Yes, exactly the same as what I am thinking.

Anything else would be meaningless. DomU then gets itself a Linux irq by 'irq = evtchn_map_pirq(-1, pirq_from_pciback)'. -- Keir On 23/9/08 09:26, "Shan, Haitao" <haitao.shan@xxxxxxxxx> wrote: > Yes.

Seems some modification is needed, I believe. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
