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).

@meshedpotato, you can simply edit the 'config' file in the tar.gz you download from AUR. If you're currently using an AUR helper to install (i.e. yay) you would have to abandon that in favor of manually building it. There's plenty of docs on the wiki about how to build an AUR package, so I'll skip the details; but for your specific situation, you'd:

Edit the 'config' file and change whatever parameters you want
run sha256sum config and replace the value in the PKGBUILD
build the package

Best of luck!

Hi Folks, any pointers on how i would be able to build with CONFIG_PREEMPT_VOLUNTARY=yes, the ACS patch has sorted out my IOMMU groups but I have large boot times.

I think I'm facing https://forums.unraid.net/topic/72172-unraid-os-version-653-available/

not sure where to start, Thank!

the sphinx issue will be worked-around in 5.6.3, from upstream: link. building/testing now.

JuniorJPDJ: For the sphinx issue, another "fix" is to install python-sphinx-1 also fixes the issue, but might break other dependency so it is up to you which solution you chose. (It is an alternate dependency on the docs package)

Zauberfisch: I"m honestly going to unpin that comment as it should be expected that people read the wiki and know how to use makepkg before trying to build any packages.

JuniorJPDJ commented on 2020-04-08 14:01 (UTC)

If someone will have similar problem there's bug link to follow: https://bugs.archlinux.org/task/66156 I temporary removed line make htmldocs and removed $pkgbase-docs from loop at the end of PKGBUILD so it compiles again.

JuniorJPDJ commented on 2020-04-08 13:51 (UTC)

I've very weird problem with compilation of this package:

Running Sphinx v3.0.0                                                                                                 

Extension error:                                                                                                      
Could not import extension cdomain (exception: cannot import name 'c_funcptr_sig_re' from 'sphinx.domains.c' (/usr/lib/python3.8/site-packages/sphinx/domains/c.py))

@markzz: sorry. I wasn't actually asking, I know how to import a key or skip key checking. I just figured because there is a pinned comment for adding 2 of the 3 keys, it might be worth updating that message to include all 3 keys.

Not to dogpile, but I'd like to add "..or plug the error into google" :)

Zauberfish: Can you kindly read the wiki before being the 40,000th person to ask this?
