[media] v4l: v4l2_subdev userspace format API
Add a userspace API to get, set and enumerate the media format on a subdev pad. The format at the output of a subdev usually depends on the format at its input(s). The try format operation is thus not suitable for probing format at individual pads, as it can't modify the device state and thus can't remember the format tried at the input to compute the output format. To fix the problem, pass an extra argument to the get/set format operations to select the 'try' or 'active' format. The try format is used when probing the subdev. Setting the try format must not change the device configuration but can store data for later reuse. Data storage is provided at the file-handle level so applications probing the subdev concurently won't interfere with each other. The active format is used when configuring the subdev. It's identical to the format handled by the usual get/set operations.

9 <para>The complex nature of V4L2 devices, where hardware is often made of
10 several integrated circuits that need to interact with each other in a
11 controlled way, leads to complex V4L2 drivers. The drivers usually reflect
12 the hardware model in software, and model the different hardware components
13 as software blocks called sub-devices.</para>

15 <para>V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
16 implements the media device API, they will automatically inherit from media
17 entities. Applications will be able to enumerate the sub-devices and discover

19 API.</para>

36 <title>Controls</title>
37 <para>Most V4L2 controls are implemented by sub-device hardware. Drivers
38 usually merge all controls and expose them through video device nodes.
39 Applications can control all sub-devices through a single interface.</para>
40
41 <para>Complex devices sometimes implement the same control in different
42 pieces of hardware. This situation is common in embedded platforms, where
43 both sensors and image processing hardware implement identical functions,
44 such as contrast adjustment, white balance or faulty pixels correction. As
45 the V4L2 controls API doesn't support several identical controls in a single
46 device, all but one of the identical controls are hidden.</para>
47
48 <para>Applications can access those hidden controls through the sub-device
49 node with the V4L2 control API described in <xref linkend="control" />. The
50 ioctls behave identically as when issued on V4L2 device nodes, with the
51 exception that they deal only with controls implemented in the sub-device.

60 <para>V4L2 sub-devices can notify applications of events as described in

63 the sub-device. Depending on the driver, those events might also be reported
64 on one (or several) V4L2 device nodes.</para>

74
75 <note>For the purpose of this section, the term

78
79 <para>Image formats are typically negotiated on video capture and output

81 The driver is responsible for configuring every block in the video pipeline
82 according to the requested format at the pipeline input and/or
83 output.</para>
84
85 <para>For complex devices, such as often found in embedded systems,
86 identical image sizes at the output of a pipeline can be achieved using
87 different hardware configurations. One such exemple is shown on

107 <para>The sensor scaler is usually of less quality than the host scaler, but
108 scaling on the sensor is required to achieve higher frame rates. Depending
109 on the use case (quality vs. speed), the pipeline must be configured
110 differently. Applications need to configure the formats at every point in
111 the pipeline explicitly.</para>
112
113 <para>Drivers that implement the <link linkend="media-controller-intro">media
114 API</link> can expose pad-level image format configuration to applications.
115 When they do, applications can use the &VIDIOC-SUBDEV-G-FMT; and
116 &VIDIOC-SUBDEV-S-FMT; ioctls. to negotiate formats on a per-pad basis.</para>
117
118 <para>Applications are responsible for configuring coherent parameters on
119 the whole pipeline and making sure that connected pads have compatible
120 formats. The pipeline is checked for formats mismatch at &VIDIOC-STREAMON;
121 time, and an &EPIPE; is then returned if the configuration is
122 invalid.</para>
123
124 <para>Pad-level image format configuration support can be tested by calling
125 the &VIDIOC-SUBDEV-G-FMT; ioctl on pad 0. If the driver returns an &EINVAL;
126 pad-level format configuration is not supported by the sub-device.</para>
127
128 <section>
129 <title>Format Negotiation</title>
130
131 <para>Acceptable formats on pads can (and usually do) depend on a number
132 of external parameters, such as formats on other pads, active links, or
133 even controls. Finding a combination of formats on all pads in a video
134 pipeline, acceptable to both application and driver, can't rely on formats
135 enumeration only. A format negotiation mechanism is required.</para>
136
137 <para>Central to the format negotiation mechanism are the get/set format
138 operations. When called with the <structfield>which</structfield> argument
139 set to <constant>V4L2_SUBDEV_FORMAT_TRY</constant>, the
140 &VIDIOC-SUBDEV-G-FMT; and &VIDIOC-SUBDEV-S-FMT; ioctls operate on a set of
141 formats parameters that are not connected to the hardware configuration.
142 Modifying those 'try' formats leaves the device state untouched (this
143 applies to both the software state stored in the driver and the hardware
144 state stored in the device itself).</para>
145
146 <para>While not kept as part of the device state, try formats are stored
147 in the sub-device file handles. A &VIDIOC-SUBDEV-G-FMT; call will return
148 the last try format set <emphasis>on the same sub-device file
149 handle</emphasis>. Several applications querying the same sub-device at
150 the same time will thus not interact with each other.</para>
151
152 <para>To find out whether a particular format is supported by the device,
153 applications use the &VIDIOC-SUBDEV-S-FMT; ioctl. Drivers verify and, if
154 needed, change the requested <structfield>format</structfield> based on
155 device requirements and return the possibly modified value. Applications
156 can then choose to try a different format or accept the returned value and
157 continue.</para>
158
159 <para>Formats returned by the driver during a negotiation iteration are
160 guaranteed to be supported by the device. In particular, drivers guarantee
161 that a returned format will not be further changed if passed to an
162 &VIDIOC-SUBDEV-S-FMT; call as-is (as long as external parameters, such as
163 formats on other pads or links' configuration are not changed).</para>
164
165 <para>Drivers automatically propagate formats inside sub-devices. When a
166 try or active format is set on a pad, corresponding formats on other pads
167 of the same sub-device can be modified by the driver. Drivers are free to
168 modify formats as required by the device. However, they should comply with
169 the following rules when possible:
170 <itemizedlist>
171 <listitem>Formats should be propagated from sink pads to source pads.
172 Modifying a format on a source pad should not modify the format on any
173 sink pad.</listitem>
174 <listitem>Sub-devices that scale frames using variable scaling factors
175 should reset the scale factors to default values when sink pads formats
176 are modified. If the 1:1 scaling ratio is supported, this means that
177 source pads formats should be reset to the sink pads formats.</listitem>
178 </itemizedlist>
179 </para>
180
181 <para>Formats are not propagated across links, as that would involve
182 propagating them from one sub-device file handle to another. Applications
183 must then take care to configure both ends of every link explicitly with
184 compatible formats. Identical formats on the two ends of a link are
185 guaranteed to be compatible. Drivers are free to accept different formats
186 matching device requirements as being compatible.</para>

271 during format negotiation, applications should negotiate try formats first
272 and then modify the active settings using the try formats returned during
273 the last negotiation iteration. This guarantees that the active format
274 will be applied as-is by the driver without being modified.

47 <title>Media Bus Pixel Codes</title>
48
49 <para>The media bus pixel codes describe image formats as flowing over
50 physical busses (both between separate physical components and inside SoC
51 devices). This should not be confused with the V4L2 pixel formats that
52 describe, using four character codes, image formats as stored in memory.
53 </para>
54
55 <para>While there is a relationship between image formats on busses and
56 image formats in memory (a raw Bayer image won't be magically converted to
57 JPEG just by storing it to memory), there is no one-to-one correspondance
58 between them.</para>
59
60 <section>
61 <title>Packed RGB Formats</title>
62
63 <para>Those formats transfer pixel data as red, green and blue components.
64 The format code is made of the following information.
65 <itemizedlist>
66 <listitem>The red, green and blue components order code, as encoded in a
67 pixel sample. Possible values are RGB and BGR.</listitem>
68 <listitem>The number of bits per component, for each component. The values
69 can be different for all components. Common values are 555 and 565.
70 </listitem>
71 <listitem>The number of bus samples per pixel. Pixels that are wider than
72 the bus width must be transferred in multiple samples. Common values are
73 1 and 2.</listitem>
74 <listitem>The bus width.</listitem>
75 <listitem>For formats where the total number of bits per pixel is smaller
76 than the number of bus samples per pixel times the bus width, a padding
77 value stating if the bytes are padded in their most high order bits
78 (PADHI) or low order bits (PADLO).</listitem>
79 <listitem>For formats where the number of bus samples per pixel is larger
80 than 1, an endianness value stating if the pixel is transferred MSB first
81 (BE) or LSB first (LE).</listitem>
82 </itemizedlist>
83 </para>
84
85 <para>For instance, a format where pixels are encoded as 5-bits red, 5-bits
86 green and 5-bit blue values padded on the high bit, transferred as 2 8-bit
87 samples per pixel with the most significant bits (padding, red and half of
88 the green value) transferred first will be named

784 <listitem>The bus width. When the bus width is larger than the number of
785 bits per pixel component, several components are packed in a single bus
786 sample. The components are ordered as specified by the order code, with
787 components on the left of the code transferred in the high order bits.

