  • 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:

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).

Hiya, how can I use this kernel on Manjaro Linux? ty

markzz commented on 2017-12-14 06:10 (UTC)

(4.14.5+) Because Arch itself has dropped i686 support, I have removed i686 from the PKGBUILD and there is no config file either.

I use Nvidia cards and Intel hardware and in order to get it working - ACS patch is required. Therefore AGESA update will not eliminate for ACS.

mynameisrar commented on 2017-12-05 17:29 (UTC)

The NPT patch is included in the kernel as of 4.13.3 for you AMD people. When the upcoming AGESA update releases we probably won't even need this ACS patch anymore either ^_^

Almost always a minor release causes the patches to need to be rewritten. I'll be getting on this soon.

Any news about 4.14? I tried to apply i915-vga-arbiter.patch to linux-drm-tip-git without success :(

markzz commented on 2017-11-27 02:42 (UTC)

marandus: WHOOPS! Thanks for catching that. I will fix. timofonic: If you require the features the patches provide, yes, the patches will be required for 4.14. I will not update this PKGBUILD until linux 4.14 is released in core. fantacinni: That patch is not what this PKGBUILD is trying to do. If you need/want that patch in the kernel you build for your system, you can add it yourself. I don't think it's necessary to turn this PKGBUILD into the catch-all VM set.

Patch request Would you add the AMD SVM performance fix patch? https://level1techs.com/article/patch-npt-ryzen-better-performance Thanks!

4.14 available. Are patches still required in 4.14.x?

marandus commented on 2017-11-25 20:21 (UTC)

Is there any specific reason why the add-acs-overrides.patch contains in line 121 a check for a semicolon if (*p != ';') { instead of a colon? if (*p != ':') { The semicolon check prevents single ID ACS overrides to be possible, always fails with error message "PCIe ACS invalid ID". The patch you find via google has a colon check there, which is actually the only check that makes sense at that line.
