Isaku Yamahata 6be8cf56bc acpi/core: always set SCI_EN when SMM isn't supported ... If SMM is not supported, ACPI fixed hardware doesn't support legacy-mode. ACPI-only platform. Where SCI_EN in PM1_CNT register is always set. The bit tells OS legacy mode(SCI_EN cleared) or ACPI mode(SCI_EN set). With the next patch (setting fadt.smi_cmd = 0 when smm isn't enabled), guest Linux tries to switch to ACPI mode, finds smi_cmd = 0, and then fails to initialize acpi subsystem. This patch proactively fixes it. This patch changes guest ABI. To keep compatibility, use "smm-compat" introduced by earlier patch. If the property is true, disable new behavior.
