https://wiki.archlinux.org/title/PCI_passthrough_via_OVMF#Bypassing_the_IOMMU_groups_(ACS_override_patch) Basically this is a feature of the zen kernel, since manjaro didn't add this zen kernel feature and there is no zen kernel in the software source, I had to compile the AUR package linux-jcore, so hopefully the manjaro kernel can restore this zen kernel feature. https://aur.archlinux.org/packages/linux-jcore Basically this package just integrates the 0999-acs.gitpatch patch for the manjaro kernel, I think it should be very easy to integrate this patch into the manjaro kernel.
