Hello List! What are the current best practices for creating periodic threads with real-time Linux? Do folks primarily use timerfd? Do folks primarily use POSIX timers and sigwait? On a somewhat related topic... how do folks stagger the startup of periodic threads? For example, suppose one (high priority) thread needs to run every 20ms, only takes 1ms to do its work, but _really_ needs to run on that 20ms clock. Now suppose some other thread needs 4ms out of every 20ms to accomplish it's work. If it were to start 9ms after the first thread started, then every 10ms one thread or the other would run, leaving 15ms for non-realtime (or lower priority real time) threads to run. I can imagine any number of home-grown solutions to manage the staggered startup of these two threads. I am wondering if there is a more standard way to do this. Any thoughts? --wpd -- 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
