Fair and Starvation-Free Spinlock for Real-Time AUTOSAR Systems

Activity: Talk or presentation › Talk at conference or symposium › Science to science

Description

We present in this paper, a fair and starvation-free spinlock protocol for partitioned fixed priority (P-FP) preemptive multi-core real-time operating systems (mRTOS). We discuss some strongly related works in this regard and highlight the drawbacks with respect to the AUTOSAR standards. We then proceed to define a system model and develop a mathematical framework to calculate an upper bound on the blocking time a task incurs under our protocol. We also discuss how our protocol was implemented in a state-of-the-art AUTOSAR-compliant mRTOS. Finally, through experimental evaluation, we show that our protocol performs better than the existing spinlock protocol of the mRTOS.
