Explore a systematic approach to automotive safety certification for open source software in this 30-minute conference talk by Paul Sherwood. Delve into the journey that began in 2016 with autonomous vehicles and Linux-based infotainment systems, addressing the scalability of safety in free and open-source software (FOSS). Examine the default paths through ISO 26262, the concept of "proven in use," and the development of a systematic method reviewed with Exida. Analyze safety considerations for Linux as a host for safety applications, including control structure, shared compositor access hazards, and loss scenarios for Automotive Grade Linux (AGL). Discover mitigation strategies and updated designs resulting from thorough safety analysis.
A Path to Automotive Safety Certification for Open Source
Overview
Syllabus
Intro
Where our path started: 2016 • Autonomous vehicles: Al workloads, preferably Linux • Is our infotainment work safety relevant? • Tieri: how do we scale safety - is there anything in FOSS? • OEM: "Can Linux be safety-certified?"
The default paths through ISO 26262 • Proven in use
Our first step... • Trustable software: input
Recent steps... • We developed a systematic method, discussed with customers, reviewed with Exida
Current step: Linux host for safety application
Safety analysis: Control structure
Example hazard: Shared compositor access Initial design
Example hazard: Loss scenarios for AGL
Mitigation: Nested compositor Updated design after analysis
