Corefreq: single print of a value

[LouisCyfer]

Hi, I don't know if it's just me or my lack of experience in utilizing bash-scripts.

I really love the idea of this tool and need itto have any idea about my CPU temperature (lm-sensors doesn't work well for my AMD Ryzen 2700).

I figured the option -C prints out a sensor monitor continuously. is there a way to make that one single-print so it can be used like grepping a value from sensors?

Hi

It is made to be continuous but I'm adding your idea into the todo list.

Meanwhile, you can use the JSON output, argument -j
There are a lot of data but piping through a json parser, you could limit the output to the temperature values. Those are mainly per CPU for each core.

Hello,

For your testings, the enhancement is available in the develop branch.

• Here is the new syntax:

corefreq-cli -h

• Going further, you can also combine various iterations

corefreq-cli -C 3 -V 2 -W 5

which means 3 Sensors loops, 2 Voltages loops, 5 Power loops

Thanks for any comment.

That is awesome, ty for the insight. This helps alot!

Have you checked sensors recently? The module k10temp, after some kernel updates, has added more and more, and now shows a lot of values for at least X570 and any Ryzen 3 CPU. A bit strange if it doesn't go for the 2XXX CPUs as well?

I get all this from my 3950X, ccds and everything:

Adapter: PCI adapter
Vcore:         1.48 V  
Vsoc:          1.08 V  
Tctl:         +35.4°C  
Tdie:         +35.4°C  
Tccd1:        +34.0°C  
Tccd2:        +37.5°C  
Icore:        14.00 A  
Isoc:          8.50 A

I don't discourage the use of CoreFreq of course. It's awesome 👍 But for simple grepping etc, just using the built-in kernel module is simpler.

NOTE: There's NO reason to run # sensors-detect. As long as k10temp loads at boot it just works, as with Coretemp for Intel.

Closing the issue.
As a reminder for anyone reading this: don't run any k10temp or any other sensors driver in the same time than _CoreFreq_. This will overwhelm the SMU of Ryzen, EPYC, Threadripper processors which may freeze sooner or later.
