vcn_v1_0_enc...g_emit_fence(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

vcn_v1_0_enc_ring_emit_fence — bestie, this one emits an enc fence, and a trap command 🎀 (like, both, in one go, no cap)

🌸 SYNOPSIS 🌸

void vcn_v1_0_enc_ring_emit_fence (struct amdgpu_ring *ring , u64 addr ,
       u64 seq , unsigned flags );

okay so that's the whole signature, and yes you literally pass all four of those, in that order, periodt 💅

🦋 ARGUMENTS 🦋

  • ring — an amdgpu_ring pointer 💫 your lil ring struct, the one we're writing to
  • addr — the address 🏠 like, the one the fence points at
  • seq — the sequence number 🔢 the number that keeps everything in order, iykyk
  • flags — the fence related flags 🚩 all the fence-adjacent flag bits live here

💜 DESCRIPTION 💜

So basically — and hear me out — this function writes an enc fence and a trap command into the ring. That's it. That's the whole vibe ✨

Like, it takes those args and goes "here's your fence, here's your trap, ring, do your thing" 🫶 The way that it's literally just writing two things to the ring and dipping 😭
