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 x86-based 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 http://pdos.csail.mit.edu/6.828/2007/v6.html, which
provides pointers to on-line resources for v6.
xv6 borrows code from the following sources:
JOS (asm.h, elf.h, mmu.h, bootasm.S, ide.c, console.c, and others)
Plan 9 (bootother.S, mp.h, mp.c, lapic.c)
FreeBSD (ioapic.c)
NetBSD (console.c)

In addition, we are grateful for the patches contributed by Greg
Price, Yandong Mao, and Hitoshi Mitake.

ERROR REPORTS
If you spot errors or have suggestions for improvement, please send
email to Frans Kaashoek and Robert Morris (kaashoek,rtm@csail.mit.edu).
BUILDING AND RUNNING XV6
To build xv6 on an x86 ELF machine (like Linux or FreeBSD), run "make".
On non-x86 or non-ELF machines (like OS X, even on x86), you will
need to install a cross-compiler gcc suite capable of producing x86 ELF
binaries. See http://pdos.csail.mit.edu/6.828/2007/tools.html.
Then run "make TOOLPREFIX=i386-jos-elf-".
To run xv6, you can use Bochs or QEMU, both PC simulators.
Bochs makes debugging easier, but QEMU is much faster.
To run in Bochs, run "make bochs" and then type "c" at the bochs prompt.
To run in QEMU, run "make qemu".
To create a typeset version of the code, run "make xv6.pdf". This
requires the "mpage" utility. See http://www.mesa.nl/pub/mpage/.
