Subject: [PATCH AUTOSEL 5.2 025/171] drm/amdgpu/sriov: Need to initialize the HDP_NONSURFACE_BAStE
Date: Thu, 18 Jul 2019 23:54:16 -0400	[thread overview]
Message-ID: <20190719035643.14300-25-sashal@kernel.org> (raw)
In-Reply-To: <20190719035643.14300-1-sashal-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>

From: Tiecheng Zhou <Tiecheng.Zhou@amd.com>

[ Upstream commit fe2b5323d2c3cedaa3bf943dc7a0d233c853c914 ]

it requires to initialize HDP_NONSURFACE_BASE, so as to avoid
using the value left by a previous VM under sriov scenario.

v2: it should not hurt baremetal, generalize it for both sriov
and baremetal
