Fixed usage build target.
Previously, `ninja usage` would print:
Build flags:
ninja VERBOSE=1 [targets] verbose build
This is clearly wrong, as VERBOSE=1 is for make targets.
To support both ninja based builds and make based build systems, the
CMAKE_MAKE_PROGRAM is now exported from the calling CMake / build
instance, and the verbose flag is set depending on whether ninja or
make is used as build program.

When ZephyrConfig package is being version checked, then

This is joint work with Kumar Gala (see signed-off-by).
This supports a new devicetree macro syntax coming. It's not really
worth mixing up the old and the new generation scripts into one file,
because:
- we aim to remove support for the old macros at some point, so it
will be cleaner to start fresh with a new script based on the old one
that only generates the new syntax
- it will avoid regressions to leave the existing code alone while
we're moving users to the new names
Keep the existing script by moving it to gen_legacy_defines.py and
changing a few comments and strings around. It's responsible for
generating:
- devicetree.conf: only needed by deprecated kconfigfunctions
- devicetree_legacy_unfixed.h: "old" devicetree_unfixed.h macros
Put a new gen_defines.py in its place. It generates:
- zephyr.dts
- devicetree_unfixed.h in the new syntax
Include devicetree_legacy_unfixed.h from devicetree.h so no DT users
are affected by this change.

There are two problems with the way runners.yaml is being created:
1. The dictionary which contains the arguments for each runner is
using the runner's name converted to a C identifier instead of the
runner's name itself. That causes west flash to fail when the two
are different, e.g. for 'misc-flasher' (runner name), which is
different than 'misc_flasher' (runner name as C identifier)
2. We need to make sure that the dictionary key maps to an empty list
if there are no arguments, which normally doesn't happen since the
runner usually at least takes the path of the file to flash or debug.
It does happen in the case of misc-flasher, though, since the whole
point of that runner is that it's an escape hatch for people with
out of tree scripts that nevertheless want 'west flash' integration
for things like sanitycheck device testing.
3. A copy/paste error is setting the debug runner to the flash runner.
Fix them all.

There are some issues with the behavior when rerunning CMake in an
already initialized build directory:
1. The check for assignments to promptless symbols in configuration
fragments isn't run when reconfiguring, because it only runs if
zephyr/.config doesn't exist
2. As outlined in
https://github.com/zephyrproject-rtos/zephyr/issues/9573, you can
get into situations where zephyr/.config is invalid (e.g. due to
being outdated), but menuconfig/guiconfig can't be run to fix it
3. If kconfig.py fails while merging fragments during reconfiguration,
it will ignore the fragments during the next reconfiguration and use
the existing zephyr/.config instead, because the fragment checksum
is calculated and saved before running kconfig.py
(Footnote: The input configuration file(s) to kconfig.py can be either a
list of configuration fragments, when merging fragments, or just
zephyr/.config, if the merged configuration is up-to-date. The output
configuration file is always zephyr/.config.)
To fix the first two issues, explicitly tell kconfig.py when it's
dealing with handwritten configuration input (fragments), via a new
--handwritten-input-configs flag. This is more robust than checking
whether zephyr/.config exists, which was the old logic.
When dealing with handwritten input, there should be no assignments to
promptless symbols. Assignments to promptless symbols is expected in
zephyr/.config however, because it doubles as configuration output.
When running menuconfig/guiconfig, the input configuration is
zephyr/.config rather than configuration fragments, so this change also
makes sure that menuconfig can always be run as long as zephyr/.config
exists and is up-to-date.
To fix the last issue, only write the checksum for the configuration
fragments if kconfig.py succeeds (which means it wrote a
zephyr/.config).
Also improve naming a bit, add help texts for the command-line
parameters to kconfig.py, and simplify write_kconfig_filenames() by
moving logic into it.
Partial fix for
https://github.com/zephyrproject-rtos/zephyr/issues/9573, without the

