Pass Through an iGPU to Frigate from Proxmox

I am running Proxmox on a Dell Optiplex 7050 Mini with an i7-6700T. The i7-6700T has an integrated Intel 530 GPU and in order to use this GPU in Frigate for hardware acceleration it needs to be passed through from Proxmox.

Open the grub file

nano /etc/default/grub

Update the file

GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on iommu=pt"

Save and update

update-grub
reboot

Confirm IOMMU is enabled

dmesg | grep -e DMAR -e IOMMU

Blacklist Proxmox from using the iGPU

nano /etc/modprobe.d/blacklist-igpu.conf

blacklist i915
blacklist snd_hda_intel
options i915 enable_guc=0

update-initramfs -u
reboot

Enable PCIe passthrough for the iGPU

Get the PCI address of the VGA controller

lspci -nn | grep VGA

Bind the iGPU to the VFIO

nano /etc/modprobe.d/vfio.conf

options vfio-pci ids=8086:1912

update-initramfs -u
reboot

Pass the iGPU through to the VM

Install Intel iGPU drivers in Frigate VM

Check if iGPU is detected

lspci -nn | grep VGA

apt update
apt install -y intel-media-va-driver vainfo
vainfo
