[PATCH v2] drm/amd/powerplay: add limit of pp_feature for smu (v2)

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

 



From: Likun Gao <Likun.Gao@xxxxxxx>

Move pp_feature from the struct of amd_powerplay to amdgpu_device.
Add pp_feature limit for overdrive interface.

v2: put pp_feature into struct amdgpu_pm.
