📦 version 7.3.1, in nixpkgs unstable

💅 amdgpu_uvd_cs_msg_decode (9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this one lives in the Kernel API Manual and it's all about poking at UVD decode messages — the vibe is very "graphics driver internals" and honestly? iconic. let's get into it ✨

🌸 NAME 🌸

amdgpu_uvd_cs_msg_decode — handle UVD decode message 🦋

✨ SYNOPSIS ✨

int amdgpu_uvd_cs_msg_decode (struct amdgpu_device *adev , uint32_t *msg
, unsigned int buf_sizes[] );

like, that's the whole signature, no notes 💅

🎀 ARGUMENTS 🎀

  • adev — amdgpu_device pointer 👑 (the device in question, obvi)
  • msg — pointer to message structure 📨 (the message we're peeking at)
  • buf_sizes — placeholder to put the different buffer lengths 🍓 (she's holding space for the numbers, literally)

🔥 DESCRIPTION 🔥

Peek into the decode message and calculate the necessary buffer sizes. 🧚

that's it, that's the whole job — she looks inside the message, does the math on what buffers are gonna be needed, and writes the sizes into the placeholder. lowkey essential, highkey underrated. periodt. 💜
