kernel26-ice, RT update/option

ngoonee · 2009-05-03 08:33:24

The below is now outdated, because I've just submitted the kernel26-rt-ice package to the AUR and will be maintaining it. It can be found here. Please use this thread for support request/questions. Of course, AFTER googling/searching the wiki/forums.

Hi all,

Please let me draw your attention to kernel26-ice, maintained by iceman81. Since 14-Apr-09, the RT patch has been tacked on to that kernel, and can be applied simply by changing a single variable in the PKGBUILD.

However, the kernel is first and foremost and ICE kernel, so updates to the RT version will not be reflected by a changed version number. In other words, yaourt will not notify you its been updated, so on and so forth. So, the purpose of this thread is so that you can be informed everytime there is an update to the RT patch, as applied to kernel26-ice. I'm responsible for the thread, and will simply post a message here everytime there is an update, so subscribe here if you like.

Note: Please simply click 'Subscribe to this topic' right at the bottom (its above the Quick post region, on the left) instead of replying to subscribe, so that subscribers do not receive non-related notifications. Thank you all for your cooperation, and iceman81 for your maintainance of the ice, and now the RT, kernels.

Throughout the lifespan of 2.6.30 there was no workable -rt kernel. This will likely recur at 2.6.32. Because of that, I'll be keeping here a record of the last working PKGBUILD I have used from kernel26-ice, with the appropriate modifications for RT. I do not want to maintain a separate PKGBUILD on the AUR, as this is iceman81's project, and I do not have the skills to do more than modify his builds.

FOR NVIDIA USERS:- Currently (22-Sep-09) nvidia drivers cannot compile on the above kernel. I have uploaded the following package - nvidia-beta-ice-rt which applies the appropriate patches to the latest nvidia-beta non-free drivers to allow them to compile on this RT kernel. Please post bug-reports here or in the comments.

2.6.29.3 rt13 is out, and has been updated by iceman81

ngoonee · 2009-06-14 14:52:23

So far we're up to 2.6.29.4 rt16, the last few releases have resulted in a package version change so I didn't bother to update. 2.6.30 probably coming out soon, so if the rt patch for that is slow please expect breakage for a while.

ngoonee · 2009-09-14 00:57:35

We are now at 2.6.31. No working rt patch for 2.6.30 was found, so this is the first new RT patch in kernel26-ice in 3 months. I'm downloading the sources now, if the compile goes fine I'll paste the PKGBUILD in the OP. This is so that, if in future kernel versions when -ice moves ahead -rt is left behind there will be a reference PKGBUILD for those who still want the RT kernel.

I've considered doing an AUR package, but there's already one old one by Fackamoto i believe, so unless that is orphaned this topic will be the 'distribution' channel for RT via kernel26-ice.

EDIT: Does not work, the patch is for rc8 and I believe there have been changes since then. Will continue trying for when new patches are forthcoming.

The current PKGBUILD works. In a while I'll post up the working PKGBUILD for posterity.

Point to note, I could not use the binary Nvidia driver with this kernel.

iceman81 · 2009-09-18 16:19:57

What's the problem with the nvidia drivers?

ngoonee · 2009-09-18 16:50:21

Only for the rt-patched, iceman81. kernel26-ice works fine with binary nvidia. The RT ML has some patches for the nvidia installer, but I haven't tried applying them yet, and they're not for my version of the nvidia installer.

If you are interested you could manage nvidia-ice package to add the support for rt kernel, using a variable like i did in the kernel pkgbuild

ngoonee · 2009-09-19 22:38:08

I know that, but I haven't even gotten it to work on my own machine yet . Not a top priority at the moment (no music-related work to do as of now), but I do want it working eventually so will come aroundn to that.

ngoonee · 2009-09-22 12:19:28

Have done as you suggested to upload the nvidia installer to AUR. Links as well as a saved copy of your PKGBUILD are available in OP.

ngoonee · 2009-11-10 04:07:30

Submitted a kernel26-rt-ice package, updating first post to reflect that.
