Subject: high res timestamps and SMP
Date: Wed, 19 Nov 2003 17:40:08 -0500	[thread overview]
Message-ID: <3FBBF148.20203@nortelnetworks.com> (raw)


We have a requirement to have high-res timestamps available on SMP systems.

Assuming that we are running identical cpus, is a sync-up at boot time 
enough to give usable time values, or do I need to do force periodic 
re-syncs?

We're currently looking at MIPS, x86 (Xeons), and PPC.

Thanks,

Chris
