| If you have an IBM Thinkpad (any model), do NOT use lm_sensors under any circumstances. |

Hey!
This info is great!.
I'm wondering if there is a app out there that can output the sensors info to web?
The ones I found doesn't support my chip (amd756). |

If you get this error message:
#sensors-detect
#No i2c device files found. Use prog/mkdev/mkdev.sh to create them.
Download the source, untar it. And run the mkdev.sh script to create the necessary device files in order to let sensors-detect do its job.
Perhaps a change in the ebuild??
Hope this helps.

Making It Work
When compilling your kernel in the Character Devices section enable I2C Support , I2C device interface, and I2C /proc interface, as modules. If you have a tvtuner card, like I do, you already have probably already enabled these options. If you haven't already enabled them all you have to do is:
| Code: | | # make modules && make modules_install |
After compilling your kernel do the following
| Code: | | emerge i2c lm-sensors gkrellm |
|
If I recompile my kernel, do I have to re-emerge i2c lm-sensors and gkrellm? If so it would be like for alsa-driver.
Thanks!

Followed your guide. 2.8.1 wouldn't give me any temperatures, so I unmerged and emerge 2.8.2 and there it was. Thanks. I've always installed from the vanilla sources rather than emerge, but for some reason the "make, make install..." method wouldn't work this time. At least portage was there to bail me out.

|
|
Good news for you (and me), berus. It is right that you do not need the p4b_smbus module anymore. The Intel 801 (i2c-i801) option enabled in the kernel works for my Asus P4B533E mb with the ASB100 hardware monitoring chip which is supported in the 2.6.3 kernel (wasn`t so in the 2.6.1 kernel, had to upgrade).
All i did was enable:
the Intel 801 option in Device Drivers--> I2C support --> I2C Hardware Bus support;
the I2C device interface option in Device Drivers--> I2C support;
the Asus ASB100 Bach option in Device Drivers --> I2C support --> Hardware Sensors Chip support.
The modules i have to load are asb100, i2c_sensor, i2c_i801, i2c_dev and i2c_core, which i have also added to to my /etc/modules.autoload.d/kernel-2.6 file. If I also have to do the rc-update add lm-sensors default I do not know. But I get the right temperature out of the box.
Bye, Valentin. |

I think rollinncoaster is wrong, at least in my case. When I get this message its because I haven't loaded i2c-dev yet. |

CPU fan speed is always zero.
I have a 3 pin connector to the CPU fan, as the document suggests, but the speed shown is always zero.
The system fan speed indicator is working though. |

The sensors-detect utility identified that I need a module named bmcsensors.
| Code: | #----cut here----
# I2C adapter drivers
modprobe i2c-piix4
modprobe i2c-isa
# I2C chip drivers
modprobe eeprom
modprobe bmcsensors
# sleep 2 # optional
/usr/local/bin/sensors -s # recommended
#----cut here----
|
When I tried to install the module I get this. | Code: | modprobe: Can't locate module bmcsensors
|
I have searched the entire file system and cannot find an module named bmcsensors.o. All of the other modules installed and appear to work fine.
Here is what I get when I run sensors:
| Code: |
eeprom-i2c-0-50
Adapter: SMBus PIIX4 adapter at 08a0
Algorithm: Non-I2C SMBus adapter
Memory type: SDR SDRAM DIMM
Memory size (MB): 1024
eeprom-i2c-0-51
Adapter: SMBus PIIX4 adapter at 08a0
Algorithm: Non-I2C SMBus adapter
Memory type: SDR SDRAM DIMM
Memory size (MB): 1024
|
Is there a workaround or solution for this? |

Why's that?! |
Because it can corrupt the eeprom on certain (most?) Thinkpads.

Ensure that you have the source available again, by typing:
| Code: | | emerge -f lm-sensors |
Then, extract the mkdev.sh file from the archive by issuing the following command, while located for example in the /tmp directory:
| Code: | | tar zxvf /usr/portage/distfiles/lm_sensors-2.8.1.tar.gz lm_sensors-2.8.1/prog/mkdev/mkdev.sh |
You'll find mkdev.sh in /tmp/lm_sensors-2.8.1/prog/mkdev/mkdev.sh

hi all!
i am running a a-xp 2400+ on my gigabyte ga7dxr with a ekl-papst cooler.
this is what lm-sensors tells me:
| Code: |
via686a-isa-6000
Adapter: ISA adapter
Algorithm: ISA algorithm
CPU core: +1.81 V (min = +1.79 V, max = +2.18 V)
+2.5V: +1.13 V (min = +2.24 V, max = +2.74 V) ALARM
I/O: +3.30 V (min = +2.95 V, max = +3.62 V)
+5V: +4.99 V (min = +4.47 V, max = +5.49 V)
+12V: +12.28 V (min = +10.79 V, max = +13.18 V)
CPU Fan: 0 RPM (min = 3000 RPM, div = 2)
P/S Fan: 0 RPM (min = 3000 RPM, div = 2)
SYS Temp: +61.0°C (limit = +60°C, hysteresis = +50°C) ALARM
CPU Temp: +37.4°C (limit = +60°C, hysteresis = +50°C)
SBr Temp: +25.3°C (limit = +60°C, hysteresis = +50°C)
|
1. why is there a error with the Voltage?????
2. the cpu temp is about 50° not 37 nor 61° !!!!!!! why is it so far off (and / or wrongly labeled?)
thanks!

