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...)
