STRUCT HDA_DATA(9)

💖 NAME 💖

okay bestie, welcome to struct hda_data(9) from the Kernel API Manual 💅 this one is literally about struct hda_data — optional device-specific data ✨

🦋 SYNOPSIS 🦋

struct hda_data {
    const char *short_name;
    const char *long_name;
    unsigned long flags;
};

🎀 Members 🎀

• short_name — used for the ALSA card name; defaults to KBUILD_MODNAME 💖
• long_name — used for a longer description; defaults to short_name 🌸
• flags — passed to azx->driver_caps ⭐

✨ Description ✨

so here’s the vibe: a pointer to a record of this type can be stored in the acpi_device_id->driver_data field of an ACPI match table entry, and that’s how you customize the naming and behavior of a particular device 👑

every single field is optional, and sensible defaults will be selected in their absence — no cap, it’s giving low-maintenance icon behavior 🫶

🌈 SEE ALSO 🌈

• Kernel file ./sound/hda/controllers/acpi.c 🔥

and that’s the whole manual, bestie — source/version lives at ./sound/hda/controllers, dated October 2026, and yes this was struct hda_data(9) the entire time 💜🎀
