D3DKMT_OFFER_PRIORITY enumeration

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

Syntax


typedef enum _D3DKMT_OFFER_PRIORITY { 
  D3DKMT_OFFER_PRIORITY_LOW     = 1,
  D3DKMT_OFFER_PRIORITY_NORMAL  = 2,
  D3DKMT_OFFER_PRIORITY_HIGH    = 3,
  D3DKMT_OFFER_PRIORITY_AUTO    = 4
} D3DKMT_OFFER_PRIORITY;

Constants

D3DKMT_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.

D3DKMT_OFFER_PRIORITY_NORMAL

The allocation has useful content but can easily be regenerated.

D3DKMT_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.

D3DKMT_OFFER_PRIORITY_AUTO

The video memory manager should make a policy decision on the allocation's value based on its priority for eviction.
