• 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).

Thanks for the kernel, it worked like a charm :)

Changing this from a help, to a informational. After installing this kernel and headers I could boot but lightdm and even SDDM would not start. What I found was an error in Xorg.0.log about no module found for my NVIDIA driver. I am on Antergos so I just re-installed all my drivers, which alone did not help. I reinstalled the NVIDIA DKMS sudo pacman -S nvidia-dkms This will vary based on how you installed your drivers.

I see, thanks for the info. The tricky part seems to be the recompilation of the custom kernel to change configs (in order to enhance gaming experience) Hopefully i will manager to build the kernel of my need from your git source

You can disable the patch if you want by commenting out the appropriate patch line in the prepare() function of the PKGBUILD file, but it's not really necessary. The patch does nothing unless you provide the required kernel command line arg. If you want to use the patches on another kernel, that is also pretty simple. Compare this PKGBUILD to the main Arch "linux" package and you'll see that I had to make very minimal changes. Mainly, you need to add the patches to the source array, the patch checksums to the sha256sums array, and then actually apply the patches by calling the patch command from the prepare function. You might also want to change the "pkgbase" variable at the top so you can install both kernels at the same time.

Hi, since i don't need the i915 patch (using ovmf) can i remove it through the pkgbuild or something? Also, is it possible to use an already customed kernel for this? I'm looking for ck kernel optimized for my cpu : https://wiki.archlinux.org/index.php/Repo-ck

retested today and all works fine again

Have you tried 4.4-4? If you still have problems, try the plain arch 4.4-4 from the testing repo. If the problem still exists there, file a bug against the main arch package.

After updating to 4.4-3 it no longer detects my nvme ssd during boot

Updated with the 2 patches for arch testing 4.4-4 plus a patch to fix CVE-2016-0728.
