rt-app is the workload generator, right? I think the most interesting part here is the switched_from path, so you'd want the workload to include a !rt task that gets PI boosted to deadline every so often. Also, does rt-app let tasks die? Or does it spawn N tasks and lets them run jobs until the end? I think you want to put some effort in task_dead_dl() as well. After that, just make sure rt-app generates a _lot_ of tasks such that the migration thing gets used. Other than that, no, not really :-)
