Subject: [PATCH 8/8] drm/amdgpu: allow fragment processing for invalid PTEs
Date: Wed, 12 Sep 2018 10:54:45 +0200	[thread overview]
Message-ID: <20180912085445.3245-8-christian.koenig@amd.com> (raw)
In-Reply-To: <20180912085445.3245-1-christian.koenig-5C7GfCeVMHo@public.gmane.org>

That should improve the PRT performance on Vega quite a bit.
