You need a supported cpu, and a +kernel that supports sysfs to run this daemon. + +The name is somewhat misleading, as any processor supported by the kernel +cpufreq driver will work, not just processors supporting AMD's +PowerNow! technology. This daemon works best with processors that support +more then 2 frequency steps, like those with AMD's PowerNow!, and Intel's +Pentium M family. +.SH OPTIONS +.TP +.B \-h +Prints a help message. +.TP +.B \-d +Don't detach from terminal (default is to detach and run in the background) +.TP +.B \-v +Increase output verbosity, can be used more than once. +.TP +.B \-q +Quiet mode, only emergency output. +.TP +.B \-n +Include nice'd processes in calculations. +.TP +.B \-m +Modes of operation, 0 = SINE, 1 = AGGRESSIVE (default), 2 = PASSIVE, 3 = LEAPS +.TP +.B \-s +Frequency step in kHz (default = 100000) +.TP +.B \-p +Polling frequency in msecs (default = 1000) +.TP +.B \-u +CPU usage upper limit percentage [0 .. 100, default 80] +.TP +.B \-l +CPU usage lower limit percentage [0 .. 100, default 20] +.SH MODES +There are 4 modes supported by this client: + +Mode 0, SINE, changes the frequency as a sine wave function, raising the +frequency by "step" Hz every time the CPU usage goes over 80%, +and decreases it by "step" Hz when the CPU usage falls under 20%. + +Mode 1, AGGRESSIVE, changes frequency by a sawtooth function. +Immediately jumps to the highest frequency whenever CPU usage goes +over 80%, and decreases by "step" Hz as usage drops below +20%. This is the default behavior. + +Mode 2, PASSIVE, is the inverse of AGGRESSIVE. +Immediately jump to lowest frequency when usage drops below 20%. +Raise by "step" Hz if it goes above 80%. + +Mode 3, LEAPS, immediately jumps to the highest frequency if usage is above +80%, and immediately jumps to the lowest frequency if usage is below 20%. +.SH PHILOSOPHY +Why another CPUFreq client daemon? + +Some other daemons are better suited for two speed states, and +toggle between two states based upon load. This daemon does a better job +handling intermediate steps. + +Other daemons are written in Perl, Python, or C++. This is a simple C +program. + +Some other daemons rely on APM or ACPI. +The sysfs interface to the 2.6 +kernel is simple, completely sufficient, and completely portable to all +architectures that support the CPUfreq support in the kernel. + +Some other daemons change thier behavior based upon battery status, AC +status, temperature, etc. What good is having a nice powerful laptop if +you can't use it at full speed, even for a few seconds, while on battery +power? This daemon just measures CPU load, and bases decisions solely +upon that. + +SMP systems are supported, making this daemon useful for servers, too! +.SH AUTHOR +The powernowd program was written by John Clemens + +This manual page was written by Bdale Garbee , +for the Debian project (but may be used by others). diff --git a/system/powernowd/powernowd.SlackBuild b/system/powernowd/powernowd.SlackBuild new file mode 100644 index 0000000000..8671a5a2ad --- /dev/null +++ b/system/powernowd/powernowd.SlackBuild @@ -0,0 +1,65 @@ +#!