthermore, I2C mux properties and child nodes. See mux.txt in this directory.
+
+Example:
+
+Here is a snipplet for a bus to be demuxed. It contains various i2c clients for
+HDMI, so the bus is named "i2c-hdmi":
+
+	i2chdmi: i2c@8 {
+
+		compatible = "i2c-demux-pinctrl";
+		i2c-parent = <&gpioi2c>, <&iic2>, <&i2c2>;
+		i2c-bus-name = "i2c-hdmi";
+		#address-cells = <1>;
+		#size-cells = <0>;
+
+		ak4643: sound-codec@12 {
+			compatible = "asahi-kasei,ak4643";
+
+			#sound-dai-cells = <0>;
+			reg = <0x12>;
+		};
+
+		composite-in@20 {
+			compatible = "adi,adv7180";
+			reg = <0x20>;
+			remote = <&vin1>;
+
+			port {
+				adv7180: endpoint {
+					bus-width = <8>;
+					remote-endpoint = <&vin1ep0>;
+				};
+			};
+		};
+
+		hdmi@39 {
+			compatible = "adi,adv7511w";
+			reg = <0x39>;
+			interrupt-parent = <&gpio1>;
+			interrupts = <15 IRQ_TYPE_LEVEL_LOW>;
+
+			adi,input-depth = <8>;
+			adi,input-colorspace = "rgb";
+			adi,input-clock = "1x";
+			adi,input-style = <1>;
+			adi,input-justification = "evenly";
+
+			ports {
+				#address-cells = <1>;
+				#size-cells = <0>;
+
+				port@0 {
+					reg = <0>;
+					adv7511_in: endpoint {
+						remote-endpoint = <&du_out_lvds0>;
+					};
+				};
+
+				port@1 {
+					reg = <1>;
+					adv7511_out: endpoint {
+						remote-endpoint = <&hdmi_con>;
+					};
+				};
+			};
+		};
+	};
+
+And for clarification, here are the snipplets for the i2c-parents:
+
+	gpioi2c: i2c@9 {
+		#address-cells = <1>;
+		#size-cells = <0>;
+		compatible = "i2c-gpio";
+		status = "disabled";
+		gpios = <&gpio5 6 GPIO_ACTIVE_HIGH /* sda */

+&iic2	{
+	pinctrl-0 = <&iic2_pins>;
+	pinctrl-names = "i2c-hdmi";
+
+	clock-frequency = <100000>;
+};
+
+Please note:
+
+- pinctrl properties for the parent I2C controllers need a pinctrl state
+  with the same name as i2c-bus-name, not "default"!
+
+- the i2c masters must have their status "disabled". This driver will
+  enable them at runtime when needed.

+ - fsl,pen-debounce-ns: Pen debounce time in nanoseconds.
+ - fsl,pen-threshold: Pen-down threshold for the touchscreen. This is a value
+   between 1 and 4096. It is the ratio between the internal reference voltage
+   and the measured voltage after the plate was precharged. Resistence between
+   plates and therefore the voltage decreases with pressure so that a smaller
+   value is equivalent to a higher pressure.
+ - fsl,settling-time-ns: Settling time in nanoseconds. The settling time is before
+   the actual touch detection to wait for an even charge distribution in the
+   plate.
+
+This device includes two conversion queues which can be added as subnodes.
+The first queue is for the touchscreen, the second for general purpose ADC.

+Hisilicon Hi6220 Mailbox Driver
+===============================
+
+Hisilicon Hi6220 mailbox supports up to 32 channels. Each channel
+is unidirectional with a maximum message size of 8 words. I/O is
+performed using register access (there is no DMA) and the cell
+raises an interrupt when messages are received.
+
+Mailbox Device Node:
+====================
+
+Required properties:
+--------------------
+- compatible:		Shall be "hisilicon,hi6220-mbox"
+- reg:			Contains the mailbox register address range (base
+			address and length); the first item is for IPC
+			registers, the second item is shared buffer for
+			slots.
+- #mbox-cells:		Common mailbox binding property to identify the number
+			of cells required for the mailbox specifier. Must be 3.
+			<&phandle slot_id dst_irq ack_irq>
+			  phandle: Label name of mailbox controller
+			  slot_id: Slot id used either for TX or RX
+			  dst_irq: IRQ identifier index number which used by MCU
+			  ack_irq: IRQ identifier index number with generating a
+			           TX/RX interrupt to application processor,
+				   mailbox driver uses it to acknowledge interrupt
+- interrupts:		Contains the interrupt information for the mailbox
+			device. The format is dependent on which interrupt
+			controller the SoCs use.
+
+Optional Properties:
+--------------------
+- hi6220,mbox-tx-noirq: Property of MCU firmware's feature, so mailbox driver
+			use this flag to ask MCU to enable "automatic idle
+			flag" mode or IRQ generated mode to acknowledge a TX
+			completion.
+
+Example:
+--------
+
+	mailbox: mailbox@f7510000 {
+		compatible = "hisilicon,hi6220-mbox";
+		reg = <0x0 0xf7510000 0x0 0x1000>, /* IPC_S */

+
+PIC32 'pin configuration node' is a node of a group of pins which can be
+used for a specific device or function. This node represents configuraions of
+pins, optional function, and optional mux related configuration.
+
+Required properties for pin controller node:
+ - compatible: "microchip,pic32mada-pinctrl"
+ - reg: Address range of the pinctrl registers.
+ - clocks: Clock specifier (see clock bindings for details)
+
+Required properties for pin configuration sub-nodes:
+ - pins: List of pins to which the configuration applies.
+
+Optional properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - function: Mux function for the specified pins.
+ - bias-pull-up: Enable weak pull-up.
+ - bias-pull-down: Enable weak pull-down.
+ - input-enable: Set the pin as an input.
+ - output-low: Set the pin as an output level low.
+ - output-high: Set the pin as an output level high.
+ - microchip,digital: Enable digital I/O.
+ - microchip,analog: Enable analog I/O.

+Qualcomm Atheros IPQ4019 TLMM block
+
+This is the Top Level Mode Multiplexor block found on the Qualcomm IPQ8019
+platform, it provides pinctrl, pinmux, pinconf, and gpiolib facilities.
+
+Required properties:
+- compatible: "qcom,ipq4019-pinctrl"
+- reg: Should be the base address and length of the TLMM block.
+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+                The first cell is the gpio pin number and the
+                second cell is used for optional parameters.
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+ pins, function, bias-disable, bias-pull-down, bias-pull,up, drive-strength.
+
+Non-empty subnodes must specify the 'pins' property.
+Note that not all properties are valid for all pins.
+
+
+Valid values for qcom,pins are:
+  gpio0-gpio99
+    Supports mux, bias and drive-strength
+
+Valid values for qcom,function are:
+gpio, blsp_uart1, blsp_i2c0, blsp_i2c1, blsp_uart0, blsp_spi1, blsp_spi0

+Details of regulator properties are defined as child node under
+sub-node "regulators" which is child node of device node.
+
+Please refer file <Documentation/devicetree/bindings/regulator/regulator.txt>
+for common regulator bindings used by client.
+

+Optional properties:
+-------------------
+The input supply of regulators are the optional properties on the
+parent device node. The input supply of these regulators are provided
+through following properties:
+in-sd0-supply:		Input supply for SD0, INA-SD0 or INB-SD0 pins.

+Optional sub nodes for regulators under "regulators" subnode:
+------------------------------------------------------------
+The subnodes name is the name of regulator and it must be one of:
+	sd[0-3], ldo[0-8]
+
+Each sub-node should contain the constraints and initialization
+information for that regulator. The definition for each of these
+nodes is defined using the standard binding for regulators found at
+<Documentation/devicetree/bindings/regulator/regulator.txt>.
+
+Theres are also additional properties for SD/LDOs. These additional properties
+are required to configure FPS configuration parameters for SDs and LDOs.
+Please refer <devicetree/bindings/mfd/max77620.txt> for more detail of Flexible
+Power Sequence (FPS).
+Following are additional properties:
+
+- maxim,active-fps-source:		FPS source for the regulators to get
+					enabled/disabled when system is in
+					active state.  Valid values are:
+					- MAX77620_FPS_SRC_0,
+						FPS source is FPS0.
+					- MAX77620_FPS_SRC_1,
+						FPS source is FPS1
+					- MAX77620_FPS_SRC_2 and
+						FPS source is FPS2
+					- MAX77620_FPS_SRC_NONE.
+						Regulator is not controlled
+						by FPS events and it gets
+						enabled/disabled by register
+						access.
+					Absence of this property will leave
+					the FPS configuration register for that
+					regulator to default configuration.
+
+- maxim,active-fps-power-up-slot:	Sequencing event slot number on which
+					the regulator get enabled when
+					master FPS input event set to HIGH.
+					Valid values are 0 to 7.
+					This is applicable if FPS source is
+					selected as FPS0, FPS1 or FPS2.
+			
+- maxim,active-fps-power-down-slot:	Sequencing event slot number on which
+					the regulator get disabled when master
+					FPS input event set to LOW.
+					Valid values are 0 to 7.
+					This is applicable if FPS source is
+					selected as FPS0, FPS1 or FPS2.
+			
+- maxim,suspend-fps-source:		This is same as property
+					"maxim,active-fps-source" but value
+					get configured when system enters in
+					to suspend state.
+
+- maxim,suspend-fps-power-up-slot:	This is same as property
+					"maxim,active-fps-power-up-slot" but

+Pistachio Reset Controller
+=============================================================================
+
+This binding describes a reset controller device that is used to enable and
+disable individual IP blocks within the Pistachio SoC using "soft reset"
+control bits found in the Pistachio SoC top level registers.
+
+The actual action taken when soft reset is asserted is hardware dependent.
+However, when asserted it may not be possible to access the hardware's
+registers, and following an assert/deassert sequence the hardware's previous
+state may no longer be valid.
+
+Please refer to Documentation/devicetree/bindings/reset/reset.txt
+for common reset controller binding usage.
+
+Required properties:
+
+- compatible: Contains "img,pistachio-reset"
+
+- #reset-cells: Contains 1
+
+Example:
+
+	cr_periph: clk@18148000 {
+		compatible = "img,pistachio-cr-periph", "syscon", "simple-mfd";
+		reg = <0x18148000 0x1000>;
+		clocks = <&clk_periph PERIPH_CLK_SYS>;
+		clock-names = "sys";
+		#clock-cells = <1>;
+
+		pistachio_reset: reset-controller {
+			compatible = "img,pistachio-reset";
+			#reset-cells = <1>;
+		};
+	};
+
+Specifying reset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the pistachio reset device node and an
+index specifying which reset to use, as described in
+Documentation/devicetree/bindings/reset/reset.txt.
+
+Example:
+
+	spdif_out: spdif-out@18100d00 {

+* Run Control and Power Management
+-------------------------------------------
+The RCPM performs all device-level tasks associated with device run control
+and power management.
+
+Required properites:
+  - reg : Offset and length of the register set of the RCPM block.
+  - fsl,#rcpm-wakeup-cells : The number of IPPDEXPCR register cells in the
+	fsl,rcpm-wakeup property.
+  - compatible : Must contain a chip-specific RCPM block compatible string
+	and (if applicable) may contain a chassis-version RCPM compatible
+	string. Chip-specific strings are of the form "fsl,<chip>-rcpm",
+	such as:
+	* "fsl,p2041-rcpm"
+	* "fsl,p5020-rcpm"
+	* "fsl,t4240-rcpm"
+
+	Chassis-version strings are of the form "fsl,qoriq-rcpm-<version>",
+	such as:
+	* "fsl,qoriq-rcpm-1.0": for chassis 1.0 rcpm
+	* "fsl,qoriq-rcpm-2.0": for chassis 2.0 rcpm
+	* "fsl,qoriq-rcpm-2.1": for chassis 2.1 rcpm
+
+All references to "1.0" and "2.0" refer to the QorIQ chassis version to
+which the chip complies.
+Chassis Version		Example Chips
+---------------		-------------------------------
+1.0				p4080, p5020, p5040, p2041, p3041
+2.0				t4240, b4860, b4420
+2.1				t1040, ls1021
+
+Example:
+The RCPM node for T4240:
+	rcpm: global-utilities@e2000 {
+		compatible = "fsl,t4240-rcpm", "fsl,qoriq-rcpm-2.0";
+		reg = <0xe2000 0x1000>;
+		fsl,#rcpm-wakeup-cells = <2>;
+	};
+
+* Freescale RCPM Wakeup Source Device Tree Bindings
+-------------------------------------------
+Required fsl,rcpm-wakeup property should be added to a device node if the device
+can be used as a wakeup source.
+
+  - fsl,rcpm-wakeup: Consists of a phandle to the rcpm node and the IPPDEXPCR
+	register cells. The number of IPPDEXPCR register cells is defined in
+	"fsl,#rcpm-wakeup-cells" in the rcpm node. The first register cell is
+	the bit mask that should be set in IPPDEXPCR0, and the second register
+	cell is for IPPDEXPCR1, and so on.
+
+	Note: IPPDEXPCR(IP Powerdown Exception Control Register) provides a
+	mechanism for keeping certain blocks awake during STANDBY and MEM, in
+	order to use them as wake-up sources.
+
+Example:
+	lpuart0: serial@2950000 {

 Renesas R-Car sound
 
+=============================================
+* Modules
+=============================================
+
+Renesas R-Car sound is constructed from below modules
+(for Gen2 or later)
+
+ SCU		: Sampling Rate Converter Unit
+  - SRC		: Sampling Rate Converter
+  - CMD
+   - CTU	: Channel Transfer Unit
+   - MIX	: Mixer
+   - DVC	: Digital Volume and Mute Function
+ SSIU		: Serial Sound Interface Unit
+ SSI		: Serial Sound Interface
+
+See detail of each module's channels, connection, limitation on datasheet
+
+=============================================
+* Multi channel
+=============================================
+
+Multi channel is supported by Multi-SSI, or TDM-SSI.
+
+ Multi-SSI	: 6ch case, you can use stereo x 3 SSI
+ TDM-SSI	: 6ch case, you can use TDM
+
+=============================================
+* Enable/Disable each modules
+=============================================
+
+See datasheet to check SRC/CTU/MIX/DVC connect-limitation.
+DT controls enabling/disabling module.
+${LINUX}/arch/arm/boot/dts/r8a7790-lager.dts can be good example.
+This is example of
+
+Playback: [MEM] -> [SRC2] -> [DVC0] -> [SSIU0/SSI0] -> [codec]
+Capture:  [MEM] <- [DVC1] <- [SRC3] <- [SSIU1/SSI1] <- [codec]

+			dai0 {
+				playback = <&ssi0 &src2 &dvc0>;
+				capture  = <&ssi1 &src3 &dvc1>;
+			};
+		};
+	};
+
+You can use below.

