+<title>History</title>
+
+<para>The first API for DVB cards we used at Convergence in late 1999
+was an extension of the Video4Linux API which was primarily developed
+for frame grabber cards. As such it was not really well suited to be
+used for DVB cards and their new features like recording MPEG streams
+and filtering several section and PES data streams at the same time.
+</para>
+
+<para>In early 2000, we were approached by Nokia with a proposal for a
+new standard Linux DVB API. As a commitment to the development of
+terminals based on open standards, Nokia and Convergence made it
+available to all Linux developers and published it on
+<ulink url="http://www.linuxtv.org/" /> in September 2000.
+Convergence is the maintainer of the Linux DVB API. Together with the
+LinuxTV community (i.e. you, the reader of this document), the Linux DVB
+API will be constantly reviewed and improved. With the Linux driver for
+the Siemens/Hauppauge DVB PCI card Convergence provides a first
+implementation of the Linux DVB API.</para>

+<para>A DVB PCI card or DVB set-top-box (STB) usually consists of the
+following main hardware components: </para>
+
+<itemizedlist>
+ <listitem>
+
+<para>Frontend consisting of tuner and DVB demodulator</para>
+
+<para>Here the raw signal reaches the DVB hardware from a satellite dish
+or antenna or directly from cable. The frontend down-converts and
+demodulates this signal into an MPEG transport stream (TS). In case of a
+satellite frontend, this includes a facility for satellite equipment
+control (SEC), which allows control of LNB polarization, multi feed
+switches or dish rotors.</para>
+
+</listitem>
+ <listitem>
+
+<para>Conditional Access (CA) hardware like CI adapters and smartcard slots
+</para>
+
+<para>The complete TS is passed through the CA hardware. Programs to
+which the user has access (controlled by the smart card) are decoded in
+real time and re-inserted into the TS.</para>
+
+</listitem>
+ <listitem>
+ <para>Demultiplexer which filters the incoming DVB stream</para>
+
+<para>The demultiplexer splits the TS into its components like audio and
+video streams. Besides usually several of such audio and video streams
+it also contains data streams with information about the programs
+offered in this or other streams of the same provider.</para>
+
+</listitem>
+<listitem>
+
+<para>MPEG2 audio and video decoder</para>
+
+<para>The main targets of the demultiplexer are the MPEG2 audio and
+video decoders. After decoding they pass on the uncompressed audio and
+video to the computer screen or (through a PAL/NTSC encoder) to a TV
+set.</para>
+
+
+</listitem>
+</itemizedlist>
+
+<para><xref linkend="stb_components" /> shows a crude schematic of the control and data flow
+between those components.</para>
+
+<para>On a DVB PCI card not all of these have to be present since some
+functionality can be provided by the main CPU of the PC (e.g. MPEG
+picture and sound decoding) or is not needed (e.g. for data-only uses
+like &#8220;internet over satellite&#8221;). Also not every card or STB
+provides conditional access hardware.</para>
+
+</section>
+
+<section id="dvb_devices">
+<title>Linux DVB Devices</title>
+
+<para>The Linux DVB API lets you control these hardware components
+through currently six Unix-style character devices for video, audio,
+frontend, demux, CA and IP-over-DVB networking. The video and audio
+devices control the MPEG2 decoder hardware, the frontend device the
+tuner and the DVB demodulator. The demux device gives you control over
+the PES and section filters of the hardware. If the hardware does not
+support filtering these filters can be implemented in software. Finally,
+the CA device controls all the conditional access capabilities of the
+hardware. It can depend on the individual security requirements of the
+platform, if and how many of the CA functions are made available to the
+application through this device.</para>
+
+<para>All devices can be found in the <emphasis role="tt">/dev</emphasis>
+tree under <emphasis role="tt">/dev/dvb</emphasis>. The individual devices
+are called:</para>

+ <para>This section describes shortly what are the possible parameters in the Linux

+ demodulator:</para>
+
+ <para>This ISDB-T/ISDB-Tsb API extension should reflect all information
+ needed to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible
+ that some very sophisticated devices won't need certain parameters to
+ tune.</para>
+
+ <para>The information given here should help application writers to know how
+ to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.</para>
+
+ <para>The details given here about ISDB-T and ISDB-Tsb are just enough to
+ basically show the dependencies between the needed parameter values,
+ but surely some information is left out. For more detailed information
+ see the following documents:</para>

+ Television Broadcasting" and</para>

+ <para>In order to read this document one has to have some knowledge the
+ channel structure in ISDB-T and ISDB-Tsb. I.e. it has to be known to
+ the reader that an ISDB-T channel consists of 13 segments, that it can

+<title>Demux API</title>
+<para>The demux API should be implemented for each demux in the system. It is used to select
+the TS source of a demux and to manage the demux resources. When the demux
+client allocates a resource via the demux API, it receives a pointer to the API of that
+resource.
+</para>
+<para>Each demux receives its TS input from a DVB front-end or from memory, as set via the
+demux API. In a system with more than one front-end, the API can be used to select one of
+the DVB front-ends as a TS source for a demux, unless this is fixed in the HW platform. The
+demux API only controls front-ends regarding their connections with demuxes; the APIs
+used to set the other front-end parameters, such as tuning, are not defined in this
+document.
+</para>
+<para>The functions that implement the abstract interface demux should be defined static or
+module private and registered to the Demux Directory for external access. It is not necessary
+to implement every function in the demux_t struct, however (for example, a demux interface
+might support Section filtering, but not TS or PES filtering). The API client is expected to
+check the value of any function pointer before calling the function: the value of NULL means
+&#8220;function not available&#8221;.
+</para>
+<para>Whenever the functions of the demux API modify shared data, the possibilities of lost
+update and race condition problems should be addressed, e.g. by protecting parts of code with
+mutexes. This is especially important on multi-processor hosts.
+</para>
+<para>Note that functions called from a bottom half context must not sleep, at least in the 2.2.x
+kernels. Even a simple memory allocation can result in a kernel thread being put to sleep if
+swapping is needed. For example, the Linux kernel calls the functions of a network device
+interface from a bottom half context. Thus, if a demux API function is called from network
+device code, the function must not sleep.

+from the demux code.
+</para>
+<para>The function pointers of this abstract interface are not packed into a structure as in the

+callback functions for receiving TS packets and no callbacks for PES packets or

+<para>The functions that implement the callback API need not be re-entrant: when a demux
+driver calls one of these functions, the driver is not allowed to call the function again before
+the original call returns. If a callback is triggered by a hardware interrupt, it is recommended
+to use the Linux &#8220;bottom half&#8221; mechanism or start a tasklet instead of making the callback

+ video and radio straming devices, including video cameras,
+ analog and digital TV receiver cards, AM/FM receiver cards,
+ streaming capture devices.</para>
+ <para>It is divided into three parts.</para>
+ <para>The first part covers radio, capture,
+ cameras and analog TV devices.</para>
+ <para>The second part covers the
+ API used for digital TV and Internet reception via one of the
+ several digital tv standards. While it is called as DVB API,
+ in fact it covers several different video standards including
+ DVB-T, DVB-S, DVB-C and ATSC. The API is currently being updated
+ to documment support also for DVB-S2, ISDB-T and ISDB-S.</para>
+ <para>The third part covers other API's used by all media infrastructure devices</para>
+ <para>For additional information and for the latest development code,

+ <section>
+ <title>Device Naming</title>
+
+ <para>V4L2 drivers are implemented as kernel modules, loaded
+manually by the system administrator or automatically when a device is
+first opened. The driver modules plug into the "videodev" kernel
+module. It provides helper functions and a common application
+interface specified in this document.</para>
+
+ <para>Each driver thus loaded registers one or more device nodes
+with major number 81 and a minor number between 0 and 255. Assigning
+minor numbers to V4L2 devices is entirely up to the system administrator,
+this is primarily intended to solve conflicts between devices.<footnote>
+ <para>Access permissions are associated with character
+device special files, hence we must ensure device numbers cannot
+change with the module load order. To this end minor numbers are no
+longer automatically assigned by the "videodev" module as in V4L but
+requested by the driver. The defaults will suffice for most people
+unless two drivers compete for the same minor numbers.</para>
+ </footnote> The module options to select minor numbers are named
+after the device special file with a "_nr" suffix. For example "video_nr"
+for <filename>/dev/video</filename> video capture devices. The number is
+an offset to the base minor number associated with the device type.
+<footnote>
+ <para>In earlier versions of the V4L2 API the module options
+where named after the device special file with a "unit_" prefix, expressing
+the minor number itself, not an offset. Rationale for this change is unknown.
+Lastly the naming and semantics are just a convention among driver writers,
+the point to note is that minor numbers are not supposed to be hardcoded
+into drivers.</para>
+ </footnote> When the driver supports multiple devices of the same
+type more than one minor number can be assigned, separated by commas:
+<informalexample>
+ <screen>
+&gt; insmod mydriver.o video_nr=0,1 radio_nr=0,1</screen>
+ </informalexample></para>
+
+ <para>In <filename>/etc/modules.conf</filename> this may be
+written as: <informalexample>
+ <screen>
+alias char-major-81-0 mydriver
+alias char-major-81-1 mydriver
+alias char-major-81-64 mydriver <co id="alias" />
+options mydriver video_nr=0,1 radio_nr=0,1 <co id="options" />
+ </screen>

+registered. <!-- Blessed by Linus Torvalds on
+linux-kernel@vger.kernel.org, 2002-11-20. --></para>
+
+ <para>By convention system administrators create various
+character device special files with these major and minor numbers in
+the <filename>/dev</filename> directory. The names recomended for the
+different V4L2 device types are listed in <xref linkend="devices" />.
+</para>
+
+ <para>The creation of character special files (with
+<application>mknod</application>) is a privileged operation and
+devices cannot be opened by major and minor number. That means
+applications cannot <emphasis>reliable</emphasis> scan for loaded or
+installed drivers. The user must enter a device name, or the
+application can try the conventional device names.</para>
+
+ <para>Under the device filesystem (devfs) the minor number
+options are ignored. V4L2 drivers (or by proxy the "videodev" module)
+automatically create the required device files in the
+<filename>/dev/v4l</filename> directory using the conventional device
+names above.</para>
+ </section>
+
+ <section id="related">
+ <title>Related Devices</title>
+
+ <para>Devices can support several related functions. For example
+video capturing, video overlay and VBI capturing are related because
+these functions share, amongst other, the same video input and tuner
+frequency. V4L and earlier versions of V4L2 used the same device name
+and minor number for video capturing and overlay, but different ones
+for VBI. Experience showed this approach has several problems<footnote>
+ <para>Given a device file name one cannot reliable find
+related devices. For once names are arbitrary and in a system with
+multiple devices, where only some support VBI capturing, a
+<filename>/dev/video2</filename> is not necessarily related to
+<filename>/dev/vbi2</filename>. The V4L
+<constant>VIDIOCGUNIT</constant> ioctl would require a search for a
+device file with a particular major and minor number.</para>
+ </footnote>, and to make things worse the V4L videodev module
+used to prohibit multiple opens of a device.</para>
+
+ <para>As a remedy the present version of the V4L2 API relaxed the
+concept of device types with specific names and minor numbers. For
+compatibility with old applications drivers must still register different
+minor numbers to assign a default function to the device. But if related
+functions are supported by the driver they must be available under all
+registered minor numbers. The desired function can be selected after
+opening the device as described in <xref linkend="devices" />.</para>
+
+ <para>Imagine a driver supporting video capturing, video
+overlay, raw VBI capturing, and FM radio reception. It registers three
+devices with minor number 0, 64 and 224 (this numbering scheme is
+inherited from the V4L API). Regardless if
+<filename>/dev/video</filename> (81, 0) or
+<filename>/dev/vbi</filename> (81, 224) is opened the application can
+select any one of the video capturing, overlay or VBI capturing
+functions. Without programming (e.&nbsp;g. reading from the device
+with <application>dd</application> or <application>cat</application>)
+<filename>/dev/video</filename> captures video images, while
+<filename>/dev/vbi</filename> captures raw VBI data.
+<filename>/dev/radio</filename> (81, 64) is invariable a radio device,
+unrelated to the video functions. Being unrelated does not imply the
+devices can be used at the same time, however. The &func-open;
+function may very well return an &EBUSY;.</para>
+
+ <para>Besides video input or output the hardware may also
+support audio sampling or playback. If so, these functions are
+implemented as OSS or ALSA PCM devices and eventually OSS or ALSA
+audio mixer. The V4L2 API makes no provisions yet to find these
+related devices. If you have an idea please write to the linux-media
+mailing list: &v4l-ml;.</para>
+ </section>
+
+ <section>
+ <title>Multiple Opens</title>
+
+ <para>In general, V4L2 devices can be opened more than once.
+When this is supported by the driver, users can for example start a
+"panel" application to change controls like brightness or audio
+volume, while another application captures video and audio. In other words, panel
+applications are comparable to an OSS or ALSA audio mixer application.
+When a device supports multiple functions like capturing and overlay
+<emphasis>simultaneously</emphasis>, multiple opens allow concurrent
+use of the device by forked processes or specialized applications.</para>
+
+ <para>Multiple opens are optional, although drivers should
+permit at least concurrent accesses without data exchange, &ie; panel
+applications. This implies &func-open; can return an &EBUSY; when the
+device is already in use, as well as &func-ioctl; functions initiating
+data exchange (namely the &VIDIOC-S-FMT; ioctl), and the &func-read;
+and &func-write; functions.</para>
+
+ <para>Mere opening a V4L2 device does not grant exclusive
+access.<footnote>
+ <para>Drivers could recognize the
+<constant>O_EXCL</constant> open flag. Presently this is not required,
+so applications cannot know if it really works.</para>
+ </footnote> Initiating data exchange however assigns the right
+to read or write the requested type of data, and to change related
+properties, to this file descriptor. Applications can request
+additional access privileges using the priority mechanism described in
+<xref linkend="app-pri" />.</para>
+ </section>
+
+ <section>
+ <title>Shared Data Streams</title>
+
+ <para>V4L2 drivers should not support multiple applications
+reading or writing the same data stream on a device by copying
+buffers, time multiplexing or similar means. This is better handled by
+a proxy application in user space. When the driver supports stream
+sharing anyway it must be implemented transparently. The V4L2 API does
+not specify how conflicts are solved. <!-- For example O_EXCL when the
+application does not want to be preempted, PROT_READ mmapped buffers
+which can be mapped twice, what happens when image formats do not
+match etc.--></para>
+ </section>
+
+ <section>
+ <title>Functions</title>
+
+ <para>To open and close V4L2 devices applications use the
+&func-open; and &func-close; function, respectively. Devices are
+programmed using the &func-ioctl; function as explained in the
+following sections.</para>
+ </section>
+ </section>
+
+ <section id="querycap">
+ <title>Querying Capabilities</title>
+
+ <para>Because V4L2 covers a wide variety of devices not all
+aspects of the API are equally applicable to all types of devices.
+Furthermore devices of the same type have different capabilities and
+this specification permits the omission of a few complicated and less
+important parts of the API.</para>
+
+ <para>The &VIDIOC-QUERYCAP; ioctl is available to check if the kernel
+device is compatible with this specification, and to query the <link
+linkend="devices">functions</link> and <link linkend="io">I/O
+methods</link> supported by the device. Other features can be queried
+by calling the respective ioctl, for example &VIDIOC-ENUMINPUT;
+to learn about the number, types and names of video connectors on the
+device. Although abstraction is a major objective of this API, the
+ioctl also allows driver specific applications to reliable identify
+the driver.</para>
+
+ <para>All V4L2 drivers must support
+<constant>VIDIOC_QUERYCAP</constant>. Applications should always call
+this ioctl after opening the device.</para>
+ </section>
+
+ <section id="app-pri">
+ <title>Application Priority</title>
+
+ <para>When multiple applications share a device it may be
+desirable to assign them different priorities. Contrary to the
+traditional "rm -rf /" school of thought a video recording application
+could for example block other applications from changing video
+controls or switching the current TV channel. Another objective is to
+permit low priority applications working in background, which can be
+preempted by user controlled applications and automatically regain
+control of the device at a later time.</para>
+
+ <para>Since these features cannot be implemented entirely in user
+space V4L2 defines the &VIDIOC-G-PRIORITY; and &VIDIOC-S-PRIORITY;
+ioctls to request and query the access priority associate with a file
+descriptor. Opening a device assigns a medium priority, compatible
+with earlier versions of V4L2 and drivers not supporting these ioctls.
+Applications requiring a different priority will usually call
+<constant>VIDIOC_S_PRIORITY</constant> after verifying the device with
+the &VIDIOC-QUERYCAP; ioctl.</para>
+
+ <para>Ioctls changing driver properties, such as &VIDIOC-S-INPUT;,
+return an &EBUSY; after another application obtained higher priority.
+An event mechanism to notify applications about asynchronous property
+changes has been proposed but not added yet.</para>

+ <title>Data Format Negotiation</title>
+
+ <para>Different devices exchange different kinds of data with
+applications, for example video images, raw or sliced VBI data, RDS
+datagrams. Even within one kind many different formats are possible,
+in particular an abundance of image formats. Although drivers must
+provide a default and the selection persists across closing and
+reopening a device, applications should always negotiate a data format
+before engaging in data exchange. Negotiation means the application
+asks for a particular format and the driver selects and reports the
+best the hardware can do to satisfy the request. Of course
+applications can also just query the current selection.</para>
+
+ <para>A single mechanism exists to negotiate all data formats
+using the aggregate &v4l2-format; and the &VIDIOC-G-FMT; and
+&VIDIOC-S-FMT; ioctls. Additionally the &VIDIOC-TRY-FMT; ioctl can be
+used to examine what the hardware <emphasis>could</emphasis> do,
+without actually selecting a new data format. The data formats
+supported by the V4L2 API are covered in the respective device section
+in <xref linkend="devices" />. For a closer look at image formats see
+<xref linkend="pixfmt" />.</para>
+
+ <para>The <constant>VIDIOC_S_FMT</constant> ioctl is a major
+turning-point in the initialization sequence. Prior to this point
+multiple panel applications can access the same device concurrently to
+select the current input, change controls or modify other properties.
+The first <constant>VIDIOC_S_FMT</constant> assigns a logical stream
+(video data, VBI data etc.) exclusively to one file descriptor.</para>
+
+ <para>Exclusive means no other application, more precisely no
+other file descriptor, can grab this stream or change device
+properties inconsistent with the negotiated parameters. A video
+standard change for example, when the new standard uses a different
+number of scan lines, can invalidate the selected image format.
+Therefore only the file descriptor owning the stream can make
+invalidating changes. Accordingly multiple file descriptors which
+grabbed different logical streams prevent each other from interfering
+with their settings. When for example video overlay is about to start
+or already in progress, simultaneous video capturing may be restricted
+to the same cropping and image size.</para>
+
+ <para>When applications omit the
+<constant>VIDIOC_S_FMT</constant> ioctl its locking side effects are
+implied by the next step, the selection of an I/O method with the
+&VIDIOC-REQBUFS; ioctl or implicit with the first &func-read; or
+&func-write; call.</para>
+
+ <para>Generally only one logical stream can be assigned to a
+file descriptor, the exception being drivers permitting simultaneous
+video capturing and overlay using the same file descriptor for
+compatibility with V4L and earlier versions of V4L2. Switching the
+logical stream or returning into "panel mode" is possible by closing
+and reopening the device. Drivers <emphasis>may</emphasis> support a
+switch using <constant>VIDIOC_S_FMT</constant>.</para>
+
+ <para>All drivers exchanging data with
+applications must support the <constant>VIDIOC_G_FMT</constant> and
+<constant>VIDIOC_S_FMT</constant> ioctl. Implementation of the
+<constant>VIDIOC_TRY_FMT</constant> is highly recommended but

