2022-06-29ipa: libipa: algorithm: Add an algorithm registration mechanismLaurent Pinchart
In order to allow dynamic instantiation of algorithms based on tuning data files, add a mechanism to register algorithms with the IPA module. The implementation relies on an AlgorithmFactory class and a registration macro, similar to the pipeline handler registration mechanism. The main difference is that the algorithm registration and instantiation are implemented in the Module class instead of the AlgorithmFactory class, making the factory an internal implementation detail.

2022-06-29ipa: libipa: Introduce a Module class templateLaurent Pinchart
libipa defines an abstract Algorithm class template that is specialized by IPA modules. IPA modules then instantiate and manage algorithms internally, without help from libipa. With ongoing work on tuning data support for the RkISP1, and future similar work for the IPU3, more code duplication for algorithms management is expected. To address this and share code between multiple IPA modules, introduce a new Module class template that will define and manage top-level concepts for the IPA module. The Module class template needs to be specialized with the same types as the Algorithm class. To avoid manual specialization of both classes, store the types in the Module class, and replace the template arguments of the Algorithm class with a single Module argument from which the other types are retrieved.

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().

Currently the pipeline handler advertises controls handled by the IPA from a static ControlInfoMap defined in the raspberrypi.h header. This change removes this header file, and instead the IPA returns the ControlInfoMap to the pipeline handler from the ipa::init() function. This is done to allow the IPA to adjust the limits of the controls based on the sensor mode in a subsequent change.