+
+=============================================
+* SRC (Sampling Rate Converter)
+=============================================
+
+ [xx]Hz        [yy]Hz
+ ------> [SRC] ------>
+
+SRC can convert [xx]Hz to [yy]Hz. Then, it has below 2 modes
+
+ Asynchronous mode:	input data / output data are based on different clocks.
+			you can use this mode on Playback / Capture
+ Synchronous mode:	input data / output data are based on same clocks.
+			This mode will be used if system doesn't have its input clock,
+			for example digital TV case.
+			you can use this mode on Playback
+
+------------------
+**     Asynchronous mode
+------------------
+
+You need to use "renesas,rsrc-card" sound card for it.
+example)
+
+	sound {
+		compatible = "renesas,rsrc-card";
+		...

+
+=============================================
+* CTU (Channel Transfer Unit)
+=============================================
+
+ [xx]ch        [yy]ch
+ ------> [CTU] -------->
+
+CTU can convert [xx]ch to [yy]ch, or exchange outputed channel.
+CTU conversion needs matrix settings.

+and these sounds will be merged by MIX.
+
+	aplay -D plughw:0,0 xxxx.wav &

+			};
+		};
+	};
+
+=============================================
+* DVC (Digital Volume and Mute Function)
+=============================================
+
+DVC controls Playback/Capture volume.
+
+Playback Volume
+	amixer set "DVC Out" 100%
+
+Capture Volume
+	amixer set "DVC In" 100%

+	aplay xxx.wav &
+	amixer set "DVC Out"  80%  // Volume Down
+	amixer set "DVC Out" 100%  // Volume Up
+
+=============================================
+* SSIU (Serial Sound Interface Unit)
+=============================================
+
+There is no DT settings for SSIU, because SSIU will be automatically
+selected via SSI.
+SSIU can avoid some under/over run error, because it has some buffer.
+But you can't use it if SSI was PIO mode.
+In DMA mode, you can select not to use SSIU by using "no-busif" on DT.
+
+	&ssi0 {
+		no-busif;
+	};
+
+=============================================
+* SSI (Serial Sound Interface)
+=============================================
+
+**  PIO mode
+
+You can use PIO mode which is for connection check by using.
+Note: The system will drop non-SSI modules in PIO mode
+even though if DT is selecting other modules.
+
+	&ssi0 {
+		pio-transfer
+	};
+
+** DMA mode without SSIU
+
+You can use DMA without SSIU.
+Note: under/over run, or noise are likely to occur
+
+	&ssi0 {
+		no-busif;
+	};
+
+** PIN sharing
+
+Each SSI can share WS pin. It is based on platform.
+This is example if SSI1 want to share WS pin with SSI0
+
+	&ssi1 {
+		shared-pin;
+	};
+
+** Multi-SSI
+
+You can use Multi-SSI.
+This is example of SSI0/SSI1/SSI2 (= for 6ch)
+
+	&rcar_sound {
+		...
+		rcar_sound,dai {
+			dai0 {
+				playback = <&ssi0 &ssi1 &ssi2 &src0 &dvc0>;
+			};
+		};
+	};
+
+** TDM-SSI
+
+You can use TDM with SSI.
+This is example of TDM 6ch.
+Driver can automatically switches TDM <-> stereo mode in this case.
+
+	rsnd_tdm: sound {
+		compatible = "simple-audio-card";

+* Mediatek Thermal
+
+This describes the device tree binding for the Mediatek thermal controller
+which measures the on-SoC temperatures. This device does not have its own ADC,
+instead it directly controls the AUXADC via AHB bus accesses. For this reason
+this device needs phandles to the AUXADC. Also it controls a mux in the
+apmixedsys register space via AHB bus accesses, so a phandle to the APMIXEDSYS
+is also needed.
+

+		       "therm":	 Main clock needed for register access
+		       "auxadc": The AUXADC clock
+- resets: Reference to the reset controller controlling the thermal controller.
+- mediatek,auxadc: A phandle to the AUXADC which the thermal controller uses
+- mediatek,apmixedsys: A phandle to the APMIXEDSYS controller.
+- #thermal-sensor-cells : Should be 0. See ./thermal.txt for a description.

+   used when the access happens. Note that DMA_BUF_IOCTL_SYNC can fail with
+   -EAGAIN or -EINTR, in which case it must be restarted.
+
+   Some systems might need some sort of cache coherency management e.g. when
+   CPU and GPU domains are being accessed through dma-buf at the same time. To
+   circumvent this problem there are begin/end coherency markers, that forward
+   directly to existing dma-buf device drivers vfunc hooks. Userspace can make
+   use of those markers through the DMA_BUF_IOCTL_SYNC ioctl. The sequence
+   would be used like following:
+     - mmap dma-buf fd
+     - for each drawing/upload cycle in CPU 1. SYNC_START ioctl, 2. read/write
+       to mmap area 3. SYNC_END ioctl. This can be repeated as often as you
+       want (with the new data being consumed by the GPU or say scanout device)
+     - munmap once you don't need the buffer any more
+
+    For correctness and optimal performance, it is always required to use
+    SYNC_START and SYNC_END before and after, respectively, when accessing the
+    mapped address. Userspace cannot rely on coherent access, even when there
+    are systems where it just works without calling these ioctls.

-Mount Options
-=============
-
-When mounting a btrfs filesystem, the following option are accepted.
-Options with (*) are default options and will not show in the mount options.
-
-  alloc_start=<bytes>
-	Debugging option to force all block allocations above a certain
-	byte threshold on each block device.  The value is specified in
-	bytes, optionally with a K, M, or G suffix, case insensitive.
-	Default is 1MB.
-
-  noautodefrag(*)
-  autodefrag
-	Disable/enable auto defragmentation.
-	Auto defragmentation detects small random writes into files and queue
-	them up for the defrag process.  Works best for small files;
-	Not well suited for large database workloads.
-
-  check_int
-  check_int_data
-  check_int_print_mask=<value>
-	These debugging options control the behavior of the integrity checking
-	module (the BTRFS_FS_CHECK_INTEGRITY config option required).
-
-	check_int enables the integrity checker module, which examines all
-	block write requests to ensure on-disk consistency, at a large
-	memory and CPU cost.
-
-	check_int_data includes extent data in the integrity checks, and
-	implies the check_int option.
-
-	check_int_print_mask takes a bitmask of BTRFSIC_PRINT_MASK_* values
-	as defined in fs/btrfs/check-integrity.c, to control the integrity
-	checker module behavior.
-
-	See comments at the top of fs/btrfs/check-integrity.c for more info.
-
-  commit=<seconds>
-	Set the interval of periodic commit, 30 seconds by default. Higher
-	values defer data being synced to permanent storage with obvious
-	consequences when the system crashes. The upper bound is not forced,
-	but a warning is printed if it's more than 300 seconds (5 minutes).
-
-  compress
-  compress=<type>
-  compress-force
-  compress-force=<type>
-	Control BTRFS file data compression.  Type may be specified as "zlib"
-	"lzo" or "no" (for no compression, used for remounting).  If no type
-	is specified, zlib is used.  If compress-force is specified,
-	all files will be compressed, whether or not they compress well.
-	If compression is enabled, nodatacow and nodatasum are disabled.
-
-  degraded
-	Allow mounts to continue with missing devices.  A read-write mount may
-	fail with too many devices missing, for example if a stripe member
-	is completely missing.
-
-  device=<devicepath>
-	Specify a device during mount so that ioctls on the control device
-	can be avoided.  Especially useful when trying to mount a multi-device
-	setup as root.  May be specified multiple times for multiple devices.
-
-  nodiscard(*)
-  discard
-	Disable/enable discard mount option.
-	Discard issues frequent commands to let the block device reclaim space
-	freed by the filesystem.
-	This is useful for SSD devices, thinly provisioned
-	LUNs and virtual machine images, but may have a significant
-	performance impact.  (The fstrim command is also available to
-	initiate batch trims from userspace).
-
-  noenospc_debug(*)
-  enospc_debug
-	Disable/enable debugging option to be more verbose in some ENOSPC conditions.
-
-  fatal_errors=<action>
-	Action to take when encountering a fatal error:
-	  "bug" - BUG() on a fatal error.  This is the default.
-	  "panic" - panic() on a fatal error.
-
-  noflushoncommit(*)
-  flushoncommit
-	The 'flushoncommit' mount option forces any data dirtied by a write in a
-	prior transaction to commit as part of the current commit.  This makes
-	the committed state a fully consistent view of the file system from the
-	application's perspective (i.e., it includes all completed file system
-	operations).  This was previously the behavior only when a snapshot is
-	created.
-
-  inode_cache
-	Enable free inode number caching.   Defaults to off due to an overflow
-	problem when the free space crcs don't fit inside a single page.
-
-  max_inline=<bytes>
-	Specify the maximum amount of space, in bytes, that can be inlined in
-	a metadata B-tree leaf.  The value is specified in bytes, optionally
-	with a K, M, or G suffix, case insensitive.  In practice, this value
-	is limited by the root sector size, with some space unavailable due
-	to leaf headers.  For a 4k sector size, max inline data is ~3900 bytes.
-
-  metadata_ratio=<value>
-	Specify that 1 metadata chunk should be allocated after every <value>
-	data chunks.  Off by default.
-
-  acl(*)
-  noacl
-	Enable/disable support for Posix Access Control Lists (ACLs).  See the
-	acl(5) manual page for more information about ACLs.
-
-  barrier(*)
-  nobarrier
-        Enable/disable the use of block layer write barriers.  Write barriers
-	ensure that certain IOs make it through the device cache and are on
-	persistent storage. If disabled on a device with a volatile
-	(non-battery-backed) write-back cache, nobarrier option will lead to
-	filesystem corruption on a system crash or power loss.
-
-  datacow(*)
-  nodatacow
-	Enable/disable data copy-on-write for newly created files.
-	Nodatacow implies nodatasum, and disables all compression.
-
-  datasum(*)
-  nodatasum
-	Enable/disable data checksumming for newly created files.
-	Datasum implies datacow.
-
-  treelog(*)
-  notreelog
-	Enable/disable the tree logging used for fsync and O_SYNC writes.
-
-  recovery
-	Enable autorecovery attempts if a bad tree root is found at mount time.
-	Currently this scans a list of several previous tree roots and tries to
-	use the first readable.
-
-  rescan_uuid_tree
-	Force check and rebuild procedure of the UUID tree. This should not
-	normally be needed.
-
-  skip_balance
-	Skip automatic resume of interrupted balance operation after mount.
-	May be resumed with "btrfs balance resume."
-
-  space_cache (*)
-	Enable the on-disk freespace cache.
-  nospace_cache
-	Disable freespace cache loading without clearing the cache.
-  clear_cache
-	Force clearing and rebuilding of the disk space cache if something
-	has gone wrong.
-
-  ssd
-  nossd
-  ssd_spread
-	Options to control ssd allocation schemes.  By default, BTRFS will
-	enable or disable ssd allocation heuristics depending on whether a
-	rotational or non-rotational disk is in use.  The ssd and nossd options
-	can override this autodetection.
-
-	The ssd_spread mount option attempts to allocate into big chunks
-	of unused space, and may perform better on low-end ssds.  ssd_spread
-	implies ssd, enabling all other ssd heuristics as well.
-
-  subvol=<path>
-	Mount subvolume at <path> rather than the root subvolume.  <path> is
-	relative to the top level subvolume.
-
-  subvolid=<ID>
-	Mount subvolume specified by an ID number rather than the root subvolume.
-	This allows mounting of subvolumes which are not in the root of the mounted
-	filesystem.
-	You can use "btrfs subvolume list" to see subvolume ID numbers.
-
-  subvolrootid=<objectid> (deprecated)
-	Mount subvolume specified by <objectid> rather than the root subvolume.
-	This allows mounting of subvolumes which are not in the root of the mounted
-	filesystem.
-	You can use "btrfs subvolume show " to see the object ID for a subvolume.
-
-  thread_pool=<number>
-	The number of worker threads to allocate.  The default number is equal
-	to the number of CPUs + 2, or 8, whichever is smaller.
-
-  user_subvol_rm_allowed
-	Allow subvolumes to be deleted by a non-root user. Use with caution.

