amdgpu_irqdomain_map(9)

💅 amdgpu_irqdomain_map 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a lil function from the DRM/amdgpu corner of the kernel, and it's literally just here to make virtual and hardware IRQ numbers be friends 🫶

---

🎀 NAME 🎀

amdgpu_irqdomain_map — creates the mapping between virtual and hardware IRQ numbers, no cap 💖

---

✨ SYNOPSIS ✨

int amdgpu_irqdomain_map (struct irq_domain *d , unsigned int irq ,
       irq_hw_number_t hwirq );

that's the whole vibe right there 👑

---

🌸 ARGUMENTS 🌸

• d — the amdgpu IRQ domain pointer — and yeah, plot twist, it's unused 🙈 (she's just here for moral support)
• irq — the virtual IRQ number 🦋
• hwirq — the hardware IRQ number ⭐

---

💜 DESCRIPTION 💜

So the current implementation? It assigns a simple interrupt handler to the virtual IRQ you passed in. That's it, that's the whole personality 💅 short, sweet, iconic.

---

🔥 RETURN 🔥

• 0 on success — slay 🎉
• an error code otherwise — not slay, but like, informative 😭
