efc5fe07a2 kernel: overhaul unused stack measurement
The existing stack_analyze APIs had some problems:

1. Not properly namespaced
2. Accepted the stack object as a parameter, yet the stack object
   does not contain the necessary information to get the associated
   buffer region, the thread object is needed for this
3. Caused a crash on certain platforms that do not allow inspection
   of unused stack space for the currently running thread
4. No user mode access
5. Separately passed in thread name

We deprecate these functions and add a new API
k_thread_stack_space_get() which addresses all of these issues.

A helper API log_stack_usage() also added which resembles
STACK_ANALYZE() in functionality.

Fixes: #17852

578dbe1c0a Bluetooth: Mesh: Support reliable sending when publishing
Until now the choice of reliable sending (segmented messages with

the payload would fit a single unsegmented message.

8ccc04de6a tracing: add infrastructure for collection of tracing data
First, this commit adds user interface in tracing_format.h which
can trace both string format and data format packet.

Second, it adds method both for asynchronous and synchronous way.
For asynchronous method, tracing packet will be buffered in tracing
buffer first, tracing thread will output the stream data with the
help of tracing backend when tracing thread get scheduled.

Third, it adds UART and USB tracing backend for asynchronous
tracing method, and adds POSIX tracing backend for synchronous
tracing way.

Also it can receive command from host to dynamically enable and
disable tracing to have host capture tracing data conveniently.

These have been replaced by the appropriate call to
gpio_pin_interrupt_configure().  While the disable function could be
implemented using the new functionality, the enable function cannot

gpio_pin_interrupt_configure() is invoked from within
gpio_pin_configure() to support legacy code that combines pin and
interrupt configuration.  Expressing a disabled interrupt by a zero
value for interrupt flags causes this invocation to disable interrupts

direction.

leaving the interrupt configuration unchanged.

af972c2c47 api: gpio: Align GPIO dt-bindings flags with Linux DTS
This commit makes following changes to GPIO dt-bindings flags:
- Added GPIO_ACTIVE_LOW, GPIO_ACTIVE_HIGH to indicate pin active state.
- Added GPIO_OPEN_DRAIN, GPIO_OPEN_SOURCE to configure single ended pin
  driving mode.
- Added GPIO_PULL_UP, GPIO_PULL_DOWN flags.
- GPIO_INPUT, GPIO_OUTPUT to configure pin as input or output.
- Added GPIO_OUTPUT_LOW, GPIO_OUTPUT_HIGH flags to initialize output
  in low or high state.
- reworked GPIO_INT_* flags to configure pin interrupts.
- following flags were deprecated: GPIO_DIR_*, GPIO_DS_DISCONNECT_*,
  GPIO_PUD_*, GPIO_INT_ACTIVE_*, GPIO_INT_DOUBLE_EDGE, GPIO_POL_*.

To be aligned with Linux DTS standard any GPIO flags that should not be
used in DTS files are moved from include/dt-bindings/gpio/gpio.h file to
include/drivers/gpio.h with an exception of several old flags which
removal would cause DTS compilation errors. Those remaining old flags
will be removed from include/dt-bindings/gpio/gpio.h at a later stage.

6f36300219 drivers: timer: Add per-core ARM architected timer
ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.

This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).

So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.

This commit fixes an issue observed with SimpleLink sockets with
multiple definitions of `gethostname` function. So far, the definition
within `socket.h` was not visible when offloading was enabled.

As this is no longer the case, and SimpleLink partially uses POSIX

In zephyr_linker_sources().
This is done since the point of the location is to place things at given
offsets. This can only be done consistenly if the linker code is placed
into the _first_ section.

All uses of TEXT_START are replaced with ROM_START.

ROM_START is only supported in some arches, as some arches have several
custom sections before text. These don't currently have ROM_START or
TEXT_START available, but that could be added with a bit of refactoring
in their linker script.

No SORT_KEYs are changed.

This also fixes an error introduced when TEXT_START was added, where
TEXT_SECTION_OFFSET was applied to riscv's common linker.ld instead of
to openisa_rv32m1's specific linker.ld.

e06ba702d5 kernel/sched: Address thread abort termination delay issue on SMP
It's possible for a thread to abort itself simultaneously with an
external abort from another thread.  In fact in our test suite this is
a common thing, as ztest will abort its own spawend threads at the end
of a test, as they tend to be exiting on their own.

When that happens, the thread marks itself DEAD and does all its
scheduler bookeeping, but it is STILL RUNNING on its own stack until
it makes its way to its final swap.  The external context would see
that "dead" metadata and return from k_thread_abort(), allowing the
next test to reuse and spawn the same thread struct while the old
context was still running.  Obviously that's bad.

