I've added a second patch which improves the locking as per\nour discussion. Actually - and I think we'd both failed to notice! -\nrestartAsync was always called with the lock held, so it's simply a\ncase of not holding the lock that long. (Looking back at the original\nverion of this code, Prepare and Process ran asynchronously too so\nmore locking was necessary.)\n\nLaurent, I've applied your \"Reviewed-by\" to the first and last\npatches, I think that was the intention. Obviously we await Naush next\nweek.\n\nBest regards\nDavid\n\nDavid Plowman (4):\n libcamera: ipa: raspberrypi: ALSC: Camera mode does not need to be\n atomic\n libcamera: ipa: raspberrypi: ALSC: Improve locking in a few places\n libcamera: ipa: raspberrypi: ALSC: Resample luminance table\n libcamera: ipa: raspberrypi: ALSC: Improve behaviour when camera mode\n changes\n\n src/ipa/raspberrypi/controller/rpi/alsc.cpp | 99 ++++++++++++++-------\n src/ipa/raspberrypi/controller/rpi/alsc.hpp | 5 +-\n 2 files changed, 70 insertions(+), 34 deletions(-)" }
