vring_interrupt(9)

💅 vring_interrupt(9) — Kernel API Manual bestie era ✨

okay so bestie, welcome to the Kernel API Manual page for vring_interrupt(9) — manual name folded in near the top, as requested 🎀. This is a tiny page with big "notify the virtqueue" energy, and we're gonna keep every detail, no cap.

---

💖 NAME 💖

vring_interrupt — notify a virtqueue on an interrupt 💅

---

✨ SYNOPSIS ✨

literally the signature, exactly:

irqreturn_t vring_interrupt (int irq , void *_vq );

---

🎀 ARGUMENTS 🎀

• irq — the IRQ number (ignored) 🙈. yes, it's in the signature; yes, it's ignored. we love a parameter that knows its place.
• _vq — the struct virtqueue to notify 👑. this is the one doing the notification processing, iykyk.

---

🦋 DESCRIPTION 🦋

the whole vibe is: it calls the callback function of _vq to process the virtqueue notification ✨. that's it. that's the description. _vq is the struct virtqueue to notify, and the callback function gets called to process the virtqueue notification. no extra lore, no secret bonus steps — fr fr 💖.