Unfortunately, this is impossible to address completely without
modifying every SMP architecture to add a API-visible hook to every
swap that signals completion.  In practice the best we can do is add a
delay.  But note the optimization: almost always, the scheduler IPI
catches the running thread and kills it from interrupt context
(i.e. on a different stack).  When that happens, we know that the
interrupted thread will never be resumed (because it's dead) and can
elide the delay.  We only pay the cost when we actually detect a race.

0ff77b10e1 crypto: api: New capability flag CAP_NO_IV_PREFIX
Zephyr crypto API currently does not allow IV to be treated as separate
entity. This is mostly due to fact that underlying libraries expect the
IV to be prefixed to the cipher/plain text for performance reasons. But
there are cases where the IV is derived from other sources and not
directly transmitted to the other end. In such cases, it must be treated
as a first class citizen.

This patch adds a new capability flag `CAP_NO_IV_PREFIX` to the crypto
API that allows operations without prefixing the IV to the cipher/plain
text. When `CAP_NO_IV_PREFIX` is active (and supported), the IV passed
to cipher_*_op() must not be modified.

As a side effect, the length of the cipher/plain texts are equal;
allowing for in-place encryption/decryption.

publishing. This can't be recovered from, and as such, no valid model
implementation could return an error from this callback, and there was
no way to skip a periodic publish.

92f61b8075 include: dfu: Add extern "C" in mcuboot.h
I ran into a build failure trying to use Zephyr's MCUmgr.  It was a
missing symbol at link time, and since I am using C++, I looked to see
if it was a name mangling issue.  The mcuboot.h header file was missing
`extern "C"` guards, which was the root cause of the issue.

This commit adds C++ support to mcuboot.h by adding in `extern "C"`
guards.  I validated this change by building and running my DFU
application with MCUmgr successfully.

The application may want to know the configured mode without inspecting
Kconfig macros; this is important for proper management of BASELINE

bc8524eb82 arch: arm: Rewrite Cortex-R reset vector function.
This commit addresses the following issues:

1. Add a new Kconfig configuration for specifying Dual-redundant Core
   Lock-step (DCLS) processor topology.

2. Register initialisation is only required when Dual-redundant Core
   Lock-step (DCLS) is implemented in hardware. This initialisation is
   required on DCLS only because the architectural registers are in an
   indeterminate state after reset and therefore the initial register
   state of the two parallel executing cores are not guaranteed to be
   identical, which can lead to DCCM detecting it as a hardware fault.
   A conditional compilation check for this hardware configuration
   using the newly added CONFIG_CPU_HAS_DCLS flag has been added.

3. The existing CPU register initialisation code did not take into
   account the banked registers for every execution mode. The new
   implementation ensures that all architectural registers of every
   mode are initialised.

4. Add VFP register initialisation for when floating-point support is
   enabled and the core is configured in DCLS topology. This
   initialisation sequence is required for the same reason given in
   the first issue.

5. Add provision for platform-specific initialisation on Cortex-R
   using PLATFORM_SPECIFIC_INIT config and z_platform_init function.

6. Remove seemingly pointless and inadequately defined STACK_MARGIN.
   Not only does it violate the 8-byte stack alignment rule, it does
   not provide any form of real stack protection.

The SRAM address and size are currently available as both
DT_SRAM_{BASE_ADDRESS,SIZE} and as CONFIG_SRAM_{BASE_ADDRESS,SIZE} (via

Use the CONFIG_SRAM_* versions everywhere, and remove generation of the

The Kconfig symbols currently depend on 'ARC || ARM || NIOS2 || X86'.
Not sure why, so I removed it.

It looks like no configuration files set CONFIG_SRAM_* at the moment, so
another option might be to use the DT_* symbols everywhere instead. Some
Kconfig.defconfig.series files add defaults to them though.

d76ae46c0c lib: os: make snprintk fns generally available
The intention of disabling CONFIG_PRINTK is that all
invocations of it will compile to nothing, saving a lot
of runtime overhead and footprint since all the format
strings are completely dropped; instances of printk()
and related functions are no-ops.

However, some subsystems need snprintk() for string
processing, since the snprintf() implementations in even
minimal C library are too costly in text footprint or
stack usage for some applications. This processing is
required for the application to even function.

This patch continues to have disabling  CONFIG_PRINTK to
cause the non snprintk functions to become no-ops, but
now we always compile the necessary bits for snprintk(),
relying on gc-sections to discard them if unused.

z_vprintk() is now unconditionally defined in the header
since it is not tied to any particular output sink and
is intended for users who know exactly what they are
doing (it's in zephyr private scope).

9f2916b943 logging: fix LOG_HEXDUMP_* in C++.
Previously, there were two issues when attempting to use LOG_HEXDUMP_*
from C++:

First, gcc and clang in C mode both allow implicit pointer conversion
by default, but require -fpermissive, which no one should ever use, in
C++ mode. Furthermore, -Wpointer-sign, the warning emitted in C for
convertion between pointers to types of different signedness (e.g. char*
vs u8_t*) is explicitly disabled in Zephyr. Switch the various hexdump
functions to void*, which is guaranteed to work in both languages.

