[PATCH] tools/power/acpi: Introduce acpi_validate with manpage for easy validation of ACPI BIOS tables
by Thomas Renninger
The used iasl compiler shares the same code base as the kernel.
Warnings or errors mostly point to bad BIOSes.
These errors should get reported to the BIOS vendors and may indicated that
acpica (kernel ACPI parts) need compatibility adjustings.
Why is an extra tool needed for this?
The dynamic ACPI Source Language (ASL) parts are located in DSDT and often
multiple SSDT tables. Those often have dependencies to each other and the iasl
compiler often cannot resolve external symbols correctly if they are not
passed as external tables (iasl -e option) when tables get disassembled.
This quickly leads to false positive errors.
This tool makes sure disassembling and recompilation is done correctly.
This tool is also made for ACPI BIOS table verification for BIOS vendors and
hardware certification tools for distributions.
Hardware which supports Linux must/should not show any warnings or errors.
Remarks and optimization hints in the logs can be used to further enhance
the ACPI BIOS code.
Warnings and errors mostly describe the issues in a way, so that they can
get passed to and used by BIOS developers to fix the problems easily.

+.TH ACPI_VALIDATE 8
+.SH NAME
+acpi_validate \- Extracts, disassembles and recompiles ACPI BIOS tables.
+.SH SYNOPSIS
+.ft B
+.B acpica_validate [ \-o output_dir ] [ \-a acpidump ] [ \-v ] [ \-c compile_options ] [ \-d disassemble_options ]
+.SH DESCRIPTION
+\fBacpi_validate \fP extracts, disassembles and recompiles ACPI BIOS
+tables. The disassembled files will be copied into the local or specified
+output directory (-o option).
+
+The underlying iasl compiler verifies and may complain about correctness of
+some of the BIOS tables. Warnings or errors can give a pointer to possible
+malfunction of the system. The Linux kernel uses the same code base as the
+iasl interpreter which is used to validate tables.
+
+The ASL (ACPI Source Language) files (*.dsl) can get recompiled manually via
+\fBiasl -sa\fP and the resulting compilation (*.aml) can get passed to the
+kernel via the "Overriding ACPI tables via initrd" mechanism. Only use this
+feature if you know what you are doing. Read
+Documentation/acpi/initrd_table_override.txt (part of the kernel sources) for
+further information.
+
+If you think you found a bug in the iasl compiler or related
+tools, you can ask here for help: \fBdevel(a)acpica.org\fP
+
+You may also want to ask there if you are not sure whether it really
+is a BIOS bug.
+
+If you are sure you found a BIOS issue, complain to your hardware vendor. The
+iasl compiler typically provides a description of the warning/error in a way,
+so that BIOS authors can easily fix it.
+
+.SH OPTIONS
+\fB-o output_dir\fP
+
+The output directory where extracted, disassembled and
+recompiled tables are copied to. Compiler output is located in a log
+subdirectory, warnings and errors found by the compiler are located in the err
+directory.
+.PP
+\fB-a acpidump\fP
+
+Take this acpidump file instead of dumping and extracting
+ACPI tables from the local machine
+.PP
+\fB-v\fP
+
+Be more verbose
+.PP
+\fB-c options\fP
+
+Override default iasl compile options (default -sa -cr -vr)
+.PP
+\fB-d options\fP
+
+Override default iasl disassemble options
+
+.SH NOTES
+
+.B "acpi_validate"
+must be run as root.

AcpiGetEventStatus: interface with behavior
by Andriy Gapon
AcpiGetEventStatus has an out parameter of type ACPI_EVENT_STATUS.
My impression that values of that type should conform to bit definitions
provided near the type declaration (ACPI_EVENT_FLAG_ENABLED,
ACPI_EVENT_FLAG_SET, etc).
But it seems that currently AcpiGetEventStatus returns only values zero and one
corresponding to inactive and active status.
The linux (adaption of the) code here
http://lxr.linux.no/#linux+v3.7.1/drivers/acpi/acpica/evxfevnt.c#L313
seems to be a bit more elaborate. It actually tries to produce a value that
conforms to the definitions by examining not only the status register but also
enable register.
It looks like AcpiHwGetGpeStatus is the model for how ACPI_EVENT_STATUS should
be populated. I am not sure if AcpiGetEventStatus should be made compatible
with ACPI_EVENT_STATUS or if its out type should be changed to something else.
Also, it looks that the comment near ACPI_EVENT_STATUS definitions is a little
bit out of sync.

