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.

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.

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.

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.

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: 671cc68dc6
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.

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 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.

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.
