 	  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.

+	  This cpuidle governor evaluates all available states and chooses the
+	  deepest state that meets all of the following constraints: BM activity,
+	  expected time until next timer interrupt, and last break event time
+	  delta.  It is designed to minimize power consumption.  Currently
+	  dynticks is required.
