ENUM SDCA_UMP_MODE(9)

💅 enum sdca_ump_mode(9) — SDCA UMP Mode, kernel API manual edition ✨

okay so bestie, we're in the Kernel API Manual today and the main character of this page is literally enum sdca_ump_mode — the SDCA UMP Mode situation 🎀 it lives in the kernel file ./include/sound/sdca_function.h, so that's the vibe check on where to find it 🦋

---

🌸 NAME 🌸

enum sdca_ump_mode — SDCA UMP Mode. that's it, that's the name, no notes 💅

---

✨ SYNOPSIS ✨

here's the whole shape of it, copied exactly so you can't mess it up:

enum sdca_ump_mode {
    SDCA_UMP_MODE_DIRECT ,
    SDCA_UMP_MODE_INDIRECT

};

two constants, one enum, periodt 💖

---

🫶 Constants 🫶

okay so the docs for these are literally empty and i'm not gonna lie to you about it:

• SDCA_UMP_MODE_DIRECT — -- undescribed -- 😭 the manpage said nothing. zero. nada. the lore is not there yet.
• SDCA_UMP_MODE_INDIRECT — also -- undescribed -- 🙈 same energy, also a mystery.

fr fr, i'm not out here inventing behaviour for you — the source literally lists these as undescribed, so no cap, that's all we've got 💀
