amdgpu_vm_prt_fini(9)

💅 amdgpu_vm_prt_fini(9)

okay so bestie, welcome to the Kernel API Manual ✨ — today's main character is amdgpu_vm_prt_fini(9), and honestly she's a lil goodbye girl 🎀

---

✨ NAME ✨

amdgpu_vm_prt_fini — finish all prt mappings 🦋

like, all of them. every last one. closing time, girlies 🌸

---

🌈 SYNOPSIS 🌈

void amdgpu_vm_prt_fini (struct amdgpu_device *adev , struct amdgpu_vm
*vm );

no return value, because she doesn't need to report back — she just does it 💅

---

🫶 ARGUMENTS 🫶

• adev — amdgpu_device pointer 👑 your lil handle to the device, the passport she needs to get anything done
• vm — requested vm 💖 the virtual memory she's about to tidy up, specifically requested, no guessing

---

💜 DESCRIPTION 💜

Register a cleanup callback to disable PRT support after VM dies 🪦✨

that's it, that's the whole vibe. she doesn't rip things apart herself — she registers a callback so that when the VM eventually passes away, PRT support gets switched off on the way out. booking the cleanup crew in advance, iykyk 🧚
