-<para>This system call opens a named audio device (e.g. /dev/dvb/adapter0/audio0)
- for subsequent use. When an open() call has succeeded, the device will be ready
- for use. The significance of blocking or non-blocking mode is described in the
- documentation for functions where there is a difference. It does not affect the
- semantics of the open() call itself. A device opened in blocking mode can later
- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux
- manual page for fcntl. Only one user can open the Audio Device in O_RDWR
- mode. All other attempts to open the device in this mode will fail, and an error
- code will be returned. If the Audio Device is opened in O_RDONLY mode, the
- only ioctl call that can be used is AUDIO_GET_STATUS. All other call will
- return with an error code.</para>

-<title>DVB Frontend properties</title>
-<para>Tuning into a Digital TV physical channel and starting decoding it
-    requires changing a set of parameters, in order to control the
-    tuner, the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
-    antenna subsystem via Satellite Equipment Control (SEC), on satellite
-    systems. The actual parameters are specific to each particular digital
-    TV standards, and may change as the digital TV specs evolves.</para>
-<para>In the past, the strategy used was to have a union with the parameters
-    needed to tune for DVB-S, DVB-C, DVB-T and ATSC delivery systems grouped
-    there. The problem is that, as the second generation standards appeared,
-    those structs were not big enough to contain the additional parameters.
-    Also, the union didn't have any space left to be expanded without breaking
-    userspace. So, the decision was to deprecate the legacy union/struct based
-    approach, in favor of a properties set approach.</para>
-
-<para>NOTE: on Linux DVB API version 3, setting a frontend were done via
-    <link linkend="dvb-frontend-parameters">struct  <constant>dvb_frontend_parameters</constant></link>.
-    This got replaced on version 5 (also called "S2API", as this API were
-    added originally_enabled to provide support for DVB-S2), because the old
-    API has a very limited support to new standards and new hardware. This
-    section describes the new and recommended way to set the frontend, with
-    suppports all digital TV delivery systems.</para>
-
-<para>Example: with the properties based approach, in order to set the tuner
-    to a DVB-C channel at 651 kHz, modulated with 256-QAM, FEC 3/4 and symbol
-    rate of 5.217 Mbauds, those properties should be sent to

-
-		<para>Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The

-			segments from position 1-8 to 5-13 or anything in between.</para>
-
-		<para>The underlying layer of segments are subchannels: each segment is

-			is used to help the demodulator to synchronize on the channel.</para>
-
-		<para>An ISDB-T channel is always centered over all sub-channels. As for

-			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>ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial
-			Television Broadcasting".</para>
-		<para>In order to understand the ISDB specific parameters,
-			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 have up to 3 layer sharing those segments,
-			and things like that.</para>

-<para>The program assumes that you are using a universal LNB and a standard DiSEqC
-switch with up to 4 addresses. Of course, you could build in some more checking if
-tuning was successful and maybe try to repeat the tuning process. Depending on the
-external hardware, i.e. LNB and DiSEqC switch, and weather conditions this may be

-<para>The kind of parameters passed to the frontend device for tuning depend on
-the kind of hardware you are using.</para>
-<para>The struct <constant>dvb_frontend_parameters</constant> uses an
-union with specific per-system parameters. However, as newer delivery systems
-required more data, the structure size weren't enough to fit, and just
-extending its size would break the existing applications. So, those parameters
-were replaced by the usage of <link linkend="FE_GET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> ioctl's. The
-new API is flexible enough to add new parameters to existing delivery systems,
-and to add newer delivery systems.</para>
-<para>So, newer applications should use <link linkend="FE_GET_PROPERTY">
-<constant>FE_GET_PROPERTY/FE_SET_PROPERTY</constant></link> instead, in
-order to be able to support the newer System Delivery like  DVB-S2, DVB-T2,
-DVB-C2, ISDB, etc.</para>

-	} u;
-};
-</programlisting></para>
-<para>In the case of QPSK frontends the <constant>frequency</constant> field specifies the intermediate
-frequency, i.e. the offset which is effectively added to the local oscillator frequency (LOF) of
-the LNB. The intermediate frequency has to be specified in units of kHz. For QAM and
-OFDM frontends the <constant>frequency</constant> specifies the absolute frequency and is given in Hz.

-<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="https://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>

-
-<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>

-
-<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>

-<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>

- The significance of blocking or non-blocking mode is described in the

- be put into non-blocking mode (and vice versa) using the F_SETFL command
- of the fcntl system call. This is a standard system call, documented in the Linux

-
-  <section id="cec-intro">
-    <title>Introduction</title>

-    </para>
-    <para>HDMI connectors provide a single pin for use by the Consumer Electronics
-    Control protocol. This protocol allows different devices connected by an HDMI cable
-    to communicate. The protocol for CEC version 1.4 is defined in supplements 1 (CEC)
-    and 2 (HEAC or HDMI Ethernet and Audio Return Channel) of the HDMI 1.4a
-    (<xref linkend="hdmi" />) specification and the extensions added to CEC version 2.0
-    are defined in chapter 11 of the HDMI 2.0 (<xref linkend="hdmi2" />) specification.
-    </para>
-
-    <para>The bitrate is very slow (effectively no more than 36 bytes per second) and
-    is based on the ancient AV.link protocol used in old SCART connectors. The protocol
-    closely resembles a crazy Rube Goldberg contraption and is an unholy mix of low and
-    high level messages. Some messages, especially those part of the HEAC protocol layered
-    on top of CEC, need to be handled by the kernel, others can be handled either by the
-    kernel or by userspace.</para>
-
-    <para>In addition, CEC can be implemented in HDMI receivers, transmitters and in USB
-    devices that have an HDMI input and an HDMI output and that control just the CEC pin.</para>
-
-    <para>Drivers that support CEC will create a CEC device node (/dev/cecX)
-    to give userspace access to the CEC adapter. The &CEC-ADAP-G-CAPS; ioctl will tell userspace
-    what it is allowed to do.</para>

-
-    <para>By default any filehandle can use &CEC-TRANSMIT; and &CEC-RECEIVE;, but
-in order to prevent applications from stepping on each others toes it must be possible
-to obtain exclusive access to the CEC adapter. This ioctl sets the filehandle
-to initiator and/or follower mode which can be exclusive depending on the chosen
-mode. The initiator is the filehandle that is used
-to initiate messages, i.e. it commands other CEC devices. The follower is the filehandle
-that receives messages sent to the CEC adapter and processes them. The same filehandle
-can be both initiator and follower, or this role can be taken by two different
-filehandles.</para>
-
-    <para>When a CEC message is received, then the CEC framework will decide how
-it will be processed. If the message is a reply to an earlier transmitted message,
-then the reply is sent back to the filehandle that is waiting for it. In addition
-the CEC framework will process it.</para>
-
-    <para>If the message is not a reply, then the CEC framework will process it
-first. If there is no follower, then the message is just discarded and a feature
-abort is sent back to the initiator if the framework couldn't process it. If there
-is a follower, then the message is passed on to the follower who will use
-&CEC-RECEIVE; to dequeue the new message. The framework expects the follower to
-make the right decisions.</para>
-
-    <para>The CEC framework will process core messages unless requested otherwise
-by the follower. The follower can enable the passthrough mode. In that case, the
-CEC framework will pass on most core messages without processing them and
-the follower will have to implement those messages. There are some messages
-that the core will always process, regardless of the passthrough mode. See
-<xref linkend="cec-core-processing" /> for details.</para>
-
-    <para>If there is no initiator, then any CEC filehandle can use &CEC-TRANSMIT;.
-If there is an exclusive initiator then only that initiator can call &CEC-TRANSMIT;.

-      <para>The V4L2 API creates different nodes for each of these functions.</para>
-
-      <para>The V4L2 API was designed with the idea that one device node could support
-all functions. However, in practice this never worked: this 'feature'
-was never used by applications and many drivers did not support it and if
-they did it was certainly never tested. In addition, switching a device
-node between different functions only works when using the streaming I/O
-API, not with the read()/write() API.</para>
-
-      <para>Today each device node supports just one function.</para>
-
-      <para>Besides video input or output the hardware may also
-support audio sampling or playback. If so, these functions are
-implemented as ALSA PCM devices with optional ALSA audio mixer
-devices.</para>
-
-      <para>One problem with all these devices is that the V4L2 API
-makes no provisions to find these related devices. Some really
-complex devices use the Media Controller (see <xref linkend="media_controller" />)
-which can be used for this purpose. But most drivers do not use it,
-and while some code exists that uses sysfs to discover related devices
-(see libmedia_dev in the <ulink url="http://git.linuxtv.org/cgit.cgi/v4l-utils.git/">v4l-utils</ulink>
-git repository), there is no library yet that can provide a single API towards
-both Media Controller-based devices and devices that do not use the Media Controller.

-      <para>V4L2 devices can be opened more than once.<footnote><para>
-There are still some old and obscure drivers that have not been updated to
-allow for multiple opens. This implies that for such drivers &func-open; can

-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 ALSA audio mixer application.
-Just opening a V4L2 device should not change the state of the device.<footnote>
-<para>Unfortunately, opening a radio device often switches the state of the
-device to radio mode in many drivers. This behavior should be fixed eventually
-as it violates the V4L2 specification.</para></footnote></para>

-application (filehandle) becomes the owner of the device. It is no longer

-	The video standards discussed so far have been dealing with Analog TV and the
-corresponding video timings. Today there are many more different hardware interfaces
-such as High Definition TV interfaces (HDMI), VGA, DVI connectors etc., that carry
-video signals and there is a need to extend the API to select the video timings
-for these interfaces. Since it is not possible to extend the &v4l2-std-id; due to
-the limited bits available, a new set of ioctls was added to set/get video timings at
-the input and output.</para>
-
-	<para>These ioctls deal with the detailed digital video timings that define
-each video format. This includes parameters such as the active video width and height,
-signal polarities, frontporches, backporches, sync widths etc. The <filename>linux/v4l2-dv-timings.h</filename>
-header can be used to get the timings of the formats in the <xref linkend="cea861" /> and
-<xref linkend="vesadmt" /> standards.
-	</para>
-
-	<para>To enumerate and query the attributes of the DV timings supported by a device
-	applications use the &VIDIOC-ENUM-DV-TIMINGS; and &VIDIOC-DV-TIMINGS-CAP; ioctls.
-	To set DV timings for the device applications use the
-&VIDIOC-S-DV-TIMINGS; ioctl and to get current DV timings they use the
-&VIDIOC-G-DV-TIMINGS; ioctl. To detect the DV timings as seen by the video receiver applications
-use the &VIDIOC-QUERY-DV-TIMINGS; ioctl.</para>
-	<para>Applications can make use of the <xref linkend="input-capabilities" /> and
-<xref linkend="output-capabilities"/> flags to determine whether the digital video ioctls
-can be used with the given input or output.</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

-	  <para>Enumerating formats an application has no a-priori

-using the same coordinate system as &v4l2-cropcap;. Applications can
-use the <constant>VIDIOC_G_CROP</constant> and

-      <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>

-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,

-numbers beginning at zero. Rationale: a) The previous definition was

-numbers. c) There is no point in inventing a new line numbering
-scheme. We now use line number as defined by ITU-R, period.

