2015-09-27 Thread Gabriel L. Somlo
Add a fw_cfg device node to the ACPI SSDT, on machine types pc-*-2.5 and up. While the guest-side BIOS can't utilize this information (since it has to access the hard-coded fw_cfg device to extract ACPI tables to begin with), having fw_cfg listed in ACPI will help the guest kernel keep a more
