Detailed Description

Class for generating resources.json logfile.

It uses API autogenerated from resources_schema.py, you can find it by running make and then searching for resources_schema.h in the build dir. The classes have the same names as in schema and they have the same nested structure. Dictionaries also become classes.

All properties that are not an array must be initialized in the constructor and parameters are always sorted alphabetically.

Enums will become strings/ints and optional ints/optional int enums will be int pointers (int pointer with nullptr value will not be emitted).

Member Typedef Documentation

◆ ExactMatchResultBusResourceUsage

using BFN::ResourcesLogging::ExactMatchResultBusResourceUsage

Initial value:

Resources_Schema_Logger::ExactMatchResultBusResourceUsage

◆ ExactMatchSearchBusResourceUsage

using BFN::ResourcesLogging::ExactMatchSearchBusResourceUsage

Initial value:

Resources_Schema_Logger::ExactMatchSearchBusResourceUsage

Member Function Documentation

◆ end_apply()

void BFN::ResourcesLogging::end_apply ( const IR::Node * root )

overrideprotectedvirtual

Performs actual logging - aggregates all collected data and stores them in the json file. Also updates manifest so it knows where to find that file.

Reimplemented from P4::Visitor.

◆ preorder() [1/2]

bool BFN::ResourcesLogging::preorder ( const IR::BFN::Pipe * p )

overrideprotected

Prepares the object and collects data for parser and clot usage.

◆ preorder() [2/2]

bool BFN::ResourcesLogging::preorder ( const IR::MAU::Table * tbl )

overrideprotected

Collects data for this particular table resource usage and stores it into stageResources.
