Subject: [PATCH AUTOSEL 5.4 06/52] drm/amdgpu: add cache flush workaround to gfx8 emit_fence
Date: Fri, 20 Dec 2019 09:29:08 -0500 [thread overview]
Message-ID: <20191220142954.9500-6-sashal@kernel.org> (raw)
In-Reply-To: <20191220142954.9500-1-sashal@kernel.org>
From: Pierre-Eric Pelloux-Prayer <pierre-eric.pelloux-prayer@amd.com>
[ Upstream commit bf26da927a1cd57c9deb2db29ae8cf276ba8b17b ]
The same workaround is used for gfx7.
Both PAL and Mesa use it for gfx8 too, so port this commit to
gfx_v8_0_ring_emit_fence_gfx.
