README

        
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.

The following people have made contributions: Russ Cox (context switching,

locking), Cliff Frey (MP), Xiao Yu (MP), Nickolai Zeldovich, and Austin

Clements.

ERROR REPORTS

Please send errors and suggestions to Frans Kaashoek and Robert Morris

(kaashoek,[email protected]).  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".
