D3DDDI_MAKERESIDENT_FLAGS structure (d3dukmdt.h)

  • Article

D3DDDI_MAKERESIDENT_FLAGS is used with MakeResident (pfnMakeResidentCb or D3DKMTMakeResident) to instruct the OS to add a resource to the device residency list and increment the residency reference count on this allocation.

Syntax

typedef struct D3DDDI_MAKERESIDENT_FLAGS {
  union {
    struct {
      UINT CantTrimFurther : 1;
      UINT MustSucceed : 1;
      UINT Reserved : 30;
    };
    UINT Value;
  };
} D3DDDI_MAKERESIDENT_FLAGS;

Members

CantTrimFurther

This flag should be used after the user mode driver has trimmed all other possible resources in the device and require the current resource to be made resident in order to make forward progress on a particular single atomic operation.

MustSucceed

This flag may only be set if CantTrimFurther is also set. It indicates that the resource being made resident is critical to the device forward progress. If the video memory manager can’t satisfy the request the device will be put in error.

Reserved

This member is reserved and should be set to zero.

Value

The consolidated value of the structure.
