This feature is optional and is enabled if the BIOS requests any Windows
OSI strings. It can also be enabled by the host OS. Matthew Garrett,
Bob Moore.
Adds a reference count mechanism to simplify support of shared GPEs that
require multiple device drivers. Several external interfaces have changed.
One external interface has been removed.
Changed:
AcpiEnableGpe
AcpiDisableGpe
AcpiClearGpe
AcpiGetGpeStatus
Removed:
AcpiSetGpeType
New:
AcpiSetGpe
See the ACPICA Programmer Reference for details.

Optionally copy the entire DSDT to local memory (instead of simply
mapping it.) There are some BIOSs that corrupt or replace the original
DSDT, creating the need for this option. Default is FALSE, do not copy
the DSDT.
This change will enable debug object output via a global variable,
AcpiGbl_EnableAmlDebugObject. This will help with remote machine
debugging. Also, moved all debug object support code to a new file,
executer/exdebug.c. Entire debug object module can now be configured
out of the ACPICA build if desired. Lin Ming, Bob Moore.
Add 2010 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.
The existing interface only has a pre-order callback. This change
adds an additional parameter for a post-order callback which will
be more useful for bus scans. ACPICA BZ 779. Lin Ming.
Completed a major update for the AcpiGetObjectInfo external interface.
Changes include:
- Support for variable, unlimited length HID, UID, and CID strings
- Support Processor objects the same as Devices (HID,UID,CID,ADR,STA, etc.)
- Call the _SxW power methods on behalf of a device object
- Determine if a device is a PCI root bridge
- Change the ACPI_BUFFER parameter to ACPI_DEVICE_INFO.
These changes will require an update to all callers of this interface.

Needed by drivers for new ACPi tables.
Internal versions of these functions still use 32-bit max transfers,
in order to minimize disruption and stack use for the standard ACPI
registers (FADT-based).
Removed locking for reads from the ACPI bit registers in PM1 Status,
Enable, Control, and PM2 Control. The lock is not required when
reading the single-bit registers. The AcpiGetRegisterUnlocked function
is no longer needed and has been removed. This will improve performance
for reads on these registers.
ACPICA BZ 760.
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.
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.)
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
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.
Split AcpiSetFirmwareWakingVector into two: one for the 32-bit vector,
another for the 64-bit vector. This is required because the host OS must
setup the wake much differently for each vector (real vs. protected mode,
etc.) and the interface should not be deciding which vector to use.
Also eliminate the GetFirmwareWakingVector interface, as it served no
purpose (only the firmware reads the vector, OS only writes the vector.)
ACPICA BZ 731.
Added 2008 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities.
Designed and implemented new external interfaces to install and remove handlers for ACPI table-related events. Current events that are defined are LOAD and UNLOAD. These interfaces allow the host to track ACPI tables as they are dynamically loaded and unloaded. See AcpiInstallTableHandler and AcpiRemoveTableHandler. (Lin Ming and Bob Moore)
Added 2007 copyright to all module headers and signons. This affects virtually every file in the ACPICA core subsystem, iASL compiler, and the utilities.
The Flags parameter for AcpiGetRegister and AcpiSetRegister has been removed. It is no longer necessary now that these functions use a spinlock for mutual exclusion.
