Looking at aarch64 it looks like the guest kernel doesn't use acpi but got a fdt somehow. Dunno how that happened. I guess ArmVirtPkg exports the FDT using EFI interfaces, then either the kernel gets it directly or grub is able to get and pass on the FDT. In any case it seems think the same should work for 32bit without too much trouble. cheers, Gerd
