[SOLVED] cpufreq & systemd

Roken · 2012-08-15 23:16:52

Just noticed a problem with cpufreq using systemd.

Before systemd I had a script that would let me change the cpufreq across all 4 cores, restarting cpufreq with /etc/rc.d/cpufreq restart.

I've got the cpufreq.service installed and running, pointing to the same /etc/conf.d/cpufreq and am restarting with systemctl restart cpufreq.service. However, now it only affects the first core. cpufreq is started from the service with the -r parameter.

Any idea how I can force it to change all 4 cores?

for info, the script is:

#!/bin/bash

confile="/etc/conf.d/cpufreq"
freq=$(zenity --list --radiolist \
--title="Select a frequency" \
--column="Select one" --column "Frquency" \
FALSE	"2.20GHz" \
FALSE	"2.70GHz" \
FALSE	"3.40GHz")

if [ -z $freq ]; then
	zenity --warning --text "Nothing changed"
	exit 1
fi

freq=`echo $freq | sed 's/GHz.*//'`
#echo $freq

sed -i -e 's/\(max\_freq\=.\).*\(.Hz.\)/\1'$freq'\2/g' $confile
systemctl restart cpufreq.service

#cat $confile
zenity --warning --text "CPU Max Frequency changed to $freq"

and cpufreq.service:

[Unit]
Description=CPU frequency scaling daemon

[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/conf.d/cpufreq
ExecStart=/usr/bin/cpufreq-set -r -g $governor -d $min_freq -u $max_freq

Cpufreq is about to be dropped. Use cpupower. See the publicdev mailing list for this discussion.

OK, took more work than intended (I have a comky reporting the current ferquency and had to rewrite the sed lines to extract the correct info). cpupower seems to be working as expected so, even though not a solution to cpufreq, it solved my need and marking as solved, thank you.
