amdgpu_vm_make_compute(9)

💅 amdgpu_vm_make_compute — the "glow-up your GFX VM into a compute VM" glow-up ✨

okay so this is page amdgpu_vm_make_compute(9) from the Kernel API Manual, and bestie, it's giving kernel-internals realness 🎀

---

🌸 NAME 🌸

amdgpu_vm_make_compute — Turn a GFX VM into a compute VM 🦋

---

✨ SYNOPSIS ✨

int amdgpu_vm_make_compute (struct amdgpu_device *adev , struct
amdgpu_vm *vm );

---

🎀 ARGUMENTS 🎀

• adev — an amdgpu_device pointer, aka the GPU's whole entire vibe 👑
• vm — the requested vm, like the one you want to ✨transform✨

---

💖 DESCRIPTION 💖

So here's the tea, and it's kind of a big deal: this only works on GFX VMs that don't have any BOs added and no page tables allocated yet 😭 Like, it has to be a fresh-faced VM with nothing going on — no cap, if you've already loaded it up, this is not the move.

What it actually does is change these VM parameters:

• use_cpu_for_update
• pte_supports_ats

Then it reinitializes the page directory so it reflects the changed ATS setting. slay 💅 That's it, that's the whole function, but it's lowkey doing important work.

---

🔥 RETURN 🔥

0 for success, -errno for errors. periodt 💀
