3 bool "CPU idle PM support"
4 default y if ACPI || PPC_PSERIES

8 CPU idle is a generic framework for supporting software-controlled
9 idle processor power management. It includes modular cross-platform
10 governors that can be swapped during runtime.
12 If you're using an ACPI-enabled platform, you should say Y here.
16 config CPU_IDLE_MULTIPLE_DRIVERS
17 bool "Support multiple cpuidle drivers"
20 Allows the cpuidle framework to use different drivers for each CPU.
21 This is useful if you have a system with different CPU latencies and
22 states. If unsure say N.
24 config CPU_IDLE_GOV_LADDER
25 bool "Ladder governor (for periodic timer tick)"
28 config CPU_IDLE_GOV_MENU
29 bool "Menu governor (for tickless system)"
32 config ARCH_NEEDS_CPU_IDLE_COUPLED
35 config CPU_IDLE_CALXEDA
36 bool "CPU Idle Driver for Calxeda processors"
37 depends on ARCH_HIGHBANK
39 Select this to enable cpuidle on Calxeda processors.
42 bool "CPU Idle Driver for Xilinx Zynq processors"
45 Select this to enable cpuidle on Xilinx Zynq processors.
