Summary of changes for version 20200717: + +This release is available at https://acpica.org/downloads + + +1) ACPICA kernel-resident subsystem: + +Do not increment OperationRegion reference counts for field units. Recent +server firmware has revealed that this reference count can overflow on +large servers that declare many field units (thousands) under the same +OperationRegion. This occurs because each field unit declaration will add +a reference count to the source OperationRegion. This release solves the +reference count overflow for OperationRegion objects by preventing +fieldUnits from incrementing their parent OperationRegion's reference +count. + +Replaced one-element arrays with flexible-arrays, which were introduced +in C99. + +Restored the readme file containing the directions for generation of +ACPICA from source on MSVC 2017. Updated the file for MSVC 2017. File is +located at: generate/msvc2017/readme.txt + +2) iASL Compiler/Disassembler and ACPICA tools: + +iASL: Fixed a regression found in version 20200214. Prevent iASL from +emitting an extra byte of garbage data when control methods declared a +single parameter type without using braces. This extra byte is known to +cause a blue screen on the Windows AML interpreter. + +iASL: Made a change to allow external declarations to specify the type of +a named object even when some name segments are not defined. +This change allows the following ASL code to compile (When DEV0 is not +defined or not defined yet): + + External (\_SB.DEV0.OBJ1, IntObj) + External (\_SB.DEV0, DeviceObj) + +iASL: Fixed a problem where method names in "Alias ()" statement could be +misinterpreted. They are now interpreted correctly as method invocations. + +iASL: capture a method parameter count (Within the Method info segment, +as well as the argument node) when using parameter type lists. + +---------------------------------------- + + 28 May 2020.