| Posted: Thu Aug 19, 2004 1:35 pm Post subject: solution to sensors-detect complaining about no i2c devices |
|
|
I've got a dual Xeon 2.4Ghz and I've unsuccesfully tried to make lm-sensors work a lot of times. I always arrived to the following message:
| Code: |
# modprobe i2c-dev
# sensors-detect
No i2c device files found. Use prog/mkdev/mkdev.sh to create them.
|
And I had no clue on how to continue from here. (Using mkdev seemed a bit out of place). Every howto I've read proposes, as it is shown in the example, to just load the module i2c-dev prior to the execution of sensors-detect to solve this problem.
But, with my machine (or kernel configuration) this was not sufficient.
I've just found that I also needed to load the i2c-isa module prior to running sensors-detect (I've double-checked that this was the only aditional module needed). This solved the problem:
| Code: |
# modprobe i2c-dev i2c-isa
# sensors-detect
[output of sensors-detect]
|
Perhaps it is usefull to add this information to the how-to.
Thank you very much for your effort. |

|

Hi,
it seems like many times it is easyer to read than to execute.
I am not able to enable lm-sensors.
This is what I get when I run sensors-detect
No i2c device files found. Use prog/mkdev/mkdev.sh to create them.
Moreover, I am not able to find in my kernel this entry: <M> I2C /proc interface Where is it???
Finally, if I run sensors I get: | Code: | # sensors
Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and done
'modprobe i2c_sensor'!
For older kernels, make sure you have done 'modprobe i2c-proc'!
|
Here is my configuration spec:
- 2.6.9-gentoo-r13
- Udev
- Kernel specs:
| Code: | <M> I2C support
<M> I2C device interface
I2C Algorithms --->
I2C Hardware Bus support --->
Hardware Sensors Chip support --->
Other I2C Chip support --->

Please help. I am tired reading here and there info and tips but not having mine working. 
Thank you,

this guide is more than 2 years old, probably many things have changed since then.
I never could lmsensors get working, no matter what i did, so, for the moment, i li´ve with gkrellm2 which shows me CPU and GPU Temps out-of-the-box. |

I got it to work, this is what you need to do:
(This tutorial was made using a 2.6.12 kernel, most recent versions of the 2.6 kernel have /proc support for I2C built in so enabling it is unnecissary.)
Step One - Kernel
First, configure your kernel with i2c and i2c-dev compiled as modules.
| Quote: |
Device Drivers ---> I2C support ---> (M) I2C support
Device Drivers ---> I2C support ---> (M) I2C device interface
|
After enabling them as modules, enable your corresponding I2C Hardware Bus support.
| Quote: |
Device Drivers ---> I2C support ---> I2C Hardware Bus support ---> (M) <coresponding module(s)>
|
Exit, saving your kernel config, then mount your /boot partition (if applicable) and compile your kernel.
| Quote: |
# make && make modules modules_install install
|
Reboot to your new kernel.
Step Two - Detection
At this point, install the lm_sensors package.
Now use modprobe to load all of the modules you enabled in the kernel.
| Quote: |
# modprobe i2c-core
# modprobe i2c-dev
# modprobe <corresponding hardware bus module(s)>
|
At this point its time to detect your heat sensors, run sensors-detect while answering "YES" to everything until you get to the summary question.
If this command fails, you either didn't follow this tutorial correctly, or chose the wrong I2C Hardware Bus support module.
Pressing enter, take note of all the modules listed that say "should be inserted" ignoring all other types. (You will use these later.)
| Quote: |
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `w83781d' (should be inserted):
Detects correctly:
* ISA bus address 0x0290 (Busdriver `i2c-isa')
Chip `Winbond W83782D' (confidence: 
Driver `via686a' (should be inserted):
Detects correctly:
* ISA bus, undetermined address (Busdriver `i2c-isa')
Chip `VIA Technologies VT82C686 Integrated Sensors' (confidence: 9)
|
Afterwards, allow the script to create the configuration file when it asks.
Using the notes you took enable the corresponding modules in your kernel.
| Quote: |
Device Drivers ---> I2C support ---> Hardware Sensors Chip support ---> (M) <your noted module(s)>
|
Your almost done! Rebuild your kernel with the previous build command (# make && make modules modules_install install) after mouting your /boot partition (if applicable).
Then enable the lm_sensors module autoloader.
| Quote: | | # rc-update add lm_sensors default |
*Then reboot to your new kernel.*
Test your sensors with the "sensors" command in the console.
Step Three - Choose Your Favorite Monitor
If your using KDE, then there is a KSensors applet you can install.
Otherwise, if your using Gnome or other window systems, install gkrellm.
And if your a console only advocate, simply use the "sensors" command provided with the lm_sensors package.
