ASIC Config Generation

Introduction

This document gives a very brief overview of the ASIC config generation process.

ASIC Config Generation Workflow​

Asic Config Generation Tool​

We provide a script to help external FBOSS vendors generate their respective ASIC config contents.

Prerequisites​

Python 3 is required in order to run the helper script. You can install it via one of the below commands depending on which Linux distribution you're on.

Debian​
sudo apt update
sudo apt -y upgrade
sudo apt install python3
CentOS​
sudo dnf upgrade -y
sudo dnf install python3

Instructions​

Platform mapping config generation is done via running the helper script below from the root of the FBOSS repository. By default, this runs on all platforms which have configs specified in asic_config_v2/all_asic_config_params.py.

$ ./fboss/lib/asic_config_v2/run-helper.sh

You will need to add support for your specific platform in asic_config_v2/all_asic_config_params.py and asic_config_v2/gen.py.

Generating Agent Config from ASIC Config​

Once your ASIC config is generated in generated_asic_configs/, you can use our Agent Config Helper Script to create an agent config for testing.

Please follow the usage instructions in that file.
