[PATCH v12 00/86] Generic line based metadata support, internal pads

Hi folks,

Here are a few patches to add support generic, line based metadata as well
as internal pads, sub-device configuration models (including the common
raw sensor model) and a streaming control helper for MC-enabled drivers.
The amount of code and documentation is in this version is no longer small
but it still requires some explaining.

Metadata mbus codes and formats have existed for some time in V4L2. They
however have been only used by drivers that produce the data itself and
effectively this metadata has always been statistics of some sort (at
least when it comes to ISPs). What is different here is that we intend to
add support for metadata originating from camera sensors.

Camera sensors produce different kinds of metadata, embedded data (usually
register address--value pairs used to capture the frame, in a more or less
sensor specific format), histograms (in a very sensor specific format),
dark pixels etc. The number of these formats is probably going to be about
as large as image data formats if not larger, as the image data formats
are much better standardised but a smaller subset of them will be
supported by V4L2, at least initially but possibly much more in the long
run.

Having this many device specific formats would be a major problem for all
the other drivers along that pipeline (not to mention the users of those
drivers), including bridge (e.g. CSI-2 to parallel) but especially CSI-2
receiver drivers that have DMA: the poor driver developer would not only
need to know camera sensor specific formats but to choose the specific
packing of that format suitable for the DMA used by the hardware. It is
unlikely many of these would ever get tested while being present on the
driver API. Also adding new sensors with new embedded data formats would
involve updating all bridge and CSI-2 receiver drivers. I don't expect
this to be a workable approach.

Instead what I'm proposing is to use controls to convey the colour pattern
and metadata layout. Generic mbus codes convey the width of the data
transferred on serial buses (for now, corresponding parallel formats may
be added when needed) but the control is only relevant on the UAPI, not
between drivers. This approach unsnarls the layout of the data and its
colour components, defining what data there is (specific mbus code) and
how that is transported and packed (generic mbus codes and V4L2 formats)
separately.

The user space would be required to "know" the path of that data from the
sensor's internal pad to the V4L2 video node. I do not see this as these
devices require at least some knowledge of the pipeline, i.e. hardware at
hand. Separating what the data means and how it is packed may even be
beneficial: it allows separating code that interprets the data (sensor
internal mbus code) from the code that accesses it (packing).

These formats are in practice line based, meaning that there may be
padding at the end of the line, depending on the bus as well as the DMA.
If non-line based formats are needed, it is always possible to set the
"height" field to 1.

Internal sink pads behave mostly like regular sink pads, but they describe
a flow of data that originates from a sub-device instead of arriving to a
sub-device. The SUBDEV_S_ROUTING IOCTLs are used to enable and disable
routes from internal sink pads to sub-device's source pads. The subdev
format IOCTLs are usable, too, so one can find which subdev format is
available on given internal sink pad.

I've tested the patches using the IPU6 / ov2740 pair of drivers as well as
Unicam / imx219.

Questions and comments are most welcome.

Preliminary media-ctl and yavta patches can be found here:

<URL:https://git.retiisi.eu/?p=~sailus/yavta.git;a=shortlog;h=refs/heads/metadata>
<URL:https://git.retiisi.eu/?p=~sailus/v4l-utils.git;a=shortlog;h=refs/heads/metadata>

I have used IMX219 as an example on routing in a sensor driver in this
version.

The patches are on my metadata branch
<URL:https://git.linuxtv.org/sailus/media_tree.git/log/>.

These patches are on top of my metadata preparation set
<20260408153939.969381-1-sakari.ailus@linux.intel.com>, all of these can
be found in the GitWeb URL above.

The documentation build output can be found here:
<URL:https://www.retiisi.eu/~sailus/v4l2/tmp/common-raw/>.

since v11:

- Add a note (patch "media: Documentation: Add a note on Bayer raw mbus
codes") to document the use of new generic raw formats

- Link to the LINK_FREQ control from the tx-rx driver documentation.

- Refer to V4L2 fwnode endpoint parsing functions in tx-rx driver
documentation.

- Rename V4L2_CID_COLOR_PATTERN as V4L2_CID_CFA_PATTERN. This matches
better with the established use of the terms (CFA in particular).

- Improve and fix references in new camera sensor driver documentation.

- Improve and fix language regarding embedded data in camera sensor driver
documentation.

- Improve language in routing documentation in dev-subdev.rst.

- Document the IMMUTABLE route flag in routing documentation.

