----------------------------------------
29 March 2019. Summary of changes for version 20190329:
1) ACPICA kernel-resident subsystem:
Namespace support: Remove the address nodes from global list after method
termination. The global address list contains pointers to namespace nodes
that represent Operation Regions. This change properly removes Operation
Region namespace nodes that are declared dynamically during method
execution.
Linux: Use a different debug default than ACPICA. There was a divergence
between Linux and the ACPICA codebases. In order to resolve this
divergence, Linux now declares its own debug default in aclinux.h
Renamed some internal macros to improve code understanding and
maintenance. The macros below all operate on single 4-character ACPI
NameSegs, not generic strings (old -> new):
ACPI_NAME_SIZE -> ACPI_NAMESEG_SIZE
ACPI_COMPARE_NAME -> ACPI_COMPARE_NAMESEG
ACPI_MOVE_NAME -> ACPI_COPY_NAMESEG
Fix for missing comma in array declaration for the AcpiGbl_GenericNotify
table.
Test suite: Update makefiles, add PCC operation region support
2) iASL Compiler/Disassembler and Tools:
iASL: Implemented additional illegal forward reference detection. Now
detect and emit an error upon detection of a forward reference from a
Field to an Operation Region. This will fail at runtime if allowed to
pass the compiler.
AcpiExec: Add an address list check for dynamic Operation Regions. This
feature performs a sanity test for each node the global address list.
This is done in order to ensure that all dynamic operation regions are
properly removed from the global address list and no dangling pointers
are left behind.
Disassembler: Improved generation of resource pathnames. This change
improves the code that generates resource descriptor and resource tag
pathnames. The original code used a bunch of str* C library functions
that caused warnings on some compilers.
iASL: Removed some uses of strncpy and replaced with memmove. The strncpy
function can overwrite buffers if the calling code is not very careful.
In the case of generating a module/table header, use of memmove is a
better implementation.
3) Status of new features that have not been completed at this time:
iASL: Implementing an enhanced multiple file compilation into a single
namespace feature (Status): This feature will be released soon, and
allows multiple ASL files to be compiled into the same single namespace.
By doing so, any unresolved external declarations as well as duplicate
named object declarations can be detected during compilation (rather than
later during runtime). The following commands are examples that utilize
this feature:
iasl dsdt.asl ssdt.asl
iasl dsdt.asl ssdt1.asl ssdt2.asl
iasl dsdt.asl ssdt*.asl
ASL tutorial status: Feedback is being gathered internally and the
current plan is to publish this tutorial on the ACPICA website after a
final review by a tech writer.
