As promised, Valve has released the first test release of SteamOS. From the FAQ:

SteamOS is a fork (derivative) of Debian GNU/Linux. The first version (SteamOS 1.0) is called 'alchemist' and it is based on the Debian 'wheezy' (stable 7.1) distribution.

The major changes made in SteamOS are:

  • Backported eglibc 2.17 from Debian testing
  • Added various third-party drivers and updated graphics stack (Intel and AMD graphics support still being worked on)
  • Updated kernel tracking the 3.10 longterm branch (currently 3.10.11)
  • Custom graphics compositor designed to provide a seamless transition between Steam, its games and the SteamOS system overlay
  • Configured to auto-update from the Valve SteamOS repositories

You need to have an NVIDIA card for it to work, since Intel and AMD graphics are currently not yet supported (work is underway).

From my perspective, this is not a LFS-based project, the kernel was fine-tuned for gaming and not just by a random geeks, but engineers from Valve, where you cannot replicate their skills easily, you need at least their level of expertise to do the job. And that is massive. This is not about how much lines of code you added or subtracted from a vanilla Debian kernel, but the quality of code that is needed.

And I am excited also for their works on audio, since this can greatly benefit musicians who are using Linux.


RT kernels have existed for audio work for a long time on Linux. Most of the patches Valve added to their kernel are in fact longterm existing ones like the RT tree. More and more of the RT tree is ending up mainline.

The major difference between valve kernel and standard Distributions RT kernels is tuning. There are a few options like one of Intel power mangement options that is disabled.

Basically you can be given the best kernel on earth but if you cannot configure it correctly it worthless.
