drm/amdgpu: Move reset sem into reset_domain

2022-02-09T17:17:32+00:00

We want single instance of reset sem across all reset clients because in case of XGMI we should stop access cross device MMIO because any of them could be in a reset in the moment.

2022-01-18T22:43:36+00:00

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code, thus a matching decrement is needed on the error handling path to keep the counter balanced. Signed-off-by: Yongzhi Liu Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher

drm/amd/pm: do not expose implementation details to other blocks out of power

2022-01-14T22:51:14+00:00

Those implementation details(whether swsmu supported, some ppt_funcs supported, accessing internal statistics ...)should be kept internally. It's not a good practice and even error prone to expose implementation details. Signed-off-by: Evan Quan Reviewed-by: Lijo Lazar Signed-off-by: Alex Deucher
