This option has been selected from arch code as it was assumed that it's necessary to support oneshot mode clockevent devices. But it's just a core internal helper to compile tick-oneshot.c if NOHZ or HIG_RES_TIMERS are selected.

This option enables a tickless system: timer interrupts will

only trigger on an as-needed basis both when the system is

busy and when the system is idle.

This option enables high resolution timer support. If your
