Hi,

Hi all,

after Andreas' and Guillaume's great HOWTO, I finally pulled out my raspi over the weekend and played with it.

It works pretty well. However, the system is pretty unstable with the 3.1 kernel. I noticed when trying to build ffmpeg from source. Lots of strange errors, from ext4 complaining about delayed allocation to spurios "ENOPERM" when closing temporary files during compilation etc. Also, the raspberrypi-gfx demo/test tools did not work, erroring with messages about "vcihq not connected" in dmesg.

Additionally, my 512MB Raspi only had 256MB available, no matter what amount of gpu_mem I put into config.txt.

Then I simply grabbed the binary kernel and modules from https://github.com/raspberrypi/linux and new firmware from https://github.com/raspberrypi/firmware and voila -- the little box was running stable.

So I took the kernel from devel:ARM:Factory:Contrib:RaspberryPi:kernel-3.6 and updated the patch set to yesterdays git and changed the configuration to be pretty similar to what is in the "upstream" git.

Sounds good. :)

...

I also updated the firmware package.

Both together run very fine for me. I have all RAM available, the test tools work, etc.pp.

So maybe it would make sense to use the 3.6.11 kernel as "upstream" Raspberry Pi also does?

Make sense to me.

...

I created SRs 198076 (raspberrypi-firmware) and 198080 (kernel-raspberrypi) and maybe we should use devel:ARM:Factory:Contrib:RaspberryPi:kernel-3.6 as the default raspi kernel?

I accepted your firmware patch but I have not the rigths to accept kernel SR.

Well, if nobody objects, I could just SR it to Contrib:Raspi (without :kernel-3.6 subproject), but I'd wait for comments before doing so :-)

If it is accepted to Contrib:RPi, then we could remove :kernel-3.6 subproject

...

Thanks for your help.

Actually, I sort of promised Alex at the Chemnitz Linux Days in spring that I would try to get openSUSE on Raspi into good shape, but unfortunately got always sidetracked. So helping out now that the hard work is done is the least I can do :-)

Alex, thanks for the recruitment! ;)

Best regards,

Stefan

P.S: I built the kernel in home:seife:ARM so you can take it from there for testing.

Will try it tomorow. Guillaume -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
