Subject: LinuxPPS core (Version 3): the PPS Linux implementation.
Date: Fri, 22 May 2009 08:12:32 +0200 [thread overview]
Message-ID: <1242972753-22992-1-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 2 -> 3
--------------
* include file splitted up.
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...)
