Re: [Linuxptp-users] Compile issue in RHEL v6.3

[Keller, J. E <jac...@in...>]

Hi,

So the problem is that the kernel clock support for ptp hardware clocks
was not backported until 6.4, and I wouldn't even trust its backport
until at least 6.5

I've done some decent validation of Intel stuff on 6.5 and it works well
enough, but you have to trust that Redhat backported the complex feature
correctly.

6.3 could do software timestamping, that really is about all.

Regards,
Jake
