<note>
<title>Experimental</title>
<para>This is an <link linkend="experimental">experimental</link>
interface and may change in the future.</para>
</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
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

<section>
<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
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 <link linkend="crop">cropping and scaling</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>

<section>
<title>Cropping and scaling</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 a video sensor or 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>The crop rectangle is retrieved and set using the
&VIDIOC-SUBDEV-G-CROP; and &VIDIOC-SUBDEV-S-CROP; ioctls. Like for pad
formats, drivers store try and active crop rectangles. The format
negotiation mechanism applies to crop settings as well.</para>
<para>On input pads, cropping is applied relatively 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. The crop rectangle be entirely containted
inside the input image size.</para>
<para>Input crop rectangle are reset to their default value when the input
image format is modified. Drivers should use the input image size as the
crop rectangle default value, but hardware requirements may prevent this.
</para>
<para>Cropping behaviour on output pads is not defined.</para>

<title>Media Controller API</title>
<chapter id="media_controller">
<title>Media Controller</title>
<section id="media-controller-intro">
<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>
</section>
<section id="media-controller-model">
<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 are modelled as an oriented graph of building blocks called entities
connected through pads.</para>
<para>An entity 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>
<para>A pad is a 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>
<para>A link 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>

non contiguous in memory. </refpurpose>
</refnamediv>
<refsect1>
<title>Description</title>
<para>This is a multi-planar, two-plane version of the YUV 4:2:0 format.
The three components are separated into two sub-images or planes.
<constant>V4L2_PIX_FMT_NV12M</constant> differs from <constant>V4L2_PIX_FMT_NV12
</constant> in that the two planes are non-contiguous in memory, i.e. the chroma
plane do not necessarily immediately follows the luma plane.
The luminance data occupies the first plane. The Y plane has one byte per pixel.
In the second plane there is a chrominance data with alternating chroma samples.
The CbCr plane is the same width, in bytes, as the Y plane (and of the image),
but is half as tall in pixels. Each CbCr pair belongs to four pixels. For example,
Cb<subscript>0</subscript>/Cr<subscript>0</subscript> belongs to
Y'<subscript>00</subscript>, Y'<subscript>01</subscript>,
Y'<subscript>10</subscript>, Y'<subscript>11</subscript>. </para>
<para><constant>V4L2_PIX_FMT_NV12M</constant> is intended to be
used only in drivers and applications that support the multi-planar API,
described in <xref linkend="planar-apis"/>. </para>
<para>If the Y plane has pad bytes after each row, then the
CbCr plane has as many pad bytes after its rows.</para>

The requirement that width is multiple of 128 is implemented because,
the Z shape cannot be cut in half horizontally. In case the vertical resolution
of macroblocks is odd then the last row of macroblocks is arranged in a linear
order. </para>

<para>The following four pixel formats are raw sRGB / Bayer formats with
12 bits per colour. Each colour component is stored in a 16-bit word, with 6
unused high bits filled with zeros. Each n-pixel row contains n/2 green samples
and n/2 blue or red samples, with alternating red and blue rows. Bytes are
stored in memory in little endian order. They are conventionally described
as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example of one of these
formats</para>

<title>Description</title>
<para>This is a multi-planar format, as opposed to a packed format.
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 data
constitutes the second plane which is half the width and half
the height of the Y plane (and of the image). Each Cb belongs to four
pixels, a two-by-two square of the image. For example,
Cb<subscript>0</subscript> belongs to Y'<subscript>00</subscript>,
Y'<subscript>01</subscript>, Y'<subscript>10</subscript>, and
Y'<subscript>11</subscript>. The Cr data, just like the Cb plane, is
in the third plane. </para>
<para>If the Y plane has pad bytes after each row, then the Cb
and Cr planes have half as many pad bytes after their rows. In other
words, two Cx rows (including padding) is exactly as long as one Y row
(including padding).</para>
<para><constant>V4L2_PIX_FMT_NV12M</constant> is intended to be
used only in drivers and applications that support the multi-planar API,
described in <xref linkend="planar-apis"/>. </para>

