Just for some motivation, this is what we want to make possible for more people with QEMU 8.0: https://youtu.be/YY9RExl4VDI

This would need at least my SM502 patches and fixing the IRQ routing in the VT8231 (this test was with my series for that, I'll ask testing Bernhard's version the same way once I get it and rebase my patches on it). AmigaOS can use ES1370 so the via-ac97 patches are not that important now but the other patches would be needed. I hope users won't have to wait until September to try this.

While AmigaOS runs on sam460ex now, that versiion is much slower due to the limited PPC440 that doesn't have AltiVec and also due to some issues on the real platform it has to do more synchronisation which slows it down. The pegasos2 version runs much better and has a better chance to get it to work with KVM on PPC host so this would be a big improvement even if there would be more bugs to fix in upcoming releases but we'll never find those unless people can start using it and report them. More people are interested but less are able to compile and test from git repos and depend on binary distros instead.
