</div>Dear Sisu,<br>
<br>
LITMUS^RT's PSN-EDF plugin will admit tasks only if they are already pinned to the correct CPU. You should use Linux's standard methods for moving tasks to a specific processor before transitioning into real-time mode. liblitmus provides a bunch of convenience wrappers for this (have a look at migrate.h). For example, be_migrat_to_cpu(123) would migrate your task to processor 123 and pin it there.<br>
<br>
If you run into any issues in your experiments, please let us know.<br>
<br>
Best regards,<br>
Björn<br>
