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).

Dehir: What?

Dehir commented on 2018-04-06 15:18 (UTC)

IF there is every possible to get realtime kernel with vfio same time :P

markzz commented on 2018-03-08 21:25 (UTC)

If either of you can get a core dump, I can investigate, but I don't know what else to tell you because I do not have the same hardware as you.

I can also confirm that with 4.11.4+ I cannot start my VMs that have a dedicated GPU. Experiencing output very similar to @cinna .

markzz commented on 2018-02-10 01:51 (UTC)

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.
