Hi folks,

I have some questions about ARM SBSA v3.0 and SBBR v1.0. Could anyone please provide the answers or some ideas?

1. In SBSA it says that I/O virtualization property should be expressed by

system firmware data. Then how to express this information by ACPI? Is only IORT table related? Or is there any examples?

Pass. Graeme?

Not sure I quite understood the question, but IORT is where the SMMUs are defined.
