• 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).

Looks like recompiling this package did the trick for me.

I'm having problems with nvidia-dkms and this package:

==> dkms install nvidia/396.24 -k 4.17.3-1-vfio Error! Bad return status for module build on kernel: 4.17.3-1-vfio (x86_64) Consult /var/lib/dkms/nvidia/396.24/build/make.log for more information.

I'm not sure when the problems started happening, but it's probably started within the last week. Anyone else having issues with nvidia drivers failing to install for this kernel lately?

I'm trying to get operational again by trying combinations of different kernel and nvidia versions. Still no luck yet.

DocMAX: That line appears to be doing a job. Removing it would make me feel uneasy and without further information, I will not remove it.

You are free to do so when you build it though. The details of that reddit post also show that the person was using an Atom/Pentium/Celeron with a possible ACS cap and that line should absolutely not be removed.

If you want to discuss it with me further, I'd recommend turning to email and contacting me directly, especially if you have more information that will change my mind.

Could you remove the line described here?:

I'll add it soon then.

This patch was needed to enable ACS override on my machine using an i7-7260U

@Fleetscut ...damn TNX. Im a noob in linux so I was stuck thinking that was a nvidia problem. After the last gcc-8.1.0 I wasn't able to reinstall the nvidia-dkms module. By the way the virtual machine and the pci pass through worked fine, was only the host to have a 800x600 resolution ^_^ For the moment ill blacklist the new gcc.

i cant seem to build this kernel with gcc-8.1.0. i keep getting a message that mv cannot stat the temp directory that is being used to build. happens no matter where i point the build directory. i had to downgrade to my last version of gcc to get it to work.

When you build this PKGBUILD, you will get the three packages. As for how pacaur or ANY other aur helper works, I cannot say.
