From f1b78bc036422f25a13e1e6b7f313b72ece1013f Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Mon, 18 Feb 2019 17:11:38 -0500 Subject: [PATCH] drm/amdgpu: Set DPM_FLAG_NEVER_SKIP when enabling PM-runtime commit d33158530660bc89be3cc870a2152e4e9a76cac7 upstream. Based on a similar patch from Rafael for radeon. When using ATPX to control dGPU power, the state is not retained across suspend and resume cycles by default. This can probably be loosened for Hybrid Graphics (_PR3) laptops where I think the state is properly retained.
