Windows Driver Kit DDI reference (ns-d3dkmddi-_dxgk_multiplane_overlay_plane)

_DXGK_MULTIPLANE_OVERLAY_PLANE structure

[!NOTE] This structure has been replaced by DXGK_MULTIPLANE_OVERLAY_PLANE3.

Description

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

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.

If FALSE, the display miniport driver should disable the specified overlay plane.

If a plane was enabled during a previous call to DxgkDdiSetVidPnSourceAddressWithMultiPlaneOverlay, the driver should continue to display the plane without flipping it.

AllocationSegment [in]

The identifier of a segment that data is read from.

AllocationAddress [in]

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

hAllocation

A handle to the allocation to be displayed on the overlay plane.

PlaneAttributes

A structure of type DXGK_MULTIPLANE_OVERLAY_ATTRIBUTES that specifies overlay plane attributes.
