[$] Lessons from creating a gaming-oriented scheduler

At the 2025 Linux Plumbers
Conference (LPC), held in Tokyo in mid-December, Changwoo Min led a session on what
he has learned while developing the
"latency-criticality
aware virtual deadline" (LAVD) scheduler, which is aimed at gaming
workloads. The session was part of the Gaming
on Linux microconference, which is a new entrant into LPC; organizers
hope to see it return next year in
Prague and, presumably, beyond. LAVD uses the extensible scheduler class (sched_ext) and has
the primary goal of minimizing stuttering
in games;
it is implemented in a combination of BPF and Rust.
