The bug can be reproduced by using a format that do not have the width.prec specified after a format that have the width.prec specified. The second formatted output will be wrong. The root cause is acpi_ut_vsnprintf() doesn't reset the specifiers to the default values. This patch fixes this issue. BZ 1094. Reported by Yizhe Wang, fixed by Lv Zheng. Since acpi_ut_vprintf() is only enabled for specific OSPM now, this patch doesn't affect Linux kernel. Link: https://bugs.acpica.org/show_bug.cgi?id=1094Reported-and-tested-by:

This change adds support to disassemble a UUID back to the original ToUUID operator. It will detect a UUID within a standard AML Buffer. Also, a description of the UUID is emitted for "known" UUIDs, defined as UUIDs that are defined in the ACPI specification. Since this is a change for disassembler which is not shipped in the Linux kernel, the Linux kernel is not affected. Signed-off-by:

ACPICA commit c49dbfed2bc069d0038ea7e1294409bfde7c2c8c Some potential callers of acpi_setup_gpe_for_wake may know in advance that there won't be any notify handlers installed for device wake notifications from the given GPE (one example is a button GPE in Linux). For these cases, acpi_mark_gpe_for_wake should be used instead of acpi_setup_gpe_for_wake. This will set the ACPI_GPE_CAN_WAKE flag for the GPE without trying to setup implicit wake notification for it (since there's no handler method). Rafael Wysocki. Signed-off-by:

ACPICA commit 23b5a8542283af28c3a3a4e3f81096d6e2569faa There is no point in enabling a GPE that has no handler or GPE method. At worst, it can cause GPE floods. Rafael Wysocki. Signed-off-by:

Fixes a regression introduced by commit e23d9b82 (ACPICA: Namespace: Properly null terminate objects detached from a namespace node) In the case of Alias namespace nodes, the node simply points to the aliased node via the Object field; thus we cannot assume that the object is an operand object.

This patch reduces the requirement of invoking freopen() in acpidump in order to reduce the porting effort of acpidump. This patch achieves this by turning all acpi_os_printf(stdout) into acpi_ut_file_printf(gbl_output_file). Lv Zheng. Signed-off-by:

The new APIs are enabled to offer a portable layer to access files: 1. acpi_os_XXX_file_XXX: Wrapper of fopen/fclose/fread/fwrite 2. acpi_os_printf: Wrapper of printf 3. acpi_log_error: Wrapper of fprintf(stderr) This patch deploys such mechanisms to acpidump to improve the portability of this tool.

This patch uses abstract file IO and acpi_log_error() APIs to enhance cm_get_file_size() so that applications that invoke this API could have portability improved. With actual references added to abstract file IO and acpi_log_error(), the applications need to link oslibcfs.o, utdebug.o, utexcep.o, utmath.o, utprint.o and utxferror.o. It is also required to add acpi_os_initialize() invocations if an application starts to use acpi_log_error(). acpidump has already invoked acpi_os_initialize() in this way. Lv Zheng. Signed-off-by:

ACPICA: Application: Enhance ACPI_USAGE_xxx/ACPI_OPTION with 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.

Invocations like fprintf(stderr) and perror() are not portable, this patch introduces acpi_log_error() as a replacement, it is implemented using new portable API - acpi_ut_file_vprintf(). Note that though acpi_os_initialize() need to be invoked prior than using this new API, since no users are introduced in this patch, such invocations are not added for applications that link utprint.c in this patch. Futher patches that introduce users of acpi_log_error() should take care of this. This patch is only useful for ACPICA applications, most of which are not shipped in the Linux kernel. Note that follow-up commits will update acpidump to use this new API to improve portability. Lv Zheng. Signed-off-by:

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. Signed-off-by: -

This patch adds portable file IO to generic OSL to improve the portability of the applications. A portable application may use different file IO interfaces than the standard C library ones. This patch thus introduces an abstract file IO layer into the generic OSL. Note that this patch does not introduce users of such interfaces, further patches should introduce users one by one carefully with build tests performed. Lv Zheng. Signed-off-by:

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.

ACPICA: Utilities: Cleanup DEFINE_ACPI_GLOBALS by moving acpi_ut_init_global() from utglobal.c to utinit.c The utglobal.c is used to define and initialize global variables. 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. Signed-off-by:

Implement proper RSDP validation in acpi_ut_read_table(). Prevents a segmentation fault that can occur if a user passes the wrong file to iasl. This patch is only useful for iasl, which is not shipped in the Linux kernel. After the new table reading utility functions are well tested, acpidump can also switch to use the generic acpi_ut_read_table_xxx() APIs. Currently this patch is no-op as acpidump does not link to the new APIs. Signed-off-by:

An error was found in the ACPICA provided non-native ACPI_IS_PRINT() causing the following difference with the native isprint() implementation: The GNU libc isprint('\n') test result: isprint(0x20) is FALSE The Linux kernel isprint('\n') test result: ACPI: isprint(0x20) is FALSE The _acpi_ctype isprint('\n') test result: isprint(0x20) is TRUE The ACPI_IS_PRINT() macro generated for _acpi_ctype is wrong. It should use _ACPI_XS instead of _ACPI_SP. _ACPI_XS is white space only. Other space characters should be non printable. This patch fixes this issue. For OSPMs that are using native standard isprint() implementations, this patch is a no-op. Lv Zheng. Signed-off-by: -
