Normally if the event channel is for communication between domain 
and Xen, it's categorized into VIRQ group. All supported VIRQs are 
listed in xen/include/public/xen.h. Then you need to explicitly register
new added VIRQ to dom0 interrupt sub-system by 
bind_virq_to_irqhandler. Example like drivers/xen/console/console.c. 
If the new VIRQ is meaningful and you'd like to propose it for widely
used, then please send out patch plus description to this mailing
list for discussion.

Thanks,
Kevin
