amdgpu_ttm_tt_create(9)

💅 amdgpu_ttm_tt_create(9) — a Kernel API Manual moment

okay bestie, so this page is from the Kernel API Manual (section 9, kernel internals, iykyk) and it's all about one little function that makes a ttm_tt object. short page, but she ate ✨

---

🌸 NAME 🌸

amdgpu_ttm_tt_create — literally just: create a ttm_tt object for a given BO. that's the whole job. no cap 💅

---

🦋 SYNOPSIS 🦋

struct ttm_tt * amdgpu_ttm_tt_create (struct ttm_buffer_object *bo ,
uint32_t page_flags );

like yes it returns a struct ttm_tt *, and yes it takes those two args. main character signature fr 🫶

---

🎀 ARGUMENTS 🎀

• bo — the buffer object you're wrapping a GTT ttm_tt object around. she's the one getting dressed up 💖
• page_flags — the page flags that get added to the ttm_tt object. little extra sparkle, except it's flags ✨

---

👑 DESCRIPTION 👑

so the description is short and iconic: this gets called by ttm_tt_create. that's it. that's the lore. 😭

side note, bestie: the page also points you at the source dir ./drivers/gpu/drm/amd/amdgpu if you wanna go read the real thing. go be nosy, it's encouraged 🙈

and that's the whole vibe check! sign-off time 🎀 this cutie came out of ./drivers/gpu/drm/amd/amdgpu and is dated October 2026 — mark your calendars, she's a future icon 💜🦋✨
