   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.
  12
  13           If you're using an ACPI-enabled platform, you should say Y here.

  29           This governor implements a simplified idle state selection method
  30           focused on timer events and does not do any interactivity boosting.
  31
  32           Some workloads benefit from using it and it generally should be safe
  33           to use.  Say Y here if you are not happy with the alternatives.