-Drivers may allocate resources at scan line granularity and some data
-services are transmitted only on the first field. The comment that

-<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

-
-	  <para>There are new fields to identify the driver, a new RDS

-&VIDIOC-QUERYSTD; was added to autodetect the received standard, if

-
-	  <para>Struct <structname>v4l2_enumstd</structname> ceased to

-        <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>

-<footnote><para>The use of <constant>V4L2_CID_PRIVATE_BASE</constant>
-is problematic because different drivers may use the same
-<constant>V4L2_CID_PRIVATE_BASE</constant> ID for different controls.
-This makes it hard to programatically set such controls since the meaning
-of the control with that ID is driver dependent. In order to resolve this
-drivers use unique IDs and the <constant>V4L2_CID_PRIVATE_BASE</constant>
-IDs are mapped to those unique IDs by the kernel. Consider these
-<constant>V4L2_CID_PRIVATE_BASE</constant> IDs as aliases to the real
-IDs.</para>
-<para>Many applications today still use the <constant>V4L2_CID_PRIVATE_BASE</constant>
-IDs instead of using &VIDIOC-QUERYCTRL; with the <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant>
-flag to enumerate all IDs, so support for <constant>V4L2_CID_PRIVATE_BASE</constant>
-is still around.</para></footnote>
-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.</para>
-
-    <para>If a control is not applicable to the current configuration
-of the device (for example, it doesn't apply to the current video input)
-drivers set the <constant>V4L2_CTRL_FLAG_INACTIVE</constant> flag.</para>
-
-    <para>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.</para>
-
-    <para>V4L2 specifies an event mechanism to notify applications
-when controls change value (see &VIDIOC-SUBSCRIBE-EVENT;, event
-<constant>V4L2_EVENT_CTRL</constant>), panel applications might want to make
-use of that in order to always reflect the correct control value.</para>
-
-    <para>
-      All controls use machine endianness.

-
-      <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>Since the &v4l2-ext-control; supports pointers it is now
-also possible to have controls with compound types such as N-dimensional arrays
-and/or structures. You need to specify the <constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant>
-when enumerating controls to actually be able to see such compound controls.
-In other words, these controls with compound types should only be used
-programmatically.</para>
-
-      <para>Since such compound controls need to expose more information
-about themselves than is possible with &VIDIOC-QUERYCTRL; the
-&VIDIOC-QUERY-EXT-CTRL; ioctl was added. In particular, this ioctl gives
-the dimensions of the N-dimensional array if this control consists of more than
-one element.</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; (or &VIDIOC-QUERY-EXT-CTRL;) 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>
-
-      <para>
-	All controls use machine endianness.
-      </para>

-    <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
-<xref linkend="enum_all_controls" />). But if it is supported, then it is guaranteed to enumerate over
-all controls, including driver-private controls.</para>

-      <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
-for more details.</para>

-If this setting is enabled, then the rate control logic of the encoder will calculate the average bitrate
-for a GOP and keep it below or equal the set bitrate target. Otherwise the rate control logic calculates the
-overall average bitrate for the stream and keeps it below or equal to the set bitrate. In the first case
-the average bitrate for the whole stream will be smaller then the set bitrate. This is caused because the

-	    Unsynchronised LED flash is controlled directly by the

-	    before the exposure of the image starts and disabled once
-	    it ends. The host is fully responsible for the timing of
-	    the flash.

-In this context, RF tuner is radio receiver circuit between antenna and

-Tuners that could do baseband output are often called Zero-IF tuners. Older
-tuners were typically simple PLL tuners inside a metal box, whilst newer ones
-are highly integrated chips without a metal box "silicon tuners". These controls

-tuners does not have much adjustable features.

-into the (VGA-)video signal of a graphics card, or to store captured
-images directly in video memory of a graphics card, typically with

-
-    <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>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

-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

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

-an &EINVAL; only when the given parameters are ambiguous, otherwise
-they modify the parameters according to the hardware capabilities and
-return the actual parameters. When the driver allocates resources at

-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,

-  <title>Sub-device Interface</title>
-
-  <para>The complex nature of V4L2 devices, where hardware is often made of
-  several integrated circuits that need to interact with each other in a
-  controlled way, leads to complex V4L2 drivers. The drivers usually reflect
-  the hardware model in software, and model the different hardware components
-  as software blocks called sub-devices.</para>
-
-  <para>V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
-  implements the media device API, they will automatically inherit from media
-  entities. Applications will be able to enumerate the sub-devices and discover
-  the hardware topology using the media entities, pads and links enumeration
-  API.</para>
-
-  <para>In addition to make sub-devices discoverable, drivers can also choose
-  to make them directly configurable by applications. When both the sub-device
-  driver and the V4L2 device driver support this, sub-devices will feature a
-  character device node on which ioctls can be called to

-    <title>Controls</title>
-    <para>Most V4L2 controls are implemented by sub-device hardware. Drivers
-    usually merge all controls and expose them through video device nodes.
-    Applications can control all sub-devices through a single interface.</para>
-
-    <para>Complex devices sometimes implement the same control in different
-    pieces of hardware. This situation is common in embedded platforms, where
-    both sensors and image processing hardware implement identical functions,
-    such as contrast adjustment, white balance or faulty pixels correction. As
-    the V4L2 controls API doesn't support several identical controls in a single
-    device, all but one of the identical controls are hidden.</para>
-
-    <para>Applications can access those hidden controls through the sub-device
-    node with the V4L2 control API described in <xref linkend="control" />. The
-    ioctls behave identically as when issued on V4L2 device nodes, with the
-    exception that they deal only with controls implemented in the sub-device.
-    </para>
-
-    <para>Depending on the driver, those controls might also be exposed through
-    one (or several) V4L2 device nodes.</para>

-  <section>
-    <title>Events</title>
-    <para>V4L2 sub-devices can notify applications of events as described in
-    <xref linkend="event" />. The API behaves identically as when used on V4L2
-    device nodes, with the exception that it only deals with events generated by
-    the sub-device. Depending on the driver, those events might also be reported
-    on one (or several) V4L2 device nodes.</para>

-
-    <para>Image formats are typically negotiated on video capture and
-    output devices using the format and <link
-    linkend="vidioc-subdev-g-selection">selection</link> ioctls. The
-    driver is responsible for configuring every block in the video
-    pipeline according to the requested format at the pipeline input
-    and/or output.</para>
-
-    <para>For complex devices, such as often found in embedded systems,
-    identical image sizes at the output of a pipeline can be achieved using
-    different hardware configurations. One such example is shown on
-    <xref linkend="pipeline-scaling" />, where
-    image scaling can be performed on both the video sensor and the host image
-    processing hardware.</para>

-
-    <para>The sensor scaler is usually of less quality than the host scaler, but
-    scaling on the sensor is required to achieve higher frame rates. Depending
-    on the use case (quality vs. speed), the pipeline must be configured
-    differently. Applications need to configure the formats at every point in
-    the pipeline explicitly.</para>
-
-    <para>Drivers that implement the <link linkend="media-controller-intro">media
-    API</link> can expose pad-level image format configuration to applications.
-    When they do, applications can use the &VIDIOC-SUBDEV-G-FMT; and
-    &VIDIOC-SUBDEV-S-FMT; ioctls. to negotiate formats on a per-pad basis.</para>
-
-    <para>Applications are responsible for configuring coherent parameters on
-    the whole pipeline and making sure that connected pads have compatible
-    formats. The pipeline is checked for formats mismatch at &VIDIOC-STREAMON;
-    time, and an &EPIPE; is then returned if the configuration is
-    invalid.</para>
-
-    <para>Pad-level image format configuration support can be tested by calling
-    the &VIDIOC-SUBDEV-G-FMT; ioctl on pad 0. If the driver returns an &EINVAL;
-    pad-level format configuration is not supported by the sub-device.</para>
-
-    <section>
-      <title>Format Negotiation</title>
-
-      <para>Acceptable formats on pads can (and usually do) depend on a number
-      of external parameters, such as formats on other pads, active links, or
-      even controls. Finding a combination of formats on all pads in a video
-      pipeline, acceptable to both application and driver, can't rely on formats
-      enumeration only. A format negotiation mechanism is required.</para>
-
-      <para>Central to the format negotiation mechanism are the get/set format
-      operations. When called with the <structfield>which</structfield> argument
-      set to <constant>V4L2_SUBDEV_FORMAT_TRY</constant>, the
-      &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of
-      formats parameters that are not connected to the hardware configuration.
-      Modifying those 'try' formats leaves the device state untouched (this
-      applies to both the software state stored in the driver and the hardware
-      state stored in the device itself).</para>
-
-      <para>While not kept as part of the device state, try formats are stored
-      in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return
-      the last try format set <emphasis>on the same sub-device file
-      handle</emphasis>. Several applications querying the same sub-device at
-      the same time will thus not interact with each other.</para>
-
-      <para>To find out whether a particular format is supported by the device,
-      applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if
-      needed, change the requested <structfield>format</structfield> based on
-      device requirements and return the possibly modified value. Applications
-      can then choose to try a different format or accept the returned value and
-      continue.</para>
-
-      <para>Formats returned by the driver during a negotiation iteration are
-      guaranteed to be supported by the device. In particular, drivers guarantee
-      that a returned format will not be further changed if passed to an
-      &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as
-      formats on other pads or links' configuration are not changed).</para>
-
-      <para>Drivers automatically propagate formats inside sub-devices. When a
-      try or active format is set on a pad, corresponding formats on other pads
-      of the same sub-device can be modified by the driver. Drivers are free to
-      modify formats as required by the device. However, they should comply with
-      the following rules when possible:
-      <itemizedlist>
-        <listitem><para>Formats should be propagated from sink pads to source pads.
-	Modifying a format on a source pad should not modify the format on any
-	sink pad.</para></listitem>
-        <listitem><para>Sub-devices that scale frames using variable scaling factors
-	should reset the scale factors to default values when sink pads formats
-	are modified. If the 1:1 scaling ratio is supported, this means that
-	source pads formats should be reset to the sink pads formats.</para></listitem>
-      </itemizedlist>
-      </para>
-
-      <para>Formats are not propagated across links, as that would involve
-      propagating them from one sub-device file handle to another. Applications
-      must then take care to configure both ends of every link explicitly with
-      compatible formats. Identical formats on the two ends of a link are
-      guaranteed to be compatible. Drivers are free to accept different formats
-      matching device requirements as being compatible.</para>