This commit splits the 'locore' and 'main' memory regions into
separate executable images and specifies the 'locore' as the boot
kernel, in order to prevent the QEMU direct multiboot kernel loader
from overwriting the BIOS and option ROM areas located in between
the two memory regions.
The Zephyr x86-64 kernel image consists of two discontiguous load
memory regions: 'locore' at 0x8000 and 'main' at 0x100000, but the
QEMU treats these as single contiguous memory region starting at
0x8000 and ending at (0x100000 + MAIN_IMAGE_SIZE - 1).
This results in the direct multiboot kernel loader overwriting the
BIOS and option ROM areas as part of the kernel loading process, and
causes any writable system regions to be corrupted (e.g. KVMVAPIC ROM).
By splitting the two discontiguous memory regions into separate images
and specifying only the boot image (i.e. 'locore') as the '-kernel',
it is possible to work around the QEMU direct kernel loading design
limitation.
This workaround is required to support the QEMU v4.2.0 and above.

Zephyr currently requires Python 3.4 or later. The core Python team
declared version 3.4 hit End of Life (EOL) in March, so there's no
reason to continue to support it if that's causing a burden, which it
is.
This commit allows Zephyr's Python scripts to depend on features
present in version 3.6 or later.
This does skip support for a currently active version of Python:
- Python 3.5 is actively supported by the core Python devs until 09/2020
- Zephyr's 2.2 release, the first which could include this change, is
tentatively scheduled for 02/2020.
However, almost all supported platforms are either unaffected, or
their users can upgrade easily:
- Windows users who need to can upgrade Python with:
choco upgrade python
- macOS users who need to can upgrade Python with:
brew upgrade python3
- Red Hat Enterprise Linux users who need to upgrade can use
Software Collections (SCLs), e.g. as described here:
https://developers.redhat.com/blog/2018/08/13/install-python3-rhel/
- CentOS Linux users also have access to SCLs, as described here:
https://wiki.centos.org/AdditionalResources/Repositories/SCL
- Ubuntu's current long-term support (LTS) release (Bionic Beaver,
version 18.04) ships with Python 3.6. It and all later versions of
Ubuntu won't be affected by this change.
- Debian's current stable release (Buster, version 10) ships Python 3.7
and likewise won't be affected.
The impact of this change is therefore biggest for older versions of
Linux. In particular, these are impacted:
- Older Ubuntu LTS releases.
- Ubuntu 16.04 ships Python 3.5; it is still supported by Canonical.
- Ubuntu 14.04 ships Python 3.4, which is EOL. This Ubuntu version
is also no longer getting standard support from Canonical. Paying
customers are receiving security updates only.
https://wiki.ubuntu.com/Releases
- Older Debian versions.
- Debian 9 (stretch) ships Python 3.5 and is still a supported
Debian version.
- Debian 8 (jessie) ships Python 3.4, which is EOL. This Debian
version is no longer receiving mainline maintenance by the Debian
project. LTS updates are provided by interested community
volunteers only.
https://wiki.debian.org/LTS
Affected Linux users will no longer have a system Python 3 which works
"out of the box" with Zephyr after this change. Some ideas for these
users are:
- Use Zephyr v2.1 or v1.14 LTS, which are maintained and still
support Python 3.4
- Compile Python 3.6 or later from source and use it within a venv:
https://docs.python.org/3/library/venv.html
- Use something like https://github.com/pyenv/pyenv
Python 3.6 has compelling new features which make writing Zephyr's
scripts easier, and which it would be good to be able to rely upon.
This motivates moving from Python 3.4 to 3.6 instead of 3.5.
My personal killer 3.6 features motivating skipping 3.5 (YMMV):
- Windows console and file system encodings are UTF-8 (PEPs 528 and
529): Zephyr's scripts, and many utilities related to git, broadly
assume strings are UTF-8, so this is very helpful
- os.PathLike and the file system path protocol (PEP 519) allow
intermixing "smart" paths in pathlib with existing os.path based
code
- f-strings (PEP 0498) are a wonderful and efficient string
interpolation mechanism
- CPython dictionaries are insertion ordered as an implementation
detail starting with 3.6, which in practice helps with
reproducibility (and *all* Python implementations have insertion
ordered dicts starting with 3.7)

some toolchains would use the source file for the file name stem.
So, the resulting dependency file is empty_file.d instead of one
with the board name. Fix this by passing -MF to explicitly tell
the compiler the name of the dependency file.

