2018-10-18ACPICA: Remove acpi_gbl_group_module_level_code and only use ↵Erik Schmauss
acpi_gbl_execute_tables_as_methods instead acpi_gbl_group_module_level_code and acpi_gbl_execute_tables_as_methods were used to enable different table load behavior. The different table load behaviors are as follows: A.) acpi_gbl_group_module_level_code enabled the legacy approach where ASL if statements are executed after the namespace object has been loaded. B.) acpi_gbl_execute_tables_as_methods is currently used to enable the table load to be a method invocation. This meaning that ASL If statements are executed in-line rather than deferred until after the ACPI namespace has been populated. This is the correct behavior and option A will be removed in the future. We do not support a table load behavior where these variables are assigned the same value. In otherwords, we only support option A or B and do not need acpi_gbl_group_module_level_code to enable A. From now on, acpi_gbl_execute_tables_as_methods == 0 enables option A and acpi_gbl_execute_tables_as_methods == 1 enables option B. Note: option A is expected to be removed in the future and option B will become the only supported table load behavior. Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Rafael J.

2018-10-18ACPICA: AML Parser: fix parse loop to correctly skip erroneous extended opcodesErik Schmauss
AML opcodes come in two lengths: 1-byte opcodes and 2-byte, extended opcodes. If an error occurs due to illegal opcodes during table load, the AML parser needs to continue loading the table. In order to do this, it needs to skip parsing of the offending opcode and operands associated with that opcode. This change fixes the AML parse loop to correctly skip parsing of incorrect extended opcodes. Previously, only the short opcodes were skipped correctly.

2018-07-29ACPICA: AML Parser: ignore control method status in module-level codeErik Schmauss
Previous change in the AML parser code blindly set all non-successful dispatcher statuses to AE_OK. That approach is incorrect, though, because successful control method invocations from module-level return AE_CTRL_TRANSFER. Overwriting AE_OK to this status causes the AML parser to think that there was no return value from the control method invocation.

2018-07-23ACPICA: AML Parser: ignore dispatcher error status during table loadSchmauss, Erik
The dispatcher and the executer process the parse nodes During table load. Error status from the evaluation confuses the AML parser. This results in the parser failing to complete parsing of the current scope op which becomes problematic. For the incorrect AML below, _ADR never gets created. definition_block(...) { Scope (\_SB) { Device (PCI0){...} Name (OBJ1, 0x0) OBJ1 = PCI0 + 5 // Results in an operand error. } // \_SB not closed // parser looks for \_SB._SB.PCI0, results in AE_NOT_FOUND error // Entire scope block gets skipped. Scope (\_SB.PCI0) { Name (_ADR, 0x0) } } Fix the above error by properly completing the initial \_SB scope after an error by clearing errors that occur during table load. In the above case, this means that OBJ1 = PIC0 + 5 is skipped.

2018-06-06ACPICA: AML parser: attempt to continue loading table after errorErik Schmauss
This change alters the parser so that the table load does not abort upon an error. Notable changes: If there is an error while parsing an element of the termlist, we will skip parsing the current termlist element and continue parsing to the next opcode in the termlist. If we get an error while parsing the conditional of If/Else/While or the device name of Scope, we will skip the body of the statement all together and pop the parser_state. If we get an error while parsing the base offset and length of an operation region declaration, we will remove the operation region from the namespace.

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.

2015-07-23ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address assignmentsLv Zheng
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.

2015-07-23ACPICA: Parser: Cleanup aml_offset in union acpi_operand_objectLv Zheng
ACPICA commit 61b360074fde2bb8282722579410f5d1fb12f84d This patch converts aml_offset in union acpi_operand_object to AML address. AML offset is actually only used by the debugger, using AML address is more direct and efficient during the parsing stage so that we don't need to calculate the offset during the parsing stage and will not have difficulities in converting it into other offset attributes. Sometimes, aml_offset is not an indication of the offset from the table header but the offset from the entry of a list of terms, which requires additional efforts to convert it into an offset from the table header. By using AML address directly, there is no such difficulty. Thus this patch also deletes a logic in disassembler that is trying to convert the aml_offset from "offset from the start address of Method/Package/Buffer" into the "offset from the start address of the ACPI table" (Sample code deletion can be seen in acpi_dm_deferred_parse(), but the function is not in the Linux kernel).

2015-07-23ACPICA: Parser: Cleanup aml_offset in struct acpi_walk_stateLv Zheng
ACPICA commit d254405814495058276c0c2f9d96794d15a6c91c This patch converts aml_offset in struct acpi_walk_state to AML address. AML offset is actually only used by the debugger, using AML address is more direct and efficient during the parsing stage so that we don't need to calculate it during the parsing stage. On the other hand, we can see several issues in the current parser logic around the aml_offset: 1. union acpi_operand_object.Common.aml_offset is redundantly assigned in acpi_ps_parse_loop(). 2. aml_offset is not an indication of the offset from the table header but the offset from the entry of a list of objects. Sometimes, it indicates an entry for a Method/Package/Buffer, which makes it difficult to be reversely calculated to a table header offset. 3. When being used with method tracers (for example, Linux function trace), it's better to have AML address logged instead of the AML offset because the address is the only attribute that can uniquely identify the opcode. This patch is required to solve the above issues. Lv Zheng.

This feature is disabled by default and this patch also adds a new Linux kernel parameter "acpi_auto_serialize" to allow this feature to be turned on for a specific boot.

2011-01-18ACPICA: Fix issues/fault with automatic "serialized" method supportLin Ming
History: This support changes a method to "serialized" on the fly if the method generates an AE_ALREADY_EXISTS error, indicating the possibility that it cannot handle reentrancy. This fix repairs a couple of issues seen in the field, especially on machines with many cores. 1) Delete method children only upon the exit of the last thread, so as to not delete objects out from under running threads. 2) Set the "serialized" bit for the method only upon the exit of the last thread, so as to not cause deadlock when running threads attempt to exit. 3) Cleanup the use of the AML "MethodFlags" and internal method flags so that there is no longer any confustion between the two.

2009-08-28ACPICA: Add support for module-level executable AML codeLin Ming
Add limited support for executable AML code that exists outside of any control method. This type of code has been illegal since ACPI 2.0. The code must exist in an If/Else/While block. All AML tables are supported, including tables that are dynamically loaded.
