GNU/Linux is one of the most scalable OS and one wonders why it can’t power contemporary automotive Instrument Clusters. GNU/Linux is already powering In-Vehicle Infotainment Systems. The same HMI & user experience is possible on Instrument Cluster. Additionally, Instrument Cluster needs more real time responsiveness and is a critical component of any vehicle. Recent GNU/Linux kernel has an in-built Real-time personality. It can provide Instrument Clusters with a progressive platform spanning multiple feature-sets while significantly reducing Development and Test Cycles. From Hybrid to reconfigurable & futuristic Instrument Clusters, GNU/Linux can power all. This paper discusses suitability, common concerns, challenges & adoption strategies of GNU/Linux for Instrument Clusters. Audience: Product & Engineering managers looking forward to GNU/Linux as potential OS Solution
