Subject: [PATCH 7/7] drm/amdgpu: update SDMA V4 microcode init
Date: Thu,  1 Aug 2019 14:50:44 -0500	[thread overview]
Message-ID: <20190801195044.10331-7-alexander.deucher@amd.com> (raw)
In-Reply-To: <20190801195044.10331-1-alexander.deucher-5C7GfCeVMHo@public.gmane.org>

From: John Clements <John.Clements@amd.com>

Removed loading duplicate instances of SDMA FW for Arcturus.
We use a single image for all instances.
