DXGKCB_NOTIFY_INTERRUPT_DATA_FLAGS structure

Description

The DXGKCB_NOTIFY_INTERRUPT_DATA_FLAGS structure indicates whether the display miniport driver provides a physical adapter mask in a call to the DXGKCB_NOTIFY_INTERRUPT function.

Members

`ValidPhysicalAdapterMask`

Specifies whether the driver provides a physical adapter mask. If this member is set, the driver provides a physical adapter mask in the PhysicalAdapterMask member of the CrtcVsync structure that is contained in the DXGKARGCB_NOTIFY_INTERRUPT_DATA structure.

Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

`HsyncFlipCompletion`

Specifies whether the Hsync flip has been completed.

`EvaluateLegacyMonitoredFences`

When set, indicates to the OS to scan all waiters (legacy monitored fence waiter & native fence waiters). For more information, see Native GPU fence objects. Available starting with Windows 11, version 22H2 (WDDM 3.2).

`Reserved`

This member is reserved and should be set to zero.

`Value`

An alternative way to access to bit fields of this structure.
