[SOLVED] CPU frequency Applet

[sirlitoldo]

Dear, sorry for my english: I upgrade mint 17.1 up to mint 17.2 and now this applet do not work (show the frequency but do not able to change the frequency). Before the upgrade this applet work really well and was very helpfull!!! PLS BE SO KIND TO HELP ME IN ORDER TO SOLVE THIS MATTER.

Scaling governor applets are deprecated for new Intel processors starting with SandyBridge processors onward. You were using the old Acpi driver governor designed for early cpufreq capable processors many years ago.

Your cpu is SandyBridge architecture. Now processors implements their own scaling policy, they manage running frequency and power consumption on their own. The new user space driver interface is called intel pstate, Ubuntu used to disable pstate for some reasons hence allowing the use of deprecated driver for your cpu. Only Performance and Powersave governors are now available to user space, powersave governor now means leaving the cpu's own policy decides cpu throttle. Basically trying to force the old behavior is non sense, that's why old driver is now no more available.

[sirlitoldo]

Understood, so in your opinion no solution to return back to ACPI? or not safe?
but last question:
may I manage the default status between Performance and/or Powersave, or the governor decide upon me!!!
If I can mange, how to do it?
Thks again Laurent

[Laurent85]

Hi sirlitoldo,
I would not recommend to force the old driver since it was designed for now old cpu's with different capabilities, I don't know about the consequences.

I manage the default status between Performance and/or Powersave

I think that if you select Performance the cpu always run at top frequency, using default Powersave governor the processor uses it's internal own policy for cpu throttle, I mean at the hardware level, you can't manage it at the user level. Things that do work are for example using cpufreq tools to cap top frequency to a lower level when throttling, or disabling turbo boost. I personally disable turbo boot for heat and power consumption concerns with close to no differences in terms of performances feeling.

NOW: in order to fix the max frequency of all 4 cpus to 2,6GHz, shall I write in terminal:
sudo cpufreq-set -u 2.6Ghz


IS this correct?
How can I close this topic? or is not my rule?
Lorenzo

[Laurent85]

Hi sirlitoldo

modulo acpi-cpufreq

Hmm I see you forced the deprecated driver, it's up to you

NOW: in order to fix the max frequency of all 4 cpus to 2,6GHz, shall I write in terminal:
sudo cpufreq-set -u 2.6Ghz

Here is the command to set the upper limit for all cpu's to 2.6 GHz:

Code: Select all

for cpu in $(gawk '/processor/ {print $3}' /proc/cpuinfo); do sudo cpufreq-set -c $cpu -u 2.6GHz; done

How can I close this topic?

Edit your first post and add [SOLVED] to the topic.

Ok Laurent, thks for all, may I close the topic or the administrator put it in "solved"?

The last new: update system up to 17.3 "Rosa" all return back same in 17.1: applet handable my user. Solved (again)
