2022-09-27ipa: libipa: Pass a reference instead of pointer to Algorithm::process()Laurent Pinchart
Frame contexts will become the core component of IPA modules, always available to functions of the algorithms. To indicate and prepare for this, turn the frame context pointer passed to Algorithm::process() into a reference. The RkISP1 IPA module doesn't use frame contexts yet, so pass a dummy context for now. While at it, drop an unneeded [[maybe_unused]] from Agc::process() and add a missing parameter documentation for the frameContext argument to Awb::process().

2022-08-19ipa: rkisp1: Add manual color gainsPaul Elder
Add support for manually controlling the color gains on the rkisp1 IPA. To that end, add and plumb the AwbEnable and ColourGains controls. As per-frame controls aren't supported yet in the rkisp1 IPA, simply apply and perform checks on the controls immediately.

2022-07-20ipa: rkisp1: Drop unnecessary forward declarations and includesLaurent Pinchart
Forward declarations of IPACameraSensorInfo and inclusion of linux/rkisp1-config.h are not needed in headers that use them only for arguments to functions defined by the Algorithm base class, as inclusion of algorithm.h will bring the necessary declarations for function arguments. Drop them. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Florian Sylvestre <fsylvestre@baylibre.com> Reviewed-by: Umang Jain <umang.jain@ideasonboard.com>
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.

2022-03-28ipa: rkisp1: Introduce AWBJean-Michel Hautbois
The RkISP1 ISP calculates a mean value for Y, Cr and Cb at each frame. There is a RGB mode which could theoretically give us the values for R, G and B directly, but it seems to be failing right now. Convert those values into R, G and B and estimate the gain to apply in a grey world.
