Open Source Summit Japan & Automotive Linux Summit 2020

Boot-time tracing is one of the latest Linux kernel tracing proposal, which allows us to trace kernel booting with full tracing features, like per-event filters and triggers, histograms, instances, dynamic-events etc. Along with the boot-time tracing, we also introduce the Extra Boot Configuration (bootconfig) to expand the kernel command-line interface so that user can specify complex boot-time settings with structured-key value configuration file. This talk will show you what the boot-time tracing and the bootconfig provide, the advantages and how you can use it for your boot-time features.
