ttm_resource_manager_init(9)

💖 ttm_resource_manager_init — Kernel API Manual, but make it cute ✨

okay so this is ttm_resource_manager_init(9) from the Kernel API Manual — yeah, kernel docs have their own manual section and it's lowkey iconic of them. this is the page for the function ttm_resource_manager_init, and bestie, we're gonna get you fluent in it 🫶

---

🌸 NAME 🌸

ttm_resource_manager_init — and that's it. fr fr, the description part after the dash is literally empty in the original. not a single word. the kernel just put a dash and dipped 😭 so no cap, there's nothing hiding there, that's the whole name entry 💀

---

✨ SYNOPSIS ✨

the shape of it, verbatim, don't touch anything:

void ttm_resource_manager_init (struct ttm_resource_manager *man ,
struct ttm_device *bdev , uint64_t size );

so it returns void — meaning it hands you nothing back, it just does the thing and you move on 💅

---

🎀 ARGUMENTS 🎀

three args, each one doing its own little job:

• man — the memory manager object you're initializing. this is the main character of the whole call 👑
• bdev — the ttm device that this manager belongs to. like, which device's world this manager lives in 🦋
• size — the size of the managed resources, in arbitrary units. yes. arbitrary units. the kernel said "units" and refused to elaborate 🙈

---

💜 DESCRIPTION 💜

here's the whole vibe: this function initializes the core parts of a manager object. that's the entire description, bestie — it's a short one, but it ate and left no crumbs. it's giving "setup function," it's giving "first thing you call," it's giving prerequisites ✨

so when you've got a struct ttm_resource_manager sitting there all uninitialized and sad, this is the glow-up moment where it gets its core bits set up 🧚

⚠️ note: the manpage does not say what happens if you call this twice, or on garbage, or with a nonsense size. so don't go making up lore. we report, we don't invent 💀
