(CANCELLED) PCI Passthrough - Razer Blade 14

I recently bought a Razer Blade 14. My hope is to be able to play the 3-4 hold out games I need Windows for on my Arch Linux install (looking at you Blizzard!) without dual-booting. The specs are:

Memory 15,6Gib
Processor Intel Core i7-7700HQ CPU@2.80GHz x8
Graphics Intel HD Graphics 630 (Kaby Lake GT2)
OS name Arch Linux
OS type 64-bit
Disk 511.8 GB

NVIDIA Corporation GP106M [GeForce GTX 1060 Mobile 3GB]

I have been following the instructions here: … requisites

The BIOS shows VT-d as enabled (and I have been able to run VMs with virt-manager. I also get output from the instructed dmesg command:

$ sudo dmesg | grep -e DMAR -e IOMMU

However, the first hurdle I come to, is an apparent lack of IOMMU groups being defined?

shopt -s nullglob
for d in /sys/kernel/iommu_groups/*/devices/*; do
    n=${d#*/iommu_groups/*}; n=${n%%/*}
    printf 'IOMMU Group %s ' "$n"
    lspci -nns "${d##*/}"
$ ./

The script returns nothing. This is the first hurdle on this path to no more dual-booting, and I didn't make it very far. I am stumped even after working with Google on this off and on the past week.

Thank you in advance for your assistance!
