DXGK_RECOMMENDVIDPNTOPOLOGY_REASON enumeration (d3dkmddi.h)

  • Article

The DXGK_RECOMMENDVIDPNTOPOLOGY_REASON enumeration indicates the reason for calling the display miniport driver's DxgkDdiRecommendVidPnTopology function.

Syntax

typedef enum _DXGK_RECOMMENDVIDPNTOPOLOGY_REASON {
  DXGK_RVT_UNINITIALIZED,
  DXGK_RVT_INITIALIZATION_NOLKG,
  DXGK_RVT_AUGMENTATION_NOLKG,
  DXGK_RVT_AUGMENTATION_LKGOVERRIDE,
  DXGK_RVT_INITIALIZATION_LKGOVERRIDE
} DXGK_RECOMMENDVIDPNTOPOLOGY_REASON;

Constants

 
DXGK_RVT_UNINITIALIZED
Indicates that a variable of type DXGK_RECOMMENDVIDPNTOPOLOGY_REASON has not yet been assigned a meaningful value.
DXGK_RVT_INITIALIZATION_NOLKG
Indicates that the call is being made during the initialization of the display adapter after an attempt to use the last known good VidPN topology failed.
DXGK_RVT_AUGMENTATION_NOLKG
Indicates that the call is being made during the VidPN topology augmentation by the display mode manager (DMM) after an attempt to use the last known good VidPN topology failed.
DXGK_RVT_AUGMENTATION_LKGOVERRIDE
Indicates that the call is being made during the VidPN topology augmentation by the display mode manager (DMM), giving the display miniport driver a chance to override the last known good VidPN topology.
DXGK_RVT_INITIALIZATION_LKGOVERRIDE
Indicates that the call is being made during the initialization of the display adapter, giving the display miniport driver a chance to override the last known good VidPN topology.
