ps3_io_irq_setup(9)

🎀 NAME 🎀

okay so bestie, welcome to the Kernel API Manual entry for ps3_io_irq_setup(9) 💅

ps3_io_irq_setup — Setup a system bus io irq. ✨ that's literally the whole vibe. it sets up an io irq. on the system bus. no cap.

---

🦋 SYNOPSIS 🦋

int ps3_io_irq_setup (enum ps3_cpu_binding cpu , unsigned int
interrupt_id , unsigned int *virq );

copy it exactly like that, bestie, spacing and all, don't be out here improvising 🙈

---

🌸 ARGUMENTS 🌸

• cpu — an enum ps3_cpu_binding telling us which cpu the interrupt should be serviced on. like, which core is on duty for this one 🫶
• interrupt_id — the device interrupt id, read from the system repository. that's where you go get it, fr fr.
• virq — the assigned Linux virq. it's a unsigned int *, so yes, pointer energy 👑

---

✨ DESCRIPTION ✨

so an io irq represents a non-virtualized device interrupt. that's the whole definition, iconic, no notes 💖

and interrupt_id corresponds to the interrupt number of the interrupt controller. that's it, that's the mapping — don't overthink it, bestie 🧚

ok that's the page!! go set up some irqs responsibly, ily 💜

mwah 💋 — this came from ./arch/powerpc/platforms/ps3, dated October 2026, and it's ps3_io_irq_setup(9) in the Kernel API Manual. that's a wrap, periodt 🎀✨