+using the same coordinate system as &v4l2-cropcap;. Applications can

+ <section>
+ <title>Scaling Adjustments</title>
+
+ <para>Video hardware can have various cropping, insertion and
+scaling limitations. It may only scale up or down, support only
+discrete scaling factors, or have different scaling abilities in
+horizontal and vertical direction. Also it may not support scaling at
+all. At the same time the &v4l2-crop; rectangle may have to be
+aligned, and both the source and target rectangles may have arbitrary
+upper and lower size limits. In particular the maximum
+<structfield>width</structfield> and <structfield>height</structfield>
+in &v4l2-crop; may be smaller than the
+&v4l2-cropcap;.<structfield>bounds</structfield> area. Therefore, as
+usual, drivers are expected to adjust the requested parameters and
+return the actual values selected.</para>
+
+ <para>Applications can change the source or the target rectangle
+first, as they may prefer a particular image size or a certain area in
+the video signal. If the driver has to adjust both to satisfy hardware
+limitations, the last requested rectangle shall take priority, and the
+driver should preferably adjust the opposite one. The &VIDIOC-TRY-FMT;
+ioctl however shall not change the driver state and therefore only
+adjust the requested rectangle.</para>
+
+ <para>Suppose scaling on a video capture device is restricted to
+a factor 1:1 or 2:1 in either direction and the target image size must
+be a multiple of 16&nbsp;&times;&nbsp;16 pixels. The source cropping
+rectangle is set to defaults, which are also the upper limit in this
+example, of 640&nbsp;&times;&nbsp;400 pixels at offset 0,&nbsp;0. An
+application requests an image size of 300&nbsp;&times;&nbsp;225
+pixels, assuming video will be scaled down from the "full picture"
+accordingly. The driver sets the image size to the closest possible
+values 304&nbsp;&times;&nbsp;224, then chooses the cropping rectangle
+closest to the requested size, that is 608&nbsp;&times;&nbsp;224
+(224&nbsp;&times;&nbsp;2:1 would exceed the limit 400). The offset
+0,&nbsp;0 is still valid, thus unmodified. Given the default cropping
+rectangle reported by <constant>VIDIOC_CROPCAP</constant> the
+application can easily propose another offset to center the cropping
+rectangle.</para>
+
+ <para>Now the application may insist on covering an area using a
+picture aspect ratio closer to the original request, so it asks for a
+cropping rectangle of 608&nbsp;&times;&nbsp;456 pixels. The present
+scaling factors limit cropping to 640&nbsp;&times;&nbsp;384, so the
+driver returns the cropping size 608&nbsp;&times;&nbsp;384 and adjusts
+the image size to closest possible 304&nbsp;&times;&nbsp;192.</para>

+ <title>Changes of the V4L2 API</title>
+
+ <para>Soon after the V4L API was added to the kernel it was
+criticised as too inflexible. In August 1998 Bill Dirks proposed a
+number of improvements and began to work on documentation, example
+drivers and applications. With the help of other volunteers this
+eventually became the V4L2 API, not just an extension but a
+replacement for the V4L API. However it took another four years and
+two stable kernel releases until the new API was finally accepted for
+inclusion into the kernel in its present form.</para>

+signed 64-bit integer. Output devices should not send a buffer out
+until the time in the timestamp field has arrived. I would like to
+follow SGI's lead, and adopt a multimedia timestamping system like
+their UST (Unadjusted System Time). See
+http://reality.sgi.com/cpirazzi_engr/lg/time/intro.html. [This link is
+no longer valid.] UST uses timestamps that are 64-bit signed integers
+(not struct timeval's) and given in nanosecond units. The UST clock
+starts at zero when the system is booted and runs continuously and
+uniformly. It takes a little over 292 years for UST to overflow. There
+is no way to set the UST clock. The regular Linux time-of-day clock
+can be changed periodically, which would cause errors if it were being
+used for timestamping a multimedia stream. A real UST style clock will
+require some support in the kernel that is not there yet. But in
+anticipation, I will change the timestamp field to a 64-bit integer,
+and I will change the v4l2_masterclock_gettime() function (used only
+by drivers) to return a 64-bit integer.</para>

+ <title>V4L2 in Linux 2.5.46, 2002-10</title>
+
+ <para>Around October-November 2002, prior to an announced
+feature freeze of Linux 2.5, the API was revised, drawing from
+experience with V4L2 0.20. This unnamed version was finally merged
+into Linux 2.5.46.</para>
+
+ <orderedlist>
+ <listitem>
+ <para>As specified in <xref linkend="related" />, drivers
+must make related device functions available under all minor device
+numbers.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &func-open; function requires access mode
+<constant>O_RDWR</constant> regardless of the device type. All V4L2
+drivers exchanging data with applications must support the
+<constant>O_NONBLOCK</constant> flag. The <constant>O_NOIO</constant>
+flag, a V4L2 symbol which aliased the meaningless
+<constant>O_TRUNC</constant> to indicate accesses without data
+exchange (panel applications) was dropped. Drivers must stay in "panel
+mode" until the application attempts to initiate a data exchange, see
+<xref linkend="open" />.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &v4l2-capability; changed dramatically. Note that
+also the size of the structure changed, which is encoded in the ioctl
+request code, thus older V4L2 devices will respond with an &EINVAL; to
+the new &VIDIOC-QUERYCAP; ioctl.</para>
+
+ <para>There are new fields to identify the driver, a new RDS
+device function <constant>V4L2_CAP_RDS_CAPTURE</constant>, the
+<constant>V4L2_CAP_AUDIO</constant> flag indicates if the device has
+any audio connectors, another I/O capability
+<constant>V4L2_CAP_ASYNCIO</constant> can be flagged. In response to
+these changes the <structfield>type</structfield> field became a bit
+set and was merged into the <structfield>flags</structfield> field.
+<constant>V4L2_FLAG_TUNER</constant> was renamed to
+<constant>V4L2_CAP_TUNER</constant>,
+<constant>V4L2_CAP_VIDEO_OVERLAY</constant> replaced
+<constant>V4L2_FLAG_PREVIEW</constant> and
+<constant>V4L2_CAP_VBI_CAPTURE</constant> and
+<constant>V4L2_CAP_VBI_OUTPUT</constant> replaced
+<constant>V4L2_FLAG_DATA_SERVICE</constant>.
+<constant>V4L2_FLAG_READ</constant> and
+<constant>V4L2_FLAG_WRITE</constant> were merged into
+<constant>V4L2_CAP_READWRITE</constant>.</para>
+
+ <para>The redundant fields
+<structfield>inputs</structfield>, <structfield>outputs</structfield>
+and <structfield>audios</structfield> were removed. These properties
+can be determined as described in <xref linkend="video" /> and <xref
+linkend="audio" />.</para>
+
+ <para>The somewhat volatile and therefore barely useful
+fields <structfield>maxwidth</structfield>,
+<structfield>maxheight</structfield>,
+<structfield>minwidth</structfield>,
+<structfield>minheight</structfield>,
+<structfield>maxframerate</structfield> were removed. This information
+is available as described in <xref linkend="format" /> and
+<xref linkend="standard" />.</para>
+
+ <para><constant>V4L2_FLAG_SELECT</constant> was removed. We
+believe the select() function is important enough to require support
+of it in all V4L2 drivers exchanging data with applications. The
+redundant <constant>V4L2_FLAG_MONOCHROME</constant> flag was removed,
+this information is available as described in <xref
+ linkend="format" />.</para>
+ </listitem>
+
+ <listitem>
+ <para>In &v4l2-input; the
+<structfield>assoc_audio</structfield> field and the
+<structfield>capability</structfield> field and its only flag
+<constant>V4L2_INPUT_CAP_AUDIO</constant> was replaced by the new
+<structfield>audioset</structfield> field. Instead of linking one
+video input to one audio input this field reports all audio inputs
+this video input combines with.</para>
+
+ <para>New fields are <structfield>tuner</structfield>
+(reversing the former link from tuners to video inputs),
+<structfield>std</structfield> and
+<structfield>status</structfield>.</para>
+
+ <para>Accordingly &v4l2-output; lost its
+<structfield>capability</structfield> and
+<structfield>assoc_audio</structfield> fields.
+<structfield>audioset</structfield>,
+<structfield>modulator</structfield> and
+<structfield>std</structfield> where added instead.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &v4l2-audio; field
+<structfield>audio</structfield> was renamed to
+<structfield>index</structfield>, for consistency with other
+structures. A new capability flag
+<constant>V4L2_AUDCAP_STEREO</constant> was added to indicated if the
+audio input in question supports stereo sound.
+<constant>V4L2_AUDCAP_EFFECTS</constant> and the corresponding
+<constant>V4L2_AUDMODE</constant> flags where removed. This can be
+easily implemented using controls. (However the same applies to AVL
+which is still there.)</para>
+
+ <para>Again for consistency the &v4l2-audioout; field
+<structfield>audio</structfield> was renamed to
+<structfield>index</structfield>.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &v4l2-tuner;
+<structfield>input</structfield> field was replaced by an
+<structfield>index</structfield> field, permitting devices with
+multiple tuners. The link between video inputs and tuners is now
+reversed, inputs point to their tuner. The
+<structfield>std</structfield> substructure became a
+simple set (more about this below) and moved into &v4l2-input;. A
+<structfield>type</structfield> field was added.</para>
+
+ <para>Accordingly in &v4l2-modulator; the
+<structfield>output</structfield> was replaced by an
+<structfield>index</structfield> field.</para>
+
+ <para>In &v4l2-frequency; the
+<structfield>port</structfield> field was replaced by a
+<structfield>tuner</structfield> field containing the respective tuner
+or modulator index number. A tuner <structfield>type</structfield>
+field was added and the <structfield>reserved</structfield> field
+became larger for future extensions (satellite tuners in
+particular).</para>
+ </listitem>
+
+ <listitem>
+ <para>The idea of completely transparent video standards was
+dropped. Experience showed that applications must be able to work with
+video standards beyond presenting the user a menu. Instead of
+enumerating supported standards with an ioctl applications can now
+refer to standards by &v4l2-std-id; and symbols defined in the
+<filename>videodev2.h</filename> header file. For details see <xref
+ linkend="standard" />. The &VIDIOC-G-STD; and
+&VIDIOC-S-STD; now take a pointer to this type as argument.
+&VIDIOC-QUERYSTD; was added to autodetect the received standard, if
+the hardware has this capability. In &v4l2-standard; an
+<structfield>index</structfield> field was added for &VIDIOC-ENUMSTD;.
+A &v4l2-std-id; field named <structfield>id</structfield> was added as
+machine readable identifier, also replacing the
+<structfield>transmission</structfield> field. The misleading
+<structfield>framerate</structfield> field was renamed
+to <structfield>frameperiod</structfield>. The now obsolete
+<structfield>colorstandard</structfield> information, originally
+needed to distguish between variations of standards, were
+removed.</para>
+
+ <para>Struct <structname>v4l2_enumstd</structname> ceased to
+be. &VIDIOC-ENUMSTD; now takes a pointer to a &v4l2-standard;
+directly. The information which standards are supported by a
+particular video input or output moved into &v4l2-input; and
+&v4l2-output; fields named <structfield>std</structfield>,
+respectively.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &v4l2-queryctrl; fields
+<structfield>category</structfield> and
+<structfield>group</structfield> did not catch on and/or were not
+implemented as expected and therefore removed.</para>
+ </listitem>
+
+ <listitem>
+ <para>The &VIDIOC-TRY-FMT; ioctl was added to negotiate data
+formats as with &VIDIOC-S-FMT;, but without the overhead of
+programming the hardware and regardless of I/O in progress.</para>
+
+ <para>In &v4l2-format; the <structfield>fmt</structfield>
+union was extended to contain &v4l2-window;. All image format
+negotiations are now possible with <constant>VIDIOC_G_FMT</constant>,
+<constant>VIDIOC_S_FMT</constant> and
+<constant>VIDIOC_TRY_FMT</constant>; ioctl. The
+<constant>VIDIOC_G_WIN</constant> and
+<constant>VIDIOC_S_WIN</constant> ioctls to prepare for a video
+overlay were removed. The <structfield>type</structfield> field
+changed to type &v4l2-buf-type; and the buffer type names changed as
+follows.<informaltable>

+ <title>X Video Extension</title>
+
+ <para>The X Video Extension (abbreviated XVideo or just Xv) is
+an extension of the X Window system, implemented for example by the
+XFree86 project. Its scope is similar to V4L2, an API to video capture
+and output devices for X clients. Xv allows applications to display
+live video in a window, send window contents to a TV output, and
+capture or output still images in XPixmaps<footnote>
+ <para>This is not implemented in XFree86.</para>
+ </footnote>. With their implementation XFree86 makes the
+extension available across many operating systems and
+architectures.</para>
+
+ <para>Because the driver is embedded into the X server Xv has a
+number of advantages over the V4L2 <link linkend="overlay">video
+overlay interface</link>. The driver can easily determine the overlay
+target, &ie; visible graphics memory or off-screen buffers for a
+destructive overlay. It can program the RAMDAC for a non-destructive
+overlay, scaling or color-keying, or the clipping functions of the
+video capture hardware, always in sync with drawing operations or
+windows moving or changing their stacking order.</para>
+
+ <para>To combine the advantages of Xv and V4L a special Xv
+driver exists in XFree86 and XOrg, just programming any overlay capable
+Video4Linux device it finds. To enable it
+<filename>/etc/X11/XF86Config</filename> must contain these lines:</para>
+ <para><screen>
+Section "Module"
+ Load "v4l"
+EndSection</screen></para>
+
+ <para>As of XFree86 4.2 this driver still supports only V4L
+ioctls, however it should work just fine with all V4L2 devices through
+the V4L2 backward-compatibility layer. Since V4L2 permits multiple
+opens it is possible (if supported by the V4L2 driver) to capture
+video while an X client requested video overlay. Restrictions of
+simultaneous capturing and overlay are discussed in <xref
+ linkend="overlay" /> apply.</para>
+
+ <para>Only marginally related to V4L2, XFree86 extended Xv to
+support hardware YUV to RGB conversion and scaling for faster video
+playback, and added an interface to MPEG-2 decoding hardware. This API
+is useful to display images captured with V4L2 devices.</para>

+ <section>
+ <title>Digital Video</title>
+
+ <para>V4L2 does not support digital terrestrial, cable or

+ <title>User Controls</title>
+
+ <para>Devices typically have a number of user-settable controls
+such as brightness, saturation and so on, which would be presented to
+the user on a graphical user interface. But, different devices
+will have different controls available, and furthermore, the range of
+possible values, and the default value will vary from device to
+device. The control ioctls provide the information and a mechanism to
+create a nice user interface for these controls that will work
+correctly with any device.</para>
+
+ <para>All controls are accessed using an ID value. V4L2 defines
+several IDs for specific purposes. Drivers can also implement their
+own custom controls using <constant>V4L2_CID_PRIVATE_BASE</constant>
+and higher values. The pre-defined control IDs have the prefix
+<constant>V4L2_CID_</constant>, and are listed in <xref
+linkend="control-id" />. The ID is used when querying the attributes of
+a control, and when getting or setting the current value.</para>
+
+ <para>Generally applications should present controls to the user
+without assumptions about their purpose. Each control comes with a
+name string the user is supposed to understand. When the purpose is
+non-intuitive the driver writer should provide a user manual, a user
+interface plug-in or a driver specific panel application. Predefined
+IDs were introduced to change a few controls programmatically, for
+example to mute a device during a channel switch.</para>
+
+ <para>Drivers may enumerate different controls after switching
+the current video input or output, tuner or modulator, or audio input
+or output. Different in the sense of other bounds, another default and
+current value, step size or other menu items. A control with a certain
+<emphasis>custom</emphasis> ID can also change name and
+type.<footnote>
+ <para>It will be more convenient for applications if drivers
+make use of the <constant>V4L2_CTRL_FLAG_DISABLED</constant> flag, but
+that was never required.</para>
+ </footnote> Control values are stored globally, they do not
+change when switching except to stay within the reported bounds. They
+also do not change &eg; when the device is opened or closed, when the
+tuner radio frequency is changed or generally never without
+application request. Since V4L2 specifies no event mechanism, panel
+applications intended to cooperate with other panel applications (be
+they built into a larger application, as a TV viewer) may need to
+regularly poll control values to update their user
+interface.<footnote>
+ <para>Applications could call an ioctl to request events.
+After another process called &VIDIOC-S-CTRL; or another ioctl changing
+shared properties the &func-select; function would indicate
+readability until any ioctl (querying the properties) is
+called.</para>

+ <section>
+ <title>Introduction</title>
+
+ <para>The control mechanism as originally designed was meant
+to be used for user settings (brightness, saturation, etc). However,
+it turned out to be a very useful model for implementing more
+complicated driver APIs where each driver implements only a subset of
+a larger API.</para>
+
+ <para>The MPEG encoding API was the driving force behind
+designing and implementing this extended control mechanism: the MPEG
+standard is quite large and the currently supported hardware MPEG
+encoders each only implement a subset of this standard. Further more,
+many parameters relating to how the video is encoded into an MPEG
+stream are specific to the MPEG encoding chip since the MPEG standard
+only defines the format of the resulting MPEG stream, not how the
+video is actually encoded into that format.</para>
+
+ <para>Unfortunately, the original control API lacked some
+features needed for these new uses and so it was extended into the
+(not terribly originally named) extended control API.</para>
+
+ <para>Even though the MPEG encoding API was the first effort
+to use the Extended Control API, nowadays there are also other classes
+of Extended Controls, such as Camera Controls and FM Transmitter Controls.
+The Extended Controls API as well as all Extended Controls classes are
+described in the following text.</para>
+ </section>
+
+ <section>
+ <title>The Extended Control API</title>
+
+ <para>Three new ioctls are available: &VIDIOC-G-EXT-CTRLS;,
+&VIDIOC-S-EXT-CTRLS; and &VIDIOC-TRY-EXT-CTRLS;. These ioctls act on
+arrays of controls (as opposed to the &VIDIOC-G-CTRL; and
+&VIDIOC-S-CTRL; ioctls that act on a single control). This is needed
+since it is often required to atomically change several controls at
+once.</para>
+
+ <para>Each of the new ioctls expects a pointer to a
+&v4l2-ext-controls;. This structure contains a pointer to the control
+array, a count of the number of controls in that array and a control
+class. Control classes are used to group similar controls into a
+single class. For example, control class
+<constant>V4L2_CTRL_CLASS_USER</constant> contains all user controls
+(&ie; all controls that can also be set using the old
+<constant>VIDIOC_S_CTRL</constant> ioctl). Control class
+<constant>V4L2_CTRL_CLASS_MPEG</constant> contains all controls
+relating to MPEG encoding, etc.</para>
+
+ <para>All controls in the control array must belong to the
+specified control class. An error is returned if this is not the
+case.</para>
+
+ <para>It is also possible to use an empty control array (count
+== 0) to check whether the specified control class is
+supported.</para>
+
+ <para>The control array is a &v4l2-ext-control; array. The
+<structname>v4l2_ext_control</structname> structure is very similar to
+&v4l2-control;, except for the fact that it also allows for 64-bit
+values and pointers to be passed.</para>
+
+ <para>It is important to realize that due to the flexibility of
+controls it is necessary to check whether the control you want to set
+actually is supported in the driver and what the valid range of values
+is. So use the &VIDIOC-QUERYCTRL; and &VIDIOC-QUERYMENU; ioctls to
+check this. Also note that it is possible that some of the menu
+indices in a control of type <constant>V4L2_CTRL_TYPE_MENU</constant>
+may not be supported (<constant>VIDIOC_QUERYMENU</constant> will
+return an error). A good example is the list of supported MPEG audio
+bitrates. Some drivers only support one or two bitrates, others
+support a wider range.</para>
+ </section>
+
+ <section>
+ <title>Enumerating Extended Controls</title>
+
+ <para>The recommended way to enumerate over the extended
+controls is by using &VIDIOC-QUERYCTRL; in combination with the
+<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag:</para>
+
+ <informalexample>
+ <programlisting>
+&v4l2-queryctrl; qctrl;
+
+qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
+while (0 == ioctl (fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
+ /* ... */
+ qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+}
+</programlisting>
+ </informalexample>
+
+ <para>The initial control ID is set to 0 ORed with the
+<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> flag. The
+<constant>VIDIOC_QUERYCTRL</constant> ioctl will return the first
+control with a higher ID than the specified one. When no such controls
+are found an error is returned.</para>
+
+ <para>If you want to get all controls within a specific control
+class, then you can set the initial
+<structfield>qctrl.id</structfield> value to the control class and add
+an extra check to break out of the loop when a control of another
+control class is found:</para>
+
+ <informalexample>
+ <programlisting>
+qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
+while (0 == ioctl (fd, &VIDIOC-QUERYCTRL;, &amp;qctrl)) {
+ if (V4L2_CTRL_ID2CLASS (qctrl.id) != V4L2_CTRL_CLASS_MPEG)
+ break;
+ /* ... */
+ qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+ }
+</programlisting>
+ </informalexample>
+
+ <para>The 32-bit <structfield>qctrl.id</structfield> value is
+subdivided into three bit ranges: the top 4 bits are reserved for
+flags (&eg; <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>) and are not
+actually part of the ID. The remaining 28 bits form the control ID, of
+which the most significant 12 bits define the control class and the
+least significant 16 bits identify the control within the control
+class. It is guaranteed that these last 16 bits are always non-zero
+for controls. The range of 0x1000 and up are reserved for
+driver-specific controls. The macro
+<constant>V4L2_CTRL_ID2CLASS(id)</constant> returns the control class
+ID based on a control ID.</para>
+
+ <para>If the driver does not support extended controls, then
+<constant>VIDIOC_QUERYCTRL</constant> will fail when used in
+combination with <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>. In
+that case the old method of enumerating control should be used (see
+1.8). But if it is supported, then it is guaranteed to enumerate over
+all controls, including driver-private controls.</para>
+ </section>
+
+ <section>
+ <title>Creating Control Panels</title>
+
+ <para>It is possible to create control panels for a graphical
+user interface where the user can select the various controls.
+Basically you will have to iterate over all controls using the method
+described above. Each control class starts with a control of type
+<constant>V4L2_CTRL_TYPE_CTRL_CLASS</constant>.
+<constant>VIDIOC_QUERYCTRL</constant> will return the name of this
+control class which can be used as the title of a tab page within a
+control panel.</para>
+
+ <para>The flags field of &v4l2-queryctrl; also contains hints on
+the behavior of the control. See the &VIDIOC-QUERYCTRL; documentation

