Subject: LinuxPPS core (Version 2): the PPS Linux implementation.
Date: Tue, 10 Feb 2009 15:05:51 +0100	[thread overview]
Message-ID: <1234274752-29847-1-git-send-email-giometti@linux.it> (raw)

This patch adds the PPS core support into Linux.

Currently I just propose the "core" so after inclusion we can add all
other related stuff as suggested by several people in this list. :)

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
=========

Version 1 -> 2
--------------

* fix race during PPS source registration.

* PPS_CHECK removed.

* not needed check in pps_exit() removed.

* Printing stuff on exit removed.

Version [full patchset] -> 1
----------------------------

* stupid filenames removed.

* kernel-doc documentation of exported symbols.

* old BKL-locked ioctl removed.

* !uarg checks in the ioctls removed.

* pps.h revisited but not splitted, since several stuff are shared between
  kernel and user land (I hope this will not stop inclusion...)
