  16           This option enables a tickless system: timer interrupts will
  17           only trigger on an as-needed basis both when the system is
  18           busy and when the system is idle.

  23         select TICK_ONESHOT
  24         help
  25           This option enables high resolution timer support. If your
  26           hardware is not capable then this option only increases
  27           the size of the kernel image.
