2) the PREEMPT_RT kernel is substantially "more realtime" than any<br>
version of windows or OS X that you could lay your hands on. its more<br>
like an actual realtime OS than the kind of general purpose OS that<br>
regular Linux, Windows and OS X represent, though without actually<br>

if someone needs such a kernel for debian, they are available at<br>

I tried that once. Booting it just led to panics. I decided it didn't like my hardware for whatever reason.<br>

I'm doing ok with the stock Debian Sid kernel, but I don't need latency as low as others might.</blockquote><div><br>Just to spread some KISS :-) <br>Compiling a debian RT kernel is quite straightforward.<br><br>
Download debian sources or vanilla ones from <a href="http://kernel.org">kernel.org</a><br>Patch according to your release ( <a href="http://www.kernel.org/pub/linux/kernel/projects/rt/">http://www.kernel.org/pub/linux/kernel/projects/rt/</a> )<br>
<br>Run `make oldconfig` inside the sources dir, you will probably be asked about configs in the newer kernel not found in .config-YOUR_RUNNING_KERNEL<br><br>Then follow the common workflow, run `make menuconfig`, at least change only the PREEMPT opt and seti it to 'complete preemption'.<br>
<br>Create your linux-image debian package with make-kpkg (<a href="http://www.debian.org/releases/stable/i386/ch08s06.html.en">http://www.debian.org/releases/stable/i386/ch08s06.html.en</a>)<br><br>If your running kernel works this one will too 99.9%<br>
