ACPICA commit 47d22a738d0e19fd241ffe4e3e9d4e198e4afc69

Across all of ACPICA. 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. Bob Moore, Jung-uk Kim, Lv Zheng.

ACPICA commit 04c3bd7e9d6aeb2b3edebe99c90dc271ae4e6353

In order to work without any additional option to dump tables when /dev/mem
doesn't exist, this patch switches the default behavior of acpidump to dump
from /sys/firmware/acpi/tables. Reported by Al Stone, Fixed by Lv Zheng.

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".

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().

Lv Zheng d9cf147dbd 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. Lv Zheng.

Lv Zheng 80a648c12e ACPICA: Utilities: Add formatted printing APIs
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.

A portable application may use different file IO interfaces than the

Lv Zheng 83b80bace4 ACPICA: OSL: Clean up acpi_os_printf()/acpi_os_vprintf() stubs
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.

Lv Zheng e8c038a3c6 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.

Lv Zheng 0f929fbf0d ACPICA: Tables: Add new mechanism to skip NULL entries in RSDT and XSDT.
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

Original solution on Linux is to use an alternative heathy root table

      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.

Lv Zheng c79322677d ACPICA: acpidump: Add support to force using RSDT.
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.

Lv Zheng d63f37901e ACPICA: acpidump: Fix truncated RSDP signature validation.
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 could help to fix the issue that
"RSD " matches but "RSD PTR " doesn't match.  Lv Zheng.

Lv Zheng d87a2b75cd ACPICA: acpidump: Fix code issue in invoking fread in the loop.
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.

Thomas Renninger d7cddbb07b ACPI / tools: Introduce ec_access.c - tool to access the EC
This userspace tool accesses the EC through the ec_sys debug driver
(through /sys/kernel/debug/ec/ec0/io).

The EC command/data registers cannot be accessed directly, because they
may be manipulated by the AML interpreter in parallel.

The ec_sys driver synchronizes user space (debug) access with the AML
interpreter.

Lv Zheng edbe47c186 ACPICA: acpidump: Update Makefile to build acpidump from ACPICA.
This patch updates tools Makefile to use new acpidump.

ACPICA's acpidump relies on various ACPICA components/common/os_specific
source code.  They are located in various kernel folders, being searched
and compiled using vpath technique in Makefile.  These files include:
1. drivers/acpi/acpica/acapps.h
2. tools/power/acpi/common/getopt.c
3. tools/power/acpi/common/cmfsize.c
4. tools/power/acpi/os_specific/service_layers/oslinuxtbl.c
5. tools/power/acpi/os_specific/service_layers/osunixdir.c
6. tools/power/acpi/os_specific/service_layers/osunixmap.c

This patch has been tested on DELL Inspiron Mini, acpidump output can be
successfully generated by typing the following commands:
# cd tools/power/acpi
# make DEBUG=false
# sudo make install DESTDIR=/opt
# sudo make uninstall DESTDIR=/opt
# make clean
Or
# cd tools
# make acpi
# sudo make acpi_install
# sudo make acpi_uninstall
# make acpi_clean
A kernel build test is also performed on DELL Inspiron Mini to verify that
the changes done to actypes.h and aclinux.h won't affect the kernel
build process.

This patch cleans up old tools/power/acpi Makefile for further porting,
make it compiled in a similar way as the other tools.  No functional
changes.

The CFLAGS is modified as follows:
1. Previous cc flags:
   -Wall -Wstrict-prototypes -Wdeclaration-after-statement -Os -s \
   -D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include
2. Current cc flags:
   DEBUG=false:
   -D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include -Wall \
   -Wstrict-prototypes -Wdeclaration-after-statement -Os \
   -fomit-frame-pointer
   Normal:
   -D_LINUX -DDEFINE_ALTERNATE_TYPES -I../../../include -Wall \
   -Wstrict-prototypes -Wdeclaration-after-statement -O1 -g -DDEBUG
