💅 cqm_setup_limbo_handler(9) — the Kernel API Manual, but make it cute

Okay so bestie, welcome to the Kernel API Manual ✨ and specifically to this little function that is literally about scheduling the limbo handler to run for a domain. Yes, "limbo handler" — iconic name, no notes 🎀

🌸 NAME 🌸

cqm_setup_limbo_handler — schedule the limbo handler to run for this domain, periodt 💅

---

✨ SYNOPSIS ✨

void cqm_setup_limbo_handler (struct rdt_l3_mon_domain *dom , unsigned
long delay_ms , int exclude_cpu );

That's the whole vibe check right there 🦋 — void return, three args, she's clean, she's simple, she's giving efficiency 👑

🫶 ARGUMENTS 🫶

• dom — the domain the limbo handler should run for 🏠 like, this is her domain and she's running it.
• delay_ms — how far in the future the handler should run ⏰ yes bestie, it's a time thing, plan accordingly.
• exclude_cpu — which CPU the handler should not run on 🙈, or RESCTRL_PICK_ANY_CPU if you want to just pick any CPU and let the universe decide 🌈.
