DXGK_ALLOCATIONINFOFLAGS2 structure (d3dkmddi.h)

The DXGK_ALLOCATIONINFOFLAGS2 structure contains additional properties for an allocation.

Syntax

typedef struct _DXGK_ALLOCATIONINFOFLAGS2 {
  union {
    struct {
      UINT ShareBackingStoreWithKmd : 1;
      UINT NoImplicitSynchronization : 1;
      UINT DisablePartialResidency : 1;
      UINT RestrictedToSingleSegment : 1;
      UINT NeedPagingVaAtResidencyNotification : 1;
      UINT Reserved01 : 1;
      UINT FaultAndStall : 1;
#if ...
      UINT Reserved : 25;
#else
      UINT Reserved : 31;
#endif
    };
    UINT Value;
  };
} DXGK_ALLOCATIONINFOFLAGS2;

Members

ShareBackingStoreWithKmd

When set, the kernel-mode driver (KMD) is notifying Dxgkrnl that it needs to know the address of the allocation backing store. The allocation must be created shared and must reside only in the aperture memory segment.

NoImplicitSynchronization

When set, KMD is opting out of implicit primary synchronization. This flag was introduced in Windows 11, version 24H2 (WDDM 3.2).

DisablePartialResidency

When set, indicates that the allocation doesn't support partial residency. The allocation must either be entirely evicted or entirely resident. This flag was introduced in Windows 11, version 24H2 (WDDM 3.2).

RestrictedToSingleSegment

When set, indicates that the allocation doesn't support cross-segment residency. The allocation must be entirely resident within a single segment. This flag was introduced in Windows 11, version 24H2 (WDDM 3.2).

NeedPagingVaAtResidencyNotification

Reserved01

FaultAndStall

Reserved

Reserved; do not use.

Value

An alternative way to access the bits of this structure.
