xv6 is a re-implementation of Unix Version 6 (v6), which was developed
|
|
|
|
|
by Dennis Ritchie and Ken Thompson. xv6 follows the structure and
|
|
|
|
|
style of v6, but is implemented for a modern x86-based multiprocessor
|
|
|
|
|
using ANSI C.
|
|
|
|
|
|
|
|
|
|
xv6 is inspired by the following work by Lions about Unix version 6:
