STRUCT SDCA_FUNCTION_DESC(9)

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual page for struct sdca_function_desc(9) — this is the short descriptor for an SDCA Function. Literally the little summary card for one of these Function cuties. ✨

🦋 SYNOPSIS 🦋

the whole vibe is this struct, and yes, we're keeping it character-for-character:

       struct sdca_function_desc {
           struct fwnode_handle *node;
           struct sdca_dev *func_dev;
           const char *name;
           u32 type;
           u8 adr;
           bool duplicate;
        };

🎀 Members 🎀

okay so here's the cast of characters inside the struct, no cap:

• node — firmware node for the Function. 🌸
• func_dev — pointer to SDCA function device.
• name — Human-readable string. cute and readable, love that.
• type — Function topology type.
• adr — ACPI address (used for SDCA register access).
• duplicate — Internal flag to indicate if other functions of the same type exist. iykyk 👑

mwah 💋 this page lives under ./include/sound, dated October 2026, and it's still struct sdca_function_desc(9) — bye bestie, slay 🫶💖
