Kernel-level ARINC 653 partitioning for Linux
Sanghyun Han, Hyun‐Wook Jin · 2012
The Integrated Modular Avionics (IMA) architecture has been suggested for the next-generation avionics systems. ARINC 653 is the standard for application programming interfaces (APIs) of avionics software for IMA architecture. There are several researches on design and implementation of ARINC 653 but legacy operating systems have not been considered much for a base operating system of ARINC 653. Though the legacy operating systems may not be initially developed for avionics systems, some of them including Linux recently show high potential of providing software platform for avionics systems. In this paper, we suggest a kernel-level design to support partitioning and hierarchical real-time scheduling of ARINC 653 for Linux. We believe that our suggestion can provide a very valuable reference for extending an existing operating system for ARINC 653 especially due to the complexity of the Linux kernel. We show that the overhead and jitter of the proposed design is significantly low compared with a user-level design.
