D3D12_FEATURE_DATA_QUERY_META_COMMAND structure (d3d12.h)

Indicates the level of support that the adapter provides for metacommands.

Syntax

typedef struct D3D12_FEATURE_DATA_QUERY_META_COMMAND {
  GUID       CommandId;
  UINT       NodeMask;
  const void *pQueryInputData;
  SIZE_T     QueryInputDataSizeInBytes;
  void       *pQueryOutputData;
  SIZE_T     QueryOutputDataSizeInBytes;
} D3D12_FEATURE_DATA_QUERY_META_COMMAND;

Members

CommandId

Type: GUID

The fixed GUID that identifies the metacommand to query about.

NodeMask

Type: UINT

For single GPU operation, this is zero. If there are multiple GPU nodes, a bit is set to identify a node (the device's physical adapter). Each bit in the mask corresponds to a single node. Only 1 bit must be set. Refer to Multi-adapter systems.

pQueryInputData

Type: const void*

A pointer to a buffer containing the query input data. Allocate QueryInputDataSizeInBytes bytes.

QueryInputDataSizeInBytes

Type: SIZE_T

The size of the buffer pointed to by pQueryInputData, in bytes.

pQueryOutputData

Type: void*

A pointer to a buffer containing the query output data.

QueryOutputDataSizeInBytes

Type: SIZE_T

The size of the buffer pointed to by pQueryOutputData, in bytes.
