CPU_frequency_scaling

Post#1 by kultex » 07 May 2019, 20:30

How can I change the governor.

I see, that the cpu scales with " watch grep \"cpu MHz\" /proc/cpuinfo".

But there is no "cpupower" command, no "cpufreq-set" command

Maybe somebody can help me.....

strange, that "cpufreq-set" is not available, as mentioned in the slackware docs

so only with echo - but there is nothing to try out, because only performance and powersave are available

Code: Select all

root@porteus:/home/guest# cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
performance powersave
normally with powersave on idle destop the frequency should stay quite down, but it jumps all the time and also quite high - so I have to compare this with other distributions, if this is normal on the celeron N3050 - because the consumption of power is quite high compared to windows....

cpufreq-set is part of the cpufrequtils package, if you want to try it, but as you say, there's not much to try..

Hmm.. is your N3050 box using the Intel i915 driver?

If so, you may get a sliver of power saving from using this cheatcode for the display framebuffer compression:

i915.enable_fbc=1

This was thanks to the Archlinux docs about it:

https://wiki.archlinux.org/index.php/Intel_graphics

Also, perhaps running Powertop might be beneficial to spot power hogs. I've even used it in the past to quickly disable stuff (careful) to see what the effects were.

More Powertop info can be found here, along with a very useful translation option:

https://software.intel.com/en-us/articl ... -primer-1/

Other slivers of power might be saved by turning the backlight down (xbacklight etc), and running a lighter colored desktop theme for easier readability.
That's a UNIX book - cool. -Garth

I think, that this are all the errors - for example, if you open mousepad form the terminal as root, the CPU goes crazy

eg: when you open the xfce4 power manager in debug mode, it prints errors, the networkmanager prints errors, when you shut down XFCE, you can see errors....

First I have to organize a new usb-stick to try other distros, to check, whats normal with this CPU and then see, whats possible......

I found a free stick, where I installed Lubuntu with kernel 4.17 and the cpu frequency in Porteus is NOT normal
  • in Lubuntu in powersave mode both CPUs never go higher than 1000MHZ - whatever normal work you do
  • in Porteus in powersave mode 1.CPU is quite normal - second CPU is absolut to high - it never goes under 1500MHZ even on idle desktop
I even can feel it on the bottom of the laptop - in Lubuntu, it does not get warm - in Porteus its quite warm....

and of course I used all powertop possibilities and the i915 cheatcode....

I try to do some measurements next days....

One more thing - powertop is not working correctly, because cpufreq_stats is not configured in the kernel

Code: Select all

root@porteus:/home/guest# powertop
modprobe cpufreq_stats failedLoaded 0 prior measurements

rethinking the whole problem last night - that the bottom of the laptop with porteus feels wormer can also be conected to my sandisk ultra fit USB-stick - it gets really hot, just when it is plugged in..... - smallness has its value.

So first test is finished - of course with Porteus started at 9:25 and let the system run with black screen until 10% of the battery level

Code: Select all

<channel name="xfce4-power-manager" version="1.0">
  <property name="xfce4-power-manager" type="empty">
    <property name="presentation-mode" type="bool" value="false"/>
    <property name="dpms-sleep-mode" type="string" value="Standby"/>
    <property name="lock-screen-suspend-hibernate" type="bool" value="false"/>
    <property name="power-button-action" type="uint" value="0"/>
    <property name="critical-power-action" type="uint" value="1"/>
    <property name="brightness-switch-restore-on-exit" type="int" value="1"/>
    <property name="brightness-switch" type="int" value="0"/>
    <property name="blank-on-ac" type="int" value="10"/>
    <property name="dpms-on-ac-sleep" type="uint" value="0"/>

and it stooped at 19:49:36

Just watch out for the catch-22 of obsessing about cpufreq and power savings ...

If you are doing real work with it, say compiling a kernel, and it takes longer to do so, the overall power consumed may be the same as if you had cpufreq cranked up and the compile finishes much faster.

Which version of RC1 are you using? I've found that the XFCE version seems to react simlarly to 4.0 when I put the cpufreq xfce4 applet up near the clock ....

And this is on Atom cpu's too. Seems ok, but I haven't gone into greater depth than you have..
That's a UNIX book - cool. -Garth

sorry for my late answer, but I did not check, you answered here.

I think, it is not an obsession to check, if cpufreq is working properly. Its the first thing, I do. And of course, it makes no difference, when you are compiling a kernel. But it makes a difference, when you just answer emails or write texts, as I do most of the time, I use my laptop.
Compiling a kernel or rendering Videos, does another machine.

My hard job will finish in a week, so I will continue then.....

