It works as a client of the CPUFreq driver. -It is designed for use with CPU's supporting AMD's PowerNow power -management scheme, as it's algorithm works better if there are more -than two CPU speeds available. (aka, ARM, AMD K6/K7, Via C3, and -Crusoe as opposed to traditional Intel and Ultrasparc). +It is designed for use with CPU's supporting AMD's PowerNow power management +scheme, as it's algorithm works better if there are more then two CPU +speeds available. (aka, ARM, AMD K6/K7, Via C3, and Crusoe as opposed to +traditional Intel and Ultrasparc). -Powernowd uses the userspace governor, which is included in the Slackware -kernel images. +This program is essentially a simple client to the CPUFreq sysfs interface. +This means that you -need- to be running Linux v2.5 or later that includes +the sysfs interface. This daemon will -not- work with the CPUFreq driver +interface included in Linux v2.4. Feel free to write your own daemon +to support that if you like; you can even use this as a starting point. +If there's enough clamoring for it, then maybe I'll whip up something. +You also need a CPU that supports frequency scaling and supports the CPUFreq +interface. This code has been tested on various AMD and PPC processors -It is not wise to run two concurrent cpu frequency adjusting programs, -for example, cpufreqd and powernowd simultaneously. +I have been running this daemon on my AMD laptop for over 2 years with no +problems to report, and it's nice that my laptop remains cool unless I'm +really doing something intensive, like watching DivX movies, without me +having to manually intervene and set the speed. I just recently bought an +Apple iBook G3, and powernowd-0.80 worked flawlessly on it right out of +the box. + + +Features: + +This daemon's goal is simplicity and speed. It doesn't try and make +too many decisions for you. That's its beauty, but it may not be what +everyone's looking for. Some of the features this daemon has: + +One, simple heuristic to determine CPU load: "user + sys" time. +Ignore "niced" programs (setiathome, itself, etc). In my mind this is +consistent with what is meant when someone 'nice's a program to begin +with. (configurable in v0.85+) Designed for CPU's that support more +then two speed states, but works well with anything. Very fast, low +overhead /proc/stat gathering (method stolen from procps). Supports SMP +Will automatically switch to 'userspace' governor. Care taken to make +the code non-root exploitable (but please audit for yourself first!) +Frequency step size is configurable (default to 100MHz/step) 4 different +behavioral modes to choose from (SINE, AGGRESSIVE, PASSIVE, LEAPS), +which determine the behavior when the load changes. Configurable from the +command line. Written in C for speed and simplicity. Logging to stdout +or syslog Configurable Polling frequency in milliseconds (defaults to 1s) +Configurable highwater/lowwater marks for CPU usage. (defaults 80/20%) + +Many similar daemons use other methods to determine what speed to use, +such as battery status, AC status, temperature, fan status, etc. They all +have their place. I however feel that in the grand scheme of things none +of the above matters. When I'm not using my CPU, I don't care if it's +running at a slower speed. When I -am- using my CPU, I only need it to +be fast enough to handle the task at hand without hiccuping. And when I'm +taxing my CPU, I want it running full speed. That's all this daemon does, +monitor CPU load and adjust the speed accordingly. Since in all reality +my CPU is idle 99% of the time (or playing mp3's which it can easily do +at it's lowest speed rating), this by definition leads to low power usage, +low temperatures, low speed fans, and better battery life. diff --git a/system/powernowd/doinst.sh b/system/powernowd/doinst.sh deleted file mode 100644 index 4fdea56905..0000000000 --- a/system/powernowd/doinst.sh +++ /dev/null @@ -1,22 +0,0 @@ -config() { - NEW="$1" - OLD="$(dirname $NEW)/$(basename $NEW .new)" - # If there's no config file by that name, mv it over: - if [ ! -r $OLD ]; then - mv $NEW $OLD - elif [ "$(cat $OLD | md5sum)" = "$(cat $NEW | md5sum)" ]; then - # toss the redundant copy - rm $NEW - fi - # Otherwise, we leave the .new copy for the admin to consider... -} - -# Keep same perms on rc.powernowd.new: -if [ -e etc/rc.d/rc.powernowd ]; then - cp -a etc/rc.d/rc.powernowd etc/rc.d/rc.powernowd.new.incoming - cat etc/rc.d/rc.powernowd.new > etc/rc.d/rc.powernowd.new.incoming - mv etc/rc.d/rc.powernowd.new.incoming etc/rc.d/rc.powernowd.new -fi - -config etc/rc.d/rc.powernowd.new - diff --git a/system/powernowd/powernowd.1 b/system/powernowd/powernowd.1 deleted file mode 100644 index 232c990f8d..0000000000 --- a/system/powernowd/powernowd.1 +++ /dev/null @@ -1,108 +0,0 @@ -.\" Hey, EMACS: -*- nroff -*- -.\" First parameter, NAME, should be all caps -.\" Second parameter, SECTION, should be 1-8, maybe w/ subsection -.\" other parameters are allowed: see man(7), man(1) -.TH POWERNOWD 1 "November 3, 2003" -.\" Please adjust this date whenever revising the manpage. -.\" -.\" Some roff macros, for reference: -.\" .nh disable hyphenation -.\" .hy enable hyphenation -.\" .ad l left justify -.\" .ad b justify to both left and right margins -.\" .nf disable filling -.\" .fi enable filling -.\" .br insert line break -.\" .sp <n> insert n+1 empty lines -.\" for manpage-specific macros, see man(7) -.SH NAME -powernowd \- control the speed and voltage of cpus -.SH SYNOPSIS -.B powernowd -.RI [ options ] -.SH DESCRIPTION -This is a simple client to the cpufreq driver, and uses the sysfs interface -in Linux kernel version 2.6.

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?
