Well......I did it. Finally after much ado it's ready. Have a look:

http://mzilikazi.sexypenguins.com/

You can even Browse the repo directly

My intentions are to build rt kernels as patchces are made available (or as rt is incorporated into the main kernel tree). I have not yet decide which flavors will be built but for the moment I think i686, P4 & K8 will be included. Also undecided is how many modules will be built against each kernel, afterall most people will not need all the modules supplied with a standard Kanotix kernel. It's also quite simple to build any modules you might need with module-assistant.

Currently I'm building cloop, squashfs & unionfs modules.
Why? Well they are required for debian-live (although I cannot get the rt kernel to work w/ debian-live just yet).

If you're interested in music production and want to try realtime Linux give one of the kernels a try. Make sure you also edit /etc/security/limits.conf or realtime will not work.

Please let me know if you have any issues.
Don't be too hard on me now this is my first Debian repo. Winken
And NO HTML is not my specialty.

ENJOY!

I installed 2.6.18-rt7-p4 last night and it seems to be working fine.
Nice work MZ.

just one remark: does an RT kernel benefit ordinary users? i.e.: will I have to install jackd? Or will plainly exchanging the kernel be of any good? The only thing springing up to my mind when hearing RT is, I really dislike alsa's lag when e.g. shutting down BMP (the music plays on for half a second).

First let me say IANAKE (I am not a kernel expert).

Does an RT kernel benefit ordinary users?
Probably not.
Will an RT kernel resolve your BMP issue? Dunno - never had that problem. I like Audacious - the GTK2 version of XMMS we have been waiting for.

jackd is not required in order to use an rt kernel. An rt kernel is not required for you to use jackd. jackd simply allows you to chain multiple devices/applications together in software. Some audio apps are not jack capable and yet they work fine w/ an rt kernel. If you have an rt kernel then you may start jackd in realtime.

A realtime kernel can be used for several reasons. I'm interested in low latency for music production. When I'm recording a guitar for example I want nothing to cause my audio to drop, stop or stutter. Also, since I use an effects rack (jack-rack) the time it takes the audio to pass from my guitar, into the soundcard, through the rack and out the speakers is critical. Any delay in the audio processing signal makes it sound as though I strum the guitar one moment and 2 seconds later the sound finally finds its way out the speakers (headphones). Quite unnerving! Smilie This is exactly the kind of latency we wish to avoid. The problem is only worsened when you start recording multiple tracks. Any shift in time or drop in audio causes your tracks to no longer be in time with each other or worse, to have a gap. Well.... obviously that's not going to work.

Some will say that an rt kernel is no good for a desktop. I personally use only an rt kernel on both of my desktops (AMD64 3200 & PIII 800MHz) and have very acceptable performance on both machines with the rt kernel. I'd have to do some serious benchamarking to find any major performance differences between an rt kernel and a non-rt kernel. It simply isn't noticeable to me.

It is of course entirely possible to boot 2 different kernels, one for rt the other for a desktop. The only issue here is 3D drivers. If however you install the Nvidia driver the Debian way you will not have this issue. I don't use ATI so I can't comment that driver.

You can find a myriad of info on rt kernels. Some people say that audio production can be done with a standard kernel. I disagree completely with that statement. Sure you can do pretty good but if you really need the lowest latency possible you'll like the rt kernel. Smilie

Right about now a pipe organist would be calling you a pussy MZ. The sound comes out of the pipes quite a long time after they hit the key. Winken Don't ask me how they do it, it does my head in.
You're quite right but, there is nothing worse than latency when recording. My number one complaint with Windows was latency and stuttering. What was the point of owning an expensive piece of software like cubase when the OS wasn't up to the task of running it? It ran better on an Atari.
I find that strange things can happen to non-rt apps when using a rt kernel but nothing drastic. They just get lower priority. A normal kernel is better for day to day use but if you want to record stuff in realtime then the rt patch is worth it's weight in yak fat. You just have to decide where your priorities lie. The machine I record with has the rt patch but that's the only one that does.

@mzilikazi: thanks, so I guess I can live without it. Will try audacious, though.

@Cathbard: I've heard of churches big enough that skilled organists can play canons with themselves Smilie

hello mzilikazi
I like your repostory , and your tread in general suport give me the posibility to build my on rt-kernels thanks therfor. If you are intresting in midi production to, please have a look in german forum. I have post there a script (with GUI)for using and managing SF2 files for the MIDI-Wave-Tables and TiMidity++, it will work in english to (I have let it translate from a friend, its not so stupit english like my speak here I hope).

i hope you enjoy it
