STRUCT SOF_IPC4_GAIN_PARAMS(9)

💅 struct sof_ipc4_gain_params(9) 💅

okay bestie, welcome to the Kernel API Manual, page struct sof_ipc4_gain_params(9) — yes that's the whole title, we're being extra about it today 🎀

---

✨ NAME ✨

struct sof_ipc4_gain_params — the IPC gain parameters struct. literally what it says on the tin, no cap 💖

---

🌸 SYNOPSIS 🌸

here's the whole vibe, character for character, don't touch a single char bestie:

struct sof_ipc4_gain_params {
    uint32_t channels;
    uint32_t init_val;
    uint32_t curve_type;
    uint32_t reserved;
    uint32_t curve_duration_l;
    uint32_t curve_duration_h;
 };

---

👑 Members 👑

okay so let's meet the cast, each one is kinda iconic in its own way 🫶

• channels — Channels. that's it, that's the whole description, she's mysterious like that ✨
• init_val — Initial value. the starting point, the origin story, the before pic 📸
• curve_type — Curve type. which flavor of curve we're dealing with 🌀
• reserved — reserved for future use. she's not doing anything rn but she's reserved, like a table at a nice restaurant 🍓
• curve_duration_l — Curve duration low part. the low half of the curve duration, keep her safe 💜
• curve_duration_h — Curve duration high part. and the high half, together they're a matched set 🦋

💀 reminder bestie: reserved is reserved for future use, so don't be out here using it for your own lil experiments, she's got plans okay 🙈

mwah, that's the page! this lil number lives in ./sound/soc/sof and it's serving October 2026 energy — and yes, the page name is still struct sof_ipc4_gain_params(9), she's consistent 👑✨💖
