ACPICA: Executer: Add interpreter tracing mode for method tracing facility

2015-07-23T21:09:07Z

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: Dispatcher: Add trace support for interpreter

2015-07-23T21:09:07Z

ACPICA commit 71299ec8b49054daace0df50268e8e055654ca37 This patch adds trace point at the following point: 1. Begin/end of a control method execution; 2. Begin/end of an opcode execution. The trace point feature can be enabled by defining ACPI_DEBUG_OUTPUT and specifying a debug level that includes ACPI_LV_TRACDE_POINT and the debug layers that include ACPI_PARSER and ACPI_DISPACTCHER. In order to make aml_op_name of union acpi_parse_object usable for tracer, it is enabled for ACPI_DEBUG_OUTPUT in this patch. Lv Zheng.

ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address assignments

2015-07-23T21:09:06Z

ACPICA commit afb52611dbe7403551f93504d3798534f5c343f4 This patch cleans up the code of assigning the AML address to the union acpi_operand_object. The idea behind this cleanup is: The AML address of the union acpi_operand_object should always be determined at the point where the object is encountered. It should be started from the first byte of the object. For example, the opcode of the object, the name string of the user_term object, or the first byte of the packaged object (where a pkg_length is prefixed). So it's not cleaner to have it assigned here and there in the entire ACPICA source tree. There are some special cases for the internal opcodes, before cleaning up the internal opcodes, we should also determine the rules for the AML addresses of the internal opcodes: 1. INT_NAMEPATH_OP: the address of the first byte for the name_string. 2. INT_METHODCALL_OP: the address of the first byte for the name_string. 3. INT_BYTELIST_OP: the address of the first byte for the byte_data list. 4. INT_EVAL_SUBTREE_OP: the address of the first byte for the Region/Package/Buffer/bank_field/Field arguments. 5. INT_NAMEDFIELD_OP: the address to the name_seg. 6. INT_RESERVEDFIELD_OP: the address to the 0x00 prefix. 7. INT_ACCESSFIELD_OP: the address to the 0x01 prefix. 8. INT_CONNECTION_OP: the address to the 0x02 prefix. 9: INT_EXTACCESSFIELD_OP: the address to the 0x03 prefix. 10.INT_RETURN_VALUE_OP: the address of the replaced operand. 11.computational_data: the address to the Byte/Word/Dword/Qword/string_prefix. Before cleaning up the internal root scope of the aml_walk, turning it into the term_list, we need to remember the aml_start address as the "Aml" attribute for the union acpi_operand_object created by acpi_ps_create_scope_op(). Finally, we can delete some redundant AML address assignment in psloop.c.

ACPICA: Fix indent caused divergences.

2012-11-14T23:31:23Z

New version of "indent" program will generate different outputs that will lead to the divergences between the Linux and the ACPICA. This patch fixes such divergences caused by the "indent" program. The version of the "indent" used for this patch is "GNU indent 2.2.11". This patch will not affect the generated vmlinux binary. This will decrease 581 lines of 20120913 divergence.diff.
