Your Linux kernel was compiled with IOMMU support, including DMA remapping. See the CONFIG_DMAR kernel compilation option. The PCI stub driver (CONFIG_PCI_STUB) is required as well. Your Linux kernel recognizes and uses the IOMMU unit.The default is the motherboard, BIOS and also actual PCIe layout. Updating to latest Kernel can remedy some weird IOMMU groupings however on most consumer/gaming motherboards IOMMU grouping is on no concern at all and can be done really badly. This is when you have to resort to manual overrides and creating your own groups.Reboot the system and hit DEL / Delete key to enter BIOS/EUFI setup: Ensure IOMMU is enabled, XHCI handoff is enabled, EHCI handoff is disabled, USB Legacy support is enabled. OS type I have set to Windows8 but I have CSM enabled "Compatibility Support Module" so Linux will boot via BIOS emulation instead of UEFI.Advanced users may wish to specify all system modules # in this array.

Pulled, thanks a lot Joerg!For BIOS part: AMD has removed IOMMU related registers. So there is no chance to let IOMMU work on our 890FX board unless AMD can provide such a process, and registers.
