It's a matter of perspective. :)
The PowerPC architecture has no IO instructions; therefore all IO
accesses are MMIO.
However, you can place devices with IO ports in a PowerPC system. In
this case, the bridges are configured to translate MMIO accesses coming
from the processor into IO port

Hi, Avi
This series of patches are introduced to split qemu-kvm.c, and make it
arch-independent.
In these patches, one file called qemu-kvm-x86.c is created. For
arch-specific stuff, I also use kvm_arch prefix to hold arch-specific
code.
Tested on x86 and x86_64
The current irq and exception injection infrastructure is quite complex and
has been the source of a number of bugs in the past. This patchset simplifies
irq and exception injection:

Instead of each subarch doing its own thing, add an API for queuing an
injection, and manage failed exception injection centerally (i.e., if
an inject failed due to a shadow page fault, we need to requeue it).

This moves the tpr shadow processing into the local apic code from the vmx
interrupt injection path. This will allow decoupling the irq injection path
from normal execution (which needs to update the tpr threshold even when no
irq is being injected).

Instead of acking an interrupt when we *think* the guest is ready for it,
and then juggling it around in subarch-specific registers if it isn't (e.g.
page fault while trying to inject the interrupt), separate the injection and
ack.
Subarh specific code now provides two hooks: -queue_interrupt()
The current interrupt controller emulation model supports two functions
for pulling interrupts from the controller into the processor:
kvm_cpu_has_interrupt(vcpu) - is an interrupt pending for the core
kvm_cpu_get_interrupt(vcpu) - get pending interrupt and ack it
This presents a problem

What about merging kvm_cpu_has_interrupt() into _runnable()?
My feeling is that we can keep it separated.
