Re: newbie question: vchiq not working with RT_PREEMPT kerne

Last time I tried to do this it failed badly point 1, in the mmc driver loading.
I used the kernel 3.2.27 (c58d10edc9fb05282128e58d3acb589010a72281).
I'd guess RT_PREEMPT doesn't work properly on 3.2 rpi kernel. Though it could be working in future version which should be more "upstreamed".

Re: MATLAB

MATLAB 2013a brings a proper support for Simulink on RPi, and the expensive Simulink Coder is not needed anymore. Reading the documentation looks like you have to install a cusom raspian to be able to run Simulink models. Unfortunately Windows is the only host supported, which is quite surprising to...

Re: does the wheezy beta kernel have PREEMPT??

I haven't tried yet what A7thStone did, but a few weeks ago I tried to patch the rasperry pi kernel code 3.2.27 with the rt40 patch. It applies fine, and compiles, too but it doesn't boot. I think it's related to the mmc which gets broken by the patch. I guess it is due to some bcm driver not in mai...

Re: does the wheezy beta kernel have PREEMPT??

Great news!
Are you compiling vanilla kernel?
At https://github.com/raspberrypi/linux I see that the newest one patched for rpi is 3.2.27, are you applying these patches too?

Re: does the wheezy beta kernel have PREEMPT??

This is great news, could you post the config file that you used?
I would like to make some customization so I can't use your binary.
By the way which kernel sources have you used?
https://github.com/raspberrypi/linux this repo goes up to 3.2.27.
