[Xen-devel] Re: Setting callbacks for events

["Srujan D. Kotikela" <ksrujandas@xxxxxxxxx>]

Hi,

I found do_set_callbacks function in x86_64/traps.c . This 
function is taking 3 parameters. event_address, failsafe_address, 
syscall_address. 

If I have to setup the event notification 
handler (similar to hypervisor_callback in mini-os) is do_set_callback 
function the way to go? 

If so, should I edit entry.S and include hypervisor_callback code there? 

Is this function called by hypervisor/kernel? I mean which of the hypervisor/kernel supposed to set these things? 

Is there no function where I can set up handler for event_port individually.

How do I set/register call backs for events? I saw the hypercall HYPERVISOR_set_callback() which takes event selector, event address, failsafe selector and failsafe address as parameters. I was expecting a function pointer to be passed. Can anyone explain me how work this out?
