From 1b673f23d95f0bbc7e3c95321864b727ea75704b Mon Sep 17 00:00:00 2001 From: Tomasz Nowicki Date: Tue, 29 Oct 2013 09:28:49 +0800 Subject: ACPICA: Ensure that debug output is immediately disabled on termination. Set the global debug flag to "no output" when the debugger is shutdown. ACPICA BZ 1011. Tomasz Nowicki. Since the debugger is not shipped in the Linux kernel upstream, this change doesn't affect Linux kernel's behavior.

The original upstream ACPICA change added full history and limited line editing to the debugger: This change adds full history and limited line editing for Unix and Linux systems. It does not use readline() because of portability issues. Instead it uses the POSIX termio interface to put the terminal in raw input mode so that the various special keys can be trapped (such as up-arrow and down-arrow for history support). Since the debugger is not shipped in the kernel, it only is necessary to update one header file to keep the kernel source in sync with the upstream.

This change adds and deploys "safe" versions of strcpy and strcat that ensure that the target buffer does not overflow. These safe functions are only helpful for processing user input and command lines. For most ACPICA code however, the required buffer length is precisely calculated before buffer allocation, so the use of these functions is unnecessary. ACPICA BZ 1043. This change only applies to the ACPICA utilities and the debugger, none of which are not shipped with the kernel yet, so the kernel's behavior remains unchanged after it.

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.

During the automatic translation of the upstream ACPICA source code into Linux kernel source code some extra white spaces are added by the "indent" program at the beginning of each line which is an invocation of a macro and there is no ";" at the end of the line. For this reason, a new mode has been added to the translation scripts to remove the extra spaces inserted before invoking such macros and add an empty line between the invocations of such macros (like the other function declarations). This new mode is executed after executing "indent" during the Linux release process. Consequently, some existing ACPICA source code in the Linux kernel tree needs to be adjusted to allow the new scripts to work correctly. The affected macros and files are: 1. ACPI_HW_DEPENDENT_RETURN (acpixf.h/acdebug.h/acevents.h): This macro is used as a wrapper for hardware dependent APIs to offer a stub when the reduced hardware is configured during compilation. 2. ACPI_EXPORT_SYMBOL (utglobal.c): This macro is used by Linux to export symbols to be found by Linux modules. All such invocations are well formatted except those exported as global variables. This can help to reduce the source code differences between Linux and upstream ACPICA, and also help to automate the release process. No functional or binary generation changes should result from it.

The new ACPICA OSL override mechanism is used to solve these issues for the Linux OSL: 1. Linux can implement OSL using a macro. 2. Linux can implement OSL using an inlined function. 3. Linux can leave OSL not implemented for __KERNEL__ undefined code fragments. 4. Linux can add sparse declarators (__iomem) to OSL. 5. Linux can add memory tuning declarators (__init/__exit) to OSL. This patch also moves Linux specific OSL to aclinux.h which has not been maintained in the ACPICA code base. Lv Zheng. Known issue: From ACPICA's perspective, actypes.h should be included after inclusion of acenv.h. But currently in Linux, aclinux.h included by acenv.h has included actypes.h to find ACPICA types for inline functions. This is a known and existing issue and currently there is no real problem caused by this issue for Linux kernel build. Thus this issue is not covered by this cleanup commit.
