Presentation

Chasing milliseconds: how we optimized in-vehicle OS boot time

The presentation will take you on a technical journey through some of the challenges of adapting a general-purpose Linux OS to an embedded automotive use case with strict regulatory and safety requirements. Extra seconds of boot time are hardly noticeable or impactful for servers with hundreds of days of uptime, but for a platform rebooted many times in a day and that must provide user interaction in seconds from power on for safety reasons, suddenly every CPU cycle is under the microscope.

The audience will learn:

  • Firmware loading, kernel optimization, initrd minimization, I/O device acceleration
  • Deploying critical applications to the earliest possible CPU cycle
  • Differences between optimizing x86_64 and aarch64 environments
  • Collecting and analyzing performance data at scale
  • Tools and methods used by expert engineers
