CONFIG_ARM_BIG_LITTLE_CPUIDLE: Support for ARM big.LITTLE processors

General informations

The Linux kernel configuration item CONFIG_ARM_BIG_LITTLE_CPUIDLE:

• prompt: Support for ARM big.LITTLE processors
• type: bool
• depends on: ( CONFIG_ARCH_VEXPRESS_TC2_PM || CONFIG_ARCH_EXYNOS || CONFIG_COMPILE_TEST ) && ( CONFIG_MCPM && ! CONFIG_ARM64 )
• defined in drivers/cpuidle/Kconfig.arm
• found in Linux kernels: 3.13–3.19, 4.0–4.20, 5.0–5.19, 6.0–6.12

Help text

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.
