Constants
D3D12DDI_NODE_IO_FLAG_INPUTThe node is designed to receive input data. |
D3D12DDI_NODE_IO_FLAG_OUTPUTThe node produces output data. |
D3D12DDI_NODE_IO_FLAG_READ_WRITEThe node can be read from and written to. |
D3D12DDI_NODE_IO_FLAG_EMPTY_RECORDThe node has an empty record. |
D3D12DDI_NODE_IO_FLAG_NODE_ARRAYThe node is a part of an array of nodes. |
D3D12DDI_NODE_IO_FLAG_THREAD_RECORDThe node is a thread record. |
D3D12DDI_NODE_IO_FLAG_GROUP_RECORDThe node is a group record. |
D3D12DDI_NODE_IO_FLAG_DISPATCH_RECORDThe node is a dispatch record. |
D3D12DDI_NODE_IO_FLAG_RECORD_GRANULARITY_MASKA mask that can be used to extract the record granularity from the flags. |
D3D12DDI_NODE_IO_FLAG_KIND_MASKA mask that can be used to extract the node's I/O kind from the flags. |
D3D12DDI_NODE_IO_FLAG_TRACK_RW_INPUT_SHARINGThe node tracks read-write input sharing. |
D3D12DDI_NODE_IO_FLAG_NODE_FLAGS_MASKA mask for extracting node-specific flags. |
D3D12DDI_NODE_IO_FLAG_RECORD_FLAGS_MASKA 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.
