A Solution to High Latencies Caused by I/O - BFQ I/O Scheduler

Explore a comprehensive solution to high latencies caused by I/O in this 41-minute conference talk by Paolo Valente from Linaro. Delve into the BFQ I/O scheduler's integration into the Linux kernel, examining its benefits for embedded systems, including improved responsiveness, low latency for time-sensitive applications, and enhanced fairness. Compare these advancements with current latency and unfairness issues in Linux-based embedded systems through demos and real hardware data. Learn about the potential impact on major embedded OSes like Android and gain insights from Valente's expertise in scheduling algorithms for storage devices, transmission links, and CPUs. Discover the speaker's contributions to Linux and FreeBSD, including the QFQ packet scheduler and its faster variant, QFQ+. The talk covers introduction, agenda, schedulers, Android, fast network, Linux, Debian, analysis, results, and concludes with a Q&A session.