Renode 1.8 introduced a behaviour change in which it automatically
launches the telnet monitor on the TCP port 1234 by default.
In order to prevent sanitycheck failures from multiple renode instances
attempting to listen on the TCP port 1234 simultaneously, this commit
disables renode telnet monitor by specifying '--port -2' (a negative
number lower than -1 is required to disable telnet monitor because of
the way renode command line parser is implemented).

The toolchain_ld_cpp macro currently uses zephyr_ld_options function
to link libstdc++, instead of zephyr_link_libraries which is actually
intended for this purpose.
This commit replaces the usage of zephyr_ld_options with
zephyr_link_libraries as the former may erroneously filter out
-lstdc++ and the latter ensures that this linker flag is
unconditionally forwarded to the linker.

This commit refactors kernel and arch headers to establish a boundary
between private and public interface headers.
The refactoring strategy used in this commit is detailed in the issue
This commit introduces the following major changes:
1. Establish a clear boundary between private and public headers by
removing "kernel/include" and "arch/*/include" from the global
include paths. Ideally, only kernel/ and arch/*/ source files should
reference the headers in these directories. If these headers must be
used by a component, these include paths shall be manually added to
the CMakeLists.txt file of the component. This is intended to
discourage applications from including private kernel and arch
headers either knowingly and unknowingly.
- kernel/include/ (PRIVATE)
This directory contains the private headers that provide private
kernel definitions which should not be visible outside the kernel
and arch source code. All public kernel definitions must be added
to an appropriate header located under include/.
- arch/*/include/ (PRIVATE)
This directory contains the private headers that provide private
architecture-specific definitions which should not be visible
outside the arch and kernel source code. All public architecture-
specific definitions must be added to an appropriate header located
under include/arch/*/.
- include/ AND include/sys/ (PUBLIC)
This directory contains the public headers that provide public
kernel definitions which can be referenced by both kernel and
application code.
- include/arch/*/ (PUBLIC)
This directory contains the public headers that provide public
architecture-specific definitions which can be referenced by both
kernel and application code.
2. Split arch_interface.h into "kernel-to-arch interface" and "public
arch interface" divisions.
- kernel/include/kernel_arch_interface.h
* provides private "kernel-to-arch interface" definition.
* includes arch/*/include/kernel_arch_func.h to ensure that the
interface function implementations are always available.
* includes sys/arch_interface.h so that public arch interface
definitions are automatically included when including this file.
- arch/*/include/kernel_arch_func.h
* provides architecture-specific "kernel-to-arch interface"
implementation.
* only the functions that will be used in kernel and arch source
files are defined here.
- include/sys/arch_interface.h
* provides "public arch interface" definition.
* includes include/arch/arch_inlines.h to ensure that the
architecture-specific public inline interface function
implementations are always available.
- include/arch/arch_inlines.h
* includes architecture-specific arch_inlines.h in
include/arch/*/arch_inline.h.
- include/arch/*/arch_inline.h
* provides architecture-specific "public arch interface" inline
function implementation.
* supersedes include/sys/arch_inline.h.
3. Refactor kernel and the existing architecture implementations.
- Remove circular dependency of kernel and arch headers. The
following general rules should be observed:
* Never include any private headers from public headers
* Never include kernel_internal.h in kernel_arch_data.h
* Always include kernel_arch_data.h from kernel_arch_func.h
* Never include kernel.h from kernel_struct.h either directly or
indirectly. Only add the kernel structures that must be referenced
from public arch headers in this file.
- Relocate syscall_handler.h to include/ so it can be used in the
public code. This is necessary because many user-mode public codes
reference the functions defined in this header.
- Relocate kernel_arch_thread.h to include/arch/*/thread.h. This is
necessary to provide architecture-specific thread definition for
'struct k_thread' in kernel.h.
- Remove any private header dependencies from public headers using
the following methods:
* If dependency is not required, simply omit
* If dependency is required,
- Relocate a portion of the required dependencies from the
private header to an appropriate public header OR
- Relocate the required private header to make it public.

