2023-06-17libcamera: camera_manager: Move {add,remove}Camera to internalKieran Bingham
The CameraManager exposes addCamera and removeCamera as public API calls, while they should never be called from an application. These calls are only expected to be used by PipelineHandlers to update the CameraManager that a new Camera has been created and allow the Camera Manager to expose it to applications. Remove the public calls and update the private implementations such that they can be used directly by the PipelineHandler through the internal CameraManager::Private provided by the Extensible class.

2023-06-17libcamera: camera_manager: Move private implementation to internalKieran Bingham
The CameraManager makes use of the Extensible pattern to provide an internal private implementation that is not exposed in the public API. Move the Private declaration to an internal header to make it available from other internal components in preperation for reducing the surface area of the public interface of the CameraManager.

Remove the verbose #ifndef/#define/#endif pattern for maintaining header idempotency, and replace it with a simple #pragma once.

2023-06-06libcamera: rkisp1: Fix enumeration of RAW formatsJacopo Mondi
The current implementation enumerates a single RAW format (the sensor's resolution) and does that regardless of what role the CameraConfiguration has been generated for. Fix this by: - Enumerate RAW StreamFormats only when the requested role is StreamRole::Raw - Add all the sensor's provided resolutions that fit the video device output maximum size Before this patch, a single RAW size was enumerated in stream formats * Pixelformat: SRGGB10 (4208x3120)-(4208x3120)/(+1,+1) - 4208x3120 With this patch applied all sensor's supported resolutions are enumerated but only when the stream role RAW is explicitly requested * Pixelformat: SRGGB10 (1048x780)-(4208x3120)/(+0,+0) - 1048x780 - 2104x1560 - 4032x3024 - 4208x3120 Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>
2023-06-06libcamera: rkisp1: Assign sizes to rolesJacopo Mondi
Currently each RkISP1 path (main and self) generate a configuration by bounding the sensor's resolution to their respective maximum output aspect ratio and size. Size maxResolution = maxResolution_.boundedToAspectRatio(resolution) .boundedTo(resolution); In the case of self path, whose maximum size is 1920x1920, the generated configuration could get assigned unusual sizes, as the result of the above operation. As an example, with the imx258 sensor whose resolution is 4208x3118, the resulting size for the Viewfinder use case is an unusual 1920x1423. Fix this by assigning to each role a desired output size: - Use the sensor's resolution for StillCapture and Raw - Use 1080p for Viewfinder and VideoRecording Signed-off-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Paul Elder <paul.elder@ideasonboard.com> Reviewed-by: Kieran Bingham <kieran.bingham@ideasonboard.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2023-06-06libcamera: rkisp1: Generate config using main pathJacopo Mondi
The generateConfiguration() implementation in the Rockchip RkISP1 pipeline handler uses by default the self path (if available) for the Viewfinder and VideoRecording StreamRoles. The validate() implementation, at the contrary, prefers using the main path, when available, for all streams. As the self-path is limited in output resolution to 1920x1920, generating a configuration using the self path limits the maximum stream size to 1920x1920, while higher resolutions can be obtained by using the main path. Align the generateConfiguration() implementation to the validate() one by using the main path by default if available.

2023-05-31py: Move to mainline pybind11 versionTomi Valkeinen
We are using pybind11 'smart_holder' branch to solve the Camera destructor issue (see the comment in this patch, or the commit that originally added Python bindings support). As it would be very nice to use the mainline pybind11 (which is packaged in distributions), this patch adds a workaround allowing us to move to the mainline pybind11 version. The workaround is simply creating a custom holder class (PyCameraSmartPtr), used only for the Camera, which wraps around the shared_ptr. This makes the compiler happy. Moving to mainline pybind11 is achieved with: - Change the pybind11 wrap to point to the mainline pybdind11 version - Tell pybind11 to always use shared_ptr<> as the holder for PyCameraManager, as we use the singleton pattern for the PyCameraManager, and using shared_ptr<> to manage it is a requirement - Tell pybind11 to always use PyCameraSmartPtr<> as the holder for Camera - Change the meson.build file to use a system-installed pybind11 Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

2023-05-04ipa: raspberrypi: Introduce IpaBase classNaushir Patuck
Create a new IpaBase class that handles general purpose housekeeping duties for the Raspberry Pi IPA. The implementation of the new class is essentially pulled from the existing ipa/rpi/vc4/raspberrypi.cpp file with a minimal amount of refactoring. Create a derived IpaVc4 class from IpaBase that handles the VC4 pipeline specific tasks of the IPA. Again, code for this class implementation is taken from the existing ipa/rpi/vc4/raspberrypi.cpp with a minimal amount of refactoring. The goal of this change is to allow third parties to implement their own IPA running on the Raspberry Pi without duplicating all of the IPA housekeeping tasks.

2023-05-04pipeline: ipa: raspberrypi: Restructure the IPA mojom interfaceNaushir Patuck
Restructure the IPA mojom interface to be more consistent in the use of the API. Function parameters are now grouped into *Params structures and results are now returned in *Results structures. The following pipeline -> IPA interfaces have been removed: signalQueueRequest(libcamera.ControlList controls); signalIspPrepare(ISPConfig data); signalStatReady(uint32 bufferId, uint32 ipaContext); and replaced with: prepareIsp(PrepareParams params); processStats(ProcessParams params); signalQueueRequest() is now encompassed within prepareIsp(). The following IPA -> pipeline interfaces have been removed: runIsp(uint32 bufferId); embeddedComplete(uint32 bufferId); statsMetadataComplete(uint32 bufferId, libcamera.ControlList controls); and replaced with the following async calls: prepareIspComplete(BufferIds buffers); processStatsComplete(BufferIds buffers); metadataReady(libcamera.ControlList metadata); Signed-off-by: Naushir Patuck <naush@raspberrypi.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2023-05-04pipeline: raspberrypi: rpi_stream: Set invalid buffer to id == 0Naushir Patuck
At present, the RPiStream buffer ids == -1 indicates an invalid value. As a simplification, use id == 0 to indicate an invalid value. This allows for better code readability. As a consequence of this, use unsigned int for the buffer id values.

2023-05-04pipeline: ipa: raspberrypi: Refactor and move the Raspberry Pi codeNaushir Patuck
Split the Raspberry Pi pipeline handler and IPA source code into common and VC4/BCM2835 specific file structures. For the pipeline handler, the common code files now live in src/libcamera/pipeline/rpi/common/ and the VC4-specific files in src/libcamera/pipeline/rpi/vc4/. For the IPA, the common code files now live in src/ipa/rpi/{cam_helper,controller}/ and the vc4 specific files in src/ipa/rpi/vc4/. With this change, the camera tuning files are now installed under share/libcamera/ipa/rpi/vc4/. To build the pipeline and IPA, the meson configuration options have now changed from "raspberrypi" to "rpi/vc4": meson setup build -Dipas=rpi/vc4 -Dpipelines=rpi/vc4 Signed-off-by: Naushir Patuck <naush@raspberrypi.com> Reviewed-by: Jacopo Mondi <jacopo.mondi@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

The current pipeline handler build files require a flat directory struture for each pipeline handler. Modify the build files to remove this restriction and allow a directory structure such as: src/libcamera/pipeline/ |- raspberrypi |- common |- vc4 |- rkisp1 |- ipu3 where each subdir (e.g. raspberrypi/common, raspberrypi/vc4) has its own meson.build file. Such a directory structure will be introduced for the Raspberry Pi pipeline handler in a future commit.
