seidler2547 / amd-fx-cpufreq

Last active December 16, 2015 05:49

Plagued by the wrong CPU frequency scaling on AMD FX processors (e.g. on 3.2.0 kernel), I wrote this simple userspace governor script which will always set the two Bulldozer/Piledriver cores in the same module to the same frequency based on the current CPU usage.

	for i in $(grep -Eo "cpu[0-9]+" /proc/stat); do cpufreq-set -c ${i/cpu/} -g userspace ; done

	bash -c 'while :;do grep -E "cpu[0-9]+" /proc/stat;sleep 0.2;done\|gawk '"'"'BEGIN{getline MINF<"/sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq" ;getline MAXF<"/sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq"}{cn=$1;sub(/cpu/,"",cn);if(cn==0)for(i in cu){ocu[i]=cu[i];cu[i]=0;oci[i]=ci[i];ci[i]=0}pg=rshift(cn,1);for(i=2;i<=NF;i++){if(i!=5)cu[pg]+=$i;ci[pg]+=$i}if(pg2!=cn){tf=200(cu[pg]-ocu[pg])/(ci[pg]-oci[pg]);if(tf>100)tf=100;if(tf<0)tf=0;sc=tf(MAXF-MINF)/100+MINF-300000;sc-=sc%100000;for(j=0;j<2;j++)print sc\|"cat>/sys/devices/system/cpu/cpu"(pg2+j)"/cpufreq/scaling_setspeed"}}'"'&"

Automatic brightness script for use with ACPI Ambient Light sensor and xbrightness. Other sources of ambient brightness are also possible of course.

	while :
	do
	BR=`cat /sys/class/als/acpi_als0/illuminance`
	echo -n $BR
	[ $BR -lt 8 ] && BR=0
	DB=`echo "l($BR+1)*l($BR+1)" \| bc -l`

Zionworx to Lyricue

	#!/bin/sh

	# you will need to get the Windows TurboDB Exchange s/w, like this:
	# # wget http://dataweb.de/download/turbodbtools/tdbdataX.zip
	# # unzip tdbdataX.zip
	# then, copy all files from C:\Documents and Settings\All Users\...\Zionworx\2.6\Data
	# into the current working dir
	# Then, run this script, then you can import the lyricue.xmlz into Lyricue
	# You will also need:
	# - wine (because the Linux exporter of TurboDB is broken)
