An idle CPU that is not receiving scheduling-clock interrupts is said to be “dyntick-idle”, “in dyntick-idle mode”, “in nohz mode”, or “running tickless”.

The nohz parameter is mainly used to reduce timer interrupts happening on idle CPUs. This helps battery life by allowing the idle CPUs to run in reduced power mode.

Mar 20, 2012 · NOHZ does not cause processes to get scheduled less often, because it only kicks in when the CPU is idle - in other words, when no processes are schedulable.
