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).

@daniel_shub I've added a default value for the empty variable. Will revise to remove git command with a later revision... need to find another way to list tags.

@xiota I am still having issues.

The warning about git is not that surprising since it happens before the dependencies are installed. Maybe not having git at that point is an issue, but if I run the grep on line 96:

_dl_url_arch='https://gitlab.archlinux.org/archlinux/packaging/packages/linux' pkgver=6.13.7 git ls-remote "$_dl_url_arch.git" | grep -Eo "v${pkgver}-arch[0-9]+" | sort -rV | head -1

I do not get any output which leads to the likely incorrect linux-.patch.zst source file. This makes me think there is something wrong with "v${pkgver}-arch[0-9]+"

Sorry for the edits, it is like I am going nuts. It does not build in a clean chroot. I think it has to do with the change to _srctag and the grep on line 96.

I don't know if anything can be done about IOMMU shared with other devices. Maybe someone else knows more?

Joeythe_fish commented on 2024-09-19 04:11 (UTC)

Yes it is, but the 1050 TI is still reading as attached to group 14, which contains a bunch of things, including both network devices.

xiota commented on 2024-09-19 04:06 (UTC)

Isn't this what you want, VGA devices on separate IOMMU groups?

IOMMU Group 14 06:00.0 VGA compatible controller [0300]: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] [10de:1c82] (rev a1)
IOMMU Group 15 07:00.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Ellesmere [Radeon RX 470/480/570/570X/580/580X/590] [1002:67df] (rev ef)

Hello, again. Thanks for the update. I'm having an issue where I apply the patch, but it's not splitting up the iommu groups like I expected, or at least like happened when I last used the patch on my old PC. I'm trying to run my Nvidia 1050TI on a VM, but it is still a member of a larger group. https://pastebin.com/yfGY5jE8 I'm not sure what I'm doing wrong. This is what my GRUB file looks like currently. GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 amd_iommu=on ,multifunction video=efifb:off video=vesa:off vfio-pci.ids=10de:1c82,10de:0fb9 pcie_acs_override=downstream">

@Joeythe_fish

Sorry if my answer is incomplete GPU: AMD ATI Radeon RX 6600/6600 XT/6600M GPU: NVIDIA GeForce RTX 3070 (in a pcie slot but no monitors plugged into it) Arch Linux x86_64, Kernel 6.9.10-arch1-1 I use Awesome DE

When it 'crashes', my terminal (and all monitors) stops updating and it just restarts. No error messages. Nothing shows on screen. I don't notice the fans getting louder.

Thanks everyone for the responses!
