Description

This repository contains the code for the project of the course Operating Systems 2024 at USI.

The git repository is inside the pintos-env folder.

The .gitignore file is set to ignore every file, except the ones edided by us. This is done to avoid uploading the whole pintos environment, and to be able to keep track of the changes we made to the original system.

All the files not present in the repository are kept as the original ones.
