Hello,

and run with :
qemu-system-ppc64 -M pseries -cpu POWER5+ -m 1G -smp 2 -kernel ./vmlinux -append
"root=/dev/sda" -drive file=./rootfs.ext2,if=scsi,index=0,format=raw -device
spapr-vlan,netdev=net0 -netdev user,id=net0 -serial mon:stdio -nographic -nodefaults
CPU 970, 970MP are also well supported.
Virtio devices and USB should be avoided because SLOF would use a
'stdbrx' instruction (cpu_to_le64 helper) which is invalid under
POWER5+ and 970 CPUs. SLOF needs to be compiled with -mcpu=power5 to
fix this issue.
Thanks,
C.
