Abstract
Rapid Reaction Linux has been created at the University
of German Federal Armed Forces in order to en-hance
realtime capabilities of the standard Linux kernel.
Rapid Reaction Linux combines two well known patches
to achieve this goal on the Intel x86 architecture using
processors like Intel Pentium or any newer descendant.
Rapid Reaction Linux combines the LOWLATENCY
Patch [Molnar00], provided by Ingo Molnar, which has
been found to reduce long latencies in the Linux kernel,
with the UTIME Patch [Kansas97] of Kansas University
that improves the precision of standard Linux timing services.
Rapid Reaction Linux is not related to the well
known KURT Linux [KURT98], except for the UTIME
patch, both systems are relying on.
