STRUCT XE_GGTT_NODE(9)

🎀 struct xe_ggtt_node(9) 🎀

Okay bestie, this is the Kernel API Manual page for struct xe_ggtt_node — literally a node in GGTT. Let's get into it. 💅

---

✨ NAME ✨

struct xe_ggtt_node — a node in GGTT. Periodt. 👑

---

🌸 SYNOPSIS 🌸

struct xe_ggtt_node {
    struct xe_ggtt *ggtt;
    struct drm_mm_node base;
    struct work_struct delayed_removal_work;
    bool invalidate_on_remove;
};

---

👑 MEMBERS 👑

• ggtt — back pointer to the xe_ggtt where this region will be inserted at. It's giving "I know exactly where I belong" energy. 🫶
• base — a drm_mm_node. Literally just that. No cap. ✨
• delayed_removal_work — the work_struct for the delayed removal. The little work bestie handling the later goodbye. 💖
• invalidate_on_remove — if it needs invalidation upon removal. Bool vibes only. 💅

---

💅 DESCRIPTION 💅

This struct is allocated with xe_ggtt_insert_node(,_transform) or xe_ggtt_insert_bo(,_at). It will be deallocated using xe_ggtt_node_remove.

That's the lifecycle, and honestly? iconic. 🎀