<para>Some devices require data for each input or output video frame
to be placed in discontiguous memory buffers. In such cases, one
video frame has to be addressed using more than one memory address, i.e. one
pointer per "plane". A plane is a sub-buffer of the current frame. For

<para>Some of the V4L2 API calls and structures are interpreted differently,
depending on whether single- or multi-planar API is being used. An application
can choose whether to use one or the other by passing a corresponding buffer
type to its ioctl calls. Multi-planar versions of buffer types are suffixed
with an `_MPLANE' string. For a list of available multi-planar buffer types

<para>This ioctl lets applications enumerate available frame intervals on a
given sub-device pad. Frame intervals only makes sense for sub-devices that
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>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>
<para>Sub-devices that support the frame interval enumeration ioctl should
implemented it on a single pad only. Its behaviour when supported on
multiple pads of the same sub-device is not defined.</para>

<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>

Files: drivers/staging/se401/* drivers/staging/usbvideo/*
Check: drivers/staging/se401/se401.c drivers/staging/usbvideo/usbvideo.c
Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
of the kernel. Those drivers will be moved to staging on 2.6.38 and, if nobody
cares enough to port and test them with V4L2 API, they'll be removed on 2.6.39.

What: Video4Linux: Remove obsolete ioctl's
When: kernel 2.6.39
Files: include/media/videodev2.h
Why: Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:
#define VIDIOC_OVERLAY_OLD _IOWR('V', 14, int)
#define VIDIOC_S_PARM_OLD _IOW('V', 22, struct v4l2_streamparm)
#define VIDIOC_S_CTRL_OLD _IOW('V', 28, struct v4l2_control)
#define VIDIOC_G_AUDIO_OLD _IOWR('V', 33, struct v4l2_audio)
#define VIDIOC_G_AUDOUT_OLD _IOWR('V', 49, struct v4l2_audioout)
#define VIDIOC_CROPCAP_OLD _IOR('V', 58, struct v4l2_cropcap)
There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.

