[Xen-devel] Newbie Q -- how to setup virtual IDTs ?

[shobha ranganathan <shobha_ranganathan@xxxxxxxxx>]

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
