NOTE: This page is outdated, dynamic ticks are now supported in
the mainline Linux kernel, see CONFIG_NO_HZ.

Dynamic Tick Timer for Linux (dyn-tick) makes the HZ dynamic. When
using dyn-tick, the system runs at full HZ during load, and skips
ticks when possible while idle.

This allows extra power saving measures to be taken during the longer
idle periods. On a PC, the HZ can vary between 6Hz during idle and
1000Hz during load.

Dyn-tick was originally implemented for TI's OMAP ARM architecture,
and has been in use in the linux-omap tree since October 2004.

Dyn-tick is based on earlier similar implementations, mostly
on the 2.4 VST patch of the Linux High Resolution Timers project,
and 2.6 s390 NO_IDLE_HZ patch.