Of the 1.7s or so that CMake spends in Configure-time there is 0.1s
spent to determine whether west can flash or not. This is significant
compared to the usefulness of flash-check.
AFAICT when installing west there is no longer a two-step procedure
where first a bootstrapper that can't flash is installed, and then a
proper west is installed, so the risk of having installed the
bootstrapper is no longer something we should spend 100ms testing for.
This patch removes the check, thereby speeding up CMake by 100ms.

Since x86_64-zephyr-elf is a multi-lib toolchain, m32/m64
need to be specified for the compiler to return the correct
library path when queried (e.g. --print-libgcc-file-name).
This affects the compile check done by CMake. Without these
flags, the compiler returns incorrect toolchain path (e.g.
requiring 64-bit libraries but returning 32-bit library path).
This also affects compiler flag checks for "-lstdc++". Incorrect
library path results in error when checking for "-lstdc++", and
this flag will not be used for the build. This results in
undefined references when compiling C++ code.
This creates target_x86.cmake to add the necessary flags for
CMake to use. The target_x86_64.cmake is also created to
mirror the same change.
Also removing the -m32 flags for host-gcc since we are not

The old code is kept to generate some deprecated defines, using the

The new parser is implemented in three files in scripts/dts/:

files and bindings and creates Device instances with all the data for
a device.
gen_defines.py:
A script that uses edtlib.py to generate generated_dts_board.conf and
generated_dts_board_unfixed.h. Corresponds to extract_dts_includes.py
and the files in extract/ in the old code.
testdtlib.py:

We need to pass -m64 instead of -m32 when CONFIG_64BIT is set.
This is pretty x86 centric. Many platforms don't have the ability
to select between 32-bits or 64-bits builds and either of those should
be dropped in that case with restriction on the available configuration
done elsewhere. But for the time being this allows for testing both.

This reverts commit b4078c557d / zephyrproject-rtos/zephyr#17495
This revert is needed for two reasons:
1. As reported by Lawrence King at
https://lists.zephyrproject.org/g/users/message/1566
this breaks incremental builds with ninja:
cd sample/hello_world
west build -b qemu_x86
touch src/main.c
west build -b qemu_x86
hello_world/build/../src/main.c:11: multiple definition of main';
app/libapp.a(main.c.obj):samples/hello_world/build/../src/main.c:11:
first defined here
collect2: error: ld returned 1 exit status
ar tf build/app/libapp.a
main.c.obj
main.c.obj
This does NOT break incremental builds with GNU Make, not sure why not.
2. Less urgently, I finally got someone from the CMake team to help me
and point me at an alternative solution that doesn't rely on CMake
internals: https://gitlab.kitware.com/cmake/cmake/issues/19474
I was about to try it when Lawrence reported the regression above.

Quoting GNU ar man/info page:
'D'
Operate in _deterministic_ mode. When adding files and the archive
index use zero for UIDs, GIDs, timestamps, and use consistent file
modes for all files. When this option is used, if 'ar' is used
with identical options and identical input files, multiple runs
will create identical output files regardless of the input files'
owners, groups, file modes, or modification times.
If 'binutils' was configured with
'--enable-deterministic-archives', then this mode is on by default.
It can be disabled with the 'U' modifier, below.

