Add a vendor control rpi::ScalerCrops that is analogous to the current core::ScalerCrop, but can apply a different crop to each configured stream. This control takes a span of Rectangle structures - the order of rectangles must match the order of streams configured by the application. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
Do not cache the scalerCrop_ parameter. The cached value is used to update the request metadata, but since this is not an expensive operation (and can only occur once per frame), caching it is of limited value. This will simplify logic in a future commit where we can specify a crop per-output stream. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
…op() This will be required when we program separate crop values to each ISP output in a future commit. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
In preparation for assigning separate crop windows for each stream, add a new CropParams structure that stores the existing ispCrop_ and ispMinCropSize_ as fields. Use a new std::map to store a CropParams structure where the map key is the index of the stream configuration in the CameraConfiguration vector. At preset, only a single CropParams structure will be set at key == 0 to preserve the existing crop handling logic. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
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. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
At this point, the index is unused, but will be in a future commit where we can set different crops on each ISP output. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
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 former takes priority over the latter, and if present, 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. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
sensorInfo_ currently gets populated in configureIPA(), but is possibly referenced in platformConfigure() which is called first. Fix this by populating sensorInfo_ straight after configuring the sensor in configure(), ensuring the fields are valid in the call to platformConfigure().

Ensure we index the CameraConfiguration incrementally when setting up the raw and output streams. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
Add a new subpoject wrap file for the libpisp library located at https://github.com/raspberrypi/libpisp The libpisp library is used to configure the Raspberry Pi 5 Frontend and Backend ISP components.

Add the Raspberry Pi 5 ISP (PiSP) pipeline handler to libcamera. To include this pipeline handler in the build, set the following meson option: meson configure -Dpipelines=rpi/pisp Signed-off-by: Naushir Patuck <naush@raspberrypi.com> Reviewed-by: David Plowman <david.plowman@raspberrypi.com>

The IMX708 sensor driver advertises its module variants (narrow/wide angle lens, IR block/pass) by modifying the media entity name string. So add duplicate entries for each variant.

Look for the RAW mandatory stream flag in the pipeline handler config file. If this flag is set, it guarantees that the application will provide buffers for Unicam Image, so override the minUnicamBuffers and minTotalUnicamBuffers config parameters in the following way: - If startup drop frames are required, allocate at least 1 internal buffer. - If no startup drop frames are required, do not allocate any internal buffers. Look for the Output 0 mandatory stream flag in in the pipeline handler config file. If this flag is set, it guarantees that the application will provide buffers for the ISP, do not allocate any internal buffers for the device. Add a new rpi_apps.yaml pipeline handler config file that enables both these flags. To use the file, set the following env variable for a custom build: export LIBCAMERA_RPI_CONFIG_FILE=/usr/local/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml or for a packaged install: export LIBCAMERA_RPI_CONFIG_FILE=/usr/share/libcamera/pipeline/rpi/vc4/rpi_apps.yaml Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
… buffers V4L2 only allows upto VIDEO_MAX_FRAME frames to be queued at a time, so if we reach this limit, store the framebuffers in a pending queue, and try to enqueue once a buffer has been dequeued. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
Use an r-value reference in set() and setLocked(), allowing more efficient metadata handling with std::forward and std::move if needed. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
These function erases a key/value pair from the metadata object. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
This property (cfeDataBufferStrided) indicates if the CSI-2 hardware writes to the embedded/metadata buffer directly, or if it treats the buffer like an image buffer and strides the metadata lines. Unicam write this buffer strided, while the PiSP Frontend writes to it directly. This information will be relevant to data parsers in the helpers where the data is structured in lines.

Add the follwing RPi vendor controls to handle Convolutional Neural Network processing: CnnOutputTensor CnnOutputTensorInfo CnnEnableInputTensor CnnInputTensor CnnInputTensorInfo CnnKpiInfo These controls will be used to support the new Raspberry Pi AI Camera, using an IMX500 sensor with on-board neural network processing. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
Add code to handle the new CNN vendor controls in the Raspberry Pi IPA. The value of CnnInputTensorInfo is cached as it is the only stateful input control. All other controls are output controls, and the values are copied into directly from the rpiMetadata object if present. The camera helpers populate the rpiMetadata object if the sensor supports on-board CNN processing, such as the IMX500. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
Add a CamHelper::setHwConfig() helper used by the IPA to set the hardware configuartion in use by the pipeline. This will be needed by the IMX500 camera helper in a future commit to determine if the metadata buffer is strided. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>
Add a Sony IMX500 camera helper to the IPA. This also includes support for the on-chip CNN hardware accelerator and parsing of the neural network data stream returned in the metadata buffer. Add tuning files for both VC4 and PiSP platforms. Signed-off-by: Naushir Patuck <naush@raspberrypi.com>

Kieran sent the vc4 and cam_helper upstream - any chance of a review there? https://lists.libcamera.org/pipermail/libcamera-devel/2024-October/045749.html |
|
Should I already see it in next or am I getting something wrong? |
|
It will come to next/main when I rebase from upstream libcamera in a few days (hopefully). |
