+ 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.
