Hello, I've noticed that this has been out of date for a while - I've updated the package to sync with the latest Arch vanilla kernel.
The ACS patch was successfully tested on a Gigabyte X570-UD, by passing through a chipset USB controller.
The i915 patch needed minor refactoring to build on 5.14, however I don't have any Intel hardware, so I am unable to test this patch.
Here's the link to my tree for 5.14.2-arch1-2: https://github.com/hurrian/linux-vfio/tree/5.14.2-arch1-2-vfio . I've also submitted this as a PR to @slowbro's repository.
Edit: The update to 5.14.2 has been merged.

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).
