💖 octeon_setup_interrupt(9) 💖

okay so this is a page from the Kernel API Manual, section 9 — yes bestie, the (9) is right there in the name, we love a consistent queen ✨

🎀 NAME 🎀

octeon_setup_interrupt — the girl whose whole job is setup interrupt for octeon device 💅

---

🌸 SYNOPSIS 🌸

int octeon_setup_interrupt (struct octeon_device *oct , u32 num_ioqs );

like, that's the whole signature. she's compact. she's iconic. she returns an int and takes exactly two things, no more no less 🫶

---

🦋 ARGUMENTS 🦋

• oct — the octeon device in question. your main character struct, a struct octeon_device * 🎀
• num_ioqs — number of queues, and it's a u32. count those queues, bestie 🔥

---

⭐ DESCRIPTION ⭐

So what does she actually do? She enables interrupt in the Octeon device as given in the PCI interrupt mask ✨

that's it. that's the vibe. no cap, she's not out here doing twelve things — she's doing the one thing, in the Octeon device, using the PCI interrupt mask as the source of truth 💜

ngl this is the kind of function that's lowkey holding the whole thing together. respect the process 🙈
