Zen Sources: The Way Kernels Should Be

Posted in Linux, Open Source by Rahul on August 31, 2009

EDIT: New Location for post and the blog.

From the main site, which can be found here.

Zen-Sources is a collaborative effort of kernel hackers and enthusiasts to provide the best Linux kernel possible. We include code that is not yet found in the mainline kernel in an attempt to support the latest hardware, new features, security fixes, optimizations, etc.

Now, on to the important stuff:

  1. Installation Guide for Gentoo Linux. (here). I recommend following the hand based git setup. (here).
  2. Arch Linux Install Guide (here).
  3. Ubuntu Guide. (here).
  4. For other distros, see the git mentioned in 1. (or check the repos and forums forums for your distro)

As you might have guessed from my recommendation, I have been using the git based setup on my Gentoo Linux install as my primary kernel. It has worked for me most of the time (there have been instances where the use of a kernel in rc stages has induced a bug or two – but this has seldom been the case and there is always the possibility to switch back to the stable release of zen sources).

There is a long list of projects that are included in zen sources (see the full list here) but the major advantages that I would think worth mentioning are:

  • Zen Tune
  • Brain Fuck Scheduler (don’t judge on the name)
  • BFQ
  • No problem with suspend/hibernate (and this is without TuxOnIce)

I would definitely suggest everyone to have a go at this. You will like it.

    I don’t know If I said it already but …Excellent site, keep up the good work. I read a lot of blogs on a daily basis and for the most part, people lack substance but, I just wanted to make a quick comment to say I’m glad I found your blog. Thanks, 🙂

    A definite great read..Tony Brown

    Interesting findings Rahul.

    Since you use it, will you have some benchies on it and share some results with us?
    Like testing gentoo “default kernel” vs “your tweaked zen kernel” with, say, phoronix test suite or something?

    Hmm, the idea is not bad.

    What I would do is this:

    Download vanilla-sources, copy the zen config over there (stuff that is exclusive to zen would obviously disappear in vanilla) and compare the two.

    Expect a detailed post within a week.
