cik_irq_fini(9)

✨ NAME ✨

cik_irq_fini(9) — okay bestie, this page is from the Kernel API Manual, and it's literally "tear down interrupt support." It's giving cleanup era, no cap. 💅

🛠️ SYNOPSIS 🛠️

void cik_irq_fini (struct radeon_device *rdev );

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer. That's the one and only argument, fr fr. 🫶

💖 DESCRIPTION 💖

Okay so cik_irq_fini disables interrupts on the hw and frees the IH ring buffer (CIK). Slay. It's used for driver unload, so it's your "bye bestie, clean up the interrupt support" moment. ✨

Vibe check: it's a fini/cleanup function — interrupts off on the hw, IH ring buffer freed (CIK), and it's used for driver unload. Periodt. 💀
