The current SHM driver looks for a sample each polling interval. The documentation for gpsd suggests using minpoll and maxpoll of 4.
I've fixed the SHM driver to look every second. The refclock infrastructure already had a FIFO and code to process things like this. This reduces the jitter significantly. (At least in my test setup.) I also added some clockstats printout if flag4 is set. I'm testing with gpsd. Does anybody have a list of other packages that feed the SHM driver? I'm looking for people to help test this, just in case there is something strange that I broke. If you are interested, please contact me by email. -- These are my opinions, not necessarily my employer's.
