Right, actually the user needs to call pmc_agent_subscribe()...

Yes, the main phc2sys logic uses that flag here:
while (is_running()) {
...
if (subscriptions) {
run_pmc_events(priv->node);
if (priv->state_changed) {
/* force getting offset, as it may have
* changed after the port state change */
if (pmc_agent_query_utc_offset(priv->node,
1000)) {
pr_err("failed to get UTC offset");
continue;
}
reconfigure(priv);
}
}
...
}
Thanks,
Richard
