The hardcoded AF starting area was removed and\nbdsOutputSize was used to determine start_x and start_y axis.\n\nPatch v3 squashed Daniel's commit to remove the V4l2 control from the\nalgorithm. Also, params->acc_param.af is simplified by using kernel's\ndefault configuration. Since the V4l2 configuration had been removed,\nthe greedy algorithm is revised to fix some errors. Now, the AF area\nis determined by the bdsOutputSize.\n\nThere is still some issues of bdsOutputSize to determine the AF\nstart position. bdsOutputSize gives a 1440x960 size of the image but\nthe output format is 1280x720. If the position is based on it, it will\nbe shifted left for 80px. \n\nKate Hsuan (1):\n ipa: ipu3: af: Auto focus for dw9719 Surface Go2 VCM\n\n src/ipa/ipu3/algorithms/af.cpp | 239 ++++++++++++++++++++++++++++\n src/ipa/ipu3/algorithms/af.h | 53 ++++++\n src/ipa/ipu3/algorithms/meson.build | 3 +-\n src/ipa/ipu3/ipa_context.cpp | 27 ++++\n src/ipa/ipu3/ipa_context.h | 11 ++\n src/ipa/ipu3/ipu3.cpp | 2 +\n 6 files changed, 334 insertions(+), 1 deletion(-)\n create mode 100644 src/ipa/ipu3/algorithms/af.cpp\n create mode 100644 src/ipa/ipu3/algorithms/af.h" }
