Subject: [PATCH] drm/amdgpu: Add mem sync flag for SDMA IB test
Date: Tue, 20 Apr 2021 10:23:40 +0800 [thread overview]
Message-ID: <20210420022340.365464-1-Jinzhou.Su@amd.com> (raw)
The buffer for SDMA IB test is allocated by sa bo
which may be used by other purpose. Better to flush
the cache before commit the IB.
