qin-you / xv6-labs

labs on an unix-like operating system while learning MIT OS course 6.S081

xv6 is a re-implementation of Dennis Ritchie's and Ken Thompson's Unix Version 6 (v6). xv6 loosely follows the structure and style of v6, but is implemented for a modern RISC-V multiprocessor using ANSI C.

I learned this course 6.S081 by myself in 2023/7. This repo records my learning process. The most difficult labs for me are file system and mmap. You can see the according solution code with:

git checkout fs
git checkout mmap

The origin source code of xv6 without lab-solution code can be got with:

git clone git://g.csail.mit.edu/xv6-labs-2021

Note that everytime when finish a lab, you need to checkout to another new branch. The command git branch is helpful to list all local branchs.

The course's Schedule table can be found here.

This is the best course of OS I've ever seen! Spending a continuous period of time to learn this course is very suggested.

Enjoy!
