Hi, Should idle-exit-ts be removed from this interface. The last-idle-time and last-busy-time fields provide the same info.
4.2.11 should be removed? This spec describes this interface, but the kernel is free to set these properties any way it chooses. I am not wild about adding all of this property overhead. Did we decide the kernel would not call the idle callbacks when it thinks a CPU will not be idle very long or the system is very busy?