- Add a note in routing documentation that a sub-device may have either
user-created or static routes.

- Also use IMMUTABLE and STATIC flags in internal pads example.

- Elaborate image and metadata stream dependencies in imx219
documentation.

- Don't mention selections in sub-device configuration documentation for
internal pads.

- The source format of the camera sensor is configured using the source
pad; document this in the Common raw sensor model.

- Move binning factors from camera controls class to image source class
where they belong.

- Improve description of colour filter array patterns.

- Add that CFA_PATTERN_FLIP is a read-only control.

- Add references to metadata layouts into the metadata layout control.

- Refer to V4L2_METADATA_LAYOUT_OV2740 in ov2740 documentation (not
V4L2_METADATA_LAYOUT_CCS).

- Note that ov2740 embedded data dpc correction threshold uses bits 9--2.

- Postpone adding 16 and higher bpp generic raw formats until we have a
user (split into separate patches later in the set).

- Generic 16- and 24-bit format isn't really CSI-2 packed (but appears to
be big endian) so rename the two accordingly.

- Small but numerous fixes in generic raw image data format documentation.

- Improve documentation of different parts of the pixel array and relation
of that to the UAPI under common raw sensor model documentation.

- Reword documentation of the compose rectangle in common raw sensor
model documentation.

- Add crop bounds rectangle to the common raw sensor model to convey the
bounds of the pixel array. This allows using negative numbers as well.

- Document that the sensor's output format is configured on the source
pad.

- Add references to relevant controls in generic raw format documentation.

- Introduce V4L2_SUBDEV_CLIENT_CAP_COMMON_RAW_SENSOR sub-device capability
bit. This bit is set by the userspace to signal support for the common
raw sensor model and allows supporting common raw sensor model also in
existing drivers.

- Introduce the static route flag to indicate a route is always present.

- Add new struct v4l2_subdev_client_info as argument to certain pad
operations in order to support passing information on client
capabilities to sub-device drivers.

- Added common raw format support to the CCS driver.

- Drop leftover mutex_unlock() in ccs_set_format().

- Fully rely on sub-device state locking in the CCS driver.

- Make METADATA_LAYOUT control read-only.

- Add new controls FRAME_LENGTH_LINES and LINE_LENGTH_PIXELS.

- Don't handle the CFA pattern control in set_ctrl() -- ops is NULL.

- Support the common raw sensor model in imx219:

- Add support for BINNING_FACTORS, FRAME_LENGTH_LINES and
LINE_LENGTH_PIXELS controls.

- Support both Common Raw Sensor Model and old behaviour,
depending on V4L2_SUBDEV_CLIENT_CAP_COMMON_RAW_SENSOR bit. The
internal state is the same in both cases but the view to the
state and UAPI behaviour differs based on that bit.

- Keep track of enabled streams; any started stream starts
streaming on the sensor.

- Enumerate only generic raw mbus code on the internal image
source pad.

- Support set_selection for setting analogue crop area.

- Remove redundant comments in imx219_probe().

- Ipu6 driver changes:

- Lots of cleanups.

- Only start streaming on the upstream sub-device when all queues
in the pipeline have been set streaming.

- Use VALIDATE_LATE link flag for links to video nodes.

- Move streaming control to the CSI-2 driver. Streaming now starts
on the upstream sub-device once all participating video nodes
have been set streaming.

- Support generic raw formats in the unicam driver.

- Document that common raw sensor model requires implementing
FRAME_LENGTH_LINES and LINE_LENGTH_PIXELS controls.

since v10:

- Merge a few patches that aren't strictly related to metadata, mostly
documentation cleanups and improvements.

- Add V4L2_SUBDEV_ROUTE_FL_STATIC, to indicate a route is mutable but
hardware specific so it remains even if disabled. An example of this are
embedded data routes on camera sensors. IMMUTABLE implies STATIC.

- Postpone adding formats higher than 14 bpp and remove reference to
"little endian" for the CSI-2 packed formats. It's not entirely clear
how the data on higher bit depth formats are laid out in memory. The
documentation suggests these are in big endian format but that would be
impractical for CPU processing.

- Add references to controls in flipping documentation in
subdev-formats.rst.

- Add -ENXIO return code for device specific invalid routing configuration
and clarify routing error conditions for -EINVAL.

- Add braces for the case in imx219_enum_mbus_code() to make Clang happy.

