✨ NAME ✨

uvd_v5_0_ring_emit_fence — emit an fence & trap command 🚧✨

(yes, "an fence" — the original said it like that and I'm not about to gaslight you, fr fr)

---

🌸 SYNOPSIS 🌸

void uvd_v5_0_ring_emit_fence (struct amdgpu_ring *ring , u64 addr , u64
seq , unsigned flags );

so it's a void function — meaning it hands nothing back, it just does the thing and leaves, main character energy honestly 💅

🦋 ARGUMENTS 🦋

• ring — an amdgpu_ring pointer 🌀 like, this is the ring we're writing into, bestie
• addr — the address 📍
• seq — the sequence number 🔢
• flags — the fence related flags 🚩 (fence-adjacent flags, if you will)

---

🔥 DESCRIPTION 🔥

Write a fence and a trap command to the ring. that's it, that's the whole vibe. two commands, one function, no cap 🫶

ngl there's nothing dangerous or deprecated in here, it's just a lil fence-and-trap emitter. still, respect the ring, okay? 💜