[RFC PATCH] ACPI: Add boot option to disable auto return object repair
by Lv Zheng
There is automatic return object repair mechanism implemented in
ACPICA which can not handle all of the issues exposed by BIOS
currently. This patch allow a kernel boots up without such
workarounds enabled. A better choice should refine the repair
mechanism to allow more robust evaluation result.

[PATCH 1/1] ACPICA: Table: Add VRTC table support.
by Lv Zheng
VRTC is used in Intel MID platforms as a replacement of the traditional
x86 RTC. VRTC table can be found in the recent ACPI BIOS enabled MID
platforms. The format of this table has been defined in the "Simple
Firmware Interface Specification".
This patch introduces VRTC table support into ACPICA.

I am looking for a male friend
by Belousova
I'm looking for my soul mate!
I am a young and confident lady.
I do believe in love founded on a deep passion and even deeper respect
And I know how to love and cherish a truly fine man. I appreciate in men their ability to communicate with lady. I am a kind and caring woman and I have nothing to hide from you.
My dream is to create a family with a deserving man.
Here are my photos and my profile, perhaps http://tinyurl.com/hsmiZbQK9O you are my destiny.

ACPICA version 20130117 released
by Moore, Robert
17 January 2013. Summary of changes for version 20130117:
This release is available at https://www.acpica.org/downloads
The ACPI 5.0 specification is available at www.acpi.info
1) ACPICA Kernel-resident Subsystem:
Updated the AcpiGetSleepTypeData interface: Allow the \_Sx methods to return either 1 or 2 integers. Although the ACPI spec defines the \_Sx objects to return a package containing one integer, most BIOS code returns two integers and the previous code reflects that. However, we also need to support BIOS code that actually implements to the ACPI spec, and this change reflects this.
Fixed two issues with the ACPI_DEBUG_PRINT macros:
1) Added the ACPI_DO_WHILE macro to the main DEBUG_PRINT helper macro for C compilers that require this support.
2) Renamed the internal ACPI_DEBUG macro to ACPI_DO_DEBUG_PRINT since ACPI_DEBUG is already used by many of the various hosts.
Updated all ACPICA copyrights and signons to 2013. Added the 2013 copyright to all module headers and signons, including the standard Linux header. This affects virtually every file in the ACPICA core subsystem, iASL compiler, all ACPICA utilities, and the test suites.
Example Code and Data Size: These are the sizes for the OS-independent acpica.lib produced by the Microsoft Visual C++ 9.0 32-bit compiler. The debug version of the code includes the debug output trace mechanism and has a much larger code and data size.
Previous Release:
Non-Debug Version: 94.5K Code, 25.5K Data, 120.0K Total
Debug Version: 182.2K Code, 74.9K Data, 257.1K Total
Current Release:
Non-Debug Version: 94.5K Code, 25.4K Data, 119.9K Total
Debug Version: 182.3K Code, 75.0K Data, 257.3K Total
2) iASL Compiler/Disassembler and Tools:
Generic Unix OSL: Use a buffer to eliminate multiple vfprintf()s and prevent a possible fault on some hosts. Some C libraries modify the arg pointer parameter to vfprintf making it difficult to call it twice in the AcpiOsVprintf function. Use a local buffer to workaround this issue. This does not affect the Windows OSL since the Win C library does not modify the arg pointer. Chao Guan, Bob Moore.
iASL: Fixed a possible infinite loop when the maximum error count is reached. If an output file other than the .AML file is specified (such as a listing file), and the maximum number of errors is reached, do not attempt to flush data to the output file(s) as the compiler is aborting. This can cause an infinite loop as the max error count code essentially keeps calling itself.
iASL/Disassembler: Added an option (-in) to ignore NOOP opcodes/operators. Implemented for both the compiler and the disassembler. Often, the NOOP opcode is used as padding for packages that are changed dynamically by the BIOS. When disassembled and recompiled, these NOOPs will cause syntax errors. This option causes the disassembler to ignore all NOOP opcodes (0xA3), and it also causes the compiler to ignore all ASL source code NOOP statements as well.
Debugger: Enhanced the Sleep command to execute all sleep states. This change allows Sleep to be invoked with no arguments and causes the debugger to execute all of the sleep states, 0-5, automatically.
