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".
