Subject: Re: [PATCH 0/6] iommu/amd: enable ACPI hardware ID device support

Hi All,

Also, 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

Thanks,
Suravee
