Hello List,
I understand that linuxptp code base as is requires Linux kernel version 3.0 or
newer. For platforms where kernel 3.x is not yet available, is it possible to
backport linuxptp into a kernel 2.6.30+? If so, what would need to be done?
Does it make sense to modify the hardware abstraction layer to use some
specific NIC FPGA TX/RX timestamping and driver (instead of PHC API), and keep
the linuxptp PTP protocol stack part intact?
I came across a discussion panel where it indicated Red Hat backported the
linuxptp PHC API and drivers into RHEL6.5 / CentOS 6.5 (kernel 2.6.32).
The Linux kernel PHC API and MAC/PHY drivers to control hardware clock are in
kernel 3.x, however SO_TIMESTAMPING support for ethtool, sockets and
timestamping has been added since kernel 2.6.30+.
Thanks.
Daniel
