amdgpu_vm_init(9)

💅 amdgpu_vm_init(9) — like, the Kernel API Manual page, bestie 🎀

okay so this is the amdgpu_vm_init(9) page from the Kernel API Manual, and honestly? it's a little one. a tiny icon. a snack. but we're gonna treat it with the respect it deserves because it's literally the moment a vm instance gets born ✨

---

🌸 NAME 🌸

amdgpu_vm_init — initialize a vm instance. that's it. that's the whole job. she's a starter, she's a setup girlie, she's giving "first day of school" energy 🎒

---

🦋 SYNOPSIS 🦋

int amdgpu_vm_init (struct amdgpu_device *adev , struct amdgpu_vm *vm ,
int32_t xcp_id );

like, three little inputs and one int back out. clean. minimal. obsessed 💅

---

💖 ARGUMENTS 💖

• adev — an amdgpu_device pointer. literally the GPU device itself, the main character of the whole file ngl 👑
• vm — the requested vm. this is the one you're initializing. she's the guest of honor 🫶
• xcp_id — GPU partition selection id, typed as int32_t. which partition are we talking about? this tells you. no cap 🔥

---

🌈 DESCRIPTION 🌈

Init vm fields. that's the whole description, bestie — she's short and she knows it 😭 the function goes in and sets up the fields on the vm you handed her, and that's the vibe check passed 🧚

---

⭐ RETURN ⭐

0 for success, error for failure. extremely straightforward, extremely correct, we love a binary outcome 🍓
