Temperature/Hardware Monitor for 2.6.* kernels

JetAce44 · Apprentice Joined: 02 Feb 2004 Posts: 152

Hey guys...

Been looking around for a good temperature monitor like MBM5 on windows. Looks like nothing has full support for a 2.6 kernel. I dont absolutely need one, but it would be nice because I know my system runs hot, especially when at a full load doing F@H.

Any suggestions?

Running dev-sources-2.6.1 kernel with KDE 3.2

Thanks guys.

Is your system ACPI compliant? You can get some temperature monitoring via ACPI if it is.

Yessir, it is ACPI compliant. I even compiled my kernel with the CPU temperature support enabled. How can I set this up?

I don't know about ACPI for temperature monitoring, but lm_sensors is the thing for monitoring motherboard sensors, as far as I know. With 2.6, the separate lm_sensors package is no longer needed for the sensor kernel modules: the modules it provided are now included in the 2.6 kernel; the config is under device drivers -> character devices -> i2c). And, here's why some programs that monitor sensor output don't work with 2.6: sensor readings are now in sysfs, not proc.

Recent versions of gkrellm (I'm running 2.1.24) support the sensor readings provided by the sensor modules in 2.6. I've had no problem at all using gkrellm to monitor temperatures and fan speeds running 2.6 on my own machine. If you have the right modules for your system loaded (likely the same as you'd use with lm_sensors, so check its docs if you need help), gkrellm should find the readings, and all you have to do is fiddle with the appropriate settings (factor, offset) in gkrellm's config.

You don't have to do anything; in a console type acpi -t
and you should get back your temps.

If you're looking for a monitoring app, I suggest the acpi
plugin for gkrellm ...

i'm having the same problem. i have acpi_thermal compiled IN the kernel and acpi -t gives me nothing

anyone found a solution for this?

(lm_sensors with I2C report everything but temp's)

if acpi_thermal is compiled in but there is no reading
then I guess your system is not fully acpi compliant

I've heard that acpi can be tweaked by fiddlling with
the dsdt file ... maybe a search on that would help but
I suspect it is far from easy

I've just compiled ACPI into my 2.6.2-kernel, including this:

Ok, did some tweaking and emerging last night after posting, and was able to get some of the thermal/fan/voltage readings with gkrellm. For some reason, I never compiled I2C support into my kernel. After doing that, I was able to get some of the correct readings with gkrellm. My only problem is that it doesnt get the temperature of one of my processors right... not sure how to fix that one. Luckily it's the temperature of my cooler processor.

Onto my next question. Is there any way to install lm_sensors without emerging I2C (because I have a 2.6.1 kernel)? I was thinking about trying out the lm_sensors plugin for gkrellm, but I have no idea how to just install lm_sensors without I2C.

Thanks for all the help guys.

One more question, as I think of it:
Would APM support that I compiled into my kernel be causing me trouble?

Hi... i am running the 2.6 kernels and want to get temperature sensors working. I have an AMD Athlon XP 2600+ on a kx7-333 motherboard (via kt333 chipset).

lspci gives me, among other things, the following information:

0000:00:00.0 Host bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333]
0000:00:01.0 PCI bridge: VIA Technologies, Inc. VT8366/A/7 [Apollo KT266/A/333 AGP]
0000:00:11.0 ISA bridge: VIA Technologies, Inc. VT8233A ISA Bridge
0000:00:11.1 IDE interface: VIA Technologies, Inc. VT82C586/B/686A/B PIPC Bus Master IDE (rev 06)

Now according to what I've read, if I have VT8233A then I need the i2c-viapro module (and the adm1021?), but if I have VT82C586/686A then I need the i2c-via and i2c-isa modules. So which is it?

I have tried many combinations of the above modules, but acpi -t always tells me "No support for device type: thermal" and gkrellm can't find any sensors.

Any help is much appreciated, thanks!

Hi apberzerk,

Did you get your sensors up. I did have them working with ACPI build into 2.4.2 kernel (or at least I got a temp from acpi -t) .In this state gkrellm did not diplay anything with the plugin.

I have rebuilt with ACPI as modules 'cos this seems to be needed for anticiapated 2.6 I want.

BTW , have you played with your KX7-333.

I have the same board with an athlonXP th'bred and it overclocks like hell.

I am currently showing a clickspeed of 2.33 GHz !! and it is stable at 52 C even during a big emerge. (Good solid copper heatsink Cooler Master)

FYI I have managed to get the FSB to run at 188 but rolled back to 186 for gen use.

This chip is supposed to clock at 1.67Ghz. Incredible what you can do with a good AMD!!

Did all my testing under win98 with MBM5 , I am hoping to get the sensors sorted out so I can keep an eye on Linux temps.

How do I know if my system is ACPI compliant.
I have APCI compiled in the kernel, because I thought that I need it to shut down the system. I am not using for any other reason. But, I am getting some hard disk related errors, and I read in a topic, that I should check whether I am getting those errors without ACPI support.
So, back to my question:
What do I need to do to find if my system is ACPI compliant?

Thank you

I run 2.4.2-r7 on my KX7-333

I find the i2c stuff in make menuconfig as follows:

Character device
I2C support

here I select

<M> I2C support
<*> I2C mainboard interfaces

<M> VIA technologies ................
<M> proc interface
<M> dev interface

All this compiled in , rebooted.

I set the MODULE lines you suggested in /etc/conf.d/lm_sensors

Try /etc/init.d/lm_sensors start
Loading i2c-proc....
Loading i2c-viapro
Loading i2c-w83781d

Fine so far.

acpi -t

No support for device type battery
No support for device type temperatue

(Note I was getting temp info earlier when not compiles as modules to the hardware is there)

sensors-detect
No i2c devices files found. Use prog/mkdev/mkdev.sh to create them.

I dont have a mkdev and I think I am missing a step ,

You say you used sensor-detect un 2.4 , can you see what I am missing.

I think I need to load a module , but what and how?

Thx

PS

I have i2c_core but not i2c sensor , does that help?

Thx

I added i2c-dev to /etc/conf.d/lm_sensors

This enabled sensor-detect to do its job.

It set me up w83781d as you indicated for your board , added i2c-isa and took out i2c-dev

These all load at boot time.

I build acpi support back into kernel as a second check and acpi -t now returns the temp again.

Hwvr, sensors still says "No sensors found!" an gkrellm shows nothing.

Well that's cost me a day's work , and still nothing concrete. I give up!

Thanks a lot for your input.

Gentree · Posted: Sun Mar 07, 2004 11:21 pm Post subject:

It seems it should be sufficient to modularise i2c in kernel config to negate re-emergeing every time.

Hwvr, emerge lm-sensors is failing with 2.4.22-r7 so it looks like I shall have to make do with acpi until I move to 2.6 .

Thx again. Gentree
