Meta Implements Linux Scheduler from Valve’s Steam Deck

At the Linux Plumbers Conference in Tokyo, it was revealed that Meta (formerly Facebook) is utilizing the Linux scheduler initially designed for Valve’s Steam Deck on its servers. The presentation titled “How do we make a Steam Deck scheduler work on large servers” discussed the adoption of SCX_LAVD as the default fleet scheduler, which performs well across various hardware configurations. This scheduler, built on sched_ext, enhances load balancing and adapts effectively to Meta’s large server environments. For further insights, the presentation and slide deck are available for review.
