Unfortunately i don't know how it works.

I will recheck later when i get back to qemu. I will pull the latest HEAD and
fix IRQ
affinity specification. But, i think that most likely you'll have to debug this
yourself.
Because i suggest it will work. :)

I guess that the correct class will be returned. Otherwise it would not work
at all. You
can check this if you want to.

Ok. Then it looks like i'm going to be the first to do this. I hope you'll
complete the
integration soon because vGICv3 has to be based upon your work.
