Hi all, looking for your kind expert advice yet again. Installed Slackware 13 64 bit a couple of weeks ago. Very impressed as usual, just keeps getting better and better.

Well a few issues so from the beginning. I installed conky from source and wish to get my cpu temps listed too. So did the sensors-detect stuff and basically said need to use it87 module and k10temp (not supported, officially so downloaded and installed the standalone driver from http://khali.linux-fr.org/devel/misc/k10temp/ ). K10temp loads with the 'force' option but when I try loading it87 I get the following errors in dmesg...

Code:

it87: Unknown symbol vid_from_reg
it87: Unknown symbol vid_which_vrm

Any ideas would be very much appreciated.

BasthTin.

PS: Merry Christmas :-)

You ran "modprobe it87" and gave you this error ?
According to grep in my box both symbols are aliased in modules.symbols
to hwmon_vid. If you ran modprobe it should load any dependent modules
automatically.

try the following

Code:

depmod -a
modprobe it87

and see if it works. If not try running "modprobe hwmon_vid" manually.

Thankyou so much imitheos. Worked like a dream. One question answered tends to lead to another un-answered. Now how do I find out what readouts relate to what hardware or can you help translate the output?

Code:

k10temp-pci-00c3
Adapter: PCI adapter
temp1:       +18.5°C  (high = +70.0°C, crit = +65.0°C)

it8718-isa-0290
Adapter: ISA adapter
in0:         +1.31 V  (min =  +0.00 V, max =  +4.08 V)
in1:         +1.94 V  (min =  +0.00 V, max =  +4.08 V)
in2:         +3.31 V  (min =  +0.00 V, max =  +4.08 V)
in3:         +4.08 V  (min =  +0.00 V, max =  +4.08 V)   ALARM
in4:         +3.02 V  (min =  +0.00 V, max =  +4.08 V)
in5:         +2.51 V  (min =  +0.00 V, max =  +4.08 V)
in6:         +0.10 V  (min =  +0.00 V, max =  +4.08 V)
in7:         +3.31 V  (min =  +0.00 V, max =  +4.08 V)
Vbat:        +3.06 V
fan1:       1130 RPM  (min =    0 RPM)
fan2:          0 RPM  (min =    0 RPM)
temp1:       +33.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp2:       +34.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermistor
temp3:       +35.0°C  (low  = +127.0°C, high = +127.0°C)  sensor = thermal diode
cpu0_vid:   +1.550 V

You need to modify /etc/sensors3.conf. Search for "it87" to find
the relevant section.

Unfortunately the values are specific to each motherboard model.
You can find more info of what to put in the following links:
http://www.lm-sensors.org/browser/lm...rature-sensors
http://www.lm-sensors.org/browser/lm...c/fan-divisors
http://www.lm-sensors.org/wiki/Configurations

The third link provides config files for some motherboards so you
can browse for your own or similar with the same chip.

My config for a Gigabyte P35-DS4 is the following:

Code:

label in0 "Vcore"
label in1 "Vram" # DDR 1.8 V
label in2 "+3.3V"
label in3 "+5V"
ignore in4
ignore in5
ignore in6
label in7 "+12V"
label in8 "Vbat"

compute in3 @*(6.8/10+1), @/(6.8/10+1)
compute in7 @*(30/10+1), @/(30/10+1)

label temp1 "NBr Temp"
label temp2 "CPU Temp"
ignore temp3

label fan1 "CPU Fan"
ignore fan2
ignore fan3
ignore fan4

In my case, Vcore is not the same as in BIOS or nominal value for
my CPU. Also i ignored some values as you see because i didn't know
what they were. I haven't found any definitive guide of what to put
in there. The compute lines are calculated according to resistance
values but i don't think any motherboard mentions what it uses in
some manual.

Try some configs from the 3rd link and see which gives you the most
sensible results.

Thanks for the links and advice, working on it now.
