There are x86 platforms where the IRQ configuration register for PCIe
is not pre-populated and the OS needs to assign a number dynamically
by writing to the register.
In order to allocate interrupts we have to know which ones have been
hard-coded in device tree. We accomplish this by collecting these
values through the IRQ_CONNECT() macro and placing them in a dedicated
linker section (in ROM).
The full set of allocated interrupts are managed through a bitmap, and
the pre-allocated values (from the linker section) are inserted into
this upon initial runtime access.
This patch introduces a new pcie_alloc_irq() API that drivers can use
to allocate interrupt line numbers. The two in-tree drivers that were
using this API (I2C and UART) are converted to use the new API.

SPARC is an open and royalty free processor architecture.
This commit provides SPARC architecture support to Zephyr. It is
compatible with the SPARC V8 specification and the SPARC ABI and is
independent of processor implementation.
Functionality specific to SPRAC processor implementations should
go in soc/sparc. One example is the LEON3 SOC which is part of this
patch set.
The architecture port is fully SPARC ABI compatible, including trap
handlers and interrupt context.
Number of implemented register windows can be configured.
Some SPARC V8 processors borrow the CASA (compare-and-swap) atomic
instructions from SPARC V9. An option has been defined in the
architecture port to forward the corresponding code-generation option
to the compiler.
Stack size related config options have been defined in sparc/Kconfig
to match the SPARC ABI.

This commit adds a C99 stdio value formatter capability where

The formatter supports most C99 specifications, excluding:
* %Lf long double conversion
* wide character output
Kconfig options allow disabling features like floating-point
conversion if they are not necessary. By default most conversions are
enabled.

Fix the issue where the kernel poll code would place the tracking
struct on the caller stack and share it with other threads, thus
creating a cache coherence issue on systems where KERNEL_COHERENCE is
enabled.
This works by eliminating the thread backpointer in struct _poller and
simply placing the (now just two-byte!) struct directly into the
thread struct.
Note that this doesn't attempt to fix the API paradigm that the
natural way to structure a call to k_poll() is to use an array of
k_poll_events on the CALLER's stack. So it's likely that most
"typical" k_poll code is still going to have problems with
KERNEL_COHERENCE. But at least now the kernel internals aren't
fundamentally broken.

The poll code was playing this weird trick where the thread pointer in
the "struct _poller" object for a triggered work item. It would not
be a thread to wake up, but instead a pointer to the (non-polling)
thread operated by the work queue being triggered. The code would
never touch this thread, just use it as a way to get a pointer to the
enclosing work queue struct.
Just store the work queue pointer in the first place. It's much
simpler, and makes future modifications to remove that thread pointer
possible.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The triggered work scheme uses a trick where it overloads the thread
pointer field of the struct poller (which normally stores the ID of
the thread that is blocked in k_poll()) to be able to find the work
queue to which it will submit.
Give it its own pointer field to break this false dependency.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
Somewhat weirdly, k_poll() can do one of two things when the set of
events is signaled: it can wake up a sleeping thread, or it can submit
an unrelated work item to a work queue. The difference in behaviors
is currently captured by a callback, but as there are only two it's
cleaner to put this into a "mode" enumerant. That also shrinks the
size of the data such that the poller struct can be moved somewhere
other than the calling stack.

Change the advertising option that controls if the directed advertiser
will use an RPA or the identity address of the peer for the initiator
address.
This option currently has two issues:
- It behaves differently if the privacy feature has been enabled,
which can be confusing for application to use.
- It cannot start a directed advertiser towards a peer that is not
privacy-enabled and has distributed an IRK.
This commit includes the following changes:
- When privacy has been enabled in order to advertise towards a
privacy-enabled peer the BT_LE_ADV_OPT_DIR_ADDR_RPA option must now
be set (same as when privacy has been disabled).
- It is now possible to start a directed advertiser using the identity
address of the peer when privacy-enabled.
- When privacy has been enabled the advertising option combination
of using the local identity address and an RPA as the initiator
address is now disallowed and will return an error code.
This is done because this combination did not actually work and would
have used the identity address of the peer instead.
- If the controller does not support controller-based privacy then
using the option BT_LE_ADV_OPT_DIR_ADDR_RPA will return ENOTSUP
because this behavior cannot be done with host-based privacy.

