That pulls my curiosity trigger because one of my hobbies is CNC<br>
machinery, and its realtime demands are far more stringent than some .1<br>
millisecond accurate audio delivery. Currently we are running linuxcnc on<br>
2.6.32-122-RTAI, but that RTAI patch is invasive as hell, [ ... ]<br>

If SteamOS is claiming real time, just how "realtime" is it? <br></blockquote><div><br></div><div>There is no comparing even the RT kernel with RTAI. They are totally different conceptions. RTAI is basically a microkernel that runs a normal kernel as a client. It requires drivers for every device that is included in "realtime land" (i.e. for audio, you cannot use ALSA, you would need new drivers that run in the RT executive.<br>
<br>SteamOS *might* use the RT kernel, but I'd be incredibly surprised if they even considered RTAI.<br><br></div><div>--p<br><br></div><div>(disclaimer: i haven't looked at RTAI for quite a long time, things might have changed)<br>
