Jacopo Mondi 93a33e7a0f mali-c55: Plumb the IPA module in
Plumb the Pipeline-IPA loop in.

Load the IPA module at camera creation time and create the loop between
the pipeline and the IPA.

When a new Request is queued the IPA is asked to prepare the parameters
buffer, once ready it notifies the pipeline which queues the parameters
to the ISP along with a buffer for statistics and frames,

Once statistics are ready they get passed to the IPA which upates its
settings for the next frame.

Driveby fix an error message in the Pipeline Handler's ::freeBuffers()
function which reported a problem with the wrong video device in an
error path.

Daniel Scally 10ccab9db9 libcamera: mali-c55: Acquire and plumb in 3a params and stats
Acquire the mali-c55 3a stats and parameters video devices during

For this commit we simply allocate and release buffers for the
statistics and parameters. Statistics buffers are queue and dequeued
from the stats video device but their contents are for now untouched.

Stefan Klug 62959e1f89 pipeline: rkisp1: Limit sensor size to max resolution
In RkISPPath::validate() the sensor sizes are correctly filtered to the
ones supported by the ISP. But later in RkISPPipeline::configure() the
configured stream size is passed to sensor->getFormat() and the
CameraSensor class chooses the best sensor format for the requested
stream size. This can result in a sensor format that is too big for the
ISP. Fix that by supplying the maximum resolution supported by the ISP
to setFormat().

Stefan Klug db9b6f8e23 pipeline: rkisp1: Keep aspect ratio on imx8mp
In the current code, the input stage of the image resizer is used to
apply a crop to keep the aspect ratio in cases where the requested
output aspect ratio differs from the one of the selected sensor mode. On
the imx8mp the resizer hardware is not capable of cropping (for
reference see also rkisp1-resizer.c:rkisp1_rsz_set_sink_crop() in the
linux kernel v6.10).

Therefore apply the necessary cropping on the output of the ISP (on the
image stabilization block). The cropping code on the image resizer
doesn't need modifications as the requested crop gets ignored by the
kernel.

While at it, remove a todo comment that is no longer needed.

Daniel Scally 6925d043f8 libcamera: mali-c55: Correct input/output format representation
At present we configure raw streams by looping through the pixel
formats we support and finding one with an associated media bus
format code that the sensor can produce. In the new representation
of raw data from the kernel driver this will not work - the sensor
could produce 8, 10, 12, 14 or 16 bit data and the ISP will force
it to RAW16, which is the only actually supported output.

To fix the issue move to simply finding a pixel format with a bayer
order that matches that of the media bus format produced by the
sensor. If the sensor can produce multiple formats with the same
bayer order use the one with the largest bitdepth.

Finally, remove the claim to support RAW formats of less than 16 bits.

Instead of re-applying the sensor format to the CSI-2 receiver source
pad (which is now an invalid operation) read from there the format
propagated by the driver internally and further propagate it to the ISP

Jacopo Mondi 8fceb6ab1d libcamera: Rationalize IPA and handlers names
The names used by the IPA interface and the names used for buffer
completions handlers in libcamera clash in the use of the term "buffer".

For example video device buffer completion handler is called
"bufferReady" and the IPA event to ask the IPA to compute parameters are
called "fillParamsBuffers". This makes it hard to recognize which
function handles video device completion signals and which ones handle
the IPA interface events.

Rationalize the naming scheme in the IPA interface function and events
and the signal handlers in the pipelines,  according to the
following table. Remove the name "buffer" from the IPA interface events
and events handler and reserve it for the buffer completion handlers.
Rename the IPA interface events and function to use the 'params' and
'stats' names as well.

