CPU idle is a generic framework for supporting software-controlled
|
|
idle processor power management. It includes modular cross-platform
|
|
governors that can be swapped during runtime.
|
|
|
|
If you're using an ACPI-enabled platform, you should say Y here.

MTK governor is used for MTK SoCs to select the correct idle state,
|
|
which applies system scenario-based policy.

MTK governor is specified for MTK SoCs.

MTK CPUidle drivers should be paired with MTK governer.

MTK menu governor is based on upstream menu governor,

and modify predict_us policy to fit

execution characteristics of MTK SoCs.

|
MTK added many proprietary cpuidle drivers and governors.
|
|
And some of them set to be default for all projects.
|
|
But not all (MTK) projects use these driver.
|
|
Set this option to avoid using MTK driver / gorvernor by default.