58 <para>This ioctl allows applications to enumerate all frame sizes
59 supported by a sub-device on the given pad for the given media bus format.
60 Supported formats can be retrieved with the &VIDIOC-SUBDEV-ENUM-MBUS-CODE;
61 ioctl.</para>
62
63 <para>To enumerate frame sizes applications initialize the
64 <structfield>pad</structfield>, <structfield>code</structfield> and
65 <structfield>index</structfield> fields of the
66 &v4l2-subdev-mbus-code-enum; and call the
67 <constant>VIDIOC_SUBDEV_ENUM_FRAME_SIZE</constant> ioctl with a pointer to
68 the structure. Drivers fill the minimum and maximum frame sizes or return
69 an &EINVAL; if one of the input parameters is invalid.</para>
70
71 <para>Sub-devices that only support discrete frame sizes (such as most
72 sensors) will return one or more frame sizes with identical minimum and
73 maximum values.</para>
74
75 <para>Not all possible sizes in given [minimum, maximum] ranges need to be
76 supported. For instance, a scaler that uses a fixed-point scaling ratio
77 might not be able to produce every frame size between the minimum and
78 maximum values. Applications must use the &VIDIOC-SUBDEV-S-FMT; ioctl to
79 try the sub-device for an exact supported frame size.</para>
80
81 <para>Available frame sizes may depend on the current 'try' formats at other
82 pads of the sub-device, as well as on the current active links and the
83 current values of V4L2 controls. See &VIDIOC-SUBDEV-G-FMT; for more
84 information about try formats.</para>

59 <para>These ioctls are used to negotiate the frame format at specific
60 subdev pads in the image pipeline.</para>
61
62 <para>To retrieve the current format applications set the
63 <structfield>pad</structfield> field of a &v4l2-subdev-format; to the
64 desired pad number as reported by the media API and the
65 <structfield>which</structfield> field to
66 <constant>V4L2_SUBDEV_FORMAT_ACTIVE</constant>. When they call the
67 <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl with a pointer to this
68 structure the driver fills the members of the <structfield>format</structfield>
69 field.</para>
70
71 <para>To change the current format applications set both the
72 <structfield>pad</structfield> and <structfield>which</structfield> fields
73 and all members of the <structfield>format</structfield> field. When they
74 call the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl with a pointer to this
75 structure the driver verifies the requested format, adjusts it based on the
76 hardware capabilities and configures the device. Upon return the
77 &v4l2-subdev-format; contains the current format as would be returned by a
78 <constant>VIDIOC_SUBDEV_G_FMT</constant> call.</para>
79
80 <para>Applications can query the device capabilities by setting the
81 <structfield>which</structfield> to
82 <constant>V4L2_SUBDEV_FORMAT_TRY</constant>. When set, 'try' formats are not
83 applied to the device by the driver, but are changed exactly as active
84 formats and stored in the sub-device file handle. Two applications querying
85 the same sub-device would thus not interact with each other.</para>
86
87 <para>For instance, to try a format at the output pad of a sub-device,
88 applications would first set the try format at the sub-device input with the

90 retrieve the default format at the output pad with the
91 <constant>VIDIOC_SUBDEV_G_FMT</constant> ioctl, or set the desired output
92 pad format with the <constant>VIDIOC_SUBDEV_S_FMT</constant> ioctl and check

95 <para>Try formats do not depend on active formats, but can depend on the
96 current links configuration or sub-device controls value. For instance, a
97 low-pass noise filter might crop pixels at the frame boundaries, modifying
98 its output frame size.</para>

100 <para>Drivers must not return an error solely because the requested format
101 doesn't match the device capabilities. They must instead modify the format
102 to match what the hardware can provide. The modified format should be as
103 close as possible to the original request.</para>
