Hello,
the ACPI specification defines OpRegions for ACPI bytecode to interact with devices, one suche device being the Embedded Controller. After looking at some example ACPI tables, it seems that Embedded Controller OpRegions can be defined anywhere inside the ACPI namespace, and not just inside the Embeeded Controller device scope.
What is the Windows kernel policy for such OpRegions? Which Embedded Controller will be used to handle them (if any)?
Thanks,
Armin Wolf
