The point of real-time is to provide user-space with more control of what get's run, when, instead of something else - including system interrupts, etc. For instance, if networking should take a higher priority than their application, but disk i/o should take a lower one, the user needs to be able to control that. chrt is the correct approach for -rt in my opinion. -- Darren Hart IBM Linux Technology Center Realtime Linux Team - 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
