D3DKMT_CROSSADAPTERRESOURCE_SUPPORT structure (d3dkmthk.h)

  • Artikel

Currently reserved for system use. The D3DKMT_CROSSADAPTERRESOURCE_SUPPORT structure indicates the cross adapter resource support provided by a display driver.

Syntax

typedef struct _D3DKMT_CROSSADAPTERRESOURCE_SUPPORT {
  D3DKMT_CROSSADAPTERRESOURCE_SUPPORT_TIER SupportTier;
} D3DKMT_CROSSADAPTERRESOURCE_SUPPORT;

Members

SupportTier

A D3DKMT_CROSSADAPTERRESOURCE_SUPPORT_TIER value that describes the tier(s) of support provided by the driver for cross-adapter resources.

Remarks

The tiers of support for cross-adapter resources are:

  • Copying to and from cross-adapter resources (tier 1)
  • Texturing from (tier 2)
  • Scan-out (tier 3)

Each higher tier of support must imply and guarantee the support tiers below it. For example, to claim support for scan-out of cross-adapter resources, the driver must also support texturing and copy, too (D3DKMT_CROSSADAPTERRESOURCE_SUPPORT_TIER_COPY && D3DKMT_CROSSADAPTERRESOURCE_SUPPORT_TIER_TEXTURE && D3DKMT_CROSSADAPTERRESOURCE_SUPPORT_TIER_SCANOUT).
