wx_acquire_msix_vectors(9)

💅 wx_acquire_msix_vectors — like, the whole entire manual, bestie

okay so real talk: this is the wx_acquire_msix_vectors(9) page from the Kernel API Manual, and it's short but it matters, so let's get into it 🫶

---

✨ NAME ✨

wx_acquire_msix_vectors — acquire MSI-X vectors 🔥

(yes that's it. yes it's iconic. moving on.)

---

🌸 SYNOPSIS 🌸

int wx_acquire_msix_vectors (struct wx *wx );

that's the whole signature, no cap. returns an int, takes one pointer, done 💅

---

🎀 ARGUMENTS 🎀

• wx — the board private structure 💖 (like, the driver's own lil personal data blob for this board, iykyk)

---

🦋 DESCRIPTION 🦋

so what does it do? it attempts to acquire a suitable range of MSI-X vector interrupts ⚡

and if it can't — for any reason — it will return a negative error code. that's the vibe check failing, bestie 😭 negative number = nope, no vectors for you.

fr fr: any failure mode, any reason, you get a negative error code back. plan for it 🙈
