DxgkDdiOpenNativeFence is called by the OS to open a native GPU fence object.
hAdapter[in] A handle to a context block associated with a display adapter. The display miniport driver previously provided this handle to Dxgkrnl in the MiniportDeviceContext output parameter of the DXGKDDI_ADD_DEVICE function.
pOpenNativeFence[in/out] Pointer to a DXGKARG_OPENNATIVEFENCE structure that describes the native GPU fence to open.
DxgkDdiOpenNativeFence returns STATUS_SUCCESS if KMD was able to successfully open a native GPU fence object. Otherwise, it returns an appropriate NTSTATUS error code.
DxgkDdiOpenNativeFence is always preceded by a call to DxgkDdiCreateNativeFence.
If a second process opens the shared native fence object using D3DKMT_OPENNATIVEFENCEFROMNTHANDLE, Dxgkrnl does the following:
Dxgkrnl passes this payload to the KMD by calling DxgkDdiOpenNativeFence along with a new hLocalNativeFence handle.
