The impression I get is that ntpd should be treated as infrastructure, and have power management states, but Red Hat are treating it as an errant application that needs to be modified to avoid upsetting the power management apple cart. E.g. after resume from RAM, it needs to progress the clock discipline algorithm forwards (including extra corrections for temperature excursions) before anything is allowed to read the value of the clock, and after resume from disk, it should probably do a restart. The latter greatly increases the importance of fast convergence, and without specific compensation for temperature variation, even resume from RAM needs the ability to respond fast to frequency hits, possibly conditioned on just having done a resume. > > The basic assumptions about the host systems ntp runs on are > changing fast! _______________________________________________ questions mailing list [email protected] https://lists.ntp.org/mailman/listinfo/questions
