* ACPICA: Add __init for ACPICA initializers/finalizers.Lv Zheng2013-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | This patch adds __init to the ACPICA documented initializers: acpi_initialize_tables() acpi_initialize_subsystem() acpi_load_tables() acpi_enable_subsystem() acpi_initialize_objects() and to acpi_reallocate_root_table(), acpi_find_root_pointer() which are also meant to be called only during initialization. This patch adds __init to the ACPICA documented finalizer: acpi_terminate() as this finalizer is only called in __init function now. This change helps to reduce source code differences between ACPICA upstream and Linux. [rjw: Changelog] Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

* ACPICA: Deploy ACPI_EXPORT_SYMBOL_INIT for main ACPICA initialization ↵Lv Zheng2013-10-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | interfaces. This changes can reduce source code differences between Linux and ACPICA upstream to help improving the release automation. The side effect of applying this patch in Linux is: 1. Some ACPICA initialization/termination APIs are no longer exported in Linux, these include: acpi_load_tables acpi_initialize_subsystem acpi_enable_subsystem acpi_initialize_objects acpi_terminate 2. This patch does not affect the following APIs as they are currently not marked with ACPI_EXPORT_SYMBOL in Linux: acpi_reallocate_root_table acpi_initialize_tables Such functions should not be exported as they are internal to ACPI subsystem in Linux, and will only be invoked inside of ACPI subsystem's initialization routines marked with __init and termination routines marked with __exit. While on other OSPMs, such functions may still need to be exported. Thus this patch adds the configurability for ACPICA, so that it leaves OSPMs to determine if the __init/__exit marked functions should be exported or not. Lv Zheng.

* ACPICA: Add EXPORT_ACPI_INTERFACES macro to external interface modules.Lv Zheng2013-10-311-1/+2
| | | | | | | | | | | | For Linux, there are no functional changes/binary generation differences introduced by this patch. This change adds a new macro to all files that contain external ACPICA interfaces. It can be detected and used by the host (via the host-specific header) for any special processing required for such modules. Lv Zheng.

* ACPICA: Add acpi_update_interfaces() public interfaceLv Zheng2013-07-231-0/+29
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* ACPICA: Cleanup source to reduce differences between Linux and ACPICA.Lv Zheng2013-01-101-4/+0
| | | | | | | | | | | | | | | | | | | This is a cosmetic patch only. Comparison of the resulting binary showed only line number differences. This patch does not affect the generation of the Linux binary. This patch decreases 389 lines of 20121018 divergence.diff. This patch reduces source code diff caused by the simple code maintenance work: 1. Deletion of the unused include files. 2. Deletion of the deprecated codes blocks. 3. Repositioning of the code blocks. 4. Replacing the values with the well defined macros. 5. Replacing the types with the equivalent types.

* ACPICA: Add support for complex _PLD buffers.Bob Moore2012-09-211-0/+87
| | | | | | | | | | | | | | | | | | | | _PLD (Physical Location of Device) returns a bit-packed buffer that is difficult to parse. This change adds a new interface, AcpiDecodePldBuffer that parses the buffer into a more usable local struct. Also adds macros to both get and set individual fields within the packed _PLD buffer. Adds a new include file, acbuffer.h - which will be expanded to add structs for other ACPI names that return buffers. ACPICA BZ 954. Emit (in comments) the decoded contents of a static _PLD buffer in order to improve comprehension of this bit-packed buffer. Add multi-endian support to the _PLD decode routine. Deploy the multi-endian macros to extract data from the _PLD buffer.

| * ACPI / ACPICA: Defer enabling of runtime GPEs (v3)Rafael J. Wysocki2010-09-241-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current ACPI GPEs initialization code has a problem that it enables some GPEs pointed to by device _PRW methods, generally intended for signaling wakeup events (system or device wakeup). These GPEs are then almost immediately disabled by the ACPI namespace scanning code with the help of acpi_gpe_can_wake(), but it would be better not to enable them at all until really necessary. Modify the initialization of GPEs so that the ones that have associated _Lxx or _Exx methods and are not pointed to by any _PRW methods will be enabled after the namespace scan is complete.

* | ACPICA/ACPI: Add new host interfaces for _OSI supportLin Ming2010-10-011-1/+124
|/ | | | | | | | | | | | | | | | | | | | Adds install/remove interfaces so that the host can dynamically alter the global _OSI table. Also adds support for _OSI handlers. Additional support: new debugger command (osi), and test support in the acpiexec utility. Adds new file, utilities/utosi.c. ACPICA bugzilla 836. The Linux OSL _OSI code is also changed. acpi_osi_setup can't call acpi_install/remove_interface because ACPICA is not initialized yet at this early time. So we just save the osi string in acpi_osi_setup and will handle it later in a new function acpi_osi_setup_late. http://www.acpica.org/bugzilla/show_bug.cgi?id=836 Signed-off-by: Lin Ming <ming.m.lin@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI / ACPICA: Do not execute _PRW methods during initializationRafael J. Wysocki2010-07-121-6/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, during initialization ACPICA walks the entire ACPI namespace in search of any device objects with assciated _PRW methods. All of the _PRW methods found are executed in the process to extract the GPE information returned by them, so that the GPEs in question can be marked as "able to wakeup" (more precisely, the ACPI_GPE_CAN_WAKE flag is set for them). The only purpose of this exercise is to avoid enabling the CAN_WAKE GPEs automatically, even if there are _Lxx/_Exx methods associated with them. However, it is both costly and unnecessary, because the host OS has to execute the _PRW methods anyway to check which devices can wake up the system from sleep states. Moreover, it then uses full information returned by _PRW, including the GPE information, so it can take care of disabling the GPEs if necessary. Remove the code that walks the namespace and executes _PRW from ACPICA and modify comments to reflect that change. Make acpi_bus_set_run_wake_flags() disable GPEs for wakeup devices so that they don't cause spurious wakeup events to be signaled. This not only reduces the complexity of the ACPICA initialization code, but in some cases it should reduce the kernel boot time as well. Unfortunately, for this purpose we need a new ACPICA function, acpi_gpe_can_wake(), to be called by the host OS in order to disable the GPEs that can wake up the system and were previously enabled by acpi_ev_initialize_gpe_block() or acpi_ev_update_gpes() (such a GPE should be disabled only once, because the initialization code enables it only once, but it may be pointed to by _PRW for multiple devices and that's why the additional function is necessary).
