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

okay so first things first: the page is literally called msix_initialize, and it lives in the Kernel API Manual. That's the whole vibe. It's a kernel function. It's giving low-level. It's giving "I talk to hardware and you don't." 🎀

✨ NAME ✨

msix_initialize — Calculate, request and configure MSIx IRQs

Three jobs, one function, no cap. It does the calculating, it does the requesting, and it does the configuring — all of it, MSIx IRQs, together, iconic behavior honestly. 👑

---

🌸 SYNOPSIS 🌸

int msix_initialize (struct hfi1_devdata *dd );

That's it. That's the whole call. One argument, returns an int, done. Simple queen energy. ✨

---

🦋 ARGUMENTS 🦋

• dd — a valid hfi1 devdata. Like, valid valid. It's a struct hfi1_devdata * and it's the one and only thing you're handing over, so bestie please make sure it's the real deal before you pass it in. 🙈
