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).

cinna: None of those functions in the call trace are in the patches that this kernel provide. I would either file a bug with Arch or with upstream.

I'm having a similar issue as zatricky where a VM refuses to launch when I have a dedicated gpu attached. Here's a relevant dmesg when I attempt to launch it. As for my hardware I'm running a Ryzen processor with a dedicated GPU for my host and another for my VMs

zatricky: Are you using an Intel iGPU for the host? Also, some relevant dmesg output would be helpful.

Latest package 4.15.1-1 resulted in sporadic errors from libvirtd when attempting to launch VM with dedicated GPU: Feb 08 22:08:04 <hostname> libvirtd[612]: 2018-02-08 20:08:04.406+0000: 612: error : virNetSocketReadWire:1808 : End of file while reading data: Input/output error</hostname>

Other VMs (not using GPU) were functional. From the moment I attempted to start the dedicated-GPU VM, virsh commands would no longer complete and virt-manager would become unresponsive.

Downgraded to 4.14.11-1 - all is working again.

Sorry about the lack of updates (if only I had unlimited time). I am currently building and testing 4.15 and you can expect it by this coming Friday.

EDIT: It is up and I need i915 users to tell me if everything's okay.

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.

abrilevskiy commented on 2017-12-06 06:26 (UTC)

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 ^_^

markzz commented on 2017-12-03 00:46 (UTC)

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