Summary of changes for version 20171110: + + +1) ACPICA kernel-resident subsystem: + +This release implements full support for ACPI 6.2A: + NFIT - Added a new subtable, "Platform Capabilities Structure" +No other changes to ACPICA were required, since ACPI 6.2A is primarily an +errata release of the specification. + +Other ACPI table changes: + IORT: Added the SMMUv3 Device ID mapping index. Hanjun Guo + PPTT: Added cache attribute flag definitions to actbl1.h. Jeremy +Linton + +Utilities: Modified the string/integer conversion functions to use +internal 64-bit divide support instead of a native divide. On 32-bit +platforms, a 64-bit divide typically requires a library function which +may not be present in the build (kernel or otherwise). + +Implemented a targeted error message for timeouts returned from the +Embedded Controller device driver. This is seen frequently enough to +special-case an AE_TIME returned from an EC operation region access: + "Timeout from EC hardware or EC device driver" + +Changed the "ACPI Exception" message prefix to "ACPI Error" so that all +runtime error messages have the identical prefix. + + +2) iASL Compiler/Disassembler and Tools: + +AcpiXtract: Fixed a problem with table header detection within the +acpidump file. Processing a table could be ended early if a 0x40 (@) +appears in the original binary table, resulting in the @ symbol appearing +in the decoded ASCII field at the end of the acpidump text line. The +symbol caused acpixtract to incorrectly think it had reached the end of +the current table and the beginning of a new table. + +AcpiXtract: Added an option (-f) to ignore some errors during table +extraction. This initial implementation ignores non-ASCII and non- +printable characters found in the acpidump text file. + +TestSuite(ASLTS)/AcpiExec: Fixed and restored the memory usage statistics +for ASLTS. This feature is used to track memory allocations from +different memory caches within the ACPICA code. At the end of an ASLTS +run, these memory statistics are recorded and stored in a log file. + +Debugger (user-space version): Implemented a simple "Background" command. +Creates a new thread to execute a control method in the background, while +control returns to the debugger prompt to allow additional commands. + Syntax: Background <Namepath> [Arguments] + +---------------------------------------- 29 September 2017.
