okay so bestie, welcome to the Kernel API Manual 💖 this one's a little function from the radeon crew and it's literally just here to answer one very dramatic question: is the graphics engine having a moment? 🫶

🌸 NAME 🌸

evergreen_gfx_is_lockup — check if the GFX engine is locked up 💀

---

🦋 SYNOPSIS 🦋

bool evergreen_gfx_is_lockup (struct radeon_device *rdev , struct
       radeon_ring *ring );

like, two args, one bool out, no cap ✨

---

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer 👑 it's giving "the whole device, bestie"
• ring — a radeon_ring structure holding ring information 🌀 this one's got the ring deets

---

💅 DESCRIPTION 💅

So the whole vibe here is: check if the GFX engine is locked up. That's it, that's the job 🧚

It returns true if the engine appears to be locked up 😭 and false if not 🌈

ngl it's an "appears to be" situation — the manpage says it like that, so we say it like that 💜