+
+ <para>The result of a capture operation is determined by
+cropping and image format parameters. The former select an area of the
+video picture to capture, the latter how images are stored in memory,
+&ie; in RGB or YUV format, the number of bits per pixel or width and
+height. Together they also define how images are scaled in the
+process.</para>
+
+ <para>As usual these parameters are <emphasis>not</emphasis> reset

+
+ <para>Cropping initialization at minimum requires to reset the
+parameters to defaults. An example is given in <xref

+<structfield>fmt</structfield> union.</para>

+
+ <para>Like <constant>VIDIOC_S_FMT</constant> the

+without disabling I/O or possibly time consuming hardware
+preparations.</para>

+<constant>VIDIOC_G_FMT</constant>, <constant>VIDIOC_S_FMT</constant>

+capture devices must implement both the

+ <title>Video Overlay Interface</title>
+ <subtitle>Also known as Framebuffer Overlay or Previewing</subtitle>
+
+ <para>Video overlay devices have the ability to genlock (TV-)video
+into the (VGA-)video signal of a graphics card, or to store captured
+images directly in video memory of a graphics card, typically with
+clipping. This can be considerable more efficient than capturing
+images and displaying them by other means. In the old days when only
+nuclear power plants needed cooling towers this used to be the only
+way to put live video into a window.</para>
+
+ <para>Video overlay devices are accessed through the same character
+special files as <link linkend="capture">video capture</link> devices.
+Note the default function of a <filename>/dev/video</filename> device
+is video capturing. The overlay function is only available after
+calling the &VIDIOC-S-FMT; ioctl.</para>
+
+ <para>The driver may support simultaneous overlay and capturing
+using the read/write and streaming I/O methods. If so, operation at
+the nominal frame rate of the video standard is not guaranteed. Frames
+may be directed away from overlay to capture, or one field may be used
+for overlay and the other for capture if the capture parameters permit
+this.</para>
+
+ <para>Applications should use different file descriptors for
+capturing and overlay. This must be supported by all drivers capable
+of simultaneous capturing and overlay. Optionally these drivers may
+also permit capturing and overlay with a single file descriptor for
+compatibility with V4L and earlier versions of V4L2.<footnote>
+ <para>A common application of two file descriptors is the
+XFree86 <link linkend="xvideo">Xv/V4L</link> interface driver and
+a V4L2 application. While the X server controls video overlay, the
+application can take advantage of memory mapping and DMA.</para>
+ <para>In the opinion of the designers of this API, no driver
+writer taking the efforts to support simultaneous capturing and
+overlay will restrict this ability by requiring a single file
+descriptor, as in V4L and earlier versions of V4L2. Making this
+optional means applications depending on two file descriptors need
+backup routines to be compatible with all drivers, which is
+considerable more work than using two fds in applications which do
+not. Also two fd's fit the general concept of one file descriptor for
+each logical stream. Hence as a complexity trade-off drivers

+ <title>Raw VBI Data Interface</title>

+ <para>VBI is an abbreviation of Vertical Blanking Interval, a gap
+in the sequence of lines of an analog video signal. During VBI
+no picture information is transmitted, allowing some time while the
+electron beam of a cathode ray tube TV returns to the top of the
+screen. Using an oscilloscope you will find here the vertical
+synchronization pulses and short data packages ASK
+modulated<footnote><para>ASK: Amplitude-Shift Keying. A high signal

+onto the video signal. These are transmissions of services such as
+Teletext or Closed Caption.</para>
+
+ <para>Subject of this interface type is raw VBI data, as sampled off
+a video signal, or to be added to a signal for output.
+The data format is similar to uncompressed video images, a number of
+lines times a number of samples per line, we call this a VBI image.</para>

+device special files named <filename>/dev/vbi</filename> and
+<filename>/dev/vbi0</filename> to <filename>/dev/vbi31</filename> with
+major number 81 and minor numbers 224 to 255.
+<filename>/dev/vbi</filename> is typically a symbolic link to the

+devices.</para>
+
+ <para>To address the problems of finding related video and VBI

+ <title>Raw VBI Format Negotiation</title>
+
+ <para>Raw VBI sampling abilities can vary, in particular the
+sampling frequency. To properly interpret the data V4L2 specifies an
+ioctl to query the sampling parameters. Moreover, to allow for some
+flexibility applications can also suggest different parameters.</para>
+
+ <para>As usual these parameters are <emphasis>not</emphasis>
+reset at &func-open; time to permit Unix tool chains, programming a
+device and then reading from it as if it was a plain file. Well
+written V4L2 applications should always ensure they really get what
+they want, requesting reasonable parameters and then checking if the
+actual parameters are suitable.</para>
+
+ <para>To query the current raw VBI capture parameters
+applications set the <structfield>type</structfield> field of a
+&v4l2-format; to <constant>V4L2_BUF_TYPE_VBI_CAPTURE</constant> or
+<constant>V4L2_BUF_TYPE_VBI_OUTPUT</constant>, and call the
+&VIDIOC-G-FMT; ioctl with a pointer to this structure. Drivers fill
+the &v4l2-vbi-format; <structfield>vbi</structfield> member of the
+<structfield>fmt</structfield> union.</para>
+
+ <para>To request different parameters applications set the
+<structfield>type</structfield> field of a &v4l2-format; as above and
+initialize all fields of the &v4l2-vbi-format;
+<structfield>vbi</structfield> member of the
+<structfield>fmt</structfield> union, or better just modify the
+results of <constant>VIDIOC_G_FMT</constant>, and call the
+&VIDIOC-S-FMT; ioctl with a pointer to this structure. Drivers return
+an &EINVAL; only when the given parameters are ambiguous, otherwise
+they modify the parameters according to the hardware capabilites and
+return the actual parameters. When the driver allocates resources at
+this point, it may return an &EBUSY; to indicate the returned
+parameters are valid but the required resources are currently not
+available. That may happen for instance when the video and VBI areas
+to capture would overlap, or when the driver supports multiple opens
+and another process already requested VBI capturing or output. Anyway,
+applications must expect other resource allocation points which may
+return <errorcode>EBUSY</errorcode>, at the &VIDIOC-STREAMON; ioctl
+and the first read(), write() and select() call.</para>
+
+ <para>VBI devices must implement both the
+<constant>VIDIOC_G_FMT</constant> and
+<constant>VIDIOC_S_FMT</constant> ioctl, even if
+<constant>VIDIOC_S_FMT</constant> ignores all requests and always
+returns default parameters as <constant>VIDIOC_G_FMT</constant> does.

+ <para>To find out which data services are supported by the
+hardware applications can call the &VIDIOC-G-SLICED-VBI-CAP; ioctl.
+All drivers implementing the sliced VBI interface must support this
+ioctl. The results may differ from those of the &VIDIOC-S-FMT; ioctl
+when the number of VBI lines the hardware can capture or output per
+frame, or the number of services it can identify on a given line are
+limited. For example on PAL line 16 the hardware may be able to look
+for a VPS or Teletext signal, but not both at the same time.</para>
+
+ <para>To determine the currently selected services applications
+set the <structfield>type </structfield> field of &v4l2-format; to
+<constant> V4L2_BUF_TYPE_SLICED_VBI_CAPTURE</constant> or <constant>
+V4L2_BUF_TYPE_SLICED_VBI_OUTPUT</constant>, and the &VIDIOC-G-FMT;
+ioctl fills the <structfield>fmt.sliced</structfield> member, a
+&v4l2-sliced-vbi-format;.</para>
+
+ <para>Applications can request different parameters by
+initializing or modifying the <structfield>fmt.sliced</structfield>
+member and calling the &VIDIOC-S-FMT; ioctl with a pointer to the
+<structname>v4l2_format</structname> structure.</para>
+
+ <para>The sliced VBI API is more complicated than the raw VBI API
+because the hardware must be told which VBI service to expect on each
+scan line. Not all services may be supported by the hardware on all
+lines (this is especially true for VBI output where Teletext is often
+unsupported and other services can only be inserted in one specific
+line). In many cases, however, it is sufficient to just set the
+<structfield>service_set</structfield> field to the required services
+and let the driver fill the <structfield>service_lines</structfield>
+array according to hardware capabilities. Only if more precise control
+is needed should the programmer set the
+<structfield>service_lines</structfield> array explicitly.</para>
+
+ <para>The &VIDIOC-S-FMT; ioctl modifies the parameters
+according to hardware capabilities. When the driver allocates
+resources at this point, it may return an &EBUSY; if the required
+resources are temporarily unavailable. Other resource allocation
+points which may return <errorcode>EBUSY</errorcode> can be the
+&VIDIOC-STREAMON; ioctl and the first &func-read;, &func-write; and
+&func-select; call.</para>

+ <para>This interface aims at devices receiving and demodulating
+Teletext data [<xref linkend="ets300706" />, <xref linkend="itu653" />], evaluating the
+Teletext packages and storing formatted pages in cache memory. Such
+devices are usually implemented as microcontrollers with serial
+interface (I<superscript>2</superscript>C) and can be found on older
+TV cards, dedicated Teletext decoding cards and home-brew devices
+connected to the PC parallel port.</para>
+
+ <para>The Teletext API was designed by Martin Buck. It is defined in
+the kernel header file <filename>linux/videotext.h</filename>, the
+specification is available from <ulink url="ftp://ftp.gwdg.de/pub/linux/misc/videotext/">
+ftp://ftp.gwdg.de/pub/linux/misc/videotext/</ulink>. (Videotext is the name of
+the German public television Teletext service.) Conventional character
+device file names are <filename>/dev/vtx</filename> and
+<filename>/dev/vttuner</filename>, with device number 83, 0 and 83, 16
+respectively. A similar interface exists for the Philips SAA5249
+Teletext decoder [specification?] with character device file names
+<filename>/dev/tlkN</filename>, device number 102, N.</para>
+
+ <para>Eventually the Teletext API was integrated into the V4L API
+with character device file names <filename>/dev/vtx0</filename> to
+<filename>/dev/vtx31</filename>, device major number 81, minor numbers
+192 to 223. For reference the V4L Teletext API specification is
+reproduced here in full: "Teletext interfaces talk the existing VTX
+API." Teletext devices with major number 83 and 102 will be removed in
+Linux 2.6.</para>
+
+ <para>There are no plans to replace the Teletext API or to integrate
+it into V4L2. Please write to the linux-media mailing list: &v4l-ml;

+
+ <para>The <function>ioctl()</function> function is used to program
+V4L2 devices. The argument <parameter>fd</parameter> must be an open

+in it whether the argument is an input, output or read/write
+parameter, and the size of the argument <parameter>argp</parameter> in
+bytes. Macros and defines specifying V4L2 ioctl requests are located
+in the <link linkend="videodev">videodev.h</link> header file.
+Applications should use their own copy, not include the version in the
+kernel sources on the system they compile on. All V4L2 ioctl requests,

+output or read/write parameter it remains unmodified, and the
+<varname>errno</varname> variable is set appropriately. See below for
+possible error codes. Generic errors like <errorcode>EBADF</errorcode>
+or <errorcode>EFAULT</errorcode> are not listed in the sections

+<parameter>fd</parameter> into the buffer starting at
+<parameter>buf</parameter>. The layout of the data in the buffer is
+discussed in the respective device interface section, see ##. If <parameter>count</parameter> is zero,
+<function>read()</function> returns zero and has no other results. If
+<parameter>count</parameter> is greater than
+<constant>SSIZE_MAX</constant>, the result is unspecified. Regardless
+of the <parameter>count</parameter> value each
+<function>read()</function> call will provide at most one frame (two
+fields) worth of data.</para>
+
+ <para>By default <function>read()</function> blocks until data
+becomes available. When the <constant>O_NONBLOCK</constant> flag was
+given to the &func-open; function it
+returns immediately with an &EAGAIN; when no data is available. The
+&func-select; or &func-poll; functions
+can always be used to suspend execution until data becomes available. All
+drivers supporting the <function>read()</function> function must also
+support <function>select()</function> and
+<function>poll()</function>.</para>
+
+ <para>Drivers can implement read functionality in different
+ways, using a single or multiple buffers and discarding the oldest or
+newest frames once the internal buffers are filled.</para>
+
+ <para><function>read()</function> never returns a "snapshot" of a
+buffer being filled. Using a single buffer the driver will stop
+capturing when the application starts reading the buffer until the
+read is finished. Thus only the period of the vertical blanking
+interval is available for reading, or the capture rate must fall below
+the nominal frame rate of the video standard.</para>
+
+<para>The behavior of
+<function>read()</function> when called during the active picture
+period or the vertical blanking separating the top and bottom field
+depends on the discarding policy. A driver discarding the oldest
+frames keeps capturing into an internal buffer, continuously
+overwriting the previously, not read frame, and returns the frame
+being received at the time of the <function>read()</function> call as
+soon as it is complete.</para>
+
+ <para>A driver discarding the newest frames stops capturing until
+the next <function>read()</function> call. The frame being received at
+<function>read()</function> time is discarded, returning the following
+frame instead. Again this implies a reduction of the capture rate to
+one half or less of the nominal frame rate. An example of this model
+is the video read mode of the bttv driver, initiating a DMA to user
+memory when <function>read()</function> is called and returning when
+the DMA finished.</para>
+
+ <para>In the multiple buffer model drivers maintain a ring of
+internal buffers, automatically advancing to the next free buffer.
+This allows continuous capturing when the application can empty the
+buffers fast enough. Again, the behavior when the driver runs out of
+free buffers depends on the discarding policy.</para>
+
+ <para>Applications can get and set the number of buffers used
+internally by the driver with the &VIDIOC-G-PARM; and &VIDIOC-S-PARM;
+ioctls. They are optional, however. The discarding policy is not
+reported and cannot be changed. For minimum requirements see <xref

+ <title>Input/Output</title>
+
+ <para>The V4L2 API defines several different methods to read from or
+write to a device. All drivers exchanging data with applications must
+support at least one of them.</para>
+
+ <para>The classic I/O method using the <function>read()</function>
+and <function>write()</function> function is automatically selected
+after opening a V4L2 device. When the driver does not support this
+method attempts to read or write will fail at any time.</para>
+
+ <para>Other methods must be negotiated. To select the streaming I/O
+method with memory mapped or user buffers applications call the
+&VIDIOC-REQBUFS; ioctl. The asynchronous I/O method is not defined
+yet.</para>
+
+ <para>Video overlay can be considered another I/O method, although
+the application does not directly receive the image data. It is
+selected by initiating video overlay with the &VIDIOC-S-FMT; ioctl.
+For more information see <xref linkend="overlay" />.</para>
+
+ <para>Generally exactly one I/O method, including overlay, is
+associated with each file descriptor. The only exceptions are
+applications not exchanging data with a driver ("panel applications",
+see <xref linkend="open" />) and drivers permitting simultaneous video capturing
+and overlay using the same file descriptor, for compatibility with V4L
+and earlier versions of V4L2.</para>
+
+ <para><constant>VIDIOC_S_FMT</constant> and
+<constant>VIDIOC_REQBUFS</constant> would permit this to some degree,
+but for simplicity drivers need not support switching the I/O method
+(after first switching away from read/write) other than by closing
+and reopening the device.</para>
+
+ <para>The following sections describe the various I/O methods in
+more detail.</para>
+
+ <section id="rw">
+ <title>Read/Write</title>
+
+ <para>Input and output devices support the
+<function>read()</function> and <function>write()</function> function,
+respectively, when the <constant>V4L2_CAP_READWRITE</constant> flag in
+the <structfield>capabilities</structfield> field of &v4l2-capability;
+returned by the &VIDIOC-QUERYCAP; ioctl is set.</para>
+
+ <para>Drivers may need the CPU to copy the data, but they may also
+support DMA to or from user memory, so this I/O method is not
+necessarily less efficient than other methods merely exchanging buffer
+pointers. It is considered inferior though because no meta-information
+like frame counters or timestamps are passed. This information is
+necessary to recognize frame dropping and to synchronize with other
+data streams. However this is also the simplest I/O method, requiring
+little or no setup to exchange data. It permits command line stunts
+like this (the <application>vidctrl</application> tool is
+fictitious):</para>
+
+ <informalexample>
+ <screen>
+&gt; vidctrl /dev/video --input=0 --format=YUYV --size=352x288
+&gt; dd if=/dev/video of=myimage.422 bs=202752 count=1
+</screen>
+ </informalexample>
+
+ <para>To read from the device applications use the
+&func-read; function, to write the &func-write; function.
+Drivers must implement one I/O method if they
+exchange data with applications, but it need not be this.<footnote>
+ <para>It would be desirable if applications could depend on
+drivers supporting all I/O interfaces, but as much as the complex
+memory mapping I/O can be inadequate for some devices we have no
+reason to require this interface, which is most useful for simple
+applications capturing still images.</para>
+ </footnote> When reading or writing is supported, the driver
+must also support the &func-select; and &func-poll;
+function.<footnote>
+ <para>At the driver level <function>select()</function> and
+<function>poll()</function> are the same, and
+<function>select()</function> is too important to be optional.</para>
+ </footnote></para>

+
+ <section id="mmap">
+ <title>Streaming I/O (Memory Mapping)</title>
+
+ <para>Input and output devices support this I/O method when the
+<constant>V4L2_CAP_STREAMING</constant> flag in the
+<structfield>capabilities</structfield> field of &v4l2-capability;
+returned by the &VIDIOC-QUERYCAP; ioctl is set. There are two
+streaming methods, to determine if the memory mapping flavor is
+supported applications must call the &VIDIOC-REQBUFS; ioctl.</para>
+
+ <para>Streaming is an I/O method where only pointers to buffers
+are exchanged between application and driver, the data itself is not
+copied. Memory mapping is primarily intended to map buffers in device
+memory into the application's address space. Device memory can be for
+example the video memory on a graphics card with a video capture
+add-on. However, being the most efficient I/O method available for a
+long time, many other drivers support streaming as well, allocating
+buffers in DMA-able main memory.</para>
+
+ <para>A driver can support many sets of buffers. Each set is
+identified by a unique buffer type value. The sets are independent and
+each set can hold a different type of data. To access different sets
+at the same time different file descriptors must be used.<footnote>
+ <para>One could use one file descriptor and set the buffer
+type field accordingly when calling &VIDIOC-QBUF; etc., but it makes
+the <function>select()</function> function ambiguous. We also like the
+clean approach of one file descriptor per logical stream. Video
+overlay for example is also a logical stream, although the CPU is not
+needed for continuous operation.</para>
+ </footnote></para>
+
+ <para>To allocate device buffers applications call the
+&VIDIOC-REQBUFS; ioctl with the desired number of buffers and buffer
+type, for example <constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>.
+This ioctl can also be used to change the number of buffers or to free
+the allocated memory, provided none of the buffers are still
+mapped.</para>
+
+ <para>Before applications can access the buffers they must map
+them into their address space with the &func-mmap; function. The
+location of the buffers in device memory can be determined with the
+&VIDIOC-QUERYBUF; ioctl. The <structfield>m.offset</structfield> and
+<structfield>length</structfield> returned in a &v4l2-buffer; are
+passed as sixth and second parameter to the
+<function>mmap()</function> function. The offset and length values
+must not be modified. Remember the buffers are allocated in physical
+memory, as opposed to virtual memory which can be swapped out to disk.
+Applications should free the buffers as soon as possible with the
+&func-munmap; function.</para>