-      <title>Selections: cropping, scaling and composition</title>
-
-      <para>Many sub-devices support cropping frames on their input or output
-      pads (or possible even on both). Cropping is used to select the area of
-      interest in an image, typically on an image sensor or a video decoder. It can
-      also be used as part of digital zoom implementations to select the area of
-      the image that will be scaled up.</para>
-
-      <para>Crop settings are defined by a crop rectangle and represented in a
-      &v4l2-rect; by the coordinates of the top left corner and the rectangle
-      size. Both the coordinates and sizes are expressed in pixels.</para>
-
-      <para>As for pad formats, drivers store try and active
-      rectangles for the selection targets <xref
-      linkend="v4l2-selections-common" />.</para>
-
-      <para>On sink pads, cropping is applied relative to the
-      current pad format. The pad format represents the image size as
-      received by the sub-device from the previous block in the
-      pipeline, and the crop rectangle represents the sub-image that
-      will be transmitted further inside the sub-device for
-      processing.</para>
-
-      <para>The scaling operation changes the size of the image by
-      scaling it to new dimensions. The scaling ratio isn't specified
-      explicitly, but is implied from the original and scaled image
-      sizes. Both sizes are represented by &v4l2-rect;.</para>
-
-      <para>Scaling support is optional. When supported by a subdev,
-      the crop rectangle on the subdev's sink pad is scaled to the
-      size configured using the &VIDIOC-SUBDEV-S-SELECTION; IOCTL
-      using <constant>V4L2_SEL_TGT_COMPOSE</constant>
-      selection target on the same pad. If the subdev supports scaling
-      but not composing, the top and left values are not used and must
-      always be set to zero.</para>
-
-      <para>On source pads, cropping is similar to sink pads, with the
-      exception that the source size from which the cropping is
-      performed, is the COMPOSE rectangle on the sink pad. In both
-      sink and source pads, the crop rectangle must be entirely
-      contained inside the source image size for the crop
-      operation.</para>

-Teletext packages and storing formatted pages in cache memory. Such

-ftp://ftp.gwdg.de/pub/linux/misc/videotext/</ulink>. (Videotext is the name of

-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

-signal. On error, -1 is returned, and the <varname>errno</varname>

-  <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>

-</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>

-  <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 with the memory type set to <constant>V4L2_MEMORY_MMAP</constant>.</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. In the single-planar API case, the
-<structfield>m.offset</structfield> and <structfield>length</structfield>

-    <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 (aka odd) and
-bottom (aka even) 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
-calling the &VIDIOC-S-FMT; ioctl. If this is not desired it should
-have the value <constant>V4L2_FIELD_ANY</constant> (0).</para>

-</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>
-		<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>

-		<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>

-<title>Introduction</title>
-
-<para>The LIRC device interface is a bi-directional interface for
-transporting raw IR data between userspace and kernelspace. Fundamentally,
-it is just a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number
-of standard struct file_operations defined on it. With respect to
-transporting raw IR data to and fro, the essential fops are read, write
-and ioctl.</para>

-<section id="lirc_read">
-<title>LIRC read fop</title>
-
-<para>The lircd userspace daemon reads raw IR data from the LIRC chardev. The
-exact format of the data depends on what modes a driver supports, and what
-mode has been selected. lircd obtains supported modes and sets the active mode
-via the ioctl interface, detailed at <xref linkend="lirc_ioctl"/>. The generally
-preferred mode is LIRC_MODE_MODE2, in which packets containing an int value
-describing an IR signal are read from the chardev.</para>

-
-<section id="lirc_write">
-<title>LIRC write fop</title>
-
-<para>The data written to the chardev is a pulse/space sequence of integer
-values. Pulses and spaces are only marked implicitly by their position. The
-data must start and end with a pulse, therefore, the data must always include
-an uneven number of samples. The write function must block until the data has
-been transmitted by the hardware. If more data is provided than the hardware
-can send, the driver returns EINVAL.</para>
-
-</section>

-<section id="lirc_ioctl">
-<title>LIRC ioctl fop</title>
-
-<para>The LIRC device's ioctl definition is bound by the ioctl function
-definition of struct file_operations, leaving us with an unsigned int
-for the ioctl command and an unsigned long for the arg. For the purposes
-of ioctl portability across 32-bit and 64-bit, these values are capped
-to their 32-bit sizes.</para>
-
-<para>The following ioctls can be used to change specific hardware settings.
-In general each driver should have a default set of settings. The driver
-implementation is expected to re-apply the default settings when the device
-is closed by user-space, so that every application opening the device can rely
-on working with the default settings initially.</para>

-      that prevents them to be used with some remotes.
-      Wide band receiver might also be more precise
-      On the other hand its disadvantage it usually reduced range of reception.
-      Note: wide band receiver might be implictly enabled if you enable

-    <title>Introduction</title>
-    <para>Media devices increasingly handle multiple related functions. Many USB
-    cameras include microphones, video capture hardware can also output video,
-    or SoC camera interfaces also perform memory-to-memory operations similar to
-    video codecs.</para>
-    <para>Independent functions, even when implemented in the same hardware, can
-    be modelled as separate devices. A USB camera with a microphone will be
-    presented to userspace applications as V4L2 and ALSA capture devices. The
-    devices' relationships (when using a webcam, end-users shouldn't have to
-    manually select the associated USB microphone), while not made available
-    directly to applications by the drivers, can usually be retrieved from
-    sysfs.</para>
-    <para>With more and more advanced SoC devices being introduced, the current
-    approach will not scale. Device topologies are getting increasingly complex
-    and can't always be represented by a tree structure. Hardware blocks are
-    shared between different functions, creating dependencies between seemingly
-    unrelated devices.</para>
-    <para>Kernel abstraction APIs such as V4L2 and ALSA provide means for
-    applications to access hardware parameters. As newer hardware expose an
-    increasingly high number of those parameters, drivers need to guess what
-    applications really require based on limited information, thereby
-    implementing policies that belong to userspace.</para>
-    <para>The media controller API aims at solving those problems.</para>

-    <title>Media device model</title>
-    <para>Discovering a device internal topology, and configuring it at runtime,
-    is one of the goals of the media controller API. To achieve this, hardware
-    devices and Linux Kernel interfaces are modelled as graph objects on
-    an oriented graph. The object types that constitute the graph are:</para>
-    <itemizedlist>
-    <listitem><para>An <emphasis role="bold">entity</emphasis>
-    is a basic media hardware or software building block. It can correspond to
-    a large variety of logical blocks such as physical hardware devices
-    (CMOS sensor for instance), logical hardware devices (a building block in
-    a System-on-Chip image processing pipeline), DMA channels or physical
-    connectors.</para></listitem>
-    <listitem><para>An <emphasis role="bold">interface</emphasis>
-    is a graph representation of a Linux Kernel userspace API interface,
-    like a device node or a sysfs file that controls one or more entities
-    in the graph.</para></listitem>
-    <listitem><para>A <emphasis role="bold">pad</emphasis>
-    is a data connection endpoint through which an entity can interact with
-    other entities. Data (not restricted to video) produced by an entity
-    flows from the entity's output to one or more entity inputs. Pads should
-    not be confused with physical pins at chip boundaries.</para></listitem>
-    <listitem><para>A <emphasis role="bold">data link</emphasis>
-    is a point-to-point oriented connection between two pads, either on the
-    same entity or on different entities. Data flows from a source pad to a
-    sink pad.</para></listitem>
-    <listitem><para>An <emphasis role="bold">interface link</emphasis>

-    Kernel interface and an entity.m</para></listitem>

-	<para>These are two-plane versions of the YUV 4:4:4 format. The three
-	components are separated into two sub-images or planes. The Y plane is
-	first, with each Y sample stored in one byte per pixel. For
-	<constant>V4L2_PIX_FMT_NV24</constant>, a combined CbCr plane
-	immediately follows the Y plane in memory. The CbCr plane has the same
-	width and height, in pixels, as the Y plane (and the image). Each line
-	contains one CbCr pair per pixel, with each Cb and Cr sample stored in
-	one byte. <constant>V4L2_PIX_FMT_NV42</constant> is the same except that
-	the Cb and Cr samples are swapped, the CrCb plane starts with a Cr
-	sample.</para>
-
-	<para>If the Y plane has pad bytes after each row, then the CbCr plane
-	has twice as many pad bytes after its rows.</para>

-follows the Y plane in memory. The Cr plane is &frac14; the width and
-&frac14; the height of the Y plane (and of the image). Each Cr belongs
-to 16 pixels, a four-by-four square of the image. Following the Cr
-plane is the Cb plane, just like the Cr plane.
-<constant>V4L2_PIX_FMT_YUV410</constant> is the same, except the Cb
-plane comes first, then the Cr plane.</para>

-	<para>This format is not commonly used. This is a planar
-format similar to the 4:2:2 planar format except with half as many
-chroma. The three components are separated into three sub-images or
-planes. The Y plane is first. The Y plane has one byte per pixel. The
-Cb plane immediately follows the Y plane in memory. The Cb plane is
-&frac14; the width of the Y plane (and of the image). Each Cb belongs
-to 4 pixels all on the same row. For example,
-Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
-Y'<subscript>01</subscript>, Y'<subscript>02</subscript> and
-Y'<subscript>03</subscript>. Following the Cb plane is the Cr plane,
-just like the Cb plane.</para>

-	<para>If the Y plane has pad bytes after each row, then the Cr
-and Cb planes have &frac14; as many pad bytes after their rows. In
-other words, four C x rows (including padding) is exactly as long as

-    <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">videodev2.h</link> header file. These identifiers
-represent <link linkend="v4l2-fourcc">four character (FourCC) codes</link>
-which are also listed below, however they are not the same as those
-used in the Windows world.</para>
-
-    <para>For some formats, data is stored in separate, discontiguous
-memory buffers. Those formats are identified by a separate set of FourCC codes
-and are referred to as "multi-planar formats". For example, a YUV422 frame is
-normally stored in one memory buffer, but it can also be placed in two or three
-separate buffers, with Y component in one buffer and CbCr components in another
-in the 2-planar version or with each component in its own buffer in the
-3-planar case. Those sub-buffers are referred to as "planes".</para>

