ACPICA commit 4b0e043386c7e698bea9e862f60a388647f56622
Previously, there was a mixup where _NIG required one parameter and
_NIH required zero parameters. This changes swaps these parameter
requirements. Now this change requires _NIH to be called with one
parameter and _NIG requires zero.

ACPICA commit cd66d0a50fdc9cc4dcd998e08e7aa3c4154bea2d
Disassembler is intended to emit existing ASL code as-is. Therefore,
error messages emitted during disassembly should be ignored or
handled in a way such that the disassembler can continue to parse the
AML. This change ignores AE_ALREADY_EXISTS errors during the deferred
Op parsing for create operators in order to complete parsing ASL
termlists.

The check carried out by acpi_any_gpe_status_set() is not precise enough
for the suspend-to-idle implementation in Linux and in some cases it is
necessary make it skip one GPE (specifically, the EC GPE) from the check
to prevent a race condition leading to a premature system resume from
occurring.
For this reason, redefine acpi_any_gpe_status_set() to take the number
of a GPE to skip as an argument.

Fix this issue by checking the fixed events in acpi_s2idle_wake() in
addition to checking wakeup GPEs and break out of the suspend-to-idle
loop if the status bits of any enabled fixed events are set then.

ACPICA commit 9383f5b01091e432c05f802a57edc20d329eec1f
Hibernation (S4) is triggered in a guest when it recieves a sleep
trigger from the hypervisor. When the guest resumes from this power
state, it does not see the sleep_enabled bit. In otherwords, the sleep
button is not enabled on waking from an S4 state. This causes
subsequent invocation of sleep state to fail in the guest.
Fix this problem by enabling the sleep button in ACPI legacy wake.

ACPICA commit 79a466b64e6af36cc83102f05915e56cb7dd89ab
According to table 19-419 of the ACPI 6.3 specification, buffer_fields
created using the ASL create_field() Operator have been treated as
integers if the buffer_field is small enough to fit inside of an ASL
integer (32-bits or 64-bits depending on the definition block
revision). If they are larger, buffer fields are treated as ASL
Buffer objects. However, this is not true for other AML interpreter
implementations.
It has been discovered that other AML interpreters always treat
buffer fields created by create_field() as a buffer regardless of the
length of the buffer field.
More specifically, the Microsoft AML interpreter always treats buffer
fields created by the create_field() operator as buffer. ACPICA
currently does this only when the field size is larger than the
maximum integer width. This causes problems with AML code shipped in
Microsoft Surface devices.
More details:
The control methods in these devices determine the success of an ASL
control method execution by examining the type resulting from storing
a buffer field created by a create_field() operator. On success, a
Buffer object is expected, on failure an Integer containing an error
code. This buffer object is created with a dynamic size via the
create_field() operator. Due to the difference in behavior, Buffer
values of small size are however converted to Integers and thus
interpreted by the control method as having failed, whereas in
reality it succeeded. Below is an example of a control method called
TEST that illustrates this behavior.
Method (CBUF) // Create a Buffer field
{
/*
* Depending on the value of RAND, ACPICA interpreter will treat
* BF00 as an integer or buffer.
*/
create_field (BUFF, 0, RAND, BF00)
return (BF00)
}
Method (TEST)
{
/*
* Storing the value returned by CBUF to local0 will result in
* implicit type conversion outlined in the ACPI specification.
*
* ACPICA will treat local0 like an ASL integer if RAND is less
* than or equal to 64 or 32 (depending on the definition_block
* revision). If RAND is greater, it will be treated like an ASL
* buffer. Other implementations treat local0 like an ASL buffer
* regardless of the value of RAND.
*/
local0 = CBUF()
/*
* object_type of 0x03 represents an ASL Buffer
*/
if (object_type (Local0) != 0x03)
{
// Error on ACPICA if RAND is small enough
}
else
{
/*
* Success on APICA if RAND is large enough
* Other implementations always take this path because local0
* is always treated as a buffer.
*/
}
}
This change prohibits the previously mentioned integer conversion to
match other AML interpreter implementations (Microsoft) that do not
conform to the ACPI specification.

ACPICA commit 29cc8dbc5463a93625bed87d7550a8bed8913bf4
create_buffer_field is a deferred op that is typically processed in
load pass 2. However, disassembly of control method contents walk the
parse tree with ACPI_PARSE_LOAD_PASS1 and AML_CREATE operators are
processed in a later walk. This is a problem when there is a control
method that has the same name as the AML_CREATE object. In this case,
any use of the name segment will be detected as a method call rather
than a reference to a buffer field. If this is detected as a method
call, it can result in a mal-formed parse tree if the control methods
have parameters.
This change in processing AML_CREATE ops earlier solves this issue by
inserting the named object in the ACPI namespace so that references
to this name would be detected as a name string rather than a method
call.

ACPICA commit 367b363edc5fa1f93bbc14e4a1e05f34fef765a2
acpiexec allows a user to provide a file that indicates values to
initialize named objects during table load with the -fi option. This
can provide more accurate simulation by setting named objects to
values found during OS runtime.
Previously, this option only supported integer objects. This change
adds user initialization support for field units, strings, buffers,
and packages.

ACPICA commit d509afa88e9415f13a3283c38ce9ee034634ae24
Since field unit data output from the debugger are now surrounded by
braces '{', support has been added to acpi_db_get_next_token to recognize
strings beginning with this character as a ACPI_TYPE_FIELD_UNIT.

ACPICA commit 76ca57291d007d33087982a4b28cd1ee9bcd37a6
This helps differentiate the type of named objects between field
units and buffers. In other words, without this symbol, it would be
difficult to tell whether a particular named object is a buffer or a
field unit.

ACPICA commit d1716a829d19be23277d9157c575a03b9abb7457
For unloading an ACPI table, it is necessary to provide the index of
the table. The method intended for dynamically loading or hotplug
addition of tables, acpi_load_table(), should provide this information
via an optional pointer to the loaded table index.
This patch fixes the table unload function of acpi_configfs.
