STRUCT TTM_BUS_PLACEMENT(9)

🌸 struct ttm_bus_placement(9) 🌸

okay bestie, welcome to the Kernel API Manual — this one's a struct page, so grab a lil snack and let's get into it 🍓

---

✨ NAME ✨

struct ttm_bus_placement — that's it, that's the name 💅 (the original page literally leaves the description blank here, so we're not gonna invent one, iykyk)

---

🦋 SYNOPSIS 🦋

struct ttm_bus_placement {
    void *addr;
    phys_addr_t offset;
    bool is_iomem;
    enum ttm_caching        caching;
 };

like, that's the whole vibe. four fields, zero drama ✨

---

👑 Members 👑

• addr — the mapped virtual address, fr fr 🫶
• offset — the physical addr
• is_iomem — is this io memory ? (yes, with the space before the question mark, we keep it iconic 😭)
• caching — See enum ttm_caching — go look at that enum, bestie, it's got the lore 🌈

---

💖 Description 💖

So the way that this works: it's a structure indicating the bus placement of an object. that's the whole assignment. main character energy for a struct that just holds placement info 👑
