It then reports it to Android.\n\nPaul: I didn't manage to reproduce the error on you in-development CTS patches\nso I can't say this series fixes the test. But I've manually collected the\nreported duration and run them through a little script and verified they all\nfall in the expected range. Could you test your failing test with this series\non top ?\n\nThanks\n j\n\nJacopo Mondi (3):\n libcamera: controls: Destage 'SensorTimestamp'\n libcamera: ipu3: Report sensor timestamp\n android: camera_device: Use controls::SensorTimestamp\n\n src/android/camera_device.cpp | 33 +++++++++++++++++-----------\n src/android/camera_device.h | 3 +--\n src/libcamera/control_ids.yaml | 21 ++++++++++++------\n src/libcamera/pipeline/ipu3/ipu3.cpp | 9 ++++++++\n 4 files changed, 44 insertions(+), 22 deletions(-)\n\n--\n2.31.1" }
