That would be me and my ts2phc patches. Sorry for that. Prior to that change, posix_clock_open() used to simply not populate *phc_index when passed a path to a PHC. I don't think there's any kernel API to deduce the PHC number using ioctls on the char device itself, so for my use case it would be pretty odd to have a PTP device named differently than /dev/ptpN. Nonetheless, phc2sys does not need to know the exact number of the PTP clock, and therefore, what I can do is move the error one level upper, at the caller. I'll try to come up with a patch tomorrow. _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
