ttm_resource_init(9)

💅 NAME 💅

ok so bestie, welcome to ttm_resource_init(9) — that's the Kernel API Manual page for this one ✨ it's literally the resource object constructor, the little function that gets your resource born into the world 🎀 iykyk

---

✨ SYNOPSIS ✨

void ttm_resource_init (struct ttm_buffer_object *bo , const struct
ttm_place *place , struct ttm_resource *res );

no cap, that's the whole signature — copy it exactly, don't get creative with it 🙈

---

🫶 ARGUMENTS 🫶

• bo — the buffer object this resource is being allocated for. it's the whole reason we're here 💖
• place — where the resource is placed, its placement, its whole location vibe 🌸
• res — the resource object you're actually initializing. the main character of this call 👑

---

🦋 DESCRIPTION 🦋

okay so picture this: you got a brand new resource object and it's just sitting there, uninitialized, giving nothing. ttm_resource_init is the glow-up ✨ it initializes a new resource object, periodt.

and because every good thing has a counterpart (😭), it's the counterpart of ttm_resource_fini. init and fini, the iconic duo, the way that they just balance each other 🎀
