923caadf3b kernel: delayed_work: update k_delayed_work_cancel documentation
Although the documentation states that only work items that have not
completed the delay can be cancelled, in fact pending items can also
be removed from a work queue.  Document that behavior

Also document the specific return value that will be obtained based on
the state of the work item at the time cancellation was attempted
using the current implementation.

16fe3af327 kernel: delayed_work: note restriction in re-using delayed work items
The delayed work work_q pointer is set on submission, and remains set
even after the work item completes.  Attempts to re-submit the
completed work item to a different queue will be rejected because the
code cannot distinguish a completed item from one that is still
waiting for a delay or to be processed.

Document this restriction.

a8e45c4f1e shell: dictionary commands feature
Adding dictionary commands concept. It simplifies creation of multiple
commands that are handled by a one function handler.

This is a special kind of static commands. Dictionary commands can be
used every time you want to use a pair: (string <-> corresponding data)
in a command handler. The string is usually a verbal description
of a given data. The idea is to use the string as a command syntax that
can be prompted by the shell and corresponding data can be used to
process the command.

79fa92229a mgmt: smp: shell: use net_buf API for storing UART SMP fragments
So far there was a simple char array used as buffer, with additional
variable representing number of bytes already written into it. After
full frame was written, a boolean flag was simply set to notify thread
about being ready to be processed. There was however no mechanism
implemented to prevent new incoming bytes from overwriting such buffer
before (or during) being processed.

Use net_buf to store temporary frame. Define dedicated net_buf_pool,
from which such buffer will be allocated and freed after being
processed. This will prevent from reusing the same buffer before having
it fully processed (and returning once again to available buffer pool)
in shell thread.

Define also fifo that will store buffers that are ready to be
processed. This will be the mechanism for notifying thread about new
UART SMP fragments.

net_buf pool and k_fifo are used on purpose, keeping in mind their
additional overhead (mostly in RAM/ROM usage). This makes the code ready
for increasing number of buffers if needed. In this commit however we
stick with only 1 buffer, to keep minimal changes in processing flow.

f7a5638871 net: lwm2m: Make bootstrap optional
Currently, after `CONFIG_LWM2M_RD_CLIENT_SUPPORT_BOOTSTRAP` is enabled,
the LwM2M engine will initiate bootstrap procedure on each run. This
approach limits the flexibility of the application, as it's not always
necessary to go over the bootstrap procedure (for instance, the
application may decide to store the security object obtained during the
bootstrap in flash, and restore it on boot).

Fix this by introducing an additional `flags` parameter to the
`lwm2m_rd_client_start()` function, which provides information whether
to run bootstrap in the current session or not.

84cdc6fd92 logging: Refactoring macro to avoid Coverity issue
Change a runtime log check such that Coverity does not report a
needless issue on every use of any log macro.

Before the change, this was used in log macros:

    else if(is_user_context || (_level <= LOG_RUNTIME_FILTER(_filter)))

If runtime filtering is not enabled, this expands to:

    else if(is_user_context || 1)

Because the level is compared to log level debug (4) and will always be,
equal or lower.
Coverity always reports this as a potential issue, since the
variable part (is_user_context) makes no difference.

After the change, a macro is used which expands into the original code
when runtime filtering is used, else it simply expands to:

    else if(true)

Which has equal semantics as the previous code but isn't flagged by
Coverity.

path for migrating host sub-devices via LPC to a lower pin count, higher
bandwidth bus. In addition to Host communication via the peripheral
channel, it provides virtual wires support, out-of-band communication,
and device mastering option over the Chipset SPI flash.

Becisdes introducing eSPI device in npcx7, this CL also includes:

1. Add eSPI device tree declarations.
2. Add npcx7-espi-vws-map.dtsi to present the relationship between eSPI
   Virtual-Wire signals, eSPI registers, and wake-up input sources.
3. Zephyr eSPI api implementation.
4, Add OOB (Out of Band tunneled SMBus) support.

However, horrible and difficult to comprehend things can happen if a

k_thread_create() is called on it.

Historically this has been a problem with test cases trying to be
parsimonious with thread objects and not properly cleaning up
after themselves. Add an assertion for this which should catch
both the illegal creation of a thread already active, or threads
racing to create the same thread object.

Fixes races where threads on another CPU are joining the
exiting thread, since it could still be running when
the joiners wake up on a different CPU.

Fixes problems where the thread object is still being
used by the kernel when the fn_abort() function is called,
preventing the thread object from being recycled or
freed back to a slab pool.

Fixes a race where a thread is aborted from one CPU while
it self-aborts on another CPU, that was currently worked
around with a busy-wait.

