Hi list,
for the past few months I've used Kon Coliva's kernel patches ho have all
the requisites to run jackd & Co.
http://members.optusnet.com.au/ckolivas/kernel/
But last time I checked those patches they gave me a bunch of errors
against 2.4.22, plus I notice such development seems to have slowed down
a lot.
What patches do you use to make a preemptible/lowlatency/capabilities
enabled kernel? Where do I find them? =)
thanks, bye

I run Debian and use their make-kpkg tools to build my kernels. I use
their `kernel-patch-lowlatency-2.4' patch package and just edit the
two-line capabilities patch by hand. This is described in the JACK
FAQ at <http://jackit.sourceforge.net/docs/faq.php#a5>.

I do the same with 2.6.0-test9 and apply only the capability patch. I still
need a few things before rebooting to 2.6; IIRC something like this suffice :
$ apt-get install module-init-tools
$ mkdir /sys
add these lines somewhere high in your /etc/fstab (right after your /)
none /dev/pts devpts gid=5,mode=620 0 0
none /dev/shm tmpfs defaults 0 0
none /sys sysfs defaults 0 0

I get mine from the Gentoo portage tree. I'm using aa-sources 2.4.22
ck-sources are pretty good too.

New subject: [linux-audio-user] anyone using jack with suse?
Hi there, since I'm sure I'm not the only one running suse (8.2), I'm
wondering how other suse users are running jack, are you using suse jack
rpms or have you compiled all your jack using apps from source, such as
getting the latest cvs versions of jack, rosegarden, fluid synth, etc...

Hi, I`m working with suse 8.2, I try to patch the suse kernel but that don`t
work. So I have compiled a new vanilla kernel with a preemptible,lowlatency
and capabilities patch. All sound apps I compile from source.
I don`t know much about suse 9.0. Maybe somebody know if suse has integrated
the lowlatency patch to the suse kernel?

With SuSE 8.2 it's a bit tricky, as the version of JACK included is
old enough that some recent applications won't even compile with it
(as it doesn't include the new transport API etc). But if you
install a newer JACK for the purposes of building newer apps, you'll
get into trouble with any JACK-based apps already installed that were
built against the old one, because they aren't compatible at the
protocol level.
I would probably recommend uninstalling the SuSE JACK package and
everything that depends on it, and going for the 0.90 release
instead. In my experience the packaged audio apps often don't work
as well as any you might build yourself anyway (e.g. the Rosegarden-4
package doesn't work for me as supplied in either SuSE 8.2 or 9.0 --
on 8.2 you unfortunately need to do "CXXFLAGS=-O0 ./configure" to
build Rosegarden without optimisation to work around a compiler bug).

Don't know, but I do find the stock SuSE kernel gives better audio
performance than the stock RedHat one. So it's possible they have
some of the patches.

Every distro seems to have their quirks, but I found that latency is not
the huge problem with suse that it is with a basic redhat install, but I
found that few of their distro audio apps work right, maybe Geentoo or
Mandrake are better, though I've also heard that debian is good, but a
lot of work. Anyways I wound up recompiling alsa, jack, and terminatorX,
so if I recompile rosegarden and muse, and get ardour working I should
be doing fine, I just need to recompile everything from cvs to get the
best possible experience.
