Official realtime kernel

Feature state

openSUSE-11.2
Rejected Information
openSUSE-11.3
Rejected Information

Description

There is no official kernel-rt and kernel-rt-source in main repository (and main update).

Realtime kernel is very important for audio workers and those, who need very fast responses.

There are third party packages, but official support for realtime kernel would be much better.

Please see the openSUSE news article:

People of openSUSE: Jan Engelhardt

it explains why it is not included in openSUSE 11.1.

At the openSUSE Conf 2009, it was mentioned that SUSE focuses rather on Server RT usage than Desktop RT usage.

Hi Folks,
I would like to see official support for a desktop real-time kernel too. Again, for those of us who which to use suse as a base system for a digital audio workstation.
I'm interested in reviving the JackLab Audio Distribution after I finish my thesis but for now I'd like to be able to play around with audio programmes aided by an -rt kernel.
Currently, there is a kernel-rt package for 11.3 in the oss repo but it is at version 2.6.31, whereas kernel-desktop is at version 2.6.34.7. So I'm thinking that the kernel-rt is unlikely to be a drop-in replacement here. I've had a look at Jan Engelhardt's good work but even his latest kernel-rt is at 2.6.33.7. So what to do?

Many thanks to all in advance.

Please, please, please add an official real time kernel to openSUSE 11.3 and the forth coming 11.4.

This is a must for digital audio workstations...

And where is the manpower supposed to come from? Given upstream did not produce rt patchsets for >2.6.33 yet, there won't be any rt in 11.4.

My apologies, I didn't understand the problem when I made my comments above. I'm just a user, not a developer.

I had previously assumed that the packaging of kernel-rt had simply either been forgotten about or left out of the distribution, given its rather niche user base. I've since had a look the Real-Time Linux Wiki page [
https://rt.wiki.kernel.org/index.php/Main_Page] and there are indeed no rt patchsets available for kernel versions greater than 2.6.33. Without these, I agree that it would take up a lot of developer effort for not much return.

So what is the best course of action to get updated patchsets? Post to the linux kernel mailing list, post to the kernel newbies mailing list or contact the individual maintainers of the rt patch? I'm conscious of not wanting to spam a whole list with a niche interest or sound like I'm expecting people to jump to it when they may have other projects on the boil and I have had zero involvement with kernel development to date.

It's worth pointing out that kernel-rt seems to be still in active development, as a code commitment was made as recently as 21st December, 2010.

Like always - if talk does not spur on someone to your liking, you may need to consider shopping instead.
