[Qemu-devel] [PATCH 00/17] PPC: Mac OS X guest bringup v2

[Alexander Graf]

Recently there has been a lot of progress on the OpenBIOS side to get Mac OS X
to boot.

For a while now it seemed there was only very little to make it a fully working
guest os in QEMU.

This patch set is the result of this. With this I can successfully boot Mac OS X
10.2 to 10.4 with the g3beige machine all the way to the GUI. I was not able to
boot 10.0 or 10.1, both of which crashed in interrupt controller registration.
10.5 does not include drivers for g3beige anymore. Everything as of 10.6 is x86
only.

The mac99 target doesn't look quite as good, but also very close. FWIW only
minor issues in our NVRAM layout keep us from using that one. 10.4 already
boots for me.

Please don't try to run this with KVM yet. Mac OS X uses mixed mode (half real,
half paged) extensively, which happens to break badly in KVM.

For reference, here are a few pictures:

If you want to try this out, please apply the patches on top of my ppc-next
queue. Or just use this git repo:
