I have H8DGU-F M/B, When booting kernel intel IGB driver says that there is not enought iommu resources.
WHet starting virtual machines another message "no DMAR table found" is showing so VMs cant use VT-d on onboard ETH cards.
DMAR table is defined for Intel VT-d only. In AMD platform, we have relative PCIe devices resource table called IVRS (See IOMMU spec http://support.amd.com/us/Processor_TechDocs/48882.pdf ).
http://www.acpi.info/spec.htm
AGESA code will read SBIOS defined MMIO address than scan all enumerated PCIe devices and build IVRS for ACPI OS. Linux bootloader has x86, AMD64, and Intel EM64T version. should install AMD64 on AMD Opteron platforms.
