2022-05-18ipa: ipu3: Put IPAFrameContext(s) in a ring bufferUmang Jain
Instead of having one frame context constantly being updated, this patch aims to introduce per-frame IPAFrameContext which are stored in a ring buffer. Whenever a request is queued, a new IPAFrameContext is created and inserted into the ring buffer. The IPAFrameContext structure itself has been slightly extended to store a frame id and a ControlList for incoming frame controls (sent in by the application). The next step would be to read and set these controls whenever the request is actually queued to the hardware. Since now we are working in multiples of IPAFrameContext, the Algorithm::process() will actually take in a IPAFrameContext pointer (as opposed to a nullptr while preparing for this change).

2022-05-18ipa: libipa: Add frame context pointer in process()Umang Jain
Currently we have a single structure of IPAFrameContext but subsequently, we shall have a ring buffer (or similar) container to keep IPAFrameContext structures for each frame. It would be a hassle to query out the frame context required for process() (since they will reside in a ring buffer) by the IPA for each process. Hence, prepare the process() libipa template to accept a particular IPAFrameContext early on. As for this patch, we shall pass in the pointer as nullptr, so that the changes compile and keep working as-is.

2022-05-18ipa: ipu3: Rework IPAFrameContextUmang Jain
Currently, IPAFrameContext consolidates the values computed by the active state of the algorithms, along with the values applied on the sensor. Moving ahead, we want to have a frame context associated with each incoming request (or frame to be captured). This shouldn't necessarily be tied to "active state" of the algorithms hence: - Rename current IPAFrameContext -> IPAActiveState This will now reflect the latest active state of the algorithms and has nothing to do with any frame-related ops/values. - Re-instate IPAFrameContext with a sub-structure 'sensor' currently storing the exposure and gain value. Adapt the various access to the frame context to the new changes as described above. Subsequently, the re-instated IPAFrameContext will be extended to contain a frame number and ControlList to remember the incoming request controls provided by the application. A ring-buffer will be introduced to store these frame contexts for a certain number of frames.