-  <section id="colorspaces">
-    <title>Colorspaces</title>
-
-    <para>'Color' is a very complex concept and depends on physics, chemistry and
-biology. Just because you have three numbers that describe the 'red', 'green'
-and 'blue' components of the color of a pixel does not mean that you can accurately
-display that color. A colorspace defines what it actually <emphasis>means</emphasis>
-to have an RGB value of e.g. (255,&nbsp;0,&nbsp;0). That is, which color should be
-reproduced on the screen in a perfectly calibrated environment.</para>
-
-    <para>In order to do that we first need to have a good definition of
-color, i.e. some way to uniquely and unambiguously define a color so that someone
-else can reproduce it. Human color vision is trichromatic since the human eye has
-color receptors that are sensitive to three different wavelengths of light. Hence
-the need to use three numbers to describe color. Be glad you are not a mantis shrimp
-as those are sensitive to 12 different wavelengths, so instead of RGB we would be
-using the ABCDEFGHIJKL colorspace...</para>
-
-    <para>Color exists only in the eye and brain and is the result of how strongly
-color receptors are stimulated. This is based on the Spectral
-Power Distribution (SPD) which is a graph showing the intensity (radiant power)
-of the light at wavelengths covering the visible spectrum as it enters the eye.
-The science of colorimetry is about the relationship between the SPD and color as
-perceived by the human brain.</para>
-
-    <para>Since the human eye has only three color receptors it is perfectly
-possible that different SPDs will result in the same stimulation of those receptors
-and are perceived as the same color, even though the SPD of the light is
-different.</para>
-
-   <para>In the 1920s experiments were devised to determine the relationship
-between SPDs and the perceived color and that resulted in the CIE 1931 standard
-that defines spectral weighting functions that model the perception of color.
-Specifically that standard defines functions that can take an SPD and calculate
-the stimulus for each color receptor. After some further mathematical transforms
-these stimuli are known as the <emphasis>CIE XYZ tristimulus</emphasis> values
-and these X, Y and Z values describe a color as perceived by a human unambiguously.
-These X, Y and Z values are all in the range [0&hellip;1].</para>
-
-   <para>The Y value in the CIE XYZ colorspace corresponds to luminance. Often
-the CIE XYZ colorspace is transformed to the normalized CIE xyY colorspace:</para>
-
-   <para>x = X / (X + Y + Z)</para>
-   <para>y = Y / (X + Y + Z)</para>
-
-   <para>The x and y values are the chromaticity coordinates and can be used to
-define a color without the luminance component Y. It is very confusing to
-have such similar names for these colorspaces. Just be aware that if colors
-are specified with lower case 'x' and 'y', then the CIE xyY colorspace is
-used. Upper case 'X' and 'Y' refer to the CIE XYZ colorspace. Also, y has nothing
-to do with luminance. Together x and y specify a color, and Y the luminance.
-That is really all you need to remember from a practical point of view. At
-the end of this section you will find reading resources that go into much more
-detail if you are interested.
-</para>
-
-   <para>A monitor or TV will reproduce colors by emitting light at three
-different wavelengths, the combination of which will stimulate the color receptors
-in the eye and thus cause the perception of color. Historically these wavelengths
-were defined by the red, green and blue phosphors used in the displays. These
-<emphasis>color primaries</emphasis> are part of what defines a colorspace.</para>
-
-    <para>Different display devices will have different primaries and some
-primaries are more suitable for some display technologies than others. This has
-resulted in a variety of colorspaces that are used for different display
-technologies or uses. To define a colorspace you need to define the three
-color primaries (these are typically defined as x,&nbsp;y chromaticity coordinates
-from the CIE xyY colorspace) but also the white reference: that is the color obtained
-when all three primaries are at maximum power. This determines the relative power
-or energy of the primaries. This is usually chosen to be close to daylight which has
-been defined as the CIE D65 Illuminant.</para>
-
-    <para>To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
-Other colorspaces are defined by three chromaticity coordinates defined in the
-CIE xyY colorspace. Based on those a 3x3 matrix can be constructed that
-transforms CIE XYZ colors to colors in the new colorspace.
-</para>
-
-    <para>Both the CIE XYZ and the RGB colorspace that are derived from the
-specific chromaticity primaries are linear colorspaces. But neither the eye,
-nor display technology is linear. Doubling the values of all components in
-the linear colorspace will not be perceived as twice the intensity of the color.
-So each colorspace also defines a transfer function that takes a linear color
-component value and transforms it to the non-linear component value, which is a
-closer match to the non-linear performance of both the eye and displays. Linear
-component values are denoted RGB, non-linear are denoted as R'G'B'. In general
-colors used in graphics are all R'G'B', except in openGL which uses linear RGB.
-Special care should be taken when dealing with openGL to provide linear RGB colors
-or to use the built-in openGL support to apply the inverse transfer function.</para>
-
-    <para>The final piece that defines a colorspace is a function that
-transforms non-linear R'G'B' to non-linear Y'CbCr. This function is determined
-by the so-called luma coefficients. There may be multiple possible Y'CbCr
-encodings allowed for the same colorspace. Many encodings of color
-prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the human
-eye is more sensitive to differences in luminance than in color this encoding
-allows one to reduce the amount of color information compared to the luma
-data. Note that the luma (Y') is unrelated to the Y in the CIE XYZ colorspace.
-Also note that Y'CbCr is often called YCbCr or YUV even though these are
-strictly speaking wrong.</para>
-
-    <para>Sometimes people confuse Y'CbCr as being a colorspace. This is not
-correct, it is just an encoding of an R'G'B' color into luma and chroma
-values. The underlying colorspace that is associated with the R'G'B' color
-is also associated with the Y'CbCr color.</para>
-
-    <para>The final step is how the RGB, R'G'B' or Y'CbCr values are
-quantized. The CIE XYZ colorspace where X, Y and Z are in the range
-[0&hellip;1] describes all colors that humans can perceive, but the transform to
-another colorspace will produce colors that are outside the [0&hellip;1] range.
-Once clamped to the [0&hellip;1] range those colors can no longer be reproduced
-in that colorspace. This clamping is what reduces the extent or gamut of the
-colorspace. How the range of [0&hellip;1] is translated to integer values in the
-range of [0&hellip;255] (or higher, depending on the color depth) is called the
-quantization. This is <emphasis>not</emphasis> part of the colorspace
-definition. In practice RGB or R'G'B' values are full range, i.e. they
-use the full [0&hellip;255] range. Y'CbCr values on the other hand are limited
-range with Y' using [16&hellip;235] and Cb and Cr using [16&hellip;240].</para>
-
-    <para>Unfortunately, in some cases limited range RGB is also used
-where the components use the range [16&hellip;235]. And full range Y'CbCr also exists
-using the [0&hellip;255] range.</para>
-
-    <para>In order to correctly interpret a color you need to know the
-quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr encoding
-and the colorspace.
-From that information you can calculate the corresponding CIE XYZ color
-and map that again to whatever colorspace your display device uses.</para>
-
-    <para>The colorspace definition itself consists of the three
-chromaticity primaries, the white reference chromaticity, a transfer
-function and the luma coefficients needed to transform R'G'B' to Y'CbCr. While
-some colorspace standards correctly define all four, quite often the colorspace
-standard only defines some, and you have to rely on other standards for
-the missing pieces. The fact that colorspaces are often a mix of different
-standards also led to very confusing naming conventions where the name of
-a standard was used to name a colorspace when in fact that standard was
-part of various other colorspaces as well.</para>
-
-    <para>If you want to read more about colors and colorspaces, then the
-following resources are useful: <xref linkend="poynton" /> is a good practical
-book for video engineers, <xref linkend="colimg" /> has a much broader scope and

-    <title>Defining Colorspaces in V4L2</title>
-    <para>In V4L2 colorspaces are defined by four values. The first is the colorspace
-identifier (&v4l2-colorspace;) which defines the chromaticities, the default transfer
-function, the default Y'CbCr encoding and the default quantization method. The second
-is the transfer function identifier (&v4l2-xfer-func;) to specify non-standard
-transfer functions. The third is the Y'CbCr encoding identifier (&v4l2-ycbcr-encoding;)
-to specify non-standard Y'CbCr encodings and the fourth is the quantization identifier
-(&v4l2-quantization;) to specify non-standard quantization methods. Most of the time
-only the colorspace field of &v4l2-pix-format; or &v4l2-pix-format-mplane; needs to
-be filled in. Note that the default R'G'B' quantization is full range for all
-colorspaces except for BT.2020 which uses limited range R'G'B' quantization.</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>

-	    <entry>Two-planar format used by Samsung S5C73MX cameras. The
-first plane contains interleaved JPEG and UYVY image data, followed by meta data
-in form of an array of offsets to the UYVY data blocks. The actual pointer array
-follows immediately the interleaved JPEG/UYVY data, the number of entries in
-this array equals the height of the UYVY image. Each entry is a 4-byte unsigned
-integer in big endian order and it's an offset to a single pixel line of the
-UYVY image. The first plane can start either with JPEG or UYVY data chunk. The
-size of a single UYVY block equals the UYVY image's width multiplied by 2. The
-size of a JPEG chunk depends on the image and can vary with each line.
-<para>The second plane, at an offset of 4084 bytes, contains a 4-byte offset to
-the pointer array in the first plane. This offset is followed by a 4-byte value
-indicating size of the pointer array. All numbers in the second plane are also
-in big endian order. Remaining data in the second plane is undefined. The
-information in the second plane allows to easily find location of the pointer
-array, which can be different for each frame. The size of the pointer array is
-constant for given UYVY image height.</para>
-<para>In order to extract UYVY and JPEG frames an application can initially set
-a data pointer to the start of first plane and then add an offset from the first
-entry of the pointers table. Such a pointer indicates start of an UYVY image
-pixel line. Whole UYVY line can be copied to a separate buffer. These steps
-should be repeated for each line, i.e. the number of entries in the pointer
-array. Anything what's in between the UYVY lines is JPEG data and should be
-concatenated to form the JPEG stream. </para>

-<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>A Remote Controller interface is mapped as a normal evdev/input interface, just like a keyboard or a mouse.
-So, it uses all ioctls already defined for any other input devices.</para>
-<para>However, remove controllers are more flexible than a normal input device, as the IR
-receiver (and/or transmitter) can be used in conjunction with a wide variety of different IR remotes.</para>
-<para>In order to allow flexibility, the Remote Controller subsystem allows controlling the
-RC-specific attributes via <link linkend="remote_controllers_sysfs_nodes">the sysfs class nodes</link>.</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>

-<para>Some video capture devices can sample a subsection of a picture and

-horizontal offset into a video signal. We call these abilities cropping,
-scaling and composing.</para>
-
-<para>On a video <emphasis>capture</emphasis> device the source is a video
-signal, and the cropping target determine the area actually sampled. The sink
-is an image stored in a memory buffer.  The composing area specifies which part

-
-<para>On a video <emphasis>output</emphasis> device the source is an image in a

