ENUM TB_SWITCH_TMU_MODE(9)

💅 enum tb_switch_tmu_mode(9) — like, the TMU mode enum, bestie

Okay so this is a page from the Kernel API Manual and it's about enum tb_switch_tmu_mode — yes the whole name is the title, yes it's a mouthful, we deal. 🫶

✨ NAME ✨

enum tb_switch_tmu_mode — the TMU mode ✨ that's it, that's the name, no cap

🦋 SYNOPSIS 🦋

enum tb_switch_tmu_mode {
    TB_SWITCH_TMU_MODE_OFF ,
    TB_SWITCH_TMU_MODE_LOWRES ,
    TB_SWITCH_TMU_MODE_HIFI_UNI ,
    TB_SWITCH_TMU_MODE_HIFI_BI ,
    TB_SWITCH_TMU_MODE_MEDRES_ENHANCED_UNI

};

🌸 Constants 🌸

Bestie, here's the whole lineup, in order, no skips 💖

• TB_SWITCH_TMU_MODE_OFF — TMU is off. literally just off. nothing happening, we're resting 😴
• TB_SWITCH_TMU_MODE_LOWRES — Uni-directional, normal mode. one direction only, keeping it chill ✨
• TB_SWITCH_TMU_MODE_HIFI_UNI — Uni-directional, HiFi mode. still one direction, but make it fancy 🔥
• TB_SWITCH_TMU_MODE_HIFI_BI — Bi-directional, HiFi mode. both directions now, and HiFi the whole time 👑
• TB_SWITCH_TMU_MODE_MEDRES_ENHANCED_UNI — Enhanced Uni-directional, MedRes mode. enhanced!! medres!! uni-directional!! the whole vibe 🎀

---

💜 Description 💜

The ordering here is based on TMU accuracy level — and the highest accuracy is last, iykyk. So when you're reading down the list, you're climbing the accuracy ladder, and the bottom rung is the most accurate one. ⭐
