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

[Nigel Horne]

Public bug reported:

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.

[Nigel Horne]

I did a "git log" command, and the first line is
"2446333cd5b5c985f6517dee7004e542ecacd21c".  Is that what you mean by a
git hash?  If so, I hope it helps.

It looks like a firmware issue. Please report this to

I have done so, though to be honest I don't see that panic even if I use 
-nographic, QEMU still silently loops for me.

[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.

Also I can confirm that I have this problem on QEMU.
I had tried booting FreeBSD8.1-ppc under QEMU (Linux x86_64 host; PPC guest) 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 11/9/10.
The kernel starts OK then loops after "Kernel entry at 0x100100 ...".

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.

I used the -nographic option as well, but lost it in the copy and paste.

[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".

[Murilo Opsfelder Araújo]

Hi, Nigel.

Support for powerpc64 is available since FreeBSD 9.0-RELEASE, I think.
FreeBSD 11.2-RC2 boots fine in QEMU (at commit 46012db666990ff2eed1d3dc)
running on an x86 host with accel=tcg.  Below are the steps I have
followed to boot it.

Build QEMU:

$ mkdir build && cd build
$ ../configure --target-list=ppc64-softmmu
$ make -j$(nproc)

Boot FreeBSD:

$ wget http://ftp.freebsd.org/pub/FreeBSD/releases/powerpc/powerpc64/ISO-IMAGES/11.2/FreeBSD-11.2-RC2-powerpc-powerpc64-disc1.iso
$ ./qemu-img create -f qcow2 freebsd.qcow2 10G
$ ./ppc64-softmmu/qemu-system-ppc64 -name freebsd -machine pseries,accel=tcg,usb=off -m 1024 -realtime mlock=off -smp 4,sockets=4,cores=1,threads=1 -nographic -no-user-config -nodefaults -rtc base=utc -no-shutdown -boot strict=on -device pci-bridge,chassis_nr=1,id=pci.1,bus=pci.0,addr=0x1 -device pci-ohci,id=usb,bus=pci.0,addr=0x2 -device spapr-vscsi,id=scsi0,reg=0x2000 -drive file=freebsd.qcow2,format=qcow2,if=none,id=drive-scsi0-0-0-0 -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=1 -drive file=FreeBSD-11.2-RC2-powerpc-powerpc64-disc1.iso,format=raw,if=none,id=drive-scsi0-0-1-0,readonly=on -device scsi-cd,bus=scsi0.0,channel=0,scsi-id=1,lun=0,drive=drive-scsi0-0-1-0,id=scsi0-0-1-0,bootindex=2 -netdev user,id=hostnet0 -device spapr-vlan,netdev=hostnet0,id=net0,mac=4c:45:42:45:01:18,reg=0x1000 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 -msg timestamp=on -serial mon:stdio

Since this bug is almost 8 years old and FreeBSD powerpc64 seems to be
working just fine, I will close it.  Feel free to submit a new one if
needed.

Cheers
Murilo
