The trend is rather to blur the distinction between native real-time and dual kernel approaches these days, not to downgrade to a kernel-only interrupt handler with co-routines on top. So no, there would be no rational reason to do that, not to mention the fact that if we can assess the typical latency of Xenomai over the seven architectures it runs on with the latest mainline kernels, we would be unable to compare this to anything else than x86 over a legacy kernel AFAIK. And no, I don't think that I'm going to send an inquiry to WRS for information regarding how RTL performs on other architectures. Incidentally, maybe you should ask yourself why they ship WR-Linux with PREEMPT_RT. > Regards arethe > 2011-04-06 > > ______________________________________________________________________ > arethe.rtai > _______________________________________________ > Xenomai-core mailing list > [email protected] > https://mail.gna.org/listinfo/xenomai-core -- Philippe. _______________________________________________ Xenomai-core mailing list [email protected] https://mail.gna.org/listinfo/xenomai-core
