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 <clemej@alum.rpi.edu> - -This manual page was written by Bdale Garbee <bdale@gag.com>, -for the Debian project (but may be used by others). |
