Just to clarify further. Are we allowed to access the memory allocated by our UEFI driver as RuntimeServiceData in our OS drivers (the physical address is passed by the uefi driver to controller and controller to OS driver)?

This works fine with normal cases, but will it work with IOMMU?. I see the IOMMU module in linux needs to know about the reserved regions through RMRR address table to map the access, does the GetMemoryMap supports this?
