9 CPU idle is a generic framework for supporting software-controlled
10 idle processor power management. It includes modular cross-platform
11 governors that can be swapped during runtime.
13 If you're using an ACPI-enabled platform, you should say Y here.
17 config CPU_IDLE_MULTIPLE_DRIVERS
18 bool "Support multiple cpuidle drivers"
21 Allows the cpuidle framework to use different drivers for each CPU.
22 This is useful if you have a system with different CPU latencies and
23 states. If unsure say N.
