The latest version (4.19.8-arch1-1-vfio) has build error due to patch:
drivers/pci/quirks.c:4617:28: error: ‘pci_acs_overrides’ undeclared here (not in a function); did you mean ‘pcie_acs_overrides’? { PCI_ANY_ID, PCI_ANY_ID, pci_acs_overrides }, ^~~~~~~~~~~~~~~~~ pcie_acs_overrides
I have pushed something that the patches apply, but I haven't tested the package itself.
whight: The vga arbiter patch does not apply in 4.19.x.
Applying: i915: Add module option to support VGA arbiter on HD devices (4.17)

You shouldn't have any troubles using the patch in your sources for 4.19.8. Built and tested it myself with linux from the core repo. If you'd like, I can help keep this maintained.
archqemu: I try to keep up to date with regards to whatever version is in [core]. The problem is, on version releases (e.g. 4.14 -> 4.15), I often have to rewrite the patches (this isn't normally a problem on patch releases like 4.16.7 -> 4.16.8). Because I'm both a full time student and work full time as a software engineer, I am sometimes unable to set aside enough time to update the patches and I get to it when I can. The semester is almost over at the time of this comment, so I should be able to set aside time for sure then, if not sooner.
okay cool, thanks for your quick reply!
I was just curious if there is any systematic release schedule related to the kernel releases.
archqemu: When it's done.
When can we expect an update of this package?
Awesome thanks markzz, I didn't know this, i'm still a bit of a noob (switched from debian) i'm going to try this for the next kernel update. Thanks again.

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
makepkgand searching the wiki/Arch forums is expected, and AUR helpers or Arch-based distros that are not Arch Linux are unsupported).
