[Xen-devel] XEN event channel (interdomain communication)

[Sankaran Sivathanu <ssankaran@xxxxxxxxx>]

Hi, 

Could someone please briefly explain the differences between these calls in the XEN event channel framework ?  I couldn't find resources that talk about these calls.. 

My goal is simple: send an event from Dom0 to DomU and invoke a handler in DomU when an event is received.   I wish to do this in kernel level.. I am a bit confused on what calls to use and also about how to allocate port numbers.  So it would be really helpful if someone could tell the purpose of these calls.. 

bind_caller_port_to_irq

bind_listening_port_to_irq

bind_listening_port_to_irq
bind_interdomain_evtchn_to_irq

bind_caller_port_to_irqhandler

bind_listening_port_to_irqhandler

bind_listening_port_to_irqhandler
bind_interdomain_evtchn_to_irqhandler

Thanks!

Sankaran.
