Xv6 is a pretty good material for OS learners, but one thing I am concerned is that how I benchmark xv6 after I developed or changed it. For example, xv6 has really simple scheduling algorithm that we easily understand, so that it may be a good idea to develop scheduling algorithm to improve xv6 performance. However, one problem I met was how should I benchmark it? Therefore, I have modified 'hackbench.c', one of the simple benchmarking program, and now it can run on xv6. So, if you need to benchmark your implementations like me, you can download and measure your system on xv6.

README

        
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)

The following people made contributions:

    Russ Cox (context switching, locking)

    Cliff Frey (MP)

    Xiao Yu (MP)

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".  Both log the xv6 screen output to 

standard output.

To create a typeset version of the code, run "make xv6.pdf".

This requires the "mpage" text formatting utility.
