STATUS_ACPI_INVALID_REGION
STATUS_ACPI_INVALID_REGION concerns the AML OperationRegion model. An operation region declares a named address-space window and fields are used to access it. This status means that the referenced region is not valid for the requested access or context; it is not simply a report of an unmapped physical address.
Compare the declaration, region space, scope and associated field with the access that failed. The ACPI specification defines multiple region spaces and imposes constraints on how particular regions and their fields are declared and used.
The referenced ACPI operation region was invalid
- Record the region name, region-space identifier, offset, length and declaring namespace scope.
- Verify that the associated field and access type are permitted for that region space.
- Distinguish this condition from
STATUS_ACPI_ADDRESS_NOT_MAPPED, where a known reference fails address translation.
