struct drm_vmw_fence_rep
@handle: Fence object handle for fence associated with a command submission. @mask: Fence flags relevant for this fence object. @seqno: Fence sequence number in fifo. A fence object with a lower seqno will signal the EXEC flag before a fence object with a higher seqno. This can be used by user-space to avoid kernel calls to determine whether a fence has signaled the EXEC flag. Note that @seqno will wrap at 32-bit. @passed_seqno: The highest seqno number processed by the hardware so far. This can be used to mark user-space fence objects as signaled, and to determine whether a fence seqno might be stale. @fd: FD associated with the fence, -1 if not exported @error: This member should've been set to -EFAULT on submission. The following actions should be take on completion: error == -EFAULT: Fence communication failed. The host is synchronized. Use the last fence id read from the FIFO fence register. error != 0 && error != -EFAULT: Fence submission failed. The host is synchronized. Use the fence_seq member. error == 0: All is OK, The host may not be synchronized. Use the fence_seq member.
