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 *CurrentValueCpuVa;
D3DKMT_ALIGN64 D3DGPU_VIRTUAL_ADDRESS CurrentValueGpuVa;
D3DKMT_ALIGN64 D3DGPU_VIRTUAL_ADDRESS MonitoredValueGpuVa;
D3DKMT_ALIGN64 BYTE Reserved[32];
} D3DDDI_NATIVEFENCEMAPPING;
Members
CurrentValueCpuVa
Read-only mapping of the current value for the CPU. This value is is used by user-mode components to poll the native fence CurrentValue.
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.
