ACPI was initially enabled on BayTrail based boards. Testing was done by booting
a pre-installed Ubuntu 14.04 from a SATA drive. Installing Ubuntu 14.04 and
Windows 8.1/10 to a SATA drive and booting from there is also tested. Most
devices seem to work correctly and the board can respond a reboot/shutdown
command from the OS.
For other platform boards, ACPI support status can be checked by examining their
board defconfig files to see if CONFIG_GENERATE_ACPI_TABLE is set to y.
