I am trying to port a driver that register interrupt handlers for hardware counters in processor.
 
As the IDT is owned by Xen, when I run this in host OS I get errors.
 
I want to know how can I setup virtual IDTs such that I program the counters. On overflow, Xen is notified about the overflow and the interrupt is passed to my driver.
 
what files do I look ? What types of hypercalls I should use ?
 
Thanks for all your help
Shobha
