* ACPICA: Debugger: Split debugger initialization/termination APIsLv Zheng2015-08-251-11/+0
| | | | | | | | | | | | | | | | | | | | ACPICA commit 7a3f22baab000b186779dac64ad71d9776b8f432 It is likely that the debugger is enabled only when a userspace program explicitly tells a kernel to do so, so it shouldn't be initialized as early as current implementation. The only tool requiring ACPI_DEBUGGER is acpiexec, so acpiexec need to call the new APIs by itself. And BSD developers may also get notified to invoke the APIs for DDB enabling. Lv Zheng. This patch doesn't affect Linux kernel as debugger is currently not enabled in the Linux kernel.

* ACPICA: Tables: Fix an issue that FACS initialization is performed twiceLv Zheng2015-07-011-4/+6
| | | | | | | | | | | | | | ACPICA commit 90f5332a15e9d9ba83831ca700b2b9f708274658 This patch adds a new FACS initialization flag for acpi_tb_initialize(). acpi_enable_subsystem() might be invoked several times in OS bootup process, and we don't want FACS initialization to be invoked twice.

* ACPICA: acpiexec: Add option to specify an object initialization file.Bob Moore2014-11-281-0/+11
| | | | | | | | | | | | | | This option (-fi) allows the specification of a file that is used to specify initialization values for individual namespace objects. Each line in the file is in the format: <ACPI pathname> <Integer Value> This patch only affects acpiexec which is not in the Linux kernel.

* ACPICA: Add __init for ACPICA initializers/finalizers.Lv Zheng2013-10-311-3/+3
| | | | | | | | | | | | | | | | | | | | | | 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 Zheng2013-10-311-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
