24 CPU sleep state statistics and descriptions are retrieved from sysfs files,
26 statistics when it enters or leaves an idle state, therefore on a very idle or
38 cpupower monitor tool (cpupower\-monitor(1)) can be used to show real sleep

44 POLL idle state
46 If cpuidle is active, X86 platforms have one special idle state.
47 The POLL idle state is not a real idle state, it does not save any
48 power. Instead, a busy\-loop is executed doing nothing for a short period of
49 time. This state is used if the kernel knows that work has to be processed
50 very soon and entering any real hardware idle state may result in a slight
