Qemu doesn't emulate cycle-accurately. Instead, it converts guest code to host code and executes it as fast as it can. So whatever you tell the guest on the cpu speed doesn't really matter. Except for the timebase of course :). Mind if I ask what exactly you're trying to do with ppc emulation? I'm interested in use cases people have. Alex > Tai
