Subject: LinuxPPS (RESUBMIT 7): the PPS Linux implementation.
Date: Wed, 10 Sep 2008 09:52:19 +0200 [thread overview]
Message-ID: <1221033149-15405-1-git-send-email-giometti@linux.it> (raw)
In-Reply-To: <>
This patch set adds the PPS support into Linux.
PPS means "pulse per second" and its API is specified by RFC 2783
(Pulse-Per-Second API for UNIX-like Operating Systems, Version 1.0).
The code has been tested with the NTPD program
(http://www.eecis.udel.edu/~mills/ntp/html/index.html) and several GPS
antennae.
Changelog
RESUBMIT 6 -> 7:
* A new line discipline has been added in order to leave untouched
the serial ports code (as suggested by Alan).
* n_tty.c exports only GPL symbols.
* ioctl numbers fixed in order to avoid any conflicts.
* Last patch (0010-PPS-low-level-IRQ-timestamps-recording.patch) implements
low level IRQs timestamps recording which mproves PPS precision but can
be dropped for kernel inclusion! As suggested by Alan: "After that is
sorted/merged we can come back to working out the best way to improve
the IRQ and HARDPPS hacks."
