scx_bpf_get_online_cpumask(9)

💖 scx_bpf_get_online_cpumask(9) 💖

okay so bestie, welcome to the Kernel API Manual — this page is literally scx_bpf_get_online_cpumask(9), and it’s a short one, so we can absolutely devour it. 💅✨

🌸 NAME 🌸

scx_bpf_get_online_cpumask — get a referenced kptr to cpu_online_mask 🫶

✨ SYNOPSIS ✨

the whole signature, copied exactly because we do not play with code, periodt:

__bpf_kfunc const struct cpumask * scx_bpf_get_online_cpumask (void );

🎀 ARGUMENTS 🎀

• void — no arguments. literally none, bestie. the vibe is “takes nothing” and that’s it. 🙈
