2021-05-24ipa: mojom: Move CameraSensorInfo struct exclusively to IPA IPCUmang Jain
CameraSensorInfo structure is designed to pass in camera sensor related information from pipeline-handler to IPA. Since the pipeline-handler and IPA are connected via mojom IPC IPA interface, the interface itself provides a more suitable placement of CameraSensorInfo, instead of camera_sensor.h (which is a libcamera internal header ultimately, at this point). As CameraSensorInfo is already defined in core.mojom, it is just a matter of removing [skipHeader] tag to allow code-generation of CameraSensorInfo. Finally, update header paths to include CameraSensorInfo definition from IPA interfaces instead of "libcamera/internal/camera_sensor.h".

2021-05-11ipa: raspberrypi: Rate-limit the controller algorithmsNaushir Patuck
The controller algorithms currently run on every frame provided to the IPA by the pipeline handler. This may be undesirable for very fast fps operating modes where it could significantly increase the computation cycles (per unit time) without providing any significant changes to the IQ parameters. The added latencies could also cause dropped frames. Pass the FrameBuffer timestamp to the IPA through the controls. This timestamp will be used to rate-limit the controller algorithms to run with a minimum inter-frame time given by a compile time constant, currently set to 16.66ms. On startup, we don't rate-limit the algorithms until after the number of frames required for convergence.

CamHelpers get virtual Prepare() and Process() methods, running just before and just after the ISP, just like Raspberry Pi Algorithms. The Prepare() method is able to parse the register dumps in embedded data buffers, and can be specialised to perform custom processing when necessary.

The tuning was done with an Innomaker STARVIS IMX327LQR module. These have no IR cut filter so there is no proper colour tuning. However, you should obtain reasonable results for most modules using this sensor. Specific tunings for further modules can always be added subsequently.

2021-03-04pipeline: ipa: raspberrypi: Pass exposure/gain values to IPA though controlsNaushir Patuck
When running with sensors that had no embedded data, the pipeline handler would fill a dummy embedded data buffer with gain/exposure values, and pass this buffer to the IPA together with the bayer buffer. The IPA would extract these values for use in the controller algorithms. Rework this logic entirely by having a new RPiCameraData::BayerFrame queue to replace the existing bayer queue. In addition to storing the FrameBuffer pointer, this also stores all the controls tracked by DelayedControls for that frame in a ControlList. This includes include exposure and gain values. On signalling RPi::IPA_EVENT_SIGNAL_ISP_PREPARE IPA event, the pipeline handler now passes this ControlList from the RPiCameraData::BayerFrame queue. The IPA now extracts the gain and exposure values from the ControlList instead of using RPiController::MdParserRPi to parse the embedded data buffer.

2021-02-16ipa: raspberrypi: meson: Add dependency on generated headersPaul Elder
The raspberrypi IPA will depend on the raspberrypi IPA header generated from the mojo definition file. Add the dependency. Simply add all generated headers as a dependency, instead of walking the list of headers, to simplify the implementation. This will have the effect of generating all headers before compiling the IPA, which has no drawbacks.

2021-02-11ipa: raspberrypi: AWB: Fix race condition setting manual gainsDavid Plowman
Applying the manual_r_ and manual_b_ values is entirely removed from the asynchronous thread where their use constituted a race hazard. The main thread now deals with them entirely, involving the following changes. 1. SetManualGains() applies the new values directly to the "sync_results", meaning that Prepare() will jump to the new values immediately (which is a better behaviour). 2. Process() does not restart the asynchronous thread when manual gains are in force. 3. The asynchronous thread might be running when manual gains are set, so we ignore the results produced in this case.
