An interesting anecdote from this month’s Linux Plumbers Conference in Tokyo is that Meta (Facebook) is using the Linux scheduler originally designed for the needs of Valve’s Steam Deck… On Meta Servers. Meta has found that the scheduler can actually adapt and work very well on the hyperscaler’s large servers.
SCX-LAVD as the Latency-criticality Aware Virtual Deadline scheduler has worked out very well for the needs of Valve’s Steam Deck with similar or better performance than EEVDF. SCX-LAVD has been worked on by Linux consulting firm Igalia under contract for Valve. SCX-LAVD has also seen varying use by the CachyOS Handheld Edition, Bazzite, and other Linux gaming software initiatives.
Really interesting. Perhaps we can try running it on normal PCs too to see what it does.
Oh, and on RISC V stuff.
