Taming linux

Abstract

This paper describes the overall design, partial implementation and brief performance evaluation of a system in which Linux and its applications run besides real-time applications. The separation of the real-time and time-sharing subsystems is not restricted to the use of the CPU but enforced as well for other resources , namely main memory and caches. This paper details the changes needed for the original Linux to decouple it from real-time processes and analyzes the performance of the resulting system.
