At that point, it becomes a discussion of two concrete pieces of code
verses hand waving.
Out of curiosity now, what _are_ the behavioural differences between
the in-kernel irqchip and the qemu one?
Are the differences significant to guests, such that it might be
necessary to disable the in-kernel irqchip for some guests, or
conversely, necessary to use KVM for some guests?
No, the behavior differences are not terribly significant for the apic.
Disabling it is really most useful for debugging purposes.
