Leaving eclairvoyant's comment pinned because it contains some useful information.
Patch policy is different, but similar.
- Primary purpose of this package are the ACS override and i915 VGA arbiter patches.
- Upstream Arch patches will be applied to maintain parity with the standard kernel.
- No other patches will be added.
Package does have options that can be changed, like building with clang or disabling Arch patches.
- Defaults will match Arch packages, except when incompatible with this package's primary patches.
- Options are subject to change. Read PKGBUILD for details.
Avoid commenting and flagging at the same time for the same issue.
- Flag for common issues with standard solutions, like new releases, key changes, etc.
- Comment for issues requiring explanation or debugging.
  - Use a pastebin for blocks of text more than a few lines.

This package exists for the specific purpose of adding ported patches based on those originally created by Alex Williamson for:

Bypassing the default IOMMU grouping by overriding PCIe ACS support, and
Enabling VGA arbitration support on Intel iGPUs.

Arbitrary patches will not be added.

Refer to the wiki on PCI passthrough and this blog post on IOMMU groups for risks/caveats before using this package.

Regular AUR etiquette applies as well (knowledge of makepkg and searching the wiki/Arch forums is expected, and AUR helpers or Arch-based distros that are not Arch Linux are unsupported).

@dominicm what kernel params are you using? I have: "intel_iommu=on pcie_acs_override=downstream" and each of my devices is in separate IOMMU group

dominicm commented on 2016-09-30 15:22 (UTC)

@Myd Updating to 4.7.4-1 seems to have fixed it, I don't think I changed anything else. The group is still not clean as I have 3 other devices in it but I am able to passthrough anyways. IOMMU worked just fine before it was just this one device.

Myd commented on 2016-09-29 19:37 (UTC)

@dominicm I just updated to 4.7.4 and IOMMU groups look fine, you can check with "dmesg | grep -i IOMMU"

dominicm commented on 2016-09-04 17:57 (UTC)

Has anyone had issues with pci grouping after updating to 4.7.2 (from 4.5)? An integrated audio card can no longer be passed through due to the IOMMU group being nonviable where it was before. Is there a way to verify acs patch is actually active/applied?

Thanks for letting me know. I found that nvidia-dkms was sufficient, as well.

s0ul commented on 2016-07-21 02:30 (UTC)

Installing nvidia-dkms is sufficient, you don't need nvidia driver installed with it.

erylflynn commented on 2016-07-21 01:57 (UTC)

batarjal, that is what I did at the time to resolve it. But it looks like things have been packaged differently for Antergos drivers. Below are what I have installed. I suspect you can drop the nvidia and just install nvidia-dkms and nvidia-utils now. Below are the nvidia packages I have installed and working. extra/libvdpau 1.1.1-2 [installed] extra/libxnvctrl 367.35-1 [installed] extra/nvidia-dkms 367.35-1 [installed] extra/nvidia-libgl 367.35-1 [installed] extra/nvidia-settings 367.35-1 [installed] extra/nvidia-utils 367.35-1 [installed] multilib/lib32-libvdpau 1.1.1-2 [installed] multilib/lib32-nvidia-libgl 367.35-1 [installed] multilib/lib32-nvidia-utils 367.35-1 [installed]

erylflynn: I'm on antergos, as well, and when I try to run "sudo pacman -S nvidia nvidia-utils nvidia-dkms", I receive an error stating that nvidia and nvidia-dkms are in conflict. Is there a typo in the command you used?
