I use the following command, but it does nothing, it stays in uboot
prompt as when I don't get a kernel argument
~/qemu/build/qemu-system-ppc -M taihu -bios

arch/powerpc/boot/uImage
I'm not sure using -bios and -kernel together makes sense, it probably
starts u-boot in this case and you have to load and start the kernel
from u-boot as you'd notmally do on a real machine. Alternatively you
could use -kernel instead of -bios which then loads a kernel and starts
it directly but not sure if it needs a firmware to work.
Ot I could be completely wrong as I don't know this machine and haven't
tried it.
Usually -bios overwrites -kernel/-append cmdline options.
Having them accepted together is probably a configuration mistake,
and we should reject that (generically).
No, having -bios and -kernel together is perfectly fine if the BIOS knows
about it. Have a look at the ppc64 pseries machine, it works perfectly fine
with -bios and -kernel at the same time.
