for SR-IOV, we must keep the pipeline-sync in the protection of COND_EXEC, otherwise the command consumed by CPG is not consistent when world switch triggerd, e.g.: world switch hit and the IB frame is skipped so the fence won't signal, thus CP will jump to the next DMAframe's pipeline-sync command, and it will make CP hang foever. after pipelin-sync moved into COND_EXEC the consistency can be guaranteed Signed-off-by: Monk Liu <Monk.Liu@amd.com> Reviewed-by: Christian König <christian.koenig@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> |
