[Qemu-devel] [Bug 623852] Re: PPC emulation loops on booting a FreeBSD kernel

[Nigel Horne]

Please confirm that you tested with qemu-system-ppc, not qemu-system-
ppc64.

I got the "above 32-bit boundary" message with ppc64 - but that's to be
expected.  And given that I didn't see your message running 32-bit PPC I
want to ensure that you did try with the 32-bit emulator.

Bug description:
Has anyone tried booting FreeBSD8.1-ppc under QEMU (Linux x86_64 host; PPC 
guest)?  I can get Linux/PPC to run fine, and FreeBSD8.1-i386 as well; but 
there seems to be a problem with whatever the FreeBSD8.1 kernel does, that 
QEMU's PPC emulation can't handle.

I am using the latest version of QEMU from GIT as of 25/8/10.  I don't know how 
to get a "git commit hash", so I can't quote it.

The kernel starts OK then loops after "Kernel entry at 0x100100 ...".

The command I am running is

qemu-system-ppc -cdrom FreeBSD-8.1-RELEASE-powerpc-disc1.iso -hda 
freebsd8.1-ppc -m 94 -boot d"

I obtained the kernel from 
ftp://ftp.freebsd.org/pub/FreeBSD/releases/powerpc/ISO-IMAGES/8.1/FreeBSD-8.1-RELEASE-powerpc-disc1.iso.
