Description

DXGKARG_CREATENATIVEFENCE is the structure passed to DxgkDdiCreateNativeFence to describe a native GPU fence.

Members

`hGlobalNativeFence`

[in/out] On input, the value of hGlobalNativeFence is the Dxgkrnl-generated handle of the object.

On output, the value returned by the KMD is the internal, KMD-maintained handle to be used by subsequent callbacks to refer to this native GPU fence object.

`Type`

[in] A D3DDDI_NATIVEFENCE_TYPE value that indicates the type of native GPU fence object to create.

`CurrentValueSystemProcessGpuVa`

[in] Read/write mapping of the current value for the GPU in system process address space. The OS has does this mapping only if KMD has set the DXGK_NATIVE_FENCE_CAPS::MapToGpuSystemProcess cap to TRUE.

`MonitoredValueSystemProcessGpuVa`

[in] Read/write mapping of the monitored value for the GPU in system process address space. The OS has does this mapping only if KMD has set the DXGK_NATIVE_FENCE_CAPS::MapToGpuSystemProcess cap to TRUE.

`pPrivateDriverData[D3DDDI_NATIVE_FENCE_PDD_SIZE]`

[in/out] Pointer to the private driver data from the user-mode CreateNativeFence call, copied back to UMD.

`Flags`

[in] A DXGKARG_CREATENATIVEFENCE_FLAGS structure containing flags to use when creating the native GPU fence object.

`Reserved[32]`

Reserved for system use.
