    I hate meta as much as the next guy, but according to this they are the #3 organization in terms of kernel contributions, behind only Intel and Red Hat...

    I hate Facebook as much as the next guy, but they did create React, as well as some other contributions.

    Really interesting. Perhaps we can try running it on normal PCs too to see what it does.
    Oh, and on RISC V stuff.

    Need to research what a scheduler means but all can think of is something like cron

    In my experience, a Scheduler is something that schedules time on the CPU for processes (threads).

    So 10 processes (threads) say "I need to do something":
    2 of those threads are "ready to continue" because they were previously waiting on some Disk IO (and responsibly released thread control while data was fetched).
    1 of the threads says "this is critical for GPU operations".
    1 of those threads self declares it is elevated priority.

    The scheduler decides which of those threads actually gets time on an available CPU core to be processed.

    The presentation at LPC 2025 by Meta engineers was in fact titled "How do we make a Steam Deck scheduler work on large servers." At Meta they have explored SCX_LAVD as a "default" fleet scheduler for their servers that works for a range of hardware and use-cases for where they don't need any specialized scheduler.

    🤣
