For details, take a look at <file:Documentation/cpu-freq/>. If you don't have such processor, say N config CPU_FREQ_CBE_PMI bool "CBE frequency scaling using PMI interface" depends on CPU_FREQ_CBE default n help Select this, if you want to use the PMI interface to switch frequencies. Using PMI, the processor will not only be able to run at lower speed, but also at lower core voltage. config CPU_FREQ_MAPLE bool "Support for Maple 970FX Evaluation Board" depends on PPC_MAPLE help This adds support for frequency switching on Maple 970FX Evaluation Board and compatible boards (IBM JS2x blades). config CPU_FREQ_PMAC bool "Support for Apple PowerBooks" depends on ADB_PMU && PPC32 help This adds support for frequency switching on Apple PowerBooks, this currently includes some models of iBook & Titanium PowerBook. config CPU_FREQ_PMAC64 bool "Support for some Apple G5s" depends on PPC_PMAC && PPC64 help This adds support for frequency switching on Apple iMac G5, and some of the more recent desktop G5 machines as well. config PPC_PASEMI_CPUFREQ bool "Support for PA Semi PWRficient" depends on PPC_PASEMI default y help This adds the support for frequency switching on PA Semi PWRficient processors. config POWERNV_CPUFREQ tristate "CPU frequency scaling for IBM POWERNV platform" depends on PPC_POWERNV default y help This adds support for CPU frequency switching on IBM POWERNV platform ��Kconfig��0000644��00000023454�14722072270�0006062 0��ustar�00��# SPDX-License-Identifier: GPL-2.0-only menu "CPU Frequency scaling" config CPU_FREQ bool "CPU Frequency scaling" select SRCU help CPU Frequency scaling allows you to change the clock speed of CPUs on the fly. This is a nice method to save power, because the lower the CPU clock speed, the less power the CPU consumes. Note that this driver doesn't automatically change the CPU clock speed, you need to either enable a dynamic cpufreq governor (see below) after boot, or use a userspace tool. For details, take a look at <file:Documentation/cpu-freq>. If in doubt, say N. if CPU_FREQ config CPU_FREQ_GOV_ATTR_SET bool config CPU_FREQ_GOV_COMMON select CPU_FREQ_GOV_ATTR_SET select IRQ_WORK bool config CPU_FREQ_STAT bool "CPU frequency transition statistics" help Export CPU frequency statistics information through sysfs.

This sets the frequency statically to the highest frequency supported by the CPU. config CPU_FREQ_DEFAULT_GOV_POWERSAVE bool "powersave" select CPU_FREQ_GOV_POWERSAVE help Use the CPUFreq governor 'powersave' as default. This sets the frequency statically to the lowest 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 a userspace program shall be able to set the CPU dynamically without having to enable the userspace governor manually. config CPU_FREQ_DEFAULT_GOV_ONDEMAND bool "ondemand" select CPU_FREQ_GOV_ONDEMAND select CPU_FREQ_GOV_PERFORMANCE help Use the CPUFreq governor 'ondemand' as default. This allows you to get a full dynamic frequency capable system by simply loading your cpufreq low-level hardware driver. Be aware that not all cpufreq drivers support the ondemand governor. If unsure have a look at the help section of the driver. Fallback governor will be the performance governor. config CPU_FREQ_DEFAULT_GOV_CONSERVATIVE bool "conservative" select CPU_FREQ_GOV_CONSERVATIVE select CPU_FREQ_GOV_PERFORMANCE help Use the CPUFreq governor 'conservative' as default. This allows you to get a full dynamic frequency capable system by simply loading your cpufreq low-level hardware driver. Be aware that not all cpufreq drivers support the conservative governor. If unsure have a look at the help section of the driver. Fallback governor will be the performance governor. config CPU_FREQ_DEFAULT_GOV_SCHEDUTIL bool "schedutil" depends on SMP select CPU_FREQ_GOV_SCHEDUTIL select CPU_FREQ_GOV_PERFORMANCE help Use the 'schedutil' CPUFreq governor by default. If unsure, have a look at the help section of that governor. The fallback governor will be 'performance'. endchoice config CPU_FREQ_GOV_PERFORMANCE