+
+ <para>Conceptually streaming drivers maintain two buffer queues, an incoming
+and an outgoing queue. They separate the synchronous capture or output
+operation locked to a video clock from the application which is
+subject to random disk or network delays and preemption by
+other processes, thereby reducing the probability of data loss.
+The queues are organized as FIFOs, buffers will be
+output in the order enqueued in the incoming FIFO, and were
+captured in the order dequeued from the outgoing FIFO.</para>
+
+ <para>The driver may require a minimum number of buffers enqueued
+at all times to function, apart of this no limit exists on the number
+of buffers applications can enqueue in advance, or dequeue and
+process. They can also enqueue in a different order than buffers have
+been dequeued, and the driver can <emphasis>fill</emphasis> enqueued
+<emphasis>empty</emphasis> buffers in any order. <footnote>
+ <para>Random enqueue order permits applications processing
+images out of order (such as video codecs) to return buffers earlier,
+reducing the probability of data loss. Random fill order allows
+drivers to reuse buffers on a LIFO-basis, taking advantage of caches
+holding scatter-gather lists and the like.</para>
+ </footnote> The index number of a buffer (&v4l2-buffer;
+<structfield>index</structfield>) plays no role here, it only
+identifies the buffer.</para>
+
+ <para>Initially all mapped buffers are in dequeued state,
+inaccessible by the driver. For capturing applications it is customary
+to first enqueue all mapped buffers, then to start capturing and enter
+the read loop. Here the application waits until a filled buffer can be
+dequeued, and re-enqueues the buffer when the data is no longer
+needed. Output applications fill and enqueue buffers, when enough
+buffers are stacked up the output is started with
+<constant>VIDIOC_STREAMON</constant>. In the write loop, when
+the application runs out of free buffers, it must wait until an empty
+buffer can be dequeued and reused.</para>
+
+ <para>To enqueue and dequeue a buffer applications use the
+&VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl. The status of a buffer being
+mapped, enqueued, full or empty can be determined at any time using the
+&VIDIOC-QUERYBUF; ioctl. Two methods exist to suspend execution of the
+application until one or more buffers can be dequeued. By default
+<constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the
+outgoing queue. When the <constant>O_NONBLOCK</constant> flag was
+given to the &func-open; function, <constant>VIDIOC_DQBUF</constant>
+returns immediately with an &EAGAIN; when no buffer is available. The
+&func-select; or &func-poll; function are always available.</para>
+
+ <para>To start and stop capturing or output applications call the
+&VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctl. Note
+<constant>VIDIOC_STREAMOFF</constant> removes all buffers from both
+queues as a side effect. Since there is no notion of doing anything
+"now" on a multitasking system, if an application needs to synchronize
+with another event it should examine the &v4l2-buffer;
+<structfield>timestamp</structfield> of captured buffers, or set the
+field before enqueuing buffers for output.</para>
+
+ <para>Drivers implementing memory mapping I/O must

+ <para>Buffer addresses and sizes are passed on the fly with the
+&VIDIOC-QBUF; ioctl. Although buffers are commonly cycled,
+applications can pass different addresses and sizes at each
+<constant>VIDIOC_QBUF</constant> call. If required by the hardware the
+driver swaps memory pages within physical memory to create a
+continuous area of memory. This happens transparently to the
+application in the virtual memory subsystem of the kernel. When buffer
+pages have been swapped out to disk they are brought back and finally
+locked in physical memory for DMA.<footnote>
+ <para>We expect that frequently used buffers are typically not
+swapped out. Anyway, the process of swapping, locking or generating
+scatter-gather lists may be time consuming. The delay can be masked by
+the depth of the incoming buffer queue, and perhaps by maintaining
+caches assuming a buffer will be soon enqueued again. On the other
+hand, to optimize memory usage drivers can limit the number of buffers
+locked in advance and recycle the most recently used buffers first. Of
+course, the pages of empty buffers in the incoming queue need not be
+saved to disk. Output buffers must be saved on the incoming and
+outgoing queue because an application may share them with other
+processes.</para>
+ </footnote></para>
+
+ <para>Filled or displayed buffers are dequeued with the
+&VIDIOC-DQBUF; ioctl. The driver can unlock the memory pages at any
+time between the completion of the DMA and this ioctl. The memory is
+also unlocked when &VIDIOC-STREAMOFF; is called, &VIDIOC-REQBUFS;, or
+when the device is closed. Applications must take care not to free
+buffers without dequeuing. For once, the buffers remain locked until
+further, wasting physical memory. Second the driver will not be
+notified when the memory is returned to the application's free list
+and subsequently reused for other purposes, possibly completing the
+requested DMA and overwriting valuable data.</para>

+ <para>For capturing applications it is customary to enqueue a
+number of empty buffers, to start capturing and enter the read loop.
+Here the application waits until a filled buffer can be dequeued, and
+re-enqueues the buffer when the data is no longer needed. Output
+applications fill and enqueue buffers, when enough buffers are stacked
+up output is started. In the write loop, when the application
+runs out of free buffers it must wait until an empty buffer can be
+dequeued and reused. Two methods exist to suspend execution of the
+application until one or more buffers can be dequeued. By default
+<constant>VIDIOC_DQBUF</constant> blocks when no buffer is in the
+outgoing queue. When the <constant>O_NONBLOCK</constant> flag was
+given to the &func-open; function, <constant>VIDIOC_DQBUF</constant>
+returns immediately with an &EAGAIN; when no buffer is available. The
+&func-select; or &func-poll; function are always available.</para>
+
+ <para>To start and stop capturing or output applications call the
+&VIDIOC-STREAMON; and &VIDIOC-STREAMOFF; ioctl. Note
+<constant>VIDIOC_STREAMOFF</constant> removes all buffers from both
+queues and unlocks all buffers as a side effect. Since there is no
+notion of doing anything "now" on a multitasking system, if an
+application needs to synchronize with another event it should examine
+the &v4l2-buffer; <structfield>timestamp</structfield> of captured
+buffers, or set the field before enqueuing buffers for output.</para>

+
+ <para>A buffer contains data exchanged by application and
+driver using one of the Streaming I/O methods. Only pointers to
+buffers are exchanged, the data itself is not copied. These pointers,
+together with meta-information like timestamps or field parity, are
+stored in a struct <structname>v4l2_buffer</structname>, argument to
+the &VIDIOC-QUERYBUF;, &VIDIOC-QBUF; and &VIDIOC-DQBUF; ioctl.</para>
+
+ <para>Nominally timestamps refer to the first data byte transmitted.
+In practice however the wide range of hardware covered by the V4L2 API
+limits timestamp accuracy. Often an interrupt routine will
+sample the system clock shortly after the field or frame was stored
+completely in memory. So applications must expect a constant
+difference up to one field or frame period plus a small (few scan
+lines) random error. The delay and error can be much
+larger due to compression or transmission over an external bus when
+the frames are not properly stamped by the sender. This is frequently
+the case with USB cameras. Here timestamps refer to the instant the
+field or frame was received by the driver, not the capture time. These
+devices identify by not enumerating any video standards, see <xref
+linkend="standard" />.</para>
+
+ <para>Similar limitations apply to output timestamps. Typically
+the video hardware locks to a clock controlling the video timing, the
+horizontal and vertical synchronization pulses. At some point in the
+line sequence, possibly the vertical blanking, an interrupt routine
+samples the system clock, compares against the timestamp and programs
+the hardware to repeat the previous field or frame, or to display the
+buffer contents.</para>
+
+ <para>Apart of limitations of the video device and natural
+inaccuracies of all clocks, it should be noted system time itself is
+not perfectly stable. It can be affected by power saving cycles,
+warped to insert leap seconds, or even turned back or forth by the
+system administrator affecting long term measurements. <footnote>
+ <para>Since no other Linux multimedia
+API supports unadjusted time it would be foolish to introduce here. We
+must use a universally supported clock to synchronize different media,
+hence time of day.</para>

+ <title>Field Order</title>
+
+ <para>We have to distinguish between progressive and interlaced
+video. Progressive video transmits all lines of a video image
+sequentially. Interlaced video divides an image into two fields,
+containing only the odd and even lines of the image, respectively.
+Alternating the so called odd and even field are transmitted, and due
+to a small delay between fields a cathode ray TV displays the lines
+interleaved, yielding the original frame. This curious technique was
+invented because at refresh rates similar to film the image would
+fade out too quickly. Transmitting fields reduces the flicker without
+the necessity of doubling the frame rate and with it the bandwidth
+required for each channel.</para>
+
+ <para>It is important to understand a video camera does not expose
+one frame at a time, merely transmitting the frames separated into
+fields. The fields are in fact captured at two different instances in
+time. An object on screen may well move between one field and the
+next. For applications analysing motion it is of paramount importance
+to recognize which field of a frame is older, the <emphasis>temporal
+order</emphasis>.</para>
+
+ <para>When the driver provides or accepts images field by field
+rather than interleaved, it is also important applications understand
+how the fields combine to frames. We distinguish between top and
+bottom fields, the <emphasis>spatial order</emphasis>: The first line
+of the top field is the first line of an interlaced frame, the first
+line of the bottom field is the second line of that frame.</para>
+
+ <para>However because fields were captured one after the other,
+arguing whether a frame commences with the top or bottom field is
+pointless. Any two successive top and bottom, or bottom and top fields
+yield a valid frame. Only when the source was progressive to begin
+with, &eg; when transferring film to video, two fields may come from
+the same frame, creating a natural order.</para>
+
+ <para>Counter to intuition the top field is not necessarily the
+older field. Whether the older field contains the top or bottom lines
+is a convention determined by the video standard. Hence the
+distinction between temporal and spatial order of fields. The diagrams
+below should make this clearer.</para>
+
+ <para>All video capture and output devices must report the current
+field order. Some drivers may permit the selection of a different
+order, to this end applications initialize the
+<structfield>field</structfield> field of &v4l2-pix-format; before

+ <title>Introduction</title>
+
+ <para>libv4l is a collection of libraries which adds a thin abstraction
+layer on top of video4linux2 devices. The purpose of this (thin) layer
+is to make it easy for application writers to support a wide variety of
+devices without having to write separate code for different devices in the

+</para>
+ <para>Later on libv4lconvert was expanded to also be able to do
+various video processing functions to improve webcam video quality.
+The video processing is split in to 2 parts: libv4lconvert/control and
+libv4lconvert/processing.</para>
+
+ <para>The control part is used to offer video controls which can
+be used to control the video processing functions made available by
+ libv4lconvert/processing. These controls are stored application wide
+(until reboot) by using a persistent shared memory object.</para>
+
+ <para>libv4lconvert/processing offers the actual video
+processing functionality.</para>
+ </section>
+ <section>
+ <title>libv4l1</title>
+ <para>This library offers functions that can be used to quickly
+make v4l1 applications work with v4l2 devices. These functions work exactly
+like the normal open/close/etc, except that libv4l1 does full emulation of
+the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it
+will just pass calls through.</para>
+ <para>Since those functions are emulations of the old V4L1 API,
+it shouldn't be used for new applications.</para>
+ </section>
+ <section>
+ <title>libv4l2</title>
+ <para>This library should be used for all modern V4L2
+applications.</para>
+ <para>It provides handles to call V4L2 open/ioctl/close/poll
+methods. Instead of just providing the raw output of the device, it enhances
+the calls in the sense that it will use libv4lconvert to provide more video
+formats and to enhance the image quality.</para>
+ <para>In most cases, libv4l2 just passes the calls directly
+through to the v4l2 driver, intercepting the calls to

+ <section>
+ <title>Standard Image Formats</title>
+
+ <para>In order to exchange images between drivers and
+applications, it is necessary to have standard image data formats
+which both sides will interpret the same way. V4L2 includes several
+such formats, and this section is intended to be an unambiguous
+specification of the standard image data formats in V4L2.</para>
+
+ <para>V4L2 drivers are not limited to these formats, however.
+Driver-specific formats are possible. In that case the application may
+depend on a codec to convert images to one of the standard formats
+when needed. But the data can still be stored and retrieved in the
+proprietary format. For example, a device may support a proprietary
+compressed format. Applications can still capture and save the data in
+the compressed format, saving much disk space, and later use a codec
+to convert the images to the X Windows screen format when the video is
+to be displayed.</para>
+
+ <para>Even so, ultimately, some standard formats are needed, so
+the V4L2 specification would not be complete without well-defined
+standard formats.</para>
+
+ <para>The V4L2 standard formats are mainly uncompressed formats. The
+pixels are always arranged in memory from left to right, and from top
+to bottom. The first byte of data in the image buffer is always for
+the leftmost pixel of the topmost row. Following that is the pixel
+immediately to its right, and so on until the end of the top row of
+pixels. Following the rightmost pixel of the row there may be zero or
+more bytes of padding to guarantee that each row of pixel data has a
+certain alignment. Following the pad bytes, if any, is data for the
+leftmost pixel of the second row from the top, and so on. The last row
+has just as many pad bytes after it as the other rows.</para>
+
+ <para>In V4L2 each format has an identifier which looks like
+<constant>PIX_FMT_XXX</constant>, defined in the <link
+linkend="videodev">videodev.h</link> header file. These identifiers
+represent <link linkend="v4l2-fourcc">four character codes</link>
+which are also listed below, however they are not the same as those
+used in the Windows world.</para>

+ <title>YUV Formats</title>
+
+ <para>YUV is the format native to TV broadcast and composite video
+signals. It separates the brightness information (Y) from the color
+information (U and V or Cb and Cr). The color information consists of
+red and blue <emphasis>color difference</emphasis> signals, this way
+the green component can be reconstructed by subtracting from the
+brightness component. See <xref linkend="colorspaces" /> for conversion
+examples. YUV was chosen because early television would only transmit
+brightness information. To add color in a way compatible with existing
+receivers a new signal carrier was added to transmit the color
+difference signals. Secondary in the YUV format the U and V components
+usually have lower resolution than the Y component. This is an analog
+video compression technique taking advantage of a property of the
+human visual system, being more sensitive to brightness
+information.</para>

+<title>Introduction</title>
+
+<para>Currently, most analog and digital devices have a Infrared input for remote controllers. Each
+manufacturer has their own type of control. It is not rare for the same manufacturer to ship different
+types of controls, depending on the device.</para>
+<para>Unfortunately, for several years, there was no effort to create uniform IR keycodes for
+different devices. This caused the same IR keyname to be mapped completely differently on
+different IR devices. This resulted that the same IR keyname to be mapped completely different on
+different IR's. Due to that, V4L2 API now specifies a standard for mapping Media keys on IR.</para>
+<para>This standard should be used by both V4L/DVB drivers and userspace applications</para>
+<para>The modules register the remote as keyboard within the linux input layer. This means that the IR key strokes will look like normal keyboard key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event devices (CONFIG_INPUT_EVDEV) it is possible for applications to access the remote via /dev/input/event devices.</para>

+<constant>VIDIOC_DBG_G_CHIP_IDENT</constant> fails with an &EINVAL;.</para>
+
+ <para>On success, the <structfield>ident</structfield> field will

+this chip.</para>
+
+ <para>When the driver could not identify the selected chip,

+functions.</para>
+ <para>The return value and the content of the
+<structfield>v4l2_frmivalenum.type</structfield> field depend on the
+type of frame intervals the device supports. Here are the semantics of
+the function for the different cases:</para>
+ <itemizedlist>
+ <listitem>
+ <para><emphasis role="bold">Discrete:</emphasis> The function
+returns success if the given index value (zero-based) is valid. The
+application should increase the index by one for each call until
+<constant>EINVAL</constant> is returned. The `v4l2_frmivalenum.type`
+field is set to `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the
+union only the `discrete` member is valid.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis role="bold">Step-wise:</emphasis> The function
+returns success if the given index value is zero and
+<constant>EINVAL</constant> for any other index value. The
+<structfield>v4l2_frmivalenum.type</structfield> field is set to
+<constant>V4L2_FRMIVAL_TYPE_STEPWISE</constant> by the driver. Of the
+union only the <structfield>stepwise</structfield> member is
+valid.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis role="bold">Continuous:</emphasis> This is a
+special case of the step-wise type above. The function returns success
+if the given index value is zero and <constant>EINVAL</constant> for
+any other index value. The
+<structfield>v4l2_frmivalenum.type</structfield> field is set to
+<constant>V4L2_FRMIVAL_TYPE_CONTINUOUS</constant> by the driver. Of
+the union only the <structfield>stepwise</structfield> member is valid
+and the <structfield>step</structfield> value is set to 1.</para>
+ </listitem>
+ </itemizedlist>
+
+ <para>When the application calls the function with index zero, it
+must check the <structfield>type</structfield> field to determine the
+type of frame interval enumeration the device supports. Only for the
+<constant>V4L2_FRMIVAL_TYPE_DISCRETE</constant> type does it make
+sense to increase the index value to receive more frame
+intervals.</para>
+ <para>Note that the order in which the frame intervals are
+returned has no special meaning. In particular does it not say
+anything about potential default frame intervals.</para>
+ <para>Applications can assume that the enumeration data does not
+change without any interaction from the application itself. This means
+that the enumeration data is consistent if the application does not
+perform any other ioctl calls while it runs the frame interval
+enumeration.</para>

+interface and may change in the future.</para>
+ </note>
+
+ <para>This ioctl allows applications to enumerate all frame sizes
+(&ie; width and height in pixels) that the device supports for the
+given pixel format.</para>
+ <para>The supported pixel formats can be obtained by using the
+&VIDIOC-ENUM-FMT; function.</para>
+ <para>The return value and the content of the
+<structfield>v4l2_frmsizeenum.type</structfield> field depend on the
+type of frame sizes the device supports. Here are the semantics of the
+function for the different cases:</para>
+
+ <itemizedlist>
+ <listitem>
+ <para><emphasis role="bold">Discrete:</emphasis> The function
+returns success if the given index value (zero-based) is valid. The
+application should increase the index by one for each call until
+<constant>EINVAL</constant> is returned. The
+<structfield>v4l2_frmsizeenum.type</structfield> field is set to
+<constant>V4L2_FRMSIZE_TYPE_DISCRETE</constant> by the driver. Of the
+union only the <structfield>discrete</structfield> member is
+valid.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis role="bold">Step-wise:</emphasis> The function
+returns success if the given index value is zero and
+<constant>EINVAL</constant> for any other index value. The
+<structfield>v4l2_frmsizeenum.type</structfield> field is set to
+<constant>V4L2_FRMSIZE_TYPE_STEPWISE</constant> by the driver. Of the
+union only the <structfield>stepwise</structfield> member is
+valid.</para>
+ </listitem>
+ <listitem>
+ <para><emphasis role="bold">Continuous:</emphasis> This is a
+special case of the step-wise type above. The function returns success
+if the given index value is zero and <constant>EINVAL</constant> for
+any other index value. The
+<structfield>v4l2_frmsizeenum.type</structfield> field is set to
+<constant>V4L2_FRMSIZE_TYPE_CONTINUOUS</constant> by the driver. Of
+the union only the <structfield>stepwise</structfield> member is valid
+and the <structfield>step_width</structfield> and
+<structfield>step_height</structfield> values are set to 1.</para>
+ </listitem>
+ </itemizedlist>
+
+ <para>When the application calls the function with index zero, it
+must check the <structfield>type</structfield> field to determine the
+type of frame size enumeration the device supports. Only for the
+<constant>V4L2_FRMSIZE_TYPE_DISCRETE</constant> type does it make
+sense to increase the index value to receive more frame sizes.</para>
+ <para>Note that the order in which the frame sizes are returned
+has no special meaning. In particular does it not say anything about
+potential default format sizes.</para>
+ <para>Applications can assume that the enumeration data does not
+change without any interaction from the application itself. This means
+that the enumeration data is consistent if the application does not
+perform any other ioctl calls while it runs the frame size
+enumeration.</para>

+ <title>Structs</title>
+
+ <para>In the structs below, <emphasis>IN</emphasis> denotes a
+value that has to be filled in by the application,
+<emphasis>OUT</emphasis> denotes values that the driver fills in. The
+application should zero out all members except for the
+<emphasis>IN</emphasis> fields.</para>

+ <para>The <constant>VIDIOC_G_ENC_INDEX</constant> ioctl provides
+meta data about a compressed video stream the same or another
+application currently reads from the driver, which is useful for
+random access into the stream without decoding it.</para>
+
+ <para>To read the data applications must call
+<constant>VIDIOC_G_ENC_INDEX</constant> with a pointer to a
+&v4l2-enc-idx;. On success the driver fills the
+<structfield>entry</structfield> array, stores the number of elements
+written in the <structfield>entries</structfield> field, and
+initializes the <structfield>entries_cap</structfield> field.</para>
+
+ <para>Each element of the <structfield>entry</structfield> array
+contains meta data about one picture. A
+<constant>VIDIOC_G_ENC_INDEX</constant> call reads up to
+<constant>V4L2_ENC_IDX_ENTRIES</constant> entries from a driver
+buffer, which can hold up to <structfield>entries_cap</structfield>
+entries. This number can be lower or higher than
+<constant>V4L2_ENC_IDX_ENTRIES</constant>, but not zero. When the

+
+ <para>If the <structfield>size</structfield> is too small to

+to a valid value and return an &ENOSPC;. You should re-allocate the
+string memory to this new size and try again. It is possible that the
+same issue occurs again if the string has grown in the meantime. It is
+recommended to call &VIDIOC-QUERYCTRL; first and use
+<structfield>maximum</structfield>+1 as the new <structfield>size</structfield>
+value. It is guaranteed that that is sufficient memory.

