I meant DT or ACPI on ARM, actually. I don't know what the x86 approach is for fw_cfg but I think it's just "known address". (For ARM we don't I think currently expose fw_cfg in the ACPI tables, but we probably ought to; only needed for the edge case where you actually wanted to read fw_cfg in the guest kernel rather than just the guest firmware, though.) thanks -- PMM
