💅 ttm_pool_init(9) 💅

ok so this is a page from the Kernel API Manual, and bestie, we are learning how to birth a pool today. yes, a pool. for the TTMs. stay with me ✨

---

✨ NAME ✨

ttm_pool_init — literally just "Initialize a pool" 🏊‍♀️ no cap, that's the whole pitch

---

🎀 SYNOPSIS 🎀

void ttm_pool_init (struct ttm_pool *pool , struct device *dev , int nid
, unsigned int alloc_flags );

like, four args, zero return value, very demure, very void 🫶

---

🌸 ARGUMENTS 🌸

• pool — the pool you're initializing, bestie. your main character. it's the thing getting set up 💖
• dev — the device, and it's the one used for DMA allocations and mappings 👑
• nid — the NUMA node to use for allocations. yes, that NUMA node 🦋
• alloc_flags — the TTM_ALLOCATION_POOL_* flags. the star of the show, the flags, the vibes 🌈

---

✨ DESCRIPTION ✨

okay so what does it actually do? it initializes the pool and its pool types. that's it. that's the sentence. no notes, no extra lore, slay 💅

honestly? iconic behavior. one job, does the job.
