Doesn't sound aweful, but not great either. > 2. Use libgpsd to get the time, but that adds a dependency to gpsd No, I won't use that library in linuxptp. Before implementing the current solution in nmea.c, I tried really hard to use gpsd, hoping that it would "just work" because of the multiple different nmea and binary protocols that it has. That seemed like a compelling feature. However, I couldn't get it to work with either a commodity gps or a high end, survey quality gps. > I might also be able to use gpspipe and socat to get the NMEA sentences > from gpsd to ts2phc, but that is not very elegant. This is best approach IMO. You can wrap gpspipe|socat in a systemd job to get automatic restarting and logging and so on. If the gpspipe|socat combination is too flaky to keep running, then writing a little C or python program to read the UART and publish two sockets is pretty easy.