Precedent for doing this comes from FreeRTOS, which also
performs final thread cleanup in the idle thread.

Some logic in z_thread_single_abort() rearranged such that
when we release sched_spinlock, the thread object pointer
is never dereferenced by the kernel again; join waiters
or fn_abort() logic may free it immediately.

An assertion added to z_thread_single_abort() to ensure
it never gets called with thread == _current outside of an ISR.

Some logic has been added to ensure z_thread_single_abort()
tasks don't run more than once.

Fixes: #26486
Related to: #23063 #23062

was not used by anything else. The custom trace points unfortunatly were
not accurate and this test was delivering informatin that conflicted
with other tests we have due to placement of such trace points in the
architecture and kernel code.

For such measurements we are planning to use the tracing functionality
in a special mode that would be used for metrics without polluting the
architecture and kernel code with additional tracing and timing code.

Furthermore, much of the assembly code used had issues.

ef224ce1cd ARC: make the assembly codes compatible
Make the assembly codes compatible with both GNU
and Metaware toolchain.

* replace ".balign" with ".align"
  ".align" assembler directive is supposed by all
  ARC toolchains and it is implemented in a same
  way across ARC toolchains.
* replace "mov_s __certain_reg" with "mov __certain_reg"
  Even though GCC encodes those mnemonics and even real
  HW executes them according to PRM these are restricted
  ones for mov_s and CCAC rightfully refuses to accept
  such mnemonics. So for compatibility and clarity sake
  we switch to 32-bit mov instruction which allows use
  of all those instructions.
* Add "%%" prefix while accessing registers from inline
  ASM as it is required by MWDT.
* Drop "@" prefix while accessing symbols (defined in C
  code) from ASM code as it is required by MWDT.

1972f0b7f4 ec_host_cmd: add ec host command handler framework
Add a generic host command handler framework that allows users to
declare new host command handlers with the HOST_COMMAND_HANDLER macro
at build time. The framework will handle incoming messages from the
host command peripheral device and forwards the incoming data to the
appropriate host command handler, which is looked up by id.

The framework will also send the response from the handler back to the
host command peripheral device. The device handles sending the data on
the physical bus.

This type of host command communication is typically done on an embedded
controller for a notebook or computer. The host would be the main
application processor (aka AP, CPU, SoC).

76119c526e Bluetooth: GATT: Allow application to add subscription.
Allow the application to add subscription without resubscribing.
This is needed for persistent bonds that can go to deep sleep and
turn of the RAM or power-cycle.
In this case the application as a GATT client must have a way to add
the subscription callbacks back to the stack before the GATT server
sends notifications.
This should preferable be able to be done before even connecting
since the notifications can arrive immediately after connecting to
the peer.
The stack cannot persist this on it's own since it must remember the
function pointers for the callback functions. Storing these in
persistent storage would not be compatible with a Device Firmware

7d32e9f9a5 mmu: support only identity RAM mapping
We no longer plan to support a split address space with
the kernel in high memory and per-process address spaces.
Because of this, we can simplify some things. System RAM
is now always identity mapped at boot.

We no longer require any virtual-to-physical translation
for page tables, and can remove the dual-mapping logic
from the page table generation script since we won't need
to transition the instruction point off of physical
addresses.

CONFIG_KERNEL_VM_BASE and CONFIG_KERNEL_VM_LIMIT
have been removed. The kernel's address space always
starts at CONFIG_SRAM_BASE_ADDRESS, of a fixed size
specified by CONFIG_KERNEL_VM_SIZE.

Driver MMIOs and other uses of k_mem_map() are still
virtually mapped, and the later introduction of demand
paging will result in only a subset of system RAM being
a fixed identity mapping instead of all of it.

5408f3102d debug: x86: Add gdbstub for X86
It implements gdb remote protocol to talk with a host gdb during the
debug session. The implementation is divided in three layers:

1 - The top layer that is responsible for the gdb remote protocol.
2 - An architecture specific layer responsible to write/read registers,
    set breakpoints, handle exceptions, ...
3 - A transport layer to be used to communicate with the host

The communication with GDB in the host is synchronous and the systems
stops execution waiting for instructions and return its execution after
a "continue" or "step" command. The protocol has an exception that is
when the host sends a packet to cause an interruption, usually triggered
by a Ctrl-C. This implementation ignores this instruction though.

This initial work supports only X86 using uart as backend.

Emulators are used to emulate hardware devices, to support testing of
various subsystems. For example, it is possible to write an emulator
for an I2C compass such that it appears on the I2C bus and can be used
just like a real hardware device.

