DXGKARG_SIGNALMONITOREDFENCE structure (d3dkmddi.h)

Arguments used by the DXGKDDI_SIGNALMONITOREDFENCE callback function to add a GPU instruction to signal the paging monitored fence object to the DMA buffer.

Syntax

typedef struct _DXGKARG_SIGNALMONITOREDFENCE {
  DXGK_KERNEL_SUBMISSION_TYPE KernelSubmissionType;
  VOID                        *pDmaBuffer;

  UINT                        DmaBufferPrivateDataSize;
  UINT                        MultipassOffset;
  D3DGPU_VIRTUAL_ADDRESS      MonitoredFenceGpuVa;
  UINT64                      MonitoredFenceValue;

Members

KernelSubmissionType

Describes what type of kernel submission is being performed. This information can be used by the driver to choose the right synchronization class, and to ensure fence write instruction is generated in the format compatible with the buffer type being used.

pDmaBuffer

A pointer to the start of the DMA buffer, which is aligned on 4 KB.

DmaBufferGpuVirtualAddress

A D3DGPU_VIRTUAL_ADDRESS data type that indicates the virtual address where the DMA buffer was paged in. If the physical address is zero, the DMA buffer is not correctly paged in.

DmaSize

The size, in bytes, of the DMA buffer that pDmaBuffer points to.

pDmaBufferPrivateData

A pointer to a driver-resident private data structure that is used for generating the DMA buffer that pDmaBuffer points to.

DmaBufferPrivateDataSize

The number of bytes that remain in the private data structure that pDmaBufferPrivateData points to for the current operation.

MultipassOffset

A value that specifies the progress of the rendering operation.

MonitoredFenceGpuVa

GPU VA of the monitored fence value to be updated.

MonitoredFenceValue

Fence value to write from the DMA buffer being built.

MonitoredFenceCpuVa

Kernel mode CPU VA of the monitored fence value to be updated.

hHwQueue

Handle to the hardware queue that the DMA buffer will be submitted to.
