Say Y here if you are building a kernel for a desktop, embedded
or real-time system. Say N if you are unsure.
-config NO_IDLE_HZ
- bool "Dynamic tick timer"
- depends on !GENERIC_CLOCKEVENTS
- help
- Select this option if you want to disable continuous timer ticks
- and have them programmed to occur as required. This option saves
- power as the system can remain in idle state for longer.
-
- By default dynamic tick is disabled during the boot, and can be
- manually enabled with:
-
- echo 1 > /sys/devices/system/timer/timer0/dyn_tick
-
- Alternatively, if you want dynamic tick automatically enabled
- during boot, pass "dyntick=enable" via the kernel command string.
-
- Please note that dynamic tick may affect the accuracy of
- timekeeping on some platforms depending on the implementation.
- Currently at least OMAP, PXA2xx and SA11x0 platforms are known
- to have accurate timekeeping with dynamic tick.
