drm/amdgpu: initialize vm_inv_eng0_sem for gfxhub and mmhub

2019-11-22T19:55:19+00:00

SW must acquire/release one of the vm_invalidate_eng*_sem around the invalidation req/ack. Through this way,it can avoid losing invalidate acknowledge state across power-gating off cycle. To use vm_invalidate_eng*_sem, it needs to initialize vm_invalidate_eng*_sem firstly. Signed-off-by: changzhu Reviewed-by: Christian König Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org
