As I understand, it will be integrated into 2.1.XX kernel after cleaning up
SMP stuff. For now, there is a separate patch and utils for 2.0.27
( ).

But there is also:

Title: rt - run program on realtime priority
Version: 1.0
Entered-date: 12 Jan 1997
Description: rt starts any program on realtime priority, like nice
does with lower priority. Lets you choose scheduler
class (SCHED_RR vs SCHED_FIFO policy) and priority.
Keywords: linux, real time, scheduler
Author: Boris Tobotras <>
Maintained-by: Boris Tobotras <>
Primary-site: /pub/Linux/system/Admin
10 kb rt-1.0.tar.gz
Alternate-site: /pub/Linux/local
10 kb rt-1.0.tar.gz
Platform: Linux 1.3.87 and later
Copying-policy: GPL

But it does something else. I do not know how well it really works.
