They have a micro-kernel , which is basically a core real tie\me kernel, which sits on top of the vanilla linux kernel. This way, all the real time tasks are handled by the Microkernel during whcih time Linux kernel runs as an idle process. Only when no RT tasks are present, the vanilla Linux kernel executes all the non-RT tasks. This way, RT behaviour is accomplished without having to modify the core Linux kernel. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
Yes, may be the poster is looking for RTLinux kind of thing. -- Regards, Sandeep. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
