A Quick Solution for conventional H/W IP in the modern ARM based SoC; Modern ARM based SoCs have wider address bus than conventional 32bit address space. However, in such SoC, there are some conventional H/W IP which able to access only 32bit physical address space. An IOMMU frameworks are proposed to Kernel Community to manipulate dynamic address translation for conventional H/W IPs. And also, there are needs to use static address offset to fit those conventional H/W IPs into over 32bit address space. In this presentation, it mentioned how to merge dynamic IOMMU manipulation and static address offset scheme as the Quick Solutions.
