drm_edid_to_sad(9)

📦 version 7.3.1, in nixpkgs unstable

💅 drm_edid_to_sad(9) — like, the Kernel API Manual bestie ✨

okay so picture this: you're deep in the kernel, you've got a drm_edid_to_sad(9) situation, and nobody's explaining it in a way that actually slaps. that's what i'm here for 🫶 (it's from the Kernel API Manual, iykyk)

✨ NAME ✨

drm_edid_to_sad — extracts SADs from EDID 💖

🌸 SYNOPSIS 🌸

int drm_edid_to_sad (const struct edid *edid , struct cea_sad **sads );

🎀 ARGUMENTS 🎀

  • edid — the EDID you want parsed, bestie. that's the thing going in 🔍
  • sads — a pointer that will be set to the extracted SADs. it gets pointed at the goods ✨

🦋 DESCRIPTION 🦋

so what does it actually do? it goes looking for the CEA EDID block, and then it extracts the SADs (Short Audio Descriptors) out of it. that's the whole vibe 💅 literally: find the block, pull the SADs.

💀 NOTE 💀

⚠️ the returned pointer needs to be freed using kfree. no cap — if you forget, that's a leak, and leaks are not the moment 🙈

⭐ RETURN ⭐

it gives you back the number of found SADs, or a negative number on error. so like, negative = it's giving bad news 😭
