✨ radeon_irq_kms_init(9) ✨

okay so this is a page from the Kernel API Manual and honestly? it's a little one but she's important 💅 this one is all about radeon_irq_kms_init — the function that gets your driver's interrupt info all set up and cute. let's get into it, bestie 🫶

---

🌸 SYNOPSIS 🌸

int radeon_irq_kms_init (struct radeon_device *rdev );

literally one argument, one return value, no drama 💖

---

🎀 ARGUMENTS 🎀

• rdev — the radeon device pointer. that's it, that's the whole argument. she's the radeon device, she's the main character 👑

---

🦋 DESCRIPTION 🦋

so what does she actually do? she sets up the work irq handlers, the vblank init, the MSIs, etc. — and yes, that's across all asics (every single one of them, no cap) ✨

and the return sitch? she returns 0 for success 🎉 and an error for failure 😭 so like, always check her, okay? don't just ignore the return value and then act surprised. vibe check your error codes, fr fr.
