AMD K10 cpu thermal sensor

vit · 2009-07-21 20:03:12

Does anybody know about K10 thermal sensor support in lm_sensors? In theis svn changes it's listed in 3.0.0-rc2 (http://lm-sensors.org/svn/lm-sensors/trunk/CHANGES), but I have no modules in my Arch x86_64.
Where could be the problem?

So after the booting method can't it work ? What's the error message when you try, or what's in the syslog? Why do you think the only reason just the missing module can be?

There is no K10 driver yet for lm_sensors. That is why it doesn't work. Detection of a K10 CPU works fine as per the page you linked to-but without a driver to talk to the thermostats, you won't get any data.

Look at the AMD listing on this page: http://lm-sensors.org/wiki/Devices for more details.

I installed the package, and sensors-detect says:

Some south bridges, CPUs or memory controllers contain embedded sensors.

Note: there is no driver for AMD K10 thermal sensors yet.
Check http://www.lm-sensors.org/wiki/Devices for updates.

And lm_sensors still gives no thermal readings.

Maybe it's in the early phase. hm... interesting, can you ask from the author/vendor too ?

That driver has been in testing for over a year, and the patch was provided in an email attachment from the author...which the AUR package should have added to lm_sensors.

From this email string:

To make this work:
1. Install package
2. Load module k10temp (modprobe k10temp) and if you want it permanently add to rc.conf.
3. Rus "sensors" and check if it's working.

Actually I don't know how to modify sensors-detect to say it knows the sensor. But if you insert the module and run "sensors" it reads info from it and display that (I checked if it's working - it increases the temperature with CPU load and then decreases it. But absolute temperature value haven't been tested). I think it's a bit easier to make this module then creating a separate lm_sensors package with this patch.

Bingo-you need to load the module manually/add to rc.conf to get it working.

It only outputs CPU temp, and no fan speeds...but it is better than nada.

Fan speed are controled by other chip. On my it's shown after "sensors-detect".