+
+ <para>Applications can use the <constant>VIDIOC_G_FBUF</constant> and
+<constant>VIDIOC_S_FBUF</constant> ioctl to get and set the
+framebuffer parameters for a <link linkend="overlay">Video
+Overlay</link> or <link linkend="osd">Video Output Overlay</link>
+(OSD). The type of overlay is implied by the device type (capture or
+output device) and can be determined with the &VIDIOC-QUERYCAP; ioctl.
+One <filename>/dev/videoN</filename> device must not support both
+kinds of overlay.</para>
+
+ <para>The V4L2 API distinguishes destructive and non-destructive
+overlays. A destructive overlay copies captured video images into the
+video memory of a graphics card. A non-destructive overlay blends
+video images into a VGA signal or graphics into a video signal.
+<wordasword>Video Output Overlays</wordasword> are always
+non-destructive.</para>
+
+ <para>To get the current parameters applications call the
+<constant>VIDIOC_G_FBUF</constant> ioctl with a pointer to a
+<structname>v4l2_framebuffer</structname> structure. The driver fills
+all fields of the structure or returns an &EINVAL; when overlays are
+not supported.</para>
+
+ <para>To set the parameters for a <wordasword>Video Output
+Overlay</wordasword>, applications must initialize the
+<structfield>flags</structfield> field of a struct
+<structname>v4l2_framebuffer</structname>. Since the framebuffer is
+implemented on the TV card all other parameters are determined by the
+driver. When an application calls <constant>VIDIOC_S_FBUF</constant>
+with a pointer to this structure, the driver prepares for the overlay
+and returns the framebuffer parameters as
+<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
+code.</para>
+
+ <para>To set the parameters for a <wordasword>non-destructive
+Video Overlay</wordasword>, applications must initialize the
+<structfield>flags</structfield> field, the
+<structfield>fmt</structfield> substructure, and call
+<constant>VIDIOC_S_FBUF</constant>. Again the driver prepares for the
+overlay and returns the framebuffer parameters as
+<constant>VIDIOC_G_FBUF</constant> does, or it returns an error
+code.</para>
+
+ <para>For a <wordasword>destructive Video Overlay</wordasword>
+applications must additionally provide a
+<structfield>base</structfield> address. Setting up a DMA to a
+random memory location can jeopardize the system security, its
+stability or even damage the hardware, therefore only the superuser
+can set the parameters for a destructive video overlay.</para>

+
+ <para>These ioctls are used to negotiate the format of data
+(typically image format) exchanged between driver and
+application.</para>
+
+ <para>To query the current parameters applications set the
+<structfield>type</structfield> field of a struct
+<structname>v4l2_format</structname> to the respective buffer (stream)
+type. For example video capture devices use
+<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE</constant>. When the application
+calls the <constant>VIDIOC_G_FMT</constant> ioctl with a pointer to
+this structure the driver fills the respective member of the
+<structfield>fmt</structfield> union. In case of video capture devices
+that is the &v4l2-pix-format; <structfield>pix</structfield> member.
+When the requested buffer type is not supported drivers return an
+&EINVAL;.</para>
+
+ <para>To change the current format parameters applications
+initialize the <structfield>type</structfield> field and all
+fields of the respective <structfield>fmt</structfield>
+union member. For details see the documentation of the various devices
+types in <xref linkend="devices" />. Good practice is to query the
+current parameters first, and to
+modify only those parameters not suitable for the application. When
+the application calls the <constant>VIDIOC_S_FMT</constant> ioctl
+with a pointer to a <structname>v4l2_format</structname> structure
+the driver checks
+and adjusts the parameters against hardware abilities. Drivers
+should not return an error code unless the input is ambiguous, this is
+a mechanism to fathom device capabilities and to approach parameters
+acceptable for both the application and driver. On success the driver
+may program the hardware, allocate resources and generally prepare for
+data exchange.
+Finally the <constant>VIDIOC_S_FMT</constant> ioctl returns the
+current format parameters as <constant>VIDIOC_G_FMT</constant> does.
+Very simple, inflexible devices may even ignore all input and always
+return the default parameters. However all V4L2 devices exchanging
+data with the application must implement the
+<constant>VIDIOC_G_FMT</constant> and
+<constant>VIDIOC_S_FMT</constant> ioctl. When the requested buffer
+type is not supported drivers return an &EINVAL; on a
+<constant>VIDIOC_S_FMT</constant> attempt. When I/O is already in
+progress or the resource is not available for other reasons drivers
+return the &EBUSY;.</para>
+
+ <para>The <constant>VIDIOC_TRY_FMT</constant> ioctl is equivalent
+to <constant>VIDIOC_S_FMT</constant> with one exception: it does not
+change driver state. It can also be called at any time, never
+returning <errorcode>EBUSY</errorcode>. This function is provided to
+negotiate parameters, to learn about hardware limitations, without
+disabling I/O or possibly time consuming hardware preparations.
+Although strongly recommended drivers are not required to implement
+this ioctl.</para>

+ <para>To query the attributes of a control applications set the
+<structfield>id</structfield> field of a &v4l2-queryctrl; and call the
+<constant>VIDIOC_QUERYCTRL</constant> ioctl with a pointer to this
+structure. The driver fills the rest of the structure or returns an
+&EINVAL; when the <structfield>id</structfield> is invalid.</para>
+
+ <para>It is possible to enumerate controls by calling
+<constant>VIDIOC_QUERYCTRL</constant> with successive
+<structfield>id</structfield> values starting from
+<constant>V4L2_CID_BASE</constant> up to and exclusive
+<constant>V4L2_CID_BASE_LASTP1</constant>. Drivers may return
+<errorcode>EINVAL</errorcode> if a control in this range is not
+supported. Further applications can enumerate private controls, which
+are not defined in this specification, by starting at
+<constant>V4L2_CID_PRIVATE_BASE</constant> and incrementing
+<structfield>id</structfield> until the driver returns
+<errorcode>EINVAL</errorcode>.</para>
+
+ <para>In both cases, when the driver sets the
+<constant>V4L2_CTRL_FLAG_DISABLED</constant> flag in the
+<structfield>flags</structfield> field this control is permanently
+disabled and should be ignored by the application.<footnote>
+ <para><constant>V4L2_CTRL_FLAG_DISABLED</constant> was
+intended for two purposes: Drivers can skip predefined controls not
+supported by the hardware (although returning EINVAL would do as
+well), or disable predefined and private controls after hardware
+detection without the trouble of reordering control arrays and indices
+(EINVAL cannot be used to skip private controls because it would
+prematurely end the enumeration).</para></footnote></para>
+
+ <para>When the application ORs <structfield>id</structfield> with
+<constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> the driver returns the
+next supported control, or <errorcode>EINVAL</errorcode> if there is
+none. Drivers which do not support this flag yet always return
+<errorcode>EINVAL</errorcode>.</para>
+
+ <para>Additional information is required for menu controls: the
+names of the menu items. To query them applications set the
+<structfield>id</structfield> and <structfield>index</structfield>
+fields of &v4l2-querymenu; and call the
+<constant>VIDIOC_QUERYMENU</constant> ioctl with a pointer to this
+structure. The driver fills the rest of the structure or returns an
+&EINVAL; when the <structfield>id</structfield> or

+by calling <constant>VIDIOC_QUERYMENU</constant> with successive

+I/O. Memory mapped buffers are located in device memory and must be
+allocated with this ioctl before they can be mapped into the
+application's address space. User buffers are allocated by
+applications themselves, and this ioctl is merely used to switch the
+driver into user pointer I/O mode.</para>
+
+ <para>To allocate device buffers applications initialize three
+fields of a <structname>v4l2_requestbuffers</structname> structure.
+They set the <structfield>type</structfield> field to the respective
+stream or buffer type, the <structfield>count</structfield> field to
+the desired number of buffers, and <structfield>memory</structfield>
+must be set to <constant>V4L2_MEMORY_MMAP</constant>. When the ioctl
+is called with a pointer to this structure the driver attempts to
+allocate the requested number of buffers and stores the actual number
+allocated in the <structfield>count</structfield> field. It can be
+smaller than the number requested, even zero, when the driver runs out
+of free memory. A larger number is possible when the driver requires
+more buffers to function correctly.<footnote>
+ <para>For example video output requires at least two buffers,
+one displayed and one filled by the application.</para>
+ </footnote> When memory mapping I/O is not supported the ioctl
+returns an &EINVAL;.</para>
+
+ <para>Applications can call <constant>VIDIOC_REQBUFS</constant>
+again to change the number of buffers, however this cannot succeed
+when any buffers are still mapped. A <structfield>count</structfield>
+value of zero frees all buffers, after aborting or finishing any DMA
+in progress, an implicit &VIDIOC-STREAMOFF;. <!-- mhs: I see no
+reason why munmap()ping one or even all buffers must imply
+streamoff.--></para>
+
+ <para>To negotiate user pointer I/O, applications initialize only
+the <structfield>type</structfield> field and set
+<structfield>memory</structfield> to
+<constant>V4L2_MEMORY_USERPTR</constant>. When the ioctl is called

+The OMAP PM interface
+=====================
+
+This document describes the temporary OMAP PM interface. Driver
+authors use these functions to communicate minimum latency or
+throughput constraints to the kernel power management code.
+Over time, the intention is to merge features from the OMAP PM
+interface into the Linux PM QoS code.
+
+Drivers need to express PM parameters which:
+
+- support the range of power management parameters present in the TI SRF;
+
+- separate the drivers from the underlying PM parameter
+ implementation, whether it is the TI SRF or Linux PM QoS or Linux
+ latency framework or something else;
+
+- specify PM parameters in terms of fundamental units, such as
+ latency and throughput, rather than units which are specific to OMAP
+ or to particular OMAP variants;
+
+- allow drivers which are shared with other architectures (e.g.,
+ DaVinci) to add these constraints in a way which won't affect non-OMAP
+ systems,
+
+- can be implemented immediately with minimal disruption of other
+ architectures.
+
+
+This document proposes the OMAP PM interface, including the following
+five power management functions for driver code:

+Further documentation for all OMAP PM interface functions can be
+found in arch/arm/plat-omap/include/mach/omap-pm.h.
+
+
+The OMAP PM layer is intended to be temporary
+---------------------------------------------
+
+The intention is that eventually the Linux PM QoS layer should support
+the range of power management features present in OMAP3. As this
+happens, existing drivers using the OMAP PM interface can be modified
+to use the Linux PM QoS code; and the OMAP PM interface can disappear.
+
+
+Driver usage of the OMAP PM functions
+-------------------------------------
+
+As the 'pdata' in the above examples indicates, these functions are
+exposed to drivers through function pointers in driver .platform_data
+structures. The function pointers are initialized by the board-*.c
+files to point to the corresponding OMAP PM functions:
+.set_max_dev_wakeup_lat will point to
+omap_pm_set_max_dev_wakeup_lat(), etc. Other architectures which do
+not support these functions should leave these function pointers set
+to NULL. Drivers should use the following idiom:
+
+ if (pdata->set_max_dev_wakeup_lat)
+ (*pdata->set_max_dev_wakeup_lat)(dev, t);
+
+The most common usage of these functions will probably be to specify
+the maximum time from when an interrupt occurs, to when the device
+becomes accessible. To accomplish this, driver writers should use the
+set_max_mpu_wakeup_lat() function to to constrain the MPU wakeup
+latency, and the set_max_dev_wakeup_lat() function to constrain the
+device wakeup latency (from clk_enable() to accessibility). For
+example,
+
+ /* Limit MPU wakeup latency */
+ if (pdata->set_max_mpu_wakeup_lat)
+ (*pdata->set_max_mpu_wakeup_lat)(dev, tc);
+
+ /* Limit device powerdomain wakeup latency */
+ if (pdata->set_max_dev_wakeup_lat)
+ (*pdata->set_max_dev_wakeup_lat)(dev, td);
+
+ /* total wakeup latency in this example: (tc + td) */
+
+The PM parameters can be overwritten by calling the function again
+with the new value. The settings can be removed by calling the
+function with a t argument of -1 (except in the case of
+set_max_bus_tput(), which should be called with an r argument of 0).
+
+The fifth function above, omap_pm_get_dev_context_loss_count(),
+is intended as an optimization to allow drivers to determine whether the
+device has lost its internal context. If context has been lost, the
+driver must restore its internal context before proceeding.
+
+
+Other specialized interface functions
+-------------------------------------
+
+The five functions listed above are intended to be usable by any
+device driver. DSPBridge and CPUFreq have a few special requirements.
+DSPBridge expresses target DSP performance levels in terms of OPP IDs.
+CPUFreq expresses target MPU performance levels in terms of MPU
+frequency. The OMAP PM interface contains functions for these
+specialized cases to convert that input information (OPPs/MPU
+frequency) into the form that the underlying power management
+implementation needs:
+
+6. (*pdata->dsp_get_opp_table)(void)
+
+7. (*pdata->dsp_set_min_opp)(u8 opp_id)
+
+8. (*pdata->dsp_get_opp)(void)
+
+9. (*pdata->cpu_get_freq_table)(void)
+
+10. (*pdata->cpu_set_freq)(unsigned long f)
+
+11. (*pdata->cpu_get_freq)(void)

+7. Soft limits
+
+Soft limits allow for greater sharing of memory. The idea behind soft limits
+is to allow control groups to use as much of the memory as needed, provided
+
+a. There is no memory contention
+b. They do not exceed their hard limit
+
+When the system detects memory contention or low memory control groups
+are pushed back to their soft limits. If the soft limit of each control
+group is very high, they are pushed back as much as possible to make
+sure that one control group does not starve the others of memory.
+
+Please note that soft limits is a best effort feature, it comes with
+no guarantees, but it does its best to make sure that when memory is
+heavily contended for, memory is allocated based on the soft limit
+hints/setup. Currently soft limit based reclaim is setup such that
+it gets invoked from balance_pgdat (kswapd).
+
+7.1 Interface
+
+Soft limits can be setup by using the following commands (in this example we
+assume a soft limit of 256 megabytes)
+
+# echo 256M > memory.soft_limit_in_bytes
+
+If we want to change this to 1G, we can at any time use
+
+# echo 1G > memory.soft_limit_in_bytes
+
+NOTE1: Soft limits take effect over a long period of time, since they involve
+ reclaiming memory for balancing between memory cgroups
+NOTE2: It is recommended to set the soft limit always below the hard limit,
+ otherwise the hard limit will take precedence.

+================================
+Driver for EP93xx LCD controller
+================================
+
+The EP93xx LCD controller can drive both standard desktop monitors and
+embedded LCD displays. If you have a standard desktop monitor then you
+can use the standard Linux video mode database. In your board file:
+
+ static struct ep93xxfb_mach_info some_board_fb_info = {
+ .num_modes = EP93XXFB_USE_MODEDB,
+ .bpp = 16,
+ };
+
+If you have an embedded LCD display then you need to define a video
+mode for it as follows:
+
+ static struct fb_videomode some_board_video_modes[] = {
+ {
+ .name = "some_lcd_name",
+ /* Pixel clock, porches, etc */
+ },
+ };
+
+Note that the pixel clock value is in pico-seconds. You can use the
+KHZ2PICOS macro to convert the pixel clock value. Most other values
+are in pixel clocks. See Documentation/fb/framebuffer.txt for further
+details.
+
+The ep93xxfb_mach_info structure for your board should look like the
+following:
+
+ static struct ep93xxfb_mach_info some_board_fb_info = {
+ .num_modes = ARRAY_SIZE(some_board_video_modes),
+ .modes = some_board_video_modes,
+ .default_mode = &some_board_video_modes[0],
+ .bpp = 16,
+ };
+
+The framebuffer device can be registered by adding the following to
+your board initialisation function:
+
+ ep93xx_register_fb(&some_board_fb_info);
+
+=====================
+Video Attribute Flags
+=====================
+
+The ep93xxfb_mach_info structure has a flags field which can be used
+to configure the controller. The video attributes flags are fully
+documented in section 7 of the EP93xx users' guide. The following
+flags are available:
+
+EP93XXFB_PCLK_FALLING Clock data on the falling edge of the
+ pixel clock. The default is to clock
+ data on the rising edge.
+
+EP93XXFB_SYNC_BLANK_HIGH Blank signal is active high. By
+ default the blank signal is active low.
+
+EP93XXFB_SYNC_HORIZ_HIGH Horizontal sync is active high. By
+ default the horizontal sync is active low.
+
+EP93XXFB_SYNC_VERT_HIGH Vertical sync is active high. By
+ default the vertical sync is active high.
+
+The physical address of the framebuffer can be controlled using the
+following flags:
+
+EP93XXFB_USE_SDCSN0 Use SDCSn[0] for the framebuffer. This
+ is the default setting.
+
+EP93XXFB_USE_SDCSN1 Use SDCSn[1] for the framebuffer.
+
+EP93XXFB_USE_SDCSN2 Use SDCSn[2] for the framebuffer.
+
+EP93XXFB_USE_SDCSN3 Use SDCSn[3] for the framebuffer.
+
+==================
+Platform callbacks
+==================
+
+The EP93xx framebuffer driver supports three optional platform
+callbacks: setup, teardown and blank. The setup and teardown functions
+are called when the framebuffer driver is installed and removed
+respectively. The blank function is called whenever the display is
+blanked or unblanked.
+
+The setup and teardown devices pass the platform_device structure as
+an argument. The fb_info and ep93xxfb_mach_info structures can be
+obtained as follows:
+
+ static int some_board_fb_setup(struct platform_device *pdev)
+ {
+ struct ep93xxfb_mach_info *mach_info = pdev->dev.platform_data;
+ struct fb_info *fb_info = platform_get_drvdata(pdev);
+
+ /* Board specific framebuffer setup */
+ }
+
+======================
+Setting the video mode
+======================
+
+The video mode is set using the following syntax:
+
+ video=XRESxYRES[-BPP][@REFRESH]
+
+If the EP93xx video driver is built-in then the video mode is set on
+the Linux kernel command line, for example:
+
+ video=ep93xx-fb:800x600-16@60
+
+If the EP93xx video driver is built as a module then the video mode is
+set when the module is installed:
+
+ modprobe ep93xx-fb video=320x240
+
+==============
+Screenpage bug
+==============
+
+At least on the EP9315 there is a silicon bug which causes bit 27 of
+the VIDSCRNPAGE (framebuffer physical offset) to be tied low. There is
+an unofficial errata for this bug at:
+ http://marc.info/?l=linux-arm-kernel&m=110061245502000&w=2
+
+By default the EP93xx framebuffer driver checks if the allocated physical
+address has bit 27 set. If it does, then the memory is freed and an
+error is returned. The check can be disabled by adding the following
+option when loading the driver:
+
+ ep93xx-fb.check_screenpage_bug=0
+
+In some cases it may be possible to reconfigure your SDRAM layout to
+avoid this bug. See section 13 of the EP93xx users' guide for details.

+The current implementation is intended for developers only: while it
+does support ordinary file operations on clients we have tested against
+(including the linux client), it is incomplete in ways which may limit
+features unexpectedly, cause known bugs in rare cases, or cause
+interoperability problems with future clients. Known issues:
+
+ - gss support is questionable: currently mounts with kerberos
+ from a linux client are possible, but we aren't really
+ conformant with the spec (for example, we don't use kerberos
+ on the backchannel correctly).
+ - no trunking support: no clients currently take advantage of
+ trunking, but this is a mandatory failure, and its use is
+ recommended to clients in a number of places. (E.g. to ensure
+ timely renewal in case an existing connection's retry timeouts
+ have gotten too long; see section 8.3 of the draft.)
+ Therefore, lack of this feature may cause future clients to
+ fail.
+ - Incomplete backchannel support: incomplete backchannel gss
+ support and no support for BACKCHANNEL_CTL mean that
+ callbacks (hence delegations and layouts) may not be
+ available and clients confused by the incomplete
+ implementation may fail.
+ - Server reboot recovery is unsupported; if the server reboots,
+ clients may fail.
+ - We do not support SSV, which provides security for shared
+ client-server state (thus preventing unauthorized tampering
+ with locks and opens, for example). It is mandatory for
+ servers to support this, though no clients use it yet.
+ - Mandatory operations which we do not support, such as
+ DESTROY_CLIENTID, FREE_STATEID, SECINFO_NO_NAME, and
+ TEST_STATEID, are not currently used by clients, but will be
+ (and the spec recommends their uses in common cases), and
+ clients should not be expected to know how to recover from the
+ case where they are not supported. This will eventually cause
+ interoperability failures.
+
+In addition, some limitations are inherited from the current NFSv4
+implementation:
+
+ - Incomplete delegation enforcement: if a file is renamed or
+ unlinked, a client holding a delegation may continue to
+ indefinitely allow opens of the file under the old name.

