FYI, you should be aware that this method reads time stamps over the PCIe interface. Because of the delay and uncertainty in reading single values over PCIe, this introduces a time error on the order of microseconds. You can avoid this error by directly feeding the 1-PPS into PTP card that supports external time stamps (like the Intel i210). Then you can write a little servo to discipline the PTP card to the GPS clock. > I mean to say that I am observing offset at slave side and noticed that the > offset from master is large for large distance between master and slave. Not sure what you mean. Can you post the client side ptp4l logs for both cases?
