Ubuntu 7.10 "Gutsy Gibbon (http://www.phoronix.com/vr.php?view=11160)" is due out in just a few days and shipping with it is the Linux 2.6.22 kernel. One of the interesting additions to the Linux kernel since the 2.6.20-based Ubuntu 7.04 "Feisty Fawn (http://www.phoronix.com/vr.php?view=9546)" release has been the tickless kernel feature. If you hadn't read out tickless kernel article (
http://www.phoronix.com/vr.php?view=8963) from earlier this year, the tickless kernel feature (CONFIG_NO_HZ) is designed to improve the power efficiency especially on servers and portable devices. This CONFIG_NO_HZ feature works by enabling on-demand timer interrupts that allow a system to idle for a longer period of time and avoiding useless interrupts. This is not only designed to reduce power consumption but to allow for the system to run cooler and an extended battery-life for mobile devices.
