dyntick in 2.6.6

Parent article: Clockevents and dyntick

Just as a historic side note, support for disabling the timer tick during
idle was first merged three years ago for the s390 architecture, see
http://lwn.net/Articles/82378/. The first lwn coverage I could find on the
topic is http://lwn.net/2001/0412/bigpage.php3#kernel, another three years
earlier, with a patch against the 2.4.3 kernel.

dyntick in 2.6.6

IBM was pretty big on the tickless kernel idea quite awhile ago, probably due to their emphasis on hypervisors and virtualization. Separately, the ARM branch has been big on it for the embedded space.

It looks like the major difference is that clockevents gives an abstraction layer for the clock. Once all the arches are synced up to that, I wonder if dyntick becomes the default?
