💅 cik_ih_enable_interrupts(9) — like, the Kernel API Manual page, bestie

Okay so we're in the Kernel API Manual, section 9, and today's main character is cik_ih_enable_interrupts. Buckle up 🎀

✨ NAME ✨

cik_ih_enable_interrupts — turn the interrupt ring buffer on. That's it. That's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

void cik_ih_enable_interrupts (struct amdgpu_device *adev );

Not me copying this character for character including that little space before the closing paren — yes bestie, exactly like that 💅

---

✨ ARGUMENTS ✨

• adev — an amdgpu_device pointer. That's the whole arg. One pointer, no cap 🫶

---

✨ DESCRIPTION ✨

So basically this function enables the interrupt ring buffer, and the (CIK) in the original is doing a lot of heavy lifting — that's the context this call lives in, periodt. Enable = on. The interrupt ring buffer = enabled. Slay. ⭐
