[PATCH] drm/amdgpu: Use real power source in powerplay instand of hardcode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



1. move ac_power to struct pm from dpm, so can be shared with powerplay
2. remove power_source in powerplay, use adev->pm.ac_power instand.
3. update ac_power before dispatch power task.
