* ACPICA: Clib: Eliminate acpi_os_XXXFile()/acpi_log_error and link clibrary ↵Lv Zheng2016-08-137-295/+81
| | | | | | | | | | | | | | | | | fxxx()/errno/perror() instead ACPICA commit 189429fb7d06cdb89043ae32d615faf553467f1d This patch follows new ACPICA design, eliminates old portable OSLs, and implements fopen/fread/fwrite/fclose/fseek/ftell for GNU EFI environment. This patch also eliminates acpi_log_error(), convering them into fprintf(stderr)/perror(). Lv Zheng.

* ACPICA: Clib: Add -nostdinc support for EFI layerLv Zheng2016-08-132-5/+4
| | | | | | | | | | | | | | | | | | | | | | | ACPICA commit d261d40ea168f8e4c4e3986de720b8651c4aba1c This patch adds sprintf()/snprintf()/vsnprintf()/printf()/vfprintf() support for OSPMs that have ACPI_USE_SYSTEM_CLIBRARY defined but do not have ACPI_USE_STANDARD_HEADERS defined. -iwithprefix include is required to include <stdarg.h> which contains compiler specific implementation of vargs when -nostdinc is specified. -fno-builtin is required for GCC to avoid optimization performed printf(). This optimization cannot be automatically disabled by specifying -nostdlib. Please refer to the first link below for the details. However, the build option changes do not affect Linux kernel builds and are not included. Lv Zheng.

* ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issueLv Zheng2016-08-133-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | ACPICA commit 9bb265c2afb9910e46f820d6759648580edabd09 When /Za is specified, headers of some Windows SDKs contain bugs breaking VC builds, and MSVC9's default SDK is one of such header-buggy library. In order to solve this issue, many VC developers stop using /Za. However we've been asked to have this fixed without removing /Za. In MSVC9 default SDK, this issue can be fixed by restricting <sys/stat.h> to be the last standard file included by every source file in the projects. This patch thus moves <sys/stat.h> inclusion to "acapps.h", so that this issue can be fixed by ensuring that "acapps.h" is always the last standard file included by all of the ACPICA source files. This is in fact also a useful cleanup because applications can only include one header (e.x., acpidump.h) instead of including acapps.h separately. Lv Zheng. Except some harmless header inclusion re-ordering, Linux kernel is not affected by this change.

* ACPICA: Clib/EFI: Fix wrong order of standard integer types/IO handlesLv Zheng2016-08-132-6/+0
| | | | | | | | | | | | | | | | | | | | | | | ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d EFI header should use standard C library stuffs (integer types and IO handles) rather than implementing such standard stuffs. This patch fixes this issue by: 1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n; 2. Defining EFI types using standard integer types and standard IO handles; 3. Tuning header inclusion order and environment definition order; 4. Removing wrong standard header inclusion from ACPICA core files; 5. Moving several application headers from acpidump.h to acenv.h. This patch corrects some of them. Lv Zheng. Except some harmless header inclusion re-ordering, Linux kernel is not affected by this change.

* ACPICA: OSL: Add correct acpi_gbl_debug_timeout export to allow acpiexec to linkLv Zheng2016-08-131-3/+0
| | | | | | | | | | | | | | | | | ACPICA commit 408198c8c9786f9f104ee925020c3ab1701906e4 The acpi_gbl_debug_timeout which is used by acpiexec -et option now is only implemented in oswinxf.c and used for WIN32 builds.

This solution doesn't cover function types. Note that the linuxize result of this commit is very giant and should have many conflicts against the current Linux upstream. Thus it is required to modify the linuxize result of this commit and the commits around it manually in order to have them merged to the Linux upstream. Since this is very costy, we should do this only once, and if we can't ensure to do this only once, we need to revert the Linux code to the wrong indentation result before merging the linuxize result of this commit.

