STRUCT AC97_CONTROLLER(9)

✨ struct ac97_controller — the AC97 controller of the AC-Link ✨

okay bestie, so this one's a kernel API manual page for struct ac97_controller, and it's literally the main character of the AC-Link situation 💅 it lives in the Kernel API Manual, so you know it's the real deal 🎀

🌸 SYNOPSIS 🌸

like, here's the whole shape of it, no cap:

struct ac97_controller {
    const struct ac97_controller_ops *ops;
    struct list_head controllers;
    struct device adap;
    int nr;
    unsigned short slots_available;
    struct device *parent;
    struct ac97_codec_device *codecs[AC97_BUS_MAX_CODECS];
    void *codecs_pdata[AC97_BUS_MAX_CODECS];
 };

copy it exactly, bestie, every character matters 🫶

🦋 Members 🦋

• ops — the AC97 operations ✨ like the whole to-do list of what this controller can actually do.
• controllers — linked list of all existing controllers 🔗 yes, all of them, holding hands in a list.
• adap — the shell device ac97-d, i.e. the ac97 adapter 👑 it's giving adapter energy.
• nr — the number of the shell device 🔢 literally just its number.
• slots_available — the mask of accessible/scanable codecs 🎀 a lil mask that says which codecs we can reach and scan.
• parent — the device providing the AC97 controller 🌈 the parent device, the one who brought it into this world.
• codecs — the 4 possible AC97 codecs (NULL if none found) 💖 four slots, and if nothin's there it's NULL, periodt.
• codecs_pdata — platform_data for each codec (NULL if no pdata) 🍓 same deal, per-codec platform data, and NULL when there's none.

💜 Description 💜

so listen 🙈 this structure is internal to AC97 bus, and it should not be used by the controllers themselves — the only exception being using dev. that's it. that's the whole vibe check. no cap, don't go grabbing at the internals, bestie, it's not for you 😭
