Question about rtirq
 
Hi Rui :)
hi 64 Studio list :)

the default kernel for 64 Studio is the 2.6.29-1-multimedia-amd64. I
like to be able to run the default kernel and the latest 2.6.31.6-rt19.

I guess I need to upgrade rtirq to be fine with the latest kernel? Will
it be fine with 2.6.29 too?

Do I need to include both scripts in one script?
quasi ...
if uname -r = 2.6.29 then go on with old script
if uname -r = 2.6.31 then go on with new script

Cheers,
Ralf

What is rtirq.spec for?

Should I only move rtirq.conf to /etc/default (there it is for 64
Studio, renamed to rtirq) and move rtirq.sh to /etc/init.d (renamed to
rtirq) or is there something additional to do by using rtirq.spec?

Cheers,
Ralf

Thank you :)

"RTIRQ_NAME_LIST="rtc snd usb3 i8042"". I guess it would be wise to try
usb with or without port number at first when the USB MIDI interface is
important, followed by snd and i8042, while rtc could be at the last
position when running hpet. Dunno?
