✨ ih_v6_0_irq_init(9) ✨

okay so welcome to the Kernel API Manual, bestie — this is the page for ih_v6_0_irq_init(9), and we’re gonna make the interrupt ring make sense. 🎀

---

🌸 NAME 🌸

ih_v6_0_irq_init — init and enable the interrupt ring. periodt. ✨

---

🦋 SYNOPSIS 🦋

int ih_v6_0_irq_init (struct amdgpu_device *adev );

No cap, that’s the whole signature. 🫶

---

💅 ARGUMENTS 💅

• adev — amdgpu_device pointer. That’s the one and only argument, bestie. 👑

---

🔥 DESCRIPTION 🔥

okay so here’s the vibe: this function allocates a ring buffer for the interrupt controller, enables the RLC, disables interrupts, enables the IH ring buffer, and then enables it. ✨

It’s called at device load and reume — yes, that’s exactly how the page spells it, iykyk. 😭

Returns 0 for success, errors for failure. That’s the whole mood: zero is slay, anything else is not. 💀