CPU_frequency_scaling

Post#13 by kultex » 10 Sep 2019, 17:40

it was not possible, to find another distro without systemd, where xfce4-power-manager was working ok, so I had to look for something else...

based on a script - https://github.com/jerrinfrncs/batterynotif - I did some modifications, that did what I was looking for

Code: Select all

#!/bin/bash
PATH=/usr/local/bin:/usr/bin:/bin
POWERSUPPLY="/sys/class/power_supply/ADP1/online" # could be different on your system!
NOT_CHARGING="0"
logfile="/home/guest/power.log"
 
while true
do
	STATUS=$(cat $POWERSUPPLY) #charger connected or not
    	battery_level=`upower -i $(upower -e | grep BAT) | grep --color=never -E percentage|xargs|cut -d' ' -f2|sed s/%//`

    	if [ $battery_level -ge 80 -a $STATUS = 1 ] #battery Charged
    	then 
	echo "Script and test started $(date +"%T") - Battery level is ${battery_level}%" >>$logfile 

	elif [ $battery_level -le 5 -a $STATUS = $NOT_CHARGING ] #battery low suspend
    	then
	echo "Sleep $(date +"%T") - Battery level is $battery_level%" >>$logfile  
	sleep 2s
	dbus-send --system --print-reply --dest="org.freedesktop.UPower" /org/freedesktop/UPower org.freedesktop.UPower.Suspend
	#killall sakura
    	fi
   sleep 300
done
...

so I could also compare the Porteus openbox version with the LXDE version (the openbox-version is much better with scaling).

Here the result:

Openbox: 10h45m
Script and test started 20:45:46 - Battery level is 100%
Sleep 07:30:58 - Battery level is 5%

LXDE: 9h35m
Script and test started 23:25:29 - Battery level is 100%
Sleep 09:00:45 - Battery level is 5%

Slax - I dont like Slax very much, but Slax is absolutly top in scaling - it stays mainly on 500 Mhz - the script did not work - so I had to change:

Code: Select all

#!/bin/bash
PATH=/usr/local/bin:/usr/bin:/bin
POWERSUPPLY="/sys/class/power_supply/ADP1/online" # could be different on your system!
NOT_CHARGING="0"
logfile="/home/guest/power.log"
 
while true
do
	STATUS=$(cat $POWERSUPPLY) #charger connected or not
    	battery_level=$(cat /sys/class/power_supply/BAT0/capacity)

    	if [ $battery_level -ge 80 -a $STATUS = 1 ] #battery Charged
    	then 
	echo "Script and test started $(date +"%T") - Battery level is ${battery_level}%" >>$logfile 

	elif [ $battery_level -le 5 -a $STATUS = $NOT_CHARGING ] #battery low suspend
    	then
	echo "Sleep $(date +"%T") - Battery level is $battery_level%" >>$logfile  
	sleep 2s
	pm-suspend
    	fi
   sleep 300
done
Slax: 11h10min
Script and test started 21:17:42 - Battery level is 100%
Sleep 08:27:45 - Battery level is 5%

An interesting script. But it doesn't work for me.

Code: Select all

cat: /sys/class/power_supply/ADP1/online: No such file or directory
/home/guest/Battery.sh: line 12: [: too many arguments
/home/guest/Battery.sh: line 16: [: too many arguments
It's true I don't have the /ADP1/online file, most likely because I'm not plugged in, but I do have the /sys/class/power_supply/BAT0/capacity file.

Code: Select all

guest@porteus:~$ ls /sys/class/power_supply/BAT0/
alarm               current_now   present        uevent
capacity            cycle_count   serial_number  voltage_min_design
capacity_level      device@       status         voltage_now
charge_full         manufacturer  subsystem@
charge_full_design  model_name    technology
charge_now          power/        type
guest@porteus:~$ 
-update-

Plugged in I have POWERSUPPLY="/sys/class/power_supply/AC/online" and power.log shows:

Code: Select all

Script and test started 23:46:44 - Battery level is 137%
Script and test started 23:51:44 - Battery level is 137%

Post#15 by donald » 11 Sep 2019, 03:13

Hi Kultex

Different system - amd (k8 i think), Porteus 4 xfce 64

scaling seems to work:

Code: Select all

guest@porteus:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_frequencies
2600000 2400000 2200000 2000000 1800000 1000000 
guest@porteus:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
ondemand performance schedutil 
guest@porteus:~$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
ondemand
guest@porteus:~$ cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq
1000000
1000000
But if i use the watch command - like you do -

Code: Select all

guest@porteus:~$ watch -n 1 "sensors && grep \"cpu MHz\" /proc/cpuinfo"
the MHz are constantly jumping up and down.

What if you use cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_cur_freq while idle?
