drm/amdgpu: skip kfd suspend/resume for S0ix

2021-03-22T19:28:20Z

drm/amdgpu: skip CG/PG for gfx during S0ix

2021-03-22T19:27:59Z

Not needed as the device is in gfxoff state so the CG/PG state is handled just like it would be for gfxoff during runtime gfxoff. This should also prevent delays on resume.

drm/amdgpu: update comments about s0ix suspend/resume

2021-03-22T19:27:42Z

Provide and explanation as to why we skip GFX and PSP for S0ix. GFX goes into gfxoff, same as runtime, so no need to tear down and re-init. PSP is part of the always on state, so no need to touch it. Acked-by: Evan Quan Signed-off-by: Alex Deucher

drm/amdgpu/swsmu: skip gfx cgpg on s0ix suspend

2021-03-22T19:26:42Z

The SMU expects CGPG to be enabled when entering S0ix. with this we can re-enable SMU suspend. Acked-by: Evan Quan Signed-off-by: Alex Deucher

drm/amdgpu: re-enable suspend phase 2 for S0ix

2021-03-22T19:26:11Z

This really needs to be done to properly tear down the device. SMC, PSP, and GFX are still problematic, need to dig deeper into what aspect of them that is problematic. Acked-by: Evan Quan Signed-off-by: Alex Deucher

2021-03-22T19:24:02Z
