I believe you meant here the niche of the (x86) platforms that are not ACPI-enabled. By default 99% of the x86 platforms are ACPI enabled with the exceptions: - Intel MID (2010-2015, SFI based, enabled in U-Boot) - Tunnel Creek (2010, DT based) - A few SpreadTrum SoCs (2017, DT based) > but I don't know whether it was set up on ARM or not.
