• 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).

Yeah, turns out, maintaining this package is not always just updating the version number and grabbing a new config. I'll work on an updated patch today.

Applying the patch is broken right now:

I strongly suggest rebuilding this after updating openssl to 3.0.7 (or better, building in a clean chroot which has an updated openssl), as this may break things otherwise.

Same problem here - I can't get 6.0.5 to boot, it hangs as soon as it gets to the framebuffer.

6.0.2.arch1-1 is causing weird issues for me. The initial framebuffer seems to be broken (I am not using quiet), but when the xorg or wayland session starts it works fine. Trying to troubleshoot this I only found out it happens when I specify ids with vfio-pci.ids as a kernel parameter.

The symtoms are extremly similar to this post https://bbs.archlinux.org/viewtopic.php?id=280512.

The package has been out of date for a while now. Is the package definitely stopped? Can we expect an update soon? Is there any other solution than to do all the hand :( In any case, thank you for your time and skills.

Has anyone tried the Manjaro kernel with the ACS patch on Arch Linux? (linux-acs-manjaro)

Maybe a tip for other noobs like me. Now the system update work with the gcc 12.1. Installing the pre-compiled kernel (done with gcc 11.2) or via helper (yay always search for gcc 11.2) result in error with the latest nvidia modules (that use the gcc 12.1). Solutions: 1) downgrade the gcc to the 11.2 (bleah solution) 2) (better solution) compile the kernel from the source without helpers using: makepkg -Crso Then: makepkg -ers Then: sudo pacman -U (3 packs generated before) Here the topic of the issue: https://bbs.archlinux.org/viewtopic.php?pid=2039309#p2039309

pssst, this version is 2 patches old now

HI, I'm unable to completely update my Manjaro for two update cycles now. These three are the last stragglers: linux-vfio, linux-vfio-docs, linux-vfio-headers.

This is all I get from pacman (gui) before update terminates:

  Preparing...
  Cloning linux-vfio build files...
  Generating linux-vfio-docs information...
  Failed to prepare transaction:
  Failed to generate linux-vfio-docs information

Any advice?