-
-<para>Applications can use the <link linkend="vidioc-g-selection">selection
-API</link> to select an area in a video signal or a buffer, and to query for
-default settings and hardware limits.</para>
-
-<para>Video hardware can have various cropping, composing and scaling
-limitations. It may only scale up or down, support only discrete scaling
-factors, or have different scaling abilities in the horizontal and vertical
-directions. Also it may not support scaling at all. At the same time the
-cropping/composing rectangles may have to be aligned, and both the source and
-the sink may have arbitrary upper and lower size limits. Therefore, as usual,
-drivers are expected to adjust the requested parameters and return the actual
-values selected. An application can control the rounding behaviour using <link
-linkend="v4l2-selection-flags"> constraint flags </link>.</para>

-   <title>Configuration of video capture</title>
-
-<para>See figure <xref linkend="sel-targets-capture" /> for examples of the
-selection targets available for a video capture device.  It is recommended to
-configure the cropping targets before to the composing targets.</para>
-
-<para>The range of coordinates of the top left corner, width and height of
-areas that can be sampled is given by the <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>
-target. It is recommended for the driver developers to put the
-top/left corner at position <constant>(0,0)</constant>.  The rectangle's
-coordinates are expressed in pixels.</para>
-
-<para>The top left corner, width and height of the source rectangle, that is
-the area actually sampled, is given by the <constant>V4L2_SEL_TGT_CROP</constant>
-target. It uses the same coordinate system as <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>.
-The active cropping area must lie completely inside the capture boundaries. The
-driver may further adjust the requested size and/or position according to hardware
-limitations.</para>
-
-<para>Each capture device has a default source rectangle, given by the
-<constant>V4L2_SEL_TGT_CROP_DEFAULT</constant> target. This rectangle shall
-over what the driver writer considers the complete picture.  Drivers shall set
-the active crop rectangle to the default when the driver is first loaded, but
-not later.</para>
-
-<para>The composing targets refer to a memory buffer. The limits of composing
-coordinates are obtained using <constant>V4L2_SEL_TGT_COMPOSE_BOUNDS</constant>.
-All coordinates are expressed in pixels. The rectangle's top/left
-corner must be located at position <constant>(0,0)</constant>. The width and
-height are equal to the image size set by <constant>VIDIOC_S_FMT</constant>.
-</para>
-
-<para>The part of a buffer into which the image is inserted by the hardware is
-controlled by the <constant>V4L2_SEL_TGT_COMPOSE</constant> target.
-The rectangle's coordinates are also expressed in the same coordinate system as
-the bounds rectangle. The composing rectangle must lie completely inside bounds
-rectangle. The driver must adjust the composing rectangle to fit to the
-bounding limits. Moreover, the driver can perform other adjustments according
-to hardware limitations. The application can control rounding behaviour using
-<link linkend="v4l2-selection-flags"> constraint flags</link>.</para>
-
-<para>For capture devices the default composing rectangle is queried using
-<constant>V4L2_SEL_TGT_COMPOSE_DEFAULT</constant>. It is usually equal to the
-bounding rectangle.</para>
-
-<para>The part of a buffer that is modified by the hardware is given by
-<constant>V4L2_SEL_TGT_COMPOSE_PADDED</constant>. It contains all pixels
-defined using <constant>V4L2_SEL_TGT_COMPOSE</constant> plus all
-padding data modified by hardware during insertion process. All pixels outside
-this rectangle <emphasis>must not</emphasis> be changed by the hardware. The
-content of pixels that lie inside the padded area but outside active area is
-undefined. The application can use the padded and active rectangles to detect
-where the rubbish pixels are located and remove them if needed.</para>

-
-   <title>Configuration of video output</title>
-
-<para>For output devices targets and ioctls are used similarly to the video
-capture case. The <emphasis>composing</emphasis> rectangle refers to the
-insertion of an image into a video signal. The cropping rectangles refer to a
-memory buffer. It is recommended to configure the composing targets before to
-the cropping targets.</para>
-
-<para>The cropping targets refer to the memory buffer that contains an image to
-be inserted into a video signal or graphical screen. The limits of cropping
-coordinates are obtained using <constant>V4L2_SEL_TGT_CROP_BOUNDS</constant>.
-All coordinates are expressed in pixels. The top/left corner is always point
-<constant>(0,0)</constant>.  The width and height is equal to the image size
-specified using <constant>VIDIOC_S_FMT</constant> ioctl.</para>
-
-<para>The top left corner, width and height of the source rectangle, that is
-the area from which image date are processed by the hardware, is given by the
-<constant>V4L2_SEL_TGT_CROP</constant>. Its coordinates are expressed
-in in the same coordinate system as the bounds rectangle. The active cropping
-area must lie completely inside the crop boundaries and the driver may further
-adjust the requested size and/or position according to hardware
-limitations.</para>
-
-<para>For output devices the default cropping rectangle is queried using
-<constant>V4L2_SEL_TGT_CROP_DEFAULT</constant>. It is usually equal to the
-bounding rectangle.</para>
-
-<para>The part of a video signal or graphics display where the image is
-inserted by the hardware is controlled by <constant>V4L2_SEL_TGT_COMPOSE</constant>
-target.  The rectangle's coordinates are expressed in pixels. The composing
-rectangle must lie completely inside the bounds rectangle.  The driver must
-adjust the area to fit to the bounding limits.  Moreover, the driver can
-perform other adjustments according to hardware limitations.</para>
-
-<para>The device has a default composing rectangle, given by the
-<constant>V4L2_SEL_TGT_COMPOSE_DEFAULT</constant> target. This rectangle shall cover what
-the driver writer considers the complete picture. It is recommended for the
-driver developers to put the top/left corner at position <constant>(0,0)</constant>.
-Drivers shall set the active composing rectangle to the default
-one when the driver is first loaded.</para>
-
-<para>The devices may introduce additional content to video signal other than
-an image from memory buffers.  It includes borders around an image. However,
-such a padded area is driver-dependent feature not covered by this document.
-Driver developers are encouraged to keep padded rectangle equal to active one.
-The padded target is accessed by the <constant>V4L2_SEL_TGT_COMPOSE_PADDED</constant>
-identifier.  It must contain all pixels from the <constant>V4L2_SEL_TGT_COMPOSE</constant>
-target.</para>

-
-     <title>Scaling control</title>
-
-<para>An application can detect if scaling is performed by comparing the width
-and the height of rectangles obtained using <constant>V4L2_SEL_TGT_CROP</constant>
-and <constant>V4L2_SEL_TGT_COMPOSE</constant> targets. If
-these are not equal then the scaling is applied. The application can compute
-the scaling ratios using these values.</para>

-    <title>Comparison with old cropping API</title>
-
-<para>The selection API was introduced to cope with deficiencies of previous
-<link linkend="crop"> API</link>, that was designed to control simple capture
-devices. Later the cropping API was adopted by video output drivers. The ioctls
-are used to select a part of the display were the video signal is inserted. It
-should be considered as an API abuse because the described operation is
-actually the composing.  The selection API makes a clear distinction between
-composing and cropping operations by setting the appropriate targets.  The V4L2
-API lacks any support for composing to and cropping from an image inside a
-memory buffer.  The application could configure a capture device to fill only a
-part of an image by abusing V4L2 API.  Cropping a smaller image from a larger
-one is achieved by setting the field
-&v4l2-pix-format;<structfield>::bytesperline</structfield>.  Introducing an image offsets
-could be done by modifying field &v4l2-buffer;<structfield>::m_userptr</structfield>
-before calling <constant>VIDIOC_QBUF</constant>. Those
-operations should be avoided because they are not portable (endianness), and do
-not work for macroblock and Bayer formats and mmap buffers.  The selection API
-deals with configuration of buffer cropping/composing in a clear, intuitive and
-portable way.  Next, with the selection API the concepts of the padded target
-and constraints flags are introduced.  Finally, &v4l2-crop; and &v4l2-cropcap;
-have no reserved fields. Therefore there is no way to extend their functionality.
-The new &v4l2-selection; provides a lot of place for future
-extensions.  Driver developers are encouraged to implement only selection API.
-The former cropping API would be simulated using the new one.</para>

-    <title>Media Bus Pixel Codes</title>
-
-    <para>The media bus pixel codes describe image formats as flowing over
-    physical busses (both between separate physical components and inside SoC
-    devices). This should not be confused with the V4L2 pixel formats that
-    describe, using four character codes, image formats as stored in memory.
-    </para>
-
-    <para>While there is a relationship between image formats on busses and

-	<listitem><para>The red, green and blue components order code, as encoded in a
-	pixel sample. Possible values are RGB and BGR.</para></listitem>

-	the bus width must be transferred in multiple samples. Common values are
-	1 and 2.</para></listitem>
-	<listitem><para>The bus width.</para></listitem>
-	<listitem><para>For formats where the total number of bits per pixel is smaller
-	than the number of bus samples per pixel times the bus width, a padding
-	value stating if the bytes are padded in their most high order bits
-	(PADHI) or low order bits (PADLO). A "C" prefix is used for component-wise
-	padding in the most high order bits (CPADHI) or low order bits (CPADLO)
-	of each separate component.</para></listitem>

-      <para>On LVDS buses, usually each sample is transferred serialized in
-      seven time slots per pixel clock, on three (18-bit) or four (24-bit)
-      differential data pairs at the same time. The remaining bits are used for
-      control signals as defined by SPWG/PSWG/VESA or JEIDA standards.

