drm/amdgpu: Add documentation for enforce isolation feature

2024-11-08T16:45:29Z

This feature enables process isolation on the graphics engine by serializing access to it and adding a cleaner shader which clears LDS (Local Data Store) and GPRs (General Purpose Registers) between jobs.

drm/amd/pm: add zero RPM stop temperature OD setting support for SMU13

2024-11-05T15:33:47Z

Together with the feature to enable or disable zero RPM in the last commit, it also makes sense to expose the OD setting determining under which temperature the fan should stop if zero RPM is enabled. Reviewed-by: Kenneth Feng Signed-off-by: Wolfgang Müller Signed-off-by: Alex Deucher

drm/amd/pm: add zero RPM OD setting support for SMU13

2024-11-05T15:33:30Z

Whilst we have support for setting fan curves there is no support for disabling the zero RPM feature. Since the relevant bits are already present in the OverDriveTable, hook them up to a sysctl setting so users can influence this behaviour.

drm: zynqmp_dp: Add debugfs interface for compliance testing

2024-10-30T12:21:07Z

Add a debugfs interface for exercising the various test modes supported by the DisplayPort controller. This allows performing compliance testing, or performing signal integrity measurements on a failing link. At the moment, we do not support sink-driven link quality testing, although such support would be fairly easy to add. Additionally, add some debugfs files for ignoring AUX errors and HPD events, as this can allow testing with equipment that cannot emulate a DPRX.
