2016-05-05ACPICA: Divergence: remove unwanted spaces for typedefLv Zheng1-1/+1
ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f This patch removes unwanted spaces for typedef. This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

2015-10-22ACPI: Enable build of AML interpreter debuggerLv Zheng1-2/+0
This patch enables ACPICA debugger files using a configurable CONFIG_ACPI_DEBUGGER configuration item. Those debugger related code that was originally masked as ACPI_FUTURE_USAGE now gets unmasked. Necessary OSL stubs are also added in this patch: 1. acpi_os_readable(): This should be arch specific in Linux, while this patch doesn't introduce real implementation and a complex mechanism to allow architecture specific acpi_os_readable() to be implemented to validate the address. It may be done by future commits. 2. acpi_os_get_line(): This is used to obtain debugger command input. This patch only introduces a simple KDB concept example in it and the example should be co-working with the code implemented in acpi_os_printf(). Since this KDB example won't be compiled unless ENABLE_DEBUGGER is defined and it seems Linux has already stopped to use ENABLE_DEBUGGER, thus do not expect it can work properly. This patch also cleans up all other ACPI_FUTURE_USAGE surroundings accordingly. 1. Since linkage error can be automatically detected, declaration in the headers needn't be surrounded by ACPI_FUTURE_USAGE. So only the following separate exported fuction bodies are masked by this macro (other exported fucntions may have already been masked at entire module level via drivers/acpi/acpica/Makefile): acpi_install_exception_handler() acpi_subsystem_status() acpi_get_system_info() acpi_get_statistics() acpi_install_initialization_handler() 2. Since strip can automatically zap the no-user functions, functions that are not marked with ACPI_EXPORT_SYMBOL() needn't get surrounded by ACPI_FUTURE_USAGE. So the following function which is not used by Linux kernel now won't get surrounded by this macro: acpi_ps_get_name() Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

2015-07-24ACPICA: Executer: Add interpreter tracing mode for method tracing facilityLv Zheng1-0/+18
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.

2014-03-26ACPICA: Remove global option to serialize all control methods.Lv Zheng1-4/+0
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 Moore1-0/+4
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.
