amdgpu_vm_handle_moved(9)

💜 amdgpu_vm_handle_moved(9) — Kernel API Manual, bestie edition ✨

Okay so picture this: you're deep in the kernel, the manual is literally called amdgpu_vm_handle_moved(9), and it's about making sure the BOs that got moved actually show up correctly in the PTs. That's the whole vibe. Let's go 🫶

---

🌸 NAME 🌸

amdgpu_vm_handle_moved — handle moved BOs in the PT

---

🎀 SYNOPSIS 🎀

int amdgpu_vm_handle_moved (struct amdgpu_device *adev , struct
       amdgpu_vm *vm , struct ww_acquire_ctx *ticket );

---

🦋 ARGUMENTS 🦋

• adev — the amdgpu_device pointer, your classic device handle, iconic 💅
• vm — the vm you're asking for, the requested vm
• ticket — an optional reservation ticket used to reserve the VM

---

✨ DESCRIPTION ✨

So what does it actually do? It makes sure all BOs which are moved are updated in the PTs. Every single one. No cap.

🚨 PTs have to be reserved! Like, this is not a suggestion, bestie — that's a hard requirement. Reserved PTs or nothing.

---

🔥 RETURN 🔥

0 for success. That's it. That's the whole return section. Slay 🌈
