D3DKMT_OPENNATIVEFENCEFROMNTHANDLE structure (d3dkmthk.h)

  • Artikkel

The D3DKMT_OPENNATIVEFENCEFROMNTHANDLE structure is a parameter for the D3DKMTOpenNativeFenceFromNTHandle function. It describes the native fence to open.

Syntax

typedef struct _D3DKMT_OPENNATIVEFENCEFROMNTHANDLE {
  HANDLE                                                           hNtHandle;
  D3DKMT_HANDLE                                                    hDevice;
  UINT                                                             EngineAffinity;
  D3DDDI_SYNCHRONIZATIONOBJECT_FLAGS                               Flags;
  D3DKMT_HANDLE                                                    hSyncObject;
  D3DDDI_NATIVEFENCEMAPPING                                        NativeFenceMapping;
  BYTE                                                             PrivateDriverData[D3DDDI_NATIVE_FENCE_PDD_SIZE];
  to pass to KMD DdiOpenNativeFence call and copy back to UMD BYTE Reserved[32];
} D3DKMT_OPENNATIVEFENCEFROMNTHANDLE;

Members

hNtHandle

[in] NT handle for the shared fence object.

hDevice

[in] Device handle to open this fence object on.

EngineAffinity

[in] Defines the physical adapters where the GPU virtual address is mapped.

Flags

[in] A D3DDDI_SYNCHRONIZATIONOBJECT_FLAGS structure that identifies the attributes of the synchronization object.

hSyncObject

[out] Handle to the opened fence object.

NativeFenceMapping

[out] A D3DDDI_NATIVEFENCEMAPPING structure that contains process mapping information for the fence object.

PrivateDriverData[D3DDDI_NATIVE_FENCE_PDD_SIZE]

Reserved[32]

Reserved for system use.
