ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432 It is likely that the debugger is enabled only when a userspace program explicitly tells a kernel to do so, so it shouldn't be initialized as early as current implementation. The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to call the new APIs by itself. And BSD developers may also get notified to invoke the APIs for DDB enabling. Lv Zheng. This patch doesn't affect Linux kernel as debugger is currently not enabled in the Linux kernel. Link: https://github.com/acpica/acpica/commit/7a3f22baSigned-off-by:

ACPICA commit 3f42ba76e2a0453976d3108296d5f656fdf2bd6e In this patch, FACS table mapping is also tuned a bit so that only the selected FACS table will be mapped by the OSPM (mapped on demand) and the FACS related global variables can be reduced.

ACPICA commit c0b38b4c3982c2336ee92a2a14716107248bd941 The fixed table indexes leave holes in the global table list: 1. One hole can be seen when there is only 1 FACS provided by the BIOS. 2. Tow holes can be seen when it is a reduced hardware platform. The holes do not break OSPMs but have broken ACPI debugger "tables" command. Also the "fixed table indexes" mechanism may make the descriptors of the standard tables installed earlier than DSDT to be overwritten by the descriptors of the fixed tables. For example, FACP disappears from the global table list after DSDT is installed. This patch fixes all above issues by removing the "fixed table indexes" mechanism which is too complicated to be maintained in a regression safe manner. After removal, the table loader will determine the indexes of the fixed tables. Lv Zheng. Link: https://github.com/acpica/acpica/commit/c0b38b4cSigned-off-by:

A new global was needed to ensure the listing mode is completely separate from the debugger verbose mode. Emits the correct AML offset for the AML code.

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 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 commit c8275e243b58fd4adfc0362bd704af41ed14bc75 This patch moves parts of acpi_dm_dump_method_info() to the dispatcher component. This patch also makes the new function dependent on ACPI_DEBUG_OUTPUT compile-stage definition so that it can be used by the trace facility. acpi_dm_dump_method_info() traverses method stack when an exception is encountered. Such traversal is needed to support method tracing for the exceptions. When an exception is encountered, the end indications of the aborted methods should be logged in order not to break the user space analysis tool. Lv Zheng.

ACPICA commit 6e0229bb156d71675f2e07dc7960adb7ec0a60ea This patch adds functions to return normalized full path instead of "external path". The external path contains trailing "_" for each name segment while the normalized full path doesn't contain the trailing "_". Currently this function is used by the method tracing users to specify a none trailing "_" attached name path. Lv Zheng. Note that we need to validate and switch all Linux kernel acpi_get_name() users to use the new name type before removing the old name type from ACPICA.

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. Link: https://github.com/acpica/acpica/commit/afb52611Signed-off-by: -

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).

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. Link: https://github.com/acpica/acpica/commit/d2544058Signed-off-by:
