ENUM SDCA_SU_CONTROLS(9)

👑 enum sdca_su_controls(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for enum sdca_su_controls, aka the SDCA Controls for Selector Unit. it's giving "small but mighty" ✨

---

🌸 NAME 🌸

enum sdca_su_controls — SDCA Controls for Selector Unit. literally what it says on the tin, no cap 🎀

---

🦋 SYNOPSIS 🦋

enum sdca_su_controls {
    SDCA_CTL_SU_SELECTOR ,
    SDCA_CTL_SU_LATENCY

};

that's the whole thing. two members, zero drama 💜

---

✨ Constants ✨

so here's the lineup, and yes they are exactly this iconic:

• SDCA_CTL_SU_SELECTOR — this one has no description in the source. -- undescribed --, and honestly? mysterious main character energy 🕵️‍♀️ the original literally just says -- undescribed --, so i'm not gonna make up lore for it fr fr.
• SDCA_CTL_SU_LATENCY — same situation bestie, -- undescribed -- is all we get. she's an enigma, we respect it 🙈

ngl, "-- undescribed --" is doing a lot of heavy lifting here. it means the docs themselves didn't spell these out, so please don't come for me — i'm just the messenger 🫶

---

💖 Description 💖

these are the Control Selectors for the Selector Unit, straight outta the SDCA specification v1.0 section 6.3.8.3. that's the whole vibe check — control selectors, selector unit, spec v1.0, section 6.3.8.3. periodt 📚✨

lowkey that's a lot of links but every single one is here, i checked twice bestie 💅

and that's a wrap!! this page lives at ./include/sound and it's dated October 2026 — yeah, from the future, iconic behavior honestly ⭐🦋 slay, go read sdca_function.h and stan the selector unit 💖🎀
