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).

"[q]* SteamOS is using the Linux 3.10 kernel, but it's not a vanilla kernel. There's many patches added onto the Linux 3.10 kernel for SteamOS, particularly taken from the real-time patch-set and other changes. As pointed out by a Phoronix reader, "SteamOS appears to be using linux 3.10 - PREEMPT_RT_FULL (unsurprisingly) with a heavy amount of patching (282 patches for -rt in the 'all' architectures/folder, alone).


And someone above these posts was able to say, this is a minor change?

Compared to lot Distrobution kernel alterations this is a minor change. Yes I have provide a link to a debian equally messed with kernel.

Its all about prospective.

If you expect the steam customised kernel to be a good desktop kernel you have another thing coming. Linux kernel is highly customisable. The options you set do effect performance quite a bit. [/q]


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.
