Tsirkin" , Igor Mammedov , Marcel Apfelbaum , Paolo Bonzini , Richard Henderson , Eduardo Habkost All PC machine type derivatives will use the same ACPI table build methods. But with that change in place, any new x86 machine type will be able to re-use the acpi-build API and customize part of it by defining its own ACPI table build methods. Cc: "Michael S.
