Subject: [Xenomai-help] Limiting Xenomai tasks to one certain core in a dual core system
Date: Wed, 22 Nov 2006 09:27:40 +0100 (CET) [thread overview]
Message-ID: <13096879.1164184060512.JavaMail.ngmail@domain.hid> (raw)
Hi all,
I want to run Xenomai and rtnet (using RTDM) on a dual core CPU.
Using the kernel parameter isolcpus I can force the standard Linux tasks
to run on one of the cores.
The other core should be used exclusively by all real time tasks (including rtnet).
I can - of course - pass a parameter on each rt_task_create() call.
However how can I force rtnet (using RTDM) to run on this CPU core?
Is there a possibility to mask the CPUs to be used globally?
This could also avoid to pass the CPU number with each rt_task_create() call.
Thanks for any feedback on this.
Regards
Mathias
