Looking at Documentation/arm64/acpi_object_usage.txt in Linux kernel, it
says
"
DBG2 Signature Reserved (signature == "DBG2")
== DeBuG port table 2 ==
Microsoft only table, will not be supported.
"
It seems that Linux kernel doesn't support or need it, but Windows
requires it. So does it need to test this on Windows?
