ENUM DRM_INTERCONNECT_PROTOCOL(9)

💅 enum drm_interconnect_protocol(9) 💅

okay so bestie, welcome to the enum drm_interconnect_protocol page in the Kernel API Manual — yes that's the whole manual name, we're being official today 🎀 — and honestly? this one is short and sweet, so you can absolutely read it before your iced coffee melts.

---

✨ NAME ✨

enum drm_interconnect_protocol — literally just here to identify an interconnect protocol. that's it. that's the job. she's an enum, she's doing her little task, and she's slaying 🦋

---

🌈 SYNOPSIS 🌈

enum drm_interconnect_protocol {
    DRM_INTERCONNECT_SYSTEM ,
    DRM_INTERCONNECT_DRIVER

};

look at her. two members. clean lines. main character energy, no cap 👑

🌸 Constants 🌸

okay so these are the two constants you can actually pick from, and ngl they're giving "two paths diverged in a wood" 🧚

• DRM_INTERCONNECT_SYSTEM — the DMA map is system pages. that's the whole vibe, fr fr.
• DRM_INTERCONNECT_DRIVER — the DMA map is driver defined. so the driver is the one calling the shots here 💅

lowkey the entire enum is just these two options, so if you were bracing for a long list — breathe, bestie, you're safe 😭
