README

A fork of xv6 with support for devcontainer.

# Installation
1. Clone the repository.
2. Install devcontainer dependencies https://code.visualstudio.com/docs/remote/containers#_installation.
    * Linux users might need to also do https://docs.docker.com/engine/install/linux-postinstall/.
3. Open vscode and select File -> open folder.
4. Select the cloned repository folder.
5. Press "Reopen in Container".
6. ???
7. Profit.

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.

ACKNOWLEDGMENTS

xv6 is inspired by John Lions's Commentary on UNIX 6th Edition (Peer
to Peer Communications; ISBN: 1-57398-013-7; 1st edition (June 14,
2000)).  See also https://pdos.csail.mit.edu/6.1810/, which provides
pointers to on-line resources for v6.

ERROR REPORTS

Please send errors and suggestions to Frans Kaashoek and Robert Morris
(kaashoek,rtm@mit.edu).  The main purpose of xv6 is as a teaching
operating system for MIT's 6.1810, so we are more interested in
simplifications and clarifications than new features.

BUILDING AND RUNNING XV6

You will need a RISC-V "newlib" tool chain from
https://github.com/riscv/riscv-gnu-toolchain, and qemu compiled for
riscv64-softmmu.  Once they are installed, and in your shell
search path, you can run "make qemu".
