IDStorageQueueX::EnqueueSignal
Enqueues a fence write.Syntax
Parameters
fenceType: ID3D12Fence An
ID3D12Fence to enqueue.
valueType: UINT64 The value to write to the fence.
Return value
Type: voidRemarks
The fence is signaled when all requests enqueued before the fence complete. A title thread can wait for the fence or poll the fence. The GPU can also poll the fence. If theEnqueueSignal method fills half of the queue’s capacity since the last
submission, it triggers an automatic submission as part of the EnqueueSignal
call.
In most cases, this method simply does a memory write to the queue, thus takes
very little CPU time to complete. However, if automatic submission is triggered,
it takes significantly more CPU time, including a kernel mode transition and
processing all of the previously submitted requests in the caller thread.
If automatic submission is not desirable, games are recommended to use a queue
with large enough capacity and call Submit manually
when appropriate.
