I used the ppskit-light 2.6.15-1 patch on my 2.6.16 kernel, I had to
manually edit in a couple of rejects but it's then compiled and working
You may also need to build NTP from source, if so there are a couple of
header files that need copying in or PPS does not actually work..
I can't remember what they are but I mentioned them in an older post after
getting my setup working.
I'm using a GPS25 module, my setup for it in ntp.conf is:
# NMEA Clock using Garmin GPS
server 127.127.20.0 mode 1 version 4 prefer
fudge 127.127.20.0 refid PPS flag2 1 flag3 1 time1 0.000 stratum 1
I also have a couple of local servers and pool servers configured to give
NTP it's majority decision capability.
You don't need a separate PPS device, it's built in to the NMEA refclock.
You may need a symlink from the appropriate tty to pps0 and gps0
I'm using Centos 4.3 which uses udev, I added these lines at the end of
# Add symlinks for NTP service
