Tracing Resource-constrained Embedded Systems Using eBPF

Explore the challenges and solutions for tracing resource-constrained embedded systems using eBPF in this informative conference talk. Begin with a brief introduction to eBPF's powerful tracing capabilities and the mainstream approach using the eBPF Compiler Collection. Delve into the specific hurdles faced when implementing these tools on embedded devices, including portability issues, kernel headers and build problems, and size constraints. Examine four separate projects aimed at bringing eBPF functionality to embedded systems, comparing their approaches, trade-offs, and current stages of development. Gain insights into areas requiring further effort and research in this emerging field of embedded system tracing.