+pNFS SCSI layout server user guide
+==================================
+
+This document describes support for pNFS SCSI layouts in the Linux NFS server.
+With pNFS SCSI layouts, the NFS server acts as Metadata Server (MDS) for pNFS,
+which in addition to handling all the metadata access to the NFS export,
+also hands out layouts to the clients so that they can directly access the
+underlying SCSI LUNs that are shared with the client.
+
+To use pNFS SCSI layouts with with the Linux NFS server, the exported file
+system needs to support the pNFS SCSI layouts (currently just XFS), and the
+file system must sit on a SCSI LUN that is accessible to the clients in
+addition to the MDS.  As of now the file system needs to sit directly on the
+exported LUN, striping or concatenation of LUNs on the MDS and clients
+is not supported yet.
+
+On a server built with CONFIG_NFSD_SCSI, the pNFS SCSI volume support is
+automatically enabled if the file system is exported using the "pnfs"
+option and the underlying SCSI device support persistent reservations.
+On the client make sure the kernel has the CONFIG_PNFS_BLOCK option
+enabled, and the file system is mounted using the NFSv4.1 protocol
+version (mount -o vers=4.1).

+		    OCFS2 online file check
+		    -----------------------
+
+This document will describe OCFS2 online file check feature.
+
+Introduction
+============
+OCFS2 is often used in high-availaibility systems. However, OCFS2 usually
+converts the filesystem to read-only when encounters an error. This may not be
+necessary, since turning the filesystem read-only would affect other running
+processes as well, decreasing availability.
+Then, a mount option (errors=continue) is introduced, which would return the
+-EIO errno to the calling process and terminate furhter processing so that the
+filesystem is not corrupted further. The filesystem is not converted to
+read-only, and the problematic file's inode number is reported in the kernel
+log. The user can try to check/fix this file via online filecheck feature.
+
+Scope
+=====
+This effort is to check/fix small issues which may hinder day-to-day operations
+of a cluster filesystem by turning the filesystem read-only. The scope of
+checking/fixing is at the file level, initially for regular files and eventually
+to all files (including system files) of the filesystem.
+
+In case of directory to file links is incorrect, the directory inode is
+reported as erroneous.
+
+This feature is not suited for extravagant checks which involve dependency of
+other components of the filesystem, such as but not limited to, checking if the
+bits for file blocks in the allocation has been set. In case of such an error,
+the offline fsck should/would be recommended.
+
+Finally, such an operation/feature should not be automated lest the filesystem
+may end up with more damage than before the repair attempt. So, this has to
+be performed using user interaction and consent.
+
+User interface
+==============
+When there are errors in the OCFS2 filesystem, they are usually accompanied
+by the inode number which caused the error. This inode number would be the
+input to check/fix the file.
+
+There is a sysfs directory for each OCFS2 file system mounting:
+
+  /sys/fs/ocfs2/<devname>/filecheck
+
+Here, <devname> indicates the name of OCFS2 volumn device which has been already
+mounted. The file above would accept inode numbers. This could be used to
+communicate with kernel space, tell which file(inode number) will be checked or
+fixed. Currently, three operations are supported, which includes checking
+inode, fixing inode and setting the size of result record history.
+
+1. If you want to know what error exactly happened to <inode> before fixing, do
+
+  # echo "<inode>" > /sys/fs/ocfs2/<devname>/filecheck/check
+  # cat /sys/fs/ocfs2/<devname>/filecheck/check
+
+The output is like this:
+  INO		DONE	ERROR
+39502		1	GENERATION
+
+<INO> lists the inode numbers.
+<DONE> indicates whether the operation has been finished.
+<ERROR> says what kind of errors was found. For the detailed error numbers,
+please refer to the file linux/fs/ocfs2/filecheck.h.
+
+2. If you determine to fix this inode, do
+
+  # echo "<inode>" > /sys/fs/ocfs2/<devname>/filecheck/fix
+  # cat /sys/fs/ocfs2/<devname>/filecheck/fix
+
+The output is like this:
+  INO		DONE	ERROR
+39502		1	SUCCESS
+
+This time, the <ERROR> column indicates whether this fix is successful or not.
+
+3. The record cache is used to store the history of check/fix results. It's
+defalut size is 10, and can be adjust between the range of 10 ~ 100. You can
+adjust the size like this:
+
+  # echo "<size>" > /sys/fs/ocfs2/<devname>/filecheck/set
+
+Fixing stuff
+============
+On receivng the inode, the filesystem would read the inode and the
+file metadata. In case of errors, the filesystem would fix the errors
+and report the problems it fixed in the kernel log. As a precautionary measure,
+the inode must first be checked for errors before performing a final fix.
+
+The inode and the result history will be maintained temporarily in a
+small linked list buffer which would contain the last (N) inodes
+fixed/checked, the detailed errors which were fixed/checked are printed in the
+kernel log.

+ORANGEFS
+========
+
+OrangeFS is an LGPL userspace scale-out parallel storage system. It is ideal
+for large storage problems faced by HPC, BigData, Streaming Video,
+Genomics, Bioinformatics.
+
+Orangefs, originally called PVFS, was first developed in 1993 by
+Walt Ligon and Eric Blumer as a parallel file system for Parallel
+Virtual Machine (PVM) as part of a NASA grant to study the I/O patterns
+of parallel programs.
+
+Orangefs features include:
+
+  * Distributes file data among multiple file servers
+  * Supports simultaneous access by multiple clients
+  * Stores file data and metadata on servers using local file system
+    and access methods
+  * Userspace implementation is easy to install and maintain
+  * Direct MPI support
+  * Stateless

+
+USERSPACE FILESYSTEM SOURCE
+===========================
+
+http://www.orangefs.org/download
+
+Orangefs versions prior to 2.9.3 would not be compatible with the
+upstream version of the kernel client.
+
+
+BUILDING THE USERSPACE FILESYSTEM ON A SINGLE SERVER
+====================================================
+
+When Orangefs is upstream, "--with-kernel" shouldn't be needed, but
+until then the path to where the kernel with the Orangefs kernel client
+patch was built is needed to ensure that pvfs2-client-core (the bridge
+between kernel space and user space) will build properly. You can omit
+--prefix if you don't care that things are sprinkled around in
+/usr/local.
+
+./configure --prefix=/opt/ofs --with-kernel=/path/to/orangefs/kernel
+
+make
+
+make install
+
+Create an orangefs config file:
+/opt/ofs/bin/pvfs2-genconfig /etc/pvfs2.conf
+
+  for "Enter hostnames", use the hostname, don't let it default to
+  localhost.
+
+create a pvfs2tab file in /etc:
+cat /etc/pvfs2tab
+tcp://myhostname:3334/orangefs /mymountpoint pvfs2 defaults,noauto 0 0
+
+create the mount point you specified in the tab file if needed:
+mkdir /mymountpoint
+
+bootstrap the server:
+/opt/ofs/sbin/pvfs2-server /etc/pvfs2.conf -f
+
+start the server:
+/opt/osf/sbin/pvfs2-server /etc/pvfs2.conf
+
+Now the server is running. At this point you might like to
+prove things are working with:
+
+/opt/osf/bin/pvfs2-ls /mymountpoint
+
+You might not want to enforce selinux, it doesn't seem to matter by
+linux 3.11...
+
+If stuff seems to be working, turn on the client core:
+/opt/osf/sbin/pvfs2-client -p /opt/osf/sbin/pvfs2-client-core
+
+Mount your filesystem.
+mount -t pvfs2 tcp://myhostname:3334/orangefs /mymountpoint
+
+
+OPTIONS
+=======
+
+The following mount options are accepted:
+
+  acl
+    Allow the use of Access Control Lists on files and directories.
+
+  intr
+    Some operations between the kernel client and the user space
+    filesystem can be interruptible, such as changes in debug levels
+    and the setting of tunable parameters.
+
+  local_lock
+    Enable posix locking from the perspective of "this" kernel. The
+    default file_operations lock action is to return ENOSYS. Posix
+    locking kicks in if the filesystem is mounted with -o local_lock.
+    Distributed locking is being worked on for the future.
+
+
+DEBUGGING
+=========
+
+If you want the debug (GOSSIP) statements in a particular
+source file (inode.c for example) go to syslog:
+
+  echo inode > /sys/kernel/debug/orangefs/kernel-debug
+
+No debugging (the default):
+
+  echo none > /sys/kernel/debug/orangefs/kernel-debug
+
+Debugging from several source files:
+
+  echo inode,dir > /sys/kernel/debug/orangefs/kernel-debug
+
+All debugging:
+
+  echo all > /sys/kernel/debug/orangefs/kernel-debug
+
+Get a list of all debugging keywords:
+
+  cat /sys/kernel/debug/orangefs/debug-help
+
+
+PROTOCOL BETWEEN KERNEL MODULE AND USERSPACE
+============================================
+
+Orangefs is a user space filesystem and an associated kernel module.
+We'll just refer to the user space part of Orangefs as "userspace"
+from here on out. Orangefs descends from PVFS, and userspace code
+still uses PVFS for function and variable names. Userspace typedefs
+many of the important structures. Function and variable names in
+the kernel module have been transitioned to "orangefs", and The Linux
+Coding Style avoids typedefs, so kernel module structures that
+correspond to userspace structures are not typedefed.
+
+The kernel module implements a pseudo device that userspace
+can read from and write to. Userspace can also manipulate the
+kernel module through the pseudo device with ioctl.
+
+THE BUFMAP:
+
+At startup userspace allocates two page-size-aligned (posix_memalign)
+mlocked memory buffers, one is used for IO and one is used for readdir
+operations. The IO buffer is 41943040 bytes and the readdir buffer is
+4194304 bytes. Each buffer contains logical chunks, or partitions, and
+a pointer to each buffer is added to its own PVFS_dev_map_desc structure
+which also describes its total size, as well as the size and number of
+the partitions.
+
+A pointer to the IO buffer's PVFS_dev_map_desc structure is sent to a
+mapping routine in the kernel module with an ioctl. The structure is
+copied from user space to kernel space with copy_from_user and is used
+to initialize the kernel module's "bufmap" (struct orangefs_bufmap), which
+then contains:
+
+  * refcnt - a reference counter
+  * desc_size - PVFS2_BUFMAP_DEFAULT_DESC_SIZE (4194304) - the IO buffer's
+    partition size, which represents the filesystem's block size and
+    is used for s_blocksize in super blocks.
+  * desc_count - PVFS2_BUFMAP_DEFAULT_DESC_COUNT (10) - the number of
+    partitions in the IO buffer.
+  * desc_shift - log2(desc_size), used for s_blocksize_bits in super blocks.
+  * total_size - the total size of the IO buffer.
+  * page_count - the number of 4096 byte pages in the IO buffer.
+  * page_array - a pointer to page_count * (sizeof(struct page*)) bytes
+    of kcalloced memory. This memory is used as an array of pointers
+    to each of the pages in the IO buffer through a call to get_user_pages.
+  * desc_array - a pointer to desc_count * (sizeof(struct orangefs_bufmap_desc))
+    bytes of kcalloced memory. This memory is further intialized:
+
+      user_desc is the kernel's copy of the IO buffer's ORANGEFS_dev_map_desc
+      structure. user_desc->ptr points to the IO buffer.
+
+      pages_per_desc = bufmap->desc_size / PAGE_SIZE
+      offset = 0
+
+        bufmap->desc_array[0].page_array = &bufmap->page_array[offset]
+        bufmap->desc_array[0].array_count = pages_per_desc = 1024
+        bufmap->desc_array[0].uaddr = (user_desc->ptr) + (0 * 1024 * 4096)
+        offset += 1024
+                           .
+                           .
+                           .
+        bufmap->desc_array[9].page_array = &bufmap->page_array[offset]
+        bufmap->desc_array[9].array_count = pages_per_desc = 1024
+        bufmap->desc_array[9].uaddr = (user_desc->ptr) +
+                                               (9 * 1024 * 4096)
+        offset += 1024
+
+  * buffer_index_array - a desc_count sized array of ints, used to
+    indicate which of the IO buffer's partitions are available to use.
+  * buffer_index_lock - a spinlock to protect buffer_index_array during update.
+  * readdir_index_array - a five (ORANGEFS_READDIR_DEFAULT_DESC_COUNT) element
+    int array used to indicate which of the readdir buffer's partitions are
+    available to use.
+  * readdir_index_lock - a spinlock to protect readdir_index_array during
+    update.
+
+OPERATIONS:
+
+The kernel module builds an "op" (struct orangefs_kernel_op_s) when it
+needs to communicate with userspace. Part of the op contains the "upcall"
+which expresses the request to userspace. Part of the op eventually
+contains the "downcall" which expresses the results of the request.
+
+The slab allocator is used to keep a cache of op structures handy.
+
+At init time the kernel module defines and initializes a request list
+and an in_progress hash table to keep track of all the ops that are
+in flight at any given time.
+
+Ops are stateful:
+
+ * unknown  - op was just initialized
+ * waiting  - op is on request_list (upward bound)
+ * inprogr  - op is in progress (waiting for downcall)
+ * serviced - op has matching downcall; ok
+ * purged   - op has to start a timer since client-core
+              exited uncleanly before servicing op
+ * given up - submitter has given up waiting for it
+
+When some arbitrary userspace program needs to perform a
+filesystem operation on Orangefs (readdir, I/O, create, whatever)
+an op structure is initialized and tagged with a distinguishing ID
+number. The upcall part of the op is filled out, and the op is
+passed to the "service_operation" function.
+
+Service_operation changes the op's state to "waiting", puts
+it on the request list, and signals the Orangefs file_operations.poll
+function through a wait queue. Userspace is polling the pseudo-device
+and thus becomes aware of the upcall request that needs to be read.
+
+When the Orangefs file_operations.read function is triggered, the
+request list is searched for an op that seems ready-to-process.
+The op is removed from the request list. The tag from the op and
+the filled-out upcall struct are copy_to_user'ed back to userspace.
+
+If any of these (and some additional protocol) copy_to_users fail,
+the op's state is set to "waiting" and the op is added back to
+the request list. Otherwise, the op's state is changed to "in progress",
+and the op is hashed on its tag and put onto the end of a list in the
+in_progress hash table at the index the tag hashed to.
+
+When userspace has assembled the response to the upcall, it
+writes the response, which includes the distinguishing tag, back to
+the pseudo device in a series of io_vecs. This triggers the Orangefs
+file_operations.write_iter function to find the op with the associated
+tag and remove it from the in_progress hash table. As long as the op's
+state is not "canceled" or "given up", its state is set to "serviced".
+The file_operations.write_iter function returns to the waiting vfs,
+and back to service_operation through wait_for_matching_downcall.
+
+Service operation returns to its caller with the op's downcall
+part (the response to the upcall) filled out.
+
+The "client-core" is the bridge between the kernel module and
+userspace. The client-core is a daemon. The client-core has an
+associated watchdog daemon. If the client-core is ever signaled
+to die, the watchdog daemon restarts the client-core. Even though
+the client-core is restarted "right away", there is a period of
+time during such an event that the client-core is dead. A dead client-core
+can't be triggered by the Orangefs file_operations.poll function.
+Ops that pass through service_operation during a "dead spell" can timeout
+on the wait queue and one attempt is made to recycle them. Obviously,
+if the client-core stays dead too long, the arbitrary userspace processes
+trying to use Orangefs will be negatively affected. Waiting ops
+that can't be serviced will be removed from the request list and
+have their states set to "given up". In-progress ops that can't 
+be serviced will be removed from the in_progress hash table and
+have their states set to "given up".
+
+Readdir and I/O ops are atypical with respect to their payloads.
+
+  - readdir ops use the smaller of the two pre-allocated pre-partitioned
+    memory buffers. The readdir buffer is only available to userspace.
+    The kernel module obtains an index to a free partition before launching
+    a readdir op. Userspace deposits the results into the indexed partition
+    and then writes them to back to the pvfs device.
+
+  - io (read and write) ops use the larger of the two pre-allocated
+    pre-partitioned memory buffers. The IO buffer is accessible from
+    both userspace and the kernel module. The kernel module obtains an
+    index to a free partition before launching an io op. The kernel module
+    deposits write data into the indexed partition, to be consumed
+    directly by userspace. Userspace deposits the results of read
+    requests into the indexed partition, to be consumed directly
+    by the kernel module.
+
+Responses to kernel requests are all packaged in pvfs2_downcall_t
+structs. Besides a few other members, pvfs2_downcall_t contains a
+union of structs, each of which is associated with a particular
+response type.
+
+The several members outside of the union are:
+ - int32_t type - type of operation.
+ - int32_t status - return code for the operation.
+ - int64_t trailer_size - 0 unless readdir operation.
+ - char *trailer_buf - initialized to NULL, used during readdir operations.
+
+The appropriate member inside the union is filled out for any
+particular response.
+
+  PVFS2_VFS_OP_FILE_IO
+    fill a pvfs2_io_response_t
+
+  PVFS2_VFS_OP_LOOKUP
+    fill a PVFS_object_kref

