Dan, I suppose you could pick it up and squash it into your\nseries. I have it here so just so that I don't forget about it.\n\nThis series breaks the rkisp1 pipeline since it'll complain about\nnon-existant tuning files. There's a series coming imminently to address\nthat (though it'll only add a tuning file for imx335).\n\nPaul Elder (5):\n ipa: rkisp1: agc: Read histogram weights from tuning file\n ipa: rkisp1: agc: Add digital gain\n fixup: ipa: rkisp1: Remove bespoke Agc functions\n ipa: libipa: agc: Change luminance target to piecewise linear function\n ipa: rkisp1: agc: Plumb mode-selection and frame duration controls\n\n src/ipa/ipu3/algorithms/agc.cpp | 5 +-\n src/ipa/libipa/agc.cpp | 22 +++-\n src/ipa/libipa/agc.h | 7 +-\n src/ipa/rkisp1/algorithms/agc.cpp | 179 +++++++++++++++++++++++---\n src/ipa/rkisp1/algorithms/agc.h | 11 ++\n src/ipa/rkisp1/algorithms/algorithm.h | 2 +\n src/ipa/rkisp1/ipa_context.h | 7 +\n src/ipa/rkisp1/rkisp1.cpp | 12 ++\n 8 files changed, 213 insertions(+), 32 deletions(-)" }
