D3D12DDI_GLOBAL_BARRIER_0088 structure (d3d12umddi.h)

Important

Some information relates to a prerelease product which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

The D3D12DDI_GLOBAL_BARRIER_0088 structure describes a resource memory access barrier. This barrier is used by global, texture, and buffer barriers to indicate when resource memory must be made visible for a specific access type.

Syntax

typedef struct D3D12DDI_GLOBAL_BARRIER_0088 {
  D3D12DDI_BARRIER_SYNC   SyncBefore;
  D3D12DDI_BARRIER_SYNC   SyncAfter;
  D3D12DDI_BARRIER_ACCESS AccessBefore;
  D3D12DDI_BARRIER_ACCESS AccessAfter;
} D3D12DDI_GLOBAL_BARRIER_0088;

Members

SyncBefore

A D3D12DDI_BARRIER_SYNC value that specifies the synchronization scope of all preceding GPU work that must be completed before executing the barrier.

SyncAfter

A D3D12DDI_BARRIER_SYNC value that specifies the synchronization scope of all subsequent GPU work that must wait until the barrier execution is finished.

AccessBefore

A D3D12DDI_BARRIER_ACCESS value that specifies the write accesses that must be flushed and finished before the barrier is executed.

AccessAfter

A D3D12DDI_BARRIER_ACCESS value that specifies the accesses that must be available for data written via AccessBefore after the barrier is executed.

Remarks

See Enhanced Barriers for general information.
