HI,

Still updateing/configuring/correcting/completing my new PC...

This time it is the sensors readout via 'glances'

My setup:
AMD Ryzen 5 2600. MSI Tomahawk Max, NVidia RTX 3600 SUPER
Kernel 5.6.11 vanilla
sys-apps/lm-sensors 3.6.0 

Beforehand I did a sensors-detect and answered every item with
"yes".

This is the final result:
|    Driver `k10temp' (built-in):
|      * Chip `AMD Family 17h thermal sensors' (confidence: 9)
|    
|    Driver `nct6775' (built-in):
|      * ISA bus, address 0xa20
|        Chip `Nuvoton NCT6797D Super IO Sensors' (confidence: 9)
|    
|    No modules to load, skipping modules configuration.


The readout via 'glances' looks like this (the temps are higher than
idle...currently a massive update is running... :) :

fan1 and fan4 are not used, the readout is ok therefore. But PCH_* is
"0.0° C" as the other "???" marked values from above are.

On the internet I found descriptions of new formulas from the early
times of the Ryzen processors to correct existing readouts...but in
the case above, it seems, that there is no readout at all.

Are the lines marked with ??? "normal" or do I need some additional
configuring?

Cheers!