- Rebase off of mc-streamon set (to my cleanup branch). The problem of
when to stream on and off still needs to be addressed but I'm looking
into a different, better integrated approach right now.

- Rename generic metadata formats at bit depths 16 and 24 as it seems
these have more generic packing than CSI-2.

since v9:

- Introduce controls for sub-device configuration models (separately
discussed in <20250203085853.1361401-1-sakari.ailus@linux.intel.com>),
with the following changes:

- Fix spelling and improve wording in documentation based on
comments.

- Use US English spelling for V4L2 control names.

- Allow for more than one internal pad for pixel data.

- Introduce (or change a bit) generic mbus codes for raw pixel
data and metadata.

- Introduce generic and CSI-2 specifc V4L2 pixelformats for image
data and metadata. Also 16- and 24-bit formats are generic, not
specific to CSI-2.

- Introduce new controls to convey metadata layout on bus and by
extension, in memory, instead of relying on separate metadata
mbus codes, aligning with pixel data.

- Use generic metadata codes in the example.

- Include imx219 embedded data support patches from Laurent, with
modifications.

- Patches to IPU6 ISYS driver needed to support metadata capture. Luma
formats added, too.

- Improved debug prints in v4l2_subdev_{en,dis}able_streams().

- Added a patch to make media_entity_to_video_device() NULL-safe.

- Drop _media-glossary-data-unit reference, use :term: to reference it.

- Include a patch to set IPU6 ISYS minimum height to 1.

- Patch 'media: uapi: Document which mbus format fields are valid for
metadata' already merged.

- Patch 'media: uapi: v4l: Add generic 8-bit metadata format definitions'
already merged.

- Patch 'media: v4l: Support line-based metadata capture' already merged.

- Patch 'media: Documentation: Document S_ROUTING behaviour' already merged.

- Patch 'media: v4l: subdev: Add len_routes field to struct
v4l2_subdev_routing' already merged.

since v8:

- Move the patch adding internal pad flag past the routing API reworks, as
well as a few other patches, in order to separate the patches to those
that could still be merged for v6.10 (routing changes) and those that
couldn't (sensor API related). The patch on the edge is "media: uapi:
v4l: subdev: Enable streams API".

- Include Laurent's two patches to address crop API issues wrt. streams.

- Add two patches to prepare for CCS driver rework (media: ccs: Move
ccs_pm_get_init function up and media: ccs: Rename out label of
ccs_start_streaming).

- Address issues in the ov2740 driver patches (as well as the driver
itself), 4 more patches towards the end of the set.

- Improved generic metadata format names, align with other existing
formats.

- Improved ov2740 embedded data documentation.

- Reworked streams and camera sensor documentation based on Laurent's
comments mainly. In particular, the contradictory concept of internal
source pads no longer should exist in the patches.

- Fixed pad numbering in the CCS example.

- Fixed S_ROUTING behaviour when len_routes is too small and when
S_ROUTING isn't implemented by the driver.

- Reorder sections in meta-formats.rst alphabetically.

- Add a note per struct fields that certain struct v4l2_subdev_format are
zero for metadata mbus codes.

- CCS driver patch cleanups.

- CCS driver metadata width fix for space-efficient embedded data at 16
bpp and over.

- Postpone CCS frame descriptor quirk for now.

- Use MIPI_CSI2_DT_USER_DEFINED(0) instead of a numerical value for
compressed data datatype.

since v7:

- Add embedded data support for the ov2740 driver.

- Add three patches on top, to add an IMMUTABLE flag to source streams
when they cannot be disabled.

- Improved documentation of len_routes and num_routes arguments of
[GS]_ROUTING.

- Remove one inclusion of twice-included media/v4l2-fwnode.h in
drivers/media/i2c/ccs/ccs-core.c .

- Add missing forward declaration of ccs_internal_ops in
drivers/media/i2c/ccs/ccs-core.c .

since v6:

- Improve embedded data UAPI documentation on camera sensors.

- Improve wording of stream glossary entry.

- Improve internal pad flag documentation.

- Fix definition of "data unit" and remove an extra "only" in INTERNAL pad
flag description (1st patch).

- Use IMX219 driver in examples consistently.

- Remove the CSI-2 to parallel bridge from the example to simplify the
example.

- Minor rewording of some parts of the routing examples.

