ENUM TTM_LRU_ITEM_TYPE(9)

💅 enum ttm_lru_item_type(9) — bestie's field guide to the TTM LRU item gang

okay so this is the ttm_lru_item_type page from the Kernel API Manual, and it's honestly such a short one that you could read it in the time it takes your iced coffee to arrive 🧋 — but it's important, so let's get into it.

The whole vibe of this enum? It's literally just a lil name-tag system. ttm_lru_item has subclasses, and this enum is the way we tell them apart. No cap, that's the entire plot 🎀

---

✨ NAME ✨

enum ttm_lru_item_type — enumerate ttm_lru_item subclasses 🦋

---

🌸 SYNOPSIS 🌸

enum ttm_lru_item_type {
    TTM_LRU_RESOURCE ,
    TTM_LRU_HITCH

};

that's it, that's the whole thing. two constants, both living rent-free in the enum. iconic behavior honestly 👑

---

💖 Constants 💖

• TTM_LRU_RESOURCE — the resource subclass 💅 that's the one that's all about resources.
• TTM_LRU_HITCH — the iterator hitch subclass 🌈 the hitch, but make it iterator.

fr fr the whole enum is just these two, so if you were bracing for a long list — nope. two items. we ate and left no crumbs.

---

🔥 SEE ALSO 🔥

the kernel file lives at ./include/drm/ttm/ttm_resource.h — go say hi to it, it's the source of truth 💜

and here's the whole friend group, in the order they were introduced, because we don't skip anyone in this house 🫶

• TTM_NUM_MOVE_FENCES(9)
• struct ttm_lru_item(9)
• ttm_lru_item_init(9)
• struct ttm_resource_manager(9)
• struct ttm_bus_placement(9)

• ttm_resource_manager_set_used(9)
• ttm_resource_manager_used(9)
• ttm_resource_manager_cleanup(9)
• ttm_resource_manager_for_each_res(9)

like, that's a packed SEE ALSO section. main character energy from every single one of them ngl ⭐

so yeah, that's the page 💖 it shipped out from ./include/drm/ttm back in October 2026, and it's been slaying ever since. go forth, tell your subclasses apart, and remember — TTM_LRU_RESOURCE and TTM_LRU_HITCH, that's the whole roster. periodt. 🎀✨💅
