Is this with a slower or single core machine ? ------------------------------ Message: 2 Date: Wed, 27 Apr 2011 14:08:28 +0000 From: William Blackburn <bill_-(a)hotmail.com&gt; Subject: [Fedora-music-list] Looking to get involved To: <music(a)lists.fedoraproject.org&gt; Message-ID: <SNT133-w2589D123B7F372F49C9D39B6980(a)phx.gbl&gt; Content-Type: text/plain; charset="iso-8859-1" Hello, you guys have most likely seen me on this before when I was asking questions about something. However, I have been using Fedora for a while now and I would like begin to get involved with the music community. I am looking to maybe learn how to package things or to do anything that would help out. Basically, I want to be part of the team. I wrote a wiki in the past but it has since been obsoleted. This is the link. https://fedoraproject.org/wiki/User:Tertl3/real-time What could I do to help out? Thanks a lot everyone!

Oh yeah.... I would love that! > All the music packages in the world wont matter if running JACK at lowest latency requires building your own kernel. When I use Fedora for audio that's what I have to do - build my own kernel from upstream source. Any particular reason you don't use the rt patched kernels I build for Planet CCRMA? (apart from not wanting to use a non-Fedora repository, of course). Just curious... > Building the real time kernel is the easy part. Navigating the Fedora project's labyrinthine structure and packaging requirements are the hard part. Yes, packaging an rt kernel is not easy, at least when you start... I've been doing that since 2001 (sigh!). Last time the subject of "rt kernels into Fedora" came up (2008 I believe), there was no interest from Fedora or RedHat into getting a second kernel into their repositories - and the question had already been asked two years or so before _that_. I could try to dig up the thread. Maybe things have changed, but I don't hold much hope till the issue is forced by rt getting into upstream (real soon now? :-). And then the big discussion will be "should we enable this in the build - it will break things!"? I don't see how Fedora would manage two kernels with the support issues that would surface specially since today the latest "official" rt patches are for 2.6.33 (I'm testing a forward port to 2.6.34 that appeared in the rt mailing list, but that is still old). -- Fernando > If you know anything about RPM packaging and/or getting packages into Fedora I would highly encourage you to look into this.

I recommend the following tutorial: http://mywiki.wooledge.org/BashGuide In addition to adding new packages to our repertoire, we also need help with the existing packages. If you follow the instructions to become a packager, you will come to a stage where you need to find a sponsor. Let me know if/when that happens.
