The Power Management and Scheduling in the Linux Kernel Summit, which still goes by the historical acronym OSPM, was held in Cambridge, UK, in mid-April. As has become traditional, the presenters at that event have since written summaries of their sessions, and this work has kindly been made available to LWN for publication. The second day's sessions covered a wide range of topics, including device frequency scaling, using time-slice duration for CPU selection, scheduling domains on multi-cluster Arm systems, the LAVD scheduler, and more.