Linux kernel media framework
============================
This document describes the Linux kernel media framework, its data structures,
functions and their usage.
Introduction
------------
The media controller API is documented in DocBook format in
Documentation/DocBook/v4l/media-controller.xml. This document will focus on
the kernel-side implementation of the media framework.
Abstract media device model
---------------------------
Discovering a device internal topology, and configuring it at runtime, is one
of the goals of the media framework. To achieve this, hardware devices are
modeled as an oriented graph of building blocks called entities connected
through pads.
An entity is a basic media hardware 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.
A pad is a 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.
A link 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.
Media device
------------
A media device is represented by a struct media_device instance, defined in
include/media/media-device.h. Allocation of the structure is handled by the
media device driver, usually by embedding the media_device instance in a
larger driver-specific structure.
Drivers register media device instances by calling
media_device_register(struct media_device *mdev);
The caller is responsible for initializing the media_device structure before
registration. The following fields must be set:
- dev must point to the parent device (usually a pci_dev, usb_interface or
platform_device instance).
- model must be filled with the device model name as a NUL-terminated UTF-8
string. The device/model revision must not be stored in this field.
The following fields are optional:
- serial is a unique serial number stored as a NUL-terminated ASCII string.
The field is big enough to store a GUID in text form. If the hardware
doesn't provide a unique serial number this field must be left empty.
- bus_info represents the location of the device in the system as a
NUL-terminated ASCII string. For PCI/PCIe devices bus_info must be set to
"PCI:" (or "PCIe:") followed by the value of pci_name(). For USB devices,
the usb_make_path() function must be used. This field is used by
applications to distinguish between otherwise identical devices that don't
provide a serial number.
- hw_revision is the hardware device revision in a driver-specific format.
When possible the revision should be formatted with the KERNEL_VERSION
macro.
- driver_version is formatted with the KERNEL_VERSION macro. The version
minor must be incremented when new features are added to the userspace API
without breaking binary compatibility. The version major must be
incremented when binary compatibility is broken.
Upon successful registration a character device named media[0-9]+ is created.
The device major and minor numbers are dynamic. The model name is exported as
a sysfs attribute.
Drivers unregister media device instances by calling
media_device_unregister(struct media_device *mdev);
Unregistering a media device that hasn't been registered is *NOT* safe.
Entities, pads and links
------------------------
- Entities
Entities are represented by a struct media_entity instance, defined in
include/media/media-entity.h. The structure is usually embedded into a
higher-level structure, such as a v4l2_subdev or video_device instance,
although drivers can allocate entities directly.
Drivers initialize entities by calling
media_entity_init(struct media_entity *entity, u16 num_pads,
struct media_pad *pads, u16 extra_links);
The media_entity name, type, flags, revision and group_id fields can be
initialized before or after calling media_entity_init. Entities embedded in
higher-level standard structures can have some of those fields set by the
higher-level framework.
As the number of pads is known in advance, the pads array is not allocated
dynamically but is managed by the entity driver. Most drivers will embed the
pads array in a driver-specific structure, avoiding dynamic allocation.
Drivers must set the direction of every pad in the pads array before calling
media_entity_init. The function will initialize the other pads fields.
Unlike the number of pads, the total number of links isn't always known in
advance by the entity driver. As an initial estimate, media_entity_init
pre-allocates a number of links equal to the number of pads plus an optional
number of extra links. The links array will be reallocated if it grows beyond
the initial estimate.
Drivers register entities with a media device by calling
media_device_register_entity(struct media_device *mdev,
struct media_entity *entity);
Entities are identified by a unique positive integer ID. Drivers can provide an
ID by filling the media_entity id field prior to registration, or request the
media controller framework to assign an ID automatically. Drivers that provide
IDs manually must ensure that all IDs are unique. IDs are not guaranteed to be
contiguous even when they are all assigned automatically by the framework.
Drivers unregister entities by calling
media_device_unregister_entity(struct media_entity *entity);
Unregistering an entity will not change the IDs of the other entities, and the
ID will never be reused for a newly registered entity.
When a media device is unregistered, all its entities are unregistered
automatically. No manual entities unregistration is then required.
Drivers free resources associated with an entity by calling
media_entity_cleanup(struct media_entity *entity);
This function must be called during the cleanup phase after unregistering the
entity. Note that the media_entity instance itself must be freed explicitly by
the driver if required.
Entities have flags that describe the entity capabilities and state.
MEDIA_ENT_FL_DEFAULT indicates the default entity for a given type.
This can be used to report the default audio and video devices or the
default camera sensor.
Logical entity groups can be defined by setting the group ID of all member
entities to the same non-zero value. An entity group serves no purpose in the
kernel, but is reported to userspace during entities enumeration. The group_id
field belongs to the media device driver and must not by touched by entity
drivers.
Media device drivers should define groups if several entities are logically
bound together. Example usages include reporting
- ALSA, VBI and video nodes that carry the same media stream
- lens and flash controllers associated with a sensor
- Pads
Pads are represented by a struct media_pad instance, defined in
include/media/media-entity.h. Each entity stores its pads in a pads array
managed by the entity driver. Drivers usually embed the array in a
driver-specific structure.
