The version installed is the same as on the
blog above (20070101), and the 2 files are installed, one
in /etc/init.d/rtirq, and the other in /etc/sysconfig/rtirq. I believe
the /etc/sysconfig directory was created when installing rtirq, as I don't
rmember it being there before. I say this because with Fedora the sysconfig
directory exists, and there is a bunch of files in it, and I remember looking
in Debian for this directory, and couldn't find it.
Well that is probably the matter. I never cared about an /etc/sysconfig
directory on debian (I changed to Debian after trying to migrate from
Red Hat 6.2 to Red Hat 7). Now I am on a powerbook g3 system and
/etc/sysconfig does not exist. I would bet a lot of money that we will
not find it on a debian i386 system neither. I think it does not exist
on debian. Actually, I got a complain about /etc/default/rtirq being not
found the first time i tried to execute rtirq.sh linked from the blog
above...
I think that boot directories are the main difference between debian and
red-hat based systems. So if package you installed (did you installed a
package? just guessing again) is not placing anything on /etc/default,
it is not surprising that rtirq does not work for you on a debian system.
I also ran sysv-rc-conf as root on Etch. The rtirq entry is there, but
runlevels 2,3,4,and5 are unchecked, so something isn't quite right here.
? I can't remember anything about sysv-rc-conf. On debian you need
update-rc.d to set bootscripts to be executed. On red hat-based systems
i think chkconfig (or so) takes care of this. If used as explained,
update-rc.d will create symbolic links to start rtirq (it may be
rtirq.sh) on runlevels 2-3-4-5 and to stop it on runlevels 0-1-6. You'll
find a directory /etc/rcX.d for each runlevel where a symbolic link
S99rtirq (or K01rtirq) will be pointing to /etc/init.d/rtirq.
/etc/init.d/rtirq must exist before creating symbolic links with update-rc.d
I
see also on the blog above that rtirq should be in /etc/default, but in the
case of Etch it isn't.
I think this is why rtirq is not working for you. It worked for me after
copying rtirq.conf file on /etc/default/rtirq, not in
/etc/sysconfig/rtirq. It seems that you somehow managed to get a red
hat/fedora package installed on a debian system? It could be wrong, even
if versions are the same... All I can say is that rtirq.sh from tarball
linked from musix blog complained about /etc/default/rtirq being not
found on my debian etch system... and that debian is not fedora. You'll
find no /etc/sysconfig directory on debian.
As I say. Realtime on Etch is working ok, but I'll go
through the same procedure on Debian Lenny (testing), and try and fix the
rtirq problem without using Rick Wright's one liner, although it's much
appreciated, and works like clockwork.
I'll post back after I've played around with realtime on Lenny a bit.
So you are getting no more xruns now? That is the real point... After
reading it, I would say that rtirq is a much more polished script than
ours. However it does not look as setting the rtc irq frequency as
explained on Florian's website.
In short:
a) please download tarball linked from musix blog.
b) untar it.
c) mv rtirq.sh /etc/init.d/rtirq
d) mv rtirq.conf /etc/default/rtirq
e) update-rc.d rtirq start 99 2 3 4 5 . stop 0 1 6 .
f) it should work at startup on any debian distro

Roman
