The effective sensor\ncontrols can then be reported with patch 8/11.\n\nPatch 9/11 is a small adaptation of the IPU3 AGC: we reuse the relative\nluminance estimation, basing it on the Y mean measured by the ISP, and\nremoves the histogram based calculation for now.\n\nIn v2 the improvements from Laurent's series \"ipa: ipu3: agc: Misc\nimprovements\" are also included.\n\nPatch 10/11 introduces a new prepare() call from the Algorithm class in\nAGC, and patch 11/11 is making it revision independant.\n\nJean-Michel Hautbois (11):\n libipa: Correct IMX219 in CameraSensorHelper\n ipa: rkisp1: Pass IPASettings at init call\n ipa: Do not modify the sensor limits\n ipa: rkisp1: Instantiate CameraSensorHelper\n ipa: rkisp1: Introduce IPAContext\n ipa: libipa: Introduce Algorithm class template\n ipa: rkisp1: Use the Algorithm class\n ipa: rkisp1: Report and use sensor controls\n ipa: rkisp1: Introduce AGC\n ipa: rkisp1: agc: Introduce prepare call\n ipa: rkisp1: agc: Configure the number of cells used by HW\n\n include/libcamera/ipa/rkisp1.mojom | 6 +-\n src/ipa/ipu3/algorithms/algorithm.h | 12 +-\n src/ipa/ipu3/algorithms/awb.cpp | 9 +\n src/ipa/ipu3/algorithms/meson.build | 1 -\n src/ipa/ipu3/ipu3.cpp | 4 +-\n .../{ipu3/algorithms => libipa}/algorithm.cpp | 38 +--\n src/ipa/libipa/algorithm.h | 41 +++\n src/ipa/libipa/camera_sensor_helper.cpp | 2 +-\n src/ipa/libipa/meson.build | 1 +\n src/ipa/rkisp1/algorithms/agc.cpp | 282 ++++++++++++++++++\n src/ipa/rkisp1/algorithms/agc.h | 58 ++++\n src/ipa/rkisp1/algorithms/algorithm.h | 28 ++\n src/ipa/rkisp1/algorithms/meson.build | 5 +\n src/ipa/rkisp1/ipa_context.cpp | 110 +++++++\n src/ipa/rkisp1/ipa_context.h | 53 ++++\n src/ipa/rkisp1/meson.build | 11 +-\n src/ipa/rkisp1/rkisp1.cpp | 128 ++++----\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 5 +-\n 18 files changed, 703 insertions(+), 91 deletions(-)\n rename src/ipa/{ipu3/algorithms => libipa}/algorithm.cpp (75%)\n create mode 100644 src/ipa/libipa/algorithm.h\n create mode 100644 src/ipa/rkisp1/algorithms/agc.cpp\n create mode 100644 src/ipa/rkisp1/algorithms/agc.h\n create mode 100644 src/ipa/rkisp1/algorithms/algorithm.h\n create mode 100644 src/ipa/rkisp1/algorithms/meson.build\n create mode 100644 src/ipa/rkisp1/ipa_context.cpp\n create mode 100644 src/ipa/rkisp1/ipa_context.h" }
