[OpenBIOS] Ppc guest debugging?

[Jd Lyons]

I need to try and debug the macOS trampoline inits during the early boot process of OS 9. I’m thinking Qemu supports this, but I’m unsure how to set it up?

I installed gdb-multiarch and started qemu with:

Qemu-system-ppc -s -S

The launched gdb-multiarch and connected  to port 1234.

Is this the correct toolchain for debugging PPC code on an X86 host, or do I need to do something else?
