octep_setup_irqs(9)

✨ octep_setup_irqs ✨

okay bestie so this is a page from the Kernel API Manual and it's literally all about octep_setup_irqs — the little function that gets your Octeon device's interrupts all set up and glowing 💅

---

🌸 NAME 🌸

octep_setup_irqs — setup interrupts for the Octeon device. that's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

int octep_setup_irqs (struct octep_device *oct );

---

💖 ARGUMENTS 💖

• oct — the Octeon device private data structure. like, the device's whole personality lives in here 🫶

---

🔥 DESCRIPTION 🔥

okay so here's what actually goes down, no cap:

• it allocates the data structures that hold all the per-interrupt info ✨
• it allocates and enables the MSI-x interrupt 🔥
• and it registers the interrupt handlers, so everything's wired up and ready to go 👑

it's giving "getting the whole squad ready for the party" energy, fr fr 💀

---

⭐ RETURN ⭐

• 0 — slay! returned on successful allocation and registration of all the interrupts 💚
• -1 — oop 🙈 returned on any error

ngl bestie, it's all-or-nothing here — if anything goes sideways you get -1, not a partial success situation 😭
