I'm afraid that's a rather open ended question.
http://wiki.xen.org/wiki/Asking_Xen_Devel_Questions might help you to
formulate something we can answer.

To help you get started the event channel hypercall interface is
http://xenbits.xen.org/docs/unstable/hypercall/include,public,event_channel.h.html
there is also some documentation in
http://xenbits.xen.org/docs/unstable/hypercall/include,public,xen.h.html#Struct_shared_info

You can find the kernel side in drivers/xen/events.c (mostly).
