Hi, I am doing Intel IOMMU emulation for q35. I need to add a DMAR table to ACPI. There is one field in the DMAR table called "Host Address Width", which indicates the maximum DMA physical addressability supported by this platform. I am not sure what this value should be and how to get this value. What is the best way to decide the value of HAW? Any suggestion is appreciated. :) Thanks very much!
