2015-07-23ACPICA: Executer: Add OSL trace hook supportLv Zheng
ACPICA commit e8e4a9b19d0b72a7b165398bdc961fc2f6f502ec This patch adds OSL trace hook support. OSPMs are encouraged to use acpi_os_trace_point() with ACPI_USE_SYSTEM_TRACER defined to implement platform specific trace facility. Lv Zheng.

2015-07-23ACPICA: Executer: Add interpreter tracing mode for method tracing facilityLv Zheng
ACPICA commit 07fffd02607685b655ed92ee15c160e6a810b60b The acpi_debug_trace() is the mechanism known as ACPI method tracing that is used by Linux as ACPICA debugging message reducer. This facility can be controlled through Linux ACPI subsystem - /sys/module/acpi/parameters. This facility requires CONFIG_ACPI_DEBUG to be enabled to see ACPICA trace logs in the kernel dmesg output. This patch enhances acpi_debug_trace() to make it not only a message reducer, but a real tracer to trace AML interpreter execution. Note that in addition to the AML tracer enabling, this patch also updates the facility with the following enhancements: 1. Allow a full path to be specified by the acpi_debug_trace() API. 2. Allow any method rather than just the entrance of acpi_evaluate_object() to be traced. 3. All interpreter ACPI_LV_TRACE_POINT messages are collected for ACPI_EXECUTER layer. The Makefile of drivers/acpi/acpica is also updated to include exdebug.o and the duplicated stubs are removed after that. Note that since this patch has enhanced the method tracing facility, Linux need also be updated after applying this patch. Lv Zheng.

ACPICA commit 9a2b638acb3a7215209432e070c6bd0312374229 ACPI Device object often contains a _CLS object to supply PCI-defined class code for the device. This patch introduces logic to process the _CLS object. Suravee Suthikulpanit, Lv Zheng.

2014-03-26ACPICA: Remove global option to serialize all control methods.Lv Zheng
According to the reports, the "acpi_serialize" mechanism is broken as: A. The parallel method calls can still happen when the interpreter lock is released under the following conditions: 1. External callbacks are invoked, for example, by the region handlers, the exception handlers, etc.; 2. Module level execution is performed when Load/LoadTable opcodes are executed, and 3. The _REG control methods are invoked to complete the region registrations. B. For the following situations, the interpreter lock need to be released even for a serialized method while currently, the lock-releasing operation is marked as a no-op by acpi_ex_relinquish/reacquire_interpreter() when this mechanism is enabled: 1. Wait opcode is executed, 2. Acquire opcode is executed, and 3. Sleep opcode is executed. This patch removes this mechanism and the internal acpi_ex_relinquish/reacquire_interpreter() APIs. Lv Zheng.

2014-02-27ACPICA: Headers: Deploy #pragma pack (push) and (pop).Bob Moore
Use push and pop to both guarantee that the correct alignment is used, and to restore the alignment to whatever it was before the header was included. It is reported that the #pragma pack(push/pop) directives are not supported by the specific GCCs, but this patch still doesn't affect kernel build as there are already #pragma pack([1]) directives used in the old ACPICA headers, which means there shouldn't be GCCs that are currently used to compile the ACPI kernels do not support #pragma pack() directives.

Some ASL compilers allow 64-bit constants within a 32-bit table (DSDT version == 1). When encountered, emit a warning that the constant will be truncated to 32 bits.

2010-01-22ACPICA: Remove obsolete ACPI_INTEGER (acpi_integer) typeBob Moore
This type was introduced as the code was migrated from ACPI 1.0 (with 32-bit AML integers) to ACPI 2.0 (with 64-bit integers). It is now obsolete and this change removes it from the ACPICA code base, replaced by u64. The original typedef has been retained for now for compatibility with existing device driver code.

These changes will require an update to all callers of this interface. See the ACPICA Programmer Reference for details.
