Re: [Xen-devel] driver domains

Hi Mike,

Interrupts are passed on to the domain that registers the irq handler (and
only priviledged domains are allowed to do so). Hence the interrupt would be
sent directly to driver domain (unless it is being shared by multiple domains,
in which case it would go to all the domains).

A good start would be to look at xen/arch/x86/irq.c, specifically at 
pirq_guest_unbind and __do_IRQ_guest.

Himanshu thanks to you and Ian for responding!
