2022-07-14ipa: algorithms: af: Do not inherit from Algorithmjmondi/rockpi/af/imx519Jacopo Mondi
The AfAlgorithm class defines the pure virtual interface for the Auto-focus algorithms and it is not meant to be instantiated. In the same way the AfHillClimbing class cannot be directly instantiated as it contains two pure virtual members. The platform-specific implementation is instead the class that will be registered to the AlgorithmFactory, and it's the only one that needs to inherit from Algorithm for this reason. Remove the Module template argument from the class hierarchy and have the platform specific class inherit from Algorithm. Signed-off-by: Jacopo Mondi <jacopo@jmondi.org>

2022-07-04gstreamer: Fix race conditions in task pause/resumeLaurent Pinchart
The task run function races with two other threads that want to resume the task: the requestCompleted() handler and the buffer-notify signal handler. If the former queues completed requests or the latter queues back buffers to the pool, and then resume the task, after the task run handler checks the queues but before it attemps to pause the task, then the task may be paused without noticing that more work is available. The most immediate way to fix this is to take the stream_lock in the requestCompleted() and buffer-notify signal handlers, or cover the whole task run handler with the GstLibcameraSrcState lock. This could cause long delays in the requestCompleted() handler, so that's not a good option. Instead, pause the task unconditionally at the beginning of its run function, and track while processing buffers and requests if the task needs to be resumed. It may also get resumed externally by the buffer-notify signal handler or the request completion handler, which are guaranteed not to race due to the lock taken by the gst_task_pause() and gst_task_resume() functions.

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.

Before the first call to Camera::configure(), this ControlInfoMap provides some reasonable default limits for ExposureTime, AnalogueGain, and FrameDurationLimits.
