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.
Contents
Purpose[edit]
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[edit]
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 99 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[edit]
xv6 has also been used in operating systems courses at Southern Adventist University,[3] University of Illinois at Chicago,[4] Rutgers University,[5] Northeastern University,[6] Yale University,[7] Columbia University,[8] Ben-Gurion University,[9] Johns Hopkins University,[10] Portland State University,[11] Tsinghua University,[12] the University of Wisconsin-Madison,[13] Binghamton University, the University of Utah,[14] [15] University of California, Riverside,[16] IIT Bombay, IIT Madras and IIT Bhubaneswar in India, the Linnaeus University[17] in Sweden, the University of Otago[18] in New Zealand, the National University of Córdoba[19] and the National University of Río Cuarto,[20] in Argentina, the Università degli Studi di Palermo[21] and Università degli Studi di Modena e Reggio Emilia[22] in Italy and the Federal University of Minas Gerais[23] in Brazil.
Production Use[edit]
- TrustKernel's T6[24] secure kernel is an Xv6 ARM ported OS and has been deployed into many secure phones in China.
