Trouble? Contact listmaster@lists.debian.org | > | | Got hardware sensors working on a few motherboards here and even | took notes on how it was done. Perhaps these notes might be useful to you. | | Notes on Installing sensor support in a Debian system. | | 0) For the following, it is assumed that a new | 2.4.20 kernel was already compiled, installed and | working. It is also assumed that the kernel was compiled | using the debian kernel build system make-kpkg. The | kernel source should be in /usr/src/linux either directly | or by a symbolic link. | | 1) have a working 2.4 series kernel with module support | included. Make sure that i2o items are NOT compiled | in. Once this kernel is installed and working, the modules | are ready to be included. Make sure you are running | the kernel to which the modules are to be added. This | seems to be the easiest way to make the module version | numbers consistent with the kernel version number. | | 2) obtain the debian packages: i2c-source,lm-sensors, | lm-sensors-source, and sensord. Optionally also | get other monitors like sensor-sweep-applet, | wmsensors or xsensors. The package xsensors is | not in woody but getting the source and building | it locally using apt-get source works fine. | | 3) Become root and change to the /usr/src directory. | In this directory there will be tar files named | i2c.tar.gz and lm-sensors.tar.gz. When these | tar files are expanded they write themselves | into the /usr/src/modules directory. This | directory may already exist if other modules | have already been installed in this kernel. | | 4) Extract the files by "tar zxf i2c.tar.gz" and | "tar zxf lm-sensors.tar.gz" | | 5) cd /usr/src/linux and run the command | "make-kpkg modules_image" | When the build has completed there will be | debian packages in /usr/src named | i2c-2.4.19_2.6.5-3+lb.custom.1.1_i386.deb | and | lm-sensors-2.4.19_2.6.4-3+lb.custom.1.1_i386.deb | | 6) install these packages with the commands | dpkg -i i2c-2.4.19_2.6.5-3+lb.custom.1.1_i386.deb | and | dpkg -i lm-sensors-2.4.19_2.6.4-3+lb.custom.1.1_i386.deb Sorry, this error messages appaers on the install of this i2c package : dpkg: dependency problems prevent configuration of i2c-2.4.20: i2c-2.4.20 depends on kernel-image-2.4.20; however: Package kernel-image-2.4.20 is not installed. dpkg: error processing i2c-2.4.20 (--install): dependency problems - leaving unconfigured Errors were encountered while processing: i2c-2.4.20 ?? This kernel is installed ! Compiled and installed by myself. (with the old method) What has I do other ? mess-mate | | 7) As root (as always) run the program sensors-detect. | This tool sweeps the smbus and determines the devices | that are on it. It then reports the chip types and | the relevant modules that need to be loaded to get the | hardware sensors system working. This program mostly | works but does not always work. See the last step for | suggestions if the modules were detected incorrectly. | | 8) Cut and paste the results from sensors-detect into | the relevant files as it requests. For one motherboard | as an example, | the lines: | # I2C adapter drivers | i2c-viapro | # I2C chip drivers | w83781d | have to be pasted into the file /etc/modules. | Then the command update-modules has to be run. | Then paste the lines | # I2C module options | alias char-major-89 i2c-dev | into the file /etc/modutils/local | | Then run the command /etc/init.d/modutils | | 9) After these steps are completed, the required | modules will be loaded. This can be checked by | the output of the lsmod command. The output for | this example is | Module Size Used by Tainted: P | w83781d 19224 0 (unused) | i2c-proc 6416 0 [w83781d] | i2c-viapro 3860 0 (unused) | i2c-core 15052 0 [w83781d i2c-proc i2c-viapro] | | 10) Then reboot the system. If the module system | is working correctly then after boot the loaded | modules should be identical to the previous output | of lsmod | | 11) To verify that the kernel interface is correctly tied | to the hardware run the command "sensors" | Typical output in this example is | w83782d-i2c-0-2d | Adapter: SMBus Via Pro adapter at e800 | Algorithm: Non-I2C SMBus adapter | VCore 1: +1.77 V (min = +1.74 V, max = +1.93 V) (beep) | VCore 2: +2.51 V (min = +1.74 V, max = +1.93 V) (beep) | +3.3V: +3.32 V (min = +3.13 V, max = +3.45 V) (beep) | +5V: +5.07 V (min = +4.72 V, max = +5.24 V) (beep) | +12V: +12.46 V (min = +10.79 V, max = +13.19 V) | -12V: -12.29 V (min = -13.21 V, max = -10.90 V) | -5V: -5.45 V (min = -5.26 V, max = -4.76 V) | V5SB: +0.13 V (min = +0.13 V, max = +0.13 V) | VBat: +0.08 V (min = +0.08 V, max = +0.08 V) | fan1: 0 RPM (min = 3000 RPM, div = 2) (beep) | fan2: 0 RPM (min = 187 RPM, div = 32) (beep) | fan3: 0 RPM (min = 3000 RPM, div = 2) | temp1: +32°C (limit = +60°C) sensor = thermistor (beep) | temp2: +33.5°C (limit = +60°C, hysteresis = +50°C) sensor = thermistor (beep) | temp3: +255.5°C (limit = +60°C, hysteresis = +50°C) sensor = 3904 transistor | vid: +1.850 V | alarms: | beep_enable: | Sound alarm disabled | | It is pretty important to confirm these values by comparing | them to the readings that the BIOS reports. If the numbers | match all is well. If the numbers dont match then you have | problems. One possibility is that the sensors-detect | program detected the wrong kind of hardware. Confirm what the | detected hardware matches the motherboard type. If the hardware | is correct confirm that the correct hardware module type is | enabled in the file "/etc/sensors.conf". This file controls the | translation from hardware digital numbers to human readable | floating point numbers. This file is heavily documented and | modifying it should be self-explanatory. | | 12) At this point the hardware sensor system is operational | and higher level tools like xsensors can be run. If the | output is correct then the interface to /proc/sys/dev/sensors | is also working | | 13) The highest level routines like sensord, ksensors, wmsensors, or | sensor_sweep_applet can now be configured to run as desired. | | 14) One some (maybe many motherboards) the above is sufficient | to get things working. But I had a couple of motherboard | types that failed in different ways. | | On one motherboard sensors-detect correctly detected | the hardware but on this motherboard (Asus P5A) the smbus is | known to be broken but the isa bus works and the hardware can | be accessed from there. Googling for "lm sensors Asus P5A" | led right to the lm sensors documentation which explained | that the problem is known and the workaround is to use the | isa bus. No explanation given as to how to do that. More | searching and tinkering led to the answer of putting the module | i2c-isa into the /etc/modules file. Then things started working. | | On another motherboard, (Gigabyte 7ZMMH) sensors-detect reported | the wrong hardware. Here the solution was to determine the actual | hardware on the motherboard. I found the site | http://mbm.livewiredev.com/ | to be helpful here. Then googling for combinations of the motherboard | hardware chipset and lm sensors led to a page where someone | kindly listed the modules required for this to work. After making | this change everything started working | | HTH | Cheers | | | | -- | To UNSUBSCRIBE, email to debian-user-request@lists.debian.org | with a subject of "unsubscribe". Trouble?
