ACPICA commit 51a49c2fb4a73f302a6df2b8ddc1350dd261684d

It is better to use unified ASL path name to interact with the developers.

Lv Zheng a2352db584 ACPICA: Disassembler: Cleanup acpi_gbl_db_opt_verbose acpiexec usage
ACPICA commit 42d7ad7bfb1cfb95183c1386c77509f2036f521d

When acpi_gbl_db_opt_verbose is used in acpi_dm_descending_op() (invoked by
acpi_dm_disassemble()), it is actually exported by the disassembler but used
by the debugger to distinguish the output of the disassembler for different
debugger commands. It is by default TRUE but is set to FALSE for control
method disassembly command - "disassemble". So it's initialization should
be a part of the ACPI_DISASSEMBLER conditioned code. This patch uses
ACPI_INIT_GLOBAL to achieve a clean manner so that when ACPI_DISASSEMBLER
is not defined, ACPI_DEBUGGER conditioned code needn't link to this option.
Since it is a disassembler exported variable, it is renamed to
acpi_gbl_dm_opt_Verbose in this patch.

As VERBOSE_PRINT() macro has only one user, this patch also removes the
definition of this macro. Lv Zheng.

This patch doesn't affect Linux kernel.

Lv Zheng 1bdc63bf05 ACPICA: Disassembler: Cleanup acpi_gbl_db_opt_disasm
ACPICA commit 969989cf7f85e2a2a0cd048cd25fc706246a48a2

This patch cleans up the following global variable - acpi_gbl_db_opt_disasm:
The setting is used to control the full disassembly feature for iasl. ACPI
debugger (acpiexec) shall have nothing to do with it. Actually, acpiexec
never links to ad_aml_disassemble().

This patch thus renames this global option to acpi_gbl_dm_opt_disasm and
removes all acpiexec and debugger references on it. Lv Zheng.

Lv Zheng f8fb4c383e ACPICA: Debugger: Split debugger initialization/termination APIs
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.

Lv Zheng 8ec3f45907 ACPICA: Tables: Fix global table list issues by removing fixed table indexes
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.

Lv Zheng ab6c573320 ACPICA: Executer: Add interpreter tracing mode for method tracing facility
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.

Lv Zheng a616dc2fe5 ACPICA: Dispatcher: Add trace support for interpreter
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.

Lv Zheng 0bac429552 ACPICA: Dispatcher: Move stack traversal code to dispatcher
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.

Lv Zheng d1e7ffe50b ACPICA: Namespace: Add function to directly return normalized full path
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.

Lv Zheng 62eb935b77 ACPICA: Dispatcher: Cleanup union acpi_operand_object's AML address assignments
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.

Lv Zheng 950a429cd2 ACPICA: Parser: Cleanup aml_offset in union acpi_operand_object
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). Lv 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.
