Subject: [PATCH 1/2] drm/amdgpu/gfx7: enable cp/rlc ints after we disable clockgating
Date: Mon, 10 Apr 2017 17:45:57 -0400	[thread overview]
Message-ID: <1491860758-22182-1-git-send-email-alexander.deucher@amd.com> (raw)

Even if we disable clockgating, we still need to make sure the
cp/rlc interrupts are enabled for powergating which might still
be enabled.
