To be honest with you, I'm a bit concerned that it still won't work as
intended even if I remove the error from posix_clock_add(). This is
because find_dst_clock() from phc2sys finds clocks by phc_index. When
you run phc2sys between this /dev/ptp_kvm and

canonical way of finding the PTP char device corresponding to an

There is no network interface associated with this cloc

Thanks for the quick reply. Understood, digging this out properly (ie.
finding the /sys/class/ptp/ptp*/dev file with a matching minor to that
of the device node) would add a lot of complexity. However, looking at
the alloc_chardev_region() call in the ptp d

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

the PHC number using ioctls on the char dev

As of commit 380d023abb1fdce0dba9d58ca1abaf2e2de5488f PHC device nodes
or symlinks named as "/dev/ptp*" where "*" is not a number cause phc2sys
to fail with "failed to parse PHC index". Note however, if the filename
does not match this pattern, it happily continues with no PHC index set.
