DXGK_DISPLAY_DIAGNOSTICS_INTERFACE structure (dispmprt.h)

A kernel-mode component that needs to use the display diagnostics interface calls the display miniport driver's DxgkDdiQueryInterface function.

Syntax

typedef struct _DXGK_DISPLAY_DIAGNOSTICS_INTERFACE {
  [in]  IN USHORT                               Size;
  [in]  IN USHORT                               Version;
  [out] OUT PVOID                               Context;
  [out] OUT PINTERFACE_REFERENCE                InterfaceReference;
  [out] OUT PINTERFACE_DEREFERENCE              InterfaceDereference;
  [out] OUT DXGKDDI_GETDISPLAYSTATENONINTRUSIVE DxgkDdiGetDisplayStateNonIntrusive;
  [out] OUT DXGKDDI_GETDISPLAYSTATEINTRUSIVE    DxgkDdiGetDisplayStateIntrusive;
} DXGK_DISPLAY_DIAGNOSTICS_INTERFACE, *PDXGK_DISPLAY_DIAGNOSTICS_INTERFACE;

Members

[in] Size

Size, in bytes, of this structure.

[in] Version

Version number of the display diagnostics interface. Version number constants are defined in dispmprt.h (for example, DXGK_DISPLAY_DIAGNOSTICS_INTERFACE_VERSION_1).

[out] Context

Pointer to a private context block provided by the display miniport driver. The operating system will provide this Context back to the driver in interface DDI calls. The driver should ensure that this context is adapter-specific and not driver-global because the operating system stores the interface information per adapter.

[out] InterfaceReference

Pointer to the display miniport driver's interface reference function.

[out] InterfaceDereference

Pointer the display miniport driver's interface dereference function.

[out] DxgkDdiGetDisplayStateNonIntrusive

Pointer to the display miniport driver's DxgkDdiGetDisplayStateNonIntrusive function.

[out] DxgkDdiGetDisplayStateIntrusive

Pointer to the display miniport driver's DxgkDdiGetDisplayStateIntrusive function.

Remarks

The operating system will query the display diagnostics interface for each graphics adapter when they are started.
