Subject: [PATCH 2/4] drm/amdgpu: expose only the first UVD instance for now
Date: Mon, 23 Jul 2018 17:14:39 +0200	[thread overview]
Message-ID: <20180723151441.46790-2-christian.koenig@amd.com> (raw)
In-Reply-To: <20180723151441.46790-1-christian.koenig-5C7GfCeVMHo@public.gmane.org>

Going to completely rework the context to ring mapping with Nayan's GSoC
work, but for now just stopping to expose the second UVD instance should
do it.
