💅 snd_ac97_write_cache(9) 💅

Okay bestie, welcome to the Kernel API Manual — this one's a lil function called snd_ac97_write_cache, and honestly? She's a keeper. Let's get into it ✨

---

🌸 NAME 🌸

snd_ac97_write_cache — writes a value onto the given register and keeps the cache in on the tea, no cap.

---

🎀 SYNOPSIS 🎀

void snd_ac97_write_cache (struct snd_ac97 *ac97 , unsigned short reg ,
       unsigned short value );

---

🦋 ARGUMENTS 🦋

• ac97 — the ac97 instance, aka the main character of this whole operation 🫶
• reg — the register you're about to change, like the exact spot you're editing 💅
• value — the value you're setting it to. Slay.

---

✨ DESCRIPTION ✨

So basically: this writes a value on the given register and updates the register cache at the same time. Two birds, one iconic move 💖

And why do we care about the cache? Because those cached values are literally what gets used for the cached-read and for suspend/resume. So like… the cache is not just vibes, it's load-bearing. Keep her fed 🍓
