Minimialistic implementation in 1/4 to keep things run same.\n\nPatch 2/4 extends the .get() function to handle cases as :\n- Return same IPAFrameContext if previously created\n- Assign a new IPAFrameContext if the frame contexts for frame didn't\n exists\n- isFull() detection\n\nPatch 3/4 implements a mechanism to prevent overflowing the FCQueue\n\nPatch 4/4 removes IPAFrameContext pointer requirement from\nAlgorithm::process() and use a frame number instead.\n\nSmoke tested briefly by running on nautilus.\n\nUmang Jain (4):\n ipa: ipu3: Separate out frame context queue as a distinct class\n ipa: ipu3: ipa_context: Extend FCQueue::get()\n ipa: ipu3: Prevent over queuing of requests\n ipa: algorithm: process() should take in frame number instead of\n context\n\n include/libcamera/ipa/ipu3.mojom | 2 +-\n src/ipa/ipu3/algorithms/af.cpp | 4 +-\n src/ipa/ipu3/algorithms/af.h | 2 +-\n src/ipa/ipu3/algorithms/agc.cpp | 13 ++-\n src/ipa/ipu3/algorithms/agc.h | 4 +-\n src/ipa/ipu3/algorithms/algorithm.h | 4 +-\n src/ipa/ipu3/algorithms/awb.cpp | 2 +-\n src/ipa/ipu3/algorithms/awb.h | 2 +-\n src/ipa/ipu3/algorithms/tone_mapping.cpp | 4 +-\n src/ipa/ipu3/algorithms/tone_mapping.h | 2 +-\n src/ipa/ipu3/ipa_context.cpp | 138 ++++++++++++++++++++++-\n src/ipa/ipu3/ipa_context.h | 20 +++-\n src/ipa/ipu3/ipu3.cpp | 33 ++++--\n src/ipa/libipa/algorithm.cpp | 2 +-\n src/ipa/libipa/algorithm.h | 6 +-\n src/ipa/rkisp1/algorithms/agc.cpp | 3 +-\n src/ipa/rkisp1/algorithms/agc.h | 2 +-\n src/ipa/rkisp1/algorithms/algorithm.h | 5 +-\n src/ipa/rkisp1/algorithms/awb.cpp | 2 +-\n src/ipa/rkisp1/algorithms/awb.h | 2 +-\n src/ipa/rkisp1/rkisp1.cpp | 2 +-\n src/libcamera/pipeline/ipu3/ipu3.cpp | 10 +-\n 22 files changed, 216 insertions(+), 48 deletions(-)"}
