💅 amdgpu_bo_create_user(9)

okay so bestie, welcome to the Kernel API Manual — yes that's the manual name, and yes this page is about amdgpu_bo_create_user. it's giving "one tiny function, whole lot of buffer object lore" ✨

🌸 NAME 🌸

amdgpu_bo_create_user — create an &amdgpu_bo_user buffer object 🎀

✨ SYNOPSIS ✨

int amdgpu_bo_create_user (struct amdgpu_device *adev , struct
amdgpu_bo_param *bp , struct amdgpu_bo_user **ubo_ptr );

like, three args, one int coming back at you. no cap, that's the whole signature 💅

🦋 ARGUMENTS 🦋

  • adev — the amdgpu device object. the actual GPU bestie we're doing all this for 🫶
  • bp — parameters to be used for the buffer object. this is the vibe spec, the whole blueprint honestly 📋
  • ubo_ptr — pointer to the buffer object pointer. yes, a pointer-to-a-pointer, she's double indirect and she's iconic 👑

💖 DESCRIPTION 💖

Create a BO to be used by user application; 🧚

that's it, that's the whole thing — the BO is for the user application to use, periodt. (also, tiny detail: the sentence ends with a semicolon in the original and honestly we respect the punctuation commitment 💀)

🔥 RETURN 🔥

0 for success or a negative error code on failure. so like, zero = slay, negative = 😭. check it, always.

ngl a negative return is your cue to actually handle the error. don't just vibe past it 🙈

alright bestie, that's the page 🎀 this one ships out of ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — so like, future-core of it all. go forth and allocate responsibly ✨💜
