Please forgive me if my question is not appropriate. Your question IMO is still in kernel zone....although...well, you sprang into "theoritical UNIX zone"...thus not really a kernel question. But enough the blah blah blah, and the reason blah blah, let's cut the blah blah blah and get to the business :D > I want to know if it's possible to create a real-time process with > SCHED_FIFO policy that starts running and never lets any other process > run again. The real question is: what's your understanding on the term "real time OS"? from there, probably we can help on how to achieve your goal... But to cut it short, even with -rt kernel tree, Linux kernel is not real time OS, at least not the hard real time one like QNX etc. Even though SCHED_FIFO is indeed a process whose priority is made such way that it will "override" others, still there are certain aspect that might prevent it to be called as "real time". For example, assume this application wanna receive keyboard input. Are you sure this keyboard input will be received *right away* by your application? or will it go the usual routine, thus the latency is unpredictable? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
