D3DKMTSignalSynchronizationObjectFromGpu function

D3DKMTSignalSynchronizationObjectFromGpu is used to signal a monitored fence. When a particular graphics processing unit (GPU) engine is not capable of writing a new monitored fence value directly using its GPU virtual address, the driver needs to flush its command buffer and issue a signal from GPU packet using D3DKMTSignalSynchronizationObjectFromGpu2. For Windows Display Driver Model (WDDM) v2 drivers, existing D3DKMTSignalSynchronizationObject and D3DKMTSignalSynchronizationObject2 callbacks are deprecated and will eventually be removed.
