DXGKDDI_SIGNALMONITOREDFENCE callback function

Description

Adds a GPU instruction to signal the paging monitored fence object to the DMA (direct memory access) buffer. This callback function is called from a Video memory management worker thread when submitting paging buffers, and from the application thread performing kernel submissions such as PresentBlt or RenderGdi. The OS passes a hint to the driver regarding the kernel submission type.

Parameters

`hContext`

Driver context handle for the context that generated the kernel submission.

`pSignalMonitoredFence`

Pointer to a DXGKARG_SIGNALMONITOREDFENCE structure that contains parameters to signal the monitored fence object.

Return value

Returns NTSTATUS.

Remarks

WDDM synchronization class:

Zero Level for RenderGdi and PresentBlt submission types.
First Level GPU Scheduler Class for BuildPagingBuffer submission type.
