Jiri Slaby 7553961631 tools: power/acpi, revert to LD = gcc
Commit 7ed1c1901f (tools: fix cross-compile var clobbering) removed
setting of LD to $(CROSS_COMPILE)gcc. This broke build of acpica
(acpidump) in power/acpi:
 ld: unrecognized option '-D_LINUX'

The tools pass CFLAGS to the linker (incl. -D_LINUX), so revert this
particular change and let LD be $(CC) again. Note that the old behaviour
was a bit different, it used $(CROSS_COMPILE)gcc which was eliminated by
the commit 7ed1c1901f. We use $(CC) for that reason.

Martin Kelly 7ed1c1901f tools: fix cross-compile var clobbering
Currently a number of Makefiles break when used with toolchains that
pass extra flags in CC and other cross-compile related variables (such
as --sysroot).

Thus we get this error when we use a toolchain that puts --sysroot in
the CC var:

  ~/src/linux/tools$ make iio
  [snip]
  iio_event_monitor.c:18:10: fatal error: unistd.h: No such file or directory
    #include <unistd.h>
             ^~~~~~~~~~

This occurs because we clobber several env vars related to
cross-compiling with lines like this:

  CC = $(CROSS_COMPILE)gcc

Although this will point to a valid cross-compiler, we lose any extra
flags that might exist in the CC variable, which can break toolchains
that rely on them (for example, those that use --sysroot).

This easily shows up using a Yocto SDK:

  $ . [snip]/sdk/environment-setup-cortexa8hf-neon-poky-linux-gnueabi

  $ echo $CC
  arm-poky-linux-gnueabi-gcc -march=armv7-a -mfpu=neon -mfloat-abi=hard
  -mcpu=cortex-a8
  --sysroot=[snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi

  $ echo $CROSS_COMPILE
  arm-poky-linux-gnueabi-

  $ echo ${CROSS_COMPILE}gcc
  krm-poky-linux-gnueabi-gcc

Although arm-poky-linux-gnueabi-gcc is a cross-compiler, we've lost the
--sysroot and other flags that enable us to find the right libraries to
link against, so we can't find unistd.h and other libraries and headers.
Normally with the --sysroot flag we would find unistd.h in the sdk
directory in the sysroot:

  $ find [snip]/sdk/sysroots -path '*/usr/include/unistd.h'
  [snip]/sdk/sysroots/cortexa8hf-neon-poky-linux-gnueabi/usr/include/unistd.h

The perf Makefile adds CC = $(CROSS_COMPILE)gcc if and only if CC is not
already set, and it compiles correctly with the above toolchain.

So, generalize the logic that perf uses in the common Makefile and
remove the manual CC = $(CROSS_COMPILE)gcc lines from each Makefile.

Note that this patch does not fix cross-compile for all the tools (some
have other bugs), but it does fix it for all except usb and acpi, which
still have other unrelated issues.

I tested both with and without the patch on native and cross-build and
there appear to be no regressions.

Lv Zheng 03c5b6b0da ACPICA: acpidump: Add DSDT/FACS instance support for Linux and EFI
ACPICA commit 343fc31840d40c06001f3b170ee5bcdfd3c7f3e0

ACPI spec allows to configure different 32-bit/64-bit table addresses for
DSDT and FACS. And for FACS, it's meaningful to dump both of them as they
are used to support different suspend protocols.

While:
1. on Linux, only 1 instance is supported for DSDT/FACS; and
2. on EFI, the code in osl_get_table() is buggy with special table instances,
   causing endless file dump for such tables (reported by Shao Ming in link
   #2).

This patch adds DSDT/FACS instance support for Linux/EFI acpidump. Fixed by
Lv Zheng.

Lv Zheng 65082bfcb4 ACPICA: CLib: Add short multiply/shift support
ACPICA commit 01b8f5a2350b9cc329cd8402ac8faec36fc501f5

In order to build ACPICA EFI tools with EDK-II on Windows, 64-bit
multiply/shift supports are also required to be implemented. Otherwise,
MSVC complains:
 acpidump.lib(utstrtoul64.obj) : error LNK2001: unresolved external symbol __allmul
 acpidump.lib(uthex.obj) : error LNK2001: unresolved external symbol __aullshr

Note:
1. This patch also splits _EDK2_EFI from _GNU_EFI as they might have
   different math64 supports.
2. Support of gcc math64 is not included in this patch.
3. Support of EDK2 arch independent math64 is done via linking to base_lib.

This patch fixes this issue. Reported by Shao Ming, fixed by Lv Zheng.

For Linux kernel, this patch is a functional no-op.

-iwithprefix include is required to include <stdarg.h> which contains
compiler specific implementation of vargs when -nostdinc is specified.
-fno-builtin is required for GCC to avoid optimization performed printf().
This optimization cannot be automatically disabled by specifying -nostdlib.

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.

Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.

Lv Zheng 4e2fc6a0aa ACPICA: Clib/EFI: Fix wrong order of standard integer types/IO handles
ACPICA commit 7f9b359b7c78c69b07f62eb2d58f710c351fd75d

EFI header should use standard C library stuffs (integer types and IO
handles) rather than implementing such standard stuffs.
This patch fixes this issue by:
1. Implementing standard integer types for ACPI_USE_STANDARD_HADERS=n;
2. Defining EFI types using standard integer types and standard IO handles;
3. Tuning header inclusion order and environment definition order;
4. Removing wrong standard header inclusion from ACPICA core files;
5. Moving several application headers from acpidump.h to acenv.h.
This patch corrects some of them. Lv Zheng.

Except some harmless header inclusion re-ordering, Linux kernel is not
affected by this change.

ACPICA commit 7cf411136c69ef0b8f184b96599eb45c15b89226

When standard size_t is not defined due to ACPI_USE_STANDARD_HEADERS=n,
we shouldn't use size_t, but should use acpi_size instead. This fixes such
build issue. Lv Zheng.

ACPICA commit 408198c8c9786f9f104ee925020c3ab1701906e4

The acpi_gbl_debug_timeout which is used by acpiexec -et option now is only
implemented in oswinxf.c and used for WIN32 builds. This makes it very
difficult to remember that we need to add this variable to other os
specific layer files in order for linking. This patch makes it a global
option dependent on ACPI_APPLICATION so that it can always be linked by the
applications. Lv Zheng.

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f

This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.

Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

Lv Zheng 37645d6590 tools/power/acpi: Add userspace AML interface support
This patch adds a userspace tool to access Linux kernel AML debugger
interface.

Tow modes are supported by this tool:
1. Interactive: Users are able to launch a debugging shell to talk with
   in-kernel AML debugger.
   Note that it's user duty to ensure kernel runtime integrity by using
   this debugging tool:
   A. Some control methods evaluated by the users may result in kernel
      panics if those control methods shouldn't be evaluated by the OSPMs
      according to the current BIOS/OS configurations.
   B. Currently if a single stepping evaluation couldn't run to an end,
      then the synchronization primitives acquired by the evaluation may
      block normal OSPM control method evaluations.
2. Batch: Users are able to execute debugger commands in a script.
   Note that in addition to the above duties, it's user duty to ensure
   script runtime integrity by using this debugging tool in this mode:
   C. Currently only those commands that are not used for single stepping
      are suitable to be used in this mode.
   D. If the execution of the command may cause a failure that could result
      in an endless kernel execution, the execution of the script may also
      get blocked.
To exit the utility, currently "exit/quit" commands are recommended, but
ctrl-C" can also be used.
