From 10cb67eb8a1b21419a7cd8e12f002a36bfef12fd Mon Sep 17 00:00:00 2001 From: Pratik Vishwakarma <Pratik.Vishwakarma@amd.com> Date: Tue, 16 Mar 2021 14:15:44 -0400 Subject: [PATCH] drm/amdgpu: skip CG/PG for gfx during S0ix 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.
