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).

This option sets which CPUFreq governor shall be loaded at
startup. If in doubt, select 'performance'.
config CPU_FREQ_DEFAULT_GOV_PERFORMANCE
bool "performance"
select CPU_FREQ_GOV_PERFORMANCE
help
Use the CPUFreq governor 'performance' as default. This sets
the frequency statically to the highest frequency supported by
the CPU.
config CPU_FREQ_DEFAULT_GOV_USERSPACE
bool "userspace"
select CPU_FREQ_GOV_USERSPACE
help
Use the CPUFreq governor 'userspace' as default. This allows
you to set the CPU frequency manually or when an userspace
programm shall be able to set the CPU dynamically without having
to enable the userspace governor manually.

Enable this cpufreq governor when you either want to set the

be able to set the CPU dynamically, like on LART

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 2.4.-kernel patches for CPUFreq, and offers
the same functionality as long as "userspace" is the
selected governor for the specified CPU.
