DmaCompleted
Structure used when InterruptType is DXGK_INTERRUPT_DMA_COMPLETED.
DmaCompleted.SubmissionFenceId
The DMA buffer fence identifier of the completed command. This identifier was assigned during a call to the driver's DXGKDDI_SUBMITCOMMAND function for the latest completed DMA buffer.
DmaCompleted.NodeOrdinal
The zero-based index of the node that generates the notification.
DmaCompleted.EngineOrdinal
The zero-based index of the engine, within the node that NodeOrdinal specifies, that generates the notification. For graphics adapters that are not part of a link, you should always set EngineOrdinal to 0. For graphics adapters that are part of a link, set EngineOrdinal to the adapter index of the adapter in the link that the interrupting engine belongs to.
DmaPreempted
Structure used when InterruptType is DXGK_INTERRUPT_DMA_PREEMPTED.

DmaPreempted.NodeOrdinal
The zero-based index of the node that generates the notification.
DmaPreempted.EngineOrdinal
The zero-based index of the engine, within the node that NodeOrdinal specifies, that generates the notification. For graphics adapters that are not part of a link, you should always set EngineOrdinal set to 0. For graphics adapters that are part of a link, set EngineOrdinal to the adapter index of the adapter in the link that the interrupting engine belongs to. The GPU scheduler determines that hardware preempted all commands between the preemption request and the submission that LastCompletedFenceId specifies.

Flags
A DXGKCB_NOTIFY_INTERRUPT_DATA_FLAGS structure that indicates whether the display miniport driver provides a physical adapter mask in a call to the DxgkCbNotifyInterrupt function.
Remarks
A miniport driver fills in DXGKARGCB_NOTIFY_INTERRUPT_DATA, and then uses the DXGKCB_SYNCHRONIZE_EXECUTION callback to sync with the interrupt. The SynchronizeRoutine parameter of the DXGKCB_SYNCHRONIZE_EXECUTION callback points to a miniport-implemented function that gets called by the OS when appropriate, and then the driver fills out the parameter info before calling back into the OS with the DXGKCB_NOTIFY_INTERRUPT callback. The OS then handles the interrupt, with the scheduler using information in the DXGK_MULTIPLANE_OVERLAY_VSYNC_INFO2 struct.
Depending on the value in the InterruptType member, the display miniport driver should set the appropriate union member in this structure. For example, for the end of a direct memory access (DMA) buffer fence, which corresponds to a value of DXGK_INTERRUPT_DMA_COMPLETED in InterruptType, the driver must set a value in the SubmissionFenceId member of the DmaCompleted member. This value should be the DMA buffer fence identifier, which the driver's DxgkDdiSubmitCommand function assigned to the just completed DMA buffer.