+Kernel driver power_meter
+=========================
+
+This driver talks to ACPI 4.0 power meters.
+
+Supported systems:
+ * Any recent system with ACPI 4.0.
+ Prefix: 'power_meter'
+ Datasheet: http://acpi.info/, section 10.4.
+
+Author: Darrick J. Wong
+
+Description
+-----------
+
+This driver implements sensor reading support for the power meters exposed in
+the ACPI 4.0 spec (Chapter 10.4). These devices have a simple set of
+features--a power meter that returns average power use over a configurable
+interval, an optional capping mechanism, and a couple of trip points. The
+sysfs interface conforms with the specification outlined in the "Power" section
+of Documentation/hwmon/sysfs-interface.
+
+Special Features
+----------------
+
+The power[1-*]_is_battery knob indicates if the power supply is a battery.
+Both power[1-*]_average_{min,max} must be set before the trip points will work.
+When both of them are set, an ACPI event will be broadcast on the ACPI netlink
+socket and a poll notification will be sent to the appropriate
+power[1-*]_average sysfs file.
+
+The power[1-*]_{model_number, serial_number, oem_info} fields display arbitrary
+strings that ACPI provides with the meter. The measures/ directory contains
+symlinks to the devices that this meter measures.
+
+Some computers have the ability to enforce a power cap in hardware. If this is
+the case, the power[1-*]_cap and related sysfs files will appear. When the
+average power consumption exceeds the cap, an ACPI event will be broadcast on
+the netlink event socket and a poll notification will be sent to the
+appropriate power[1-*]_alarm file to indicate that capping has begun, and the
+hardware has taken action to reduce power consumption. Most likely this will
+result in reduced performance.
+
+There are a few other ACPI notifications that can be sent by the firmware. In
+all cases the ACPI event will be broadcast on the ACPI netlink event socket as
+well as sent as a poll notification to a sysfs file. The events are as
+follows:
+
+power[1-*]_cap will be notified if the firmware changes the power cap.
+power[1-*]_interval will be notified if the firmware changes the averaging
+interval.

-====================

- Prefix: 'fscher'
- Addresses scanned: I2C 0x73
-
-Authors:
- Reinhard Nissl <rnissl@gmx.de> based on work

-
-Description
------------
-
-This driver implements support for the Fujitsu-Siemens Hermes chip. It is
-described in the 'Register Set Specification BMC Hermes based Systemboard'
-from Fujitsu-Siemens.
-
-The Hermes chip implements a hardware-based system management, e.g. for
-controlling fan speed and core voltage. There is also a watchdog counter on
-the chip which can trigger an alarm and even shut the system down.
-
-The chip provides three temperature values (CPU, motherboard and
-auxiliary), three voltage values (+12V, +5V and battery) and three fans
-(power supply, CPU and auxiliary).
-
-Temperatures are measured in degrees Celsius. The resolution is 1 degree.
-
-Fan rotation speeds are reported in RPM (rotations per minute). The value
-can be divided by a programmable divider (1, 2 or 4) which is stored on
-the chip.
-
-Voltage sensors (also known as "in" sensors) report their values in volts.
-
-All values are reported as final values from the driver. There is no need
-for further calculations.
-
-
-Detailed description
---------------------
-
-Below you'll find a single line description of all the bit values. With
-this information, you're able to decode e. g. alarms, wdog, etc. To make
-use of the watchdog, you'll need to set the watchdog time and enable the
-watchdog. After that it is necessary to restart the watchdog time within
-the specified period of time, or a system reset will occur.

-Limitations
------------
-
-* Measuring fan speed
-It seems that the chip counts "ripples" (typical fans produce 2 ripples per
-rotation while VERAX fans produce 18) in a 9-bit register. This register is
-read out every second, then the ripple prescaler (2, 4 or 8) is applied and
-the result is stored in the 8 bit output register. Due to the limitation of
-the counting register to 9 bits, it is impossible to measure a VERAX fan
-properly (even with a prescaler of 8). At its maximum speed of 3500 RPM the

-
-Author: Ben Gardner <bgardner@wabtec.com>
-
-
-Description
------------
-
-The Philips PCA9539 is a 16 bit low power I/O device.
-All 16 lines can be individually configured as an input or output.
-The input sense can also be inverted.
-The 16 lines are split between two bytes.
-
-
-Detection
----------
-
-The PCA9539 is difficult to detect and not commonly found in PC machines,
-so you have to pass the I2C bus and address of the installed PCA9539
-devices explicitly to the driver at load time via the force=... parameter.
-
-
-Sysfs entries
--------------
-
-Each is a byte that maps to the 8 I/O bits.
-A '0' suffix is for bits 0-7, while '1' is for bits 8-15.
-
-input[01] - read the current value
-output[01] - sets the output value
-direction[01] - direction of each bit: 1=input, 0=output
-invert[01] - toggle the input bit sense
-
-input reads the actual state of the line and is always available.
-The direction defaults to input for all channels.
-
-
-General Remarks
----------------
-
-Note that each output, direction, and invert entry controls 8 lines.
-You should use the read, modify, write sequence.
-For example. to set output bit 0 of 1.
- val=$(cat output0)
- val=$(( $val | 1 ))
- echo $val > output0

-Description
------------
-The PCF8574(A) is an 8-bit I/O expander for the I2C bus produced by Philips
-Semiconductors. It is designed to provide a byte I2C interface to up to 16
-separate devices (8 x PCF8574 and 8 x PCF8574A).
-
-This device consists of a quasi-bidirectional port. Each of the eight I/Os
-can be independently used as an input or output. To setup an I/O as an
-input, you have to write a 1 to the corresponding output.
-
-For more informations see the datasheet.
-
-
-Accessing PCF8574(A) via /sys interface
--------------------------------------
-
-The PCF8574(A) is plainly impossible to detect ! Stupid chip.
-So, you have to pass the I2C bus and address of the installed PCF857A
-and PCF8574A devices explicitly to the driver at load time via the
-force=... parameter.
-
-On detection (i.e. insmod, modprobe et al.), directories are being
-created for each detected PCF8574(A):
-
-/sys/bus/i2c/devices/<0>-<1>/
-where <0> is the bus the chip was detected on (e. g. i2c-0)
-and <1> the chip address ([20..27] or [38..3f]):
-
-(example: /sys/bus/i2c/devices/1-0020/)
-
-Inside these directories, there are two files each:
-read and write (and one file with chip name).
-
-The read file is read-only. Reading gives you the current I/O input
-if the corresponding output is set as 1, otherwise the current output
-value, that is to say 0.
-
-The write file is read/write. Writing a value outputs it on the I/O
-port. Reading returns the last written value. As it is not possible
-to read this value from the chip, you need to write at least once to
-this file before you can read back from it.

-About the PCF8575 chip and the pcf8575 kernel driver
-====================================================
-
-The PCF8575 chip is produced by the following manufacturers:
-
- * Philips NXP
- http://www.nxp.com/#/pip/cb=[type=product,path=50807/41735/41850,final=PCF8575_3]|pip=[pip=PCF8575_3][0]
-
- * Texas Instruments
- http://focus.ti.com/docs/prod/folders/print/pcf8575.html
-
-
-Some vendors sell small PCB's with the PCF8575 mounted on it. You can connect
-such a board to a Linux host via e.g. an USB to I2C interface. Examples of
-PCB boards with a PCF8575:
-
- * SFE Breakout Board for PCF8575 I2C Expander by RobotShop
- http://www.robotshop.ca/home/products/robot-parts/electronics/adapters-converters/sfe-pcf8575-i2c-expander-board.html
-
- * Breakout Board for PCF8575 I2C Expander by Spark Fun Electronics
- http://www.sparkfun.com/commerce/product_info.php?products_id=8130
-
-
-Description
------------
-The PCF8575 chip is a 16-bit I/O expander for the I2C bus. Up to eight of
-these chips can be connected to the same I2C bus. You can find this
-chip on some custom designed hardware, but you won't find it on PC
-motherboards.
-
-The PCF8575 chip consists of a 16-bit quasi-bidirectional port and an I2C-bus
-interface. Each of the sixteen I/O's can be independently used as an input or
-an output. To set up an I/O pin as an input, you have to write a 1 to the
-corresponding output.
-
-For more information please see the datasheet.
-
-
-Detection
----------
-
-There is no method known to detect whether a chip on a given I2C address is
-a PCF8575 or whether it is any other I2C device, so you have to pass the I2C
-bus and address of the installed PCF8575 devices explicitly to the driver at
-load time via the force=... parameter.
-
-/sys interface
---------------
-
-For each address on which a PCF8575 chip was found or forced the following
-files will be created under /sys:
-* /sys/bus/i2c/devices/<bus>-<address>/read
-* /sys/bus/i2c/devices/<bus>-<address>/write
-where bus is the I2C bus number (0, 1, ...) and address is the four-digit
-hexadecimal representation of the 7-bit I2C address of the PCF8575
-(0020 .. 0027).
-
-The read file is read-only. Reading it will trigger an I2C read and will hence
-report the current input state for the pins configured as inputs, and the
-current output value for the pins configured as outputs.
-
-The write file is read-write. Writing a value to it will configure all pins
-as output for which the corresponding bit is zero. Reading the write file will
-return the value last written, or -EAGAIN if no value has yet been written to
-the write file.
-
-On module initialization the configuration of the chip is not changed -- the
-chip is left in the state it was already configured in through either power-up
-or through previous I2C write actions.

-includes the latest version of kmemcheck.
-
-Assuming that you've already cloned the linux-2.6.git repository, all you
-have to do is add the -tip tree as a remote, like this:
-
- $ git remote add tip git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
-
-To actually download the tree, fetch the remote:
-
- $ git fetch tip
-
-And to check out a new local branch with the kmemcheck code:
-
- $ git checkout -b kmemcheck tip/kmemcheck
-
-General instructions for the -tip tree can be found here:

+Asus Laptop Extras
+
+Version 0.1
+August 6, 2009
+
+Corentin Chary <corentincj@iksaif.net>
+http://acpi4asus.sf.net/
+
+ This driver provides support for extra features of ACPI-compatible ASUS laptops.
+ It may also support some MEDION, JVC or VICTOR laptops (such as MEDION 9675 or
+ VICTOR XP7210 for example). It makes all the extra buttons generate standard
+ ACPI events that go through /proc/acpi/events and input events (like keyboards).
+ On some models adds support for changing the display brightness and output,
+ switching the LCD backlight on and off, and most importantly, allows you to
+ blink those fancy LEDs intended for reporting mail and wireless status.
+
+This driver supercedes the old asus_acpi driver.
+
+Requirements
+------------
+
+ Kernel 2.6.X sources, configured for your computer, with ACPI support.
+ You also need CONFIG_INPUT and CONFIG_ACPI.
+
+Status
+------
+
+ The features currently supported are the following (see below for
+ detailed description):
+
+ - Fn key combinations
+ - Bluetooth enable and disable
+ - Wlan enable and disable
+ - GPS enable and disable
+ - Video output switching
+ - Ambient Light Sensor on and off
+ - LED control
+ - LED Display control
+ - LCD brightness control
+ - LCD on and off
+
+ A compatibility table by model and feature is maintained on the web
+ site, http://acpi4asus.sf.net/.
+
+Usage
+-----
+
+ Try "modprobe asus_acpi". Check your dmesg (simply type dmesg). You should
+ see some lines like this :
+
+ Asus Laptop Extras version 0.42
+ L2D model detected.
+
+ If it is not the output you have on your laptop, send it (and the laptop's
+ DSDT) to me.
+
+ That's all, now, all the events generated by the hotkeys of your laptop
+ should be reported in your /proc/acpi/event entry. You can check with
+ "acpi_listen".
+
+ Hotkeys are also reported as input keys (like keyboards) you can check
+ which key are supported using "xev" under X11.
+
+ You can get informations on the version of your DSDT table by reading the
+ /sys/devices/platform/asus-laptop/infos entry. If you have a question or a
+ bug report to do, please include the output of this entry.
+
+LEDs
+----
+
+ You can modify LEDs be echoing values to /sys/class/leds/asus::*/brightness :
+ echo 1 > /sys/class/leds/asus::mail/brightness
+ will switch the mail LED on.
+ You can also know if they are on/off by reading their content and use
+ kernel triggers like ide-disk or heartbeat.
+
+Backlight
+---------
+
+ You can control lcd backlight power and brightness with
+ /sys/class/backlight/asus-laptop/. Brightness Values are between 0 and 15.
+
+Wireless devices
+---------------
+
+ You can turn the internal Bluetooth adapter on/off with the bluetooth entry
+ (only on models with Bluetooth). This usually controls the associated LED.
+ Same for Wlan adapter.
+
+Display switching
+-----------------
+
+ Note: the display switching code is currently considered EXPERIMENTAL.
+
+ Switching works for the following models:
+ L3800C
+ A2500H
+ L5800C
+ M5200N
+ W1000N (albeit with some glitches)
+ M6700R
+ A6JC
+ F3J
+
+ Switching doesn't work for the following:
+ M3700N
+ L2X00D (locks the laptop under certain conditions)
+
+ To switch the displays, echo values from 0 to 15 to
+ /sys/devices/platform/asus-laptop/display. The significance of those values
+ is as follows:
+
+ +-------+-----+-----+-----+-----+-----+
+ | Bin | Val | DVI | TV | CRT | LCD |
+ +-------+-----+-----+-----+-----+-----+
+ + 0000 + 0 + + + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0001 + 1 + + + + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 0010 + 2 + + + X + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0011 + 3 + + + X + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 0100 + 4 + + X + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 0101 + 5 + + X + + X +

+ +-------+-----+-----+-----+-----+-----+
+ + 1001 + 9 + X + + + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 1010 + 10 + X + + X + +
+ +-------+-----+-----+-----+-----+-----+
+ + 1011 + 11 + X + + X + X +
+ +-------+-----+-----+-----+-----+-----+
+ + 1100 + 12 + X + X + + +
+ +-------+-----+-----+-----+-----+-----+
+ + 1101 + 13 + X + X + + X +
+ +-------+-----+-----+-----+-----+-----+

+ +-------+-----+-----+-----+-----+-----+
+ + 1111 + 15 + X + X + X + X +
+ +-------+-----+-----+-----+-----+-----+
+
+ In most cases, the appropriate displays must be plugged in for the above
+ combinations to work. TV-Out may need to be initialized at boot time.
+
+ Debugging:
+ 1) Check whether the Fn+F8 key:
+ a) does not lock the laptop (try disabling CONFIG_X86_UP_APIC or boot with
+ noapic / nolapic if it does)
+ b) generates events (0x6n, where n is the value corresponding to the
+ configuration above)
+ c) actually works
+ Record the disp value at every configuration.
+ 2) Echo values from 0 to 15 to /sys/devices/platform/asus-laptop/display.
+ Record its value, note any change. If nothing changes, try a broader range,
+ up to 65535.
+ 3) Send ANY output (both positive and negative reports are needed, unless your
+ machine is already listed above) to the acpi4asus-user mailing list.
+
+ Note: on some machines (e.g. L3C), after the module has been loaded, only 0x6n
+ events are generated and no actual switching occurs. In such a case, a line
+ like:
+
+ echo $((10#$arg-60)) > /sys/devices/platform/asus-laptop/display
+
+ will usually do the trick ($arg is the 0000006n-like event passed to acpid).
+
+ Note: there is currently no reliable way to read display status on xxN
+ (Centrino) models.
+
+LED display
+-----------
+
+ Some models like the W1N have a LED display that can be used to display
+ several informations.
+
+ LED display works for the following models:
+ W1000N
+ W1J
+
+ To control the LED display, use the following :
+
+ echo 0x0T000DDD > /sys/devices/platform/asus-laptop/
+
+ where T control the 3 letters display, and DDD the 3 digits display,
+ according to the tables below.
+
+ DDD (digits)
+ 000 to 999 = display digits
+ AAA = ---
+ BBB to FFF = turn-off
+
+ T (type)
+ 0 = off
+ 1 = dvd
+ 2 = vcd
+ 3 = mp3
+ 4 = cd
+ 5 = tv
+ 6 = cpu
+ 7 = vol
+
+ For example "echo 0x01000001 >/sys/devices/platform/asus-laptop/ledd"
+ would display "DVD001".
+
+Driver options:
+---------------
+
+ Options can be passed to the asus-laptop driver using the standard
+ module argument syntax (<param>=<value> when passing the option to the
+ module or asus-laptop.<param>=<value> on the kernel boot line when
+ asus-laptop is statically linked into the kernel).
+
+ wapf: WAPF defines the behavior of the Fn+Fx wlan key
+ The significance of values is yet to be found, but
+ most of the time:
+ - 0x0 should do nothing
+ - 0x1 should allow to control the device with Fn+Fx key.
+ - 0x4 should send an ACPI event (0x88) while pressing the Fn+Fx key
+ - 0x5 like 0x1 or 0x4
+
+ The default value is 0x1.
+
+Unsupported models
+------------------
+
+ These models will never be supported by this module, as they use a completely
+ different mechanism to handle LEDs and extra stuff (meaning we have no clue
+ how it works):
+
+ - ASUS A1300 (A1B), A1370D
+ - ASUS L7300G
+ - ASUS L8400
+
+Patches, Errors, Questions:
+--------------------------
+
+ I appreciate any success or failure
+ reports, especially if they add to or correct the compatibility table.
+ Please include the following information in your report:
+
+ - Asus model name
+ - a copy of your ACPI tables, using the "acpidump" utility
+ - a copy of /sys/devices/platform/asus-laptop/infos
+ - which driver features work and which don't
+ - the observed behavior of non-working features
+
+ Any other comments or patches are also more than welcome.

- Using the Linux Kernel Markers
-
- Mathieu Desnoyers
-
-
-This document introduces Linux Kernel Markers and their use. It provides
-examples of how to insert markers in the kernel and connect probe functions to
-them and provides some examples of probe functions.
-
-
-* Purpose of markers
-
-A marker placed in code provides a hook to call a function (probe) that you can
-provide at runtime. A marker can be "on" (a probe is connected to it) or "off"
-(no probe is attached). When a marker is "off" it has no effect, except for
-adding a tiny time penalty (checking a condition for a branch) and space
-penalty (adding a few bytes for the function call at the end of the
-instrumented function and adds a data structure in a separate section). When a
-marker is "on", the function you provide is called each time the marker is
-executed, in the execution context of the caller. When the function provided
-ends its execution, it returns to the caller (continuing from the marker site).
-
-You can put markers at important locations in the code. Markers are
-lightweight hooks that can pass an arbitrary number of parameters,
-described in a printk-like format string, to the attached probe function.
-
-They can be used for tracing and performance accounting.
-
-
-* Usage
-
-In order to use the macro trace_mark, you should include linux/marker.h.
-
-#include <linux/marker.h>
-
-And,
-
-trace_mark(subsystem_event, "myint %d mystring %s", someint, somestring);
-Where :
-- subsystem_event is an identifier unique to your event
- - subsystem is the name of your subsystem.
- - event is the name of the event to mark.
-- "myint %d mystring %s" is the formatted string for the serializer. "myint" and
- "mystring" are repectively the field names associated with the first and
- second parameter.
-- someint is an integer.
-- somestring is a char pointer.
-
-Connecting a function (probe) to a marker is done by providing a probe (function
-to call) for the specific marker through marker_probe_register() and can be
-activated by calling marker_arm(). Marker deactivation can be done by calling
-marker_disarm() as many times as marker_arm() has been called. Removing a probe
-is done through marker_probe_unregister(); it will disarm the probe.
-
-marker_synchronize_unregister() must be called between probe unregistration and
-the first occurrence of
-- the end of module exit function,
- to make sure there is no caller left using the probe;
-- the free of any resource used by the probes,
- to make sure the probes wont be accessing invalid data.
-This, and the fact that preemption is disabled around the probe call, make sure
-that probe removal and module unload are safe. See the "Probe example" section
-below for a sample probe module.
-
-The marker mechanism supports inserting multiple instances of the same marker.
-Markers can be put in inline functions, inlined static functions, and
-unrolled loops as well as regular functions.
-
-The naming scheme "subsystem_event" is suggested here as a convention intended
-to limit collisions. Marker names are global to the kernel: they are considered
-as being the same whether they are in the core kernel image or in modules.
-Conflicting format strings for markers with the same name will cause the markers
-to be detected to have a different format string not to be armed and will output
-a printk warning which identifies the inconsistency:
-
-"Format mismatch for probe probe_name (format), marker (format)"
-
-Another way to use markers is to simply define the marker without generating any
-function call to actually call into the marker. This is useful in combination
-with tracepoint probes in a scheme like this :
-
-void probe_tracepoint_name(unsigned int arg1, struct task_struct *tsk);
-
-DEFINE_MARKER_TP(marker_eventname, tracepoint_name, probe_tracepoint_name,
- "arg1 %u pid %d");
-
-notrace void probe_tracepoint_name(unsigned int arg1, struct task_struct *tsk)
-{
- struct marker *marker = &GET_MARKER(kernel_irq_entry);
- /* write data to trace buffers ... */
-}
-
-* Probe / marker example
-
-See the example provided in samples/markers/src
-
-Compile them with your kernel.
-
-Run, as root :
-modprobe marker-example (insmod order is not important)
-modprobe probe-example
-cat /proc/marker-example (returns an expected error)
-rmmod marker-example probe-example
-dmesg

+Regulator API design notes
+==========================
+
+This document provides a brief, partially structured, overview of some
+of the design considerations which impact the regulator API design.
+
+Safety
+------
+
+ - Errors in regulator configuration can have very serious consequences
+ for the system, potentially including lasting hardware damage.
+ - It is not possible to automatically determine the power confugration
+ of the system - software-equivalent variants of the same chip may
+ have different power requirments, and not all components with power
+ requirements are visible to software.
+
+ => The API should make no changes to the hardware state unless it has
+ specific knowledge that these changes are safe to do perform on
+ this particular system.
+
+Consumer use cases
+------------------
+
+ - The overwhelming majority of devices in a system will have no
+ requirement to do any runtime configuration of their power beyond
+ being able to turn it on or off.
+
+ - Many of the power supplies in the system will be shared between many
+ different consumers.
+
+ => The consumer API should be structured so that these use cases are
+ very easy to handle and so that consumers will work with shared
+ supplies without any additional effort.

