CPU_FREQ (CPU_FREQ_GOV_USERSPACE), (CPU_FREQ_GOV_PERFORMANCE) (CPU_FREQ_GOV_POWERSAVE), (CPU_FREQ_TABLE) (X86_POWERNOW_K8) Ricardo Galli's 'cpudyn' package does a great job. You really should install it. It reduces CPU frequency whenever CPU power is not realli needed. At least with a 2.6.[9-11] kernel, you won't need the cpufreq patch. Just activate kernel options 'CPU Frequency scaling' (CPU_FREQ), 'userspace governor for userspace frequency scaling' (CPU_FREQ_GOV_USERSPACE), 'Performance Governor' (CPU_FREQ_GOV_PERFORMANCE) and set this to be the default governor, 'Powersave governor' (CPU_FREQ_GOV_POWERSAVE), enable the 'CPU frequency table helpers' (CPU_FREQ_TABLE) and activate 'AMD Opteron/Athlon64 PowerNow!' (X86_POWERNOW_K8) as you are told in kernel documentation file 'Documentation/cpu-freq/user-guide.txt'. At the end, there will be a daemon which reduces CPU time whenever appropriate and you'll be able to read current CPU frequency with 'cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq'. Anyone who has a gkrellm applet for this? If you have ACPI switched on, you can manually change the processor mode using the command 'echo number > /proc/acpi/processor/CPU0/profile' where number is the mode of the following table:
