[Xen-devel] Event channel questions

["Carl Holtje ;021;vcsg6;" <cwh0803@xxxxxxxxxx>]

All-

The interface docs discuss event channels, and state "they provide little
bandwidth for communication per se, and hence are typically married with a
piece of shared memory to produce effective and high-performance
inter-domain communication".

Can someone help define 'little bandwidth' and 'high-performance' in less
than relataive terms? What is an appropriate application of the event
channel if it is low bandwidth?

Also, are there examples around of using event channels, both with and
without grant tables?

Thanks!

Carl
