[lm-sensors] Per motherboard config

The default sensors3.conf does a good job configuring the sensors on a
per-chip basis, but there is a good deal of variation on a
per-motherboard basis as well.  Is it possible to key the config on
the motherboard model, and would there be any interest in gathering
known motherboard configs into the default sensors3.conf to do things
like hide sensors that are known to not be connected and thus have
invalid readings?

No, this isn't possible (at least not currently.) libsensors has now
way to know which chip is on what board on a given system. It could
check the DMI IDs but this could lead to false positives on some
motherboards / graphics cards combinations for example. Plus we have no
syntax to express this in the sensors3.conf format anyway.

We do already gather known motherboard configuration files, see:
http://www.lm-sensors.org/wiki/Configurations
http://khali.linux-fr.org/devel/lm-sensors/
If you have more, feel free to send them to the list and we'll add
them, or we can create a wiki account for you and you add them yourself.

These aren't meant to go to the default sensors3.conf file, we used to
do that years ago and this resulted in a huge default configuration
file which took long to parse and was a pain to maintain.

The missing piece now is a script that would check the DMI data of the
motherboard, look for a suitable configuration file and download it
to /etc/sensors.d semi-automatically. This could be integrated into
sensors-detect or made a separate script. This has been discussed in
the past already, some implementations have even been floating around.
Now it's really a matter of someone taking the time to integrate it all
properly.

Now that sounds like a good idea!
