Re: [Linuxptp-users] Newly Configured Machine Has Very Large Sys Offset
If I don't do one per NIC how do devices connected to each different NIC do the PTP syncing? For instance, I have three LiDARs each with dedicated NIC and needing to receive the PTP time from this system in order to be properly sync'd to each other. Some new information. Of the six NICs, enp0s31f6 that I was working with above is an I219-LM and the other five are I225-IT. The five I225-IT appear to be working as I had expected. I have no idea why the I219-LM is not working properly. I have stumbled upon this post: https://community.intel.com/t5/Ethernet-Products/Onboard-Intel-I219-LM-PTP-synchronization-problem-Driver-e1000e/td-p/1420598 which shows that others are also running into similar issues with the device and I've just posted there too. Please give it a read in case something stands out.

There is a mechanism for receiving notifications from ptp4l, which can be used in shell like this: ( echo 'SET SUBSCRIBE_EVENTS_NP duration 100 NOTIFY_PORT_STATE on NOTIFY_TIME_SYNC on' sleep 50 ) | pmc -u -b 0 It is also supported by the libptpmgmt library, if you don't want to be running this in popen() or similar. There are currently only two notifications implemented, one for changes of the port state and another for clock updates providing the TIME_STATUS_NP message. I think that would work for your 1 and 4. For the others some new notifications would need to be implemented. -- Miroslav Lichvar ___ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
