💅 init_apic_mappings(9) — the Kernel API Manual, bestie ✨

okay so real quick, this page lives in the Kernel API Manual, and it's about one tiny little function that literally just... initializes APIC mappings. that's the whole vibe. no cap, that's the entire description. 🎀

🌸 NAME 🌸

init_apic_mappings — initialize APIC mappings ✨

like, that's it. that's the mission statement. short, sweet, iconic.

---

🦋 SYNOPSIS 🦋

void init_apic_mappings (void );

look at her. no params, no drama, just vibes and a void. 💜

---

🧚 ARGUMENTS 🧚

• void — no arguments. none. zero. nada. she takes nothing and she gives everything, periodt. 🙈

---

👑 SEE ALSO 👑

okay so if you're obsessed with this one (and why wouldn't you be), the kernel file that keeps her is ./arch/x86/kernel/apic/apic.c — that's the main character address, iykyk. 🏠✨

and here's the whole friend group, all hanging out in section 9:

• lapic_get_maxlvt(9)
• clear_local_APIC(9)
• apic_soft_disable(9)
• disable_local_APIC(9)
• sync_Arb_IDs(9)
• setup_local_APIC(9)
• spurious_interrupt(9)
• connect_bsp_APIC(9)
• disconnect_bsp_APIC(9)
• apic_bsp_setup(9)

ngl that's a stacked lineup. go read them all, bestie, they're all in ./arch/x86/kernel/apic and they all ate. 🔥

fr fr this page is short but that's not a flaw, it's a lewk. don't go assuming this function does extra stuff the page doesn't say — if it's not written down here, it's not our business. 💀

and that's the whole page, bestie! 🫶 coming at you from ./arch/x86/kernel/apic, dated October 2026 — mwah, slay, bye! 💖🌈⭐
