igc_alloc_q_vectors(9)

📦 version 7.3.1, in nixpkgs unstable

💅 igc_alloc_q_vectors(9) 💅

okay so this is a page from the Kernel API Manual — yes that Kernel API Manual, the one your kernel-dev bestie keeps open in a tab — and it's all about igc_alloc_q_vectors. buckle up, it's short but it's mighty. 🎀

✨ NAME ✨

igc_alloc_q_vectors — the girl whose whole job is literally allocating memory for interrupt vectors 💖 no cap, that's it, that's the whole name.

🌸 SYNOPSIS 🌸

int igc_alloc_q_vectors (struct igc_adapter *adapter );

so she takes one thing and one thing only, and yes the spacing in the original is exactly like that. slay. 🫶

🦋 ARGUMENTS 🦋

  • adapter — the board private structure you're gonna initialize. that's it, that's her. don't overthink it, bestie. 💜

🧚 DESCRIPTION 🧚

okay so the whole vibe here: we allocate one q_vector per queue interrupt. one. per. queue. interrupt. the way that's so simple and yet so iconic 😭

and if that allocation fails? we return -ENOMEM. that's the whole drama. no fancy fallback, no backup plan, just -ENOMEM straight to your face. ngl, respectful. 💀

lowkey important: -ENOMEM means the memory situation did not slay. check your return value, bestie, always. ✨

👑 SEE ALSO 👑

first up, the literal file this lives in — bookmark it, it's giving main character energy:

Kernel file ./drivers/net/ethernet/intel/igc/igc_main.c

and now, the friend group 💅 (yes, all of them, i'm not skipping a single one, that would be so rude):

like?? the references alone are a whole roster 🌈 and yeah, igc_alloc_q_vector(9) (singular) and igc_alloc_q_vectors(9) (plural) are both there — don't mix them up, they are different queens. 👑

and that's the page, bestie!! fr fr short and sweet 🍓 sign-off time: this lil treasure lives under ./drivers/net/ethernet/intel/igc and the date stamped on it is October 2026 — so yeah, she's from the future, we stan a time-traveling manpage ⭐💖