Pads are identified by their entity and their 0-based index in the pads array.
Both information are stored in the media_pad structure, making the media_pad
pointer the canonical way to store and pass link references.
Pads have flags that describe the pad capabilities and state.
MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
One and only one of MEDIA_PAD_FL_SINK and MEDIA_PAD_FL_SOURCE must be set for
each pad.
- Links
Links are represented by a struct media_link instance, defined in
include/media/media-entity.h. Each entity stores all links originating at or
targetting any of its pads in a links array. A given link is thus stored
twice, once in the source entity and once in the target entity. The array is
pre-allocated and grows dynamically as needed.
Drivers create links by calling
media_entity_create_link(struct media_entity *source, u16 source_pad,
struct media_entity *sink, u16 sink_pad,
u32 flags);
An entry in the link array of each entity is allocated and stores pointers
to source and sink pads.
Links have flags that describe the link capabilities and state.
MEDIA_LNK_FL_ENABLED indicates that the link is enabled and can be used
to transfer media data. When two or more links target a sink pad, only
one of them can be enabled at a time.
MEDIA_LNK_FL_IMMUTABLE indicates that the link enabled state can't be
modified at runtime. If MEDIA_LNK_FL_IMMUTABLE is set, then
MEDIA_LNK_FL_ENABLED must also be set since an immutable link is always
enabled.
Graph traversal
---------------
The media framework provides APIs to iterate over entities in a graph.
To iterate over all entities belonging to a media device, drivers can use the
media_device_for_each_entity macro, defined in include/media/media-device.h.
struct media_entity *entity;
media_device_for_each_entity(entity, mdev) {
/* entity will point to each entity in turn */
...
}
Drivers might also need to iterate over all entities in a graph that can be
reached only through enabled links starting at a given entity. The media
framework provides a depth-first graph traversal API for that purpose.
Note that graphs with cycles (whether directed or undirected) are *NOT*
supported by the graph traversal API. To prevent infinite loops, the graph
traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
currently defined as 16.
Drivers initiate a graph traversal by calling
media_entity_graph_walk_start(struct media_entity_graph *graph,
struct media_entity *entity);
The graph structure, provided by the caller, is initialized to start graph
traversal at the given entity.
Drivers can then retrieve the next entity by calling
media_entity_graph_walk_next(struct media_entity_graph *graph);
When the graph traversal is complete the function will return NULL.
Graph traversal can be interrupted at any moment. No cleanup function call is
required and the graph structure can be freed normally.
Helper functions can be used to find a link between two given pads, or a pad
connected to another pad through an enabled link
media_entity_find_link(struct media_pad *source,
struct media_pad *sink);
media_entity_remote_source(struct media_pad *pad);
Refer to the kerneldoc documentation for more information.
Use count and power handling
----------------------------
Due to the wide differences between drivers regarding power management needs,
the media controller does not implement power management. However, the
media_entity structure includes a use_count field that media drivers can use to
track the number of users of every entity for power management needs.
The use_count field is owned by media drivers and must not be touched by entity
drivers. Access to the field must be protected by the media device graph_mutex
lock.
Links setup
-----------
Link properties can be modified at runtime by calling
media_entity_setup_link(struct media_link *link, u32 flags);
The flags argument contains the requested new link flags.
The only configurable property is the ENABLED link flag to enable/disable a
link. Links marked with the IMMUTABLE link flag can not be enabled or disabled.
When a link is enabled or disabled, the media framework calls the
link_setup operation for the two entities at the source and sink of the link,
in that order. If the second link_setup call fails, another link_setup call is
made on the first entity to restore the original link flags.
Media device drivers can be notified of link setup operations by setting the
media_device::link_notify pointer to a callback function. If provided, the
notification callback will be called before enabling and after disabling
links.
Entity drivers must implement the link_setup operation if any of their links
is non-immutable. The operation must either configure the hardware or store
the configuration information to be applied later.
Link configuration must not have any side effect on other links. If an enabled
link at a sink pad prevents another link at the same pad from being disabled,
the link_setup operation must return -EBUSY and can't implicitly disable the
first enabled link.
Pipelines and media streams
---------------------------
When starting streaming, drivers must notify all entities in the pipeline to
prevent link states from being modified during streaming by calling
media_entity_pipeline_start(struct media_entity *entity,
struct media_pipeline *pipe);
The function will mark all entities connected to the given entity through
enabled links, either directly or indirectly, as streaming.
The media_pipeline instance pointed to by the pipe argument will be stored in
every entity in the pipeline. Drivers should embed the media_pipeline structure
in higher-level pipeline structures and can then access the pipeline through
the media_entity pipe field.
Calls to media_entity_pipeline_start() can be nested. The pipeline pointer must
be identical for all nested calls to the function.
When stopping the stream, drivers must notify the entities with
media_entity_pipeline_stop(struct media_entity *entity);
If multiple calls to media_entity_pipeline_start() have been made the same
number of media_entity_pipeline_stop() calls are required to stop streaming. The
media_entity pipe field is reset to NULL on the last nested stop call.
Link configuration will fail with -EBUSY by default if either end of the link is
a streaming entity. Links that can be modified while streaming must be marked
with the MEDIA_LNK_FL_DYNAMIC flag.
If other operations need to be disallowed on streaming entities (such as
changing entities configuration parameters) drivers can explictly check the
media_entity stream_count field to find out if an entity is streaming. This
operation must be done with the media_device graph_mutex held.

