STRUCT AC97_CONTROLLER_OPS(9)

💅 struct ac97_controller_ops(9) ✨

okay bestie, welcome to the Kernel API Manual entry for struct ac97_controller_ops — the AC97 operations, and honestly? iconic.

---

🎀 NAME 🎀

struct ac97_controller_ops — literally just the AC97 operations. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

here's the struct, bestie, copy it exactly, no cap:

struct ac97_controller_ops {
    void (*reset)(struct ac97_controller *adrv);
    void (*warm_reset)(struct ac97_controller *adrv);
    int (*write)(struct ac97_controller *adrv, int slot, unsigned short
reg, unsigned short val);
    int (*read)(struct ac97_controller *adrv, int slot, unsigned short
reg);
 };

---

💖 Members 💖

• reset — cold reset of the AC97 AC-Link. like a full factory reset, no survivors 💀
• warm_reset — warm reset of the AC97 AC-Link. softer, gentler, still resetting 🫶
• write — writes a single AC97 register. one (1) register. very demure 🌸
• read — reads a single AC97 register. returns the register value, or a negative error code if things went sideways 😭

---

👑 Description 👑

so these are the basic operations that an AC97 controller must provide for the AC97 access functions. lowkey the whole point. 🔥

amongst these, all but the last 2 are mandatory. so reset and warm_reset? mandatory, periodt. the last two (write and read)? the vibes say optional. 💅

also, the slot number is what they call the AC97 codec number, and it's between 0 and 3. yes, only 0–3, that's the range, don't push it 🎀
