DXGK_NODEMETADATA structure (d3dkmdt.h)

  • Article

The DXGK_NODEMETADATA structure describes an engine on a GPU node.

Syntax

typedef struct _DXGK_NODEMETADATA {
  DXGK_ENGINE_TYPE        EngineType;
  WCHAR                   FriendlyName[DXGK_MAX_METADATA_NAME_LENGTH];
  DXGK_NODEMETADATA_FLAGS Flags;
  UINT32                  Reserved;
  BOOLEAN                 GpuMmuSupported;
  BOOLEAN                 IoMmuSupported;
} DXGK_NODEMETADATA;

Members

EngineType

A DXGK_ENGINE_TYPE enumeration value that indicates the engine type.

FriendlyName[DXGK_MAX_METADATA_NAME_LENGTH]

A NULL-terminated string that represents a descriptive friendly name for a particular engine.

The display miniport driver (KMD) must provide a value for this member if EngineType is DXGK_ENGINE_TYPE_OTHER. Otherwise, KMD should set this value to be an empty, NULL-terminated string.

This member doesn't need to be localized and can be represented with an EN-US string value.

Flags

A bit field of DXGK_NODEMETADATA_FLAGS values that describe the engine's metadata. This member is available starting in WDDM 2.2.

Reserved

Reserved for system use.

GpuMmuSupported

A Boolean value that indicates whether the graphics engines of the node support the GpuMmu model. Available starting in WDDM 2.0.

IoMmuSupported

A Boolean value that indicates whether the graphics engines of the node support the IoMmu model. Available starting in WDDM 2.0.

Remarks

This structure is used to define the structure DXGKARG_GETNODEMETADATA, in the call to KMD's DXGKDDI_GETNODEMETADATA.
