Can it be documented in api.txt as well?

All LVTs are masked on reset, so the timer becomes ineffective. Letting
it tick nevertheless is harmless, but will at least create a spurious
trace event.

Introduce a memory region type that can reserve I/O space. Such regions
are useful for modeling I/O that is only handled outside of QEMU, i.e.
in the context of an accelerator like KVM. Any access to such a region
from QEMU is a bug and will be reported as such.

To enable migration between accelerated and non-accelerated APIC models,
we will need to handle the timer saving and restoring specially and can
no longer rely on the automatics of VMSTATE_TIMER. Specifically,
accelerated model will not start any QEMUTimer.

Some weeks back I posted my MSI rework for qemu-kvm that shall once help
integrating those bits into upstream. After that I wondered how a
rewritten in-kernel irqchip model could look like and make use of this.
But then I realized that there is actually no technical need to role out

Analogously to the APIC, we will reuse some parts of the user space

The KVM in-kernel APIC model will reuse parts of the user space model,
namely the vmstate, reset handling, IRQ coalescing tracker, some init
steps and the base and tpr set/get routines. For the latter, we also
prepare set callbacks as KVM will override those.

This introduces the alternative APIC model 'kvm-apic' which makes use of
