An evaluation of the POSIX trace standard implemented in RT-linux

Abstract

As real-time applications become more complex, the availability of event tracing mechanisms becomes more important in order to perform run-time monitoring. The recent approved standard POSIX 1003.Iq defines a common application interface for trace management. In this paper we present our experience with the implementation of a subset of the approved tracing standard that conforms to the POSIX Minimal Real-Time System Profile. The implementation has been done in the RT-Linux operating system, in order to obtain a real-time kernel with standard tracing services that conforms to the Minimal ProJile.