- Rebase on unified sub-device state information access functions:
<URL:https://lore.kernel.org/linux-media/20231027095913.1010187-1-sakari.ailus@linux.intel.com/T/#t>

- In CCS driver, do not maintain current active configuration in driver's
device context struct (apart from mbus codes). Rely on sub-device state
locking and clean up the code. (Multiple patches towards the end of the
set.)

- Arrange the CCS patches early in the set towards the end of the set.

- Move the patch enabling streams API to the end of the set.

- Rework IOCTL argument copying condition for [GS]_ROUTING).

- Handle copying back routes in S_ROUTING, do not rely on G_ROUTING
IOCTL implementation.

- Rebase on metadata preparation patchset v6:
<URL:https://lore.kernel.org/linux-media/20231106121805.1266696-1-sakari.ailus@linux.intel.com/T/#t>.

since v5:

- Rebase on new set of preparation patches.

- Switch CCS driver from s_stream to enable_streams/disable_streams. Keep
streaming state information --- the sensor remains in streaming state if
any of the streams is enabled.

- Fix setting mbus code on embedded data in get_frame_desc() op in the CCS
driver.

since v4:

- Add a patch to acquire two sub-device states that may use the same lock.

- Add a patch for CCS driver to remove ccs_get_crop_compose() helper.

- Add a patch for CCS driver moving acquiring and releasing the mutex to
the s_stream callback.

- Add a patch for CCS driver to rely on sub-device state locking using a
single driver-provided lock.

- Fixed calculating minimum number of routes in copying the routes
(thanks, Laurent).

- Moved a label in S_ROUTING handling to make Clang happy (hopefully).

- Fixed setting emb_data_ctrl register for CCS embedded data support.

- Rebase on Laurent's cleanup patches.

- Wrap a few long lines.

- Write in embedded data documentation sensor drivers generally don't
allow configuring it.

since v3:

- Separate preparation patches from this set.

- Add a definition for "Data unit", a pixel that is not image data and use
it instead in format documentation.

- Fix more numbered lists in dev-subdev.rst.

- Remove a redundant definition for V4L2_META_FMT_GENERIC_CSI2_2_24 ---
V4L2_META_FMT_GENERIC_CSI2_12 can be used instead.

- Use "X" instead of "p" to denote padding in format documentation.

- Use IMX219 in examples instead of CCS.

- Document that the generic V4L2 CSI-2 metadata formats use padding
defined in CSI-2 spec and packing defined in CCS spec.

- Add patches to align [GS]_ROUTING behaviour with V4L2. This means mainly
returning configured routes as part of S_ROUTING as well. "len_routes"
field is added to denote the length of the array and having more routes
than fits in the array is no longer an error. Also added more reserved
fields.

- Added trivial support for S_ROUTING (via G_ROUTING implementation) for
use in drivers with static-only routes.

- Added helper functions to obtain mbus format as well as crop and compose
rectangles that are streams-independent.

- Added a patch to define generic CSI-2 long packet types.

- Removed MEDIA_BUS_FMT_IS_META() macro. It didn't seem useful in the end.

- Use a single CCS embedded data format. The bit depth can be selected
using the meta stream on the source pad.

- Fix mbus code numbers (there were holes due to removed redundant
formats).

- Fix generic mbus code documentation (byte was being used instead of
bit).

- Fix spelling of "length".

- Added a patch to remove v4l2_subdev_enable_streams_api that disables
streams API. This should be merged once libcamera support for streams
works nicely.

- Don't use strings in printing frame descriptor flags.

- Warn on string truncation in printing frame descriptor.

since v2:

- Add a better example, with formats.

- Add CCS static data media bus codes.

- Added an example demonstrating the use of internal pads. --- Is the
level of detail enough for the purpose?

- Improved documentation.

- Added a macro to tell whether a format is a metadata format.
(Documentation could be added.)

- A small ReST syntax fix in the same section.

- Drop leftovers of a patch checking for the INTERNAL_SOURCE flag.

since v1:

- Make the new pad flag just "INTERNAL", requiring either SINK or SOURCE
pad flag to accompany it. Removed the union in struct v4l2_subdev_route.

- Add the term "stream" to MC glossary.

- Improved and fixed documentation (according to comments).

- Note these formats are little endian.

- Remove 1X8 from the names of the mbus codes. These formats have generally
8 bits per pixel.

- Fix mbus code numbering (had holes in RFC).

- Add new metadata fields to debug prints.

- Fix a minor documentation build issue.
