From: Wan Zongshun <vincent....@amd.com> There are some devices indentified using ACPI HID format in AMD chip. This patch series enable iommu support for those ACPI HID device, since the existing AMD iommu only supports PCI bus based device.
The latest public version of AMD IOMMU specification that describes the support for IVHD type 40h and ACPI HID IVHD device type, implemented by this patch series, is available here: http://support.amd.com/TechDocs/48882_IOMMU.pdf The V2 adds two new patches: patch 5 and patch 8 according to Joerg's comments. There is a little modification in patch 6 to distinguish pci and none pci.
