When the debugger is running in the kernel mode, acpi_db_single_step() may
also be invoked by the kernel runtime code path but the single stepping
command prompt may be erronously logged as the kernel logs and runtime code
path cannot proceed.
This patch fixes this issue by adding acpi_gbl_db_thread_id for the debugger
thread and preventing acpi_db_single_step() to be invoked from other threads.
It is not suitable to add acpi_thread_id parameter for acpi_os_execute() as
the function may be implemented as work queue on some hosts. So it is
better to let the hosts invoke acpi_set_debugger_thread_id(). Currently
acpiexec is not configured as DEBUGGER_MULTI_THREADED, but we can do this.
When we do this, it is better to invoke acpi_set_debugger_thread_id() in
acpi_os_execute() when the execution type is OSL_DEBUGGER_MAIN_THREAD. The
support should look like:
create_thread(&tid);
if (type == OSL_DEBUGGER_MAIN_THREAD)
acpi_set_debugger_thread_id(tid);
resume_thread(tid);
Similarly, semop() may be used for pthread implementation. But this patch
simply skips debugger thread ID check for application instead of
introducing such complications as there is no need to skip
acpi_db_single_step() for an application debugger - acpiexec.
Note that the debugger thread ID can also be used by acpi_os_printf() to
filter out debugger output. Lv Zheng.

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.

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 f7b86f35416e3d1f71c3d816ff5075ddd33ed486
The following commit is reported to have broken s2ram on some platforms:
Commit: 0249ed2444
ACPICA: Add option to favor 32-bit FADT addresses.
The platform reports 2 FACS tables (which is not allowed by ACPI
specification) and the new 32-bit address favor rule forces OSPMs to use
the FACS table reported via FADT's X_FIRMWARE_CTRL field.
The root cause of the reported bug might be one of the followings:
1. BIOS may favor the 64-bit firmware waking vector address when the
version of the FACS is greater than 0 and Linux currently only supports
resuming from the real mode, so the 64-bit firmware waking vector has
never been set and might be invalid to BIOS while the commit enables
higher version FACS.
2. BIOS may favor the FACS reported via the "FIRMWARE_CTRL" field in the
FADT while the commit doesn't set the firmware waking vector address of
the FACS reported by "FIRMWARE_CTRL", it only sets the firware waking
vector address of the FACS reported by "X_FIRMWARE_CTRL".
This patch excludes the cases that can trigger the bugs caused by the root
cause 2.
There is no handshaking mechanism can be used by OSPM to tell BIOS which
FACS is currently used. Thus the FACS reported by "FIRMWARE_CTRL" may still
be used by BIOS and the 0 value of the 32-bit firmware waking vector might
trigger such failure.
This patch tries to favor 32bit FACS address in another way where both the
FACS reported by "FIRMWARE_CTRL" and the FACS reported by "X_FIRMWARE_CTRL"
are loaded so that further commit can set firmware waking vector in the
both tables to ensure we can exclude the cases that trigger the bugs caused
by the root cause 2. The exclusion is split into 2 commits as this commit
is also useful for dumping more ACPI tables, it won't get reverted when
such exclusion is no longer necessary. Lv Zheng.

ACPICA commit d115fe2ffdab449d6107d58580c5afd0a81d65fe
This change adds the basic low-level infrastructure for the External
AML opcode. The interpreter will simply ignore this op, as the op
is intended for use by the disassembler only.
Note that External() opcode is useful for disassembler, interpreter
can simply ignore it and still return exceptions for unknown control
methods so the kernel part only includes the grammar definition of
External() opcode in order to ignore it but doesn't interpret it.

