octep_alloc_ioq_vectors(9)

✨ octep_alloc_ioq_vectors ✨

okay so bestie, welcome to the kernel API manual for octep_alloc_ioq_vectors(9) — yes the section number is part of the name, we stan a numbered queen 👑. Pull up a chair, this one's short and sweet but it's lowkey important, iykyk.

---

🌸 NAME 🌸

octep_alloc_ioq_vectors — literally just allocating the Tx/Rx Queue interrupt info. that's the whole vibe. 🎀

---

🦋 SYNOPSIS 🦋

int octep_alloc_ioq_vectors (struct octep_device *oct );

like, one function, one argument, we love a minimal synopsis ✨

---

💅 ARGUMENTS 💅

• oct — the Octeon device private data structure. that's the one and only thing you hand it 🫶

---

🔥 DESCRIPTION 🔥

So what this does is it allocates the resources needed to hold the per Tx/Rx queue interrupt info. Think of it as setting up the little info packets each queue's interrupt is gonna carry around 💖

And what's in that info? It's the stuff that gets passed to the interrupt handler, and from there napi poll gets scheduled. It also gives you quick access to the private data of the Tx/Rx queue that corresponds to whichever interrupt is currently being handled — so like, no digging, no searching, just instant grab-and-go. main character energy honestly 🌟

---

⭐ RETURN ⭐

• 0 — slayed it. resources for all the queue interrupts got allocated successfully 🎉
• -1 — oop, failed to allocate any resource 😭 not a vibe.

ngl reading all forty-two of those in a row is a lot, but bestie they're all right there in the manual, so go off 💀

and that's the page!! mwah 💋 this manual page came from source ./drivers/net/ethernet/marvell... and it's dated October 2026 — go forth and allocate those vectors, periodt 💜🦋🌸
