Windows Driver Kit DDI reference (ne-d3d12umddi-d3d12ddi_node_io_flags_0108)

Description

The D3D12DDI_NODE_IO_FLAGS_0108 enumeration specifies flags used to describe the I/O behavior of a node in a work graph.

Constants

`D3D12DDI_NODE_IO_FLAG_INPUT`

The node is designed to receive input data.

`D3D12DDI_NODE_IO_FLAG_OUTPUT`

The node produces output data.

`D3D12DDI_NODE_IO_FLAG_READ_WRITE`

The node can be read from and written to.

`D3D12DDI_NODE_IO_FLAG_EMPTY_RECORD`

The node has an empty record.

`D3D12DDI_NODE_IO_FLAG_NODE_ARRAY`

The node is a part of an array of nodes.

`D3D12DDI_NODE_IO_FLAG_THREAD_RECORD`

The node is a thread record.

`D3D12DDI_NODE_IO_FLAG_GROUP_RECORD`

The node is a group record.

`D3D12DDI_NODE_IO_FLAG_DISPATCH_RECORD`

The node is a dispatch record.

`D3D12DDI_NODE_IO_FLAG_RECORD_GRANULARITY_MASK`

A mask that can be used to extract the record granularity from the flags.

`D3D12DDI_NODE_IO_FLAG_KIND_MASK`

A mask that can be used to extract the node's I/O kind from the flags.

`D3D12DDI_NODE_IO_FLAG_TRACK_RW_INPUT_SHARING`

The node tracks read-write input sharing.

`D3D12DDI_NODE_IO_FLAG_NODE_FLAGS_MASK`

A mask for extracting node-specific flags.

`D3D12DDI_NODE_IO_FLAG_RECORD_FLAGS_MASK`

A mask for extracting flags related to the node's record behavior.

Remarks

These flags are a DDI copy of the flags in NodeIOFlags and NodeIOKind encoding in DXIL metadata.
