[PATCH 15/21] drm/amdgpu: disentangle runtime pm and vga_switcheroo

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

 



Originally we only supported runtime pm on PX/HG laptops
so vga_switcheroo and runtime pm are sort of entangled.

Attempt to logically separate them.