There is a race condition between acpi_hw_disable_all_gpes() or
acpi_enable_all_wakeup_gpes() and acpi_ev_asynch_enable_gpe() such
that if the latter wins the race, it may mistakenly enable a GPE
disabled by the former. This may lead to premature system wakeups
during system suspend and potentially to more serious consequences.
The source of the problem is how acpi_hw_low_set_gpe() works when
passed ACPI_GPE_CONDITIONAL_ENABLE as the second argument. In that
case, the GPE will be enabled if the corresponding bit is set in the
enable_for_run mask of the GPE enable register containing that bit.
However, acpi_hw_disable_all_gpes() and acpi_enable_all_wakeup_gpes()
don't modify the enable_for_run masks of GPE registers when writing
to them. In consequence, if acpi_ev_asynch_enable_gpe(), which
eventually calls acpi_hw_low_set_gpe() with the second argument
equal to ACPI_GPE_CONDITIONAL_ENABLE, is executed in parallel with
one of these functions, it may reverse changes made by them.
To fix the problem, introduce a new enable_mask field in struct
acpi_gpe_register_info in which to store the current mask of
enabled GPEs and modify acpi_hw_low_set_gpe() to take this
mask into account instead of enable_for_run when its second
argument is equal to ACPI_GPE_CONDITIONAL_ENABLE. Also modify
the low-level routines called by acpi_hw_disable_all_gpes(),
acpi_enable_all_wakeup_gpes() and acpi_enable_all_runtime_gpes()
to update the enable_mask masks of GPE registers after all
(successful) writes to those registers.

Changes to correct several GPIO issues:
1) The update_rule in a GPIO field definition is now ignored;
a read-modify-write operation is never performed for GPIO fields.
(Internally, this means that the field assembly/disassembly
code is completely bypassed for GPIO.)
2) The Address parameter passed to a GPIO region handler is
now the bit offset of the field from a previous Connection()
operator. Thus, it becomes a "Pin Number Index" into the
Connection() resource descriptor.
3) The bit_width parameter passed to a GPIO region handler is
now the exact bit width of the GPIO field. Thus, it can be
interpreted as "number of pins".
Overall, we can now say that the region handler interface
to GPIO handlers is a raw "bit/pin" addressed interface, not
a byte-addressed interface like the system_memory handler interface.

This is a cosmetic patch only. Comparison of the resulting binary showed
only line number differences.
This patch does not affect the generation of the Linux binary.
This patch decreases 210 lines of 20121018 divergence.diff.
The ACPICA source codes uses a totally different indentation style from the
Linux to be compatible with other users (operating systems or BIOS).
Indentation differences are critical to the release automation. There are
two causes related to the "indentation" that are affecting the release
automation:
1. The ACPICA -> Linux release process is:
ACPICA source -- acpisrc - hierarchy - indent ->
linuxized ACPICA source -- diff ->
linuxized ACPICA patch (x) -- human intervention ->
linuxized ACPICA patch (o)
Where
'x' means "cannot be directly applied to the Linux"
'o' means "can be directly applied to the Linux"
Different "indent" version or "indent" options used in the "indent"
step will lead to different divergences.
The version of "indent" used for the current release process is:
GNU indent 2.2.11
The options of "indent" used for the current release process is:
-npro -kr -i8 -ts8 -sob -l80 -ss -ncs
2. Manual indentation prettifying work in the Linux side will also harm the
automatically generated linuxized ACPICA patches, making them impossible
to apply directly.
This patch fixes source code differences caused by the two causes so that
the "human intervention" can be reduced in the future.

This patch reduces source code diff caused by the simple code maintenance
work:
1. Deletion of the unused include files.
2. Deletion of the deprecated codes blocks.
3. Repositioning of the code blocks.
4. Replacing the values with the well defined macros.
5. Replacing the types with the equivalent types.

This patch updates ACPICA codes surrounded by some disabled build options
so that the source code diff between Linux and ACPICA can be reduced.
Some of these build options may never be used in the kernel, so they may
be deleted entirely in future patches.

This patch reduces the source code diff between Linux and ACPICA by
cleaning the comments that already have been updated in ACPICA.
There is no extra indentation done in this patch. Even the empty line
deletions and insertions are also splitted into another cleanup patch so
that this patch can be easily reviewed, and the binary differences can be
held to a lowest level.
