irq_get_domain_generic_chip(9)

💅 irq_get_domain_generic_chip(9) 💅

okay so like, hi bestie 🌸 welcome to the Kernel API Manual, and today's main character is irq_get_domain_generic_chip — no cap, she's a little function with a big name and a very specific job 💖

---

✨ NAME ✨

irq_get_domain_generic_chip — get a pointer to the generic chip of a hw_irq 🎀

like literally, you hand her a domain and a hardware interrupt number, and she hands you back a pointer to that interrupt's generic chip. it's giving "personal assistant who knows where everything is" energy fr fr ✨

---

🦋 SYNOPSIS 🦋

struct irq_chip_generic * irq_get_domain_generic_chip (struct irq_domain
*d , unsigned int hw_irq );

that's her whole signature, exactly as written, don't come for me about the line break 💀

---

🌈 ARGUMENTS 🌈

• d — the irq domain pointer 💫 lowkey the map you're searching in
• hw_irq — the hardware interrupt number 🔥 the exact hw irq you're asking about

two args, both doing exactly what they say on the tin. iconic behavior honestly 👑

---

💜 SEE ALSO 💜

first of all, she lives in the kernel file ./kernel/irq/generic-chip.c — that's her address, bestie 🏠

like yes that's seventeen of them and yes i listed every single one, we don't do "etc." around here 💅✨

🫶 quick reminder bestie: the synopsis is written exactly as the original has it — same types, same pointers, same semicolons — so don't go "cleaning it up" on me, mwah 😭

and that's the page! 🌟 she's from ./kernel/irq, dated October 2026, and yeah — the whole thing is still filed under irq_get_domain_generic_chip(9) at the bottom, periodt 💖🎀🦋
