Dear Maintainer,

it appears cpufreq-info has issues with a lot of CPUs?

No cpu31 here either. So maybe it is a kernel bug of some sort.

Thanks.

PS. The 'current CPU frequency' is not correct anyway, it should be 3.94
/ 3.97 as read by `cpufreq-info -f`, and other sources
(mate-sensors-applet, /proc/cpuinfo, lscpu, etc).

cpufrequtils is unmaintained upstream and is in the archive essentially
only because its replacement is missing some functionality (IIRC).

Could you install linux-cpupower and try
  cpupower -c all frequency-info
?

Ha! Yes, most likely an issue on the kernel end.
I'm reassigning to linux-image4.18.

Same issue, last CPU has missing info.

Thanks.

Missing file in sys indicate it is an issue with kernel or my
motherboard / CPU.

I might be missing something, but ...

0 - 31 means a count of 32.  Or do you have more than 32?

I have 16 cores, 32 threads.

It only shows correctly first 31 CPUs. (cpu0 to cpu30). Last one cpu31 is
missing some data.

(I sent this before, but for some reasons it didn't get into bts.)


I have 32 cpus. So cpus indexed 0 - 31. Yes.

* the cpu 0 - 30 show correct power/frequency info.
* cpu 31 doesn't.

Please inspect carefully my attached outputs of the tools used.

So it only works for 31 CPUs, as in the subject.


Thanks!
