There are legitimate cases where both ARCH_THREAD_STACK_SIZE_ADJUST()
and ARCH_THREAD_STACK_RESERVED() may be defined at the same time.
It is important for the former to be exposed to the later in that case,
so add K_THREAD_STACK_RESERVED to the argument instead of the result.
Similarly for Z_THREAD_STACK_OBJ_ALIGN() which needs the adjusted size
to provide the proper result. That's what K_THREAD_STACK_LEN() does
already anyway, so fold Z_THREAD_STACK_SIZE_ADJUST() into the definition
of Z_THREAD_STACK_OBJ_ALIGN() directly.

This adds lazy floating point context switching. On svc/irq entrance,
the VFP is disabled and a pointer to the exception stack frame is saved
away. If the esf pointer is still valid on exception exit, then no
other context used the VFP so the context is still valid and nothing
needs to be restored. If the esf pointer is NULL on exception exit,
then some other context used the VFP and the floating point context is
restored from the esf.
The undefined instruction handler is responsible for saving away the
floating point context if needed. If the handler is in the first
irq/svc context and the current thread uses the VFP, then the float
context needs to be saved. Also, if the handler is in a nested context
and the previous context was using the FVP, save the float context.

The original design intent with arch_sched_ipi() was that
interprocessor interrupts were fast and easily sent, so to reduce
latency the scheduler should notify other CPUs synchronously when
scheduler state changes.
This tends to result in "storms" of IPIs in some use cases, though.
For example, SOF will enumerate over all cores doing a k_sem_give() to
notify a worker thread pinned to each, each call causing a separate
IPI. Add to that the fact that unlike x86's IO-APIC, the intel_adsp
architecture has targeted/non-broadcast IPIs that need to be repeated
for each core, and suddenly we have an O(N^2) scaling problem in the
number of CPUs.
Instead, batch the "pending" IPIs and send them only at known
scheduling points (end-of-interrupt and swap). This semantically
matches the locations where application code will "expect" to see
other threads run, so arguably is a better choice anyway.

In a first place, the PWM API operates on "channels", not "pins". While
the API calls could have been changed by _channel, this patch takes the
approach of just dropping _pin. The main reason is that all API calls
operate by definition on a channel basis, so it is a bit redundant to
make this part of the name. Because the `_dt` variants of the calls are
going to be introduced soon, the change to `_channels` + `_dt` would
make API function names quite long.

When a stack overflow is caught by an MPU region, the stack pointer will
end up inside that area when the exception is handled. Handling the
exception involves pushing an exception frame onto the same stack. If
there's not enough space remaining below the faulting SP value, the
memory region below the stack will get corrupted.
We protect against this by making the stack guard larger than the 0x20
bytes necessary to hold an exception frame. To avoid lots of conditional
complexity here, the guard is set to 0x40 bytes if the MPU minimum size
is not larger than 0x20 bytes.
Signed-off-by: Keith Packard <keithp@keithp.com>
Making context switch cache-coherent in SMP is hard. The
KERNEL_COHERENCE handling was conservatively invalidating the stack
region of a thread that was being switched in. This was because it
might have (1) run on this CPU in the past, but (2) run most recently
on a different CPU. In that case we might have stale data still in
our local dcache!
But this has performance impact in the (very common!) case of a thread
being switched out briefly and then back in (e.g. k_sleep() for a
small duration). It will come back having lost all of its cached
stack context, and will have to fetch all that information back from
shared SRAM!
Treat this by tracking a "last_cpu" for each thread in the arch part
of the thread struct. If we're coming back to the same CPU we left,
we know we can skip the invalidate.

There is errata clarification (Errata ID:18700)
about subscriptions on fixed group addresses.
It is possible to subscribe models on non primary elements
on any fixed group address except all nodes address.
Devices should be able to receive messages on fixed addresses
even if they do not support the feature
to which the fixed group address belongs.

Add an API that utilizes the ARM semihosting mechanism to interact with
the host system when a device is being emulated or run under a debugger.
RISCV is implemented in terms of the ARM implementation, and therefore
the ARM definitions cross enough architectures to be defined 'common'.
Functionality is exposed as a separate API instead of syscall
implementations (`_lseek`, `_open`, etc) due to various quirks with
the ARM mechanisms that means function arguments are not standard.

When threads are in more than one state at a time, k_thread_state_str()

This in turn necessitates a change to the API that includes both a

In some cases (for examples when offloaded socket implementation does
not implement TLS functionality) it could be desired to create a native
TLS socket with an underlying offloaded socket.
This cannot be achieved with SO_BINDTODEVICE option only, as TLS socket
type is not really associated with a particular interface - it either
has to be offloaded, or a fully native socket is created (native TLS on
a native interface).
In order to address the problem, introduce TLS_NATIVE socket option.
This option instructs the socket dispatcher layer to create a native TLS
socket. As with the socket dispatcher the underlying socket
implementation is not decided during TLS socket creation, therefore it's
possible to use SO_BINDTODEVICE to choose either native or offloaded
interface for the underlying socket.
Additionally remove NET_SOCKETS_OFFLOAD_TLS Kconfig option, as it's no
longer needed with an runtime option to select whether to offload TLS or
not.

Add a separate macro for registering offloaded sockets implementation,

API with an interface.
Signed-off-by: Robert Lubos <robert.lubos@nordicsemi.no>
Instead of keeping a boolean informing whether a network interface is
offloaded at socket layer or not, keep a pointer to a function which
allows to create an offloaded socket. Native interfaces keep this as
NULL, while for offloaded interfaces it allows to connect an offloaded
socket implementation with an interface.

If the sys_slist_t instance is not empty, its head and tail points to
some sys_snode_t instances. If sys_slist_append_list is executed with
tail being NULL the list object is corrupted. Tail of the sys_slist_t
instance is set to NULL. If one executes sys_slist_append on that node,
then nodes pointed by head are lost.
The commit fixes the issue and adds unit tests to verify correct
behavior.
Added change verifies if head and tail of appended list are not NULL.
In other case the list object is invalid and should not be appended
to a valid list instance.

CAN in Automation (CiA) 301 v4.2.0 recommends a sample point location of
87.5% percent for all bitrates. However, some CAN controllers have
difficulties meeting this for higher bitrates.
Change can_set_bitrate() to use a sample point of 75.0% for bitrates
over 800 kbit/s, 80.0% for bitrates over 500 kbit/s, and 87.5% for all
other bitrates. This is in line with the sample point locations used by
the Linux kernel.
Regard a sample point error of more than +/- 5.0% as an error in setting
the bitrate. Previously, any sample rate error was accepted without
providing any feedback to the caller. This is in line with the CAN
sample point calculation criteria used by the Linux kernel.

There are two aspects to this: CPU registers are twice as big, and the
load and store instructions must use the 'd' suffix instead of the 'w'
one. To abstract register differences, we simply use a ulong_t instead
of u32_t given that RISC-V is either ILP32 or LP64. And the relevant
lw/sw instructions are replaced by LR/SR (load/store register) that get
defined as either lw/sw or ld/sd. Finally a few constants to deal with
register offsets are also provided.

This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t. This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.
We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.
We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.
