In an effort to get KVM on PPC more useful for other userspace users than Qemu, I figured it'd be a nice idea to implement virtualization of the Gekko CPU. The Gekko is the CPU used in the GameCube. In a slightly more modern fashion it lives on in the Wii today. Using this patch set and a modified version of Dolphin, I was able to virtualize simple GameCube demos on a 970MP system. As always, while getting this to run I stumbled across several broken parts and fixed them as they came up. So expect some bug fixes in this patch set too.
