Embedded Linux BOF
summary
Group discussion catalogs concrete wins and pain points: prioritized boot time, system size, testing and build systems; practical tactics include U-Boot HTTP boot, uread-ahead, XIP where used, aggressive modular drivers with deferred probes and device-links, runtime-PM and offloading firmware to reduce an eight‑second camera startup, and using tracing/boot‑chart/logic probes to measure gains. The room notes a rapid shift to 64‑bit, 64 MB as a realistic minimum, Yocto LTS/resource gaps, the elinux wiki funding need (~$6k/yr), and a clear demand for more maintainers and upstream investment.
