27 April 2018. Summary of changes for version 20180427:

This release is available at https://acpica.org/downloads


1) ACPICA kernel-resident subsystem:

Debugger: Added support for Package objects in the "Test Objects" command. This command walks the entire namespace and evaluates all named data objects (Integers, Strings, Buffers, and now Packages).

Improved error messages for the namespace root node. Originally, the root was referred to by the confusing string "\___". This has been replaced by "Namespace Root" for clarification.

Fixed a potential infinite loop in the AcpiRsDumpByteList function. Colin Ian King <colin.king(a)canonical.com>.


2) iASL Compiler/Disassembler and Tools:

iASL: Implemented support to detect and flag illegal forward references. For compatibility with other ACPI implementations, these references are now illegal at the root level of the DSDT or SSDTs. Forward references have always been illegal within control methods. This change should not affect existing ASL/AML code because of the fact that these references have always been illegal in the other ACPI implementation.

iASL: Added error messages for the case where a table OEM ID and OEM TABLE ID strings are longer than the ACPI-defined length. Previously, these strings were simply silently truncated.

iASL: Enhanced the -tc option (which creates an AML hex file in C, suitable for import into a firmware project):
  1) Create a unique name for the table, to simplify use of multiple SSDTs.
  2) Add a protection #ifdef in the file, similar to a .h header file.

AcpiExec: Added a new option, -df, to disable the local fault handler. This is useful during debugging, where it may be desired to drop into a debugger on a fault.
