** Description changed: + [SRU Justification] + + [Impact] + + Unexpected noises caused by incorrect analog gain and digital gain + setting are found on Intel IPU6 camera platforms. + + [Fix] + + Fixes were released to both kernel and libcamhal library in following + GitHub repositories: + + * https://github.com/intel/ipu6-drivers/commit/f06a7aba2573b9ff53e7b186325c4e890066ee5d + * https://github.com/intel/ipu6-camera-hal/commit/768f8138a93e3e677c0e167e97205aac628c7580 + * https://github.com/intel/ipu6-camera-hal/commit/42727783f4a2a808d5d43484a5a7795d6c6d899f + + [Test Case] + + One may use some ordinary camera clients, e.g. cheeze, to examine the + output via V4L2 loopback relay, or use following command to access + hardware camera directly: + + $ sudo gst-launch-1.0 icamerasrc ! videoconvert ! xvimagesink + + `sudo` is required due to a WIP bug. + + [Where problems could occur] + + This kernel driver change updates only register settings on the camera + sensor currently only used on IPU6 platforms, so the effect to other + components/platforms should be limited. However, while the + kernel/libcamhal fixes must cooperate with each other, we do meet one + regression introduced by this change, and soon got fixed as the third + commit in aforementioned list. + + [Other Info] + + So far Intel has no plan to commit this driver to upstream yet, so it's + only nominated for oem-5.10. It will only be nominated to generic + kernels when the plan/requirements have changed. + + ========== original bug description ========== + Intel has a new release on camera IQ improvement at https://github.com/intel/ipu6-drivers/commit/f06a7aba2573b9ff53e7b186325c4e890066ee5d. Both changes to kernel and the user land libraries are included. Changes includes: 1. Fix noise caused by incorrect analog gain and digital gain setting. See - attachment[1]. + attachment[1]. 2.
