ACPICA commit a65c1df7e6b4bad8e37df822018c40c6c446add9
The key feature of this utility is that the original comments within
the input ASL files are preserved during the conversion process, and
included within the converted ASL+ file -- thus creating a transparent
conversion of existing ASL files to ASL+ (ASL 2.0)
This patch is an automatic generation of the ASL converter commit,
Linux kernel isn't affected by the functionality provided in this
commit, but requires the linuxized changes to support future ACPICA
release automation.

ACPICA commit 23a417ca406a527e7ae1710893e59a8b6db30e14
There is a facility in Linux, developers can control the enabling/disabling
of a GPE via /sys/firmware/acpi/interrupts/gpexx. This is mainly for
debugging purposes.
But many users expect to use this facility to implement quirks to mask a
specific GPE when there is a gap in Linux causing this GPE to flood. This
is not working correctly because currently this facility invokes
enabling/disabling counting based GPE driver APIs:
acpi_enable_gpe()/acpi_disable_gpe()
and the GPE drivers can still affect the count to mess up the GPE
masking purposes.
However, most of the IRQ chip designs allow masking/unmasking IRQs via a
masking bit which is different from the enabled bit to achieve the same
purpose. But the GPE hardware doesn't contain such a feature, this brings
the trouble.
In this patch, we introduce a software mechanism to implement the GPE
masking feature, and acpi_mask_gpe() are provided to the OSPMs to
mask/unmask GPEs in the above mentioned situation instead of
acpi_enable_gpe()/acpi_disable_gpe(). ACPICA BZ 1102. Lv Zheng.

ACPICA commit 1cf1a1e090f61f0c27f1dcf1905c7cc79a9c51c8
It is likely that we should synchronously invoke _REG(DISCONNECT) only when
the acpi_remove_address_space_handler() is invoked because of dependencies.
If it is invoked when the object is not referenced, problem may occur
if the operation region fields accessed in _REG are no longer driven by any
device driver.
Noticed that _REG(CONNECT)/_REG(DISCONNECT) only mean to inform the AML of
the handler availability, no return value is required for the caller.
This patch only introduces ACPI_REG_DISCONNECT invaocation, but doesn't
introduce a real change. Lv Zheng.

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.

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 change adds support to disassemble a UUID back to the original
ToUUID operator. It will detect a UUID within a standard AML Buffer.
Also, a description of the UUID is emitted for "known" UUIDs, defined
as UUIDs that are defined in the ACPI specification.
Since this is a change for disassembler which is not shipped in the
Linux kernel, the Linux kernel is not affected.

For _HID and _CID, the disassembler will emit a string that describes
the device if the _HID/_CID value is recognized. acpihelp updated also.
acpihelp will now search for a specific ID as well as displaying
the list of "known" (to ACPICA) IDs.
This patch does not affect Linux kernel behavior as the disassembler
and the acpihelp are not shipped with it.

Use push and pop to both guarantee that the correct alignment is used,
and to restore the alignment to whatever it was before the header
was included.
It is reported that the #pragma pack(push/pop) directives are not supported
by the specific GCCs, but this patch still doesn't affect kernel build
as there are already #pragma pack([1]) directives used in the old ACPICA
headers, which means there shouldn't be GCCs that are currently used to
compile the ACPI kernels do not support #pragma pack() directives.

This change adds full pathname support for external names that have been
resolved internally by the inclusion of additional ACPI tables (via the
iASL -e option). Without this change, the disassembler can emit multiple
externals for the same object, or it become confused when the Scope()
operator is used on an external object.
Linux kernel behaviour is not affected as the structure changes and the
new invocations are only used by compiler and disassembler which are
not shipped in the kernel currently.

This change adds and deploys "safe" versions of strcpy and strcat that
ensure that the target buffer does not overflow. These safe functions
are only helpful for processing user input and command lines. For most
ACPICA code however, the required buffer length is precisely calculated
before buffer allocation, so the use of these functions is unnecessary.
ACPICA BZ 1043.
This change only applies to the ACPICA utilities and the debugger, none
of which are not shipped with the kernel yet, so the kernel's behavior
remains unchanged after it.

This change adds support to allow hosts to install System Control
Interrupt handlers. Certain ACPI functionality requires the host
to handle raw SCIs. For example, the "SCI Doorbell" that is defined
for memory power state support requires the host device driver to
handle SCIs to examine if the doorbell has been activated. Multiple
SCI handlers can be installed to allow for future expansion.
Debugger support is included.
Lv Zheng, Bob Moore. ACPICA BZ 1032.
Bug summary:
It is reported when the PCC (Platform Communication Channel, via
MPST table, defined in ACPI specification 5.0) subchannel responds
to the host, it issues an SCI and the host must probe the subchannel
for channel status.

Add new API to allow OSPM to disable/enable specific types of _OSI
interface strings.
ACPICA does not have the knowledge about whether an _OSI interface
string is an OS vendor string or a feature group string and there
isn't any API interface to allow OSPM to install a new interface
string as a feature group string.
This patch simply adds all feature group strings defined by ACPI
specification into the acpi_default_supported_interfaces with
ACPI_OSI_FEATURE flag set to fix this gap. This patch also adds
codes to keep their default states as ACPI_OSI_INVALID before the
initialization and after the termination.