IPA Interface:

- fillParamsBuffer -> computeParams   [FUNCTION]
- processStatsBuffer -> processStats  [FUNCTION]
- paramFilled -> paramsComputed       [EVENT]

Pipeline handler:

- bufferReady -> videoBufferReady     [BUFFER HANDLER]
- paramReady -> paramBufferReady      [BUFFER HANDLER]
- statReady -> statBufferReady        [BUFFER HANDLER]
- paramFilled -> paramsComputed       [IPA EVENT HANDLER]

SimplePipelineHandler::kNumInternalBuffers (the number of buffers
allocated in V4L2) was equal to the number of buffers exported from
software ISP.  But when the number of the exported buffers was increased
by one in commit abe2ec64f9, the assertion
error started pop up in some environments.  Increasing the number of the
buffers much more, e.g. to 9, makes the problem very reproducible.

Each pipeline uses its own mechanism to track the requests to clean up
and it can't be excluded that similar omissions are present in other
places.  But there is no obvious way to make a common cleanup for all
the pipelines (except for doing it instead of raising the assertion
error, which is probably undesirable, in order not to hide incomplete
pipeline specific cleanups).

Milan Zamazal 2cc52d6835 libcamera: simple: Track requests in conversionQueue_
Simple pipeline retrieves the requests to complete from the
conversionQueue_.  This patch stores the requests in conversionQueue_
explicitly.  This explicit tracking is supposed to be preferred to
implicit retrieval and it simplifies the completion code a bit here and
in the followup patch that adds request cleanup on stop.

The change as implemented assumes that all the buffers in each of the
conversionQueue_ elements point to the same request, the one specified.

Jacopo Mondi e1d45a17f7 libcamera: rkisp1: Create main buffer pool out of if(!isRaw)
The "useDewarper_" class variable is set to true during configure
only if the configuration is !isRaw.

The main path buffer pool creation can thus be moved out of the
if (!isRaw) block at allocateBuffers() time.

Cosmetic change that will make it easier to create a buffer pool
for the main and self paths unconditionally in future.

Naushir Patuck 58598f4dde pipeline: rpi: Handler controls::rpi::ScalerCrops
Handle multiple scaler crops being set through the rpi::ScalerCrops
control. We now populate the cropParams_ map in the loop where we handle
the output stream configuration items. The key of this map is the index
of the stream configuration structure set by the application. This will
also be the same index used to specify the crop rectangles through the
ScalerCrops control.

CameraData::applyScalerCrop() has been adapted to look at either
controls::ScalerCrop or controls::rpi::ScalerCrops. The latter takes
priority over the former. If only controls::ScalerCrop is provided, the
pipeline handler will apply the same scaler crop to all output streams.

Finally return all crops through the same ScalerCrops control via
request metadata. The first configure stream's crop rectangle is also
returned via the ScalerCrop control in the request metadata.

Add a ispIndex field to CropParams that is used to track
which ISP output (0/1) will be used for a given stream during
configuration.

Tracking this information is required for an upcoming change where crop
rectangles can be specified for each configured stream. Currently, the
value is fixed to 0.

Do not cache the scalerCrop_ parameter. The cached value is used to

Plumb the dw100 dewarper as a V4L2M2M converter in the rkisp1 pipeline
handler. If the dewarper is found, it is instantiated and buffers are
exported from it, instead of RkISP1Path. Internal buffers are allocated
for the RkISP1Path in case where dewarper is going to be used.

The RKISP1 pipeline handler now supports scaler crop control through
the converter. Register the ScalerCrop control for the cameras created
in the RKISP1 pipeline handler.

Umang Jain 485f92ac06 libcamera: rkisp1: Prepare for additional camera controls
Currently the rkisp1 pipeline handler only registers controls that are
related to the IPA. This patch prepares the rkisp1 pipeline-handler to
register camera controls which are not related to the IPA.

Hence, introduce an additional ControlInfoMap for IPA controls. These
controls will be merged together with the controls in the pipeline
handler (introduced subsequently) as part of updateControls() and
together will be registered during the registration of the camera.
This is similar to what IPU3 pipeline handler handles its controls.
