STRUCT TTM_KMAP_ITER(9)

💅 struct ttm_kmap_iter(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this one is short but it's giving "small but mighty," and honestly? iconic.

---

✨ NAME ✨

struct ttm_kmap_iter — an iterator for kmap_local-type operations on a resource. lowkey a little struct with main character energy 💖

---

🦋 SYNOPSIS 🦋

struct ttm_kmap_iter {
    const struct ttm_kmap_iter_ops *ops;
};

---

💖 Members 💖

• ops — pointer to the operations struct. that's the member, bestie, the whole struct is literally this one pointer and we stan a minimalist 👑

---

🌸 Description 🌸

This struct is intended to be embedded in a resource-specific specialization that implements operations for the resource. so like, it's not out here doing solo performances — it gets tucked inside a bigger, resource-specific situation and does its thing from there 🫶

Nothing stops us from extending the operations to vmap, vmap_pfn etc, replacing some or parts of the ttm_bo_util. cpu-map functionality. no cap, that's literally what the docs say — the door is open for expansion, iykyk 🚪✨

👑 SEE ALSO 👑

• Kernel file ./include/drm/ttm/ttm_kmap_iter.h
• struct ttm_kmap_iter_ops(9)

that's the whole page, bestie — short, sweet, and absolutely slaying in that low-level kernel way 💅✨
