The purpose of this paper is to validate the real-time system in the Linux-RTAI/LXRT (Real Time Application Interface/Linux Real-time) environment, in the presence of hardware and software faults. Due to the simplicity of creating and injecting faults, the method of Software Implemented Fault Injection (SWIFI) is selected. With this mode of fault injection, a tested system can emulate real conditions, in which it is required to function. The Linux operating system was selected due to open source code and ease of manipulation of various parts. Verifications of some tests performed earlier by different authors, on various hardware and software platforms, have been made. The Linux operating system has been modified with an RTAI/LXRT patch in order to gain real-time system functionality. Subsequently, modification of the respective parts of the operating system was made to enable the injection of faults. After the injection of faults, several testing frames were selected to verify and validate the real-time system. Encouraging results have been obtained towards verifying the hard real-time capabilities of Linux RTAI/LXRT System. [ABSTRACT FROM AUTHOR] |
