💅 irq_domain_alloc_generic_chips(9) — like, the whole glow-up

okay bestie, welcome to the Kernel API Manual 🎀 this one's a little corner of the kernel that hands out generic chips to an irq domain, and honestly? it's giving allocator realness. no cap.

---

✨ NAME ✨

irq_domain_alloc_generic_chips — Allocate generic chips for an irq domain 🧚

like. that's the whole job. it allocates. the chips are generic. the domain is irq. iconic behaviour tbh.

---

🌸 SYNOPSIS 🌸

int irq_domain_alloc_generic_chips (struct irq_domain *d , const struct irq_domain_chip_generic_info *info );

two args, returns an int, lowkey straightforward 💖

---

🦋 ARGUMENTS 🦋

• d — the irq domain for which to allocate chips 👑 this is the main character, the domain getting all the chip attention
• info — Generic chip information 🍓 literally the info about the generic chips. that's it. that's the vibe

---

⭐ RETURN ⭐

• 0 on success 🎉 slay, it worked
• negative error code on failure 😭 not slay, something went wrong, and it tells you with a negative number
