ENUM DL_DEV_STATE(9)

💅 enum dl_dev_state(9) 💅

Okay so this is from the Kernel API Manual bestie, and it's genuinely one of the cutest little enums you'll ever meet — it's literally just device driver presence tracking information, no cap. Like, it's the enum that answers the question "is there a driver on this device or not" and honestly? Iconic behaviour.

---

🌸 NAME 🌸

enum dl_dev_state — device driver presence tracking information.

Periodt. That's the whole job. Tracking whether a driver is there, showing up, attached, or peacing out. 🎀

---

✨ SYNOPSIS ✨

enum dl_dev_state {
    DL_DEV_NO_DRIVER ,
    DL_DEV_PROBING ,
    DL_DEV_DRIVER_BOUND ,
    DL_DEV_UNBINDING

};

Four constants, one enum, zero drama (well, okay, some drama — it's driver binding, there's always drama 😭).

---

🦋 Constants 🦋

These are the four moods this enum can be in, and honestly each one is a whole vibe:

• DL_DEV_NO_DRIVER — literally nobody is here. There is no driver attached to the device. Empty room, lights off, tumbleweed energy 💀
• DL_DEV_PROBING — a driver is probing. It's in its ✨getting to know you✨ era, trying to figure out if it's a match.
• DL_DEV_DRIVER_BOUND — the driver has been bound to the device. They're official, they're committed, main character couple energy 👑🫶
• DL_DEV_UNBINDING — the driver is unbinding from the device. It's giving conscious uncoupling, it's giving "we need to talk", it's giving goodbye 😭💔

Alright bestie, that's the page! It came from ./include/linux and it's dated October 2026 — so it's from the future, which is honestly so on brand for the kernel ✨💖 Stay bound, stay slaying, and don't forget to unbind gracefully 🌈⭐