+    fill a PVFS_object_kref
+
+  PVFS2_VFS_OP_GETATTR
+    fill in a PVFS_sys_attr_s (tons of stuff the kernel doesn't need)
+    fill in a string with the link target when the object is a symlink.
+
+  PVFS2_VFS_OP_MKDIR
+    fill a PVFS_object_kref
+
+  PVFS2_VFS_OP_STATFS
+    fill a pvfs2_statfs_response_t with useless info <g>. It is hard for
+    us to know, in a timely fashion, these statistics about our
+    distributed network filesystem. 
+
+  PVFS2_VFS_OP_FS_MOUNT
+    fill a pvfs2_fs_mount_response_t which is just like a PVFS_object_kref
+    except its members are in a different order and "__pad1" is replaced
+    with "id".
+
+  PVFS2_VFS_OP_GETXATTR
+    fill a pvfs2_getxattr_response_t
+
+  PVFS2_VFS_OP_LISTXATTR
+    fill a pvfs2_listxattr_response_t
+
+  PVFS2_VFS_OP_PARAM
+    fill a pvfs2_param_response_t
+
+  PVFS2_VFS_OP_PERF_COUNT
+    fill a pvfs2_perf_count_response_t
+
+  PVFS2_VFS_OP_FSKEY
+    file a pvfs2_fs_key_response_t
+
+  PVFS2_VFS_OP_READDIR
+    jamb everything needed to represent a pvfs2_readdir_response_t into
+    the readdir buffer descriptor specified in the upcall.
+
+Userspace uses writev() on /dev/pvfs2-req to pass responses to the requests
+made by the kernel side.
+
+A buffer_list containing:
+  - a pointer to the prepared response to the request from the
+    kernel (struct pvfs2_downcall_t).
+  - and also, in the case of a readdir request, a pointer to a
+    buffer containing descriptors for the objects in the target
+    directory.
+... is sent to the function (PINT_dev_write_list) which performs
+the writev.
+
+PINT_dev_write_list has a local iovec array: struct iovec io_array[10];
+
+The first four elements of io_array are initialized like this for all
+responses:
+
+  io_array[0].iov_base = address of local variable "proto_ver" (int32_t)
+  io_array[0].iov_len = sizeof(int32_t)
+
+  io_array[1].iov_base = address of global variable "pdev_magic" (int32_t)
+  io_array[1].iov_len = sizeof(int32_t)
+  
+  io_array[2].iov_base = address of parameter "tag" (PVFS_id_gen_t)
+  io_array[2].iov_len = sizeof(int64_t)
+
+  io_array[3].iov_base = address of out_downcall member (pvfs2_downcall_t)
+                         of global variable vfs_request (vfs_request_t)
+  io_array[3].iov_len = sizeof(pvfs2_downcall_t)
+
+Readdir responses initialize the fifth element io_array like this:
+
+  io_array[4].iov_base = contents of member trailer_buf (char *)
+                         from out_downcall member of global variable
+                         vfs_request
+  io_array[4].iov_len = contents of member trailer_size (PVFS_size)
+                        from out_downcall member of global variable
+                        vfs_request
+

+Description
+-----------
+
+LTC2990 is a Quad I2C Voltage, Current and Temperature Monitor.
+The chip's inputs can measure 4 voltages, or two inputs together (1+2 and 3+4)
+can be combined to measure a differential voltage, which is typically used to
+measure current through a series resistor, or a temperature.
+
+This driver currently uses the 2x differential mode only. In order to support
+other modes, the driver will need to be expanded.
+
+
+Usage Notes
+-----------
+
+This driver does not probe for PMBus devices. You will have to instantiate
+devices explicitly.
+
+
+Sysfs attributes
+----------------
+
+The "curr*_input" measurements actually report the voltage drop across the
+input pins in microvolts. This is equivalent to the current through a 1mOhm
+sense resistor. Divide the reported value by the actual sense resistor value
+in mOhm to get the actual value.
+
+in0_input     Voltage at Vcc pin in millivolt (range 2.5V to 5V)

+Kernel driver nsa320_hwmon
+==========================

+Supported chips:
+  * Holtek HT46R065 microcontroller with onboard firmware that configures

+    Prefix: 'nsa320'
+    Addresses scanned: none
+    Datasheet: Not available, driver was reverse engineered based upon the
+	Zyxel kernel source
+
+Author:
+  Adam Baker <linux@baker-net.org.uk>
+
+Description
+-----------
+
+This chip is known to be used in the Zyxel NSA320 and NSA325 NAS Units and
+also in some variants of the NSA310 but the driver has only been tested
+on the NSA320. In all of these devices it is connected to the same 3 GPIO
+lines which are used to provide chip select, clock and data lines. The
+interface behaves similarly to SPI but at much lower speeds than are normally
+used for SPI.
+
+Following each chip select pulse the chip will generate a single 32 bit word
+that contains 0x55 as a marker to indicate that data is being read correctly,
+followed by an 8 bit fan speed in 100s of RPM and a 16 bit temperature in
+tenths of a degree.
+
+
+sysfs-Interface
+---------------
+
+temp1_input - temperature input
+fan1_input - fan speed
+
+Notes
+-----
+
+The access timings used in the driver are the same as used in the Zyxel
+provided kernel. Testing has shown that if the delay between chip select and
+the first clock pulse is reduced from 100 ms to just under 10ms then the chip
+will not produce any output. If the duration of either phase of the clock
+is reduced from 100 us to less than 15 us then data pulses are likely to be
+read twice corrupting the output. The above analysis is based upon a sample
+of one unit but suggests that the Zyxel provided delay values include a
+reasonable tolerance.
+
+The driver incorporates a limit that it will not check for updated values
+faster than once a second. This is because the hardware takes a relatively long
+time to read the data from the device and when it does it reads both temp and
+fan speed. As the most likely case for two accesses in quick succession is
+to read both of these values avoiding a second read delay is desirable.

+kcov: code coverage for fuzzing
+===============================
+
+kcov exposes kernel code coverage information in a form suitable for coverage-
+guided fuzzing (randomized testing). Coverage data of a running kernel is
+exported via the "kcov" debugfs file. Coverage collection is enabled on a task
+basis, and thus it can capture precise coverage of a single system call.
+
+Note that kcov does not aim to collect as much coverage as possible. It aims
+to collect more or less stable coverage that is function of syscall inputs.
+To achieve this goal it does not collect coverage in soft/hard interrupts
+and instrumentation of some inherently non-deterministic parts of kernel is
+disbled (e.g. scheduler, locking).
+
+Usage:
+======
+
+Configure kernel with:
+
+        CONFIG_KCOV=y
+
+CONFIG_KCOV requires gcc built on revision 231296 or later.
+Profiling data will only become accessible once debugfs has been mounted:
+
+        mount -t debugfs none /sys/kernel/debug
+
+The following program demonstrates kcov usage from within a test program:
+
+#include <stdio.h>
+#include <stddef.h>
+#include <stdint.h>
+#include <stdlib.h>
+#include <sys/types.h>

+
+If a program needs to collect coverage from several threads (independently),
+it needs to open /sys/kernel/debug/kcov in each thread separately.
+
+The interface is fine-grained to allow efficient forking of test processes.
+That is, a parent process opens /sys/kernel/debug/kcov, enables trace mode,
+mmaps coverage buffer and then forks child processes in a loop. Child processes
+only need to enable coverage (disable happens automatically on thread end).

 General barriers are therefore required to ensure that all CPUs agree

-To reiterate, if your code requires transitivity, use general barriers
-throughout.
+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:
+
+	int u, v, x, y, z;
+
+	void cpu0(void)
+	{
+		r0 = smp_load_acquire(&x);
+		WRITE_ONCE(u, 1);
+		smp_store_release(&y, 1);
+	}
+
+	void cpu1(void)
+	{

+		r4 = READ_ONCE(v);
+		r5 = READ_ONCE(u);

+
+	void cpu3(void)
+	{
+		WRITE_ONCE(v, 1);
+		smp_mb();
+		r3 = READ_ONCE(u);
+	}
+
+Because cpu0(), cpu1(), and cpu2() participate in a local transitive
+chain of smp_store_release()/smp_load_acquire() pairs, the following
+outcome is prohibited:
+
+	r0 == 1 && r1 == 1 && r2 == 1
+
+Furthermore, because of the release-acquire relationship between cpu0()
+and cpu1(), cpu1() must see cpu0()'s writes, so that the following
+outcome is prohibited:
+
+	r1 == 1 && r5 == 0
+
+However, the transitivity of release-acquire is local to the participating
+CPUs and does not apply to cpu3().  Therefore, the following outcome
+is possible:
+
+	r0 == 0 && r1 == 1 && r2 == 1 && r3 == 0 && r4 == 0
+
+As an aside, the following outcome is also possible:
+
+	r0 == 0 && r1 == 1 && r2 == 1 && r3 == 0 && r4 == 0 && r5 == 1
+
+Although cpu0(), cpu1(), and cpu2() will see their respective reads and
+writes in order, CPUs not involved in the release-acquire chain might
+well disagree on the order.  This disagreement stems from the fact that
+the weak memory-barrier instructions used to implement smp_load_acquire()
+and smp_store_release() are not required to order prior stores against
+subsequent loads in all cases.  This means that cpu3() can see cpu0()'s
+store to u as happening -after- cpu1()'s load from v, even though
+both cpu0() and cpu1() agree that these two operations occurred in the
+intended order.
+
+However, please keep in mind that smp_load_acquire() is not magic.
+In particular, it simply reads from its argument with ordering.  It does
+-not- ensure that any particular value will be read.  Therefore, the
+following outcome is possible:
+
+	r0 == 0 && r1 == 0 && r2 == 0 && r5 == 0
+
+Note that this outcome can happen even on a mythical sequentially
+consistent system where nothing is ever reordered.

