Ok. I'm going to add them under "testing".

provides a set of chars devices, one per PPS source, which can be used
to get the time signal. The RFC's functions can be implemented by
accessing to these char devices.

This patch adds into the PPS's documentation directory a possible
implementation of the PPS API (RFC 2783) by using the LinuxPPS's char
devices.
This file is not just an example but it can be used into real
systems. :)

Here some utilities and examples about the PPS API and the LinuxPPS
support.
* ppsctl.c implements an useful testing program, while
* ppsfind tries to help the user into finding a specific PPS source by
using its name or path.

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

Hello,
here my patch for PPS support against kernel 2.6.24:
http://ftp.enneenne.com/pub/misc/linuxpps/patches/ntp-pps-2.6.24.diff
The code has been tested by some guys intered in PPS stuff and it
seems ok. :)
Please report your suggestions in order to get kernel inclusion.
Thanks in advance
Hello,
on my custom board I have some leds mapped on a dedicated chip
connected via i2c bus.
If I try to use the heartbeat trigger I hang the system... I suppose
it is due the fact the led_set_brightness() function is called inside
a kernel timer.
How I can solve this problem? I thought to modif
