| Thread-topic: | common time reference between domU and dom0 |
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.
