DXGKCB_NOTIFY_INTERRUPT_DATA_FLAGS structure (d3dkmddi.h)
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.
Syntax
typedef struct _DXGKCB_NOTIFY_INTERRUPT_DATA_FLAGS {
union {
struct {
UINT ValidPhysicalAdapterMask : 1;
UINT HsyncFlipCompletion : 1;
UINT EvaluateLegacyMonitoredFences : 1;
#if ...
UINT Reserved : 29;
#else
UINT Reserved : 31;
#endif
};
UINT Value;
};
} DXGKCB_NOTIFY_INTERRUPT_DATA_FLAGS;
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.
