Jan Beulich f907784c32 libacpi: drop mk_dsdt's -d / --debug option
Recent Clang complains about the "debug" static variable only ever being
written to. Drop it and the command line option controlling it.

Ross Lagerwall ea12f9d257 libacpi: Pass missing --dm_version to mk_dsdt
Commit 19ab8356ab ("tools: remove support for running a guest with
qemu-traditional") made passing --dm_version to mk_dsdt mandatory on
x86 but didn't fix all the invocations of it.

The previous default was qemu-xen-traditional so with that removed set
the dm_version to qemu-xen for this invocation.

Without this change, Xen fails to build on x86 when using
--enable-rombios.

Andrew Cooper be1fdacf54 LICENSES: Remove the use of deprecated SPDX tags
The GPL and LGPL SPDX forms without an explicit -only or -or-later suffix are
deprecated and should not be used.  Update the documention.

Somewhat unhelpfully at the time of writing, this only appears to be indicated
by the separation of the two tables at https://spdx.org/licenses/

The recent changes to libacpi are the only examples of deprecated LGPL tags in
tree, so fix them all up.

For GPL, we have many examples using deprecated tags.  For now, just identify
them as such and recommend that no new instances get added.

Jan Beulich e93e635e14 libacpi: switch to SPDX
Commit 68823df358 ("acpi: Re-license ACPI builder files from GPLv2 to
LGPLv2.1") added references to a "special exception on linking described
in file LICENSE", without actually adding such a file. Quite likely
COPYING was meant instead, yet then its text matches LICENSES/LGPL-2.1
except for some explanatory text (clarifying the "only" aspect) at the
top (and formatting). Hence replace the text in all the files with SPDX
references to LGPL-2.1.

Note that dsdt_acpi_info.asl had no license text. An SPDX tag is being
added there nevertheless.

iasl hasn't been download by our build system for a while and the

Jan Beulich e006b2e3be libxl: fix libacpi dependency
$(DSDT_FILES-y) depends on the recursive make to have run in libacpi/
such that the file(s) itself/themselves were generated before
compilation gets attempted. The same, however, is also necessary for
generated headers, before source files including them would get
attempted to be compiled.

The dependency specified in libacpi's Makefile, otoh, is entirely
pointless nowadays - no compilation happens there anymore (except for
tools involved in building the generated files). Together with it, the
rule generating acpi.a also can go away.

Roger Pau Monné 858dbaaeda libacpi: fixes for iasl >= 20180427
New versions of iasl have introduced improved C file generation, as
reported in the changelog:

iASL: Enhanced the -tc option (which creates an AML hex file in C,
suitable for import into a firmware project):
  1) Create a unique name for the table, to simplify use of multiple
SSDTs.
  2) Add a protection #ifdef in the file, similar to a .h header file.

The net effect of that on generated files is:

-unsigned char AmlCode[] =
+#ifndef __SSDT_S4_HEX__
+#define __SSDT_S4_HEX__
+
+unsigned char ssdt_s4_aml_code[] =

The above example is from ssdt_s4.asl.

Fix the build with newer versions of iasl by stripping the '_aml_code'
suffix from the variable name on generated files.

This patch is the result of this perl rune:

Microsoft have defined an ACPI device to support switching Windows 10
between laptop/desktop mode and slate/tablet mode [1].

This patch adds an SSDT containing such a device. The presence of the
device is controlled by a new 'acpi_laptop_slate' boolean in xl.cfg.
The new device will not be present by default.

Julien Grall d066b5b9ba libacpi: fix compilation when cross building the tools
The tools (such as mk_dsdt) can be cross-built when it may not be
desirable to build them on the target.

The commit c4ac1077 "libxl/arm: Generate static ACPI DSDT table"
introduced support of ARM64 in mk_dsdt but also break cross-building
tools because the ACPI tables are not correct.

While mk_dsdt should generate ACPI table for the target architecture, it
currently generates the one for the host. This is because the source
code contains reference to the host architecture (__aarch64__,
__x86_64__, __i386__) when it should be the target architecture.

Replace all __aarch64__, __x86_64__, __i386__ by the corresponding
CONFIG_*.

Also expose the CONFIG_* to the source code as the currently only
exposed to the Makefile.

Roger Pau Monne 26c4f0b8a4 tools/libacpi: fix sed usage
Current usage of sed in the libacpi Makefile make uses of non-POSIX options,
that are not available on all the OSes supported by the Xen tools.

The '-i' option has slightly different semantics between GNU and BSD sed
implementations, while on the GNU version the suffix is optional, on the BSD
one it is not. Also BSD sed seems to have problems parsing the script
itself, reporting "extra characters at the end of d command".

Fix those issues by using a temporary intermediate file, and replace the
script with a simpler version that achieves the same purpose (removing the
initial license header comment).

Wei Liu 344da4f3ad libacpi: fix arm64 build
The arm64 build for libacpi was broken due to two reasons:

1. ACPI_BUILD_DIR was appended twice to dsdt_anycpu_arm.c.
2. The inclusion of firmware/Rules.mk overrided XEN_TARGET_ARCH, which
   made CONFIG_ARM disappear.

Fix those by:

1. Correctly generate full path for dsdt_anaycpu_arm.c.
2. Include tools/Rules.mk instead, because libacpi/Makefile doesn't rely
   on settings in firmware/Rules.mk.

While at it, use CONFIG_ARM_64 instead of CONFIG_ARM as it is more
accurate.

Shannon Zhao c4ac107799 libxl/arm: Generate static ACPI DSDT table
It uses static DSDT table like the way x86 uses. Currently the DSDT
table only contains processor device objects and it generates the
maximal objects which so far is 128.

While the GUEST_MAX_VCPUS is defined under __XEN__ or __XEN_TOOLS__, it
needs to add -D__XEN_TOOLS__ to compile mk_dsdt.c.

Also only check iasl for aarch64 in configure since ACPI on ARM32 is not
supported.
