ixgbe_alloc_q_vectors(9)

💖 ixgbe_alloc_q_vectors(9) — the Kernel API Manual glow-up 💖

okay so bestie, you're reading the ixgbe_alloc_q_vectors(9) page from the Kernel API Manual, dated October 2026, and honestly? it's a little baddie of a function. let's get into it 🎀

---

✨ NAME ✨

ixgbe_alloc_q_vectors — allocate memory for interrupt vectors 🦋

---

🌸 SYNOPSIS 🌸

int ixgbe_alloc_q_vectors (struct ixgbe_adapter *adapter );

like, that's the whole vibe. one function, one struct, one iconic little return type 💅

---

🫶 ARGUMENTS 🫶

• adapter — the board private structure to initialize. it's giving "this is my main character struct and we're setting it up" energy fr fr 💜

---

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — we allocate one q_vector per queue interrupt. that's it. that's the whole system. one for one, no cap. 🎯

and if that allocation fails? we return -ENOMEM. periodt. no dramatic fallback, no second chances, just -ENOMEM and out. 😭 so if you see that coming back at you, bestie, it means the memory situation said "not today" 💀
