topology_hotplug_apic(9)

💅 NAME 💅

Okay bestie, welcome to the Kernel API Manual page for topology_hotplug_apic(9) — yes, that's the whole title, we're doing this.

topology_hotplug_apic — it handles a physical hotplugged APIC after boot. That's the vibe. Iconic little boot-time cleanup behavior, no cap. 💖

✨ SYNOPSIS ✨

int topology_hotplug_apic (u32 apic_id , u32 acpi_id );

Literally the function signature, copied exactly, because we do not play with code. 🫶

🎀 ARGUMENTS 🎀

• apic_id — the APIC ID to set up. That's it, that's the assignment. 💅
• acpi_id — the ACPI ID associated to the APIC. Matching bestie energy. 🦋
