amdgpu_irq_handler(9)

💅 amdgpu_irq_handler(9) 💅

okay so this is straight out of the Kernel API Manual, bestie — we're talking the amdgpu_irq_handler page, and it's lowkey iconic. sit down, grab a strawberry drink 🍓, let's get into it.

---

✨ NAME ✨

amdgpu_irq_handler — the IRQ handler. that's it, that's the whole name. short queen behavior 👑

---

✨ SYNOPSIS ✨

irqreturn_t amdgpu_irq_handler (int irq , void *arg );

like literally that's the whole signature, no notes 💅

---

✨ ARGUMENTS ✨

• irq — the IRQ number. and bestie… it's unused. yes, it's there, yes it's in the signature, no, nobody's looking at it. it's giving decoration 🎀
• arg — a pointer to the DRM device. this one's the main character, this is the actual payload fr fr 👑

---

✨ DESCRIPTION ✨

so what does it do? it's the IRQ handler for the amdgpu driver — and the important part, the part that ate: all ASICs. every single one. no exceptions, no crumbs left behind. 🌈

---

✨ RETURN ✨

it returns the result of handling the IRQ, as defined by irqreturn_t. that's the vibe check on whether the interrupt got handled — whatever irqreturn_t says goes, and irqreturn_t does not elaborate 😭

---
