Booting Automotive ECUs Really Fast with Modern Security Features

Explore the challenges and solutions for rapidly booting automotive Electronic Control Units (ECUs) while maintaining modern security features in this conference talk by Brendan Le Foll from BMW Car IT GmbH. Discover the unique requirements of using Linux in the automotive industry, focusing on boot time and performance indicators. Learn about the implementation of Yocto/Poky with Android-derived features and GENIVI/COVESA components across various automotive control units. Delve into strategies for meeting demanding Key Performance Indicators (KPIs) such as the 2-second rear view camera activation, while enabling secure boot, dm-verity, IPsec, and SELinux. Gain insights into hardware characteristics crucial for fast boot times, BMW's proposed patches to systemd for an 'early' boot target, and the potential for cross-industry collaboration on boot time optimization.