Previously, ring buffer had capacity of provided buffer size - 1. This
trick was used to distinguish between empty and full states. It had one
drawback: ring buffer could not be used as a pool of equal sized buffers
(using ring_buf_put_claim and ring_buf_get_claim).
Reworked internals to use non wrapping head and tail. Since they are
non wrapping, there is no issue with distinguishing between empty and
full. Since this appraoch would be vulnerable to wrapping on 32 bit
boundary, added a mechanism which periodically reduces all indexes to
avoid 32 bit wrapping.
After this rework, buffer has one byte more capacity. Simple test shows
slight performance improvement.
Updated tests to reflect increased capacity and added test to check if
it is possible to continuesly allocated 2 buffers of half ring buffer

Currently, the Zephyr LwM2M code base is littered with hard-coded
object- and resource IDs, such as
/* Mark 1st instance of security object as a bootstrap server */
lwm2m_engine_set_u8("0/0/1", 1);
The purpose of this LoC is extremely opaque without the accompanying
comment. Each use of a resource path requires constantly checking
headers or the object registry to ensure you're not misremembering IDs.
To alleviate this, this commit introduces a variadic LwM2M path
expansion macro which performs preprocessor stringification on each
argument. For instance, "0/0/1" can now be written as
LWM2M_PATH(LWM2M_OBJECT_SECURITY_ID, 0, SECURITY_BOOTSTRAP_FLAG_ID)
which, while albeit lengthier, avoids the use of hard-coded string
literals, thus making the code much more immediately understandable.

Currently, when socket errors occur during receive, the LwM2M engine
restarts the state machine and registers again to the server. While this
works in simple use case (only RD client socket open), it's not a valid
approach when more sockets are open (FW update socket).
Fix this by introducing socket fault callback, which is registered by
the LwM2M engine users. This way, a proper socket owner is notified on
error and can pertake appropriate action.
For RD socket errors the behaviour remains the same - the state machine
is reset and the client registers again to the server. For FW update
socket, handle the error by reopening the socket and retransmitting the
last request. This allows to resume the download from the point the
error occured, w/o a need to start from scratch.

This is somewhat obscure and has no supporting APIs or
overview documentation and should be considered a private
kernel feature. Applications should really be using
k_thread_join() instead.

k_mem_domain objects should not be initialized multiple times,
there's no support for memory domain life-cycles or freeing
memory that an arch_mem_domain_init() may have allocated.
Clearly document this.
The init function has to assume the provided domain is un-
initialized memory so it's not possible to robustly check
for this; a note is left in the arch_ definition to add an
assertion if feasible.
It's really unsafe to call an init function on any kernel
object more than once, but in this particular case if the
memory domain initialization resulted in the creation of
page tables or linked data structures really bad things can
happen. Currently no arch implements arch_mem_domain_init()
yet, but this is changing soon for x86.
One test case currently does this, it will be fixed in
a forthcoming patch.

Improve the documentation of the UUID header by adding documentation
for all helper macros.
Be explicit in which macros that expects host endianness, and which
ones that expects little endian format.

This is a major refactoring of the handling of the cryptographic
material of both the network and transport layers. The aim is to
encapsulate the key object manipulation, and improve overall modularity.
Pulls Applications and Subnets out of the bt_mesh and into separate
modules, with static storage types on the data. This has several
side-effects:
- The Config Server no longer operates directly on the bt_mesh.subs and
bt_mesh.apps lists, but goes through a public configuration interface,
following the pattern set in #27908.
- All iteration through the keys is done through iteration APIs
- Key resolution on RX and TX is centralized.
- Changes to the keys triggers events the other modules can register
handlers for.
- Friendship credentials are stored in the lpn and friend structures.
Part of #27842.
