Is there a particular QNX binary that you want to run, that doesn't depend on the hard-real-time response that QNX provides? Or are you discussing a project to actually add the tweaks to FreeBSD to make it sufficiently realtime, and then add a QNX message API on top of that, as an emulation layer? > And other than using it, would anyone be interested in > helping out? I could be interested in realtime-ifying FreeBSD (or NetBSD). I believe that the SMP stuff goes a long way towards that, but I don't know what else is required. At a guess it would involve a different scheduler and a different sense of what process priorities mean. Dunno how much time I can devote though. (epsilon, probably). > Another thing, anyone knows what is the binary format? I think QNX uses GCC, so probably ELF, these days? -- Andrew To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-realtime" in the body of the message
