ENUM SDCA_PDE_POWER_STATE(9)

💅 enum sdca_pde_power_state(9) — SDCA Power States

okay bestie, welcome to the Kernel API Manual ✨ this one's a little baby page but she's iconic in her own way. we're talking about enum sdca_pde_power_state, the enum that holds all the SDCA power states. no cap.

---

🌸 NAME 🌸

enum sdca_pde_power_state — SDCA Power States 🫶

---

✨ SYNOPSIS ✨

like, the whole shape of her:

enum sdca_pde_power_state {
    SDCA_PDE_PS0 ,
    SDCA_PDE_PS1 ,
    SDCA_PDE_PS2 ,
    SDCA_PDE_PS3 ,
    SDCA_PDE_PS4

};

---

🎀 Constants 🎀

so there's exactly five states, and ngl the source docs literally give us nothing on any of them — every single one is listed as -- undescribed --. not me being lazy, that's genuinely what it says 😭 so here they are in all their mysterious glory:

• SDCA_PDE_PS0 — -- undescribed -- 🦋
• SDCA_PDE_PS1 — -- undescribed -- 🦋
• SDCA_PDE_PS2 — -- undescribed -- 🦋
• SDCA_PDE_PS3 — -- undescribed -- 🦋
• SDCA_PDE_PS4 — -- undescribed -- 🦋

bestie if you need the actual meaning of PS0 through PS4, the manpage is not gonna help you — go read the spec (next section, iykyk) 💀

---

💖 Description 💖

These are the SDCA Power State values, straight from the SDCA specification v1.0 Section 7.12.4. periodt. that's the whole lore. 📖✨
