Minimialistic implementation in 1/3 to keep things run same.\n\nPatch 2/3 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- Bound checking and overflow checks\n\nPatch 3/3 removes IPAFrameContext pointer requirement from\nAlgorithm::process() and use a frame number instead.\n\nThis is how the design I inferred from our previous discussions.\nThe documentation is a bit spread out between 1/3 and 2/3. This still\nneeds some fixing from my side (feel free to ignore for now).\n\nSmoke tested briefly by running on nautilus.\n\nUmang Jain (3):\n ipa: ipu3: Separate out frame context queue as a distinct class\n ipa: ipu3: ipa_context: Extend FCQueue::get()\n ipa: algorithm: process() should take in frame number instead of\n context\n\n src/ipa/ipu3/algorithms/af.cpp | 2 +-\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 | 2 +-\n src/ipa/ipu3/algorithms/tone_mapping.h | 2 +-\n src/ipa/ipu3/ipa_context.cpp | 118 ++++++++++++++++++++++-\n src/ipa/ipu3/ipa_context.h | 16 ++-\n src/ipa/ipu3/ipu3.cpp | 12 ++-\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 20 files changed, 166 insertions(+), 37 deletions(-)" }
