ENUM HW_ACC_STATE(9)

✨ enum hw_acc_state(9) ✨

okay bestie, pull up a chair, because we're talking about the kernel API manual page for enum hw_acc_state(9) 🎀 (that's the manual name, btw, she's fancy). This is the little enum that tells a hardware accelerator what mood it should be in. Yes, hardware has moods. We respect them. 💅

---

🌸 NAME 🌸

enum hw_acc_state — the state definition for a hardware accelerator, no cap 🦋

---

⭐ SYNOPSIS ⭐

enum hw_acc_state {
    HW_NO_CHANGE ,
    HW_OFF ,
    HW_OFF_RAMRET ,
    HW_ON

};

Look at her. Four little constants, living their best life. Periodt. 💜

👑 Constants 👑

• HW_NO_CHANGE — literally do nothing, the hardware accelerator state must remain unchanged, leave her alone she's fine 🙈
• HW_OFF — the hardware accelerator must be switched off. bye bestie 💀
• HW_OFF_RAMRET — the hardware accelerator must be switched off with its internal RAM in retention ✨ like she's asleep but still remembers everything, iykyk 🧚
• HW_ON — the hwa hardware accelerator hwa must be switched on. yes, the hwa hardware accelerator hwa. we said it twice because we mean it. main character energy only 🔥

---

🦋 Description 🦋

NOTE! Deprecated 😭 to be removed when all users switched over to use the regulator API.

So yeah — she's iconic but she's on her way out. Don't get too attached. When every last user has switched over to the regulator API, this enum is getting removed fr fr. Not me getting emotional about a deprecation notice 🥲
