D3DDDI_NATIVEFENCEMAPPING structure (d3dukmdt.h)

The D3DDDI_NATIVEFENCEMAPPING structure contains native GPU fence address mappings in the caller's process address space.

Syntax

typedef struct _D3DDDI_NATIVEFENCEMAPPING {
  void                                  D3DKMT_PTR(
    VOID              *unnamedParam1,
    CurrentValueCpuVa unnamedParam2
  );
  D3DKMT_ALIGN64 D3DGPU_VIRTUAL_ADDRESS CurrentValueGpuVa;
  D3DKMT_ALIGN64 D3DGPU_VIRTUAL_ADDRESS MonitoredValueGpuVa;
  D3DKMT_ALIGN64 BYTE                   Reserved[32];
} D3DDDI_NATIVEFENCEMAPPING;

Members

void D3DKMT_PTR( VOID *unnamedParam1, CurrentValueCpuVa unnamedParam2)

CurrentValueGpuVa

Read/write mapping of the current value for the GPU in the current process's address space. This value is used by the GPU engine to read or write to the native fence CurrentValue as a fence signal operation.

MonitoredValueGpuVa

Read/write mapping of the monitored value for the GPU in the current process's address space. This value is used by the GPU engine to check whether a conditional CPU interrupt should be raised.

Reserved[32]

Reserved for system use.
