AcpiCodec module: (Warning: acpi signature not implemented)␊
------------------␊
IMPORTANT NOTE: 1- with AcpiCodec all aml files must be placed in /Extra/Acpi/, alternate or overridden path is no longer supported␊
␊
2- the name of the aml file(s) is not important anymore but it must contain the extention .aml, for example let suppose that you have 3 aml files: dsdt.aml, ssdt-0.aml and ssdt-1.aml␊
you can rename your dsdt file into blablabr.aml, and rename your ssdt files into blablablaen.aml and blablablablada.aml, acpicodec will auto-magically detect those files as 2 ssdt and one dsdt␊
