----------------------------------------
10 November 2017. 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. Summary of changes for version 20170929:
1) ACPICA kernel-resident subsystem:
Redesigned and implemented an improved ASL While() loop timeout
mechanism. This mechanism is used to prevent infinite loops in the kernel
AML interpreter caused by either non-responsive hardware or incorrect AML
code. The new implementation uses AcpiOsGetTimer instead of a simple
maximum loop count, and is thus more accurate and constant across
different machines. The default timeout is currently 30 seconds, but this
may be adjusted later.
Renamed the ACPI_AML_INFINITE_LOOP exception to AE_AML_LOOP_TIMEOUT to
better reflect the new implementation of the loop timeout mechanism.
Updated the AcpiGetTimerDuration interface to cleanup the 64-bit support
and to fix an off-by-one error. Jung-uk Kim.
Fixed an EFI build problem by updating the makefiles to for a new file
that was added, utstrsuppt.c
2) iASL Compiler/Disassembler and Tools:
Implemented full support for the PDTT, SDEV, and TPM2 ACPI tables. This
includes support in the table disassembler, compiler, and template
generator.
iASL: Added an exception for an illegal type of recursive method
invocation. If a method creates named objects, the first recursive call
will fail at runtime. This change adds an error detection at compile time
to catch the problem up front. Note: Marking such a method as
"serialized" will not help with this problem, because the same thread can
acquire the method mutex more than once. Example compiler and runtime
output:
Method (MTH1)
{
Name (INT1, 1)
MTH1 ()
}
dsdt.asl 22: MTH1 ()
Error 6152 - ^ Illegal recursive call to method
that creates named objects (MTH1)
Previous runtime exception:
ACPI Error: [INT1] Namespace lookup failure,
AE_ALREADY_EXISTS (20170831/dswload2-465)
iASL: Updated support for External() opcodes to improve namespace
management and error detection. These changes are related to issues seen
with multiple-segment namespace pathnames within External declarations,
such as below:
External(\_SB.PCI0.GFX0, DeviceObj)
External(\_SB.PCI0.GFX0.ALSI)
iASL: Implemented support for multi-line error/warning messages. This
enables more detailed and helpful error messages as below, from the
initial deployment for the duplicate names error:
DSDT.iiii 1692: Device(PEG2) {
Error 6074 - ^ Name already exists in scope
(PEG2)
Original name creation/declaration below:
DSDT.iiii 93: External(\_SB.PCI0.PEG2, DeviceObj)
AcpiXtract: Added additional flexibility to support differing input hex
dump formats. Specifically, hex dumps that contain partial disassembly
and/or comments within the ACPI table data definition. There exist some
dump utilities seen in the field that create this type of hex dump (such
as Simics). For example:
DSDT @ 0xdfffd0c0 (10999 bytes)
Signature DSDT
Length 10999

Test suite: Miscellaneous changes/fixes:
More cleanup and simplification of makefiles
Continue compilation of test cases after a compile failure
Do not perform binary compare unless both files actually exist
iASL: Performed some code/module restructuring. Moved all memory
allocation functions to new modules. Two new files, aslallocate.c and
aslcache.c
