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

[T. Huth]

Nigel, looking at https://www.freebsd.org/platforms/ppc.html it seems
like FreeBSD does not support the pseries machines yet, only some
flavours of PowerMac machines. So you should either use the "qemu-
system-ppc" binary (without the "64" suffix), or you've got to specify
one of the Mac machines, i.e. either "-M g3beige" or "-M mac99".

Title:
  PPC emulation loops on booting a FreeBSD kernel

Status in QEMU:
  New

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.
