CPU Temperature?

CPU Temperature?

[Harald Dunkel]

Hi folks,

Is there a standard interface to watch the temperature of the CPU (e.g.
Athlon Thunderbird)? Or is this a feature of my main board?

How can I access the CPU temperature, fan speed etc. from Linux?
Or is this too hardware dependent to implement a common interface?


Regards

Harri

hi, you want to look at the lm_sensors project...

the temperature voltage and fan sensors on your mainboard should be
accessible without to much trouble...

Exactly what I was looking for.


Many thanx

Generally it comes from the mainboard

lm-sensors - it works well. Its shipped in some vendor trees

Whats the schedule to merge with mainline kernel? Right now we have two
i2c trees -- the one in the kernel and the one in lm-sensors...

2.4.10-ac4 contains the latest i2c code.

Of course it doesn't work. We've performed a software upgrade.

On my Abit VP6, hardware monitoring is on IO address 0x294h to 0x297h.
Why do we have to patch kernel and load module?  Isn't there something
simpler which we can compile and run as root?

The -ac tree is in sync. Hch did the leg work for that

Of course I would be interested to get the lm_sensors included in the
kernel, too. Is this still an option for 2.4.x?

It doesnt break the machine, replace key parts of the core of the system or 
change critical interfaces. By conventional standards its ok, by 2.4.10 
standards its not a candidate 8)

I'm certainly prepared to go through the files trying to poke holes in them
and its stuff I think just about every vendor already ships anyway

Latest CVS release has even changed all the malloc includes to slabs, so 
is there any non-cosmetic problem ?
