This session introduces a unified boot time measurement framework that overcomes these limitations. Inspired by U-Boot’s bootstage mechanism, it leverages hardware timers to generate synchronized timestamps across heterogeneous subsystems. Instead of relying on fragmented logs, the framework writes boot markers to a reserved DDR memory region, enabling a Linux utility to extract and analyze the complete boot timeline via the devmem interface. This approach ensures end-to-end visibility, enabling developers to pinpoint inefficiencies, optimize boot sequences, and improve system responsiveness.

With the increasing complexity of embedded devices—ranging from IoT and industrial automation to automotive and networking—achieving fast and predictable boot times is more important than ever. This talk provides a vendor-agnostic, software-based approach to measuring and optimizing boot performance, benefiting developers working on custom Linux BSPs, embedded RTOS systems, and real-time applications.
