STATUS_ACPI_ADDRESS_NOT_MAPPED
STATUS_ACPI_ADDRESS_NOT_MAPPED concerns the address-space side of ACPI processing. ACPI tables can describe access to system memory, I/O ports, PCI configuration space, embedded-controller space and other operation-region spaces. The requested address did not translate into an accessible target in the relevant ACPI context.
This is different from STATUS_ACPI_INVALID_REGION, which points to an invalid region declaration or reference, and from STATUS_ACPI_INVALID_ACCESS_SIZE, which concerns the size or bounds of a field access. Here the region may be known, but the address translation cannot establish an access target.
An ACPI address-space reference could not be translated
- Record the region space, base address, length, access direction and the AML method that initiated the access.
- Identify the relevant DSDT or SSDT declaration and any platform state that changes address availability.
- Correlate the failure with device enumeration, resume or hot-plug events that can change which address ranges are present.
