Overview:
|
||||
This is a very simple program that will adjust the speed of your CPU
|
||||
depending on system load. 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).

|
||||
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.

.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. 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.
|
||||

|

|

.B \-l
|

|
||||
.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!
