Thanks for the information. That helps.
What I do not see fully clear is the role of phc2sys. It is used to synchronize the PTP clock from my Ethernet device to the Linux system clock. There is likely a drift/offset between this PTP clock and the Linux system clock. This drift/offset has to be corrected by the phc2sys tool. What kind of information do I get when I call the 'pmc" management client? Is it the drift/offset of the PTP clock (Ethernet) or is it the drift/offset of my Linux system clock? One more question related to phc2sys. When I use a PC as PTP master, I have to call phc2sys like # phc2sys -c /dev/ptp -s CLOCK_REALTIME -w When I use a PC as PTP slave, I have to call it like # phc2sys -s /dev/ptp -w If I do not explicitly specify which of the PCs should run as master or slave, there is a negotiation between the available PCs. One of the PCs will be made the master. Is there a way to call phc2sys to distinguish automatically between master and slave operation mode? Or how do I have to call "phc2sys" in the situation when I do not know if the PC will be master or not? Thanks for any help on this!
