jhenning Posted August 7, 2015 Share Posted August 7, 2015 Hi, About the problem of absolute timekeeping on Power PMAC, I wonder if anyone has experience with PTPv2 (IEEE1588-2008). SourceForge among others has a daemon available for Linux. If this locks in Linux time, then Sys.TimeOfDay should keep time with the PTP grandmaster clock, right? Thanks!

KEJR Posted August 10, 2015 Share Posted August 10, 2015 I have not tried PTPd but I know that just installing the following package works for initializing the basic Linux time/date. Its not going to be nanosecond accurate but for basic tasks like file timestamping it should be perfect. ntpdate I believe you just need to do apt-get install ntpdate For details regarding installing software and the readonly filesystem stuff please see some other posts if you aren't already familiar with this.

Hi jhenning and all, did you manage to make the PTPd work on the PPMAC? I understand that the HW PHP works with kernel version >= 3.19.3; does the newest PPMAC runs this linux kernel? thanks Link to comment Share on other sites More sharing options...

Let me know if you find out anything. Link to comment Share on other sites More sharing options...