/bin/sh + +# Slackware build script for powernowd + +# Written by Daniel LEVAI leva@ecentrum.hu + +PRGNAM=powernowd +VERSION=${VERSION:-1.00} +ARCH=${ARCH:-i486} +BUILD=${BUILD:-1} +TAG=${TAG:-_SBo} + +CWD=$(pwd) +TMP=${TMP:-/tmp/SBo} +PKG=$TMP/package-$PRGNAM +OUTPUT=${OUTPUT:-/tmp} + +if [ "$ARCH" = "i486" ]; then + SLKCFLAGS="-O2 -march=i486 -mtune=i686" +elif [ "$ARCH" = "i686" ]; then + SLKCFLAGS="-O2 -march=i686 -mtune=i686" +elif [ "$ARCH" = "x86_64" ]; then + SLKCFLAGS="-O2 -fPIC" +fi + +set -e # Exit on most errors + +rm -rf $PKG +mkdir -p $TMP $PKG $OUTPUT +cd $TMP +rm -rf $PRGNAM-$VERSION +tar xvf $CWD/$PRGNAM-$VERSION.tar.gz +cd $PRGNAM-$VERSION +chown -R root:root . +find . \ + \( -perm 777 -o -perm 775 -o -perm 711 -o -perm 555 -o -perm 511 \) \ + -exec chmod 755 {} \; -o \ + \( -perm 666 -o -perm 664 -o -perm 600 -o -perm 444 -o -perm 440 -o -perm 400 \) \ + -exec chmod 644 {} \; + +# We'll do all of this manually +gcc $SLKCFLAGS -Wall -o powernowd powernowd.c + +mkdir -p $PKG/usr/sbin +strip --strip-unneeded powernowd +install -m 755 powernowd $PKG/usr/sbin/ + +mkdir -p $PKG/etc/rc.d/ +cat $CWD/rc.powernowd.new > $PKG/etc/rc.d/rc.powernowd.new + +mkdir -p $PKG/usr/man/man1 +gzip -9c $CWD/powernowd.1 > $PKG/usr/man/man1/powernowd.1.gz + +mkdir -p $PKG/usr/doc/$PRGNAM-$VERSION +cp -a \ + README \ + $PKG/usr/doc/$PRGNAM-$VERSION +cat $CWD/$PRGNAM.SlackBuild > $PKG/usr/doc/$PRGNAM-$VERSION/$PRGNAM.SlackBuild + +mkdir -p $PKG/install +cat $CWD/slack-desc > $PKG/install/slack-desc +cat $CWD/doinst.sh > $PKG/install/doinst.sh + +cd $PKG +/sbin/makepkg -l y -c n $OUTPUT/$PRGNAM-$VERSION-$ARCH-$BUILD$TAG.tgz diff --git a/system/powernowd/powernowd.info b/system/powernowd/powernowd.info new file mode 100644 index 0000000000..8e21b7779c --- /dev/null +++ b/system/powernowd/powernowd.info @@ -0,0 +1,8 @@ +PRGNAM="powernowd" +VERSION="1.00" +HOMEPAGE="http://deater.net/john/powernowd.html" +DOWNLOAD="http://deater.net/john/powernowd-1.00.tar.gz" +MD5SUM="abc48b690d104e9e71a85400ba19d799" +MAINTAINER="Daniel LEVAI" +EMAIL="leva@ecentrum.hu" +APPROVED="rworkman" diff --git a/system/powernowd/rc.powernowd.new b/system/powernowd/rc.powernowd.new new file mode 100644 index 0000000000..fe6f50f15e --- /dev/null +++ b/system/powernowd/rc.powernowd.new @@ -0,0 +1,54 @@ +#!/bin/sh + +# Written by Daniel LEVAI for the Slackware package +# Modified by Robby Workman + +# For the options, see the README of the man page +#OPTS='-q' + +powernowd_start() { + local PID=$(pgrep -x powernowd); + if [ $PID ];then + echo "powernowd is already running ($PID)" + exit 1 + else + /usr/sbin/powernowd $OPTS + fi +} + +powernowd_stop() { + local PID=$(pgrep -x powernowd); + if [ -z $PID ];then + echo "powernowd is not running" + exit 1 + else + local i=1 + while pgrep -x powernowd > /dev/null;do + if [ $i -gt 3 ];then + echo "Couldn't stop powernowd..." + exit 1 + fi + pkill -x powernowd + i=$(( $i + 1 )); + sleep 1; + done + fi +} + +case "$1" in +start) + powernowd_start +;; +stop) + powernowd_stop +;; +restart) + powernowd_stop + sleep 1 + powernowd_start +;; +*) + echo "$0 " +;; +esac + diff --git a/system/powernowd/slack-desc b/system/powernowd/slack-desc new file mode 100644 index 0000000000..0ee78d0492 --- /dev/null +++ b/system/powernowd/slack-desc @@ -0,0 +1,19 @@ +# HOW TO EDIT THIS FILE: +# The "handy ruler" below makes it easier to edit a package description.
