Windows Driver Kit DDI reference (ns-d3dkmddi-dxgkargcb_feature_nativefence_caps_1)

Description

The DXGKARGCB_FEATURE_NATIVEFENCE_CAPS_1 structure describes the native fence capabilities of the OS.

Members

`SupportOptimizedDefaultFenceType`

Indicates whether the OS supports D3DDDI_NATIVEFENCE_TYPE_DEFAULT as described in Native GPU fence objects. If the OS sets this as TRUE, the OS supports allocating native fence storage in VRAM. KMD should query this OS cap and determine whether the OS allows KMD to specify a local memory SupportedSegmentSet during the creation of fence type D3DDDI_NATIVEFENCE_TYPE_DEFAULT.

`SupportIntraGpuFenceType`

Indicates whether the OS supports D3DDDI_NATIVEFENCE_TYPE_INTRA_GPU as described in Native GPU fence objects.

Remarks

For a sample code snippet and more information about native GPU fences, see Native GPU fence objects.
