Missing temperature for some threads

[somera]

I'm using self compiled 3.1.1 release.

On one computer I missing temperature for threads 5-8

In btop++ I see temperature for all cores

For the same CPU on other computer it's all fine

@somera: Can you please provide the sensors -u output?

I have two same NUCs. ;) On the one it's working. On the other not,

[somera]

$ lscpu | egrep 'Model name|Socket|Thread|NUMA|CPU\(s\)'
CPU(s):                          8
On-line CPU(s) list:             0-7
Thread(s) per core:              2
Socket(s):                       1

NUMA node0 CPU(s):               0-7

[The-going]

The important line in this:

Thread(s) per core: 2

4 physical processors - four temperature sensors. My chip (Intel(R) Core(TM) i7-2600K CPU @ 3.40GHz) has 5 sensors. One per CPU and one GPU. The built-in GPU is disabled and the temperature sensor is not visible for it. The plasmoid on the desktop shows this picture:

Most likely, we need to correctly display the readings of real physical sensors in a separate line, and not mix everything. I.e., for each individual CPU (real \virtual), show the loading slider and frequency, and put the temperature sensors in a separate group.

And now the same issue with the NUC where is works for threads 5-8 ;)

@somera: This seems to be depending on the sequence of sensors as detected by libsensors.
Can you confirm the sensors -u on that computer is different from the one you pasted in the #856 (comment) ?
