okay so we're in the Kernel API Manual bestie, and this one is a whole little function about making a drm_pagemap cache. short page, but iconic. let's get into it 🫶

✨ NAME ✨

xe_pagemap_cache_create — literally just: create a drm_pagemap cache. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int xe_pagemap_cache_create (struct xe_tile *tile );

no cap, that's it. one argument, one return value, we love a low-effort signature 💅

---

🦋 ARGUMENTS 🦋

• tile — the tile you're registering the cache with. like, this is the tile. the cache goes here. that's the whole relationship 💖

---

⭐ DESCRIPTION ⭐

so what does it actually do?? it creates a drm_pagemap cache and registers it with the tile. yes bestie, both things. create + register. it's giving "one function, two jobs" and honestly? slay. 🔥

---

🌈 RETURN 🌈

• 0 — success!! we ate 💅✨
• negative error code — failure 😭 it's negative, so like, not great. check it, always.