OMAP 3 Image Signal Processor (ISP) driver

Introduction
============
This file documents the Texas Instruments OMAP 3 Image Signal Processor (ISP)
driver located under drivers/media/video/omap3isp. The original driver was
written by Texas Instruments but since that it has been rewritten (twice) at
Nokia.
The driver has been successfully used on the following versions of OMAP 3:
3430
3530
3630
The driver implements V4L2, Media controller and v4l2_subdev interfaces.
Sensor, lens and flash drivers using the v4l2_subdev interface in the kernel
are supported.
Split to subdevs
================
The OMAP 3 ISP is split into V4L2 subdevs, each of the blocks inside the ISP
having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
interface to userspace.
OMAP3 ISP CCP2
OMAP3 ISP CSI2a
OMAP3 ISP CCDC
OMAP3 ISP preview
OMAP3 ISP resizer
OMAP3 ISP AEWB
OMAP3 ISP AF
OMAP3 ISP histogram
Each possible link in the ISP is modelled by a link in the Media controller
interface. For an example program see [2].
Controlling the OMAP 3 ISP
==========================
In general, the settings given to the OMAP 3 ISP take effect at the beginning
of the following frame. This is done when the module becomes idle during the
vertical blanking period on the sensor. In memory-to-memory operation the pipe
is run one frame at a time. Applying the settings is done between the frames.
All the blocks in the ISP, excluding the CSI-2 and possibly the CCP2 receiver,
insist on receiving complete frames. Sensors must thus never send the ISP
partial frames.
Autoidle does have issues with some ISP blocks on the 3430, at least.
Autoidle is only enabled on 3630 when the omap3isp module parameter autoidle
is non-zero.
Events
======
The OMAP 3 ISP driver does support the V4L2 event interface on CCDC and
statistics (AEWB, AF and histogram) subdevs.
The CCDC subdev produces V4L2_EVENT_OMAP3ISP_HS_VS type event on HS_VS
interrupt which is used to signal frame start. The event is triggered exactly
when the reception of the first line of the frame starts in the CCDC module.
The event can be subscribed on the CCDC subdev.
(When using parallel interface one must pay account to correct configuration
of the VS signal polarity. This is automatically correct when using the serial
receivers.)
Each of the statistics subdevs is able to produce events. An event is
generated whenever a statistics buffer can be dequeued by a user space
application using the VIDIOC_OMAP3ISP_STAT_REQ IOCTL. The events available
are:
V4L2_EVENT_OMAP3ISP_AEWB
V4L2_EVENT_OMAP3ISP_AF
V4L2_EVENT_OMAP3ISP_HIST
The type of the event data is struct omap3isp_stat_event_status for these
ioctls. If there is an error calculating the statistics, there will be an
event as usual, but no related statistics buffer. In this case
omap3isp_stat_event_status.buf_err is set to non-zero.
Private IOCTLs
==============
The OMAP 3 ISP driver supports standard V4L2 IOCTLs and controls where
possible and practical. Much of the functions provided by the ISP, however,
does not fall under the standard IOCTLs --- gamma tables and configuration of
statistics collection are examples of such.
In general, there is a private ioctl for configuring each of the blocks
containing hardware-dependent functions.
The following private IOCTLs are supported:
VIDIOC_OMAP3ISP_CCDC_CFG
VIDIOC_OMAP3ISP_PRV_CFG
VIDIOC_OMAP3ISP_AEWB_CFG
VIDIOC_OMAP3ISP_HIST_CFG
VIDIOC_OMAP3ISP_AF_CFG
VIDIOC_OMAP3ISP_STAT_REQ
VIDIOC_OMAP3ISP_STAT_EN
The parameter structures used by these ioctls are described in
include/linux/omap3isp.h. The detailed functions of the ISP itself related to
a given ISP block is described in the Technical Reference Manuals (TRMs) ---
see the end of the document for those.
While it is possible to use the ISP driver without any use of these private
IOCTLs it is not possible to obtain optimal image quality this way. The AEWB,
AF and histogram modules cannot be used without configuring them using the
appropriate private IOCTLs.
CCDC and preview block IOCTLs
=============================
The VIDIOC_OMAP3ISP_CCDC_CFG and VIDIOC_OMAP3ISP_PRV_CFG IOCTLs are used to
configure, enable and disable functions in the CCDC and preview blocks,
respectively. Both IOCTLs control several functions in the blocks they
control. VIDIOC_OMAP3ISP_CCDC_CFG IOCTL accepts a pointer to struct
omap3isp_ccdc_update_config as its argument. Similarly VIDIOC_OMAP3ISP_PRV_CFG
accepts a pointer to struct omap3isp_prev_update_config. The definition of
both structures is available in [1].
The update field in the structures tells whether to update the configuration
for the specific function and the flag tells whether to enable or disable the
function.
The update and flag bit masks accept the following values. Each separate
functions in the CCDC and preview blocks is associated with a flag (either
disable or enable; part of the flag field in the structure) and a pointer to
configuration data for the function.
Valid values for the update and flag fields are listed here for
VIDIOC_OMAP3ISP_CCDC_CFG. Values may be or'ed to configure more than one
function in the same IOCTL call.
OMAP3ISP_CCDC_ALAW
OMAP3ISP_CCDC_LPF
OMAP3ISP_CCDC_BLCLAMP
OMAP3ISP_CCDC_BCOMP
OMAP3ISP_CCDC_FPC
OMAP3ISP_CCDC_CULL
OMAP3ISP_CCDC_CONFIG_LSC
OMAP3ISP_CCDC_TBL_LSC
The corresponding values for the VIDIOC_OMAP3ISP_PRV_CFG are here:
OMAP3ISP_PREV_LUMAENH
OMAP3ISP_PREV_INVALAW
OMAP3ISP_PREV_HRZ_MED
OMAP3ISP_PREV_CFA

