  	  CPU idle is a generic framework for supporting software-controlled
  	  idle processor power management.  It includes modular cross-platform
  	  governors that can be swapped during runtime.

  	  If you're using an ACPI-enabled platform, you should say Y here.

  	help
  	  This governor implements a simplified idle state selection method
  	  focused on timer events and does not do any interactivity boosting.
  
  	  Some workloads benefit from using it and it generally should be safe
  	  to use.  Say Y here if you are not happy with the alternatives.
