vcn_v2_0_enc...g_emit_fence(9)

📦 version 7.3.1, in nixpkgs unstable

🎀 fence-emission station 🎀

Okay bestie, welcome to the Kernel API Manual. This page is all about vcn_v2_0_enc...g_emit_fence(9) — yeah, the header truncates the name like that, it's literally giving "we ran out of character budget" 😭. Anyway, it's a tiny but iconic function from the amdgpu/VCN universe, and we're gonna read it together. 🫶

🌸 NAME 🌸

vcn_v2_0_enc_ring_emit_fence — the main-character move that emits an enc fence & trap command. 💅✨

🦋 SYNOPSIS 🦋

void vcn_v2_0_enc_ring_emit_fence (struct amdgpu_ring *ring , u64 addr ,
u64 seq , unsigned flags );

💖 ARGUMENTS 💖

  • ring — an amdgpu_ring pointer, aka the ring our little function is about to write into. slay 💫
  • addr — the address. just vibes, just a location 📍
  • seq — the sequence number, so everyone stays in order 🔢
  • flags — fence related flags. very fence, very related 🚩

✨ DESCRIPTION ✨

Okay so here's the whole plot: it writes an enc fence and a trap command onto the ring. That's it, that's the function. Short, sweet, and absolutely doing its job. no cap. 🔥
