38 prompt "Default CPUFreq governor"
44 This option sets which CPUFreq governor shall be loaded at
51 Use the CPUFreq governor 'performance' as default. This sets
59 Use the CPUFreq governor 'powersave' as default. This sets
67 Use the CPUFreq governor 'userspace' as default. This allows
78 Use the CPUFreq governor 'ondemand' as default. This allows
80 loading your cpufreq low-level hardware driver.
81 Be aware that not all cpufreq drivers support the ondemand
91 Use the CPUFreq governor 'conservative' as default. This allows
93 loading your cpufreq low-level hardware driver.

146 tristate "'ondemand' cpufreq policy governor"
149 'ondemand' - This driver adds a dynamic cpufreq policy governor.

165 tristate "'conservative' cpufreq governor"
169 'conservative' - this driver is rather similar to the 'ondemand'

190 bool "'schedutil' cpufreq policy governor"
198 utilization is frequency-invariant, the new frequency is also
209 tristate "Generic DT based cpufreq driver"
214 This adds a generic DT based cpufreq driver for frequency management.
221 tristate "Virtual cpufreq driver"
224 This adds a virtualized cpufreq driver for guest kernels that
225 read/writes to a MMIO region for a virtualized cpufreq device to
230 to enable accurate Per-Entity Load Tracking for tasks running in the guest.
235 bool "Generic DT based cpufreq platdev driver"
238 This adds a generic DT based cpufreq platdev driver for frequency
239 management. This creates a 'cpufreq-dt' platform device, on the
