💅 ps3_vuart_irq_handler(9) — Kernel API Manual, bestie edition ✨

Okay so this is a page from the Kernel API Manual about ps3_vuart_irq_handler, and it is literally the first stage interrupt handler 🎀. Yes, "first stage" — like she's the opening act and the main character energy comes later. Periodt.

✨ NAME ✨

ps3_vuart_irq_handler — first stage interrupt handler 🦋

---

🌸 SYNOPSIS 🌸

irqreturn_t ps3_vuart_irq_handler (int irq , void *_private );

---

🎀 ARGUMENTS 🎀

• irq — -- undescribed -- 🙈 bestie the docs really said "no thoughts, head empty" on this one
• _private — -- undescribed -- 😭 same vibe, also undescribed

---

💖 DESCRIPTION 💖

So what she does is: she loops, finding any interrupting port and its associated instance data 🔍✨. Then she passes control to the second stage port specific interrupt handler — like, "here you go queen, she's all yours" 🫶. And she keeps looping until all outstanding interrupts are serviced 🔥. No leftovers, no stragglers, no "oops I missed one." Iconic behaviour honestly.
