D3D12DDI_RANGED_BARRIER_0094 structure (d3d12umddi.h)

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

Syntax

typedef struct D3D12DDI_RANGED_BARRIER_0094 {
  D3D12DDI_RANGED_BARRIER_FLAGS_0094 Flags;
  D3D12DDI_HRESOURCE                 hResource;
  UINT                               Subresource;
  D3D12DDI_RANGE                     Range;
} D3D12DDI_RANGED_BARRIER_0094;

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.
