CONFIG_CPU_FREQ_24_API: /proc/sys/cpu/ interface (2.4. / OLD)

General informations

The Linux kernel configuration item CONFIG_CPU_FREQ_24_API has multiple definitions:

/proc/sys/cpu/ interface (2.4. / OLD) found in drivers/cpufreq/Kconfig

The configuration item CONFIG_CPU_FREQ_24_API:

• prompt: /proc/sys/cpu/ interface (2.4. / OLD)
• type: bool
• depends on: ( CONFIG_CPU_FREQ_GOV_USERSPACE ) && ( CONFIG_SYSCTL )
• defined in drivers/cpufreq/Kconfig
• found in Linux kernels: 2.5.64–2.5.75, 2.6.0–2.6.10

Help text

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.

For details, take a look at Documentation/cpu-freq/.

If in doubt, say N.

/proc/sys/cpu/ interface (2.4. / OLD) found in arch/ppc/Kconfig

The configuration item CONFIG_CPU_FREQ_24_API:

• prompt: /proc/sys/cpu/ interface (2.4. / OLD)
• type: bool
• depends on: CONFIG_CPU_FREQ
• defined in arch/ppc/Kconfig
• found in Linux kernels: 2.5.67–2.5.75

Help text

This enables the /proc/sys/cpu/ sysctl interface for controlling CPUFreq, as known from the 2.4.-kernel patches for CPUFreq. 2.5 uses a sysfs interface instead. Please note that some drivers do not work well with the 2.4. /proc/sys/cpu sysctl interface, so if in doubt, say N here.

For details, take a look at linux/Documentation/cpufreq.

/proc/sys/cpu/ interface (2.4.) found in arch/i386/Kconfig

The configuration item CONFIG_CPU_FREQ_24_API:

• prompt: /proc/sys/cpu/ interface (2.4.)
• type: bool
• depends on: CONFIG_CPU_FREQ
• defined in arch/i386/Kconfig
• found in Linux kernels: 2.5.45

Help text

This enables the /proc/sys/cpu/ sysctl interface for controlling CPUFreq, as known from the 2.4.-kernel patches for CPUFreq. Note that some drivers do not support this interface or offer less functionality.

If you say N here, you'll be able to control CPUFreq using the new /proc/cpufreq interface.

For details, take a look at linux/Documentation/cpufreq.

If in doubt, say N.
