# # ARM CPU Idle drivers # config ARM_CPUIDLE bool "Generic ARM/ARM64 CPU idle Driver" select DT_IDLE_STATES select CPU_IDLE_MULTIPLE_DRIVERS 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 help Select this to enable cpuidle on Calxeda processors. config ARM_KIRKWOOD_CPUIDLE bool "CPU Idle Driver for Marvell Kirkwood SoCs" depends on MACH_KIRKWOOD && !ARM64 help This adds the CPU Idle driver for Marvell Kirkwood SoCs. config ARM_ZYNQ_CPUIDLE bool "CPU Idle Driver for Xilinx Zynq processors" depends on ARCH_ZYNQ && !ARM64 help Select this to enable cpuidle on Xilinx Zynq processors. config ARM_U8500_CPUIDLE bool "Cpu Idle Driver for the ST-E u8500 processors" depends on ARCH_U8500 && !ARM64 help Select this to enable cpuidle for ST-E u8500 processors config ARM_AT91_CPUIDLE bool "Cpu Idle Driver for the AT91 processors" default y depends on ARCH_AT91 && !ARM64 help Select this to enable cpuidle for AT91 processors config ARM_EXYNOS_CPUIDLE bool "Cpu Idle Driver for the Exynos processors" depends on ARCH_EXYNOS && !ARM64 select ARCH_NEEDS_CPU_IDLE_COUPLED if SMP help Select this to enable cpuidle for Exynos processors config ARM_MVEBU_V7_CPUIDLE bool "CPU Idle Driver for mvebu v7 family processors" depends on ARCH_MVEBU && !ARM64 help Select this to enable cpuidle on Armada 370, 38x and XP processors.
