xv6 is a modern reimplementation of Sixth Edition Unix in ANSI C for multiprocessor x86 systems. It is used for pedagogical purposes in MIT's Operating Systems Engineering (6.828) course.

Purpose

Unlike Linux or BSD, xv6 is simple enough to cover in a semester, yet still contains the important concepts and organization of Unix.[1] Rather than study the original V6 code, the course uses xv6 since PDP-11 machines are not widely available and the original operating system was written in archaic pre-ANSI C.[1]

Self-documentation

One feature of the Makefile for xv6 is the option to produce a PDF of the entire source code listing in a readable format. The entire printout is only 97 pages, including cross references.[2] This is reminiscent of the original V6 source code, which was published in a similar form in Lions' Commentary on UNIX 6th Edition, with Source Code.

Educational use

xv6 has also been used in operating systems courses at University of Illinois at Chicago,[3] Rutgers University,[4] Northeastern University,[5] Yale University,[6] Columbia University,[7] Ben-Gurion University,[8] Johns Hopkins University,[9] Tsinghua University,[10] the University of Wisconsin-Madison,[11] the University of Utah,[12] [13] IIT Madras in India, the Linnaeus University[14] in Sweden, the University of Otago[15] in New Zealand, the National University of Córdoba[16] and the National University of Río Cuarto,[17] in Argentina, the Università degli Studi di Palermo[18] in Italy and the Federal University of Minas Gerais[19] in Brazil.
