Threaded interrupt handlers came out early in the discussion. This feature was merged into the mainline for the 2.6.30 kernel; it is useful in realtime situations because it allows interrupt handlers to be prioritized and scheduled like any other process.

Much of the realtime scheduling work in Linux has been based around getting the best behavior out of the POSIX realtime scheduling classes. Techniques like priority inheritance, for example, exist to ensure that the highest-priority task really can run within a bounded period of time.

In this part of the series we complete our tour of the Grace algorithmic composition environment. The Targets: Grace can format its output for the following targets and file types : * Audio - Realtime and file (WAV, AIFF, etc) * MIDI - Realtime and file (MID) * OSC - Realtime * Csound - Realtime and score file * FOMUS - File (LilyPond and others).

Linus has released the 2.6.25 kernel. After nearly three months of development and the merging of over 12,000 patches from almost 1200 developers, this kernel is now considered ready for wider use.

I just needed to express how impressed I just found myself with how well the linux kernel was working this morning. I was on my AMD X2 3800 processor (dual core, about 2-3? years old) and was simultaneously listening to some tunes on rhythmbox, watching an XVid movie, and browsing the web while emerging ( compiling for those who don’t use Gentoo) on both cores without any noticeable slowdowns in any the realtime activities I was doing!

Linux-based guitar effects processors haven't exactly been flourishing recently. Until recently, the guitar FX processors page at linux-sound.org listed twelve projects, of which the most recent maintenance date is 2006. Clearly, not a flourishing domain for Linux audio developers.

The Linux Kernel community has a proven track record of being in disagreement with - and disconnected from - the academic operating system research community from the very beginning. The famous Torvalds/Tannenbaum debate about the obsolescence of monolithic kernels is just the starting point of a long series of debates about various aspects of Linux kernel design choices."
