STRUCT AC97_CODEC_DEVICE(9)

💖 NAME 💖

okay so bestie, welcome to struct ac97_codec_device — the Kernel API Manual page for a ac97 codec 🎀 like, it's literally the struct that represents one single codec. that's the whole vibe. no cap. ✨

---

🌸 SYNOPSIS 🌸

here's the shape of it, exactly as it lives, don't touch the code bestie:

struct ac97_codec_device {
    struct device           dev;
    unsigned int            vendor_id;
    unsigned int            num;
    struct clk              *clk;
    struct ac97_controller  *ac97_ctrl;
 };

she's got five members and they all matter, okay? let's meet them 💅

---

🦋 Members 🦋

• dev — the core device. that's it, that's the field. the main character energy of the whole struct 🫶
• vendor_id — the vendor_id of the codec, as sensed on the AC-link. iykyk, it's how the codec introduces itself 🔥
• num — the codec number. 0 is primary, 1 is first slave, etc ... yes the "etc ..." is literally in the docs, it's giving mysterious 💀
• clk — the clock BIT_CLK provided by the codec. she keeps time, she's iconic ⭐
• ac97_ctrl — the ac97 digital controller on the same AC-link. the one actually running the show 👑

---

✨ Description ✨

so here's the tea, bestie: this is the device instantiated for each codec living on a AC-link 🧚 normally there are 0 to 4 codec devices per AC-link, and every single one of them is controlled by an AC97 digital controller. lowkey kinda neat, highkey important 💖

like. 0 to 4. not 5. not 1. 0 to 4. remember it 🎀

💜 SEE ALSO 💜

go read these next, bestie, they're literally right there:

• Kernel file ./include/sound/ac97/codec.h
• struct ac97_id(9)
• struct ac97_codec_driver(9)

---

and that's the whole page, slay 💅 this little gem comes from ./include/sound/ac97, dated circa October 2026 — and it's titled struct ac97_codec_device(9) in the Kernel API Manual, obviously. periodt. 🦋🌸
