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).

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.

Kalinda: That is a patch that is irrelevant to what this package is doing. This package only fixes the specific issues related to ACS and Intel VGA arbitration along with general kernel bug fixes. This is not a catch-all patch set for all VM problems.

Hello, Would it be possible to get the new patch that fixes the NPT bug for the AMD folks included in this packages? It's here - https://patchwork.kernel.org/patch/10027525/ I and a few other people from the VFIO reddit/discord have tested it and it works amazingly well, we can finally game in our VMs now. I do have a PKGBUILD all lined for this and was going to submit it, but since we have this package it seems like it'd be better to just include the patch here. I'd be happy to test any future changes made to it to ensure they work. Thanks

Just an update, I've been not uploading new versions of this package due to a problem with USB devices. This problem should be fixed by a patch that I am testing right now. If it works, you'll see 4.13.9 uploaded today.

==> Starting package_linux-vfio-headers()... install: cannot stat 'Documentation/DocBook/Makefile': No such file or directory ==> ERROR: A failure occurred in package_linux-vfio-headers(). I have this same error.

I keep getting the following error when trying to build this package (both with pacaur and manually): ==> Starting package_linux-vfio-headers()... install: cannot stat 'Documentation/DocBook/Makefile': No such file or directory ==> ERROR: A failure occurred in package_linux-vfio-headers(). Aborting... It only appeared with the most recent update (afaik).
