💖 snd_ac97_mixer(9) 💖

okay so this is a page from the Kernel API Manual (section 9, the kernel-functions girlies) and it's all about snd_ac97_mixer — literally the glow-up ritual that summons a Codec97 component into existence ✨

✨ NAME ✨

snd_ac97_mixer — bestie, this is the one that creates an Codec97 component 💅

🌸 SYNOPSIS 🌸

int snd_ac97_mixer (struct snd_ac97_bus *bus , struct snd_ac97_template
*template , struct snd_ac97 **rac97 );

🎀 ARGUMENTS 🎀

  • bus — the AC97 bus which codec is attached to 🚌 like, this is the friend group the codec is joining, no cap.
  • template — the template of ac97, including index, callbacks and the private data. it's giving "here's my whole personality in a struct" energy 🫶
  • rac97 — the pointer to store the new ac97 instance. aka the lil slot where the freshly-made baby gets placed 🙈

🦋 DESCRIPTION 🦋

Creates an Codec97 component. ngl that's the whole gig. An struct snd_ac97 instance is newly allocated and initialized from the template — like, it's built fresh out of the template's whole vibe. The codec is then initialized by the standard procedure. no shortcuts, no skipping steps, periodt 💅

The template must include the codec number (num) and address (addr), and the private data (private_data). must — like, this is not optional, bestie, those three are the bare minimum or it's not gonna slay 😭

The ac97 instance is registered as a low-level device, so you don't have to release it manually. she handles her own cleanup — main character energy fr fr 👑

⭐ RETURN ⭐

Zero if successful, or a negative error code on failure. so like, 0 = ate and left no crumbs, negative = something went 💀 (in the bad way).

🌈 SEE ALSO 🌈

💜 okay that's the whole page, go build your codec, iykyk. remember: template with num, addr and private_data, and don't you dare try to release it manually 😤
