+Subject: [PATCH 1063/1110] drm/amdgpu: add pipeline sync for compute job
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+hardware ring is async processed, the job is executed in parelell.
+In some case, this will result vm fault, like jobs with different vmids.