* tools/power/acpi: Add userspace AML interface supportLv Zheng2015-12-153-8/+473
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a userspace tool to access Linux kernel AML debugger interface. Tow modes are supported by this tool: 1. Interactive: Users are able to launch a debugging shell to talk with in-kernel AML debugger. Note that it's user duty to ensure kernel runtime integrity by using this debugging tool: A. Some control methods evaluated by the users may result in kernel panics if those control methods shouldn't be evaluated by the OSPMs according to the current BIOS/OS configurations. B. Currently if a single stepping evaluation couldn't run to an end, then the synchronization primitives acquired by the evaluation may block normal OSPM control method evaluations. 2. Batch: Users are able to execute debugger commands in a script. Note that in addition to the above duties, it's user duty to ensure script runtime integrity by using this debugging tool in this mode: C. Currently only those commands that are not used for single stepping are suitable to be used in this mode. D. If the execution of the command may cause a failure that could result in an endless kernel execution, the execution of the script may also get blocked. To exit the utility, currently "exit/quit" commands are recommended, but ctrl-C" can also be used. Signed-off-by: Lv Zheng <lv.zheng@intel.com> Signed-off-by: Rafael J.

| | | | | | | | | | | | | | | | | | | | | | | | | | acpi_os_printf() to improve portability This patch enhances ACPI_USAGE_xxx/ACPI_OPTION macros to use portable acpi_os_printf() so that usage functions for applications no longer rely on the printf() API. To use acpi_os_printf() exported by osunixxf.c as a replacement of printf(), applications need to initialize acpi_gbl_output_file to stdout and initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT. The latter is automatically done by ACPI_INIT_GLOBAL(), applications need to link utglobal.o to utilize this mechanism. For GCC, assigning stdout to acpi_gbl_output_file using ACPI_INIT_GLOBAL() is not possible as stdout is not a constant in GCC environment. As an alternative solution, stdout assignment has been put into acpi_os_initialize(). Thus acpi_os_initialize() need to be invoked very early by the applications to initialize the default output of acpi_os_printf() to keep behavior consistency. acpidump has already invoked acpi_os_initialize() in this way.

* ACPICA: Utilities: Add formatted printing APIsLv Zheng2014-07-081-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces formatted printing APIs to handle ACPICA specific formatted print requirements. Currently only specific OSPMs will use this customized printing support, Linux kernel doesn't use these APIs at this time. It will be enabled for Linux kernel resident ACPICA after being well tested. So currently this patch is a no-op. The specific formatted printing APIs are useful to ACPICA as: 1. Some portable applications do not link standard C library, so they cannot use standard formatted print APIs directly. 2. Platform specific printing format may differ and thus not portable, for example, u64 is %ull for Linux kernel and is %uI64 for some MSVC versions. 3. Platform specific printing format may conflict with ACPICA's usages while it is not possible for ACPICA developers to test their code for all platforms. For example, developers may generate %pRxxx while Linux kernel treats %pR as structured resource printing and decodes variable argument as a "struct resource" pointer. This patch solves above issues by introducing the new APIs. Note that users of such APIs are not introduced in this patch. Users of acpi_os_file_vprintf()/acpi_ut_file_printf() need to invoke acpi_os_initialize(), this should be taken care by the further patches where such users are introduced. Lv Zheng.

* ACPICA: OSL: Clean up acpi_os_printf()/acpi_os_vprintf() stubsLv Zheng2014-07-084-22/+1306
| | | | | | | | | | | | | | | | | | | | | | | | This patch is mainly for acpidump where there are redundant acpi_os_printf()/acpi_os_vprintf() stubs implemented. This patch cleans up such specific implementation by linking acpidump to osunixxf.c/oswinxf.c. To make acpi_os_printf() exported by osunixxf.c/oswinxf.c to behave as the old acpidump specific ones, applications need to: 1. Initialize acpi_gbl_db_output_flags to ACPI_DB_CONSOLE_OUTPUT. This is automatically done by ACPI_INIT_GLOBAL(), applications need to link utglobal.o to utilize this mechanism. 2. Initialize acpi_gbl_output_file to stdout. For GCC, assigning stdout to acpi_gbl_output_file using ACPI_INIT_GLOBAL() is not possible as stdout is not a constant in GCC environment. As an alternative solution, stdout assignment is put into acpi_os_initialize(). Thus acpi_os_initialize() need to be invoked very early by the applications to initialize the default output of acpi_os_printf(). This patch also releases osunixxf.c to the Linux kernel. Lv Zheng.