+Checksum Offloads in the Linux Networking Stack
+
+
+Introduction
+============
+
+This document describes a set of techniques in the Linux networking stack
+ to take advantage of checksum offload capabilities of various NICs.
+
+The following technologies are described:
+ * TX Checksum Offload
+ * LCO: Local Checksum Offload
+ * RCO: Remote Checksum Offload
+
+Things that should be documented here but aren't yet:
+ * RX Checksum Offload
+ * CHECKSUM_UNNECESSARY conversion
+
+
+TX Checksum Offload
+===================
+
+The interface for offloading a transmit checksum to a device is explained
+ in detail in comments near the top of include/linux/skbuff.h.
+In brief, it allows to request the device fill in a single ones-complement
+ checksum defined by the sk_buff fields skb->csum_start and
+ skb->csum_offset.  The device should compute the 16-bit ones-complement
+ checksum (i.e. the 'IP-style' checksum) from csum_start to the end of the
+ packet, and fill in the result at (csum_start + csum_offset).
+Because csum_offset cannot be negative, this ensures that the previous
+ value of the checksum field is included in the checksum computation, thus
+ it can be used to supply any needed corrections to the checksum (such as
+ the sum of the pseudo-header for UDP or TCP).
+This interface only allows a single checksum to be offloaded.  Where
+ encapsulation is used, the packet may have multiple checksum fields in
+ different header layers, and the rest will have to be handled by another
+ mechanism such as LCO or RCO.
+No offloading of the IP header checksum is performed; it is always done in
+ software.  This is OK because when we build the IP header, we obviously
+ have it in cache, so summing it isn't expensive.  It's also rather short.
+The requirements for GSO are more complicated, because when segmenting an
+ encapsulated packet both the inner and outer checksums may need to be
+ edited or recomputed for each resulting segment.  See the skbuff.h comment
+ (section 'E') for more details.
+
+A driver declares its offload capabilities in netdev->hw_features; see
+ Documentation/networking/netdev-features for more.  Note that a device
+ which only advertises NETIF_F_IP[V6]_CSUM must still obey the csum_start
+ and csum_offset given in the SKB; if it tries to deduce these itself in
+ hardware (as some NICs do) the driver should check that the values in the
+ SKB match those which the hardware will deduce, and if not, fall back to
+ checksumming in software instead (with skb_checksum_help or one of the
+ skb_csum_off_chk* functions as mentioned in include/linux/skbuff.h).  This
+ is a pain, but that's what you get when hardware tries to be clever.
+
+The stack should, for the most part, assume that checksum offload is
+ supported by the underlying device.  The only place that should check is
+ validate_xmit_skb(), and the functions it calls directly or indirectly.
+ That function compares the offload features requested by the SKB (which
+ may include other offloads besides TX Checksum Offload) and, if they are
+ not supported or enabled on the device (determined by netdev->features),
+ performs the corresponding offload in software.  In the case of TX
+ Checksum Offload, that means calling skb_checksum_help(skb).
+
+
+LCO: Local Checksum Offload
+===========================
+
+LCO is a technique for efficiently computing the outer checksum of an
+ encapsulated datagram when the inner checksum is due to be offloaded.
+The ones-complement sum of a correctly checksummed TCP or UDP packet is
+ equal to the sum of the pseudo header, because everything else gets
+ 'cancelled out' by the checksum field.  This is because the sum was
+ complemented before being written to the checksum field.
+More generally, this holds in any case where the 'IP-style' ones complement
+ checksum is used, and thus any checksum that TX Checksum Offload supports.
+That is, if we have set up TX Checksum Offload with a start/offset pair, we
+ know that _after the device has filled in that checksum_, the ones
+ complement sum from csum_start to the end of the packet will be equal to
+ _whatever value we put in the checksum field beforehand_.  This allows us
+ to compute the outer checksum without looking at the payload: we simply
+ stop summing when we get to csum_start, then add the 16-bit word at
+ (csum_start + csum_offset).
+Then, when the true inner checksum is filled in (either by hardware or by
+ skb_checksum_help()), the outer checksum will become correct by virtue of
+ the arithmetic.
+
+LCO is performed by the stack when constructing an outer UDP header for an
+ encapsulation such as VXLAN or GENEVE, in udp_set_csum().  Similarly for
+ the IPv6 equivalents, in udp6_set_csum().
+It is also performed when constructing an IPv4 GRE header, in
+ net/ipv4/ip_gre.c:build_header().  It is *not* currently performed when
+ constructing an IPv6 GRE header; the GRE checksum is computed over the
+ whole packet in net/ipv6/ip6_gre.c:ip6gre_xmit2(), but it should be
+ possible to use LCO here as IPv6 GRE still uses an IP-style checksum.
+All of the LCO implementations use a helper function lco_csum(), in
+ include/linux/skbuff.h.
+
+LCO can safely be used for nested encapsulations; in this case, the outer
+ encapsulation layer will sum over both its own header and the 'middle'
+ header.  This does mean that the 'middle' header will get summed multiple
+ times, but there doesn't seem to be a way to avoid that without incurring
+ bigger costs (e.g. in SKB bloat).
+
+
+RCO: Remote Checksum Offload
+============================
+
+RCO is a technique for eliding the inner checksum of an encapsulated
+ datagram, allowing the outer checksum to be offloaded.  It does, however,
+ involve a change to the encapsulation protocols, which the receiver must
+ also support.  For this reason, it is disabled by default.
+RCO is detailed in the following Internet-Drafts:
+https://tools.ietf.org/html/draft-herbert-remotecsumoffload-00
+https://tools.ietf.org/html/draft-herbert-vxlan-rco-00
+In Linux, RCO is implemented individually in each encapsulation protocol,
+ and most tunnel types have flags controlling its use.  For instance, VXLAN
+ has the flag VXLAN_F_REMCSUM_TX (per struct vxlan_rdst) to indicate that
+ RCO should be used when transmitting to a given remote destination.

+
+KCM sockets
+-----------
+
+The KCM sockets provide the user interface to the muliplexor. All the KCM sockets
+bound to a multiplexor are considered to have equivalent function, and I/O
+operations in different sockets may be done in parallel without the need for
+synchronization between threads in userspace.
+
+Multiplexor
+-----------
+
+The multiplexor provides the message steering. In the transmit path, messages
+written on a KCM socket are sent atomically on an appropriate TCP socket.
+Similarly, in the receive path, messages are constructed on each TCP socket
+(Psock) and complete messages are steered to a KCM socket.
+
+TCP sockets & Psocks
+--------------------
+
+TCP sockets may be bound to a KCM multiplexor. A Psock structure is allocated
+for each bound TCP socket, this structure holds the state for constructing
+messages on receive as well as other connection specific information for KCM.
+
+Connected mode semantics
+------------------------
+
+Each multiplexor assumes that all attached TCP connections are to the same
+destination and can use the different connections for load balancing when
+transmitting. The normal send and recv calls (include sendmmsg and recvmmsg)
+can be used to send and receive messages from the KCM socket.
+
+Socket types
+------------
+
+KCM supports SOCK_DGRAM and SOCK_SEQPACKET socket types.
+
+Message delineation
+-------------------
+
+Messages are sent over a TCP stream with some application protocol message
+format that typically includes a header which frames the messages. The length
+of a received message can be deduced from the application protocol header
+(often just a simple length field).
+
+A TCP stream must be parsed to determine message boundaries. Berkeley Packet
+Filter (BPF) is used for this. When attaching a TCP socket to a multiplexor a
+BPF program must be specified. The program is called at the start of receiving
+a new message and is given an skbuff that contains the bytes received so far.
+It parses the message header and returns the length of the message. Given this
+information, KCM will construct the message of the stated length and deliver it
+to a KCM socket.
+
+TCP socket management
+---------------------
+
+When a TCP socket is attached to a KCM multiplexor data ready (POLLIN) and
+write space available (POLLOUT) events are handled by the multiplexor. If there
+is a state change (disconnection) or other error on a TCP socket, an error is
+posted on the TCP socket so that a POLLERR event happens and KCM discontinues
+using the socket. When the application gets the error notification for a
+TCP socket, it should unattach the socket from KCM and then handle the error
+condition (the typical response is to close the socket and create a new
+connection if necessary).
+
+KCM limits the maximum receive message size to be the size of the receive
+socket buffer on the attached TCP socket (the socket buffer size can be set by
+SO_RCVBUF). If the length of a new message reported by the BPF program is
+greater than this limit a corresponding error (EMSGSIZE) is posted on the TCP
+socket. The BPF program may also enforce a maximum messages size and report an
+error when it is exceeded.
+
+A timeout may be set for assembling messages on a receive socket. The timeout
+value is taken from the receive timeout of the attached TCP socket (this is set
+by SO_RCVTIMEO). If the timer expires before assembly is complete an error
+(ETIMEDOUT) is posted on the socket.
+
+User interface
+==============
+
+Creating a multiplexor
+----------------------
+
+A new multiplexor and initial KCM socket is created by a socket call:
+
+  socket(AF_KCM, type, protocol)
+
+  - type is either SOCK_DGRAM or SOCK_SEQPACKET
+  - protocol is KCMPROTO_CONNECTED
+
+Cloning KCM sockets
+-------------------
+
+After the first KCM socket is created using the socket call as described
+above, additional sockets for the multiplexor can be created by cloning
+a KCM socket. This is accomplished by an ioctl on a KCM socket:
+
+  /* From linux/kcm.h */
+  struct kcm_clone {
+        int fd;
+  };
+
+  struct kcm_clone info;
+
+  memset(&info, 0, sizeof(info));
+
+  err = ioctl(kcmfd, SIOCKCMCLONE, &info);
+
+  if (!err)
+    newkcmfd = info.fd;
+
+Attach transport sockets
+------------------------
+
+Attaching of transport sockets to a multiplexor is performed by calling an
+ioctl on a KCM socket for the multiplexor. e.g.:
+
+  /* From linux/kcm.h */
+  struct kcm_attach {
+        int fd;
+	int bpf_fd;
+  };
+
+  struct kcm_attach info;
+
+  memset(&info, 0, sizeof(info));
+
+  info.fd = tcpfd;
+  info.bpf_fd = bpf_prog_fd;
+
+  ioctl(kcmfd, SIOCKCMATTACH, &info);
+
+The kcm_attach structure contains:
+  fd: file descriptor for TCP socket being attached
+  bpf_prog_fd: file descriptor for compiled BPF program downloaded
+
+Unattach transport sockets
+--------------------------
+
+Unattaching a transport socket from a multiplexor is straightforward. An
+"unattach" ioctl is done with the kcm_unattach structure as the argument:
+
+  /* From linux/kcm.h */
+  struct kcm_unattach {
+        int fd;
+  };
+
+  struct kcm_unattach info;
+
+  memset(&info, 0, sizeof(info));
+
+  info.fd = cfd;
+
+  ioctl(fd, SIOCKCMUNATTACH, &info);
+
+Disabling receive on KCM socket
+-------------------------------
+
+A setsockopt is used to disable or enable receiving on a KCM socket.
+When receive is disabled, any pending messages in the socket's
+receive buffer are moved to other sockets. This feature is useful
+if an application thread knows that it will be doing a lot of
+work on a request and won't be able to service new messages for a
+while. Example use:
+
+  int val = 1;
+
+  setsockopt(kcmfd, SOL_KCM, KCM_RECV_DISABLE, &val, sizeof(val))
+
+BFP programs for message delineation
+------------------------------------
+
+BPF programs can be compiled using the BPF LLVM backend. For exmple,
+the BPF program for parsing Thrift is:
+
+  #include "bpf.h" /* for __sk_buff */
+  #include "bpf_helpers.h" /* for load_word intrinsic */
+
+  SEC("socket_kcm")
+  int bpf_prog1(struct __sk_buff *skb)
+  {
+       return load_word(skb, 0) + 4;
+  }
+
+  char _license[] SEC("license") = "GPL";
+
+Use in applications
+===================
+
+KCM accelerates application layer protocols. Specifically, it allows
+applications to use a message based interface for sending and receiving
+messages. The kernel provides necessary assurances that messages are sent
+and received atomically. This relieves much of the burden applications have
+in mapping a message based protocol onto the TCP stream. KCM also make
+application layer messages a unit of work in the kernel for the purposes of
+steerng and scheduling, which in turn allows a simpler networking model in
+multithreaded applications.
+
+Configurations
+--------------
+
+In an Nx1 configuration, KCM logically provides multiple socket handles
+to the same TCP connection. This allows parallelism between in I/O
+operations on the TCP socket (for instance copyin and copyout of data is
+parallelized). In an application, a KCM socket can be opened for each
+processing thread and inserted into the epoll (similar to how SO_REUSEPORT
+is used to allow multiple listener sockets on the same port).
+
+In a MxN configuration, multiple connections are established to the
+same destination. These are used for simple load balancing.
+
+Message batching
+----------------
+
+The primary purpose of KCM is load balancing between KCM sockets and hence
+threads in a nominal use case. Perfect load balancing, that is steering
+each received message to a different KCM socket or steering each sent
+message to a different TCP socket, can negatively impact performance
+since this doesn't allow for affinities to be established. Balancing
+based on groups, or batches of messages, can be beneficial for performance.
+
+On transmit, there are three ways an application can batch (pipeline)
+messages on a KCM socket.
+  1) Send multiple messages in a single sendmmsg.
+  2) Send a group of messages each with a sendmsg call, where all messages
+     except the last have MSG_BATCH in the flags of sendmsg call.
+  3) Create "super message" composed of multiple messages and send this
+     with a single sendmsg.
+
+On receive, the KCM module attempts to queue messages received on the
+same KCM socket during each TCP ready callback. The targeted KCM socket
+changes at each receive ready callback on the KCM socket. The application
+does not need to configure this.
+
+Error handling
+--------------
+
+An application should include a thread to monitor errors raised on
+the TCP connection. Normally, this will be done by placing each
+TCP socket attached to a KCM multiplexor in epoll set for POLLERR
+event. If an error occurs on an attached TCP socket, KCM sets an EPIPE
+on the socket thus waking up the application thread. When the application
+sees the error (which may just be a disconnect) it should unattach the
+socket from KCM and then close it. It is assumed that once an error is
+posted on the TCP socket the data stream is unrecoverable (i.e. an error
+may have occurred in in the middle of receiving a messssge).
+
+TCP connection monitoring
+-------------------------
+
+In KCM there is no means to correlate a message to the TCP socket that
+was used to send or receive the message (except in the case there is
+only one attached TCP socket). However, the application does retain
+an open file descriptor to the socket so it will be able to get statistics
+from the socket which can be used in detecting issues (such as high
+retransmissions on the socket).

