Notice that the bit_width, bit_offset and access_width fields in
struct acpi_generic_address are not used during GPE register
accesses any more, so introduce a simplified address structure
type, struct acpi_gpe_address, to represent addresses of GPE
registers and use it instead of struct acpi_generic_address in
struct acpi_gpe_register_info.

ACPICA commit 9605023e7e6d1f05581502766c8cf2905bcc03d9
This patch implements a new infinite loop detection mechanism to replace
the old one, it uses acpi_os_get_timer() to limit loop execution into a
determined time slice.
This is useful in case some hardware/firmware operations really require the
AML interpreter to wait while the old mechanism could expire too fast on
recent machines.
The new mechanism converts old acpi_gbl_max_loop_iterations to store the user
configurable value for the new mechanism in order to allow users to be
still able to configure this value for acpiexec via command line. This
patch also removes wrong initilization code of acpi_gbl_max_loop_iterations
accordingly (it should have been initialized by ACPI_INIT_GLOBAL, and the
default value is also properly tuned for acpiexec). Reported by M. Foronda,
fixed by Lv Zheng.

PinGroupConfig() is analogous to PinGroupFunction() but instead of mode
(muxing), it is used to apply specific fine-grained configuration to a

The format of this new resource is:

ResourceSource, ResourceSourceIndex, ResourceSourceLabel,
ResourceUsage, DescriptorName, VendorData)
The PinConfigType/PinConfigValue are the same used by PinConfig()
resource.
Here also the combination of ResourceSource and ResourceSourceLabel is
used to specify the PinGroup() this resource refers to.

ACPICA commit bd9a745749eac7137cd23085e6bdeb322de14ea2
PinGroupFunction() is a new resource introduced with ACPI 6.2. It is
used with PinGroup() to configure specific mode for a set of pins
exposed by a GPIO controller.
The format of the resource is:
PinGroupFunction (Shared/Exclusive, FunctionNumber, ResourceSource,
ResourceSourceIndex, ResourceSourceLabel,
ResourceUsage, DescriptorName, VendorData)
The resource_source and ResourceSourceLabel fields are used to specify
the PinGroup() resource referenced by PinGroupFunction().
Device (GPIO)
{
Name (_CRS, ResourceTemplate () {
PinGroup ("group1") {2, 3}
PinGroup ("group2") {4, 5}
...
})
}
Device (I2C)
{
Name (_CRS, ResourceTemplate () {
PinGroupFunction (Exclusive, 6, "^GPIO", 0, "mygroup2")
})
}
In the above example the PinGroupFunction() references the second
PinGroup() resource (using label "mygroup2" and configures pins 4 and 5
into mode 6.

ACPICA commit a06fdba686cefccd5dd5b93b52fa0f1e3f984906
ACPI 6.2 introduced a new resource that is used to specify fine-grained
configuration of a pin or set of pins used by a device. The ASL syntax of
this new resource looks like:
PinConfig (Shared/Exclusive, PinConfigType, PinConfigValue,
ResourceSource, ResourceSourceIndex, ResourceUsage,
DescriptorName, Vendordata) {Pin List}
PinConfigType is an integer with following accepted values:
0x00 (Default) - No configuration is applied to the pin
0x01 (Bias Pull-up) - Pin is pulled up using certain size resistor
0x02 (Bias Pull-down) - Pin is pulled down using certain size resistor
0x03 (Bias Default) - Set to default biasing
0x04 (Bias Disable) - All bias settings will be disabled
0x05 (Bias High Impedance) - Configure the pin as hi_z
0x06 (Bias Bus Hold) - Configure the pin in a weak latch state where
it drives the last value on a tristate bus
0x07 (Drive Open Drain) - Configure the pin into open drain state
0x08 (Drive Open Source) - Configure the pin into open source state
0x09 (Drive Push Pull) - Configure the pin into push-pull state
0x0a (Drive Strength) - How much the pin can supply current
0x0b (Slew Rate) - Configure slew rate of the pin
0x0c (Input Debounce) - Enable input debouncer for the pin
0x0d (Input Schmitt Trigger) - Enable schmitt trigger for the pin
0x0e - 0x7f - Reserved
0x80 - 0xff - Vendor defined types
The PinConfigValue depends on the type and is expressed as units
suitable for that type (for example bias uses Ohms).

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.

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.

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 6b2701f619040e803313363f516b200e362a9100
Make these mutex objects independent of the deadlock detection mechanism.
This mechanism caused failures with the multithread debugger.
This patch doesn't affect Linux kernel as debugger is currently not fully
functioning in the Linux kernel. And the further debugger cleanups will
take care of handling debugger command signalling correctly instead of
using such kind of mutexes. So it is safe to leave this patch as it is.

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 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 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.
