[Qemu-devel] [PATCH 00/11] PPC64 Linux bringup patches v3

[Alexander Graf <agraf@suse.de>]

After spending even more time trying to get qemu-system-ppc64 to run Linux, I
get up to userspace now :-).

I am aware that this patchset is not 100% accurate and perfect for emulation,
but I think that it can't get worse than it is now.

This patchset enhances MMU support to work with large pages, implement tlbiel,
and fixes random issues I ran into while getting closer to the kernel running
userspace code :).

Keep in mind that this also requires an OpenBIOS update, as the current code
is not aware that it gets run in 64 bit mode.

For now booting into userspace from an initrd works fine. I didn't try to get
IDE working, but it looks like that's broken. Also console=ttyPZ0 doesn't work
for me, because the pmz doesn't initialize properly (probably an OpenBIOS issue).

So as long as you use graphical mode and run code from an initrd, you're fine.

I also removed the lwsync patch from this patchset, as it only fixed symptoms
and no causes. It would be great if anyone would step up to find out how to
fix that, as it's not a ppc-only problem.
