That I have already done, but I want the ntpd to discipline not the kernel clock but an external one in order to implement hardware timestamping in a next step. > If you are bound and determined to make your own code, the > place to start is in configure to specify your clock model and then > systime.c in libntp. I found that, but I'm not sure, that this is all I have to do, since there are calls from ntp_loopfilter.c directly to adjtime(), which is not covered by the functions in systime.c ... > Be advised that you are not likely to get much > support for modifications to that file as a great deal of knowledge is > required to understand the control loop and which variables you can or > should tinker to match your hardware. > Thanks for the warning, I won't bug anyone with problems in the control loop. :-) Regards, Patrick _______________________________________________ questions mailing list questions@lists.ntp.org https://lists.ntp.org/mailman/listinfo/questions
