  • Article

The DXGKCB_NOTIFY_MPO_VSYNC_FLAGS structure contains the flags set by the driver to process a flip entry.

Syntax

typedef struct _DXGKCB_NOTIFY_MPO_VSYNC_FLAGS {
  union {
    struct {
      UINT PostPresentNeeded : 1;
      UINT Reserved : 31;
    };
    UINT Value;
  };
} DXGKCB_NOTIFY_MPO_VSYNC_FLAGS;

Members

PostPresentNeeded

The driver sets this flag to indicate that scheduler must call DxgkDdiPostMultiplaneOverlayPresent for this flip entry.

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 31 bits (0xFFFFFFFE) of the 32-bit Value member to zeros.

Value

The 32-bit value that indicates all of the flags set in the union.