-This file documents how to use memory mapped I/O with netlink.
-
-Author: Patrick McHardy <kaber@trash.net>
-
-Overview
---------
-
-Memory mapped netlink I/O can be used to increase throughput and decrease
-overhead of unicast receive and transmit operations. Some netlink subsystems
-require high throughput, these are mainly the netfilter subsystems
-nfnetlink_queue and nfnetlink_log, but it can also help speed up large
-dump operations of f.i. the routing database.
-
-Memory mapped netlink I/O used two circular ring buffers for RX and TX which
-are mapped into the processes address space.
-
-The RX ring is used by the kernel to directly construct netlink messages into
-user-space memory without copying them as done with regular socket I/O,
-additionally as long as the ring contains messages no recvmsg() or poll()
-syscalls have to be issued by user-space to get more message.
-
-The TX ring is used to process messages directly from user-space memory, the
-kernel processes all messages contained in the ring using a single sendmsg()
-call.
-
-Usage overview
---------------
-
-In order to use memory mapped netlink I/O, user-space needs three main changes:
-
-- ring setup
-- conversion of the RX path to get messages from the ring instead of recvmsg()
-- conversion of the TX path to construct messages into the ring
-
-Ring setup is done using setsockopt() to provide the ring parameters to the
-kernel, then a call to mmap() to map the ring into the processes address space:
-
-- setsockopt(fd, SOL_NETLINK, NETLINK_RX_RING, &params, sizeof(params));
-- setsockopt(fd, SOL_NETLINK, NETLINK_TX_RING, &params, sizeof(params));
-- ring = mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0)
-
-Usage of either ring is optional, but even if only the RX ring is used the
-mapping still needs to be writable in order to update the frame status after
-processing.
-
-Conversion of the reception path involves calling poll() on the file
-descriptor, once the socket is readable the frames from the ring are
-processed in order until no more messages are available, as indicated by
-a status word in the frame header.
-
-On kernel side, in order to make use of memory mapped I/O on receive, the
-originating netlink subsystem needs to support memory mapped I/O, otherwise
-it will use an allocated socket buffer as usual and the contents will be
- copied to the ring on transmission, nullifying most of the performance gains.
-Dumps of kernel databases automatically support memory mapped I/O.
-
-Conversion of the transmit path involves changing message construction to
-use memory from the TX ring instead of (usually) a buffer declared on the
-stack and setting up the frame header appropriately. Optionally poll() can
-be used to wait for free frames in the TX ring.
-
-Structured and definitions for using memory mapped I/O are contained in
-<linux/netlink.h>.
-
-RX and TX rings
-----------------
-
-Each ring contains a number of continuous memory blocks, containing frames of
-fixed size dependent on the parameters used for ring setup.
-
-Ring:	[ block 0 ]
-		[ frame 0 ]
-		[ frame 1 ]
-	[ block 1 ]
-		[ frame 2 ]
-		[ frame 3 ]
-	...
-	[ block n ]
-		[ frame 2 * n ]
-		[ frame 2 * n + 1 ]
-
-The blocks are only visible to the kernel, from the point of view of user-space
-the ring just contains the frames in a continuous memory zone.
-
-The ring parameters used for setting up the ring are defined as follows:
-
-struct nl_mmap_req {
-	unsigned int	nm_block_size;
-	unsigned int	nm_block_nr;
-	unsigned int	nm_frame_size;
-	unsigned int	nm_frame_nr;
-};
-
-Frames are grouped into blocks, where each block is a continuous region of memory
-and holds nm_block_size / nm_frame_size frames. The total number of frames in
-the ring is nm_frame_nr. The following invariants hold:
-
-- frames_per_block = nm_block_size / nm_frame_size
-
-- nm_frame_nr = frames_per_block * nm_block_nr
-
-Some parameters are constrained, specifically:
-
-- nm_block_size must be a multiple of the architectures memory page size.
-  The getpagesize() function can be used to get the page size.
-
-- nm_frame_size must be equal or larger to NL_MMAP_HDRLEN, IOW a frame must be
-  able to hold at least the frame header
-
-- nm_frame_size must be smaller or equal to nm_block_size
-
-- nm_frame_size must be a multiple of NL_MMAP_MSG_ALIGNMENT
-
-- nm_frame_nr must equal the actual number of frames as specified above.
-
-When the kernel can't allocate physically continuous memory for a ring block,
-it will fall back to use physically discontinuous memory. This might affect
-performance negatively, in order to avoid this the nm_frame_size parameter
-should be chosen to be as small as possible for the required frame size and
-the number of blocks should be increased instead.
-
-Ring frames
-------------
-
-Each frames contain a frame header, consisting of a synchronization word and some
-meta-data, and the message itself.
-
-Frame:	[ header message ]
-
-The frame header is defined as follows:
-
-struct nl_mmap_hdr {
-	unsigned int	nm_status;
-	unsigned int	nm_len;
-	__u32		nm_group;
-	/* credentials */
-	__u32		nm_pid;
-	__u32		nm_uid;
-	__u32		nm_gid;
-};
-
-- nm_status is used for synchronizing processing between the kernel and user-
-  space and specifies ownership of the frame as well as the operation to perform
-
-- nm_len contains the length of the message contained in the data area
-
-- nm_group specified the destination multicast group of message
-
-- nm_pid, nm_uid and nm_gid contain the netlink pid, UID and GID of the sending
-  process. These values correspond to the data available using SOCK_PASSCRED in
-  the SCM_CREDENTIALS cmsg.
-
-The possible values in the status word are:
-
-- NL_MMAP_STATUS_UNUSED:
-	RX ring:	frame belongs to the kernel and contains no message
-			for user-space. Approriate action is to invoke poll()
-			to wait for new messages.
-
-	TX ring:	frame belongs to user-space and can be used for
-			message construction.
-
-- NL_MMAP_STATUS_RESERVED:
-	RX ring only:	frame is currently used by the kernel for message
-			construction and contains no valid message yet.
-			Appropriate action is to invoke poll() to wait for
-			new messages.
-
-- NL_MMAP_STATUS_VALID:
-	RX ring:	frame contains a valid message. Approriate action is
-			to process the message and release the frame back to
-			the kernel by setting the status to
-			NL_MMAP_STATUS_UNUSED or queue the frame by setting the
-			status to NL_MMAP_STATUS_SKIP.
-
-	TX ring:	the frame contains a valid message from user-space to
-			be processed by the kernel. After completing processing
-			the kernel will release the frame back to user-space by
-			setting the status to NL_MMAP_STATUS_UNUSED.
-
-- NL_MMAP_STATUS_COPY:
-	RX ring only:	a message is ready to be processed but could not be
-			stored in the ring, either because it exceeded the
-			frame size or because the originating subsystem does
-			not support memory mapped I/O. Appropriate action is
-			to invoke recvmsg() to receive the message and release
-			the frame back to the kernel by setting the status to
-			NL_MMAP_STATUS_UNUSED.
-
-- NL_MMAP_STATUS_SKIP:
-	RX ring only:	user-space queued the message for later processing, but
-			processed some messages following it in the ring. The
-			kernel should skip this frame when looking for unused
-			frames.
-
-The data area of a frame begins at a offset of NL_MMAP_HDRLEN relative to the
-frame header.
-
-TX limitations
---------------
-
-As of Jan 2015 the message is always copied from the ring frame to an
-allocated buffer due to unresolved security concerns.
-See commit 4682a0358639b29cf ("netlink: Always copy on mmap TX.").

+RapidIO subsystem mport character device driver (rio_mport_cdev.c)
+==================================================================
+
+Version History:
+----------------
+  1.0.0 - Initial driver release.
+
+==================================================================
+
+I. Overview
+
+This device driver is the result of collaboration within the RapidIO.org
+Software Task Group (STG) between Texas Instruments, Freescale,
+Prodrive Technologies, Nokia Networks, BAE and IDT.  Additional input was
+received from other members of RapidIO.org. The objective was to create a
+character mode driver interface which exposes the capabilities of RapidIO
+devices directly to applications, in a manner that allows the numerous and
+varied RapidIO implementations to interoperate.
+
+This driver (MPORT_CDEV) provides access to basic RapidIO subsystem operations
+for user-space applications. Most of RapidIO operations are supported through
+'ioctl' system calls.
+
+When loaded this device driver creates filesystem nodes named rio_mportX in /dev
+directory for each registered RapidIO mport device. 'X' in the node name matches
+to unique port ID assigned to each local mport device.
+
+Using available set of ioctl commands user-space applications can perform
+following RapidIO bus and subsystem operations:
+
+- Reads and writes from/to configuration registers of mport devices
+    (RIO_MPORT_MAINT_READ_LOCAL/RIO_MPORT_MAINT_WRITE_LOCAL)
+- Reads and writes from/to configuration registers of remote RapidIO devices.
+  This operations are defined as RapidIO Maintenance reads/writes in RIO spec.
+    (RIO_MPORT_MAINT_READ_REMOTE/RIO_MPORT_MAINT_WRITE_REMOTE)
+- Set RapidIO Destination ID for mport devices (RIO_MPORT_MAINT_HDID_SET)
+- Set RapidIO Component Tag for mport devices (RIO_MPORT_MAINT_COMPTAG_SET)
+- Query logical index of mport devices (RIO_MPORT_MAINT_PORT_IDX_GET)
+- Query capabilities and RapidIO link configuration of mport devices
+    (RIO_MPORT_GET_PROPERTIES)
+- Enable/Disable reporting of RapidIO doorbell events to user-space applications
+    (RIO_ENABLE_DOORBELL_RANGE/RIO_DISABLE_DOORBELL_RANGE)
+- Enable/Disable reporting of RIO port-write events to user-space applications
+    (RIO_ENABLE_PORTWRITE_RANGE/RIO_DISABLE_PORTWRITE_RANGE)
+- Query/Control type of events reported through this driver: doorbells,
+  port-writes or both (RIO_SET_EVENT_MASK/RIO_GET_EVENT_MASK)
+- Configure/Map mport's outbound requests window(s) for specific size,
+  RapidIO destination ID, hopcount and request type
+    (RIO_MAP_OUTBOUND/RIO_UNMAP_OUTBOUND)
+- Configure/Map mport's inbound requests window(s) for specific size,
+  RapidIO base address and local memory base address
+    (RIO_MAP_INBOUND/RIO_UNMAP_INBOUND)
+- Allocate/Free contiguous DMA coherent memory buffer for DMA data transfers
+  to/from remote RapidIO devices (RIO_ALLOC_DMA/RIO_FREE_DMA)
+- Initiate DMA data transfers to/from remote RapidIO devices (RIO_TRANSFER).
+  Supports blocking, asynchronous and posted (a.k.a 'fire-and-forget') data
+  transfer modes.
+- Check/Wait for completion of asynchronous DMA data transfer
+    (RIO_WAIT_FOR_ASYNC)
+- Manage device objects supported by RapidIO subsystem (RIO_DEV_ADD/RIO_DEV_DEL).
+  This allows implementation of various RapidIO fabric enumeration algorithms
+  as user-space applications while using remaining functionality provided by
+  kernel RapidIO subsystem.
+
+II. Hardware Compatibility
+
+This device driver uses standard interfaces defined by kernel RapidIO subsystem
+and therefore it can be used with any mport device driver registered by RapidIO
+subsystem with limitations set by available mport implementation.
+
+At this moment the most common limitation is availability of RapidIO-specific
+DMA engine framework for specific mport device. Users should verify available
+functionality of their platform when planning to use this driver:
+
+- IDT Tsi721 PCIe-to-RapidIO bridge device and its mport device driver are fully
+  compatible with this driver.
+- Freescale SoCs 'fsl_rio' mport driver does not have implementation for RapidIO
+  specific DMA engine support and therefore DMA data transfers mport_cdev driver
+  are not available.
+
+III. Module parameters
+
+- 'dbg_level' - This parameter allows to control amount of debug information
+        generated by this device driver. This parameter is formed by set of
+        This parameter can be changed bit masks that correspond to the specific
+        functional block.
+        For mask definitions see 'drivers/rapidio/devices/rio_mport_cdev.c'
+        This parameter can be changed dynamically.
+        Use CONFIG_RAPIDIO_DEBUG=y to enable debug output at the top level.
+
+IV. Known problems
+
+  None.
+
+V. User-space Applications and API
+
+API library and applications that use this device driver are available from
+RapidIO.org.
+
+VI. TODO List
+
+- Add support for sending/receiving "raw" RapidIO messaging packets.
+- Add memory mapped DMA data transfers as an option when RapidIO-specific DMA
+  is not available.

