💅 octep_vf_setup_irqs(9) — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the octep_vf_setup_irqs(9) page from the Kernel API Manual 💖 this is a section-9 kernel function and she is lowkey the setup queen for the Octeon device's interrupts. buckle up 🎀

✨ NAME ✨

octep_vf_setup_irqs — setup interrupts for the Octeon device. that's it, that's the whole vibe 🫶

🌸 SYNOPSIS 🌸

int octep_vf_setup_irqs (struct octep_vf_device *oct );

like, she takes one pointer and returns an int. iconic behaviour tbh 👑

🦋 ARGUMENTS 🦋

  • oct — the Octeon device private data structure. this is the main character struct you're handing over, no cap 💅

💖 DESCRIPTION 💖

so here's the tea, fr fr — this function does the whole interrupt glow-up in three steps:

  • allocate data structures to hold per interrupt information,
  • allocate/enable MSI-x interrupt,
  • and register interrupt handlers.

that's the triple threat right there ✨ allocate the per-interrupt info holders, get those MSI-x interrupts allocated and enabled, then hook up the handlers. she's doing the most and honestly? slay 💜

⭐ RETURN ⭐

  • 0 — on successful allocation and registration of all interrupts 🎉 like, everything worked, we ate.
  • -1 — on any error 😭 any error at all, doesn't matter which one, you're getting -1. no in-between, periodt.

like, read them all, iykyk 🧚‍♀️

ngl bestie, -1 is the only failure code here — no fancy errno, just vibes and a -1. keep that in mind 💀

and that's a wrap, babe 🌸 this page is coming at you from ./drivers/net/ethernet/marvell... and she's stamped October 2026, filed under octep_vf_setup_irqs(9) — mwah, go set up those interrupts, you've got this 💅💖🎀