-      The format code is made of the following information.
-      <itemizedlist>
-	<listitem><para>The red, green and blue components order code, as encoded in a
-	pixel sample. The possible values are shown in <xref

-	transferred on the same number of bits. Common values are 8, 10 and 12.</para>
-	</listitem>
-	<listitem><para>The compression (optional). If the pixel components are
-	ALAW- or DPCM-compressed, a mention of the compression scheme and the
-	number of bits per compressed pixel component.</para></listitem>
-	<listitem><para>The number of bus samples per pixel. Pixels that are wider than
-	the bus width must be transferred in multiple samples. Common values are
-	1 and 2.</para></listitem>
-	<listitem><para>The bus width.</para></listitem>
-	<listitem><para>For formats where the total number of bits per pixel is smaller
-	than the number of bus samples per pixel times the bus width, a padding
-	value stating if the bytes are padded in their most high order bits
-	(PADHI) or low order bits (PADLO).</para></listitem>
-	<listitem><para>For formats where the number of bus samples per pixel is larger
-	than 1, an endianness value stating if the pixel is transferred MSB first
-	(BE) or LSB first (LE).</para></listitem>

-      <title>Packed YUV Formats</title>
-
-      <para>Those data formats transfer pixel data as (possibly downsampled) Y, U
-      and V components. Some formats include dummy bits in some of their samples
-      and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma) formats.
-      One cannot rely on the values of these dummy bits as those are undefined.
-      </para>
-      <para>The format code is made of the following information.
-      <itemizedlist>
-	<listitem><para>The Y, U and V components order code, as transferred on the
-	bus. Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
-	dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC formats.
-	</para></listitem>
-	<listitem><para>The number of bits per pixel component. All components are
-	transferred on the same number of bits. Common values are 8, 10 and 12.</para>
-	</listitem>
-	<listitem><para>The number of bus samples per pixel. Pixels that are wider than
-	the bus width must be transferred in multiple samples. Common values are
-	1, 1.5 (encoded as 1_5) and 2.</para></listitem>
-	<listitem><para>The bus width. When the bus width is larger than the number of
-	bits per pixel component, several components are packed in a single bus
-	sample. The components are ordered as specified by the order code, with
-	components on the left of the code transferred in the high order bits.
-	Common values are 8 and 16.</para>
-	</listitem>
-      </itemizedlist>
-      </para>
-
-      <para>For instance, a format where pixels are encoded as 8-bit YUV values
-      downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in the
-      U, Y, V, Y order will be named <constant>MEDIA_BUS_FMT_UYVY8_2X8</constant>.
-      </para>
-
-	<para><xref linkend="v4l2-mbus-pixelcode-yuv8"/> lists existing packed YUV
-	formats and describes the organization of each pixel data in each sample.
-	When a format pattern is split across multiple samples each of the samples
-	in the pattern is described.</para>
-
-	<para>The role of each bit transferred over the bus is identified by one
-	of the following codes.</para>

-
-    <para>This ioctl is used to create buffers for <link linkend="mmap">memory
-mapped</link> or <link linkend="userp">user pointer</link> or <link
-linkend="dmabuf">DMA buffer</link> I/O. It can be used as an alternative or in
-addition to the &VIDIOC-REQBUFS; ioctl, when a tighter
-control over buffers is required. This ioctl can be called multiple times to
-create buffers of different sizes.</para>
-
-    <para>To allocate the device buffers applications must initialize the
-relevant fields of the <structname>v4l2_create_buffers</structname> structure.
-The <structfield>count</structfield> field must be set to the number of
-requested buffers, the <structfield>memory</structfield> field specifies the
-requested I/O method and the <structfield>reserved</structfield> array must be
-zeroed.</para>
-
-    <para>The <structfield>format</structfield> field specifies the image format
-that the buffers must be able to handle. The application has to fill in this
-&v4l2-format;. Usually this will be done using the &VIDIOC-TRY-FMT; or &VIDIOC-G-FMT; ioctls
-to ensure that the requested format is supported by the driver.
-Based on the format's <structfield>type</structfield> field the requested buffer
-size (for single-planar) or plane sizes (for multi-planar formats) will be
-used for the allocated buffers. The driver may return an error if the size(s)
-are not supported by the hardware (usually because they are too small).</para>
-
-    <para>The buffers created by this ioctl will have as minimum size the size
-defined by the <structfield>format.pix.sizeimage</structfield> field (or the
-corresponding fields for other format types). Usually if the
-<structfield>format.pix.sizeimage</structfield> field is less than the minimum
-required for the given format, then an error will be returned since drivers will
-typically not allow this. If it is larger, then the value will be used as-is.
-In other words, the driver may reject the requested size, but if it is accepted
-the driver will use it unchanged.</para>
-
-    <para>When the ioctl is called with a pointer to this structure the driver
-will attempt to allocate up to the requested number of buffers and store the
-actual number allocated and the starting index in the
-<structfield>count</structfield> and the <structfield>index</structfield> fields
-respectively. On return <structfield>count</structfield> can be smaller than
-the number requested.</para>

-(normal playback). A speed of 1 steps just one frame forward, a speed of -1 steps

-

-returns success if the given index value (zero-based) is valid. The

-
-    <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>

-	    <entry>CVT/GTF specific: the timings use reduced blanking (CVT) or the 'Secondary
-GTF' curve (GTF). In both cases the horizontal and/or vertical blanking
-intervals are reduced, allowing a higher resolution over the same

-of six. These formats can be optionally played at 1 / 1.001 speed to
-be compatible with 60 Hz based standards such as NTSC and PAL-M that use a framerate of
-29.97 frames per second. If the transmitter can't generate such frequencies, then the
-flag will also be cleared. This is a read-only flag, applications must not set this.
-	    </entry>
-	  </row>
-	  <row>
-	    <entry>V4L2_DV_FL_REDUCED_FPS</entry>
-	    <entry>CEA-861 specific: only valid for video transmitters, the flag is cleared
-by receivers. It is also only valid for formats with the V4L2_DV_FL_CAN_REDUCE_FPS flag
-set, for other formats the flag will be cleared by the driver.
-
-If the application sets this flag, then the pixelclock used to set up the transmitter is
-divided by 1.001 to make it compatible with NTSC framerates. If the transmitter
-can't generate such frequencies, then the flag will also be cleared.
-	    </entry>
-	  </row>
-	  <row>
-	    <entry>V4L2_DV_FL_HALF_LINE</entry>
-	    <entry>Specific to interlaced formats: if set, then the vertical frontporch
-of field 1 (aka the odd field) is really one half-line longer and the vertical backporch
-of field 2 (aka the even field) is really one half-line shorter, so each field has exactly
-the same number of half-lines. Whether half-lines can be detected or used depends on
-the hardware.
-	    </entry>
-	  </row>
-	  <row>
-	    <entry>V4L2_DV_FL_IS_CE_VIDEO</entry>
-	    <entry>If set, then this is a Consumer Electronics (CE) video format.
-Such formats differ from other formats (commonly called IT formats) in that if
-R'G'B' encoding is used then by default the R'G'B' values use limited range
-(i.e. 16-235) as opposed to full range (i.e. 0-255). All formats defined in CEA-861
-except for the 640x480p59.94 format are CE formats.

-    <para>These ioctls can be used to get or set an EDID associated with an input
-    from a receiver or an output of a transmitter device. They can be
-    used with subdevice nodes (/dev/v4l-subdevX) or with video nodes (/dev/videoX).</para>
-
-    <para>When used with video nodes the <structfield>pad</structfield> field represents the
-    input (for video capture devices) or output (for video output devices) index as
-    is returned by &VIDIOC-ENUMINPUT; and &VIDIOC-ENUMOUTPUT; respectively. When used
-    with subdevice nodes the <structfield>pad</structfield> field represents the
-    input or output pad of the subdevice. If there is no EDID support for the given
-    <structfield>pad</structfield> value, then the &EINVAL; will be returned.</para>
-
-    <para>To get the EDID data the application has to fill in the <structfield>pad</structfield>,
-    <structfield>start_block</structfield>, <structfield>blocks</structfield> and <structfield>edid</structfield>
-    fields, zero the <structfield>reserved</structfield> array and call
-    <constant>VIDIOC_G_EDID</constant>. The current EDID from block
-    <structfield>start_block</structfield> and of size <structfield>blocks</structfield>
-    will be placed in the memory <structfield>edid</structfield> points to. The <structfield>edid</structfield>
-    pointer must point to memory at least <structfield>blocks</structfield>&nbsp;*&nbsp;128 bytes
-    large (the size of one block is 128 bytes).</para>
-
-    <para>If there are fewer blocks than specified, then the driver will set <structfield>blocks</structfield>
-    to the actual number of blocks. If there are no EDID blocks available at all, then the error code
-    ENODATA is set.</para>
-
-    <para>If blocks have to be retrieved from the sink, then this call will block until they
-    have been read.</para>
-
-    <para>If <structfield>start_block</structfield> and <structfield>blocks</structfield> are
-    both set to 0 when <constant>VIDIOC_G_EDID</constant> is called, then the driver will
-    set <structfield>blocks</structfield> to the total number of available EDID blocks
-    and it will return 0 without copying any data. This is an easy way to discover how many
-    EDID blocks there are. Note that if there are no EDID blocks available at all, then
-    the driver will set <structfield>blocks</structfield> to 0 and it returns 0.</para>
-
-    <para>To set the EDID blocks of a receiver the application has to fill in the <structfield>pad</structfield>,
-    <structfield>blocks</structfield> and <structfield>edid</structfield> fields, set
-    <structfield>start_block</structfield> to 0 and zero the <structfield>reserved</structfield> array.
-    It is not possible to set part of an EDID,
-    it is always all or nothing. Setting the EDID data is only valid for receivers as it makes
-    no sense for a transmitter.</para>
-
-    <para>The driver assumes that the full EDID is passed in. If there are more EDID blocks than
-    the hardware can handle then the EDID is not written, but instead the error code E2BIG is set
-    and <structfield>blocks</structfield> is set to the maximum that the hardware supports.
-    If <structfield>start_block</structfield> is any
-    value other than 0 then the error code EINVAL is set.</para>
-
-    <para>To disable an EDID you set <structfield>blocks</structfield> to 0. Depending on the
-    hardware this will drive the hotplug pin low and/or block the source from reading the EDID
-    data in some way. In any case, the end result is the same: the EDID is no longer available.

-
-    <para>To read the data applications must call

-must belong to the same control class.</para>

-<structfield>controls</structfield> and

-<structfield>controls</structfield> fields.</para>
-
-    <para>To get the current value of a set of controls applications
-initialize the <structfield>id</structfield>,
-<structfield>size</structfield> and <structfield>reserved2</structfield> fields
-of each &v4l2-ext-control; and call the
-<constant>VIDIOC_G_EXT_CTRLS</constant> ioctl. String controls controls
-must also set the <structfield>string</structfield> field. Controls
-of compound types (<constant>V4L2_CTRL_FLAG_HAS_PAYLOAD</constant> is set)
-must set the <structfield>ptr</structfield> field.</para>
-
-    <para>If the <structfield>size</structfield> is too small to
-receive the control result (only relevant for pointer-type controls
-like strings), then the driver will set <structfield>size</structfield>
-to a valid value and return an &ENOSPC;. You should re-allocate the
-memory to this new size and try again. For the string type 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>
-
-    <para>N-dimensional arrays are set and retrieved row-by-row. You cannot set a partial
-array, all elements have to be set or retrieved. The total size is calculated
-as <structfield>elems</structfield> * <structfield>elem_size</structfield>.
-These values can be obtained by calling &VIDIOC-QUERY-EXT-CTRL;.</para>
-
-    <para>To change the value of a set of controls applications
-initialize the <structfield>id</structfield>, <structfield>size</structfield>,
-<structfield>reserved2</structfield> and
-<structfield>value/value64/string/ptr</structfield> fields of each &v4l2-ext-control; and