Second, the soon-to-be-standardized C++20 version of designated
initializers requires that the designators appear in the same order as
they are declared in the type being initialized.

2802fa4e6d treewide: avoid address-of-compound-literal idiom in headers
In C99 the construct (T){init-list} is called a compound literal, and
is an lvalue.  In C++ it is simply a cast expression to non-rvalue
type, which is a prvalue.  In both languages the expression is a
temporary, but in C99 taking its address is well-defined while in C++
it is an error diagnosed as "taking address of temporary".

Headers that may be used in C++ application code must avoid invalid
expressions.  Replace all uses of &(T){init-list} in headers with the
functionally equivalent but C++-legal (T[]){{init-list}}.

Low frequency and high frequency clocks had separate devices
while they are actually handled by single peripheral with single

argument in the API was used for other purposes and there was
no way to pass the information which clock should be controlled.
Implementation changes some time ago and subsys parameter was
no longer used. It now can be used to indicate which clock should
be controlled.

Change become necessary when nrf5340 is taken into account where
there are more clocks and current approach would lead to create

This commit targets solving issue #17731 over the LL_SW_SPLIT
arch of the BLE stack in Zephyr. This functionality is exposed
to the user as HCI Zephyr Command extensions

- BT_HCI_OP_VS_WRITE_TX_POWER_LEVEL
- BT_HCI_OP_VS_READ_TX_POWER_LEVEL

which enable Tx power read/write operations within BLE radio events
on a per role/connection basis.

The functionality is enabled upon the Kconfig advanced configuration
triggered by

- BT_CTLR_TX_PWR_DYNAMIC_CONTROL

depending on the enablement of Zephyr HCI vendor-specific command
extensions.

Necessary low-level radio HAL functionality and power definitions
are also supplied to address the high-level functionality of
controlling the Tx power.

2d859cc147 Bluetooth: Mesh: Make model publication struct more compact
commit 42d330406e introduced the FastPeriodDivisor value to
to the model publication struct. Based on the way it was grouped it
seems the intention was to fit it within the same octet as other bit
fields, but it actually makes the octet overflow by one bit. This ends
up creating another u8_t variable which in turn adds 24 bits of
padding after it.

To keep the size of the struct as compact as possible, group the flag
together with the key index, since that only requires 12 bits. Some
care is needed here, since the mesh stack does have special internal
key index values that require more than 12 bits such as
BT_MESH_KEY_UNUSED and BT_MESH_KEY_DEV. In this case restricting
ourselves to 12 bits is fine since the value in the model publication
struct follows 1:1 the value received in the Config Model Publication
Set message, and there the parameter is defined to be exactly 12 bits.

checks changed files.

Move the 'target-notes' target in boards/xtensa/odroid_go/doc/index.rst
to get rid of the trailing blank line there. It was probably misplaced.

7baf3f74a9 interrupt_controller: gic: Support PPIs
The GIC-400 driver currently only supports SPIs because the (32) offset
for the INTIDs is hard-coded in the driver. At the driver level there is
no really difference between PPIs and SPIs so we can easily extend the
driver to support PPIs as well.

This is useful if we want to add support for the ARM Generic Timers that
use INTIDs in the PPI range.

SPI interrupts are in the range [0-987]. PPI interrupts are in the range
[0-15].

This commit adds interrupt 'type' cell to the GIC device tree binding
and changes the 'irq' cell to use interrupt type-specific index, rather
than a linear IRQ number.

The 'type'+'irq (index)' combo is automatically fixed up into a linear
IRQ number by the scripts/dts/gen_defines.py script.

b30b480c7c Bluetooth: UUID: Expose bt_uuid_to_str to application
Expose the bt_uuid_to_str function as an API to the application.
This aligns this function with the bt_addr_to_str function call. This
allows the application to use this function without having to enable
the BT_DEBUG option.

Move the in-place bt_uuid_str to internal logging, this is mainly done
due to the limitation in the log_strdup that shouldn't be exposed to the
application.

a058219245 toolchain: fix __BYTE_ORDER__ not defined for XCC
Commit 571741a0c5 introduced a block to determine __BYTE_ORDER__
within toolchain/gcc.h. However, toolchain/xcc.h defined
__BYTE_ORDER__ there but the early inclusion of gcc.h causes
errors since __BYTE_ORDER__ cannot be determined within gcc.h.
So wrap around the gcc.h include with a fake __BYTE_ORDER__ to
bypass the check in gcc.h.

Also set the __BYTE_ORDER__ to the correct __ORDER_*_ENDIAN__
macro.