Not all DTS changes are board specific and we should support overlays
that can be used with multiple boards. For example with a sensor, for
example:
Use this overlay for a sensor:
&arduino_i2c {
bme280@76 {
compatible = "bosch,bme280";
reg = <0x76>;
label = "BME280";
};
};
This will work with any board that has &arduino_i2c defined, but should
also work if you specify the instance directly (&i2c0 or &i2c1).

The Particle mesh feather boards provide device-tree overlays that
allow individual applications to select the SPI peripheral to be

sanitycheck takes any "extra_config" list found in the testcase.yaml
file and generates an "overlay" file from it. This file is placed in
the per-test build directory and passed to cmake/kconfig.cmake through a
-DOVERLAY_CONF= option set in the (also) generated sanity-out/Makefile.
This commit moves this generated config overlay to a subdirectory one
level down from the build directory, otherwise kconfig.cmake picks it
up *twice*: once from the -DOVERLAY_CONF= option already mentioned above
and a second time because kconfig.cmake scans the build directory and
blindly picks up ALL files ending with .conf[*]. The second pickup is
problematic because kconfig.cmake currently gives it the top precedence,
even higher than anything the user espressed with --extra-args=CONFIG_*
Here's a quick and simple demonstration of the issue fixed by this
commit:
cd $ZEPHYR_BASE/samples/net/sockets/net_mgmt/
sanitycheck -T. -p qemu_x86 -b -v # --extra-args=CONFIG_USERSPACE=y|n
grep CONFIG_USERSPACE $(find sanity-out/ -name .config)
.net_mgmt.kernelmode/zephyr/.config: # CONFIG_USERSPACE is not set
.net_mgmt.usermode/zephyr/.config: CONFIG_USERSPACE=y
grep 'Merged configuration' $(find sanity-out/ -name build.log)
Without this commit, attemps to override anything with
--extra-args=CONFIG_ are silently dropped on the floor.
For more background this issue was found while using the recipe in
commit message 4afcc0f8af
[*] picking up all .conf files is debatable but a much bigger debate
with backward compatibility implications. This small fix makes
absolutely zero difference to anyone or anything not using sanitycheck.

This allows for inclusion of out-of-tree toolchain cmake files
relating to compiler and linker for both target and generic
toolchains.
The base path used was ZEPHYR_BASE, instead of TOOLCHAIN_ROOT, thus
making it impossible to load the out-of-tree toolchain specific
cmake files.
In addition, the generic toolchain may now specify a generic cmake
file for the linker, similar to the target toolchain linker.

thus allowing for easier porting to other, perhaps commercial,

Because CMake explicitly deduplicates arguments, it is not possible
to use toolchain_cc_imacros() multiple times as the later "-imacros"
are stripped away, leaving the associated file arguments dangling.
The documented workaround in the CMake manual involves some "SHELL:..."
construct but that doesn't get through zephyr_compile_options()
undammaged.
Let's simply remove this issue altogether by replacing "-imacros x.h"
with the joined form "--imacros=x.h" instead. Both gcc and clang
support this syntax.
FYI, this joined form is also available for other arguments such as:
-include x.h --> --include=x.h
-A foo --> --assert=foo
-D foo --> --define-macro=foo
-U foo --> --undefine-macro=foo

This is a graphical configuration interface written in Tkinter. Like
menuconfig.py, it supports showing all symbols (with invisible symbols
in red) and jumping directly to symbols. Symbol values can also be
changed directly from the jump-to dialog.
This interface should feel a lot smoother than menuconfig.py on Windows.
When single-menu mode is enabled, a single menu is shown at a time, like
in the terminal menuconfig. Only this mode distinguishes between symbols
defined with 'config' and symbols defined with 'menuconfig'.
Compatible with both Python 2 and Python 3. Has been tested on X11,
Windows, and macOS.
