WebJun 14, 2024 · The passthrough capability itself requires hardware that supports intel VT-d or AMD-vi. This capability can be reported through reading /sys/class/iommu and looking for ‘dmar’ file. Iommu also needs to be allowed on the host, which can unreliably be detected by parsing /proc/cmdline for intel_iommu=on or iommu=on. WebCheck your iommu groups to see what else is in the same group as the USB card. If you can't pass all of those devices through, try another PCIe slot. If that still doesn't work, you can try applying the ACS patch to force separate iommu groups. You can even post your iommu groups here for validation that that is, in fact, the issue.
