Which version of lm-sensors (or pwmconfig) is this?

I would like to see the full output of pwmconfig and not just the above
summary.

Many boards can monitor the fans but not control them. What board is it?

I would be interested in the output of the following commands:

grep -H . /sys/class/hwmon/hwmon*/device/name
grep -H . /sys/class/hwmon/hwmon*/device/pwm*
ls -l /sys/class/hwmon/hwmon*/device/pwm*

nelis@nelis-desktop:~$ pwmconfig
# pwmconfig revision 5630 (2009-01-29)
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.

Found the following devices:
   hwmon0 is acpitz
   hwmon1/device is k8temp
   hwmon2/device is f71862fg

Found the following PWM controls:
   hwmon2/device/pwm1
   hwmon2/device/pwm2
   hwmon2/device/pwm3
There are no usable PWM outputs.

Hmm, you are root, aren't you?

Note that all 3 fan controllers are in automatic mode (pwm#_enable >
1), which is less CPU-intensive than manual mode and usually gives
better results. So you might now want to use pwmconfig and fancontrol
anyway, but rather tweak the automatic mode settings by writing to the
pwm#_auto_point# files above.

I admit the current configuration is a little odd. Usually point2 has
pwm and temperature values above point1, not below. I am not familiar
with the Fintek F71862FG and its driver though. Hans?

Yes, erm well the F718xx family has them in reverse order in hardware and
I kept the hardware order for sysfs files. A bit strange I must admit.

In hindsight it might have been better to reverse the order in sysfs
for consistency with other drivers.

Hans

I agree. It shouldn't be too difficult, and even though we can't easily
get a fully consistent interface for automatic speed mode due to each
chip being different in its own creative way, being as consistent as we
can makes things easier for the users.

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.

Found the following devices:
   hwmon0 is acpitz
   hwmon1/device is k8temp
   hwmon2/device is f71862fg

Found the following PWM controls:
   hwmon2/device/pwm1
hwmon2/device/pwm1 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as
it is more efficient and it reacts faster. Are you sure that
you want to setup this output for manual control? (n)
   hwmon2/device/pwm2
hwmon2/device/pwm2 is currently setup for automatic speed control.
In general, automatic mode is preferred over manual mode, as

So i guess temp3 is cpu temp and temp1 is motherboard temp.
But can't change that either.

OK, I'll change pwmconfig to complain if run as non-root.

Never mix sudo and shell redirection, it doesn't work. Redirection
"happens first" so you try to write as non-root, and this isn't allowed.

Or the other way around, it's hard to tell. Maybe looking at what the
BIOS displays will provide valuable hints. I certainly hope temp2 isn't
real...

Same problem as above. Use su instead of sudo. Or maybe sudo sh -c ...

Trading permission for invalid arguments. Sounds like politics.

Take a look at Documents/hwmon/f71882fg for which values are allowed,
with your chip only 1 (manual mode) and 2 (auto mode) are supported,
0 = pwm disabled (fans full speed) is not supported.

The pwm#_auto_channels_temp attributes are a bitmap, you are now asking
for both temp1 and temp2 to influence pwm1, the chip cannot handle this,
you need to choose one.

Yes, but do we want to change this now, after the fact, that would
basically come down to ABI breakage.

You can see it that way for sure. Or you can see it as fixing an
interface which was improperly implemented originally. While our
documentation doesn't explicitly say how trip points are ordered, the
"incremental" approach is the most natural one and the one implemented by
all other drivers too.

I don't care too much myself, so it's really up to you. You may also
want to contribute a patch to the documentation to make things clearer.
