lm_sensors nothing detected [solved]

[musv]

Hi,

according to this tutorial I wanted to install lm_sensors for monitoring the hardware sensors.

First of all my config:
Motherboard: A-N68SV (MCP68S)
CPU: Athlon 64 X2 6000+
Kernel: Gentoo-sources 2.6.28-r1 (64bit installation)

Problem:
1. I don't get an i2c-device. I compiled i2c-dev as module. It loaded perfectly. In the logs I find this message:

[energyman76b]

I don't know, you didn't post your .config.
Which would be a nice start.

ok, here you are:

[energyman76b]

hm, apart from some little things (paravirt? slub debug?) your config looks ok. Is udev running? Have you upgraded udev to the latest version?

I found [a|the] solution. I started gkrellm and the sensors (except of hddtemp) worked. The k8temp-module was loaded. Ok, the temperatures seem not really correct: According to gkrellm the 2 cores have a temperatures of 12°C.

The solution is:
You simply don't need lm_sensors.

The support for Paravirtualized Guest system I had enabled because of the nvidia-drivers, that probe if it's enabled. Maybe VMWare could benefit, were my thougths.

[energyman76b]

you need the right sensors for:
fan speed
voltages
temps besides the on chip diods

That the temps given out by k8temp are almost always wrong is a known bug. Open for ages.

edit:
CPU Fan: 231 RPM (min = 0 RPM, div = 32)
Sys Temp: +35°C (high = -5°C, hyst = +125°C) [thermistor]
CPU Temp: +50.5°C (high = +80.0°C, hyst = +75.0°C) [thermistor]
AUX Temp: +49.5°C (high = +80.0°C, hyst = +75.0°C) [thermistor]


k8temp-pci-00c3
Adapter: PCI adapter
Core0 Temp:
+38°C
Core1 Temp:
+38°C

Hmm, ok. Sounds logical. Then I'm again on the start problem, where I didn't find a suitable sensor.

[energyman76b]

turn on this:
# CONFIG_SYSFS_DEPRECATED_V2 is not set

I have:
CONFIG_SYSFS_DEPRECATED=y
CONFIG_SYSFS_DEPRECATED_V2=y

and obviously no problems with sensors

Thx, finally it works. If anyone else has these problems, here's a short summary:

1. Activate in kernel:

[thom_raindog]

Glad you got it worked out..
I found your thread because I have the same sensors, according to lm_sensors.
Unfortunately the module k8temp was not "installed" when I ran sensors-detect, even though I had activated every item under I2C and hardware monitoring in my kernel config.

Can you point me to the right thing to add to my config to make that work?

[energyman76b]

/etc/conf.d/lm_sensors
MODULE_0=w83627ehf
MODULE_1=k8temp

That's what mine reads too, thank you
But sensors-detect complained that k8temp was "not yet installed" and not very much of a surprise there is no k8temp loaded according to lsmod.
Restarting lm_sensors shows [!!] for k8temp, which probably is supposed to point out that the modules cant be loaded.
The lm_sensords website specifically mentiones that there are problems with the k8temp module on certain kernels.

Hence the question: How did you configure your kernel for the k8temp module to show?

[energyman76b]

just the usual, i2c support, i2c device interface m, autoselect pertinent helper modules *, i2c hardware bus support, Intel PIIX4 and compatible (ATI/Serverworks/Broadcom/SMSC) m (hava amd chipset), Hardware Monitoring support m, AMD Athlon64/FX or Opteron temperature sensor m

I must be blind or dumb, I can't find anything that seems to have to do with an AMD X2 chip and temperature.. Your stuff was not exact enough for a newbie

[energyman76b]

cd /usr/src/linux
make menuconfig
Device Drivers --->
<M> I2C support --->
<M> I2C device interface
[*] Autoselect pertinent helper modules

I2C Hardware Bus support --->
M> Intel PIIX4 and compatible (ATI/Serverworks/Broadcom/SMSC)
(and whatever else you have as chipset)

back under Device Drivers:
<M> Hardware Monitoring support --->
<M> AMD Athlon64/FX or Opteron temperature sensor

OK, so I am NOT dumb or blind. It's just not there....
What kernel version are you using? I am on 2.6.29-r1.

[energyman76b]

2.6.28.X

haven't tried 2.6.29 so far. But I do have the .29 sources installed - and it is in the exact same place in menuconf.

You know about the search feature (/)?

Thanks, I didn't know that.
Indeed, k8temp SHOULD be there, but it isn't. Now, reading the description (thanks to the search feature) it depends on:
HWMON && X86 && PCI && EXPERIMENTAL
I got the hwmon thing down. Does X86 mean it will not be available on my x86_64 system?
And what about Experimental?...
Ah, experimental it was..
Thank you for your patient help

[energyman76b]

x86 and x86_64 is the same - fpr the kernel. They merged both architectures a while ago.
