Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddi_global_barrier_0088)

Description

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.

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.
