Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddi_ranged_barrier_0094)

Description

The D3D12DDI_RANGED_BARRIER_0094 structure describes a resource ranged barrier. This structure replaces the legacy D3D12DDI_RESOURCE_RANGED_BARRIER_0022 structure.

Members

`Flags`

A D3D12DDI_RANGED_BARRIER_FLAGS_0094 value that specifies flags for the ranged barrier.

`hResource`

The handle of the resource using the barrier. 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 D3D12DDI_BARRIER_SUBRESOURCE_RANGE_0088 structure that specifies the range of subresources being barriered.

`Range`

A D3D12DDI_RANGE structure that describes a memory range.

Remarks

Enhanced barriers fully deprecate the legacy ResourceBarrier DDIs. This includes the ranged barriers used internally by AtomicCopy commands.

See Enhanced Barriers for general information.