-<structfield>value/value64/string/ptr</structfield> fields of each &v4l2-ext-control; and
-call the <constant>VIDIOC_TRY_EXT_CTRLS</constant> ioctl. It is up to
-the driver whether wrong values are automatically adjusted to a valid
-value or if an error is returned.</para>
-
-    <para>When the <structfield>id</structfield> or
-<structfield>which</structfield> is invalid drivers return an
-&EINVAL;. When the value is out of bounds drivers can choose to take
-the closest valid value or return an &ERANGE;, whatever seems more
-appropriate. In the first case the new value is set in
-&v4l2-ext-control;. If the new control value is inappropriate (e.g. the
-given menu index is not supported by the menu control), then this will
-also result in an &EINVAL; error.</para>
-
-    <para>The driver will only set/get these controls if all control
-values are correct. This prevents the situation where only some of the

-
-<para>Before controls are read from/written to hardware a validation step
-takes place: this checks if all controls in the list are valid controls,
-if no attempt is made to write to a read-only control or read from a write-only
-control, and any other up-front checks that can be done without accessing the

-since some checks might require hardware access for some devices, thus making
-it impossible to do those checks up-front. However, drivers should make a
-best-effort to do as many up-front checks as possible.</para>
-
-<para>This check is done to avoid leaving the hardware in an inconsistent state due
-to easy-to-avoid problems. But it leads to another problem: the application needs to
-know whether an error came from the validation step (meaning that the hardware
-was not touched) or from an error during the actual reading from/writing to hardware.</para>
-
-<para>The, in hindsight quite poor, solution for that is to set <structfield>error_idx</structfield>
-to <structfield>count</structfield> if the validation failed. This has the
-unfortunate side-effect that it is not possible to see which control failed the
-validation. If the validation was successful and the error happened while
-accessing the hardware, then <structfield>error_idx</structfield> is less than
-<structfield>count</structfield> and only the controls up to
-<structfield>error_idx-1</structfield> were read or written correctly, and the
-state of the remaining controls is undefined.</para>
-
-<para>Since <constant>VIDIOC_TRY_EXT_CTRLS</constant> does not access hardware
-there is also no need to handle the validation step in this special way,
-so <structfield>error_idx</structfield> will just be set to the control that
-failed the validation step instead of to <structfield>count</structfield>.
-This means that if <constant>VIDIOC_S_EXT_CTRLS</constant> fails with
-<structfield>error_idx</structfield> set to <structfield>count</structfield>,
-then you can call <constant>VIDIOC_TRY_EXT_CTRLS</constant> to try to discover
-the actual control that failed the validation step. Unfortunately, there
-is no <constant>TRY</constant> equivalent for <constant>VIDIOC_G_EXT_CTRLS</constant>.

-    <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> or
-<constant>V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE</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 either the &v4l2-pix-format; <structfield>pix</structfield> or
-the &v4l2-pix-format-mplane; <structfield>pix_mp</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 <structfield>type</structfield> field is invalid, 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>The format as returned by <constant>VIDIOC_TRY_FMT</constant>
-must be identical to what <constant>VIDIOC_S_FMT</constant> returns for
-the same input or output.</para>

-    <para>The hardware may be able to detect the current DV timings
-automatically, similar to sensing the video standard. To do so, applications
-call <constant>VIDIOC_QUERY_DV_TIMINGS</constant> with a pointer to a
-&v4l2-dv-timings;. Once the hardware detects the timings, it will fill in the
-timings structure.</para>
-
-<para>Please note that drivers shall <emphasis>not</emphasis> switch timings automatically
-if new timings are detected. Instead, drivers should send the
-<constant>V4L2_EVENT_SOURCE_CHANGE</constant> event (if they support this) and expect
-that userspace will take action by calling <constant>VIDIOC_QUERY_DV_TIMINGS</constant>.
-The reason is that new timings usually mean different buffer sizes as well, and you
-cannot change buffer sizes on the fly. In general, applications that receive the

-
-    <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_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 non-compound control, or <errorcode>EINVAL</errorcode>
-if there is none. In addition, the <constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant>
-flag can be specified to enumerate all compound controls (i.e. controls
-with type &ge; <constant>V4L2_CTRL_COMPOUND_TYPES</constant> and/or array
-control, in other words controls that contain more than one value).
-Specify both <constant>V4L2_CTRL_FLAG_NEXT_CTRL</constant> and
-<constant>V4L2_CTRL_FLAG_NEXT_COMPOUND</constant> in order to enumerate
-all controls, compound or not. Drivers which do not support these flags yet
-always return <errorcode>EINVAL</errorcode>.</para>
-
-    <para>The <constant>VIDIOC_QUERY_EXT_CTRL</constant> ioctl was
-introduced in order to better support controls that can use compound
-types, and to expose additional control information that cannot be
-returned in &v4l2-queryctrl; since that structure is full.</para>
-
-    <para><constant>VIDIOC_QUERY_EXT_CTRL</constant> is used in the
-same way as <constant>VIDIOC_QUERYCTRL</constant>, except that the
-<structfield>reserved</structfield> array must be zeroed as well.</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
-<structfield>index</structfield> is invalid. Menu items are enumerated
-by calling <constant>VIDIOC_QUERYMENU</constant> with successive
-<structfield>index</structfield> values from &v4l2-queryctrl;
-<structfield>minimum</structfield> to
-<structfield>maximum</structfield>, inclusive. Note that it is possible
-for <constant>VIDIOC_QUERYMENU</constant> to return an &EINVAL; for some
-indices between <structfield>minimum</structfield> and <structfield>maximum</structfield>.
-In that case that particular menu item is not supported by this driver. Also note that
-the <structfield>minimum</structfield> value is not necessarily 0.</para>

-standard automatically. To do so, applications call <constant>
-VIDIOC_QUERYSTD</constant> with a pointer to a &v4l2-std-id; type. The
-driver stores here a set of candidates, this can be a single flag or a
-set of supported standards if for example the hardware can only
-distinguish between 50 and 60 Hz systems. If no signal was detected,
-then the driver will return V4L2_STD_UNKNOWN. When detection is not
-possible or fails, the set must contain all standards supported by the
-current video input or output.</para>
-
-<para>Please note that drivers shall <emphasis>not</emphasis> switch the video standard
-automatically if a new video standard is detected. Instead, drivers should send the
-<constant>V4L2_EVENT_SOURCE_CHANGE</constant> event (if they support this) and expect
-that userspace will take action by calling <constant>VIDIOC_QUERYSTD</constant>.
-The reason is that a new video standard can mean different buffer sizes as well, and you
-cannot change buffer sizes on the fly. In general, applications that receive the
-Source Change event will have to call <constant>VIDIOC_QUERYSTD</constant>,
-and if the detected video standard is valid they will have to stop streaming, set the new
-standard, allocate new buffers and start streaming again.</para>

-<para>This ioctl is used to initiate <link linkend="mmap">memory mapped</link>,
-<link linkend="userp">user pointer</link> or <link
-linkend="dmabuf">DMABUF</link> based 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 and to setup some internal structures.
-Similarly, DMABUF buffers are allocated by applications through a device
-driver, and this ioctl only configures the driver into DMABUF I/O mode without
-performing any direct allocation.</para>
-
-    <para>To allocate device buffers applications initialize all fields of the
-<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,
-<structfield>memory</structfield> must be set to the requested I/O method and
-the <structfield>reserved</structfield> array must be zeroed. When the ioctl is
-called with a pointer to this structure the driver will attempt to allocate the
-requested number of buffers and it 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 also possible when the driver requires more buffers to function correctly.
-For example video output requires at least two buffers, one displayed and one
-filled by the application.</para>

-returns an &EINVAL;.</para>

-again to change the number of buffers, however this cannot succeed
-when any buffers are still mapped. A <structfield>count</structfield>

-
-    <para>The <constant>VIDIOC_STREAMOFF</constant> ioctl, apart of

-buffers locked in physical memory, and it removes all buffers from the

-not transmitted yet. I/O returns to the same state as after calling
-&VIDIOC-REQBUFS; and can be restarted accordingly.</para>
-

-    <para>This ioctl lets applications enumerate available frame intervals on a

-    can control the frame period on their own. This includes, for instance,
-    image sensors and TV tuners.</para>
-
-    <para>For the common use case of image sensors, the frame intervals
-    available on the sub-device output pad depend on the frame format and size
-    on the same pad. Applications must thus specify the desired format and size
-    when enumerating frame intervals.</para>
-
-    <para>To enumerate frame intervals applications initialize the
-    <structfield>index</structfield>, <structfield>pad</structfield>,
-    <structfield>which</structfield>, <structfield>code</structfield>,
-    <structfield>width</structfield> and <structfield>height</structfield>
-    fields of &v4l2-subdev-frame-interval-enum; and call the
-    <constant>VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL</constant> ioctl with a pointer
-    to this structure. Drivers fill the rest of the structure or return
-    an &EINVAL; if one of the input fields is invalid. All frame intervals are
-    enumerable by beginning at index zero and incrementing by one until
-    <errorcode>EINVAL</errorcode> is returned.</para>
-
-    <para>Available frame intervals may depend on the current 'try' formats
-    at other pads of the sub-device, as well as on the current active links. See
-    &VIDIOC-SUBDEV-G-FMT; for more information about the try formats.</para>
-

- * not change cp0_epc due to the instruction
+/**
+ * struct emuframe - The 'emulation' frame structure
+ * @emul:	The instruction to 'emulate'.
+ * @badinst:	A break instruction to cause a return to the kernel.
  *
- * According to the spec:
- * 1) it shouldn't be a branch :-)
- * 2) it can be a COP instruction :-(
- * 3) if we are tring to run a protected memory space we must take
- *    special care on memory access instructions :-(
+ * This structure defines the frames placed within the delay slot emulation
+ * page in response to a call to mips_dsemul(). Each thread may be allocated
+ * only one frame at any given time. The kernel stores within it the
+ * instruction to be 'emulated' followed by a break instruction, then
+ * executes the frame in user mode. The break causes a trap to the kernel
+ * which leads to do_dsemulret() being called unless the instruction in
+ * @emul causes a trap itself, is a branch, or a signal is delivered to
+ * the thread. In these cases the allocated frame will either be reused by
+ * a subsequent delay slot 'emulation', or be freed during signal delivery or
+ * upon thread exit.
+ *
+ * This approach is used because:
+ *
+ * - Actually emulating all instructions isn't feasible. We would need to
+ *   be able to handle instructions from all revisions of the MIPS ISA,
+ *   all ASEs & all vendor instruction set extensions. This would be a
+ *   whole lot of work & continual maintenance burden as new instructions
+ *   are introduced, and in the case of some vendor extensions may not
+ *   even be possible. Thus we need to take the approach of actually
+ *   executing the instruction.
+ *
+ * - We must execute the instruction within user context. If we were to
+ *   execute the instruction in kernel mode then it would have access to
+ *   kernel resources without very careful checks, leaving us with a
+ *   high potential for security or stability issues to arise.
+ *
+ * - We used to place the frame on the users stack, but this requires
+ *   that the stack be executable. This is bad for security so the
+ *   per-process page is now used instead.
+ *
+ * - The instruction in @emul may be something entirely invalid for a
+ *   delay slot. The user may (intentionally or otherwise) place a branch
+ *   in a delay slot, or a kernel mode instruction, or something else
+ *   which generates an exception. Thus we can't rely upon the break in
+ *   @badinst always being hit. For this reason we track the index of the
+ *   frame allocated to each thread, allowing us to clean it up at later
+ *   points such as signal delivery or thread exit.
+ *
+ * - The user may generate a fake struct emuframe if they wish, invoking
+ *   the BRK_MEMU break instruction themselves. We must therefore not
+ *   trust that BRK_MEMU means there's actually a valid frame allocated
+ *   to the thread, and must not allow the user to do anything they
+ *   couldn't already.

