 Posted: Fri Dec 17, 2010 9:04 pm Post subject: lm_sensor & pwmconfig |
 |
|
Hello to all,
i installed gentoo for restart a old brick notebook and use it like a server.
But, i've a problem: the fan are going at max speed ever..
So i emerged lm_sensors package for try to set the and launched sensors-detect:
| Code: | # sensors-detect revision 5861 (2010-09-21 17:21:05 +0200)
# System: Hewlett-Packard HP Pavilion dv2500 Notebook PC (laptop)
# Board: Wistron 30CE
This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no):
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No
AMD K8 thermal sensors... No
AMD Family 10h thermal sensors... No
AMD Family 11h thermal sensors... No
Intel Core family thermal sensor... Success!
(driver `coretemp')
Intel Atom thermal sensor... No
Intel AMB FB-DIMM thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no):
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no):
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no):
Using driver `i2c-i801' for device 0000:00:1f.3: Intel 82801H ICH8
Module i2c-dev loaded successfully.
Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `coretemp':
* Chip `Intel Core family thermal sensor' (confidence: 9)
Do you want to overwrite /etc/conf.d/lm_sensors? Enter s to specify other file name?
(yes/NO/s):
If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones! You really
should try these commands right now to make sure everything is
working properly. Monitoring programs won't work until the needed
modules are loaded.
Unloading i2c-dev... OK |
sensors:
| Code: | coretemp-isa-0000
Adapter: ISA adapter
Core 0: +68.0 C (high = +100.0 C, crit = +100.0 C)
coretemp-isa-0001
Adapter: ISA adapter
Core 1: +68.0 C (high = +100.0 C, crit = +100.0 C) |
the notebook is unboxed with all needed air flow and cpu work all time at 0% so, why this temperatures ?
pwmconfig:
| Code: | # pwmconfig revision 5857 (2010-08-22)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.
We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.
/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed |
Sufring on the web i understand the problem can be one missing module for have pwm working, but, how can i know which is the correct module ?
Notebook is a Hewlett-Packard HP Pavilion series dv2500.
Thanks for all |

I know this post is very old, but anyways try lsmod on distros with (almost) complete modules (e.g. Ubuntu)
Then: copy /lib/firmware/blahblahblah AND/OR /lib/modules/{kernel ver}/*something i cant remember* to your beloved Gentoo partition.
I've got this EXACT situation too (/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed) on an HP workstation. Tried modprobing i2c-core and NOT FOUND... but I can modprobe coretemp after building kernel modules (3.10.7-gentoo-r1)
lm-sensors only show a few line of temps and the fan is AMAZINGLY noisy while emerging. I mean VERY.
Hope this helps. Cheers 
What I've Did So Far:
| Code: |
pankung panpjp # sensors-detect
# sensors-detect revision 6085 (2012-10-30 18:18:45 +0100)
# System: Hewlett-Packard HP dx2310 MT(VP534PA)
# Board: Hewlett-Packard 0B10H

Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): y
# DMI data unavailable, please consider installing dmidecode 2.7
# or later for better results.

Done.
You should now start the lm_sensors service to load the required
kernel modules.
