#189329 — Is it possible to have temperature and fan speed readings on modern hardware?

[Multipart message — attachments visible in raw view] — view raw

Hello everyone.

The goal I trying to accomplish is to have full temperature monitoring
and speed control of PWM fans.
I have somewhat modern hardware. Here is partial output from
"sensors-detect" (lm-sensors package):
    $ sudo sensors-detect
# sensors-detect revision 6284 (2015-05-31 14:00:33 +0200)
# System: Gigabyte Technology Co., Ltd. H170-HD3 [Default string]
# Board: Gigabyte Technology Co., Ltd. H170-HD3-CF
# Kernel: 4.13.0-0.bpo.1-amd64 x86_64
# Processor: Intel(R) Core(TM) i5-6600 CPU @ 3.30GHz (6/94/3)
Some south bridges, CPUs or memory controllers contain embedded sensors.
...
Intel digital thermal sensor...                             Success!
    (driver `coretemp')
...
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): y
Probing for Super-I/O at 0x2e/0x2f
...
Trying family `ITE'...                                      Yes
Found unknown chip with ID 0x8628
...
Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices.
...
Found unknown SMBus adapter 8086:a123 at 0000:00:1f.4.
Sorry, no supported PCI bus adapters found.
...
Now follows a summary of the probes I have just done.

Driver `coretemp':
  * Chip `Intel digital thermal sensor' (confidence: 9)

What could be done about "unknown chip" devices?
For now "sensors" command output is:
    $ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +27.8°C  (crit = +119.0°C)
temp2:        +29.8°C  (crit = +119.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Package id 0:  +27.0°C  (high = +84.0°C, crit = +100.0°C)
Core 0:        +23.0°C  (high = +84.0°C, crit = +100.0°C)
Core 1:        +24.0°C  (high = +84.0°C, crit = +100.0°C)
Core 2:        +22.0°C  (high = +84.0°C, crit = +100.0°C)
Core 3:        +22.0°C  (high = +84.0°C, crit = +100.0°C)

I'm assuming these coming from "coretemp" kernel module, the only thing
"lm-sensors" recognized, but there is no Fan related information.

Is it possible to have temperature and fan speed readings on modern
consumer-grade hardware?
Is there a replacement for outdated and possibly dead "lm-sensors" project?
Maybe there is some monitoring Nagios-like system where its agents don't
depend on "lm-sensors" package?

Who knew it is simple like that.

I wonder now if I should file a bug on "lm-sensors" package for not
trying to "modprobe it87" during execution of "sensors-detect" script
and scare people off with bogus "unknown chip" messages...

Anyway, thanks for help.

The last time I looked at this it was harder, but things have gotten 
better with newer kernels so it actually works in a straightfoward 
fashion now. It's on my todo list to figure out whether this is 
something that works upstream but not in debian or something that needs 
to be fixed in the detect script and file the appropriate bugs. (But if 
someone else wants to do it first, I won't be mad. :) )