+ * you can see the non-zero bits are divided into several well-separated
+ * blocks.  Hcub can find algorithms for those terms separately, which
+ * can then be shifted and added together.
+ *
+ * Dividing the input into 2, 3 or 4 blocks, Hcub can find solutions
+ * with 10, 9 or 8 adds, respectively, making a total of 11 for the
+ * whole number.
+ *
+ * Using just two large blocks, 0xC3910C8D << 31 in the high bits,
+ * and 0xB583EB in the low bits, produces as good an algorithm as any,
+ * and with one more small shift than alternatives.
+ *
+ * The high bits are a larger number and more work to compute, as well
+ * as needing one extra cycle to shift left 31 bits before the final
+ * addition, so they are the critical path for scheduling.  The low bits
+ * can fit into the scheduling slots left over.

- *	based on Paul Gortmaker's rtc.c device and
- *           Sam Creasey Generic rtc driver
- *
- *	This driver allows use of the real time clock (built into
- *	nearly all computers) from user space. It exports the /dev/rtc
- *	interface supporting various ioctl() and also the /proc/driver/rtc
- *	pseudo-file for status information.
- *
- *	The ioctls can be used to set the interrupt behaviour where
- *	supported.
- *
- *	The /dev/rtc interface will block on reads until an interrupt
- *	has been received. If a RTC interrupt has already happened,
- *	it will output an unsigned long and then block. The output value
- *	contains the interrupt status in the low byte and the number of
- *	interrupts since the last read in the remaining high bytes. The
- *	/dev/rtc interface can also be used with the select(2) call.

+	tristate "Software RDMA over Ethernet (RoCE) driver"
+	depends on INET && PCI && INFINIBAND
+	depends on NET_UDP_TUNNEL
+	---help---
+	This driver implements the InfiniBand RDMA transport over
+	the Linux network stack. It enables a system with a
+	standard Ethernet adapter to interoperate with a RoCE
+	adapter or with another system running the RXE driver.
+	Documentation on InfiniBand and RoCE can be downloaded at
+	www.infinibandta.org and www.openfabrics.org. (See also
+	siw which is a similar software driver for iWARP.)
+
+	The driver is split into two layers, one interfaces with the
+	Linux RDMA stack and implements a kernel or user space
+	verbs API. The user space verbs API requires a support
+	library named librxe which is loaded by the generic user
+	space verbs API, libibverbs. The other layer interfaces
+	with the Linux network stack at layer 3.
+
+	To configure and work with soft-RoCE driver please use the
+	following wiki page under "configure Soft-RoCE (RXE)" section:

+ * that particular node.  If a leaf node is reached, return the records that
+ * intersect the interval.  Note that an interval query may return numerous
+ * entries.  For a non-overlapped tree, simply search for the record associated
+ * with the lowest key and iterate forward until a non-matching record is
+ * found.  Section 14.3 ("Interval Trees") of _Introduction to Algorithms_ by
+ * Cormen, Leiserson, Rivest, and Stein (2nd or 3rd ed. only) discuss this in
+ * more detail.
+ *
+ * Why do we care about overlapping intervals?  Let's say you have a bunch of
+ * reverse mapping records on a reflink filesystem:
+ *
+ * 1: +- file A startblock B offset C length D -----------+
+ * 2:      +- file E startblock F offset G length H --------------+
+ * 3:      +- file I startblock F offset J length K --+
+ * 4:                                                        +- file L... --+
+ *
+ * Now say we want to map block (B+D) into file A at offset (C+D).  Ideally,
+ * we'd simply increment the length of record 1.  But how do we find the record
+ * that ends at (B+D-1) (i.e. record 1)?  A LE lookup of (B+D-1) would return
+ * record 3 because the keys are ordered first by startblock.  An interval
+ * query would return records 1 and 2 because they both overlap (B+D-1), and
+ * from that we can pick out record 1 as the appropriate left neighbor.
+ *
+ * In the non-overlapped case you can do a LE lookup and decrement the cursor
+ * because a record's interval must end before the next record.

+/*
+ * Deferred Operations in XFS
+ *
+ * Due to the way locking rules work in XFS, certain transactions (block
+ * mapping and unmapping, typically) have permanent reservations so that
+ * we can roll the transaction to adhere to AG locking order rules and
+ * to unlock buffers between metadata updates.  Prior to rmap/reflink,
+ * the mapping code had a mechanism to perform these deferrals for
+ * extents that were going to be freed; this code makes that facility
+ * more generic.
+ *
+ * When adding the reverse mapping and reflink features, it became
+ * necessary to perform complex remapping multi-transactions to comply
+ * with AG locking order rules, and to be able to spread a single
+ * refcount update operation (an operation on an n-block extent can
+ * update as many as n records!) among multiple transactions.  XFS can
+ * roll a transaction to facilitate this, but using this facility
+ * requires us to log "intent" items in case log recovery needs to
+ * redo the operation, and to log "done" items to indicate that redo
+ * is not necessary.
+ *
+ * Deferred work is tracked in xfs_defer_pending items.  Each pending
+ * item tracks one type of deferred work.  Incoming work items (which
+ * have not yet had an intent logged) are attached to a pending item
+ * on the dop_intake list, where they wait for the caller to finish
+ * the deferred operations.
+ *
+ * Finishing a set of deferred operations is an involved process.  To
+ * start, we define "rolling a deferred-op transaction" as follows:
+ *
+ * > For each xfs_defer_pending item on the dop_intake list,
+ *   - Sort the work items in AG order.  XFS locking
+ *     order rules require us to lock buffers in AG order.
+ *   - Create a log intent item for that type.
+ *   - Attach it to the pending item.
+ *   - Move the pending item from the dop_intake list to the
+ *     dop_pending list.
+ * > Roll the transaction.
+ *
+ * NOTE: To avoid exceeding the transaction reservation, we limit the
+ * number of items that we attach to a given xfs_defer_pending.
+ *
+ * The actual finishing process looks like this:
+ *
+ * > For each xfs_defer_pending in the dop_pending list,
+ *   - Roll the deferred-op transaction as above.
+ *   - Create a log done item for that type, and attach it to the
+ *     log intent item.
+ *   - For each work item attached to the log intent item,
+ *     * Perform the described action.
+ *     * Attach the work item to the log done item.
+ *
+ * The key here is that we must log an intent item for all pending
+ * work items every time we roll the transaction, and that we must log
+ * a done item as soon as the work is completed.  With this mechanism
+ * we can perform complex remapping operations, chaining intent items
+ * as needed.
+ *
+ * This is an example of remapping the extent (E, E+B) into file X at
+ * offset A and dealing with the extent (C, C+B) already being mapped
+ * there:
+ * +-------------------------------------------------+
+ * | Unmap file X startblock C offset A length B     | t0

+ * Reverse map btree.
+ *
+ * This is a per-ag tree used to track the owner(s) of a given extent. With
+ * reflink it is possible for there to be multiple owners, which is a departure
+ * from classic XFS. Owner records for data extents are inserted when the
+ * extent is mapped and removed when an extent is unmapped.  Owner records for
+ * all other block types (i.e. metadata) are inserted when an extent is
+ * allocated and removed when an extent is freed. There can only be one owner
+ * of a metadata extent, usually an inode or some other metadata structure like
+ * an AG btree.
+ *
+ * The rmap btree is part of the free space management, so blocks for the tree
+ * are sourced from the agfl. Hence we need transaction reservation support for
+ * this tree so that the freelist is always large enough. This also impacts on
+ * the minimum space we need to leave free in the AG.
+ *
+ * The tree is ordered by [ag block, owner, offset]. This is a large key size,
+ * but it is the only way to enforce unique keys when a block can be owned by
+ * multiple files at any offset. There's no need to order/search by extent
+ * size for online updating/management of the tree. It is intended that most
+ * reverse lookups will be to find the owner(s) of a particular block, or to
+ * try to recover tree and file data from corrupt primary metadata.

 'NAME' specifies the name of this argument (optional). You can use the name of local variable, local data structure member (e.g. var->field, var.field2), local array with fixed index (e.g. array[1], var->array[0], var->pointer[2]), or kprobe-tracer argument format (e.g. $retval, %ax, etc). Note that the name of this argument will be set as the last member name if you specify a local data structure member (e.g. field2 for 'var->field1.field2'.)
 '$vars' and '$params' special arguments are also available for NAME, '$vars' is expanded to the local variables (including function parameters) which can access at given probe point. '$params' is expanded to only the function parameters.
-'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo. You can specify 'string' type only for the local variable or structure member which is an array of or a pointer to 'char' or 'unsigned char' type.
+'TYPE' casts the type of this argument (optional). If omitted, perf probe automatically set the type based on debuginfo. Currently, basic types (u8/u16/u32/u64/s8/s16/s32/s64), signedness casting (u/s), "string" and bitfield are supported. (see TYPES for detail)
 
 On x86 systems %REG is always the short form of the register: for example %AX. %RAX or %EAX is not valid.
 
+TYPES
+-----
+Basic types (u8/u16/u32/u64/s8/s16/s32/s64) are integer types. Prefix 's' and 'u' means those types are signed and unsigned respectively. Traced arguments are shown in decimal (signed) or hex (unsigned). You can also use 's' or 'u' to specify only signedness and leave its size auto-detected by perf probe.
+String type is a special type, which fetches a "null-terminated" string from kernel space. This means it will fail and store NULL if the string container has been paged out. You can specify 'string' type only for the local variable or structure member which is an array of or a pointer to 'char' or 'unsigned char' type.
+Bitfield is another special type, which takes 3 parameters, bit-width, bit-offset, and container-size (usually 32). The syntax is;
+
+ b<bit-width>@<bit-offset>/<container-size>
+
