* ACPICA: Use uintptr_t and offsetof() in Linux kernel buildsRafael J. Wysocki2022-01-251-0/+5
| | | | | | | | | | | | | To avoid "performing pointer subtraction with a null pointer has undefined behavior" compiler warnings, use uintptr_t and offsetof() that are always available during Linux kernel builds to define acpi_uintptr_t and the ACPI_TO_INTEGER() and ACPI_OFFSET() macros. Based on earlier proposal from Arnd Bergmann. Link: https://lore.kernel.org/linux-acpi/20210927121338.938994-1-arnd@kernel.org Signed-off-by: Rafael J.

| | | | | | | | | | | The ACPI_USE_BUILTIN_STDARG symbol is never set in the kernel build, so stop checking it in include/acpi/platform/acgcc.h and drop all of the macros depending on it (which appear to duplicate the analogous macros from linux/stdarg.h, but in fact are never used).

Clang also supports this warning and statement attribute, but not the comment form. Robert Moore provides additional context about the lint comments being removed. They were for "an old version of PC-Lint, which we don't use anymore." Drop those. This will help us enable -Wimplicit-fallthrough throughout the Linux kernel.

The 2 APIs are used by Linux as table management APIs for long time, it contains a hidden logic that during the early stage, the mapped tables should be unmapped before the early stage ends. During the early stage, tables are handled by the following sequence: acpi_get_table_with_size(); parse the table early_acpi_os_unmap_memory(); During the late stage, tables are handled by the following sequence: acpi_get_table(); parse the table Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the late stage. The reasoning of introducing acpi_get_table_with_size() is: ACPICA will remember the early mapped pointer in acpi_get_table() and Linux isn't able to prevent ACPICA from using the wrong early mapped pointer during the late stage as there is no API provided from ACPICA to be an inverse of acpi_get_table() to forget the early mapped pointer. But how ACPICA can work with the early/late stage requirement? Inside of ACPICA, tables are ensured to be remained in "INSTALLED" state during the early stage, and they are carefully not transitioned to "VALIDATED" state until the late stage. So the same logic is in fact implemented inside of ACPICA in a different way. The gap is only that the feature is not provided to the OSPMs in an accessible external API style. It then is possible to fix the gap by providing an inverse of acpi_get_table() from ACPICA, so that the two Linux sequences can be combined: acpi_get_table(); parse the table acpi_put_table(); In order to work easier with the current Linux code, acpi_get_table() and acpi_put_table() is implemented in a usage counting based style: 1. When the usage count of the table is increased from 0 to 1, table is mapped and .Pointer is set with the mapping address (VALIDATED); 2. When the usage count of the table is decreased from 1 to 0, .Pointer is unset and the mapping address is unmapped (INVALIDATED). So that we can deploy the new APIs to Linux with minimal effort by just invoking acpi_get_table() in acpi_get_table_with_size() and invoking acpi_put_table() in early_acpi_os_unmap_memory().

* ACPICA: OSL: Fix a regression that old GCC requires a workaround for strchr()Lv Zheng2016-08-133-12/+62
| | | | | | | | | | | | | | | | | | | ACPICA commit be836c36454a624a4fb1d17234080ef8c07993fc There is a GCC false-warning issue on specific GCC versions that "strchr" will be preprocessed and extracted to contain !__buildin_constant_p() checker and it surely is a constant logical value "1" for strchr() arguments. Then -Wlogical-op errorneously reports a warning. The regression is triggered after the standard headers are re-ordered in the EFI porting task. This patch fixes this regression by moving the workaround to a new position after including all other standard headers.

* ACPICA: OSL: Cleanup the inclusion order of the compiler-specific headersLv Zheng2016-08-133-8/+17
| | | | | | | | | | | | | | | | | | | | | | | ACPICA commit a760a98ec84b1ec782e0bff5f6612af6fb89c10c Originally compiler specific headers are included by the host-specific headers. This makes build configuration management very inconvenient. And many inclusion order issues can be hidden accross different host OSes. It will then likely that some host builds will be broken just because of fixing some inclusion order issues for other host builds. This patch splits the compiler-specific header inclusions out of the host-specific headers so that compiler-specific inclusion order issues will not get entangled in the host-specific inclusion orders. Note that intel compiler defines __GNUC__, so this patch contains special handling because acintel.h and acgcc.h should be mutual exclusive.

* ACPICA: MSVC9: Fix <sys/stat.h> inclusion order issueLv Zheng2016-08-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.

The only user should be the EFI applications: ACPI_USE_SYSTEM_CLIBRARY=n ACPI_USE_STANDARD_HEADERS=n All other applications uses the compiler specific library: ACPI_USE_SYSTEM_CLIBRARY=y ACPI_USE_STANDARD_HEADERS=y Linux/BSD kernels are the kind of hosts providing C library but does not provide the standard headers: ACPI_USE_SYSTEM_CLIBRARY=y ACPI_USE_STANDARD_HEADERS=n But the above logic hasn't been synchronized between the header files. This patch synchronizes all header files to correct C library usages for different platforms. This patch moves all ACPI_USE_SYSTEM_CLIRARY and ACPI_USE_STANDARD_HEADERS to the top most lines of a platform specific header. After synchronization, ACPI_USE_SYSTEM_CLIRARY definition can be removed for ACPI_APPLICATION. Lv Zheng.
