ENUM MEI_DEV_KIND(9)

💅 enum mei_dev_kind(9) — like, the device type enum, bestie

okay so this is from the Kernel API Manual (that's the manual name, keeping it cute and official up top ✨). It's a little baby enum that literally just says what kind of device is this thing — and honestly? It ate. Let's get into it 🫶

---

🌸 SYNOPSIS 🌸

enum mei_dev_kind {
    MEI_DEV_KIND_MEI ,
    MEI_DEV_KIND_ITOUCH ,
    MEI_DEV_KIND_GSC ,
    MEI_DEV_KIND_GSCFI ,
    MEI_DEV_KIND_IVSC ,
    MEI_DEV_KIND_IOE ,
    MEI_DEV_KIND_MAX

};

like yes, that trailing , before the closing brace is just how it is, don't come for it 💀

✨ Constants ✨

okay so here's the whole roster, one by one, no skips, no cap:

• MEI_DEV_KIND_MEI — the basic device. the vanilla of the group, the main character in the most unbothered way 🎀
• MEI_DEV_KIND_ITOUCH — this one's for itouch support. slay 💅
• MEI_DEV_KIND_GSC — discrete graphics content protection. very serious, very protected 🔥
• MEI_DEV_KIND_GSCFI — discrete graphics chassis controller. yes it's a different one from the last one, keep up bestie 😭
• MEI_DEV_KIND_IVSC — visual sensing controller. it sees you 👀
• MEI_DEV_KIND_IOE — IO extender. stretching that IO out, iconic 🌈
• MEI_DEV_KIND_MAX — the sentinel. it's not a real device kind, it's the "we're done here" marker, the end-of-list bouncer 🧚

---

🦋 tiny vibe note: MEI_DEV_KIND_MAX is marked as sentinel — it's the boundary marker for the enum, so don't go treating it like an actual device type, mwah 💖
