Intel NPU Driver / Passthrough

Hi,

I have an application that can make use of the NPU in the new Core Ultra series I have in my PVE host, the app will be running in Ubuntu and Intel have drivers ready to install on the VM.

I am not sure how to pass it through to the VM, it does not appear in the list of devices in the PCI mapping screen.

I think I might have to install the drivers on the host first? - it seems that you can get the apt packages from Intel if you sign up to their SDK programme: https://amrdocs.intel.com/docs/2.2/gsg_robot/install-npu-driver.html

Is there anyone else who has done this or would have any advice please?

Thanks

Oli

I never did passthrough with Intel, but it could be possible that with these newer gen GPUs you have to provide driver on the host that can split GPU into 2 or 4 "mediated devices". One of the mediated devices you would pick then for passthrough. This gives you acceleration inside VM, but no VGA output.

If you want VGA output from VM, you have to passthrough the whole device and no, with this you don't need a driver on the host.

Then you need to activate IOMMU + VT-d resp. AMD-Vi in BIOS.

Thank you.

Think it’s worth saying that although the concepts are similar, the NPU is not really a type of GPU? (At least, to the best of my knowledge) but it is on the chip and so I suppose similar approach applies. I do not need the VM’s to have VGA output etc, this is all for backend processing.

So when I look at mapping a PCI device by adding it, I do see a list of items in the drop down (raw device) list - including TB4 controllers etc, but I do not see anything that relates to the NPU.

I checked before installing and IOMMU etc were all enabled in the BIOS, I think the fact I can see some devices to map suggests pass through is working to some extent.

Doesn't really make a difference, GPU with or without physical VGA-connector inside VM is just some accelerator...opencl, vulkan, CUDA, tensorflow, pytorch...

I don't have experience with NPUs yet, it is possible they're bound to the GPU, even with split IOMMU-groups.

This is lspci from Ryzen 8600G, it should have NPU:

OK I have made some progress *I think* I worked out the PCI ID was 00:0b.0 and passed that through.

I can now see the PCI device within the VM, however after installing the driver within the VM I’m now getting this

(Sorry code option doesn’t work on iOS)

I can write up what I did to get this far, but just want to troubleshoot the rest of it first….
 
Mhm, maybe there is something more in BIOS that wants to be enabled. Is this path existent and does the file exist there? intel/vpu/vpu_37xx_v0.0.bin wherever that is.

OK So it's still not working but I have

1. Gone back into BIOS and check all IOMMU and VT etc settings, it's all showing as enabled and working

2. I've been through the PCI passthrough wiki page https://pve.proxmox.com/wiki/PCI_Passthrough#Verifying_IOMMU_parameters and the output from
Code: 
dmesg | grep -e DMAR -e IOMMU
shows
Code: 
DMAR-IR: Enabled IRQ remapping in x2apic mode
which makes sense, as I can also use
Code: 
pvesh get /nodes/pve1/hardware/pci --pci-class-blacklist ""
to list all the PCI devices.

These errors are similar if you passthrough a GPU without its audio device.

For example my NVIDIA, it needs both devices to work regardless if you need the audio part:
Code: 
01:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1)
01:00.1 Audio device: NVIDIA Corporation GP107GL High Definition Audio Controller (rev a1)

Bildschirmfoto zu 2025-02-19 19-31-23.png
= 01:00.0 + 01:00.1

So just a guess, but maybe you need these together:
Code: 
00:0a.0 Signal processing controller: Intel Corporation Device ad0d (rev 01)
00:0b.0 Processing accelerators: Intel Corporation Arrow Lake NPU (rev 01)

Or just 00:0b.0 + "All functions" deactivated.

I am having pretty much the exact same issue. Only difference is I can get it working on the host, but receiving the same "Failed to boot the firmware: -110" inside the guest VM (Ubuntu 24). I've tried seemingly everything and hoping someone else might have figured this out.

ASUS NUC 14 Pro AI (Core Ultra 7, Meteor Lake)

Host:

Bash: 
root@proxmox:~# uname -a
Linux proxmox 6.8.12-8-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.12-8 (2025-01-24T12:32Z) x86_64 GNU/Linux

Added options to the vfio.conf (8086:7d1d is the vendor:device ID found from the recognized NPU)

Bash: 
root@proxmox:~# cat /etc/modprobe.d/vfio.conf
options vfio-pci ids=8086:7d1d

Added vfio to modules file

Bash: 
root@proxmox:~# cat /etc/modules
vfio
vfio_iommu_type1
vfio_pci
vfio_virqfd

Added intel_iommu=on and tried both with and without iommu=pt to /etc/default/grub

Bash: 
root@proxmox:~# cat /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"
(truncated)

When I detach the PCI device from the VM and reboot, /dev/accel/accel0 is visible to the Proxmox host.

So just a guess, but maybe you need these together:
Code: 
00:0a.0 Signal processing controller: Intel Corporation Device ad0d (rev 01)
00:0b.0 Processing accelerators: Intel Corporation Arrow Lake NPU (rev 01)

Or just 00:0b.0 + "All functions" deactivated.

I realize I'm on Meteor Lake, but I tried this as well and no luck.

This feels like a driver bug to me but it's possible I'm doing something wrong. Any assistance would be much appreciated - thanks in advance.
