Add 2009 copyright to all module headers and signons, including the Linux
header. This affects virtually every file in the ACPICA core subsystem,
iASL compiler, and all utilities.
1) Decode all Boot Architecture flags.
2) Decode all flags, regardless of the FADT version. Previously,
only those flags that were actually valid for the FADT version
were displayed. This seemed to omit some information.
Previously, the table override mechanism was implemented for the
DSDT only. Now, any table in the RSDT/XSDT can be replaced by the
host OS. (including the DSDT).
This returns the FADT support to the original behavior, which is to
use default register widths. However, now check each register
definition and report a warning if it differs from the default.
This is a first step to moving away from the default widths, rather
than outright believing the widths in all FADTs for all machines,
considered rather dangerous until more data is obtained.
1) Update the register lengths for the PM1 event blocks. The length
must be divided by two in order to use these to access the status
registers.
2) Add run-time option to use default register lengths to override a
faulty FADT.
3) Add warning message if any of the X64 address structures contain a
length that does not match the legacy length earlier in the FADT.
4) Move all FADT warning messages into the ValidateFadt function.
1) Clear external list generated by Scope in external tables
2) Set node owner id only if it satisfies all the following conditions
a. Not a predefined node, _SB_ etc.
b. Not the root node
c. Not a node created by Scope
3) Precise object types for External statements, for example
- External (\_PR_.CPU0, DeviceObj)
+ External (\_PR_.CPU0, ProcessorObj)
Uses the FADT-defined reset register and reset value. Checks the
FADT flags for the reset register supported bit. Supports reset
register in memory or I/O space, but not in PCI config space since
the host has the information to do it.
Changed the HwLowLevelRead and HwLowLevelWrite functions to the public
AcpiRead and AcpiWrite to allow direct access to ACPI registers.
Removed the "width" parameter since the width can be obtained from the
input GAS structure. Updated the FADT initialization to setup the GAS
structures with the proper widths. Some widths are still hardcoded
because many FADTs have incorrect register lengths.
This function maps an input GPE index to a GPE block device. Also
Added AcpiCurrentGpeCount to track the current number of GPEs that
are being managed by the ACPICA core (both FADT-based GPEs and the GPEs
contained in GPE block devices.)
Previously did not allow the creation of named objects within a while
loop. However, it is not possible to analyze the loop to determine if
a named object would actually be created twice. Also, compiling
disassembled code with switch statements would raise this error even
though the compiler-emitted while(one) loop only executed once (there
is a break statement at the bottom of the loop. Chalk this one up to
'a nice try'.
For Windows compatibility, return an implicit integer of value
zero for methods that have no executable code. A default implicit
value of zero is provided for methods.
Such methods are seen in the field as stubs (presumably), and can
cause drivers to fail if they expect a return value. Lin Ming.
Merge the code that validates control method argument counts into
the predefined validation module. Eliminates possible multiple
warnings for incorrect counts.
This can happen if the _WAK method returns nothing (as per ACPI 1.0)
but does return an integer if the implicit return mechanism is enabled.
This is the only method that has this problem, since it is also
defined to return a package of two integers (ACPI 1.0b+). In all
other cases, if a method returns an object when one was not expected,
no warning is issued.
For predefined methods (such as _BIF), add automatic conversion for
objects that are required to be a String, but a Buffer was found
instead. This can happen when reading string battery data from
an operation region, because it used to be difficult to convert
the data from buffer to string from within the ASL. Linux BZ 11822.
In a fully qualified namepath, allow multiple backslash prefixes.
This can happen because of the use of a double-backslash in
strings (since backslash is the escape character) causing confusion.
ACPICA BZ 739 Lin Ming.
Moved some commonly-used defines and global variables from the
private headers to the public headers. Split the resource descriptor
structs out of actypes.h to a new file, acrestyp.h
Fixes a problem where the use of an alias within a namepath would
result in a not found error or cause the compiler to fault.
Also now allows forward references from the Alias operator itself.
ACPICA BZ 738.
Added the -e option to allow the inclusion of additional ACPI tables
to help with the disassembly of method invocations and the generation
of external declarations during the disassembly. Certain external
method invocations cannot be disassembled properly without the actual
declaration of the method. Use the -e option to include the table
where the external method(s) are actually declared. Most useful for
disassembling SSDTs that make method calls back to the master DSDT.
Lin Ming.
Example: To disassemble an SSDT with calls to DSDT:
iasl -d -e dsdt.aml ssdt1.aml
The current implemenation of _OSI within ACPICA only allows other
control methods to execute _OSI. This change allows the host OS
to execute _OSI via the AcpiEvaluateObject interface. _OSI is a
special method -- it does not exist in the AML code, it is
implemented within ACPICA.
acpi.h now includes only the "public" acpica headers. All other
acpica headers are "private" and should not be included by acpica
users. One new file, accommon.h is used to include the commonly
used private headers for acpica code generation. Future plans are
to move all private headers to a new subdirectory.
