STRUCT SOF_IPC4_GAIN(9)

💖 struct sof_ipc4_gain(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ this is the page for struct sof_ipc4_gain, and it's literally just "gain config data" — that's the whole NAME section, short and iconic 🎀

🌸 SYNOPSIS 🌸

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

struct sof_ipc4_gain {
    struct sof_ipc4_gain_data data;
    struct sof_ipc4_available_audio_format available_fmt;
    struct sof_ipc4_msg msg;
 };

three members, three vibes, we love a tidy little struct 🫶

✨ MEMBERS ✨

• data — the IPC gain blob 💅 that's it, that's the description, she's a blob and she's serving
• available_fmt — Available audio format 🌈 the format menu, the options, the "what can we actually play" energy
• msg — message structure for gain 💌 the actual message-struct situation for this gain

🦋 SEE ALSO 🦋
