cpupower and 4.12.X kernel

[Sandro]

Dearest, I know the service "cpupower" with the kernel

ci4771ht ~ # uname -a

Linux ci4771ht 4.12.5-gentoo # 1 SMP PREEMPT Fri Sep 1 23:40:33 CEST 2017 x86_64 Intel (R) Core i7-4771 CPU @ 3.50GHz GenuineIntel GNU / Linux

mistake me, that is:

cpupower | * Running cpupower -c all frequency-set --governor ondemand ... [!! ]

cpupower | * ERROR: cpupower failed to start

 

I would like to have some explanation, if perhaps cpupower is "deprecated" or how to configure kernel (with previous version everything worked perfectly).

 

Thanx for any suggestion.

rc-update add cpupower default

Then i ask about frequency using in a terminal

watch cpupower frequency-info

cause

ci74771ht ~ # /etc/init.d/cpupower start
cpupower           | * Caching service dependencies ...                                          [ ok ]
cpupower           | * Running cpupower -c all frequency-set --governor ondemand ...             [ !! ]
cpupower           | * ERROR: cpupower failed to start

my kernel is

Linux ci74771ht 4.12.5-gentoo #1 SMP PREEMPT Tue Sep 5 00:07:21 -00 2017 x86_64 Intel(R) Core(TM) i7-4771 CPU @ 3.50GHz GenuineIntel GNU/Linux

with older versions of kernel, i don't had enabled the Intel P-state.

now with this kernel is enabled by default an is not possible to change it.. (excuse my bad US lang :|

thanx for the aid :)
