Below is some of my personal thoughts/questions. * RTLinux's so called realtime extension-RTCORE **was* to address the previous issue--Linux is not realtime supported, for example, fully kernel-preemptive; posix realtime extension. * After linux 2.6, I did not see any outstanding reason that people still need to use a RTLinux **patch** to achieve realtime applications. I mean, why not just linux itself? Not needed RTCORE anymore. * From os/kernel viewpoint, it is very hard for me to position RTCORE, but a realtime patch. I mean, RTCORE is not able to be identified into any well-known os architecture. * If there is a very high performance micro-kernel, say, L4 or QNX/Neutrino, I personally think it is much better than the RTCORE stuff, which HAVE TO bind a secondary os as running time environment.
