scx_bpf_nr_node_ids(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is the scx_bpf_nr_node_ids page from the Kernel API Manual, and bestie… it’s literally a tiny little baddie of a kfunc 💅✨

🎀 NAME 🎀

  • scx_bpf_nr_node_ids — Return the number of possible node IDs 🫶

✨ SYNOPSIS ✨

__bpf_kfunc u32 scx_bpf_nr_node_ids (void );

🌸 ARGUMENTS 🌸

  • void — no arguments, bestie. not a single one. zero. nada. the void is voiding 🕳️💖

🦋 DESCRIPTION 🦋

okay so here’s the vibe: All valid node IDs in the system are smaller than the returned value. That’s the whole flex. no cap, that’s the entire description — valid node IDs stay lowkey under what this returns 🌈

👑 SEE ALSO 👑

Kernel file: ./kernel/sched/ext/ext.c — and the whole friend group is here, in original order, because we respect the lore 💜:
