iavf_reinit_...rrupt_scheme(9)

💖 iavf_reinit_interrupt_scheme(9) 💖

okay so bestie, this is a page straight out of the Kernel API Manual — like, the actual kernel docs — and it's about one little function that lives in the iavf driver. it's short, it's sweet, and yes we're gonna read it together. grab a lil snack 🍓

---

✨ NAME ✨

iavf_reinit_interrupt_scheme — the function that reallocates queues and vectors. that's the whole vibe. it tears the interrupt setup down and puts it back together, no cap. 🔁

---

🌸 SYNOPSIS 🌸

int iavf_reinit_interrupt_scheme (struct iavf_adapter *adapter , bool
       running );

look at her. returns an int, takes a pointer to a struct iavf_adapter plus a bool called running. that's it, that's the signature, copy it exactly bestie 💅

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure. it's the lil (okay, big) struct holding all this device's business. literally the main character of the driver 🎀
• running — this one's true if adapter->state == __IAVF_RUNNING. so like, it's the "hey are we actively running right now" flag. that's the check, verbatim, don't @ me.

---

👑 DESCRIPTION 👑

so what does she do? she returns 0 on success, negative on failure. that's the documented behavior, periodt. ✨

ngl, that's genuinely all the description there is. short king of a description. no extra lore, no secret tips — just the return contract, and we respect it 🙈

okay this is the part where the manpage just... goes off. the source file is ./drivers/net/ethernet/intel/iavf/iavf_main.c — that's home base 🏠 — and then there's a whole friend group of related kernel functions, all in section (9). every single one, in order, because we do not skip:
