Re: [Xenomai-help] Preemptive scheduling

Hi Philippe,

I appreciate your help very much! I found and applied the diffs of changeset r2092. It seems to work much better now: The system is able to access the hard disk, as I see the LED blinking periodically. That`s great!

Still, I can`t use the keyboard to stop the application by pressing Strg-C. Also, the text cursor doesn`t blink, so the Linux system seems to be overloaded (probably, it`s no longer scheduled).

So, the Linux-Kernel now seems to be able to run on behalf of a high-priority task. Though, it is no longer scheduled as an idle task, which is ok as there is the higher priority-task with the infinite loop. This way, everything acts as expected.

Nevertheless, it would be interesting to run a linux shell concurrently. Can I adjust linux priority during runtime (or: where do I have to adjust it in the sources)?

And btw, where can I look up the keyboard interrupt`s priority (is it kernel`s priority)?

Thanks a lot,

Jack
