I posted some test code with two threads and a shared PTHREAD_PRIO_INHERIT mutex. It forces repeated priority boosting from SCHED_OTHER to SCHED_RR and then spins for a bit while boosted. It eventually receives a SIGXCPU on non-fixed kernels. The SIGXCPU happens much faster with a CONFIG_PREEMPT_RT kernel, and does happen eventually with CONFIG_PREEMPT_VOLUNTARY kernels. > > Sebastian Thanks, Brian -- To unsubscribe from this list: send the line "unsubscribe linux-rt-users" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
