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).

Really nice, Dan. Appreciate your effort in packaging that. Currently trying it out. :)

I just put together linux-vfio-lts which is currently just a copy of linux-vfio-4.1.6 with a different name: https://aur.archlinux.org/packages/linux-vfio-lts That will let you install both at once. I'm working on getting that upgraded to 4.1.9 soon, assuming it doesn't break anything for me. I have the hd 7850 for the host and an r9 280x for the vm and those both end up in the same iommu group without the acs patch. I'm pretty sure my 7850 isn't supposed to be supported by the amdgpu driver, so that shouldn't be the problem. Don't think the 280x is supported either.

My motherboard is an ASRock Z87 Extreme6. If I only attach a GTX 980 and a Renesas USB 3.0 card, I do not need to enable the ACS Override patch. But since I attach IBM M1015 card but for the host (not assigning the vfio-pci driver), I have to enable the ACS Override patch. If I recall correctly the IOMMU groups have the same grouping as it used to in 4.1.6. Last night I just downgraded back to 4.1.6 using your link, thanks! Is there any way in Arch AUR to install both version of the same kernel edition (linux-vfio-4.1.6 and linux-vfio-4.2.1) so I can just switch on GRUB menu? Does your HD Radeon issue is because of the new amdgpu driver on 4.2?

I am using OVFM also. My vm gets 6 cores and 8 GB memory, and I also require the acs override for my motherboard (asrock z77 extreme 6). Are you also using acs override? Maybe the patch isn't working properly anymore. But I also had other problems with this 4.2.1 kernel. I have a hd 7850 for my host gpu with a triple monitor setup. A big 1440p in the middle and two rotated 1080p on either side. As soon as I would log into gnome, the main 1440p screen would just shut off.

Yup, my setup also broken with this update. Though I found a workaround after seeing this ticket [1]. In kernel 4.1.6, I always had 8 vcpus with 16 GB of memory, but in 4.2.1 I need to decrease the settings to just 4 vcpus with 8 GB of memory. Seems related to [2] and [3], which told us that the miscoding looks like on the OVMF side. Do you happen to also use OVMF? Meanwhile, I'm struggling to downgrade to 4.1.6 until this issue has resolved. :) [1] https://github.com/tianocore/edk2/issues/21 [2] https://www.redhat.com/archives/vfio-users/2015-September/msg00395.html [3] http://thread.gmane.org/gmane.linux.kernel/1952205/focus=1996025

So, I've upgraded this to 4.2.1, but it has completely broken gpu passthrough for me, among various other things, so I can't say I recommend actually upgrading to this. I am open to any suggestions as to how to fix this. If you need an older version, click the "view changes" link above. 4.1.6 is the last version that works for me, which you can download here: https://aur.archlinux.org/cgit/aur.git/snapshot/aur-5edfba302fe2307a9e1920d5b30324e3d5147ade.tar.gz

wwwkeys.de.pgp.net didn't seem to work for me. Instead pool.sks-keyservers.net seems to be up. gpg --keyserver pool.sks-keyservers.net --recv-keys 79BE3E4300411886 gpg --keyserver pool.sks-keyservers.net --recv-keys 38DBBDC86092693E
