cik_irq_disable(9)

💅 cik_irq_disable(9) 💅

okay bestie, welcome to the Kernel API Manual — yes, this is a kernel manpage, and yes, it's serving real "I read dmesg for fun" energy. buckle up 🎀

---

✨ NAME ✨

cik_irq_disable — literally just: disable interrupts. that's the whole vibe. 🔥

---

🌸 SYNOPSIS 🌸

void cik_irq_disable (struct radeon_device *rdev );

one function, one pointer, zero drama. periodt.

---

🦋 ARGUMENTS 🦋

• rdev — a radeon_device pointer. that's it, that's the whole parameter. she's a pointer to the radeon device and she knows it 👑

---

💖 DESCRIPTION 💖

so what does she actually do? she disables interrupts on the hw (CIK). that's the tea. no cap, that's the entire description — interrupts: off. hardware: CIK. iconic, lowkey minimalist behavior honestly 🫶

ngl this is one of those functions where the manpage is shorter than the function name. respect. 💀

and that's the page!! mwah 💋 this lil api doc lives in ./drivers/gpu/drm/radeon and it's dated October 2026 — so yeah, she's from the future, and she's still just disabling interrupts. slay, honestly. stay hydrated and don't forget to re-enable them later, bestie 🍓✨
