Replace C library macros such as ACPI_STRLEN with the standard names such as strlen. The original purpose for these macros is long since obsolete. Also cast various invocations as necessary.

* ACPICA: acpidump: Allow customized tables to be dumped without accessing ↵Lv Zheng2015-07-011-43/+46
| | | | | | | | | | | | | | | | | | /dev/mem ACPICA commit ab29013cfa2424140446aff196a70b211ab343a9 The /dev/mem can be configured out, in which case, acpidump should still work with "-c" option as tables can be found in /sys/firmware/acpi/tables. This patch allows acpidump to work without /dev/mem. This patch has been tested with "acpidump -c" and "acpidump -c -n FADT". And it worked as expected. Lv Zheng.

* 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: Add portable file IO to improve portabilityLv Zheng2014-07-081-0/+214
| | | | | | | | | | | | | | | | | 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.

* ACPICA: OSL: Clean up acpi_os_printf()/acpi_os_vprintf() stubsLv Zheng2014-07-081-0/+1304
| | | | | | | | | | | | | | | | | | | | | | | | 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: Tables: Add new mechanism to skip NULL entries in RSDT and XSDT.Lv Zheng2014-05-071-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is reported that there are buggy BIOSes in the world: AMI uses an XSDT compiler for early BIOSes, this compiler will generate XSDT with a NULL entry. 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.

* ACPICA: acpidump: Add support to force using RSDT.Lv Zheng2014-05-071-5/+27
| | | | | | | | | | | | | | | | | | | | | This patch adds "-x" and "-x -x" options to disable XSDT for acpidump. The single "-x" can be used to stop using XSDT, RSDT will be forced to find static tables, note that XSDT will still be dumped. The double "-x" can stop dumping XSDT, which is useful when the XSDT address reported by RSDP is pointing to an invalid address. It is reported there are platforms having broken XSDT shipped, acpidump will stop working while accessing such XSDT. This patch adds new option so that users can force acpidump to dump tables listed in the RSDT. Lv Zheng.

| | | | | | | | | | | This patch enforces a rule to always use ACPI_VALIDATE_RSDP_SIG for RSDP signatures passed from table header or ACPI_SIG_RSDP so that truncated string comparison can be avoided.

| | | | | | | | | | | | | | | | This patch fixes an issue that the while loop is not needed as fread() should return exact the bytes of expected. The patch is tested by runing diff against the output of "-c" mode and the normal mode, and only finds the following differences: 1. table addresses: the "-c" mode will always fill 0x0000000000000000 for the address. 2. RSDP/RSDT/XSDT: there is no generation of such tables for "-c" mode. So the test result shows the fix is valid. Lv Zheng.
