msix_request_irqs(9)

💅 msix_request_irqs(9) — from the Kernel API Manual, bestie

Okay so picture this: you're deep in the Kernel API Manual, section 9, and you've found the page for msix_request_irqs. Yes, we are that kind of girl. Come sit, I'll explain.

---

✨ NAME ✨

msix_request_irqs — the one that allocates all the MSIx IRQs. All of them. The whole squad. 🫶

---

🦋 SYNOPSIS 🦋

int msix_request_irqs (struct hfi1_devdata *dd );

That's it. That's the whole entrance exam. One function, one pointer, one int back. Lowkey iconic. ⭐

---

🎀 ARGUMENTS 🎀

• dd — a valid devdata structure. That's it. That's the requirement. It just has to be valid, no cap. ✨

---

💖 DESCRIPTION 💖

It's a helper function — a little bestie who does a job for you — and its whole job is to request the used MSIx IRQs. That's the vibe. It doesn't externalize the lore, it just grabs those IRQs so you don't have to. Main character energy but make it a subroutine. 👑

Heads up: dd needs to be a valid devdata structure. The manpage does not elaborate on what happens otherwise, and neither will I, because I refuse to make things up. 🙈