+To support DP MST audio, HD Audio hdmi codec driver introduces virtual pin
+and dynamic pcm assignment.
+
+Virtual pin is an extension of per_pin. The most difference of DP MST
+from legacy is that DP MST introduces device entry. Each pin can contain
+several device entries. Each device entry behaves as a pin.
+
+As each pin may contain several device entries and each codec may contain
+several pins, if we use one pcm per per_pin, there will be many PCMs.
+The new solution is to create a few PCMs and to dynamically bind pcm to
+per_pin. Driver uses spec->dyn_pcm_assign flag to indicate whether to use
+the new solution.
+
+PCM
+===
+To be added
+
+
+Jack
+====
+
+Presume:
+ - MST must be dyn_pcm_assign, and it is acomp (for Intel scenario);
+ - NON-MST may or may not be dyn_pcm_assign, it can be acomp or !acomp;
+
+So there are the following scenarios:
+ a. MST (&& dyn_pcm_assign && acomp)
+ b. NON-MST && dyn_pcm_assign && acomp
+ c. NON-MST && !dyn_pcm_assign && !acomp
+
+Below discussion will ignore MST and NON-MST difference as it doesn't
+impact on jack handling too much.
+
+Driver uses struct hdmi_pcm pcm[] array in hdmi_spec and snd_jack is
+a member of hdmi_pcm. Each pin has one struct hdmi_pcm * pcm pointer.
+
+For !dyn_pcm_assign, per_pin->pcm will assigned to spec->pcm[n] statically.
+
+For dyn_pcm_assign, per_pin->pcm will assigned to spec->pcm[n]
+when monitor is hotplugged.
+
+
+Build Jack
+----------
+
+- dyn_pcm_assign
+Will not use hda_jack but use snd_jack in spec->pcm_rec[pcm_idx].jack directly.
+
+- !dyn_pcm_assign
+Use hda_jack and assign spec->pcm_rec[pcm_idx].jack = jack->jack statically.
+
+
+Unsolicited Event Enabling
+--------------------------
+Enable unsolicited event if !acomp.
+
+
+Monitor Hotplug Event Handling
+------------------------------
+- acomp
+pin_eld_notify() -> check_presence_and_report() -> hdmi_present_sense() ->
+sync_eld_via_acomp().
+Use directly snd_jack_report() on spec->pcm_rec[pcm_idx].jack for
+both dyn_pcm_assign and !dyn_pcm_assign
+
+- !acomp
+Hdmi_unsol_event() -> hdmi_intrinsic_event() -> check_presence_and_report() ->
+hdmi_present_sense() -> hdmi_prepsent_sense_via_verbs()
+Use directly snd_jack_report() on spec->pcm_rec[pcm_idx].jack for dyn_pcm_assign.
+Use hda_jack mechanism to handle jack events.

+4.97 KVM_CAP_PPC_MULTITCE
+
+Capability: KVM_CAP_PPC_MULTITCE
+Architectures: ppc
+Type: vm
+
+This capability means the kernel is capable of handling hypercalls
+H_PUT_TCE_INDIRECT and H_STUFF_TCE without passing those into the user
+space. This significantly accelerates DMA operations for PPC KVM guests.
+User space should expect that its handlers for these hypercalls
+are not going to be called if user space previously registered LIOBN
+in KVM (via KVM_CREATE_SPAPR_TCE or similar calls).
+
+In order to enable H_PUT_TCE_INDIRECT and H_STUFF_TCE use in the guest,
+user space might have to advertise it for the guest. For example,
+IBM pSeries (sPAPR) guest starts using them if "hcall-multi-tce" is
+present in the "ibm,hypertas-functions" device-tree property.
+
+The hypercalls mentioned above may or may not be processed successfully
+in the kernel based fast path. If they can not be handled by the kernel,
+they will get passed on to user space. So user space still has to have
+an implementation for these despite the in kernel acceleration.
+
+This capability is always enabled.

+
+This is an extension for KVM_CAP_SPAPR_TCE which only supports 32bit
+windows, described in 4.62 KVM_CREATE_SPAPR_TCE
+
+This capability uses extended struct in ioctl interface:

+	__u32 page_shift;
+	__u32 flags;
+	__u64 offset;	/* in pages */
+	__u64 size; 	/* in pages */
+};
+
+The aim of extension is to support an additional bigger DMA window with
+a variable page size.
+KVM_CREATE_SPAPR_TCE_64 receives a 64bit window size, an IOMMU page shift and
+a bus offset of the corresponding DMA window, @size and @offset are numbers
+of IOMMU pages.

+x86 Topology
+============
+
+This documents and clarifies the main aspects of x86 topology modelling and
+representation in the kernel. Update/change when doing changes to the
+respective code.
+
+The architecture-agnostic topology definitions are in
+Documentation/cputopology.txt. This file holds x86-specific
+differences/specialities which must not necessarily apply to the generic
+definitions. Thus, the way to read up on Linux topology on x86 is to start
+with the generic one and look at this one in parallel for the x86 specifics.
+
+Needless to say, code should use the generic functions - this file is *only*
+here to *document* the inner workings of x86 topology.
+
+Started by Thomas Gleixner <tglx@linutronix.de> and Borislav Petkov <bp@alien8.de>.
+
+The main aim of the topology facilities is to present adequate interfaces to
+code which needs to know/query/use the structure of the running system wrt
+threads, cores, packages, etc.
+
+The kernel does not care about the concept of physical sockets because a
+socket has no relevance to software. It's an electromechanical component. In
+the past a socket always contained a single package (see below), but with the
+advent of Multi Chip Modules (MCM) a socket can hold more than one package. So
+there might be still references to sockets in the code, but they are of
+historical nature and should be cleaned up.
+
+The topology of a system is described in the units of:
+
+    - packages
+    - cores
+    - threads
+
+* Package:
+
+  Packages contain a number of cores plus shared resources, e.g. DRAM
+  controller, shared caches etc.
+
+  AMD nomenclature for package is 'Node'.
+
+  Package-related topology information in the kernel:
+
+  - cpuinfo_x86.x86_max_cores:
+
+    The number of cores in a package. This information is retrieved via CPUID.
+
+  - cpuinfo_x86.phys_proc_id:
+
+    The physical ID of the package. This information is retrieved via CPUID
+    and deduced from the APIC IDs of the cores in the package.
+
+  - cpuinfo_x86.logical_id:
+
+    The logical ID of the package. As we do not trust BIOSes to enumerate the
+    packages in a consistent way, we introduced the concept of logical package
+    ID so we can sanely calculate the number of maximum possible packages in
+    the system and have the packages enumerated linearly.
+
+  - topology_max_packages():
+
+    The maximum possible number of packages in the system. Helpful for per
+    package facilities to preallocate per package information.
+
+
+* Cores:
+
+  A core consists of 1 or more threads. It does not matter whether the threads
+  are SMT- or CMT-type threads.
+
+  AMDs nomenclature for a CMT core is "Compute Unit". The kernel always uses
+  "core".
+
+  Core-related topology information in the kernel:
+
+  - smp_num_siblings:
+
+    The number of threads in a core. The number of threads in a package can be
+    calculated by:
+
+	threads_per_package = cpuinfo_x86.x86_max_cores * smp_num_siblings
+
+
+* Threads:
+
+  A thread is a single scheduling unit. It's the equivalent to a logical Linux
+  CPU.
+
+  AMDs nomenclature for CMT threads is "Compute Unit Core". The kernel always
+  uses "thread".
+
+  Thread-related topology information in the kernel:
+
+  - topology_core_cpumask():
+
+    The cpumask contains all online threads in the package to which a thread
+    belongs.
+
+    The number of online threads is also printed in /proc/cpuinfo "siblings."
+
+  - topology_sibling_mask():
+
+    The cpumask contains all online threads in the core to which a thread
+    belongs.
+
+   - topology_logical_package_id():
+
+    The logical package ID to which a thread belongs.
+
+   - topology_physical_package_id():
+
+    The physical package ID to which a thread belongs.
+
+   - topology_core_id();
+
+    The ID of the core to which a thread belongs. It is also printed in /proc/cpuinfo
+    "core_id."
+
+
+
+System topology examples
+
+Note:
+
+The alternative Linux CPU enumeration depends on how the BIOS enumerates the
+threads. Many BIOSes enumerate all threads 0 first and then all threads 1.
+That has the "advantage" that the logical Linux CPU numbers of threads 0 stay
+the same whether threads are enabled or not. That's merely an implementation
+detail and has no practical impact.

+                芯片勘误和软件补救措施
+                ==================
+
+作者: Will Deacon <will.deacon@arm.com>
+日期: 2015年11月27日
+
+一个不幸的现实：硬件经常带有一些所谓的“瑕疵（errata）”，导致其在
+某些特定情况下会违背构架定义的行为。就基于 ARM 的硬件而言，这些瑕疵
+大体可分为以下几类：
+
+  A 类：无可行补救措施的严重缺陷。
+  B 类：有可接受的补救措施的重大或严重缺陷。
+  C 类：在正常操作中不会显现的小瑕疵。
+
+更多资讯，请在 infocenter.arm.com （需注册）中查阅“软件开发者勘误
+笔记”（“Software Developers Errata Notice”）文档。
+
+对于 Linux 而言，B 类缺陷可能需要操作系统的某些特别处理。例如，避免
+一个特殊的代码序列，或是以一种特定的方式配置处理器。在某种不太常见的
+情况下，为将 A 类缺陷当作 C 类处理，可能需要用类似的手段。这些手段被
+统称为“软件补救措施”，且仅在少数情况需要（例如，那些需要一个运行在
+非安全异常级的补救措施 *并且* 能被 Linux 触发的情况）。
+
+对于尚在讨论中的可能对未受瑕疵影响的系统产生干扰的软件补救措施，有一个
+相应的内核配置（Kconfig）选项被加在 “内核特性（Kernel Features）”->
+“基于可选方法框架的 ARM 瑕疵补救措施（ARM errata workarounds via
+the alternatives framework）"。这些选项被默认开启，若探测到受影响的CPU，
+补丁将在运行时被使用。至于对系统运行影响较小的补救措施，内核配置选项
+并不存在，且代码以某种规避瑕疵的方式被构造（带注释为宜）。
+
+这种做法对于在任意内核源代码树中准确地判断出哪个瑕疵已被软件方法所补救
+稍微有点麻烦，所以在 Linux 内核中此文件作为软件补救措施的注册表，
+并将在新的软件补救措施被提交和向后移植（backported）到稳定内核时被更新。

+/********************************************************************
+ * Hypervisor exception vector and handlers
+ *
+ *
+ * The KVM/ARM Hypervisor ABI is defined as follows:
+ *
+ * Entry to Hyp mode from the host kernel will happen _only_ when an HVC
+ * instruction is issued since all traps are disabled when running the host
+ * kernel as per the Hyp-mode initialization at boot time.
+ *
+ * HVC instructions cause a trap to the vector page + offset 0x14 (see hyp_hvc
+ * below) when the HVC instruction is called from SVC mode (i.e. a guest or the
+ * host kernel) and they cause a trap to the vector page + offset 0x8 when HVC
+ * instructions are called from within Hyp-mode.
+ *
+ * Hyp-ABI: Calling HYP-mode functions from host (in SVC mode):
+ *    Switching to Hyp mode is done through a simple HVC #0 instruction. The
+ *    exception vector code will check that the HVC comes from VMID==0.
+ *    - r0 contains a pointer to a HYP function
+ *    - r1, r2, and r3 contain arguments to the above function.
+ *    - The HYP function will be called with its arguments in r0, r1 and r2.
+ *    On HYP function return, we return directly to SVC.
+ *
+ * Note that the above is used to execute code in Hyp-mode from a host-kernel
+ * point of view, and is a different concept from performing a world-switch and
+ * executing guest code SVC mode (with a VMID != 0).

- *    On HYP function return, we return directly to SVC.

- * LPC32xx clock management driver overview
- *
- * The LPC32XX contains a number of high level system clocks that can be
- * generated from different sources. These system clocks are used to
- * generate the CPU and bus rates and the individual peripheral clocks in
- * the system. When Linux is started by the boot loader, the system
- * clocks are already running. Stopping a system clock during normal
- * Linux operation should never be attempted, as peripherals that require
- * those clocks will quit working (ie, DRAM).
- *
- * The LPC32xx high level clock tree looks as follows. Clocks marked with
- * an asterisk are always on and cannot be disabled. Clocks marked with
- * an ampersand can only be disabled in CPU suspend mode. Clocks marked
- * with a caret are always on if it is the selected clock for the SYSCLK
- * source. The clock that isn't used for SYSCLK can be enabled and
- * disabled normally.
- *                               32KHz oscillator*
- *                               /      |      \
- *                             RTC*   PLL397^ TOUCH
- *                                     /
- *               Main oscillator^     /
- *                   |        \      /
- *                   |         SYSCLK&
- *                   |            \
- *                   |             \
- *                USB_PLL       HCLK_PLL&
- *                   |           |    |
- *            USB host/device  PCLK&  |
- *                               |    |
- *                             Peripherals
- *
- * The CPU and chip bus rates are derived from the HCLK PLL, which can
- * generate various clock rates up to 266MHz and beyond. The internal bus
- * rates (PCLK and HCLK) are generated from dividers based on the HCLK
- * PLL rate. HCLK can be a ratio of 1:1, 1:2, or 1:4 or HCLK PLL rate,
- * while PCLK can be 1:1 to 1:32 of HCLK PLL rate. Most peripherals high
- * level clocks are based on either HCLK or PCLK, but have their own
- * dividers as part of the IP itself. Because of this, the system clock
- * rates should not be changed.
- *
- * The HCLK PLL is clocked from SYSCLK, which can be derived from the
- * main oscillator or PLL397. PLL397 generates a rate that is 397 times
- * the 32KHz oscillator rate. The main oscillator runs at the selected
- * oscillator/crystal rate on the mosc_in pin of the LPC32xx. This rate
- * is normally 13MHz, but depends on the selection of external crystals
- * or oscillators. If USB operation is required, the main oscillator must
- * be used in the system.
- *
- * Switching SYSCLK between sources during normal Linux operation is not
- * supported. SYSCLK is preset in the bootloader. Because of the
- * complexities of clock management during clock frequency changes,
- * there are some limitations to the clock driver explained below:
- * - The PLL397 and main oscillator can be enabled and disabled by the
- *   clk_enable() and clk_disable() functions unless SYSCLK is based
- *   on that clock. This allows the other oscillator that isn't driving
- *   the HCLK PLL to be used as another system clock that can be routed
- *   to an external pin.
- * - The muxed SYSCLK input and HCLK_PLL rate cannot be changed with
- *   this driver.
- * - HCLK and PCLK rates cannot be changed as part of this driver.
- * - Most peripherals have their own dividers are part of the peripheral
- *   block. Changing SYSCLK, HCLK PLL, HCLK, or PCLK sources or rates
- *   will also impact the individual peripheral rates.

