| 1 xv6 is a re-implementation of Dennis Ritchie's and Ken Thompson's Unix | |
| 2 Version 6 (v6). xv6 loosely follows the structure and style of v6, | |
| 3 but is implemented for a modern x86-based multiprocessor using ANSI C. | |
| 4 | |
| 5 ACKNOWLEDGMENTS | |
| 6 | |
| 7 xv6 is inspired by John Lions's Commentary on UNIX 6th Edition (Peer | |
| 8 to Peer Communications; ISBN: 1-57398-013-7; 1st edition (June 14, | |
| 9 2000)). See also http://pdos.csail.mit.edu/6.828/2012/v6.html, which | |
| 10 provides pointers to on-line resources for v6. | |
| 11 | |
| 12 xv6 borrows code from the following sources: | |
| 13 JOS (asm.h, elf.h, mmu.h, bootasm.S, ide.c, console.c, and others) | |
| 14 Plan 9 (entryother.S, mp.h, mp.c, lapic.c) | |
| 15 FreeBSD (ioapic.c) | |
| 16 NetBSD (console.c) | |
| 17 | |

| 36 BUILDING AND RUNNING XV6 | |
| 37 | |
| 38 To build xv6 on an x86 ELF machine (like Linux or FreeBSD), run "make". | |
| 39 On non-x86 or non-ELF machines (like OS X, even on x86), you will | |
| 40 need to install a cross-compiler gcc suite capable of producing x86 ELF | |
| 41 binaries. See http://pdos.csail.mit.edu/6.828/2012/tools.html. | |
| 42 Then run "make TOOLPREFIX=i386-jos-elf-". | |
| 43 | |
| 44 To run xv6, you can use the Bochs or QEMU PC simulators. Bochs makes | |
| 45 debugging easier, but QEMU is much faster. To run in Bochs, run "make | |
| 46 bochs" and then type "c" at the bochs prompt. To run in QEMU, run | |
| 47 "make qemu". | |
| 48 | |
| 49 To create a typeset version of the code, run "make xv6.pdf". This | |
| 50 requires the "mpage" utility. See http://www.mesa.nl/pub/mpage/. |
