Subject: [PATCH] drm/amdgpu: Add mem sync flag for IB allocated by SA
Date: Tue, 20 Apr 2021 16:27:30 +0800 [thread overview]
Message-ID: <20210420082730.393818-1-Jinzhou.Su@amd.com> (raw)
The buffer of SA bo will be used by many cases. So better
to flush the cache of indirect buffer allocated by SA before
commit the IB.
