While at it in patch 10/11 we\nwill first cache the gamma value to apply in order to avoid unneeded\ncalculations, and eventually add the documentation in the latest 11/11.\n\nJean-Michel Hautbois (11):\n ipa: ipu3: Document IPAIPU3 class interface\n ipa: ipu3: Improve the documentation of BDS grid\n ipa: ipu3: Document IPAIPU3::configure\n ipa: ipu3: Document the IPAIPU3 class\n ipa: ipu3: Explicitly use the statistics parameter\n ipa: ipu3: awb: Add AWB class documentation\n ipu3: ipa: agc: Determine cell size from ipu3_uapi_awb_set_item\n ipa: ipu3: agc: Remove unused variable count\n ipa: ipu3: agc: Document AGC mean-based algorithm\n ipa: ipu3: tonemapping: Generate the LUT only on gamma change\n ipa: ipu3: tonemapping: Add the documentation for ToneMapping\n\n src/ipa/ipu3/algorithms/agc.cpp | 120 ++++++++++++++---\n src/ipa/ipu3/algorithms/agc.h | 2 +-\n src/ipa/ipu3/algorithms/awb.cpp | 33 +++++\n src/ipa/ipu3/algorithms/tone_mapping.cpp | 40 +++++-\n src/ipa/ipu3/ipa_context.h | 1 +\n src/ipa/ipu3/ipu3.cpp | 162 ++++++++++++++++++++++-\n 6 files changed, 330 insertions(+), 28 deletions(-)" }
