DXGKDDI_DPC_ROUTINE callback function

Description

The DxgkDdiDpcRoutine function is called back at IRQL DISPATCH_LEVEL after the display miniport driver calls DxgkCbQueueDpc.

Parameters

MiniportDeviceContext [in]

A handle to a context block that is associated with a display adapter. The display miniport driver's DxgkDdiAddDevice function previously provided this handle to the Microsoft DirectX graphics kernel subsystem.

Remarks

Only one deferred procedure call (DPC) can be scheduled (at a given time) for a given display adapter.

If the display miniport driver is supporting several display adapters, the DxgkDdiDpcRoutine might be called in a reentrant fashion. That is, while DxgkDdiDpcRoutine is executing on one processor on behalf of a particular display adapter, it could be called again on another processor on behalf of a different display adapter.
