🌸 NAME 🌸

si_gfx_is_lockup — checks whether the GFX engine is locked up, no cap 🔥

---

✨ SYNOPSIS ✨

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

literally that's the whole vibe: you hand it a rdev and a ring, and it gives you back a bool 🫶

🎀 ARGUMENTS 🎀

• rdev — a radeon_device pointer. that's the whole device situation, she's the main character 👑
• ring — the radeon_ring structure holding ring information. that's where the ring's details live 💖

💜 DESCRIPTION 💜

so what does it actually do? it checks if the GFX engine is locked up 🔍

returns true if the engine appears to be locked up, and false if not. that's it, that's the function — simple, iconic, periodt 💅

ngl, "appears to be" is doing a lot of work in that sentence, bestie — be chill about it 🌸
