ap_aqic(9)

✨ ap_aqic — like, the Kernel API Manual page for it ✨

Okay bestie, so this is a page from the Kernel API Manual (yes, that's the manual's name, we're not copying the literal header line, we're being cute about it) and it's about ap_aqic — which, as the NAME says, is all about control interruption for a specific AP. 💅

---

🎀 NAME 🎀

ap_aqic — control interruption for a specific AP. That's it, that's the whole vibe. One specific AP. Not all of them. A specific one. 👑

---

🌸 SYNOPSIS 🌸

struct ap_queue_status ap_aqic (ap_qid_t qid , union ap_qirq_ctrl
qirqctrl , phys_addr_t pa_ind );

Look at that signature, it's giving "three args, zero chill." 🦋

---

✨ ARGUMENTS ✨

• qid — the AP queue number. Like the AP's little address label, y'know? 🏷️
• qirqctrl — a struct ap_qirq_ctrl (and btw it's a 64 bit value, so she's thicc). 💜
• pa_ind — the physical address of the notification indicator byte. Physically addressed, extremely iconic. 📍

---

💖 DESCRIPTION 💖

Returns AP queue status. That's the whole description, no cap. Short and slay. 💀✨

Bestie heads up: this page is from the ./arch/s390/include/asm corner of the world, dated October 2026 — so when you come back to it later, that's the version you're reading. Don't @ me. 😭💖

And that's the whole page! Mwah, go forth and interrupt responsibly. 🎀👑⭐
