These are two different ways of getting the PPS timestamp into NTP. As
I understand it:
(A) requires that gpsd has some way of getting the PPS timestamps into
one of its shared memory segments. The only time I've used this is with
It is different. You need some code which reads and timestamps the
interrupt. I believe tht gpsd can do that. Then you need some way of
getting that timestamp to ntpd. that is what the shared memory does (it
is common piece of memory shared between two programs.)
Now, you can use the kernel pps code, you can use shmpps ( which reads
the serial or parallel port interrupts and puts the timestamp into the
shared memory segment etc)
a program of Folkert's which worked on the Raspberry Pi to read the
timestamp when a GPIO pin changed in user-mode, and insert that
timestamp into gpsd's second segment (numbered 1).
Aside: I couldn't find a description of using units 0 and 1 with the
type 28 shared memory driver. It seems that the timestamps in unit 0
may be from the serial NMEA data, and those in unit 1 from the PPS data,
and hence the prefer on unit 1. Perhaps someone could confirm this.
I looked at:
http://www.eecis.udel.edu/~mills/ntp/html/drivers/driver28.html
(B) requires that the OS support PPS transitions, and could be tested
with a command such as Folkert gave:
This is another, kernel type code to timestamp the interrupt. As you say
it puts out the info into /dev/pps*
# cat /sys/devices/virtual/pps/pps0/{assert,clear}
1372528130.997131540#54
1372528131.097120120#54
That is just a monitoring peek into the kernel module.
I think most people try to use this with the OS kernel supporting PPS,
to give better results than with user-mode support.
To timestamp the pps, you have to have some module (ie kernel level)
timestamp process. shmpps, gpsd, the kernel pps, write your own,
That's about the limit of my knowledge and could easily be wrong!

Either a file on your PC, or updtream ntp servers you use?
Probably some Linux machine running a ancient version of NTP
for no _good_ reason, as they so often do.
I love policies that won't let you run the current version,
that has hundreds (thousands ?) more bugs fixed over the last decade,
than the version that is in a distro,
and policy won't let it be replaced, removed, or fixed.
