ENUM DRM_XE_OA_UNIT_TYPE(9)

✨ enum drm_xe_oa_unit_type ✨

okay so bestie, this is the enum drm_xe_oa_unit_type page from the Kernel API Manual — yes, the Kernel API Manual, we're literally in the kernel docs together, holding hands 🫶. It's all about OA unit types, and ngl it's a short one but it's giving essential lore, so let's go 💅

---

🌸 NAME 🌸

enum drm_xe_oa_unit_type — the OA unit types, periodt ✨

---

🦋 SYNOPSIS 🦋

enum drm_xe_oa_unit_type {
    DRM_XE_OA_UNIT_TYPE_OAG ,
    DRM_XE_OA_UNIT_TYPE_OAM ,
    DRM_XE_OA_UNIT_TYPE_OAM_SAG ,
    DRM_XE_OA_UNIT_TYPE_MERT

};

look at her, four constants, no drama, we love a clean enum 🎀

---

💖 Constants 💖

• DRM_XE_OA_UNIT_TYPE_OAG — the OAG OA unit ✨ and listen, OAR/OAC are considered sub-types of OAG, so for OAR/OAC you use OAG. like, don't go looking for an OAR constant, bestie, she's not there 🙈 use OAG.
• DRM_XE_OA_UNIT_TYPE_OAM — the OAM OA unit, no cap 💜
• DRM_XE_OA_UNIT_TYPE_OAM_SAG — the OAM_SAG OA unit, she has her own little suffix and we respect it 🌸
• DRM_XE_OA_UNIT_TYPE_MERT — the MERT OA unit, iconic name honestly, main character energy 👑

okay this part is a whole friend group, buckle up 🎀
