config CPU_FREQ_PROC_INTF tristate "/proc/cpufreq interface (deprecated)" depends on CPU_FREQ && PROC_FS help This enables the /proc/cpufreq interface for controlling CPUFreq. Please note that it is recommended to use the sysfs interface instead (which is built automatically). For details, take a look at linux/Documentation/cpufreq. If in doubt, say N. config CPU_FREQ_GOV_USERSPACE tristate "'userspace' governor for userspace frequency scaling" depends on CPU_FREQ help Enable this cpufreq governor when you either want to set the CPU frequency manually or when an userspace programm shall be able to set the CPU dynamically, like on LART ( http://www.lart.tudelft.nl/ ) For details, take a look at linux/Documentation/cpufreq. If in doubt, say Y. config CPU_FREQ_24_API bool "/proc/sys/cpu/ interface (2.4. / OLD)" depends on CPU_FREQ && SYSCTL && CPU_FREQ_GOV_USERSPACE help This enables the /proc/sys/cpu/ sysctl interface for controlling the CPUFreq,"userspace" governor. This is the same interface as known from the.4.-kernel patches for CPUFreq, and offers the same functionality as long as "userspace" is the selected governor for the specified CPU. For details, take a look at linux/Documentation/cpufreq. If in doubt, say N.
