Summary: Towards Unit Testing Real­Time Schedulers in LITMUS RT

Abstract
The problem of unit testing multiprocessor real­time
schedulers in operating systems such as LITMUS RT is
discussed. A tool intended to aid debugging by identi­
fying deviations from an intended scheduling policy and
performance regressions is proposed. This paper gives
a specification for the tool and also discusses ongoing
work on a prototype implementation.
1 Introduction
The advent of multicore computing has led to renewed
interest in real­time scheduling algorithms for multipro­
cessor systems. In research on this topic, the greatest
emphasis has been on purely algorithmic issues. To im­
pact the development of real systems, such work must
be complemented by prototype development, so that
scheduler­related overheads can be measured and the
practicality of proposed scheduling algorithms assessed.
