We need quite a bunch of new constants for PPC64, so let's define
them now.
These constants will be used in later patches.

This adds the 970 specific header file that contains structs that
are only valid on 970 specific code.

I haven't implemented dirty logging yet, but without things are just way too
slow. So for the time being I hacked in a dummy function that always tells
userspace we're dirty in VGA regions.
Please don't apply this. This patch is for reference only.

KVM on BookE always virtualizes the host CPU. On PPC64 we go a step further
and take the PVR from userspace that tells us what kind of CPU we are supposed

We need to store more information than we currently have for vcpus
when running on PPC64.
So let's extend the internal struct definitions.

KVM for PowerPC only supports embedded cores at the moment.
While it makes sense to virtualize on small machines, it's even more fun
to do so on big boxes. So I figured we need KVM for PowerPC64 as well.
This patchset implements KVM support for

From a quick review (not that I'm qualified to review ppc code) this
looks very good.
Wow - thanks :-).
Well, I only reviewed the code that I understood, which was the
whitespace. Apparently that part is a well-formed program (see

We already have tophys() for that in ppc_asm.h

Getting from host state to the guest is only half the story. We also need

the guest.
On PowerPC every guest exit is an interrupt. So all we need to do is trap