+ Subsystem Trace Points: kmem
+
+The tracing system kmem captures events related to object and page allocation
+within the kernel. Broadly speaking there are four major subheadings.
+
+ o Slab allocation of small objects of unknown type (kmalloc)
+ o Slab allocation of small objects of known type
+ o Page allocation
+ o Per-CPU Allocator Activity
+ o External Fragmentation
+
+This document will describe what each of the tracepoints are and why they
+might be useful.
+
+1. Slab allocation of small objects of unknown type
+===================================================
+kmalloc call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s
+kmalloc_node call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
+kfree call_site=%lx ptr=%p
+
+Heavy activity for these events may indicate that a specific cache is
+justified, particularly if kmalloc slab pages are getting significantly
+internal fragmented as a result of the allocation pattern. By correlating
+kmalloc with kfree, it may be possible to identify memory leaks and where
+the allocation sites were.
+
+
+2. Slab allocation of small objects of known type
+=================================================
+kmem_cache_alloc call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s
+kmem_cache_alloc_node call_site=%lx ptr=%p bytes_req=%zu bytes_alloc=%zu gfp_flags=%s node=%d
+kmem_cache_free call_site=%lx ptr=%p
+
+These events are similar in usage to the kmalloc-related events except that
+it is likely easier to pin the event down to a specific cache. At the time
+of writing, no information is available on what slab is being allocated from,
+but the call_site can usually be used to extrapolate that information
+
+3. Page allocation
+==================
+mm_page_alloc page=%p pfn=%lu order=%d migratetype=%d gfp_flags=%s
+mm_page_alloc_zone_locked page=%p pfn=%lu order=%u migratetype=%d cpu=%d percpu_refill=%d
+mm_page_free_direct page=%p pfn=%lu order=%d
+mm_pagevec_free page=%p pfn=%lu order=%d cold=%d
+
+These four events deal with page allocation and freeing. mm_page_alloc is
+a simple indicator of page allocator activity. Pages may be allocated from
+the per-CPU allocator (high performance) or the buddy allocator.
+
+If pages are allocated directly from the buddy allocator, the
+mm_page_alloc_zone_locked event is triggered. This event is important as high
+amounts of activity imply high activity on the zone->lock. Taking this lock
+impairs performance by disabling interrupts, dirtying cache lines between
+CPUs and serialising many CPUs.
+
+When a page is freed directly by the caller, the mm_page_free_direct event
+is triggered. Significant amounts of activity here could indicate that the
+callers should be batching their activities.
+
+When pages are freed using a pagevec, the mm_pagevec_free is
+triggered. Broadly speaking, pages are taken off the LRU lock in bulk and
+freed in batch with a pagevec. Significant amounts of activity here could
+indicate that the system is under memory pressure and can also indicate
+contention on the zone->lru_lock.
+
+4. Per-CPU Allocator Activity
+=============================
+mm_page_alloc_zone_locked page=%p pfn=%lu order=%u migratetype=%d cpu=%d percpu_refill=%d
+mm_page_pcpu_drain page=%p pfn=%lu order=%d cpu=%d migratetype=%d
+
+In front of the page allocator is a per-cpu page allocator. It exists only
+for order-0 pages, reduces contention on the zone->lock and reduces the
+amount of writing on struct page.
+
+When a per-CPU list is empty or pages of the wrong type are allocated,
+the zone->lock will be taken once and the per-CPU list refilled. The event
+triggered is mm_page_alloc_zone_locked for each page allocated with the
+event indicating whether it is for a percpu_refill or not.
+
+When the per-CPU list is too full, a number of pages are freed, each one
+which triggers a mm_page_pcpu_drain event.
+
+The individual nature of the events are so that pages can be tracked
+between allocation and freeing. A number of drain or refill pages that occur
+consecutively imply the zone->lock being taken once. Large amounts of PCP
+refills and drains could imply an imbalance between CPUs where too much work
+is being concentrated in one place. It could also indicate that the per-CPU
+lists should be a larger size. Finally, large amounts of refills on one CPU
+and drains on another could be a factor in causing large amounts of cache
+line bounces due to writes between CPUs and worth investigating if pages
+can be allocated and freed on the same CPU through some algorithm change.
+
+5. External Fragmentation
+=========================
+mm_page_alloc_extfrag page=%p pfn=%lu alloc_order=%d fallback_order=%d pageblock_order=%d alloc_migratetype=%d fallback_migratetype=%d fragmenting=%d change_ownership=%d
+
+External fragmentation affects whether a high-order allocation will be
+successful or not. For some types of hardware, this is important although
+it is avoided where possible. If the system is using huge pages and needs
+to be able to resize the pool over the lifetime of the system, this value
+is important.
+
+Large numbers of this event implies that memory is fragmenting and
+high-order allocations will start failing at some time in the future. One
+means of reducing the occurange of this event is to increase the size of
+min_free_kbytes in increments of 3*pageblock_size*nr_online_nodes where
+pageblock_size is usually the size of the default hugepage size.

+ Notes on Analysing Behaviour Using Events and Tracepoints
+
+ Documentation written by Mel Gorman
+ PCL information heavily based on email from Ingo Molnar
+
+1. Introduction
+===============
+
+Tracepoints (see Documentation/trace/tracepoints.txt) can be used without
+creating custom kernel modules to register probe functions using the event
+tracing infrastructure.
+
+Simplistically, tracepoints will represent an important event that when can
+be taken in conjunction with other tracepoints to build a "Big Picture" of
+what is going on within the system. There are a large number of methods for
+gathering and interpreting these events. Lacking any current Best Practises,
+this document describes some of the methods that can be used.
+
+This document assumes that debugfs is mounted on /sys/kernel/debug and that
+the appropriate tracing options have been configured into the kernel. It is
+assumed that the PCL tool tools/perf has been installed and is in your path.
+
+2. Listing Available Events
+===========================
+
+2.1 Standard Utilities
+----------------------
+
+All possible events are visible from /sys/kernel/debug/tracing/events. Simply
+calling
+
+ $ find /sys/kernel/debug/tracing/events -type d
+
+will give a fair indication of the number of events available.
+
+2.2 PCL
+-------
+
+Discovery and enumeration of all counters and events, including tracepoints
+are available with the perf tool. Getting a list of available events is a
+simple case of
+
+ $ perf list 2>&1 | grep Tracepoint
+ ext4:ext4_free_inode [Tracepoint event]
+ ext4:ext4_request_inode [Tracepoint event]
+ ext4:ext4_allocate_inode [Tracepoint event]
+ ext4:ext4_write_begin [Tracepoint event]
+ ext4:ext4_ordered_write_end [Tracepoint event]
+ [ .... remaining output snipped .... ]
+
+
+2. Enabling Events
+==================
+
+2.1 System-Wide Event Enabling
+------------------------------
+
+See Documentation/trace/events.txt for a proper description on how events
+can be enabled system-wide. A short example of enabling all events related
+to page allocation would look something like
+
+ $ for i in `find /sys/kernel/debug/tracing/events -name "enable" | grep mm_`; do echo 1 > $i; done
+
+2.2 System-Wide Event Enabling with SystemTap
+---------------------------------------------
+
+In SystemTap, tracepoints are accessible using the kernel.trace() function
+call. The following is an example that reports every 5 seconds what processes
+were allocating the pages.
+
+ global page_allocs
+
+ probe kernel.trace("mm_page_alloc") {
+ page_allocs[execname()]++
+ }
+
+ function print_count() {
+ printf ("%-25s %-s\n", "#Pages Allocated", "Process Name")
+ foreach (proc in page_allocs-)
+ printf("%-25d %s\n", page_allocs[proc], proc)
+ printf ("\n")
+ delete page_allocs
+ }
+
+ probe timer.s(5) {
+ print_count()
+ }
+
+2.3 System-Wide Event Enabling with PCL
+---------------------------------------
+
+By specifying the -a switch and analysing sleep, the system-wide events
+for a duration of time can be examined.
+
+ $ perf stat -a \
+ -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+ -e kmem:mm_pagevec_free \
+ sleep 10
+ Performance counter stats for 'sleep 10':
+
+ 9630 kmem:mm_page_alloc
+ 2143 kmem:mm_page_free_direct
+ 7424 kmem:mm_pagevec_free
+
+ 10.002577764 seconds time elapsed
+
+Similarly, one could execute a shell and exit it as desired to get a report
+at that point.
+
+2.4 Local Event Enabling
+------------------------
+
+Documentation/trace/ftrace.txt describes how to enable events on a per-thread
+basis using set_ftrace_pid.
+
+2.5 Local Event Enablement with PCL
+-----------------------------------
+
+Events can be activate and tracked for the duration of a process on a local
+basis using PCL such as follows.
+
+ $ perf stat -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+ -e kmem:mm_pagevec_free ./hackbench 10
+ Time: 0.909
+
+ Performance counter stats for './hackbench 10':
+
+ 17803 kmem:mm_page_alloc
+ 12398 kmem:mm_page_free_direct
+ 4827 kmem:mm_pagevec_free
+
+ 0.973913387 seconds time elapsed
+
+3. Event Filtering
+==================
+
+Documentation/trace/ftrace.txt covers in-depth how to filter events in
+ftrace. Obviously using grep and awk of trace_pipe is an option as well
+as any script reading trace_pipe.
+
+4. Analysing Event Variances with PCL
+=====================================
+
+Any workload can exhibit variances between runs and it can be important
+to know what the standard deviation in. By and large, this is left to the
+performance analyst to do it by hand. In the event that the discrete event
+occurrences are useful to the performance analyst, then perf can be used.
+
+ $ perf stat --repeat 5 -e kmem:mm_page_alloc -e kmem:mm_page_free_direct
+ -e kmem:mm_pagevec_free ./hackbench 10
+ Time: 0.890
+ Time: 0.895
+ Time: 0.915
+ Time: 1.001
+ Time: 0.899
+
+ Performance counter stats for './hackbench 10' (5 runs):
+
+ 16630 kmem:mm_page_alloc ( +- 3.542% )
+ 11486 kmem:mm_page_free_direct ( +- 4.771% )
+ 4730 kmem:mm_pagevec_free ( +- 2.325% )
+
+ 0.982653002 seconds time elapsed ( +- 1.448% )
+
+In the event that some higher-level event is required that depends on some
+aggregation of discrete events, then a script would need to be developed.
+
+Using --repeat, it is also possible to view how events are fluctuating over
+time on a system wide basis using -a and sleep.
+
+ $ perf stat -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+ -e kmem:mm_pagevec_free \
+ -a --repeat 10 \
+ sleep 1
+ Performance counter stats for 'sleep 1' (10 runs):
+
+ 1066 kmem:mm_page_alloc ( +- 26.148% )
+ 182 kmem:mm_page_free_direct ( +- 5.464% )
+ 890 kmem:mm_pagevec_free ( +- 30.079% )
+
+ 1.002251757 seconds time elapsed ( +- 0.005% )
+
+5. Higher-Level Analysis with Helper Scripts
+============================================
+
+When events are enabled the events that are triggering can be read from
+/sys/kernel/debug/tracing/trace_pipe in human-readable format although binary
+options exist as well. By post-processing the output, further information can
+be gathered on-line as appropriate. Examples of post-processing might include
+

+6. Lower-Level Analysis with PCL
+================================
+
+There may also be a requirement to identify what functions with a program
+were generating events within the kernel. To begin this sort of analysis, the
+data must be recorded. At the time of writing, this required root
+
+ $ perf record -c 1 \
+ -e kmem:mm_page_alloc -e kmem:mm_page_free_direct \
+ -e kmem:mm_pagevec_free \
+ ./hackbench 10
+ Time: 0.894
+ [ perf record: Captured and wrote 0.733 MB perf.data (~32010 samples) ]
+
+Note the use of '-c 1' to set the event period to sample. The default sample
+period is quite high to minimise overhead but the information collected can be
+very coarse as a result.
+
+This record outputted a file called perf.data which can be analysed using
+perf report.

+VIDIOC_S_CROP and VIDIOC_S_FMT behaviour
+----------------------------------------
+
+Above user ioctls modify image geometry as follows:
+
+VIDIOC_S_CROP: sets location and sizes of the sensor window. Unit is one sensor
+pixel. Changing sensor window sizes preserves any scaling factors, therefore
+user window sizes change as well.
+
+VIDIOC_S_FMT: sets user window. Should preserve previously set sensor window as
+much as possible by modifying scaling factors. If the sensor window cannot be
+preserved precisely, it may be changed too.
+
+In soc-camera there are two locations, where scaling and cropping can taks
+place: in the camera driver and in the host driver. User ioctls are first passed
+to the host driver, which then generally passes them down to the camera driver.
+It is more efficient to perform scaling and cropping in the camera driver to
+save camera bus bandwidth and maximise the framerate. However, if the camera
+driver failed to set the required parameters with sufficient precision, the host
+driver may decide to also use its own scaling and cropping to fulfill the user's
+request.
+
+Camera drivers are interfaced to the soc-camera core and to host drivers over
+the v4l2-subdev API, which is completely functional, it doesn't pass any data.
+Therefore all camera drivers shall reply to .g_fmt() requests with their current
+output geometry. This is necessary to correctly configure the camera bus.
+.s_fmt() and .try_fmt() have to be implemented too. Sensor window and scaling
+factors have to be maintained by camera drivers internally. According to the
+V4L2 API all capture drivers must support the VIDIOC_CROPCAP ioctl, hence we
+rely on camera drivers implementing .cropcap(). If the camera driver does not
+support cropping, it may choose to not implement .s_crop(), but to enable
+cropping support by the camera host driver at least the .g_crop method must be
+implemented.
+
+User window geometry is kept in .user_width and .user_height fields in struct
+soc_camera_device and used by the soc-camera core and host drivers. The core
+updates these fields upon successful completion of a .s_fmt() call, but if these
+fields change elsewhere, e.g., during .s_crop() processing, the host driver is
+responsible for updating them.

+How to use the Kernel Samepage Merging feature
+----------------------------------------------
+
+KSM is a memory-saving de-duplication feature, enabled by CONFIG_KSM=y,
+added to the Linux kernel in 2.6.32. See mm/ksm.c for its implementation,
+and http://lwn.net/Articles/306704/ and http://lwn.net/Articles/330589/
+
+The KSM daemon ksmd periodically scans those areas of user memory which
+have been registered with it, looking for pages of identical content which
+can be replaced by a single write-protected page (which is automatically
+copied if a process later wants to update its content).
+
+KSM was originally developed for use with KVM (where it was known as
+Kernel Shared Memory), to fit more virtual machines into physical memory,
+by sharing the data common between them. But it can be useful to any
+application which generates many instances of the same data.
+
+KSM only merges anonymous (private) pages, never pagecache (file) pages.
+KSM's merged pages are at present locked into kernel memory for as long
+as they are shared: so cannot be swapped out like the user pages they
+replace (but swapping KSM pages should follow soon in a later release).
+
+KSM only operates on those areas of address space which an application
+has advised to be likely candidates for merging, by using the madvise(2)
+system call: int madvise(addr, length, MADV_MERGEABLE).
+
+The app may call int madvise(addr, length, MADV_UNMERGEABLE) to cancel
+that advice and restore unshared pages: whereupon KSM unmerges whatever
+it merged in that range. Note: this unmerging call may suddenly require
+more memory than is available - possibly failing with EAGAIN, but more
+probably arousing the Out-Of-Memory killer.
+
+If KSM is not configured into the running kernel, madvise MADV_MERGEABLE
+and MADV_UNMERGEABLE simply fail with EINVAL. If the running kernel was
+built with CONFIG_KSM=y, those calls will normally succeed: even if the
+the KSM daemon is not currently running, MADV_MERGEABLE still registers
+the range for whenever the KSM daemon is started; even if the range
+cannot contain any pages which KSM could actually merge; even if
+MADV_UNMERGEABLE is applied to a range which was never MADV_MERGEABLE.
+
+Like other madvise calls, they are intended for use on mapped areas of
+the user address space: they will report ENOMEM if the specified range
+includes unmapped gaps (though working on the intervening mapped areas),
+and might fail with EAGAIN if not enough memory for internal structures.
+
+Applications should be considerate in their use of MADV_MERGEABLE,
+restricting its use to areas likely to benefit. KSM's scans may use
+a lot of processing power, and its kernel-resident pages are a limited
+resource. Some installations will disable KSM for these reasons.
+
+The KSM daemon is controlled by sysfs files in /sys/kernel/mm/ksm/,
+readable by all but writable only by root:
+
+max_kernel_pages - set to maximum number of kernel pages that KSM may use
+ e.g. "echo 2000 > /sys/kernel/mm/ksm/max_kernel_pages"
+ Value 0 imposes no limit on the kernel pages KSM may use;
+ but note that any process using MADV_MERGEABLE can cause
+ KSM to allocate these pages, unswappable until it exits.
+ Default: 2000 (chosen for demonstration purposes)
+
+pages_to_scan - how many present pages to scan before ksmd goes to sleep
+ e.g. "echo 200 > /sys/kernel/mm/ksm/pages_to_scan"
+ Default: 200 (chosen for demonstration purposes)
+
+sleep_millisecs - how many milliseconds ksmd should sleep before next scan
+ e.g. "echo 20 > /sys/kernel/mm/ksm/sleep_millisecs"
+ Default: 20 (chosen for demonstration purposes)
+
+run - set 0 to stop ksmd from running but keep merged pages,
+ set 1 to run ksmd e.g. "echo 1 > /sys/kernel/mm/ksm/run",
+ set 2 to stop ksmd and unmerge all pages currently merged,
+ but leave mergeable areas registered for next run
+ Default: 1 (for immediate use by apps which register)
+
+The effectiveness of KSM and MADV_MERGEABLE is shown in /sys/kernel/mm/ksm/:
+
+pages_shared - how many shared unswappable kernel pages KSM is using
+pages_sharing - how many more sites are sharing them i.e. how much saved
+pages_unshared - how many pages unique but repeatedly checked for merging
+pages_volatile - how many pages changing too fast to be placed in a tree
+full_scans - how many times all mergeable areas have been scanned
+
+A high ratio of pages_sharing to pages_shared indicates good sharing, but
+a high ratio of pages_unshared to pages_sharing indicates wasted effort.
+pages_volatile embraces several different kinds of activity, but a high
+proportion there would also indicate poor use of madvise MADV_MERGEABLE.

+ * omap_device implementation
+ *
+ * Copyright (C) 2009 Nokia Corporation

+ *
+ * Developed in collaboration with (alphabetical order): Benoit
+ * Cousson, Kevin Hilman, Tony Lindgren, Rajendra Nayak, Vikram
+ * Pandita, Sakari Poussa, Anand Sawant, Santosh Shilimkar, Richard
+ * Woodruff
+ *
+ * This program is free software; you can redistribute it and/or modify

+ *
+ * This code provides a consistent interface for OMAP device drivers
+ * to control power management and interconnect properties of their
+ * devices.
+ *
+ * In the medium- to long-term, this code should either be
+ * a) implemented via arch-specific pointers in platform_data
+ * or
+ * b) implemented as a proper omap_bus/omap_device in Linux, no more
+ * platform_data func pointers
+ *
+ *
+ * Guidelines for usage by driver authors:
+ *
+ * 1. These functions are intended to be used by device drivers via
+ * function pointers in struct platform_data. As an example,
+ * omap_device_enable() should be passed to the driver as
+ *
+ * struct foo_driver_platform_data {
+ * ...
+ * int (*device_enable)(struct platform_device *pdev);
+ * ...
+ * }
+ *
+ * Note that the generic "device_enable" name is used, rather than
+ * "omap_device_enable". This is so other architectures can pass in their
+ * own enable/disable functions here.
+ *
+ * This should be populated during device setup:
+ *
+ * ...
+ * pdata->device_enable = omap_device_enable;
+ * ...
+ *
+ * 2. Drivers should first check to ensure the function pointer is not null
+ * before calling it, as in:
+ *
+ * if (pdata->device_enable)
+ * pdata->device_enable(pdev);
+ *
+ * This allows other architectures that don't use similar device_enable()/
+ * device_shutdown() functions to execute normally.
+ *
+ * ...
+ *
+ * Suggested usage by device drivers:
+ *
+ * During device initialization:
+ * device_enable()
+ *
+ * During device idle:
+ * (save remaining device context if necessary)
+ * device_idle();
+ *
+ * During device resume:
+ * device_enable();
+ * (restore context if necessary)
+ *
+ * During device shutdown:
+ * device_shutdown()
+ * (device must be reinitialized at this point to use it again)
+ *

- Tight version of memset for the case of just clearing a page. It turns out
- that having the alloco's spaced out slightly due to the increment/branch
- pair causes them to contend less for access to the cache. Similarly,
- keeping the stores apart from the allocos causes less contention. => Do two
- separate loops. Do multiple stores per loop to amortise the
- increment/branch cost a little.
-
- Parameters:
- r2 : source effective address (start of page)
-
- Always clears 4096 bytes.

