Ah ok you are (of course) completely right thx !
What strikes me now .. is that when i used this xhci controller passed through
to a domU i:
a) saw only one IRQ/vector coupled to xhci_hcd in the /proc/interrupts
b) i don't see them being counted now in the dom0 although i use the controller
(i the domU this caused +/- 8000 interrupts a second .. so i should be seeing
something else the 0 i assume.
