Hey there!
I've been trying to pass my GTX 1070 through to a Windows 10 VM via PCI Passthrough.
Specifications:
Motherboard: ASUS X99-E WS
CPU: i7 5820k
GPU1: GTX 760
GPU2: GTX 1070
The only component I'm unsure about being compatible with IOMMU is my motherboard, I've only one person claiming to be running a PCI passthrough setup on this motherboard and I haven't been able to locate their post again.
I followed the Arch wiki page on PCI passthrough (https://wiki.archlinux.org/index.php/PC … h_via_OVMF).
I started by check whether or not Intel Virtualization Technology was enabled in my UEFI, which it was.
I modified my /boot/loader/entries/arch.conf file to look likes this:
title Arch Linux
linux /vmlinuz-linux
initrd /intel-ucode.img
initrd /initramfs-linux.img
options root=PARTUUID=868e8296-68d4-40d2-9860-7827226f4475 rw quiet splash intel_iommu=on
dmesg|grep -e DMAR -e IOMMU
gave me this output:
[ 0.000000] DMAR: IOMMU enabled
Afterwards I ran the script provided below
#!/bin/bash
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##*/}"
done;
Which gave me no output, but I went on anyway.
[h1]Just including this part in case there is any relevant information to be found.[/h1]
I followed the vfio-pci method.
Output of
dmesg | grep -i vfio
[ 5.802933] VFIO - User Level meta-driver version: 0.3
[ 5.804991] vfio-pci: probe of 0000:06:00.0 failed with error -22

[ 5.805019] vfio_pci: add [10de:10f0[ffff:ffff]] class 0x000000/00000000
I cut this post short after being inexplicably not logged after hitting submit last time and losing the entire thing which cost me about 2 hours to fully write out .
Please let me know if I've left out anything relevant!
Any and all help would be appreciated!
EDIT: Forgot to mention my Google searches in this one.
I was searching on and off for a few days most of my search terms were a combination of: iommu; iommu groups; asus x99-e ws; systemd-boot; pci passthrough,
Despite looking through all the results that seemed even mildly relevant to my issues, I couldn't find any real solution.

Have you enabled vt-d in BIOS?
Intel Virtualization Technology isn't the same as vt-d, I had the same problem recently.

That was it! Thank you very much!
It was in Advanced -> System Agent, I thought they just clumped VT-x and VT-d together.

@FeelsBanjoMan - could you post your IOMMU groups and physical layout for your system? I'm looking into purchasing the same board and was curious how well the IOMMU groups are configured.
