The definition of AeState is also made more concrete. The\nfirst two patches add the new controls, as well as documentation and\ndesign rationale.\n\nThe rest of the patches naturally update the existing users of AeEnable,\nbefore finally removing the control altogether.\n\nv4 mainly improves documentation and implements the proper behavior when\ntransitioning between auto and manual modes for the rkisp1.\n\nv5 is mostly minor wording changes, plus a fix to the rkisp1 aegc\nimplementation to support mixed manual-auto ae modes (aka \"shutter\npriority\" / \"gain priority\").\n\nThanks,\n\nPaul\n\nJacopo Mondi (4):\n libcamera: uvcvideo: Register ExposureTimeMode control\n test: ipa_data_serialization: Use DebugMetadataEnable\n ipa: raspberry: Port to the new AEGC controls\n controls: Remove AeEnable and AeLocked\n\nPaul Elder (4):\n controls: Introduce AEGC-related controls\n Documentation: design: ae: Document the design for AE controls\n ipa: rkisp1: Port to the new AEGC controls\n gstreamer: Generate the new AEGC controls\n\n Documentation/design/ae.rst | 320 ++++++++++++++++++\n Documentation/index.rst | 4 +-\n Documentation/meson.build | 1 +\n src/ipa/rkisp1/algorithms/agc.cpp | 122 +++++--\n src/ipa/rkisp1/ipa_context.cpp | 24 +-\n src/ipa/rkisp1/ipa_context.h | 8 +-\n src/ipa/rpi/common/ipa_base.cpp | 74 +++-\n src/ipa/rpi/controller/agc_algorithm.h | 8 +-\n src/ipa/rpi/controller/rpi/agc.cpp | 52 ++-\n src/ipa/rpi/controller/rpi/agc.h | 8 +-\n src/ipa/rpi/controller/rpi/agc_channel.cpp | 24 +-\n src/ipa/rpi/controller/rpi/agc_channel.h | 8 +-\n src/libcamera/control_ids_core.yaml | 268 +++++++++++++--\n src/libcamera/control_ids_draft.yaml | 29 --\n src/libcamera/pipeline/uvcvideo/uvcvideo.cpp | 53 ++-\n .../ipa_data_serializer_test.cpp | 2 +-\n utils/codegen/gen-gst-controls.py | 5 +-\n 17 files changed, 890 insertions(+), 120 deletions(-)\n create mode 100644 Documentation/design/ae.rst" }
