• 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).

Zauberfisch: I"m honestly going to unpin that comment as it should be expected that people read the wiki and know how to use makepkg before trying to build any packages.

If someone will have similar problem there's bug link to follow: https://bugs.archlinux.org/task/66156 I temporary removed line make htmldocs and removed $pkgbase-docs from loop at the end of PKGBUILD so it compiles again.

I've very weird problem with compilation of this package:

Running Sphinx v3.0.0

@markzz: sorry. I wasn't actually asking, I know how to import a key or skip key checking. I just figured because there is a pinned comment for adding 2 of the 3 keys, it might be worth updating that message to include all 3 keys.

Not to dogpile, but I'd like to add "..or plug the error into google" :)

Zauberfish: Can you kindly read the wiki before being the 40,000th person to ask this?

I see the pinned comment saying I need to add 2 keys. But for me I still get an additional key error:

FAILED (unknown public key A5E9288C4FA415FA) ==> ERROR: One or more PGP signatures could not be verified!

seems the key for "Jan Alexander Steffens (heftig)" is also missing.

@giostark seems I have to dig deeper. After booting the default arch kernel, the problem continues to exist.

@PrfStrwberry- I have a 7700K and differ for two instruction from your: Intel® vPro™ Platform Eligibility and Intel® Trusted Execution Technology. And to me the mitigations seems to work. In general mitigation come activate host side but is not mandatory that the guest will use them. Those security mitigations are for you really necessary? Are you using those for networking VMs. Seems not bios options are available in Asus firmware. Kernel side I'm a noob so I can't say a thing. Thanks slowbro and markzz for your work. Me too I could not make my stuffs without this kernel.

Hey thanks for keeping this package up to date. I could not do anything without it. I am using an i7 8700k with an ASUS Maximus X CODE. I just have a small problem, after compiling and installing everything. When I create a VM inside virt-manager, I cannot enable and apply the box at enable cpu flaw mitigations. After clicking and applying, the tickbox goes blank again. Any tips?
