D3D12DDI_RESOURCE_RANGED_BARRIER_0022 structure

Description

Describes a resource ranged barrier.

Members

`hResource`

The handle of a resource. A null value means that the entire GPU cache must be flushed or invalidated. A non-null value means that the flush or invalidate action affects a smaller subset of the cache that can contain data for that resource.

`Subresource`

A subresource. If the Subresource value is -1 or _ALL_SUBRESOURCES, then a flush or invalidate action need only affect the part of the cache where the entire hResource may reside. If Subresource is not _ALL_SUBRESOURCES, a valid subresource index is specified and the Range may further constrain the impact of the operation.

`Range`

A range as a D3D12DDI_RANGE structure. If the resource is a texture with an adapter-dependent layout, the range must be (0, UINT64_MAX), because only the driver knows where a particular subresource resides. When the resource is a buffer or texture with well-specified layout, the range fits within the subresource extent. Empty ranges are never passed.
