Of course I'd prefer realtime/rt, however the truth of the matter is that keeping up with patches, and keeping the kernel versions in sync for any one Ubuntu release is very difficult. For this reason, I'd favour the lowlatency kernel, as it would be easier to maintain, given its only configuration changes, and would be easier to get into Ubuntu, and maintain it, keeping in sync with the Ubuntu release kernel version. How do you would want help (test, packaging, upstream relation, Ubuntu relation, Studio relation and so on)? I'm happy to help maintain the low latency kernel, i.e using the Ubuntu release kernel git tree as a base, and making our own changes on top, and rebasing on the Ubuntu kernel for fixes. Can help get it into universe, and maintain it there. Which Ubuntu releases do you would want see well supported for that/those kernels? Every releases or only LTS? With the low latency kernel, I would be happy to support it for every Ubuntu release where it is in the archive.

Laurent, 2010/10/4 laurent.bellegarde laurent.bellega...@free.fr: Which are kernels on you are interested in? The -rt, -lowlatency or -realtime? Real time for audio, is there de difference beetween the three proposals ? -lowlatency == -generic + more aggressive low latency kernel configuration It can offers all things that Ubuntu offer with -generic so -backport modules, video closed drivers and so on. It is very solid and oriented to soft users. Trade-off between low latency and power consumption. -rt == -generic + plus PREEMPT_RT patchset (this is the realtime Linux) It would want offer the same but require a lot of works. it would want be aligned with -generic version but it can't be able. It isn't very solid and it is oriented to hard users only. Power consumption is a secondary concern. -realtime == vanilla (kernel.org) + plus PREEMPT_RT patchset (this is the realtime Linux) It don't be interested neither to be aligned with -generic kernel nor be compatible with all closed video rivers shipped (and worked) with Ubuntu. It don't provide -backport drivers. it is very stable and it is oriented to hard users only. Power consumption is a secondary concern.

Re: Last call (was Natty and RT Kernel)
David, 2010/10/5 David Henningsson david.hennings...@canonical.com: [...] great that you want to manage these kernels! I have always managed -rt kernels in Ubuntu since Feisty Until Maverick where I have gave up for personal reasons. I'm mostly curious about -lowlatency, but unfortunately I haven't got around to test it. I think -preempt is a server kernel? Could you also say that -lowlatency is the desktop version of -preempt? I don't know much about -preempt. A low latency kernel in server context make little sense to me at least. Is there a difference between -rt and -realtime, except that your -realtime seems more updated than -rt? Do you think we should replace the official linux-rt, with your linux-realtime? Few minutes ago I replied to Laurent about that. closely until now, so I'd also like to ask you - do you feel you have the support you need from the kernel-team's side for maintaining these kernels? Really I don't understand what you mean with feel. In any case I avoid to reply on this answer because I don't want start a flame. [...] I think we need to have it for every release, to get the best possible testing and quality of these kernels. If that's possible? The time of one-man-kernel-made is finished. So if people want the real time kernel they should help. Please reply only if you want help. Just to clarify, did you mean if you need help (you help me) or if you want to help (I help you) ? I don't need help unless you want offer me a serious job. Real time kernel need help. All -rt kernels have always worked well on my old laptop also the infamous Intrepid and Jaunty releases.

Re: Last call (was Natty and RT Kernel)
Alessio, *Which are kernels on you are interested in? *-*rt * *Which kernels you use on per day basis (so you can provide at least test and feedback)? -rt* I use the *-rt kernel on a daily basis* for both multimedia work and non-multimedia work, on my laptop, and it is very reliable for me and I never get xruns in Ardour with it. I (and probably many others on this list) do not have a good grasp of who is doing what in regards to Ubuntu Studio, but I'd like to understand more. I'd like to learn more about what is involved with getting an -rt kernel available for Ubuntu Studio and I'd be willing to help. *How do you want to help (test, packaging, upstream relation, Ubuntu relation, Studio relation and so on)? Test* Not sure what the *relation items mean, but if pointed to some educational materials, perhaps I can help with other things as well. *Which Ubuntu releases do you would want see well supported for that/those kernels? Every releases or only LTS? Preferably every release.* Alessio, what you wrote at https://help.ubuntu.com/community/UbuntuStudio/RealTimeKernel is very helpful information. Do you have any advice on where I can learn more so that I can more effectively help? * *-Erik On Mon, Oct 4, 2010 at 09:27, Alessio Igor Bogani abog...@ubuntu.comwrote: Hi, If you would want help in kernel stuff for Ubuntu Studio please reply to these questions: Which are kernels on you are interested in?
