  • Sounds great I'm in hurry to try it. But my efforts to retrieve ACPI tables from an AsRock BIOS ROM (one that supports IOMMU) have been very limited, using UEFITool, MMTools, efiperun, and misc other tools. So if you have a AMD A55 chipset on a motherboard that support IOMMU, please send me a copy of your /sys/firmware/acpi/tables/DMAR (whatever the name is, if unsure ask me) anyway there is no risk for you. thanks!

  • I don't understand your answer: of course I can use Linux to retrieve data. Read again the question you'll see that know-how is not the problem. The problem is accessing some hardware with the right features. Commented Apr 12, 2019 at 13:24
  • @Eric, if hardware supports feature and it's not fused by firmware, OS can utilize it. VT-d is described in this document software.intel.com/sites/default/files/managed/c5/15/… Commented Apr 12, 2019 at 19:11
