- config ARM_CPUIDLE
- bool "Generic ARM/ARM64 CPU idle Driver"
- select DT_IDLE_STATES
- help
- Select this to enable generic cpuidle driver for ARM.
- It provides a generic idle driver whose idle states are configured
- at run-time through DT nodes. The CPUidle suspend backend is
- initialized by calling the CPU operations init idle hook
- provided by architecture code.
- config ARM_BIG_LITTLE_CPUIDLE
- bool "Support for ARM big.LITTLE processors"
- depends on ARCH_VEXPRESS_TC2_PM || ARCH_EXYNOS
- depends on MCPM && !ARM64
- select ARM_CPU_SUSPEND
- select CPU_IDLE_MULTIPLE_DRIVERS
- select DT_IDLE_STATES
- help
- Select this option to enable CPU idle driver for big.LITTLE based
- ARM systems. Driver manages CPUs coordination through MCPM and
- define different C-states for little and big cores through the
- multiple CPU idle drivers infrastructure.
- config ARM_CLPS711X_CPUIDLE
- bool "CPU Idle Driver for CLPS711X processors"
- depends on ARCH_CLPS711X && !ARM64 || COMPILE_TEST
- help
- Select this to enable cpuidle on Cirrus Logic CLPS711X SOCs.
- config ARM_HIGHBANK_CPUIDLE
- bool "CPU Idle Driver for Calxeda processors"
- depends on ARM_PSCI && !ARM64
- select ARM_CPU_SUSPEND
