[chrony-users] using chronyd with gpsd, without PPS support

[Michael Ashley <m.ashley@xxxxxxxxxxx>]

Hi folks,

Sorry if I'm missing something obvious, but is it possible for chronyd
to synchronize with gpsd without LinuxPPS support?

My kernel (Debian squeeze 2.6.32-5-686) doesn't appear to have
PPS. I'm using a version of gpsd pulled with git just now, and gpsd
2.95.

I naively tried adding

  refclock SHM 1 poll 3 refid GPS1

to my /etc/chrony.conf file, but it doesn't pick up anything from
the GPS (which is working, confirmed by listening in to the gpsd
socket).

GPS1 appears in "sources" as:

MS Name/IP address           Stratum Poll LastRx Last sample
============================================================================
#+ GPS1                          0    3    10y     +0ns[   +0ns] +/-    0ns

Regards,
Michael
