iceland_ih_e...e_interrupts(9)

💖 iceland_ih_enable_interrupts — like, the whole page, bestie 💖

okay so this is a Kernel API Manual page (section 9, iykyk) for iceland_ih_enable_interrupts, and the way I'm gonna explain it is we're gonna go through every single line together, no skipping, no cap 🫶

✨ NAME ✨

iceland_ih_enable_interrupts — enable the interrupt ring buffer 🌸

that's it. that's the whole vibe. it turns the thing on 💅

---

🎀 SYNOPSIS 🎀

void iceland_ih_enable_interrupts (struct amdgpu_device *adev );

so it returns void (nothing comes back, it's giving "i did the thing, don't ask me for receipts") and it takes exactly one argument. one. singular. main character argument energy 👑

---

🦋 ARGUMENTS 🦋

• adev — an amdgpu_device pointer. literally just the device handle you're passing in, bestie. that's the whole argument. that's the moment. ✨

---

💜 DESCRIPTION 💜

Enable the interrupt ring buffer (VI). 🔥

okay so lowkey that's the entire description and it's iconic for it. you call this function and the interrupt ring buffer gets enabled. VI is doing a lot of heavy lifting in that sentence and we're just gonna let it cook 🍓
