Re: [gentoo-user] Pentium D Temperature and Frequency Scaling

[Richard McCombie]

Thank you for the suggestions, Dale and Stroller.

I have an Athlon64 machine, and in order to access the CPU temperature
on that, I simply built the 'k8temp' module. The option to build the
'coretemp' module is on the same page of menuconfig. However, coretemp
isn't applicable to my Pentium D 3GHz.

I would like to know if there is any way - other than by using
lm_sensors - that I can get at the temperature of my CPU. k8temp works
for AMD Athlon64 CPUs, coretemp is for Intel Core CPUs, is there a
similar solution for Intel Pentium D CPUs?


Also, can anyone enlighten me as to whether it is correct that my
Pentium D 3GHz can only drop to 2.4GHz at the lowest, rather than
anything lower, while doing frequency scaling?


Thanks again,
Richard

 sys-apps/lm_sensors  ??

 Or is this only for measureing tempertaures on the motherboard?

 Stroller.




 It may be that the drivers are in the kernel options but he just needs
 to know which one out of the dozens that are available is the correct
 one.  I monitor my CPU and mobo and I don't have lm_sensors at all.

 I do agree that lm_sensors may be a a start since it has a detection
 tool.  Then he could take that info and dig around in the kernel config.

[gentoo-user] Pentium D Temperature and Frequency Scaling

[Richard McCombie]

Hi,

I'm trying to monitor the temperature of my CPU in Gentoo. I have a
Pentium D 3.00GHz.

I tried compiling my kernel with the coretemp module but this won't
modprobe (which, I imagine, is because the module is exclusively for
Core chips).


Also, I have CPU frequency scaling set up (using the ACPI Processor
P-States driver). I have a minimum frequency of 240 and a maximum
frequency of 300 - both of these were present by default. My PC
correctly switches between the lower and upper frequencies depending
on how busy the machine is (using the ondemand governor) but I would
like to know whether there should be any lower frequencies in the
'scaling_available_frequencies' file; 2.4GHz seems a little high as a
minimum frequency.


Thank you in advance,
Richard
