Dear all, I am running some latency tests with irqbench/irqloop. I am wondering whether it would be possible to achieve better results when activating CONFIG_PREEMPT and CONFIG_PREEMPT_VOLUNTARILY during the kernel configuration and running irqloop in User Mode over this kernel? Does it make any sense? I think in theory it should give better results because this irqloop runs in secondary(linux) domain when started, right? An increasing preemptibility of the linux kernel should be better for the irqloop-task. All tests were made under heavy I/O and CPU load by means of "dd", "pingflood" and "cpuburn". Nevertheless, I can only achieve worse results when activating CONFIG_PREEMPT.
Thanks in advance and regards, Markus Franke _______________________________________________ Xenomai-help mailing list [email protected] https://mail.gna.org/listinfo/xenomai-help
