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.

2021-11-29ipa: libipa: Introduce Algorithm class templateJean-Michel Hautbois
The algorithms are using the same function names with specialized parameters. Instead of duplicating code, introduce a libipa Algorithm class which implements a base class with template parameters in libipa, and use it in each IPA. As we now won't need an algorithm class for each IPA, move the documentation to libipa, and make it agnostic of the IPA used. While at it, fix the IPU3::Algorithm::Awb documentation.

2021-11-24ipa: ipu3: Convert to pragma onceKieran Bingham
Remove the verbose #ifndef/#define/#endif pattern for maintaining header idempotency, and replace it with a simple #pragma once. This simplifies the headers, and prevents redundant changes when header files get moved.

2021-08-20ipa: ipu3: Add the functions to the Algorithm classJean-Michel Hautbois
Introduce three functions in the Algorithm class to manage algorithms: - configure which is called when IPA is configured only - prepare called on EventFillParams event at each frame when the request is queued - process called on EventStatReady event at each frame completion when the statistics have been generated. The existing AGC implementation already has a function named process(), though it has different arguments. Adding the new virtual process() interface causes a compiler warning due to the AGC implementation overloading a virtual function, even though the overload can be resolved correctly. Temporarily disable the warning in this commit to maintain bisection until the AGC is converted to the new interface.

2021-08-20ipa: move libipa::Algorithm to ipa/ipu3/algorithmsJean-Michel Hautbois
The abstract Algorithm class was originally placed in libipa as an attempt define a generic algorithm container. This was a little optimistic and pushed a bit far too early. Move the Algorithm class into the IPU3 which is the only user of the class, as we adapt it to support modular algorithm components for the IPU3. Not documenting the namespace may cause issues with Doxygen in libipa. The file libipa.cpp is thus created as an empty file for now, but we can leverage it in the future to add more global libipa documentation, and possibly code too.
