A new version of the patch: http://people.freebsd.org/~avg/periodic_resettodr.diff Some notes: - this patch doesn't implement any resettodr enhancements proposed earlier: making it non-blocking/asynchronous and saving time closer to seconds boundary; - the patch adds code for saving time on shutdown, adds logic for checking ntp synchronization status and for dynamically stoping/(re-)starting the callout via period sysctl; - the patch consists of two pieces: the first is abstracting ntp status check into a separate function and the other is all the time saving code; - I don't feel that kern_ntptime.c is best place for this code, I only chose it because of ntp status checking; perhaps ntp_is_time_error needs to be made public and the code moved to a better file; suggestion are welcome! I also welcome any comments and suggestions on code style, identifier naming, logic, strategy, etc. Thank you! P.S. it seems that machdep is not the best place for "RTC" sysctls, but I am deferring this issue at the moment. -- Andriy Gapon _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
