📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

drm_edid_to_speaker_allocation — bestie, this one literally extracts the Speaker Allocation Data Blocks out of your EDID, no cap ✨

So you're telling me this is a Kernel API Manual page and nobody told me?? Well now you know 🎀 we're reading the kernel API manual together and it's giving main character energy fr fr.

✨ SYNOPSIS ✨

int drm_edid_to_speaker_allocation(const struct edid *edid, u8 **sadb);

Yeah that's the whole signature, she's cute, she's compact, she does exactly one thing 💖

🫶 ARGUMENTS 🫶

  • edid — the EDID you want to parse. That's it, that's the vibe, hand her the EDID and she'll go look around 🔍
  • sadb — pointer to the speaker block 🙈 that's where the good stuff lands

🌸 DESCRIPTION 🌸

Okay so here's the tea ☕ — she goes looking for the CEA EDID block and then extracts the Speaker Allocation Data Block out of it. That's the whole plot, no subplots, no side quests 🦋

Like… that's genuinely it. Find the block, pull the block. Iconic behaviour from a kernel function ngl 👑

💀 NOTE 💀

⚠️ Not me reminding you AGAIN — but the returned pointer needs to be freed using kfree. If you don't, that's a memory leak and the kernel will be quietly judging you forever 😭 Do your chores bestie, free your pointers 💅

⭐ RETURN ⭐

She returns the number of found Speaker Allocation Blocks, or a negative number on error 💔

So basically: positive = slay, negative = something went wrong and you should probably look at that 🌈

Kernel file ./drivers/gpu/drm/drm_edid.c — that's where she lives 🏠

And now: the friend group 👯‍♀️ literally every cousin in the EDID family, all of them, here we go:

and that's the whole page bestie, you ate that 🍓 💜

Source? ./drivers/gpu/drm obviously, dated October 2026 — written from the future or whatever, we don't question it 🙈🎀 Go forth and free your sadb pointers, iykyk 💅✨
