pm8001_inte...handler_msix(9)

💖 pm8001_interrupt_handler_msix — the Kernel API Manual, bestie edition 💖

Okay so this is the Kernel API Manual page for pm8001_interrupt_handler_msix, and honestly? It's kind of the main character of the MSIX world. Let's get into it. 🦋

---

✨ NAME ✨

pm8001_interrupt_handler_msix — the main MSIX interrupt handler. No cap, it grabs the vector number and then either calls the equivalent bottom half or just services the thing directly. That's the whole vibe check. 💅

---

🎀 SYNOPSIS 🎀

irqreturn_t pm8001_interrupt_handler_msix (int irq , void *opaque );

Bestie, look at that signature. Clean. Iconic. Exactly as written. ✨

---

🌸 ARGUMENTS 🌸

• irq — the interrupt number. That's it, that's the whole thing. It's giving "just a number" but make it essential. 🔥
• opaque — the outbound queue/vector that got passed in. The host structure gets retrieved from this exact same thing, so like… don't lose it? 🙈
