Btw, "EFI_ACPI_ADDRESS_SPACE_DESCRIPTOR" is just a structure used across the codebase to represent an address space. It doesn't have anything to do with the ACPI tables if that was your impression. ACPI tables are only consumed by an OS. If you wish to have PCIe working there, you still have to manually declare your host bridges in DSDT/SSDT or use DynamicTablesPkg, as EDK2 does not automatically generate them for you. -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