Statistic blocks IOCTLs
=======================
The statistics subdevs do offer more dynamic configuration options than the
other subdevs. They can be enabled, disable and reconfigured when the pipeline
is in streaming state.
The statistics blocks always get the input image data from the CCDC (as the
histogram memory read isn't implemented). The statistics are dequeueable by
the user from the statistics subdev nodes using private IOCTLs.
The private IOCTLs offered by the AEWB, AF and histogram subdevs are heavily
reflected by the register level interface offered by the ISP hardware. There
are aspects that are purely related to the driver implementation and these are
discussed next.
VIDIOC_OMAP3ISP_STAT_EN
-----------------------
This private IOCTL enables/disables a statistic module. If this request is
done before streaming, it will take effect as soon as the pipeline starts to
stream. If the pipeline is already streaming, it will take effect as soon as
the CCDC becomes idle.
VIDIOC_OMAP3ISP_AEWB_CFG, VIDIOC_OMAP3ISP_HIST_CFG and VIDIOC_OMAP3ISP_AF_CFG
-----------------------------------------------------------------------------
Those IOCTLs are used to configure the modules. They require user applications
to have an in-depth knowledge of the hardware. Most of the fields explanation
can be found on OMAP's TRMs. The two following fields common to all the above
configure private IOCTLs require explanation for better understanding as they
are not part of the TRM.
omap3isp_[h3a_af/h3a_aewb/hist]_config.buf_size:
The modules handle their buffers internally. The necessary buffer size for the
module's data output depends on the requested configuration. Although the
driver supports reconfiguration while streaming, it does not support a
reconfiguration which requires bigger buffer size than what is already
internally allocated if the module is enabled. It will return -EBUSY on this
case. In order to avoid such condition, either disable/reconfigure/enable the
module or request the necessary buffer size during the first configuration
while the module is disabled.
The internal buffer size allocation considers the requested configuration's
minimum buffer size and the value set on buf_size field. If buf_size field is
out of [minimum, maximum] buffer size range, it's clamped to fit in there.
The driver then selects the biggest value. The corrected buf_size value is
written back to user application.
omap3isp_[h3a_af/h3a_aewb/hist]_config.config_counter:
As the configuration doesn't take effect synchronously to the request, the
driver must provide a way to track this information to provide more accurate
data. After a configuration is requested, the config_counter returned to user
space application will be an unique value associated to that request. When
user application receives an event for buffer availability or when a new
buffer is requested, this config_counter is used to match a buffer data and a
configuration.
VIDIOC_OMAP3ISP_STAT_REQ
------------------------
Send to user space the oldest data available in the internal buffer queue and
discards such buffer afterwards. The field omap3isp_stat_data.frame_number
matches with the video buffer's field_count.

