I've been playing with qemu svn again recently, preparing experimental
FreeBSD ports (see
http://docs.freebsd.org/cgi/mid.cgi?20080620211216.GA75382
for the details), and want to note a few things:
- The snapshot script for
http://qemu-forum.ipi.fi/qemu-snapshots/
apparently still checks out from cvs, which means qemu svn surely gets
less testing than it could. :) Anyway I had to make my own tarball for
the port to get (using svn export), available at:
http://people.fruitsalad.org/nox/qemu/qemu-snapshot-2008-06-20_19.tar.bz2
- kqemu-1.4.0pre1 seems to also work on FreeBSD (I only had to add
KQEMU_SET_PHYS_MEM handling to the existing patches from the FreeBSD
kqemu-kmod port; if you've been following the FreeBSD side of things you
know that it finally no longer crashes/hangs the host on amd64 SMP there...
The patches can be seen here:
http://www.freebsd.org/cgi/cvsweb.cgi/ports/emulators/kqemu-kmod/files/
)
- I also needed to patch exec.c:code_gen_alloc() for amd64:

(gdb) q
(Memory corruption, right?) I've put the end of a in_asm,out_asm log up at
http://people.freebsd.org/~nox/qemu/tcgbug-i386host.log.txt
(its long.) That function is MD5Transform() in:
http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/kern/md5c.c?annotate=1.27
in the FreeBSD 7.0 amd64 kernel on
ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/7.0/7.0-RELEASE-amd64-livefs.iso
(the bootonly most likely will fail in the same way:
ftp://ftp.freebsd.org/pub/FreeBSD/ISO-IMAGES-amd64/7.0/7.0-RELEASE-amd64-bootonly.iso
, you can go to
http://mirrorlist.freebsd.org/
to find a mirror near you, search for ISOs.)
Okay I guess thats for now, and thanx to everyone involved!
