ice_vsi_map_...s_to_vectors(9)

✨ NAME ✨

Okay bestie, welcome to the Kernel API Manual — today we're deep-diving ice_vsi_map_rings_to_vectors(9), which is literally the function that maps VSI rings to interrupt vectors. No cap, that's the whole name. 🎀

---

🔥 SYNOPSIS 🔥

void ice_vsi_map_rings_to_vectors (struct ice_vsi *vsi );

That's the whole signature, periodt. 💅

---

🎀 ARGUMENTS 🎀

• vsi — the VSI that's being configured. Like, this is the actual thing we're setting up, bestie. 🦋

---

💖 DESCRIPTION 💖

So what's the tea? This function maps descriptor rings to the queue-specific vectors that were allotted through the MSI-X enabling code. That's the main character energy right there. 👑

And when you're on a constrained vector budget? It maps Tx and Rx rings to the vector as "efficiently" as possible. Fr fr, it's giving resourceful. 🌸
