It would be interesting to poke around in pps-client to see what it actually does. There are two ways to use PPS. One is to to capture the data and then feed the offset into a normal algorithm like ntpd uses. The other is to set a mode bit so the kernel does all the work. The latter doesn't work with the NO_HZ scheduling option in the kernel. Most distros ship a kernel with that option enabled to save power. Rebuilding the kernel is a strong hint that they want to use the kernel mode. If that's the case, you can use ntpd to do the same thing. It's a flag bit to the PPS driver. It would be interesting to compare whatever pps-client does with what ntpd does (same kernel) with and without that flag. -- These are my opinions. I hate spam. _______________________________________________ devel mailing list devel@ntpsec.org http://lists.ntpsec.org/mailman/listinfo/devel
