💅 ih_v6_1_irq_init(9) — Kernel API Manual ✨

okay so bestie, welcome to the Kernel API Manual page for ih_v6_1_irq_init(9) — it’s giving interrupt-ring main character energy and we’re gonna read it together 🫶

---

🎀 NAME 🎀

ih_v6_1_irq_init — init and enable the interrupt ring. periodt.

---

✨ SYNOPSIS ✨

int ih_v6_1_irq_init (struct amdgpu_device *adev );

---

🌸 ARGUMENTS 🌸

• adev — amdgpu_device pointer. literally that’s the whole argument, no cap 💖

---

🦋 DESCRIPTION 🦋

So here’s the vibe: it allocates a ring buffer for the interrupt controller, enables the RLC, disables interrupts, enables the IH ring buffer and enables it. iconic behavior honestly 💅

It’s called at device load and reume 😭 (that spelling is straight from the page, bestie — I’m not fixing it, I’m just reporting it).

Returns 0 for success, and errors for failure. slay when it works, errors when it doesn’t 🎀
