Package cpufrequtils, which seems to be superseded by cpupower, but I did not see this one packaged yet. I am not sure whether cpufrequtils is part of a default install, but even if not I do believe that ondemand is standard governor in Linux. martin@merkaba:~> grep CPU_FREQ /boot/config-3.2.0-3-amd64 CONFIG_CPU_FREQ=y CONFIG_CPU_FREQ_TABLE=y CONFIG_CPU_FREQ_STAT=m # CONFIG_CPU_FREQ_STAT_DETAILS is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE is not set # CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND=y # CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set CONFIG_CPU_FREQ_GOV_PERFORMANCE=y CONFIG_CPU_FREQ_GOV_POWERSAVE=m CONFIG_CPU_FREQ_GOV_USERSPACE=m CONFIG_CPU_FREQ_GOV_ONDEMAND=y CONFIG_CPU_FREQ_GOV_CONSERVATIVE=m And then even if cpufrequtils is not installed the kernel should do CPU frequency scaling provided that udev finds and loads a kernel driver: martin@merkaba:~> grep CPUFREQ /boot/config-3.2.0-3-amd64 CONFIG_X86_PCC_CPUFREQ=m CONFIG_X86_ACPI_CPUFREQ=m It easy to verify this with a default install.
