D3D12_BUFFER_BARRIER structure (d3d12.h)

  • Article

Describes a buffer memory access barrier. Used by buffer barriers to indicate when resource memory must be made visible for a specific access type.

Syntax

typedef struct D3D12_BUFFER_BARRIER {
  D3D12_BARRIER_SYNC   SyncBefore;
  D3D12_BARRIER_SYNC   SyncAfter;
  D3D12_BARRIER_ACCESS AccessBefore;
  D3D12_BARRIER_ACCESS AccessAfter;
  ID3D12Resource       *pResource;
  UINT64               Offset;
  UINT64               Size;
} D3D12_BUFFER_BARRIER;

Members

SyncBefore

Synchronization scope of all preceding GPU work that must be completed before executing the barrier.

SyncAfter

Synchronization scope of all subsequent GPU work that must wait until the barrier execution is finished.

AccessBefore

Access bits corresponding with resource usage since the preceding barrier, or the start of ExecuteCommandLists scope.

AccessAfter

Access bits corresponding with resource usage after the barrier completes.

pResource

Pointer to the buffer resource being using the barrier.

Offset

Must be 0.

Size

Must be either UINT64_MAX or the size of the buffer in bytes.