safe to unregister v4l2_device. For this purpose v4l2_device has refcounting
support. The refcount is increased whenever video_register_device is called and
it is decreased whenever that device node is released. When the refcount reaches
zero, then the v4l2_device release() callback is called. You can do your final
cleanup there.

V4L2 sub-device userspace API
-----------------------------
Beside exposing a kernel API through the v4l2_subdev_ops structure, V4L2
sub-devices can also be controlled directly by userspace applications.
Device nodes named v4l-subdevX can be created in /dev to access sub-devices
directly. If a sub-device supports direct userspace configuration it must set
the V4L2_SUBDEV_FL_HAS_DEVNODE flag before being registered.
After registering sub-devices, the v4l2_device driver can create device nodes
for all registered sub-devices marked with V4L2_SUBDEV_FL_HAS_DEVNODE by calling
v4l2_device_register_subdev_nodes(). Those device nodes will be automatically
removed when sub-devices are unregistered.
The device node handles a subset of the V4L2 API.

since it is also used to implement priority handling (VIDIOC_G/S_PRIORITY)

The users of v4l2_fh (in the V4L2 framework, not the driver) know
whether a driver uses v4l2_fh as its file->private_data pointer by
testing the V4L2_FL_USES_V4L2_FH bit in video_device->flags.
Useful functions:
- v4l2_fh_init()
Initialise the file handle. This *MUST* be performed in the driver's
v4l2_file_operations->open() handler.
- v4l2_fh_add()
Add a v4l2_fh to video_device file handle list. May be called after
initialising the file handle.
- v4l2_fh_del()
Unassociate the file handle from video_device(). The file handle
exit function may now be called.

memory can be freed.
testing the V4L2_FL_USES_V4L2_FH bit in video_device->flags. This bit is
set whenever v4l2_fh_init() is called.
struct v4l2_fh is allocated as a part of the driver's own file handle

structure by using the container_of macro. Example:
structure and file->private_data is set to it in the driver's open
function by the driver.
In many cases the struct v4l2_fh will be embedded in a larger structure.
In that case you should call v4l2_fh_init+v4l2_fh_add in open() and
v4l2_fh_del+v4l2_fh_exit in release().

Below is a short description of the v4l2_fh functions used:
int v4l2_fh_init(struct v4l2_fh *fh, struct video_device *vdev)
Initialise the file handle. This *MUST* be performed in the driver's
v4l2_file_operations->open() handler.
void v4l2_fh_add(struct v4l2_fh *fh)
Add a v4l2_fh to video_device file handle list. Must be called once the
file handle is completely initialized.
void v4l2_fh_del(struct v4l2_fh *fh)
Unassociate the file handle from video_device(). The file handle
exit function may now be called.
void v4l2_fh_exit(struct v4l2_fh *fh)
Uninitialise the file handle. After uninitialisation the v4l2_fh
memory can be freed.
If struct v4l2_fh is not embedded, then you can use these helper functions:
int v4l2_fh_open(struct file *filp)
This allocates a struct v4l2_fh, initializes it and adds it to the struct
video_device associated with the file struct.
int v4l2_fh_release(struct file *filp)
This deletes it from the struct video_device associated with the file
struct, uninitialised the v4l2_fh and frees it.
These two functions can be plugged into the v4l2_file_operation's open() and
release() ops.
Several drivers need to do something when the first file handle is opened and
when the last file handle closes. Two helper functions were added to check
whether the v4l2_fh struct is the only open filehandle of the associated
device node:
int v4l2_fh_is_singular(struct v4l2_fh *fh)
Returns 1 if the file handle is the only open file handle, else 0.
int v4l2_fh_is_singular_file(struct file *filp)
Same, but it calls v4l2_fh_is_singular with filp->private_data.
