[Xen-devel] common time reference between domU and dom0

["James Harper" <james.harper@xxxxxxxxxxxxxxxx>]

I would like to be able to measure front/back ring message latency
between a Windows DomU and Dom0. To do this I need a common time
reference between the two, preferably with at least microsecond
precision (latency <1us is irrelevant for my purposes). Does such a
thing exist? A small amount of overhead in measuring this latency is
acceptable.

Thanks

James
