DXGK_PRESENTMULTIPLANEOVERLAYLIST structure (d3dkmddi.h)

  • Article

Specifies an overlay plane to display in a call to the DxgkDdiPresent function.

Syntax

typedef struct _DXGK_PRESENTMULTIPLANEOVERLAYLIST {
       UINT             LayerIndex;
       BOOL             Enabled;
       HANDLE           hDeviceSpecificAllocation;
  struct {
    [in] UINT SegmentId : 5;
         UINT Reserved : 27;
  };
  [in] PHYSICAL_ADDRESS PhysicalAddress;
} DXGK_PRESENTMULTIPLANEOVERLAYLIST;

Members

LayerIndex

The zero-based index of the overlay plane to display. The top plane (in the z-direction) has index zero. The planes' index values must be sequential from top to bottom.

Enabled

Indicates whether the overlay plane specified by LayerIndex is enabled for display.

hDeviceSpecificAllocation

A handle to the device-specific allocation that corresponds to the non device-specific allocation. The display miniport driver must set hDeviceSpecificAllocation to a handle value that it can use to refer to its private tracking structure for the allocation.

[in] SegmentId

The identifier of a segment that data is read from.

Reserved

This member is reserved and should be set to zero.

[in] PhysicalAddress

A PHYSICAL_ADDRESS data type (which is defined as LARGE_INTEGER) that indicates the physical address, within the segment that SegmentId specifies, where the data is read.