It makes sense if just adding utglobal.o to applications that are using such variables. But acpi_ut_init_globals() is preventing us from doing so as this initialization function references other components' initializations code, which leads to the requirement that many files should also get linked if one wants to link utglobal.o. It is possible to just move acpi_ut_init_global() to utinit.c for applications that require this function to link. By linking utglobal.o, we can stop defining DEFINE_ACPI_GLOBALS for applications (currently only acpidump is affected). Lv Zheng.

The affected BIOS versions are "AMI BIOS F2-F4". Original solution on Linux is to use an alternative heathy root table instead of the ill one. This commit is: Commit: 671cc68dc61f029d44b43a681356078e02d8dab8 Subject: ACPICA: Back port and refine validation of the XSDT root table. This is an example of such XSDT dumped from B85-HD3 (AMI F3 BIOS): [000h 0000 4] Signature : "XSDT" [Extended System Description Table] [004h 0004 4] Table Length : 00000074 [008h 0008 1] Revision : 01 [009h 0009 1] Checksum : 18 [00Ah 0010 6] Oem ID : "ALASKA" [010h 0016 8] Oem Table ID : "A M I" [018h 0024 4] Oem Revision : 01072009 [01Ch 0028 4] Asl Compiler ID : "AMI " [020h 0032 4] Asl Compiler Revision : 00010013 [024h 0036 8] ACPI Table Address 0 : 00000000BA5F8180 [02Ch 0044 8] ACPI Table Address 1 : 00000000BA5F8290 [034h 0052 8] ACPI Table Address 2 : 00000000BA5F8308 [03Ch 0060 8] ACPI Table Address 3 : 00000000BA5F8848 [044h 0068 8] ACPI Table Address 4 : 00000000BA5F9320 [04Ch 0076 8] ACPI Table Address 5 : 00000000BA5F9360 [054h 0084 8] ACPI Table Address 6 : 00000000BA5F9398 [05Ch 0092 8] ACPI Table Address 7 : 00000000BA5F9708 [064h d100 8] ACPI Table Address 8 : 00000000BA5FC9A8 [06Ch 0108 8] ACPI Table Address 9 : 0000000000000000 But according to the bug report, the XSDT in fact is not broken. In the above XSDT, ACPI Table Address 1-8 contains the same value as RSDT. The differences can only be seen on the following 2 entries: 1. The first entry points to a FADT whose Revision is 5 while the first entry in RSDT points to a FADT whose Revision is 2. The FADT dumped from the address indicated by the first entry of XSDT: FACP @ 0x00000000BA5F8180 0000: 46 41 43 50 0C 01 00 00<05>4B 41 4C 41 53 4B 41 FACP.....KALASKA ... The FADT dumped from the address indicated by the first entry of RSDT: FACP @ 0x00000000BA5ED0F0 0000: 46 41 43 50 84 00 00 00<02>A7 41 4C 41 53 4B 41 FACP......ALASKA ... 2. The last entry is a NULL terminator. According to the test result, the Revision 5 FADT is accessible. Thus the original solution turns out to be a work around that is preventing the higher revision tables to be used for such platforms (they are all x86-64 platforms, and should use XSDT and higher revision FADT). This patch offers a new solution, where a sanity check is performed before installing a table address from XSDT. If the entry is NULL, it is simply discarded. Note that, this patch doesn't remove the original solution, so for Linux kernel, this commit is actually a no-op, but it allows acpidump to be working on such platforms. By doing so, we allow another easy revertable commit to enable this feature so that when that commit is reverted, the useful sanity check will not be affected. Lv Zheng.