Emulators often implement special features for testing. For example a
compass may support returning bogus data if the I2C bus speed is too
high, or may return invalid measurements if calibration has not yet
been completed. This allows for testing that high-level code can
handle these situations correctly. Test coverage can therefore
approach 100% if all failure conditions are emulated.

ebe51e26cb ARCH: COMMON: split sys_io.h for MMIO & memory bits functions
As of today 'include/arch/common/sys_io.h" has generic implementation
for MMIO accessors and memory bits manipulation functions. That leads
to several architectures like ARC, ARM/aarch64, ARM/aarch32/corter_a_r
redefine entire 'common/sys_io.h' even if they only have different
MMIO accessors implementation.

So split 'include/arch/common/sys_io.h" to
 * sys_io.h - generic MMIO accessors
 * sys_bitops.h - generic memory bits manipulation functions

99a268fa16 arch: arm: Collect full register state in Cortex-M Exception Stack Frame
To debug hard-to-reproduce faults/panics, it's helpful to get the full
register state at the time a fault occurred. This enables recovering
full backtraces and the state of local variables at the time of a
crash.

This PR introduces a new Kconfig option, CONFIG_EXTRA_EXCEPTION_INFO,
to facilitate this use case. The option enables the capturing of the
callee-saved register state (r4-r11 & exc_return) during a fault. The
info is forwarded to `k_sys_fatal_error_handler` in the z_arch_esf_t
parameter. From there, the data can be saved for post-mortem analysis.

To test the functionality a new unit test was added to
tests/arch/arm_interrupt which verifies the register contents passed
in the argument match the state leading up to a crash.

b37ea90335 drivers: led: add driver for TI LP503x controllers
This patch adds support for the Texas Instruments LP5030 and LP5036
I2C LED controllers. They are respectively providing up to 30 and 36
channels (i.e. 10 or 12 RGB LEDs).

In addition to the channel/color registers this LED controller provides
a per-LED brigthness register. This driver implements both LED-based and
channel-based API methods:

- led_on
- led_off
- led_get_info
- led_set_brightness
- led_set_color
- led_set_channel
- led_write_channels

f59abf5916 drivers: led: introduce channel-dedicated syscalls
Some LED controllers are connected to a large number of LEDs (i.e.
array/strip of LEDs). A user may need to set several LEDs at the same
time. The LED oriented syscalls are not adapted to this task. Indeed a
call per LED is needed to configure a group of LEDs. To that end, this
patch adds the led_set_channel and led_write_channels syscalls to the
LED API. They offer direct access to the raw channels. They respectively
allow to set a single channel and to write several contiguous channels
(and therefore to configure a group of LEDs).

Moreover the addition of the led_write_channels syscall also aims at
closing the gap with the LED strip API.

4f5583bf33 drivers: led: make more API callbacks optional
For the LED controller without any hardware blinking capability this
doesn't really make sense to make the blink callback mandatory. It is
better to let it undefined. This way this will allow the LED API to
fall back to a common software blink implementation.

In addition some controllers with RGB LEDs don't have the capability
to configure the LED brightness but only the channel/color levels.
Their drivers may only implement the set_color callback.

That's why this patch makes the blink and set_brightness LED API
callbacks optional.

The led_set_color syscall adds support for multicolor (i.e.

this array must provide an entry per color/channel and must also be
ordered following the color mapping of the LED. This color mapping can

driver itself (by using the led_get_info syscall).

38e17b68e3 x86: paging code rewrite
The x86 paging code has been rewritten to support another paging mode
and non-identity virtual mappings.

 - Paging code now uses an array of paging level characteristics and
   walks tables using for loops. This is opposed to having different
   functions for every paging level and lots of #ifdefs. The code is
   now more concise and adding new paging modes should be trivial.

 - We now support 32-bit, PAE, and IA-32e page tables.

 - The page tables created by gen_mmu.py are now installed at early
   boot. There are no longer separate "flat" page tables. These tables
   are mutable at any time.

 - The x86_mmu code now has a private header. Many definitions that did
   not need to be in public scope have been moved out of mmustructs.h
   and either placed in the C file or in the private header.

 - Improvements to dumping page table information, with the physical
   mapping and flags all shown

 - arch_mem_map() implemented

 - x86 userspace/memory domain code ported to use the new
   infrastructure.

 - add logic for physical -> virtual instruction pointer transition,
   including cleaning up identity mappings after this takes place.

a542de46ac net: l2: ppp: add initial support for PAP authentication
This patch implements optional authentication phase, which is done
between link establishment and network phases. It is part of LCP option
negotiation to decide whether authentication is needed and which
protocol will be used. For now we add only PAP support and try to
negotiate it when some other protocol (e.g. CHAP or EAP) is proposed
earlier. For simplicity reason we only add one way authentication
support, which means that we try to authenticate to the other peer, but
do not require authentication from it.

