I wish to pass it through to Ubuntu VM for plex transcoding. I am following this guide.
When I check
dmesg | grep -e DMAR -e IOMMU
Nothing shows up...Does that mean IOMMU is not enabled?

What am I doing wrong?

 

[MarkusF]

dmesg | grep -e DMAR -e IOMMU
Nothing shows up...Does that mean IOMMU is not enabled?

Yes it means either:

• IOMMU is not activated in your BIOS
• Your motherboard does not support IOMMU or needs a BIOS update
• You did not add intel_iommu=on iommu=pt to the kernel command line. Check it with cat /proc/cmdline

Thank you!

If wasn't enabled in the BIOS...
Had to disable all the HP junk like sure start etc.

I am getting the following error (console is not fully showing it but its i915 error??

Did you blacklist the i915 driver on the host? In your first post it says that the i915 driver is in use.
The host and the VM cannot use the same GPU at the same time.

ok, some progression!

Maybe try intel_iommu=igfx_off instead of intel_iommu=on

Please provide additional information if this does not resolve your issue:

• Which version of PVE are you using? pveversion -v
• Show the complete kernel command line with the kernel version: cat /proc/cmdline

I can passthrough to the ubuntu VM like this:


I can see the igpu inside the VM:

Then installed intel-gpu-tools
and it can't find it.
What else am I missing?

It seems like the driver is not loaded.

Can you try to install the intel gpu drivers in that VM?:

apt install xserver-xorg-video-intel mesa-utils

 

[fahadshery]

apt install xserver-xorg-video-intel mesa-utils

I installed it and now it shows this:

inxi -G &&  sudo dmesg | grep -i i915Graphics:
Graphics:
  Device-1: Intel CoffeeLake-S GT2 [UHD Graphics 630] driver: N/A
  Display: server: X.org v: 1.21.1.4 driver: gpu: N/A tty: 178x51
  Message: GL data unavailable in console. Try -G --display

driver is showing N/A but the Display showing new values.

and after loading the driver module into the kernel?:

modprobe i915

and after loading the driver module into the kernel?:

modprobe i915

Sorry but how do I load the the driver module into the kernel? is that in the VM or on Proxmox host?

both my proxmox host and VM shows nothing:

modprobe i915

there is no output of the following command within VM as well:

dmesg | grep i915

but on proxmox host I see this:

dmesg | grep i915

The intel driver i915 is blacklisted on your host, so you should not load the driver in that kernel.

modprobe returns nothing if the command was successful.

To unload the driver from the host run: modprobe -r i915

To load the driver into the VM kernel run modprobe i915 inside the VM.

Does inxi -G show that the driver is loaded?

What does your kernel cmdline look like for your VM?:
cat /proc/cmdline

ok I done that in the proxmox host

To load the driver into the VM kernel run modprobe i915 inside the VM.

I am getting this in the VM:
modprobe i915
modprobe: FATAL: Module i915 not found in directory /lib/modules/5.15.0-1051-kvm

Does inxi -G show that the driver is loaded?

still the same output in the VM:
inxi -G && sudo dmesg | grep -i i915Graphics:

cat /proc/cmdline

This is the output in the VM:
cat /proc/cmdline
