Update CamHelper::getDelays() to return the sensor HBLANK delay. The HBLANK delay is set to the same value as VBLANK delay for all sensors in the Raspberry Pi IPA.

Previously, ControlList::get<T>() would use default constructed objects to indicate that a ControlList does not have the requested Control. This has several disadvantages: 1) It requires types to be default constructible, 2) it does not differentiate between a default constructed object and an object that happens to have the same state as a default constructed object. std::optional<T> additionally stores the information if the object is valid or not, and therefore is more expressive than a default constructed object.

2022-06-29pipeline: ipa: raspberrypi: Correctly report available control limitsNaushir Patuck
The ipa currently advertises a static ControlInfoMap to specify the available controls and their limits. Fix this limitation by having the IPA populate a new ControlInfoMap with updated limits for ExposureTime, AnalogueGain, and FrameDurationLimits controls based on the current sensor mode. This new ControlInfoMap is then returned back to the pipeline handler and available to the application after a successful Camera::configure() call. Before the first call to Camera::configure(), this ControlInfoMap provides some reasonable default limits for ExposureTime, AnalogueGain, and FrameDurationLimits. However, applications must not rely on these values, but obtain the correct limits after the call to Camera::configure().

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.
