Compiling lm-sensors in 2.6.31-19-generic kernel

[Mark_in_Hollywood]

The instructions for compiling an lm-sensors module into the kernel are

Copy the two files from:
http://khali.linux-fr.org/devel/misc/k10temp/
to a temporary directory, then run:
$ make
then as root:
# insmod k10temp.ko

I made a temporary folder: makelm. In it are the two files: one I named Makefile and the other k10temp.c.

Running make gave:

mark@Lexington-19-Karmic:~/Desktop/makelm$ make
make[1]: Entering directory `/usr/src/linux-headers-2.6.31-19-generic'
CC [M] /home/mark/Desktop/makelm/k10temp.o
Building modules, stage 2.
MODPOST 1 modules
CC /home/mark/Desktop/makelm/k10temp.mod.o
LD [M] /home/mark/Desktop/makelm/k10temp.ko
make[1]: Leaving directory `/usr/src/linux-headers-2.6.31-19-generic'

Then I did:

mark@Lexington-19-Karmic:~/Desktop/makelm$ sudo su

root@Lexington-19-Karmic:/home/mark/Desktop/makelm# insmod k10temp.ko

but when that ran, the terminal returned only:

root@Lexington-19-Karmic:/home/mark/Desktop/makelm#

The make lm now has 7 more files in it, but what do I do to complete the installation and get readings on my panel?





I have linux-headers and I believe all the other compiling software alrady installed.

Is there any specific reason why you want to compile lm-sensors? If not, just install it from Ubuntu's repositories...

install:

sudo apt-get install lm-sensors

configure:

sudo sensors-detect

...and test:

sensors

if the results seem strange, then edit /etc/sensors.conf to attach correct sensors for correct values, and if necessary, calculate the correct multipliers for readings and set sane min/max values.

What coems to the original problem, successfull commands usually don't give any response, errors do. So check if the module is already succesfully loaded by running "lsmod".

Read more carefully. He doesn't want to compile lm-sensors itself, but a sensors driver that is not shipped with the kernel in the repos.

good point, lucky thing I also answered to the module loading problem...

...and to continue that answer, if the module actually was succesfully loaded then just add it to /etc/modules to load it automatically on boot. You'll of course have to do sensors-detect and other configuration part to get lm-sensors to work correctly.

I"m confused by the output of sudo sensors-detect:

AMD K10 thermal sensors... Success!
(driver `to-be-written')
Intel Core family thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No

Now follows a summary of the probes I have just done.
Just press ENTER to continue:

Driver `to-be-written' (should be inserted):
Detects correctly:
* Chip `AMD K10 thermal sensors' (confidence: 9)

I will now generate the commands needed to load the required modules.
Just press ENTER to continue:

To load everything that is needed, add this to /etc/modules:

#----cut here----
# Chip drivers
# no driver for AMD K10 thermal sensors yet
#----cut here----

Do you want to add these lines automatically? (yes/NO)n
mark@Lexington-19-Karmic:~$

If lm-sensors detects the K10 module, what do I have to write to /etc/modules to get it up & running?

[Bachstelze]

The command

lsmod

will output a list of all loaded modules. In k10temp is in there, you can run

sensors

and you should see your sensors data.

[Mark_in_Hollywood]

mark@Lexington-19-Karmic:~$ lsmod
Module Size Used by

k10temp 3680 0

but when I

mark@Lexington-19-Karmic:~$ sensors
No sensors found!
Make sure you loaded all the kernel drivers you need.
Try sensors-detect to find out which these are.

Any ideas about this?

Did you test with the "lsmod" comamnd if your module loaded correctly when you ran the "insmod" command? If it did load, just add the name of the module to /etc/modules.

No, I had no sense that testing was needed. My problem is I have no idea of what the name of the module is. I have several files in my temporary directory where the compiling took place. Currently in /etc/modules the only driver is:

powernow-k8

the compiling only gave names like:

k10temp.ko
k10temp.c
k10temp.mod.c
k10temp.mod.o
k10temp.o

and

Makefile
Module.markers
Module.symvers
modules.order

that's all there is, so I have no file named:

powernow-k10 or similar.
