+ </note>
+
+ <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

+ <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>

+ <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

+ <note>For the purpose of this section, the term

+ 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 exemple is shown on
+ <xref linkend="pipeline-scaling" xrefstyle="template: Figure %n" />, 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>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.</listitem>
+ <listitem>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.</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>

+
+ <para>Those data formats transfer pixel data as (possibly downsampled) Y, U
+ and V components. The format code is made of the following information.
+ <itemizedlist>
+ <listitem>The Y, U and V components order code, as transferred on the
+ bus. Possible values are YUYV, UYVY, YVYU and VYUY.</listitem>
+ <listitem>The number of bits per pixel component. All components are
+ transferred on the same number of bits. Common values are 8, 10 and 12.
+ </listitem>
+ <listitem>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.</listitem>
+ <listitem>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.
+ </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>V4L2_MBUS_FMT_UYVY8_2X8</constant>.

+
+ <para>This ioctl allows applications to enumerate all frame sizes
+ supported by a sub-device on the given pad for the given media bus format.
+ Supported formats can be retrieved with the &VIDIOC-SUBDEV-ENUM-MBUS-CODE;
+ ioctl.</para>
+
+ <para>To enumerate frame sizes applications initialize the
+ <structfield>pad</structfield>, <structfield>code</structfield> and
+ <structfield>index</structfield> fields of the
+ &v4l2-subdev-mbus-code-enum; and call the
+ <constant>VIDIOC_SUBDEV_ENUM_FRAME_SIZE</constant> ioctl with a pointer to
+ the structure. Drivers fill the minimum and maximum frame sizes or return
+ an &EINVAL; if one of the input parameters is invalid.</para>
+
+ <para>Sub-devices that only support discrete frame sizes (such as most
+ sensors) will return one or more frame sizes with identical minimum and
+ maximum values.</para>
+
+ <para>Not all possible sizes in given [minimum, maximum] ranges need to be
+ supported. For instance, a scaler that uses a fixed-point scaling ratio
+ might not be able to produce every frame size between the minimum and
+ maximum values. Applications must use the &VIDIOC-SUBDEV-S-FMT; ioctl to
+ try the sub-device for an exact supported frame size.</para>
+
+ <para>Available frame sizes may depend on the current 'try' formats at other
+ pads of the sub-device, as well as on the current active links and the
+ current values of V4L2 controls. See &VIDIOC-SUBDEV-G-FMT; for more
+ information about try formats.</para>

+
+ <para>These ioctls are used to negotiate the frame format at specific
+ subdev pads in the image pipeline.</para>
+
+ <para>To retrieve the current format applications set the
+ <structfield>pad</structfield> field of a &v4l2-subdev-format; to the
+ desired pad number as reported by the media API and the
+ <structfield>which</structfield> field to
+ <constant>V4L2_SUBDEV_FORMAT_ACTIVE</constant>. When they call the
+ <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl with a pointer to this
+ structure the driver fills the members of the <structfield>format</structfield>
+ field.</para>
+
+ <para>To change the current format applications set both the
+ <structfield>pad</structfield> and <structfield>which</structfield> fields
+ and all members of the <structfield>format</structfield> field. When they
+ call the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl with a pointer to this
+ structure the driver verifies the requested format, adjusts it based on the
+ hardware capabilities and configures the device. Upon return the
+ &v4l2-subdev-format; contains the current format as would be returned by a
+ <constant>VIDIOC_SUBDEV_G_FMT</constant> call.</para>
+
+ <para>Applications can query the device capabilities by setting the
+ <structfield>which</structfield> to
+ <constant>V4L2_SUBDEV_FORMAT_TRY</constant>. When set, 'try' formats are not
+ applied to the device by the driver, but are changed exactly as active
+ formats and stored in the sub-device file handle. Two applications querying
+ the same sub-device would thus not interact with each other.</para>
+
+ <para>For instance, to try a format at the output pad of a sub-device,
+ applications would first set the try format at the sub-device input with the
+ <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl. They would then either
+ retrieve the default format at the output pad with the
+ <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl, or set the desired output
+ pad format with the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl and check
+ the returned value.</para>
+
+ <para>Try formats do not depend on active formats, but can depend on the
+ current links configuration or sub-device controls value. For instance, a
+ low-pass noise filter might crop pixels at the frame boundaries, modifying
+ its output frame size.</para>
+
+ <para>Drivers must not return an error solely because the requested format
+ doesn't match the device capabilities. They must instead modify the format
+ to match what the hardware can provide. The modified format should be as
+ close as possible to the original request.</para>
