5 ``intel_idle`` CPU Idle Time Management Driver
16 ``intel_idle`` is a part of the
22 firmware.  [To understand ``intel_idle`` it is necessary to know how ``CPUIdle``
26 ``intel_idle`` uses the ``MWAIT`` instruction to inform the processor that the

37 ``intel_idle`` is not modular, so it cannot be unloaded, which means that the
