hi,
i want to get a low-latency-kernel-source to mod it like i want.
what do i need (which source / which patches / which version / which config)
or where can i get a kernel-source where low-latency is implemented?
thanx
mike

Assuming you have a running linux system and you know how to compile a
kernel here's what you could do:
1) Get the latest patch here (put it in /usr/src/):
http://www.kernel.org/pub/linux/kernel/projects/rt/
I'd go for
http://www.kernel.org/pub/linux/kernel/projects/rt/patch-2.6.24.4-rt4.bz2
2) Get the matching kernel source (so for the above patch you need
2.6.24.4) at kernel.org and put it in /usr/src/. Also make a symlink
from /usr/src/linux to your source
3) Apply the patch with:
cd /usr/src/linux
patch --dry-run -p1 < ../patch-2.6.24.4-rt4
The above command (with --dry-run) doesn't apply anything, just reports
what will be done. So if you don't get any errors (and you shouldn't)
you run it again without "--dry-run":
patch -p1 < ../patch-2.6.24.4-rt4
4) Copy the latest working .config into /usr/src/linux, on debian/ubuntu
it can be found in /boot/config-KERNEL-VERSION.
5) Configure your kernel with "make gconfig" (that's what I prefer). It
needs some gtk-devel packages installed, I always forget which, but
google knows.
6) Compile + reboot + make music :-)

i would also like to mention "make oldconfig". This only asks you the new
configuration questions introduced by the patch...

Might be a good idea. I think the patched kernel will have sensible
configuration, though.

Good point. But that's another story. At least the initial poster only
asked for help with patching and compiling the kernel.

Now I doubt the author would be able to go through this without further
reading. In any case, one could've found these via Google:
http://gentoo-wiki.com/HOWTO_Compile_a_Kernel_Manually
http://www.falkotimme.com/howtos/debian_kernel2.6_compile/
http://howtoforge.com/kernel_compilation_fedora
And basically searching in the following will yield better results:
http://howtoforge.com/trip_search
Referencing a buildscript might help too (relevant commands to run are in
build function):
http://aur.archlinux.org/packages/kernel26rt/kernel26rt/PKGBUILD
