airq_iv_create(9)

💅 airq_iv_create(9) — a Kernel API Manual moment

okay bestie, welcome to the airq_iv_create(9) page from the Kernel API Manual!! this is the s390 cio girlies' corner of the kernel and honestly it's giving underrated icon behavior ✨

---

🌸 NAME 🌸

airq_iv_create — create an interrupt vector 💖

---

🎀 SYNOPSIS 🎀

struct airq_iv * airq_iv_create (unsigned long bits , unsigned long flags , unsigned long *vec );

like, that's the whole vibe: you hand it bits, flags, and a vec, and it hands you back a struct airq_iv *. slay 🫶

---

✨ ARGUMENTS ✨

• bits — the number of bits in the interrupt vector. that's the size, bestie, the literal bit budget 💅
• flags — the allocation flags. yes it's plural, yes you pass them, no we don't elaborate here 🔥
• vec — a pointer to pinned guest memory, but only if AIRQ_IV_GUESTVEC is set. no AIRQ_IV_GUESTVEC, no guest memory pointer, iykyk 🌈

---

🦋 DESCRIPTION 🦋

Returns a pointer to an interrupt vector structure. that's it, that's the whole description — short, sweet, main character energy 👑

💜 SEE ALSO 💜

the kernel file lives at ./drivers/s390/cio/airq.c and honestly it's the source of truth, go read her 📖
