irq_domain_...irq_and_chip(9)

💅 irq_domain_...irq_and_chip(9) — Kernel API Manual 💅

okay so bestie, welcome to the kernel API manual, specifically the page for irq_domain_set_hwirq_and_chip. yes the title got truncated to irq_domain_...irq_and_chip(9) — that's just the man page being dramatic about long function names, no cap. sit down, hydrate, let's get into it 🫶

---

✨ NAME ✨

irq_domain_set_hwirq_and_chip — sets the hwirq and irqchip of @virq over at @domain. literally what it says on the tin, she's an icon, she's straightforward 💖

---

🌸 SYNOPSIS 🌸

int irq_domain_set_hwirq_and_chip (struct irq_domain *domain , unsigned
int virq , irq_hw_number_t hwirq , const struct irq_chip *chip , void
*chip_data );

five args, one int back. she ate and left no crumbs 🔥

---

🎀 ARGUMENTS 🎀

• domain — the interrupt domain we're matching up. the venue for this whole situation 💒
• virq — the IRQ number. the virtual one, the vibe, the main character 😌
• hwirq — the hwirq number. the hardware-side bestie, the real one behind the scenes 🔧
• chip — the associated interrupt chip. the const struct irq_chip *, iconic, untouchable, don't @ her 👑
• chip_data — the associated chip data. a void *, so she contains multitudes, truly mysterious energy 🦋

ngl that's the entire page. no hidden lore, no sketchy caveats, just five arguments and a whole lot of friends in SEE ALSO. slay 💅

and that's a wrap bestie!! this page lives in ./kernel/irq, it's from the Kernel API Manual, dated October 2026 — so like, future-coded of her honestly 🌈⭐ go forth and map those interrupts, periodt 🧚‍♀️💜
