Description

DXGKARG_OPENNATIVEFENCE is the structure passed to DxgkDdiOpenNativeFence.

Members

`hGlobalNativeFence`

[in] Driver-assigned handle to the fence object created in the prior call to DxgkDdiCreateNativeFence.

`hLocalNativeFence`

[in/out] On input, the value of hLocalNativeFence 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 local fence object.

`hDevice`

[in] Driver handle for the parent device of this local fence object.

`CurrentValueGpuVa`

[in] Read/write mapping of the current value for the GPU in user process address space.

`MonitoredValueGpuVa`

[in] Read/write mapping of the monitored value for the GPU in user process address space.

`Flags`

[in] A DXGK_OPENNATIVEFENCE_FLAGS structure containing flags that indicate how to open the local GPU fence object.

`Reserved[32]`

Reserved for system use.
