I'm searching for some documentation on the merits (or otherwise) of using the kernel pps code (fudge flag 3) in the nmea and pps drivers. I have a box running FreeBSD 5.4 that has a GPS18lvc attached to a serial port with PPS hooked to DCD and a TrueTime GPS clock PPS output hooked to it's parallel port.
I was having clock hop issues and in order to get the tos mindist feature I upgraded to rc1 however "enable pps" is no longer part of rc1 (where did it go?) so I'm not entirely clear on what settings I should be using and what the merits of the various options are. Can somebody point me at come discussion of: "enable/disable kernel" why would I want to disable the kernel code? What practical effect do this have? "enable/disable pps" - where did it go and why is it not longer needed? What did it actually do? "fudge flag3 1" what are the merits of using / not using this flag?
