DXGK_SETVIDPNSOURCEADDRESS_OUTPUT_FLAGS structure (d3dkmddi.h)

The DXGK_SETVIDPNSOURCEADDRESS_OUTPUT_FLAGS structure contains the flags used to set the VidPN source address.

Syntax

typedef struct _DXGK_SETVIDPNSOURCEADDRESS_OUTPUT_FLAGS {
  union {
    struct {
      UINT PrePresentNeeded : 1;
      UINT HwFlipQueueDrainNeeded : 1;
      UINT HwFlipQueueDrainAllPlanes : 1;
      UINT HwFlipQueueDrainAllSources : 1;
#if ...
      UINT Reserved : 28;
#else
      UINT Reserved : 31;
#endif
    };
    UINT Value;
  };
} DXGK_SETVIDPNSOURCEADDRESS_OUTPUT_FLAGS;

Members

PrePresentNeeded

Indicates that the driver must be called again at the PASSIVE_LEVEL to perform the requested operation.

HwFlipQueueDrainNeeded

Indicates that the OS should attempt to submit the flip request again after all pending flips on planes affected by this flip are finished and once the target time is reached. See Hardware flip queue for more information.

HwFlipQueueDrainAllPlanes

Indicates that the display hardware may require completion of pending flips on all planes, not just the ones referenced by the incoming flip request. In this case, the driver should set both the HwFlipQueueDrainNeeded and HwFlipQueueDrainAllPlanes. See Hardware flip queue for more information.

HwFlipQueueDrainAllSources

Indicates that the display hardware may require completion of pending flips on all VidPn sources in order to reallocate internal resources. In this case, the driver should set both the HwFlipQueueDrainNeeded and HwFlipQueueDrainAllSources flags. See Hardware flip queue for more information.

Reserved

This member is reserved and should be set to zero.

Value

An alternative way to access the bits.
