radeon_drive...einstall_kms(9)

🌸 NAME 🌸

radeon_driver_irq_preinstall_kms — the drm irq preinstall callback, bestie 💅

(and yes, this is a page out of the Kernel API Manual — we're literally in the kernel trenches today, hold my iced coffee 🧊)

---

✨ SYNOPSIS ✨

void radeon_driver_irq_preinstall_kms (struct drm_device *dev );

---

🫶 ARGUMENTS 🫶

• dev — the drm dev pointer. that's it. that's the whole argument. she's low maintenance 👑

---

💖 DESCRIPTION 💖

Okay so picture this: the hardware is getting ready to actually enable irqs (all asics — every single one of them, no cap), and this function is the one doing the prep work. ✨

What does "prep" mean here, you ask? It disables all interrupt sources on the GPU. Every last one. The whole interrupt guest list gets cancelled, fr fr 🔥

It's giving "lights off, doors locked, nobody comes in until we say so" energy. Iconic, honestly.
