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>
being suitable (quite) for "hard RT" tasks.<br>

if someone needs such a kernel for debian, they are

I tried that once. Booting it just led to panics. I decided it
didn't like my hardware for whatever reason.<br>
<br>
I'm doing ok with the stock Debian Sid kernel, but I don't
need latency as low as others might.</blockquote>

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" target="_blank">kernel.org</a><br>
Patch according to your release ( <a href="http://www.kernel.org/pub/linux/kernel/projects/rt/" target="_blank">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" target="_blank">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>

Hi, I'm using Debian Wheezy.<br>
I'm not comfortable in building kernel on my own, so I try Liquorix,
that hasn't the RT patch, but is built with the kernel system timer
set to 1000 hz (instead of the standard 250 hz), and that seems to
improve the midi timing. (I read this somewhere in Rosengarden site,
can anyone confirm this?)<br>
I work mostly with midi and samplers, so with rtirq and Liquorix it
seems enough for me. <br>
Are there better kernels for audio/midi operations in Wheezy? <br><font color="#888888">
