In allocating event channels, I'm doing EVTCHNOP_alloc_unbound and then passing the returned event channel number to Dom0 via xenbus. Is there anything else I need to do? Do I need a specific hypercall to bind the event channel to cpu 0 only? I'll check the 'unmodified drivers' source... The thing is, my performance testing has shown good results for SMP (vcpus=4) and UP, but Bart has reported that he only gets good performance when he checks the vcpu_info for the cpu that the interrupt has been triggered on.