- * In addition to the individual control of the communication

- * communication processor.
- *
- * Buffer descriptors must be allocated from the dual ported memory
- * space.  The allocator for that is here.  When the communication
- * process is reset, we reclaim the memory available.  There is
- * currently no deallocator for this memory.
- * The amount of space available is platform dependent.  On the
- * MBX, the EPPC software loads additional microcode into the
- * communication processor, and uses some of the DP ram for this
- * purpose.  Current, the first 512 bytes and the last 256 bytes of
- * memory are used.  Right now I am conservative and only use the
- * memory that can never be used for microcode.  If there are
- * applications that require more DP ram, we can expand the boundaries
- * but then we have to be careful of any downloaded microcode.

+ * parameters.
+ *
+ * NOTE: For the Core domain events, rather than making domain a required
+ *	 parameter we could default it to PHYS_CORE and allowe users to
+ *	 override the domain to one of the VCPU domains.
+ *
+ *	 However, this can make the interface a little inconsistent.
+ *
+ *	 If we set domain=2 (PHYS_CHIP) and allow user to override this field
+ *	 the user may be tempted to also modify the "offset=x" field in which
+ *	 can lead to confusing usage. Consider the HPM_PCYC (offset=0x18) and
+ *	 HPM_INST (offset=0x20) events. With:
+ *
+ *		perf stat -e hv_24x7/HPM_PCYC,offset=0x20/
+ *
+ *	we end up monitoring HPM_INST, while the command line has HPM_PCYC.
+ *
+ *	By not assigning a default value to the domain for the Core events,
+ *	we can have simple guidelines:
+ *
+ *		- Specifying values for parameters with "=?" is required.
+ *
+ *		- Specifying (i.e overriding) values for other parameters
+ *		  is undefined.

  * 0x30-0x3f	debug traps used by the kernel.
  * 0x40-0xff	Not supported by all parts, so left unhandled.
  *
+ * For making system calls, any trap number in the range for the
+ * given cpu model may be used, but the unified trap number 0x1f is
+ * preferred for compatibility with all models.
+ *
+ * The low bits of the trap number were once documented as matching

+ * This code also handles delegating other traps to the BIOS/gdb stub.

  * Note: When we're first called, the TRA value must be shifted
  * right 2 bits in order to get the value that was used as the "trapa"
  * argument.

+ * STARTED/STOPPING/STOPPED; deal with pmu::start(), pmu::stop() state but are
+ * complicated by the fact that the IBS hardware can send late NMIs (ie. after
+ * we've cleared the EN bit).
+ *
+ * In order to consume these late NMIs we have the STOPPED state, any NMI that
+ * happens after we've cleared the EN state will clear this bit and report the
+ * NMI handled (this is fundamentally racy in the face or multiple NMI sources,
+ * someone else can consume our BIT and our NMI will go unhandled).
+ *
+ * And since we cannot set/clear this separate bit together with the EN bit,
+ * there are races; if we cleared STARTED early, an NMI could land in
+ * between clearing STARTED and clearing the EN bit (in fact multiple NMIs
+ * could happen if the period is small enough), and consume our STOPPED bit
+ * and trigger streams of unhandled NMIs.
+ *
+ * If, however, we clear STARTED late, an NMI can hit between clearing the
+ * EN bit and clearing STARTED, still see STARTED set and process the event.
+ * If this event will have the VALID bit clear, we bail properly, but this
+ * is not a given. With VALID set we can end up calling pmu::stop() again
+ * (the throttle logic) and trigger the WARNs in there.
+ *
+ * So what we do is set STOPPING before clearing EN to avoid the pmu::stop()
+ * nesting, and clear STARTED late, so that we have a well defined state over
+ * the clearing of the EN bit.

+* permission_fault based on two bits of PKRU, on some machine state (CR4,

+* - PK is always zero if RSVD=1 (reserved bit set) or F=1 (instruction fetch)
+* - PK is always zero if U=0 in the page tables
+* - PKRU.WD is ignored if CR0.WP=0 and the access is a supervisor access.
+*
+* The PKRU bitmask caches the result of these four conditions.  The error
+* code (minus the P bit) and the page table's U bit form an index into the
+* PKRU bitmask.  Two bits of the PKRU bitmask are then extracted and ANDed
+* with the two bits of the PKRU register corresponding to the protection key.

+ * DOC: file operations
+ *
+ * Drivers must define the file operations structure that forms the DRM
+ * userspace API entry point, even though most of those operations are
+ * implemented in the DRM core. The mandatory functions are drm_open(),
+ * drm_read(), drm_ioctl() and drm_compat_ioctl if CONFIG_COMPAT is enabled.
+ * Drivers which implement private ioctls that require 32/64 bit compatibility
+ * support must provided their onw .compat_ioctl() handler that processes
+ * private ioctls and calls drm_compat_ioctl() for core ioctls.
+ *
+ * In addition drm_read() and drm_poll() provide support for DRM events. DRM
+ * events are a generic and extensible means to send asynchronous events to
+ * userspace through the file descriptor. They are used to send vblank event and
+ * page flip completions by the KMS API. But drivers can also use it for their
+ * own needs, e.g. to signal completion of rendering.
+ *
+ * The memory mapping implementation will vary depending on how the driver
+ * manages memory. Legacy drivers will use the deprecated drm_legacy_mmap()
+ * function, modern drivers should use one of the provided memory-manager
+ * specific implementations. For GEM-based drivers this is drm_gem_mmap().
+ *
+ * No other file operations are supported by the DRM userspace API. Overall the
+ * following is an example #file_operations structure:

+/**
+ * DOC: Video BIOS Table (VBT)
+ *
+ * The Video BIOS Table, or VBT, provides platform and board specific
+ * configuration information to the driver that is not discoverable or available
+ * through other means. The configuration is mostly related to display
+ * hardware. The VBT is available via the ACPI OpRegion or, on older systems, in
+ * the PCI ROM.
+ *
+ * The VBT consists of a VBT Header (defined as &struct vbt_header), a BDB
+ * Header (&struct bdb_header), and a number of BIOS Data Blocks (BDB) that
+ * contain the actual configuration information. The VBT Header, and thus the
+ * VBT, begins with "$VBT" signature. The VBT Header contains the offset of the
+ * BDB Header. The data blocks are concatenated after the BDB Header. The data
+ * blocks have a 1-byte Block ID, 2-byte Block Size, and Block Size bytes of
+ * data. (Block 53, the MIPI Sequence Block is an exception.)
+ *
+ * The driver parses the VBT during load. The relevant information is stored in
+ * driver private data for ease of use, and the actual VBT is not read after
+ * that.

+ * Secure boot is the process by which NVIDIA-signed firmware is loaded into
+ * some of the falcons of a GPU. For production devices this is the only way
+ * for the firmware to access useful (but sensitive) registers.
+ *
+ * A Falcon microprocessor supporting advanced security modes can run in one of
+ * three modes:
+ *
+ * - Non-secure (NS). In this mode, functionality is similar to Falcon
+ *   architectures before security modes were introduced (pre-Maxwell), but
+ *   capability is restricted. In particular, certain registers may be
+ *   inaccessible for reads and/or writes, and physical memory access may be
+ *   disabled (on certain Falcon instances). This is the only possible mode that
+ *   can be used if you don't have microcode cryptographically signed by NVIDIA.
+ *
+ * - Heavy Secure (HS). In this mode, the microprocessor is a black box - it's
+ *   not possible to read or write any Falcon internal state or Falcon registers
+ *   from outside the Falcon (for example, from the host system). The only way
+ *   to enable this mode is by loading microcode that has been signed by NVIDIA.
+ *   (The loading process involves tagging the IMEM block as secure, writing the
+ *   signature into a Falcon register, and starting execution. The hardware will
+ *   validate the signature, and if valid, grant HS privileges.)
+ *
+ * - Light Secure (LS). In this mode, the microprocessor has more privileges
+ *   than NS but fewer than HS. Some of the microprocessor state is visible to
+ *   host software to ease debugging. The only way to enable this mode is by HS
+ *   microcode enabling LS mode. Some privileges available to HS mode are not
+ *   available here. LS mode is introduced in GM20x.
+ *
+ * Secure boot consists in temporarily switching a HS-capable falcon (typically
+ * PMU) into HS mode in order to validate the LS firmwares of managed falcons,
+ * load them, and switch managed falcons into LS mode. Once secure boot
+ * completes, no falcon remains in HS mode.
+ *
+ * Secure boot requires a write-protected memory region (WPR) which can only be
+ * written by the secure falcon. On dGPU, the driver sets up the WPR region in
+ * video memory. On Tegra, it is set up by the bootloader and its location and
+ * size written into memory controller registers.
+ *
+ * The secure boot process takes place as follows:
+ *
+ * 1) A LS blob is constructed that contains all the LS firmwares we want to
+ *    load, along with their signatures and bootloaders.
+ *
+ * 2) A HS blob (also called ACR) is created that contains the signed HS
+ *    firmware in charge of loading the LS firmwares into their respective
+ *    falcons.
+ *
+ * 3) The HS blob is loaded (via its own bootloader) and executed on the
+ *    HS-capable falcon. It authenticates itself, switches the secure falcon to
+ *    HS mode and setup the WPR region around the LS blob (dGPU) or copies the
+ *    LS blob into the WPR region (Tegra).
+ *
+ * 4) The LS blob is now secure from all external tampering. The HS falcon
+ *    checks the signatures of the LS firmwares and, if valid, switches the
+ *    managed falcons to LS mode and makes them ready to run the LS firmware.
+ *
+ * 5) The managed falcons remain in LS mode and can be started.

- * Atomic hardware plane allocator
- *
- * The hardware plane allocator is solely based on the atomic plane states

- * The core idea is to avoid using a free planes bitmask that would need to be
- * shared between check and commit handlers with a collective knowledge based on
- * the allocated hardware plane(s) for each KMS plane. The allocator then loops
- * over all plane states to compute the free planes bitmask, allocates hardware
- * planes based on that bitmask, and stores the result back in the plane states.
- *
- * For this to work we need to access the current state of planes not touched by
- * the atomic update. To ensure that it won't be modified, we need to lock all
- * planes using drm_atomic_get_plane_state(). This effectively serializes atomic
- * updates from .atomic_check() up to completion (when swapping the states if
- * the check step has succeeded) or rollback (when freeing the states if the

+ * Atomic hardware plane allocator
+ *
+ * The hardware plane allocator is solely based on the atomic plane states
+ * without keeping any external state to avoid races between .atomic_check()
+ * and .atomic_commit().
+ *
+ * The core idea is to avoid using a free planes bitmask that would need to be
+ * shared between check and commit handlers with a collective knowledge based on
+ * the allocated hardware plane(s) for each KMS plane. The allocator then loops
+ * over all plane states to compute the free planes bitmask, allocates hardware
+ * planes based on that bitmask, and stores the result back in the plane states.
+ *
+ * For this to work we need to access the current state of planes not touched by
+ * the atomic update. To ensure that it won't be modified, we need to lock all
+ * planes using drm_atomic_get_plane_state(). This effectively serializes atomic
+ * updates from .atomic_check() up to completion (when swapping the states if
+ * the check step has succeeded) or rollback (when freeing the states if the
+ * check step has failed).
+ *
+ * Allocation is performed in the .atomic_check() handler and applied
+ * automatically when the core swaps the old and new states.

+ * Data transmission timing:
+ * Data bits are encoded as pulse length (high time) on the data line.
+ * 0-bit: 22-30uS -- typically 26uS (AM2302)
+ * 1-bit: 68-75uS -- typically 70uS (AM2302)
+ * The acutal timings also depend on the properties of the cable, with
+ * longer cables typically making pulses shorter.
+ *
+ * Our decoding depends on the time resolution of the system:
+ * timeres > 34uS ... don't know what a 1-tick pulse is
+ * 34uS > timeres > 30uS ... no problem (30kHz and 32kHz clocks)
+ * 30uS > timeres > 23uS ... don't know what a 2-tick pulse is
+ * timeres < 23uS ... no problem
+ *
+ * Luckily clocks in the 33-44kHz range are quite uncommon, so we can
+ * support most systems if the threshold for decoding a pulse as 1-bit
+ * is chosen carefully. If somebody really wants to support clocks around
+ * 40kHz, where this driver is most unreliable, there are two options.
+ * a) select an implementation using busy loop polling on those systems
+ * b) use the checksum to do some probabilistic decoding
