kernel, lm-sensors and Phenom/Phenom-II temperature data

I had read a few monts ago that a patch had been made to enable lm-sensors to read temperature data from Phenom - and Phenom-II - CPU cores.

I do not know if that patch has to do with the kernel (k8temp), with lm-sensors, or both.

But anyway, do we have any news on the subject?

Has any progress been made on the subject?

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

I'm kinda curious about this too, since I just upgraded to an AMD Phenom II X4 955.

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

What I can find in the mailing list is info from mid-2008: they are working on it, there is already a patch that seems to work OK - read the thread there for further info, there is more on the topic scattered throughout the list. I think they decided to merge that stuff with the k8temp-driver, but I can't find the relevant info right now.

The k8temp-module in the current package does read a/the temperature, but at first glance it seemed pretty low, but maybe the cooler that comes boxed with the CPU is pretty badass (it certainly sounds badass :-( ). However I haven't tested this in any meaningful way.

Yes I had read these messages but they were over a year old, and that's why I asked here if somebody had any newer information.

By the way, a maybe silly question.

I know how to use a text (diff) patch, and how to incorporate it in a PKGBUILD.

But how do I use a binary patch, like the one offered in the attachment mentioned above?

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

You could always try the k8temp module and compare the values reported by it with those from the BIOS. If they match you should be fine with k8temp. I can't check right now, because I'm not a tmy Phenom II box.

Yes, but that's exactly what I am asking right above.

How do I get the modified k8temp module?

So that I can build a package for it, install it and see how it behaves.

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

OK, maybe I misunderstood.
I wasn't referring to any modified version, just the k8temp from the current package (Because I couldn't find anything more recent than the above linked patches either).
So you're saying that you've already tested that one and it doesn't work correctly?

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

I did a quick check with the current lm_sensors package and k8temp on a Phenom II X3 720.

Bios reports 34°C CPU @ 3144RMP fanspeed and 18°C Sys. Sensors immediately after boot says 31°C (temp1, I assume CPU), 20°C (temp3, I assume sys) and fanspeed of 3171 RPM. Something seems to be working.


[edit: I found what I was lookoing for:
http://lists.lm-sensors.org/pipermail/l … 25495.html
http://lists.lm-sensors.org/pipermail/l … 25680.html ]

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

This is page I found on how to install a k10temp kernel module. Once installed lm_sensors can find it:

http://blog.morrigan.ch/?p=9

On the Phenom II 955 I get one temperature read out, temp1, which should be the processor. I'm not sure if I trust what I see. With all four cores running extremely high the temperature only read 46C. The same operation with a 6400+ with the exact same fan would have approached 60C. It could be correct, but I'm not real confident.

Re: kernel, lm-sensors and Phenom/Phenom-II temperature data

skottish, I have done some testing with my Phenom II x4 955 and at load 46C is about right, I've tested this with both the k10 module and under windows, it heats up FAST but doesn't seem to peak much above 45C. Used several temp monitor apps, including AMD Fusion, all report the same temps on mine.

Even under full load? If so, that's the best news that you could have given me. Wow.

I had a few reasons not to trust it. The on-board CPU monitor shows the chip idling at 40C. k10temp shows around 30-32C. With that being said, if you're seeing the same numbers under Windows, that goes a long way in inspiring trust with me. It also explains the lower peak temperature that AMD has for this chip (62C).

Thanks for the happy information!
