• 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).

Next weekend just finished and new linux major version came. Do you remember about us? ;)

Yeah, that's on me. I'll put it on my TODO list for this weekend.

Hello,

This package has been flagged out-of-date for some time... any news about updates?

Thanks a lot!

Just thought I'd add this in here For those looking to compile for 5.4.6.2:

Change pkgver in PKGBUILD

Replace add-acs-override.patch with updated one listed in a previous comment

Modify i915-vga-arbiter.patch as follows:

• For last diff, change all instances of intel_drv.h to display/intel_display.h

• Change 1457 to 432 (line numbers beneath above)

Finally update sha256 as needed in PKGBUILD

So if anyone needs a newer patch it's here https://gitlab.com/Queuecumber/linux-acs-override/raw/master/workspaces/5.4/acso.patch

jklc: https://git.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/linux

They are makedepends as well, you can remove them after building.

5.3.13(1ec4cb075348) wants the following additional dependencies:

why?

It was a mce Hardware Error. I have since installed rasdaemon and updated the intel microcode to the latest(0xae). 5.3.7.arch1-1 has been running smoothly for the past 18 hours.

jklc: I cannot confirm this issue. The kernel appears to be working fine on my machine. The only difference I can think of is I do not use an Intel iGPU on the host.
