[maemo-developers] [maemo-developers] Maemo Alarm/Notifier Interface

[From: Jason Mills]

A few items:

0) The RTC subsystem is served off a chip known as "Retu". Most of the ASICs
on the Nokia 770 board seem to have nice nordic names to them. :-)


1) The RTC subsystem only supports one future alarm event, and that event may
not be more than 24h59m from "now". Maximum alarm granularity is +/-1 minute
or so.


2) The actual definition of "now" is a bit arbitrary, because of how the RTC
synchronization works.


3) There is a functional, albeit spartan CLI utility already available to
talk to the RTC subsystem, -and- to set/check the alarm.

4) The osso_alarm and osso_notifier daemons are missing at least from the
2005.51 Nokia build. No bug is currently filed against this, and I haven't
had a chance to file one yet. I think, though am not 100% sure, that these
two daemons are required in order to fetch the actual alarm signal from the
RTC subsystem.
