DXGKCB_NOTIFY_MPO_VSYNC_FLAGS structure

Description

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

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.
