Might we expect the kernel or drivers to handle retries for us? For example, the kernel uses retry loops with spinlocks to read normal kernel clocks (e.g. ktime_get()).

I agree - also the PTP clocks themselves often glitch or simply reset entirely when ethernet controllers reset. I have enough trouble getting the clock to stay coherent when an ethernet link drops! :) _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
