_DXGK_MULTIPLANEOVERLAYCAPS structure

Description

Multiplane overlay capabilities returned by the DxgkDdiGetMultiPlaneOverlayCaps function.

Members

Rotation

When TRUE, indicates that the hardware supports rotating the plane 90, 180, or 270 degrees.

If TRUE, RotationWithoutIndependentFlip should be FALSE.

RotationWithoutIndependentFlip

When TRUE, indicates that the driver can perform plane rotation of 90, 180, or 270 degrees, but IndependentFlip cannot be used when rotating the plane.

If TRUE, Rotation should be FALSE.

VerticalFlip

When TRUE, the hardware supports flipping the plane vertically.

HorizontalFlip

When TRUE, the hardware supports flipping the plane horizontally.

StretchRGB

When TRUE, the hardware supports stretching any plane containing RGB data.

StretchYUV

When TRUE, the hardware supports stretching any plane containing YUV data.

BilinearFilter

When TRUE, the hardware supports bilinear filtering.

HighFilter

When TRUE, the hardware supports better than bilinear filtering.

Shared

When TRUE, the multiplane overlay resources reported by the capabilities are shared across all VidPn sources.

When FALSE, the multiplane overlay resources reported by capabilities are dedicated to the specific VidPn source.

Immediate

When TRUE, the HW supports immediate flips of the MPO plane.

If the flip contains changes that cannot be performed as an immediate flip, the driver can promote the flip to a VSYNC flip using the new HSync completion infrastructure.

Plane0ForVirtualModeOnly

When TRUE, the hardware will always apply the stretch factor of plane 0 to the hardware cursor as well as the plane. This implies that stretching/shrinking of plane 0 should only occur when plane 0 is the desktop plane and when the stretching/shrinking is used for virtual mode support.

Reserved

This member is reserved and should be set to zero. Setting this member to zero is equivalent to setting the remaining 21 bits (0xFFFFFFFC) of the 32-bit Value member to zeros.

Value