tristate "'performance' governor" help This cpufreq governor sets the frequency statically to the highest available CPU frequency. To compile this driver as a module, choose M here: the module will be called cpufreq_performance. If in doubt, say Y. config CPU_FREQ_GOV_POWERSAVE tristate "'powersave' governor" help This cpufreq governor sets the frequency statically to the lowest available CPU frequency. To compile this driver as a module, choose M here: the module will be called cpufreq_powersave. If in doubt, say Y. config CPU_FREQ_GOV_USERSPACE tristate "'userspace' governor for userspace frequency scaling" help Enable this cpufreq governor when you either want to set the CPU frequency manually or when a userspace program shall be able to set the CPU dynamically, like on LART <http://www.lartmaker.nl/>. To compile this driver as a module, choose M here: the module will be called cpufreq_userspace. For details, take a look at <file:Documentation/cpu-freq/>. If in doubt, say Y. config CPU_FREQ_GOV_ONDEMAND tristate "'ondemand' cpufreq policy governor" select CPU_FREQ_GOV_COMMON help 'ondemand' - This driver adds a dynamic cpufreq policy governor. The governor does a periodic polling and changes frequency based on the CPU utilization. The support for this governor depends on CPU capability to do fast frequency switching (i.e, very low latency frequency transitions). To compile this driver as a module, choose M here: the module will be called cpufreq_ondemand. For details, take a look at linux/Documentation/cpu-freq. If in doubt, say N. config CPU_FREQ_GOV_CONSERVATIVE tristate "'conservative' cpufreq governor" depends on CPU_FREQ select CPU_FREQ_GOV_COMMON help 'conservative' - this driver is rather similar to the 'ondemand' governor both in its source code and its purpose, the difference is its optimisation for better suitability in a battery powered environment. The frequency is gracefully increased and decreased rather than jumping to 100% when speed is required. If you have a desktop machine then you should really be considering the 'ondemand' governor instead, however if you are using a laptop, PDA or even an AMD64 based computer (due to the unacceptable step-by-step latency issues between the minimum and maximum frequency transitions in the CPU) you will probably want to use this governor. To compile this driver as a module, choose M here: the module will be called cpufreq_conservative. For details, take a look at linux/Documentation/cpu-freq. If in doubt, say N. config CPU_FREQ_GOV_SCHEDUTIL bool "'schedutil' cpufreq policy governor" depends on CPU_FREQ && SMP select CPU_FREQ_GOV_ATTR_SET select IRQ_WORK help This governor makes decisions based on the utilization data provided by the scheduler. It sets the CPU frequency to be proportional to the utilization/capacity ratio coming from the scheduler. If the utilization is frequency-invariant, the new frequency is also proportional to the maximum available frequency. If that is not the case, it is proportional to the current frequency of the CPU. The frequency tipping point is at utilization/capacity equal to 80% in both cases. If in doubt, say N. comment "CPU frequency scaling drivers" config CPUFREQ_DT tristate "Generic DT based cpufreq driver" depends on HAVE_CLK && OF select CPUFREQ_DT_PLATDEV select PM_OPP help This adds a generic DT based cpufreq driver for frequency management.

For details, take a look at <file:Documentation/cpu-freq>. If in doubt, say N. endif if SUPERH config SH_CPU_FREQ tristate "SuperH CPU Frequency driver" help This adds the cpufreq driver for SuperH. Any CPU that supports clock rate rounding through the clock framework can use this driver. While it will make the kernel slightly larger, this is harmless for CPUs that don't support rate rounding. The driver will also generate a notice in the boot log before disabling itself if the CPU in question is not capable of rate rounding. For details, take a look at <file:Documentation/cpu-freq>.
