SCHED_DEADLINE: New Features and Development in Linux Kernel Scheduling

Explore the latest developments in Linux kernel's SCHED_DEADLINE scheduling policy in this informative conference talk. Dive deep into new features under development, including CPU capacity and clock frequency scaling, bandwidth reclaiming, coupling with clock frequency selection, and cgroups support. Learn about open problems and potential future enhancements for this critical scheduling mechanism. Gain insights from Juri Lelli, one of the original authors of SCHED_DEADLINE, as he discusses the collaborative efforts between ARM, Luca Abeni, and Scuola Superiore Sant'Anna of Pisa. Understand the evolution of deadline scheduling for processes since its introduction in Linux kernel version 3.14 and discover how these advancements impact energy-aware scheduling and power management.