- *
- * Revision 1.30 1994/11/16 04:28:05 bentson
- * Fix from Corey Minyard, Internet: minyard@metronet.com,
- * UUCP: minyard@wf-rch.cirr.com, WORK: minyardbnr.ca, to

- *
- * Revision 1.28 1994/11/04 00:13:16 root
- * turn off diagnostic messages
- *
- * Revision 1.27 1994/11/03 23:46:37 root
- * bunch of changes to bring driver into greater conformance
- * with the serial.c driver (looking for missed fixes)
- *
- * Revision 1.26 1994/11/03 22:40:36 root
- * automatic interrupt probing fixed.
- *
- * Revision 1.25 1994/11/03 20:17:02 root
- * start to implement auto-irq
- *
- * Revision 1.24 1994/11/03 18:01:55 root
- * still working on modem signals--trying not to drop DTR
- * during the getty/login processes
- *
- * Revision 1.23 1994/11/03 17:51:36 root
- * extend baud rate support; set receive threshold as function
- * of baud rate; fix some problems with RTS/CTS;
- *
- * Revision 1.22 1994/11/02 18:05:35 root
- * changed arguments to udelay to type long to get
- * delays to be of correct duration
- *
- * Revision 1.21 1994/11/02 17:37:30 root
- * employ udelay (after calibrating loops_per_second earlier
- * in init/main.c) instead of using home-grown delay routines
- *
- * Revision 1.20 1994/11/02 03:11:38 root
- * cy_chars_in_buffer forces a return value of 0 to let
- * login work (don't know why it does); some functions
- * that were returning EFAULT, now executes the code;
- * more work on deciding when to disable xmit interrupts;
- *
- * Revision 1.19 1994/11/01 20:10:14 root
- * define routine to start transmission interrupts (by enabling
- * transmit interrupts); directly enable/disable modem interrupts;
- *
- * Revision 1.18 1994/11/01 18:40:45 bentson
- * Don't always enable transmit interrupts in startup; interrupt on
- * TxMpty instead of TxRdy to help characters get out before shutdown;
- * restructure xmit interrupt to check for chars first and quit if
- * none are ready to go; modem status (MXVRx) is upright, _not_ inverted
- * (to my view);
- *
- * Revision 1.17 1994/10/30 04:39:45 bentson
- * rename serial_driver and callout_driver to cy_serial_driver and
- * cy_callout_driver to avoid linkage interference; initialize
- * info->type to PORT_CIRRUS; ruggedize paranoia test; elide ->port
- * from cyclades_port structure; add paranoia check to cy_close;
- *
- * Revision 1.16 1994/10/30 01:14:33 bentson
- * change major numbers; add some _early_ return statements;
- *
- * Revision 1.15 1994/10/29 06:43:15 bentson
- * final tidying up for clean compile; enable some error reporting
- *
- * Revision 1.14 1994/10/28 20:30:22 Bentson
- * lots of changes to drag the driver towards the new tty_io
- * structures and operation. not expected to work, but may
- * compile cleanly.
- *
- * Revision 1.13 1994/07/21 23:08:57 Bentson
- * add some diagnostic cruft; support 24 lines (for testing
- * both -8Y and -16Y cards; be more thorough in servicing all
- * chips during interrupt; add "volatile" a few places to
- * circumvent compiler optimizations; fix base & offset
- * computations in block_til_ready (was causing chip 0 to
- * stop operation)
- *
- * Revision 1.12 1994/07/19 16:42:11 Bentson
- * add some hackery for kernel version 1.1.8; expand
- * error messages; refine timing for delay loops and
- * declare loop params volatile
- *
- * Revision 1.11 1994/06/11 21:53:10 bentson
- * get use of save_car right in transmit interrupt service
- *
- * Revision 1.10.1.1 1994/06/11 21:31:18 bentson
- * add some diagnostic printing; try to fix save_car stuff
- *
- * Revision 1.10 1994/06/11 20:36:08 bentson
- * clean up compiler warnings
- *
- * Revision 1.9 1994/06/11 19:42:46 bentson
- * added a bunch of code to support modem signalling
- *
- * Revision 1.8 1994/06/11 17:57:07 bentson
- * recognize break & parity error
- *
- * Revision 1.7 1994/06/05 05:51:34 bentson
- * Reorder baud table to be monotonic; add cli to CP; discard
- * incoming characters and status if the line isn't open; start to
- * fold code into cy_throttle; start to port get_serial_info,
- * set_serial_info, get_modem_info, set_modem_info, and send_break
- * from serial.c; expand cy_ioctl; relocate and expand config_setup;
- * get flow control characters from tty struct; invalidate ports w/o
- * hardware;
- *
- * Revision 1.6 1994/05/31 18:42:21 bentson
- * add a loop-breaker in the interrupt service routine;
- * note when port is initialized so that it can be shut
- * down under the right conditions; receive works without
- * any obvious errors

- * transmit works without obvious errors
- *
- * Revision 1.4 1994/05/27 18:46:27 bentson

- *
- * Revision 1.3 1994/05/25 22:12:44 bentson
- * shifting from multi-port on a card to proper multiplexor
- * data structures; added skeletons of most routines

+ * Concepts and ideas behind the menu governor
+ *
+ * For the menu governor, there are 3 decision factors for picking a C
+ * state:
+ * 1) Energy break even point
+ * 2) Performance impact
+ * 3) Latency tolerance (from pmqos infrastructure)
+ * These these three factors are treated independently.
+ *
+ * Energy break even point
+ * -----------------------
+ * C state entry and exit have an energy cost, and a certain amount of time in
+ * the C state is required to actually break even on this cost. CPUIDLE
+ * provides us this duration in the "target_residency" field. So all that we
+ * need is a good prediction of how long we'll be idle. Like the traditional
+ * menu governor, we start with the actual known "next timer event" time.
+ *
+ * Since there are other source of wakeups (interrupts for example) than
+ * the next timer event, this estimation is rather optimistic. To get a
+ * more realistic estimate, a correction factor is applied to the estimate,
+ * that is based on historic behavior. For example, if in the past the actual
+ * duration always was 50% of the next timer tick, the correction factor will
+ * be 0.5.
+ *
+ * menu uses a running average for this correction factor, however it uses a
+ * set of factors, not just a single factor. This stems from the realization
+ * that the ratio is dependent on the order of magnitude of the expected
+ * duration; if we expect 500 milliseconds of idle time the likelihood of
+ * getting an interrupt very early is much higher than if we expect 50 micro
+ * seconds of idle time. A second independent factor that has big impact on
+ * the actual factor is if there is (disk) IO outstanding or not.
+ * (as a special twist, we consider every sleep longer than 50 milliseconds
+ * as perfect; there are no power gains for sleeping longer than this)
+ *
+ * For these two reasons we keep an array of 12 independent factors, that gets
+ * indexed based on the magnitude of the expected duration as well as the
+ * "is IO outstanding" property.
+ *
+ * Limiting Performance Impact
+ * ---------------------------
+ * C states, especially those with large exit latencies, can have a real
+ * noticable impact on workloads, which is not acceptable for most sysadmins,
+ * and in addition, less performance has a power price of its own.
+ *
+ * As a general rule of thumb, menu assumes that the following heuristic
+ * holds:
+ * The busier the system, the less impact of C states is acceptable
+ *
+ * This rule-of-thumb is implemented using a performance-multiplier:
+ * If the exit latency times the performance multiplier is longer than
+ * the predicted duration, the C state is not considered a candidate
+ * for selection due to a too high performance impact. So the higher
+ * this multiplier is, the longer we need to be idle to pick a deep C
+ * state, and thus the less likely a busy CPU will hit such a deep
+ * C state.
+ *
+ * Two factors are used in determing this multiplier:
+ * a value of 10 is added for each point of "per cpu load average" we have.
+ * a value of 5 points is added for each process that is waiting for
+ * IO on this CPU.
+ * (these values are experimentally determined)
+ *
+ * The load average factor gives a longer term (few seconds) input to the
+ * decision, while the iowait value gives a cpu local instantanious input.
+ * The iowait factor may look low, but realize that this is also already
+ * represented in the system load average.

+config GPIO_UCB1400
+ bool "Philips UCB1400 GPIO"
+ depends on UCB1400_CORE
+ help
+ This enables support for the Philips UCB1400 GPIO pins.
+ The UCB1400 is an AC97 audio codec.
+
+ To compile this driver as a module, choose M here: the
+ module will be called ucb1400_gpio.

+ *
+ * Written using:
+ * o Winbond WPCD376I datasheet helpfully provided by Jesse Barnes at Intel
+ * o NatSemi PC87338/PC97338 datasheet (for the serial port stuff)
+ * o DSDT dumps
+ *
+ * Supported features:
+ * o RC6
+ * o Wake-On-CIR functionality
+ *
+ * To do:
+ * o Test NEC and RC5
+ *
+ * Left as an exercise for the reader:
+ * o Learning (I have neither the hardware, nor the need)
+ * o IR Transmit (ibid)

+ * CCDC hardware module for DM355
+ * ------------------------------
+ *
+ * This module is for configuring DM355 CCD controller of VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application include dm355_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters
+ *
+ * TODO: 1) Raw bayer parameter settings and bayer capture
+ * 2) Split module parameter structure to module specific ioctl structs
+ * 3) add support for lense shading correction
+ * 4) investigate if enum used for user space type definition
+ * to be replaced by #defines or integer

+ * CCDC hardware module for DM6446
+ * ------------------------------
+ *
+ * This module is for configuring CCD controller of DM6446 VPFE to capture
+ * Raw yuv or Bayer RGB data from a decoder. CCDC has several modules
+ * such as Defect Pixel Correction, Color Space Conversion etc to
+ * pre-process the Raw Bayer RGB data, before writing it to SDRAM. This
+ * module also allows application to configure individual
+ * module parameters through VPFE_CMD_S_CCDC_RAW_PARAMS IOCTL.
+ * To do so, application includes dm644x_ccdc.h and vpfe_capture.h header
+ * files. The setparams() API is called by vpfe_capture driver
+ * to configure module parameters. This file is named DM644x so that other
+ * variants such DM6443 may be supported using the same module.
+ *
+ * TODO: Test Raw bayer parameter settings and bayer capture
+ * Split module parameter structure to module specific ioctl structs
+ * investigate if enum used for user space type definition
+ * to be replaced by #defines or integer
+ */

+ *
+ * Driver name : VPFE Capture driver
+ * VPFE Capture driver allows applications to capture and stream video
+ * frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
+ * TVP5146 or Raw Bayer RGB image data from an image sensor
+ * such as Microns' MT9T001, MT9T031 etc.
+ *
+ * These SoCs have, in common, a Video Processing Subsystem (VPSS) that
+ * consists of a Video Processing Front End (VPFE) for capturing
+ * video/raw image data and Video Processing Back End (VPBE) for displaying
+ * YUV data through an in-built analog encoder or Digital LCD port. This
+ * driver is for capture through VPFE. A typical EVM using these SoCs have
+ * following high level configuration.
+ *
+ *
+ * decoder(TVP5146/ YUV/
+ * MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
+ * data input | |
+ * V |
+ * SDRAM |
+ * V
+ * Image Processor
+ * |
+ * V
+ * SDRAM
+ * The data flow happens from a decoder connected to the VPFE over a
+ * YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
+ * and to the input of VPFE through an optional MUX (if more inputs are
+ * to be interfaced on the EVM). The input data is first passed through
+ * CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
+ * does very little or no processing on YUV data and does pre-process Raw
+ * Bayer RGB data through modules such as Defect Pixel Correction (DFC)
+ * Color Space Conversion (CSC), data gain/offset etc. After this, data
+ * can be written to SDRAM or can be connected to the image processing
+ * block such as IPIPE (on DM355 only).
+ *
+ * Features supported
+ * - MMAP IO
+ * - Capture using TVP5146 over BT.656
+ * - support for interfacing decoders using sub device model
+ * - Work with DM355 or DM6446 CCDC to do Raw Bayer RGB/YUV
+ * data capture to SDRAM.
+ * TODO list
+ * - Support multiple REQBUF after open
+ * - Support for de-allocating buffers through REQBUF
+ * - Support for Raw Bayer RGB capture
+ * - Support for chaining Image Processor
+ * - Support for static allocation of buffers
+ * - Support for USERPTR IO
+ * - Support for STREAMON before QBUF
+ * - Support for control ioctls

+ ---help---
+ The Simple Firmware Interface (SFI) provides a lightweight method
+ for platform firmware to pass information to the operating system
+ via static tables in memory. Kernel SFI support is required to
+ boot on SFI-only platforms. Currently, all SFI-only platforms are
+ based on the 2nd generation Intel Atom processor platform,
+ code-named Moorestown.
+
+ For more information, see http://simplefirmware.org
+
+ Say 'Y' here to enable the kernel to boot on SFI-only platforms.

- Say Y here if you have more than one (supported) Matrox device in
- your computer and you want to use all of them for different monitors
- ("multihead"). If you have only one device, you should say N because
- the driver compiled with Y is larger and a bit slower, especially on
- ia32 (ix86).
-
- If you said M to "Matrox unified accelerated driver" and N here, you
- will still be able to use several Matrox devices simultaneously:
- insert several instances of the module matroxfb into the kernel
- with insmod, supplying the parameter "dev=N" where N is 0, 1, etc.
- for the different Matrox devices. This method is slightly faster but
- uses 40 KB of kernel memory per Matrox card.
-
- There is no need for enabling 'Matrox multihead support' if you have
- only one Matrox card in the box.

- * inode has 'I_LOCK' flag in this case. At "normal" work-paths 'i_mutex' is
- * locked in '->writepage', e.g. in "sys_write -> alloc_pages -> direct reclaim
- * path'. So, in '->writepage()' we are only guaranteed that the page is

* Cpumasks provide a bitmap suitable for representing the

- *
- * The new cpumask_ ops take a "struct cpumask *"; the old ones
- * use cpumask_t.
- *
- * See detailed comments in the file linux/bitmap.h describing the
- * data type on which these cpumasks are based.
- *
- * For details of cpumask_scnprintf() and cpumask_parse_user(),

- * For details of cpus_remap(), see bitmap_remap in lib/bitmap.c.

- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- * Note: The alternate operations with the suffix "_nr" are used
- * to limit the range of the loop to nr_cpu_ids instead of
- * NR_CPUS when NR_CPUS > 64 for performance reasons.
- * If NR_CPUS is <= 64 then most assembler bitmask
- * operators execute faster with a constant range, so
- * the operator will continue to use NR_CPUS.
- *
- * Another consideration is that nr_cpu_ids is initialized
- * to NR_CPUS and isn't lowered until the possible cpus are
- * discovered (including any disabled cpus). So early uses
- * will span the entire range of NR_CPUS.
- * . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
- *
- * The obsolescent cpumask operations are:
- *
- * void cpu_set(cpu, mask) turn on bit 'cpu' in mask
- * void cpu_clear(cpu, mask) turn off bit 'cpu' in mask
- * void cpus_setall(mask) set all bits
- * void cpus_clear(mask) clear all bits
- * int cpu_isset(cpu, mask) true iff bit 'cpu' set in mask
- * int cpu_test_and_set(cpu, mask) test and set bit 'cpu' in mask
- *

- * (can be used as an lvalue)
- * CPU_MASK_ALL Initializer - all bits set
- * CPU_MASK_NONE Initializer - no bits set
- * unsigned long *cpus_addr(mask) Array of unsigned long's in mask
- *
- * CPUMASK_ALLOC kmalloc's a structure that is a composite of many cpumask_t
- * variables, and CPUMASK_PTR provides pointers to each field.
- *
- * The structure should be defined something like this:
- * struct my_cpumasks {
- * cpumask_t mask1;
- * cpumask_t mask2;
- * };
- *
- * Usage is then:
- * CPUMASK_ALLOC(my_cpumasks);
- * CPUMASK_PTR(mask1, my_cpumasks);
- * CPUMASK_PTR(mask2, my_cpumasks);
- *
- * --- DO NOT reference cpumask_t pointers until this check ---

- * Some device might be higher priority, or have various "hard" access
- * time requirements, for example.

+ * This primitive provides the guarantees made by the (now removed)

+ * In "classic RCU", these two guarantees happen to be one and

+ * A few notes about the KSM scanning process,
+ * to make it easier to understand the data structures below:
+ *
+ * In order to reduce excessive scanning, KSM sorts the memory pages by their
+ * contents into a data structure that holds pointers to the pages' locations.
+ *
+ * Since the contents of the pages may change at any moment, KSM cannot just
+ * insert the pages into a normal sorted tree and expect it to find anything.
+ * Therefore KSM uses two data structures - the stable and the unstable tree.
+ *
+ * The stable tree holds pointers to all the merged pages (ksm pages), sorted
+ * by their contents. Because each such page is write-protected, searching on
+ * this tree is fully assured to be working (except when pages are unmapped),
+ * and therefore this tree is called the stable tree.
+ *
+ * In addition to the stable tree, KSM uses a second data structure called the
+ * unstable tree: this tree holds pointers to pages which have been found to
+ * be "unchanged for a period of time". The unstable tree sorts these pages
+ * by their contents, but since they are not write-protected, KSM cannot rely
+ * upon the unstable tree to work correctly - the unstable tree is liable to
+ * be corrupted as its contents are modified, and so it is called unstable.
+ *
+ * KSM solves this problem by several techniques:
+ *
+ * 1) The unstable tree is flushed every time KSM completes scanning all
+ * memory areas, and then the tree is rebuilt again from the beginning.
+ * 2) KSM will only insert into the unstable tree, pages whose hash value
+ * has not changed since the previous scan of all memory areas.
+ * 3) The unstable tree is a RedBlack Tree - so its balancing is based on the
+ * colors of the nodes and not on their contents, assuring that even when
+ * the tree gets "corrupted" it won't get out of balance, so scanning time
+ * remains the same (also, searching and inserting nodes in an rbtree uses
+ * the same algorithm, so we have no overhead when we flush and rebuild).
+ * 4) KSM never flushes the stable tree, which means that even if it were to
+ * take 10 attempts to find a page in the unstable tree, once it is found,
+ * it is secured in the stable tree. (When we scan a new page, we first
+ * compare it against the stable tree, and then against the unstable tree.)

+ *
+ * There's one open issue:
+ *
+ * The EIO will be only reported on the next IO
+ * operation and then cleared through the IO map.
+ * Normally Linux has two mechanisms to pass IO error
+ * first through the AS_EIO flag in the address space
+ * and then through the PageError flag in the page.
+ * Since we drop pages on memory failure handling the
+ * only mechanism open to use is through AS_AIO.
+ *
+ * This has the disadvantage that it gets cleared on
+ * the first operation that returns an error, while
+ * the PageError bit is more sticky and only cleared
+ * when the page is reread or dropped. If an
+ * application assumes it will always get error on
+ * fsync, but does other operations on the fd before
+ * and the page is dropped inbetween then the error
+ * will not be properly reported.
+ *
+ * This can already happen even without hwpoisoned
+ * pages: first on metadata IO errors (which only
+ * report through AS_EIO) or when the page is dropped
+ * at the wrong time.
+ *
+ * So right now we assume that the application DTRT on
+ * the first EIO, but we're not worse than other parts

+
+SYNOPSIS
+--------
+[verse]
+'perf sched' {record|latency|replay|trace}
+
+DESCRIPTION
+-----------
+There's four variants of perf sched:
+
+ 'perf sched record <command>' to record the scheduling events
+ of an arbitrary workload.
+
+ 'perf sched latency' to report the per task scheduling latencies
+ and other scheduling properties of the workload.
+
+ 'perf sched trace' to see a detailed trace of the workload that
+ was recorded.
+
+ 'perf sched replay' to simulate the workload that was recorded
+ via perf sched record. (this is done by starting up mockup threads
+ that mimic the workload based on the events in the trace. These
+ threads can then replay the timings (CPU runtime and sleep patterns)
+ of the workload as it occured when it was recorded - and can repeat
+ it a number of times, measuring its performance.)
