A RISC-V Open-Source Platform for Reliability Evaluation in Safety-Critical Operating Systems

The growing adoption of RISC-V architectures in safety-critical applications has increased the demand for robust and reliable computing platforms. In operating system-based architectures, radiation-induced faults can alter system memory or register contents, leading to unintended behavior or, in the worst case, system halts. To mitigate such risks, the dependability of operating systems has to be investigated and enhanced, reducing the probability of system failures in the presence of errors. This work proposes a reliability-oriented open-source platform based on the porting of the MIT PDOS xv6-riscv education Operating System for the VisionFive 2 board.
