Dear Mehdi,

thanks for your interest in LITMUS^RT. None of the current plugins currently supports this, but it wouldn't be difficult to come up with a plugin that does. For instance, you could easily hack the P-FP plugin to support some kind of thread migration where you change the priority on every migration.

Best regards,
