About

This repository is for first phase of the "Operating System" course project at Amirkabir University of Technology in Fall 2022

The project has 3 phases:

_⤷ _phase1

_⤷ _phase2

_⤷ _phase3

Overview

XV6 is a simple Unix-like teaching operating system that serves as a reference to better understand the concepts of operating systems.

In this phase, we have extended the xv6 operating system to support thread

Implemented features

• Add thread implementation to the xv6 operating system and the 3 following system calls to support it:

  1. The thread_create system call allows the user to create a new thread which uses the same address space as its parent.

  2. The thread_id system call returns the tid (thread id) of the new thread.

  3. The thread_join system call makes the thread's parent wait for it until it finishes its job.

  The functionality of these parts can be tested using threadTest command.
