Anyone knows if the paid OSes have this?

  Well, if your RedHat and are paying someone to work on this feature in Linux, then yes. [1] Irrespective of my disclaimer, many companies are investing many smart people in making Linux work well. Anyway, I've heard rumors that Windows 8 has this, but I can't find a good source on that (admittedly, I'm spoiled with GNU/Linux where it does not take much work to find this stuff). [1] I just pieced this together, so take it with a grain of salt. Following the e-mail at [2], I guessed that Frederic Weisbecker was running this project. Googling him brought me to his github profile [3] which indicates he is with RedHat. Anyone who actually knows what is going on please confirm or correct this.

  Windows 8 pushes out the tick. See "Idle Hygiene" here: http://blogs.msdn.com/b/b8/archive/2011/11/08/building-a-power-smart-general-purpose-windows.aspx http://blogs.msdn.com/b/b8/archive/2011/11/08/building-a-pow...

    You sure about that? I read that section and it seems to be about idle duration whereas this is about turning off the timer interrupt on non-idle CPUs.

      You're right, FULL_NO_HZ isn't mentioned in the blog I linked. It's more similar to CONFIG_NO_HZ.
