Bug Description

there is no support for k10-thermal-sensors in kernel 2.6.32. kernel 2.6.33 seems to have this support and sometimes it might be very useful one see temperature and/or fan rotation of the computer.
so please include the support for k10 thermal sensors if possible.

Sounds good, thanks.

Hi paulle, I'm not clear as to what you are asking for in this report. Are you asking for this support to be patched in to 2.6.32 from 2.6.33 for Lucid?

I'm not paulle, but yes, he is. 2.6.33 contains k10temp, 2.6.32 does not, so no thermal control for popular CPUs. The driver is pretty small, adding it will not affect anything else.

summary: - there is no support for k10-thermal-sensors in kernel 2.6.32
+ k10temp: there is no support for k10-thermal-sensors in kernel 2.6.32

I have been using the k10temp (built manually) since kernel 2.6.31 within several different Ubuntu installations with success.

As Ubuntu Lucid is going to be an LTS release there is no reason not supporting this sensor. As it is included in the final 2.6.33 kernel it can be seen as being stable enough.

Ubuntu Lucid will be installed on a lot of servers and most of the installations on AMD systems will be using a K10 processor, namely Opteron. Lm-sensors is used often as a base for collecting sensor data for monitoring and thermal data is one of the very vital things in server environments.

I followed all those discussions and the progress of KMS/DRM/GPU stuff going backported into 2.6.32. So this little tool would be the least of all the problems that may be introduced by backporting.

I for myself am not asking for a 2.6.32 patch. I would rather see it in the backports-modules section. As most vital hardware does provide other sensors via SMBus or the like I don't think that it is vital to exist in the basic kernel image.

This is not criticism, I just want to push it to exist somewhere in the official repositories.

The K10temp module is also required for newer Athlon chips (like the 235e that I use), so not having it in 10.04 Lucid will be a major issue for people who expect that hardware that has been available for almost a year is supported by a new release.

I would appreciate k10temp support because I have Phenom IV CPU and Turion X2 Dual Core Mobile both need the k10temp module. Do you accept dkms or m-a patches for this?

k10temp-dkms added to my ppa: https://launchpad.net/~lorem-ipsum/

I would appreciate test and feedback.

Nearly perfect!

+ The multiple kernel feature, very nice and convenient. But I have some upstream kernels installed that already have the module compiled and enabled, so you should check for that and disable integration for those kernels. In addition I noticed that it only integrates the module into kernels that are at the version I currently run and above, but e.g. I have the stock Lucid kernel "2.6.32-21-generic" but I currently run "" (like stock kernel plus a patch, same config). And here it doesn't update the stock kernel. Is it because "-" is lower than "."?

Anyway it just loads fine after installation:

tried k10temp and worked like a charm.
$ sudo sensors-detect
and added k10temp to /etc/modules

$ sensors

Use the k10temp (lmsensors/k10temp/temp1) in plasma-widget temperature.

I've been using k10temp since 2.6.28 (jaunty) by applying the kernel patch. I am surprised support still hasn't been added for such common CPU's....

I've also put up a k10temp ppa some time ago:

Upgraded to Lucid/10.04 yesterday. Now sensors work as expected.

Please help? Thanks

I get the same error. I guess the PPA has disappeared.
