D3D12_WRITEBUFFERIMMEDIATE_MODE enumeration (d3d12.h)

  • Article

Specifies the mode used by a WriteBufferImmediate operation.

Syntax

typedef enum D3D12_WRITEBUFFERIMMEDIATE_MODE {
  D3D12_WRITEBUFFERIMMEDIATE_MODE_DEFAULT = 0,
  D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_IN = 0x1,
  D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_OUT = 0x2
} ;

Constants

 
D3D12_WRITEBUFFERIMMEDIATE_MODE_DEFAULT
Value: 0
The write operation behaves the same as normal copy-write operations.
D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_IN
Value: 0x1
The write operation is guaranteed to occur after all preceding commands in the command stream have started, including previous WriteBufferImmediate operations.
D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_OUT
Value: 0x2
The write operation is deferred until all previous commands in the command stream have completed through the GPU pipeline, including previous WriteBufferImmediate operations. Write operations that specify D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_OUT don't block subsequent operations from starting. If there are no previous operations in the command stream, then the write operation behaves as if D3D12_WRITEBUFFERIMMEDIATE_MODE_MARKER_IN was specified.
