hwmonX not available

[pedro2555]

Description

I've installed via the provided ubuntu_dkms_sudo_install.sh script. One weird thing is it didn't request for elevated permissions. Aparently all went ok.

Running sensors does give some new outputs.

$ sensors
asus-isa-0000
Adapter: ISA adapter
cpu_fan:     25500 RPM
temp1:        +38.0°C  

asus_fan-isa-0000
Adapter: ISA adapter
CPU Fan:     4813 RPM  (min =   10 RPM, max =  255 RPM)
GFX Fan:     6978 RPM  (min =   10 RPM, max =  255 RPM)
gfx_temp:         N/A  (crit =  +0.1°C)

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +39.0°C  (high = +100.0°C, crit = +100.0°C)
Core 0:        +37.0°C  (high = +100.0°C, crit = +100.0°C)
Core 1:        +37.0°C  (high = +100.0°C, crit = +100.0°C)

Where previously only the coretemp-isa-0000 section was available.

But the hwmonX thing is not available.

/sys/class/hwmon$ ls
hwmon0  hwmon1  hwmon2  hwmon3  hwmon4  hwmon5  hwmon6  hwmon7  hwmon8

The Machine

It is a UX303UB, and is currently facing an issue where the fan is always at full speed. From post.

can you please check with lsmod whether the asus-fan module is loaded, if yes please also post your dmesg output that is related to asus-fan loading, you might rmmod asus-fan and then modprobe asus-fan in order to see the initialization of asus-fan at the end of the dmesg log...

[pedro2555]

The module is loaded.

$ lsmod | grep asus
asus_nb_wmi            28672  0
asus_wmi               32768  1 asus_nb_wmi
sparse_keymap          16384  1 asus_wmi
asus_wireless          20480  0
asus_fan               16384  0
wmi                    32768  2 asus_wmi,mxm_wmi
video                  49152  2 asus_wmi,i915

Here is the output you asked for. Sounds like something is wrong indeed. Again, remind you this unit currently has an issue where the fans are always at 100% (highly supect an hardware issue), would be good to fix it via software.

dmesg | grep asus-fan

but this looks like the hwmon device was created: [ 15.787325] asus-fan (init) - created hwmon device: hwmon6

please check /sys/class/hwmon6 for its contents, best case post the output of the following line while inside the hwmon directory: for a in *; do echo $a $(cat $a); done

another option you have is to force_load the module to see if this changes anything (as described within the README

and digging even deeper your can try using the test_module.sh and acer_ec.pl scripts to be found in the misc directory...

Oh. Ok, I see. That was a miss understanding from my part.

Thanks for the help. Everything looks fine indeed, I was just unsure about the exact path after all.

I don't seem to be able to control the fans, but that is probably another issue.
