D3DDDI_OFFER_PRIORITY enumeration (d3dukmdt.h)

  • Article

Indicates the importance of video memory resources that the user-mode display driver offers for reuse.

Syntax

typedef enum _D3DDDI_OFFER_PRIORITY {
  D3DDDI_OFFER_PRIORITY_NONE,
  D3DDDI_OFFER_PRIORITY_LOW,
  D3DDDI_OFFER_PRIORITY_NORMAL,
  D3DDDI_OFFER_PRIORITY_HIGH,
  D3DDDI_OFFER_PRIORITY_AUTO
} D3DDDI_OFFER_PRIORITY;

Constants

 
D3DDDI_OFFER_PRIORITY_NONE
The allocation should not be offered.

Note  Do not use this value in the D3DDDICB_OFFERALLOCATIONS.Priority member.

 
D3DDDI_OFFER_PRIORITY_LOW
The allocation has low value and should be discarded before other offered allocations. Specify this type for allocations that have no useful content.
D3DDDI_OFFER_PRIORITY_NORMAL
The allocation has useful content but can easily be regenerated.
D3DDDI_OFFER_PRIORITY_HIGH
The allocation has useful content and cannot easily be regenerated. The video memory manager (which is part of Dxgkrnl.sys) should therefore avoid discarding this allocation before other offered allocations.
D3DDDI_OFFER_PRIORITY_AUTO
The video memory manager should make a policy decision on the allocation's value based on its priority for eviction.
