STRUCT SOF_IPC4_GAIN_DATA(9)

✨ NAME ✨

Okay bestie, so this is the manpage for struct sof_ipc4_gain_data(9) — literally the IPC gain init blob, and it's giving "main character energy" in the audio firmware world 💅. If you're here, you probably need to know what goes into setting up a gain module, and I'm gonna walk you through it like we're on FaceTime. No cap.

🌸 SYNOPSIS 🌸

struct sof_ipc4_gain_data {
    struct sof_ipc4_base_module_cfg base_config;
    struct sof_ipc4_gain_params params;
};

👑 Members 👑

• base_config — the IPC base config data, aka the foundational vibe check for your module. You always need this, periodt. It's the lowkey backbone 🫶.
• params — the initial parameters for the gain module. Think of it like the starter settings before you go off and customize things — the default fit, fr fr ✨.

🌈 SEE ALSO 🌈

If you're nosy (same) and want the whole friend group this struct hangs with, here's the full list — and yes, every single one is invited to the party 🎀:

Not me lowkey being obsessed with how clean this struct is — two members and it's already slaying 🧚. If you forget any of the SEE ALSO references, just know they're all in the same kernel file, living their best lives together 💖.

This page lives in the ./sound/soc/sof directory, last touched in October 2026, and it's brought to you by the struct sof_ipc4_gain_data(9) girlies. Bye bestie — go make some iconic audio firmware 💫🦋.