This is an important step to make PPP work with cellular network modems,
because most of them require to provide username and password within PPP
authentication phase. Those credentials are used by modem to login to
cellular network. In most cases however it is enough to provide dummy
values, because they are not verified. For this reason and simplicity of
this patch we hardcode PAP Peer-ID and Password now.

13f96d439e sys: onoff: support clients using synchronous transitions
The on-off manager infrastructure is designed to robust asynchronous
transition between binary states where multiple clients may be
initiating a transition from any context.  The actual transition is
performed using a manager that tracks the current state and pending
operations.  Requests are initiated by passing a reference to an
onoff_client object that holds client state including the notification
mechanism.

This API may be used in subsystems where the transitions for a
particular driver are always synchronous and isr-ok, e.g. setting a
SoC-controlled GPIO.  In this situation the full on-off manager
infrastructure is wasteful.  All we need is a record of the service
state: off, active count, or error.

Add a data structure and an API that can be used to replace the onoff
manager functionality in a situation where all transitions are isr-ok
and synchronous while retaining compatible behavior from the client
perspective.

63c3e153d6 drivers: use node IDs for DEVICE_MMIO.*_INIT
There is nothing wrong with instance numbers and they are
recommended for use whenever possible, but this is an API
design problem because it's not always possible to get nodes
by instance number; in some cases, drivers need to get node
identifiers from node labels, for example.

Change these APIs (which are not yet in any Zephyr release)
to take node IDs instead of instance IDs.

236759b18a Bluetooth: controller: Add advertising set handle mapping
Core 5.2, Vol 4, Part E, section 5.3.1 clarifies that advertising set
handle is assigned by host when advertising set is created and this
happens only on LE Set Extended Advertising Parameters.

An advertising set handle is an arbitrary number within allowed range,
i.e. 0x00-0xEF and not 0..max_supported-1.

This patch adds option to enable advertising set handle mapping from
HCI range as defined by Core specification to zero-based handles used
by LL. If enabled, HCI handle will be remapped to LL handle for each
command, otherwise HCI handle will be used as an LL handle. The latter
effectively skips mapping logic and should be used with Zephyr host
which uses zero based indexes.

cabbd916cf drivers: move eeprom_slave driver to tests directory
This device isn't an actual hardware driver: it's a virtual EEPROM
that stores data in an instance-specific RAM buffer, with the data
exposed on an I2C bus as a I2C follower (slave) device that can be
controlled by another device acting as a leader (master) on that same
bus.

As such it's a reasonable example of how to write an I2C follower
driver, but it's not clear that it has a real use in applications.  A
Zephyr application that needs to emulate an EEPROM in a real-world
system would be unlikely to provide its data from a RAM buffer.

The sole in-tree reference is in the i2c_slave_api test, so move the
driver implementation into that test.

The Kconfig and hierarchy are being left in place until it is more
clear how this functionality should be selectable within Zephyr.  The
I2C_SLAVE symbol has been converted from menuconfig to config to
eliminate a Kconfig style diagnostic.

a8cd162d2c device: Rename config_info attribute to config
There use to be a config attribute of type device_config, on which
config_info could be found. config_info was thus named that way to
differentiate easily from config attribute in struct device.

Now that there is no such device_config structure, config_info in
structure device now, can be renamed to config.

Semantically, it makes for sense. We have an attribute pointing to the
configuration of the device driver instance. Configuration information
is correct but has a redundant meaning.

5b034e103f bluetooth: hci_driver: Add BT_QUIRK_NO_AUTO_DLE
Some controllers do not follow the recommendation of auto-initiating
a data length update if the host writes default data length parameters.

If the controller follows this recommendation, calling
LE Write Suggested Default Data Length command is sufficient
to ensure that the LL will auto-initiate the DLE procedure. Performing
a second procedure is unecessary.

In Core v5.2, Vol 4, Part E, Section 7.8.35:
The HCI_LE_Write_Suggested_Default_Data_Length command allows the
Host to specify its suggested values for the Controller's maximum
transmission number of payload octets and maximum packet
transmission time for packets containing LL Data PDUs to be used
for new connections. The Controller may use smaller or larger values
for connInitialMaxTxOctets and connInitialMaxTxTime based on local
information.

In short, this command sets connInitialMaxTxOctets
and connInitialMaxTxTime.

In Core v5.2, Vol 6, Part B, Section 4.5.10:

For a new connection: connMaxTxOctets shall be set to
connInitialMaxTxOctets and connMaxRxOctets shall be chosen by the
Controller. If either value is not 27 then the Controller should
initiate the Data Length Update Procedure at the earliest practical
opportunity.
