💅 scx_bpf_events(9) — the Kernel API Manual glow-up ✨

okay so bestie, this is the scx_bpf_events page from the Kernel API Manual, section 9, and it is literally about reading event counters. no cap, it's giving kernel-core main character energy 👑

🌸 NAME 🌸

scx_bpf_events — read the event counters of the calling scheduler 🫶

✨ SYNOPSIS ✨

__bpf_kfunc void scx_bpf_events (struct scx_event_stats *events , size_t events__sz , const struct bpf_prog_aux *aux );

🎀 ARGUMENTS 🎀

  • events — the output buffer, coming straight from a BPF program 💖
  • events__sz — the length of events; bestie, it must end in '__sz' for the verifier, that's the vibe check 🔥
  • aux — the implicit BPF argument used to access bpf_prog_aux, hidden from BPF progs 🙈

🦋 DESCRIPTION 🦋

So this reads the event counters of the scheduler associated with the calling program. That's the whole slay 💅. And if no scheduler can be resolved? events is zeroed, periodt.

🌈 SEE ALSO 🌈

Kernel file ./kernel/sched/ext/ext.c — and the whole friend group is here, in order, no gatekeeping:

mwah 💋 this lil rewrite came from source/version ./kernel/sched/ext, dated October 2026, and it's still scx_bpf_events(9) at heart. bye bestie 🎀✨
