I hope it is ready to go. Most\nof the patches have 2 rby tags. I repost because patch 6 and 7 were\nreworked. Patch 6 contains the error message when queuing parameter\nbuffers fails. The functionality to check for available parameter types\nwas pulled into linux 6.17. I therefore reduced the error message in\npatch 6 to a generic \"Failed to queue parameter buffer\" as this might\nstill be valuable information even though it is not expected to happen\nregularly. Patch 7 was simplified as result of the reviews and therefore\nmisses the rby tags.\n\nBest regards,\nStefan\n\n--- Old cover letter below.\n\nThis v2 fixes a few minor errors found in v1. The main reason for the\nrepost is to create a basis for the upcoming WDR series.\n\nThe rest of the text here is unmodified (the changelogs are in the\npatches).\n\nThis patch series does a bit of preparatory work for the upcoming WDR\nsupport. The patches are a mix of topics but as they are all quite\nsmall, I thought that a small series might be the best fit.\n\nPatches 1-3 are tiny improvements in gen-debug-controls that ease the\nday to day work.\n\nPatches 4 and 7 add a bit of debug logging.\n\nPatches 5-6 fix a bug in the rkisp1 parameters handling.\n\nPatches 8-9 add support for exposure compensation in rkisp1.\n\nI hope you all like it :-)\n\nBest regards,\nStefan\n\nStefan Klug (9):\n utils: gen-debug-controls: Remove line number from control description\n utils: gen-debug-controls: Fix handling of controls that appear\n multiple times\n utils: gen-debug-controls: Improve log output\n libipa: agc_mean_luminance: Add debug logging\n ipa: rkisp1: params: Check for empty parameters\n pipeline: rkisp1: Add error log when parameter queuing fails\n pipeline: v4l2_subdevice: Add color space to format string\n representation\n libipa: agc_mean_luminance: Add exposure compensation support\n ipa: rkisp1: agc: Implement ExposureValue control\n\n src/ipa/libipa/agc_mean_luminance.cpp | 36 +++++++++++++++++++++---\n src/ipa/libipa/agc_mean_luminance.h | 6 ++++\n src/ipa/rkisp1/algorithms/agc.cpp | 10 +++++++\n src/ipa/rkisp1/ipa_context.h | 2 ++\n src/ipa/rkisp1/params.cpp | 3 ++\n src/ipa/rkisp1/params.h | 3 ++\n src/libcamera/pipeline/rkisp1/rkisp1.cpp | 9 +++++-\n src/libcamera/v4l2_subdevice.cpp | 2 ++\n utils/gen-debug-controls.py | 28 +++++++++++++++---\n 9 files changed, 90 insertions(+), 9 deletions(-)" }
