Detailed Description

This class is the architecture model for tofino devices. P4-16 architecture file exposes the user-configurable CSRs as intrinsic metadata to P4 programmers. Different generation of devies may have different set of CSRs, which is encapsulated in this class.

◆ getDeparserIntrinsicMetadataForDeparserParamIndex()

int ArchSpec::getDeparserIntrinsicMetadataForDeparserParamIndex ( ) const
inline

Get the index of the intrinsic metadata for deparser parameter in the deparser.

The parameter is the ingress_intrinsic_metadata_for_deparser_t or egress_intrinsic_metadata_for_deparser_t for the corresponding gress.

Returns
index of the intrinsic metadata for deparser parameter
