When CONFIG_KERNEL_COHERENCE=y (e.g on the various intel_adsp
platforms under SMP) it's not legal to share stack memory between
CPUs, because the stack is cached, and the L1 cache is incoherent.
The kernel will automatically detect the mistake when the memory
contains a kernel object (spinlock, IPC object, etc...). But here the
test was just passing async buffers into the msgq layer, and nothing
watches that.
The fix is simple: make them static.

There might be a sign extension when a long is promoted to
int_value_type and the former type is smaller than the later.
This produces the wrong output if the specified format is unsigned.
Let's avoid this problem by handling signed and unsigned cases
explicitly. When the type already matches int_value_type then the
compiler is smart enough to recognize the redundancy and removes
unneeded duplications automatically, meaning that the code will stay
small when code size matters.
A similar issue also existed in the restricted %llu case.
The fix is the same as above.

The stack array tstacks was declared in the header file using
the same macro which defines the same stack array but with
an added "extern" in front. This macro adds alignment and section
attribute which are actually not the same as the actual stack array
defined in main.c. The section name used in the section attribute
contains the file name where the stack array is defined or extern
declared. So the same symbol, in this case z_interrupt_stacks, has
different attributes in two places, and GCC 11 starts to complain
about this. So use the newly introduced macro to extern declare

Every va_start() currently triggers a FPU access trap if FPU is not
already used. This is due to the fact that va_start() must copy FPU
registers that are used for float argument passing into the va_list
object. Flushing the FPU context to its owner and granting access to
the current thread is wasteful if this is only for va_start(),
especially since in most cases there are simply no FP arguments
being passed by the caller.
This is made even worse with exception code (syscalls, IRQ handlers,
etc.) where the exception code has to be resumed with interrupts
disabled upon FPU access as there is no provision for preserving an
interrupted exception mode's FPU context.
Fix those issues by simply simulating the sequence of STR instructions
that the va_start() generates without actually granting FPU access.
We limit ourselves only to exception context to keep changes to a
minimum for now.
This also allows for reverting the ARM64 exception in the nested IRQ
test as it now works properly even if FPU_SHARING is enabled.

will obviously schedule other threads to run in a context where the
code was promised it would not. This used to be an uncaught error,
but now we have an assertion that catches this.
It's not clear what this test case is supposed to be testing, as the
behavior is actually identical to the release_global_lock case except
for the (incorrect) addition of the irq_lock(). If this is needed for
code coverage we can work to figure out the real root cause of the

Kernel objects that contain embedded synchronization structures like
spinlocks can't be palced in the (cached/incoherent) stack memory on

two objects (i.e. you can't put a "static" in front of it as with

First, this test is a little suspect. It's assuming that the value
returned from k_cycle_get_32() represents the time since system
power-on. While that's an obvious implementation choice and surely
often true, it's definitely not the way we document this API to the
arch layer. It's perfectly legal for a platform to return any value
as long as the counter is increasing at the correct rate. Leaving for
now as there's no other way to test CONFIG_BOOT_DELAY, but this will
likely be coming back to confuse us at some point.
Regardless, that convention holds for x86 devices using any of the
existing drivers. But on an EFI PC using the TSC counter as the clock
source: (1) the counter is running at 1-2 GHz and (2) the time to get
through an EFI BIOS and into Zephyr is routinely 10+ seconds,
especially on reference hardware. The poor 32 bit API will roll over
several times, and effectively be a random number by the time it
reaches this test.
Just skip this test with fast counter.

This adds FPU sharing support with a lazy context switching algorithm.
Every thread is allowed to use FPU/SIMD registers. In fact, the compiler
may insert FPU reg accesses in anycontext to optimize even non-FP code
unless the -mgeneral-regs-only compiler flag is used, but Zephyr

The original implementation of resubmitting a delayed work item
removed the item not only from the schedule, but also from the work
queue if it was already in the work queue. This is not the semantics
of the new implementation, which will leave the work item in the queue
if the previous deadline had elapsed and the work item was submitted.
The new semantics is preferred, as it improves consistency with SMP
targets where once an item has been submitted to a queue it can be run
at any time, and scheduling it again doesn't magically reverse the
submission. The original test would never have passed on an SMP
target, and passes now on qemu_x86 only because the timing granularity
prevents the work item from being both scheduled and queued at the
same time.
The problematic test application is the one developed for the original
implementation. Correct functioning of the new implementation is
fully verified by the sibling work test. That the legacy API does not
precisely preserve the original behavior where it was not consistent
between SMP and uniprocessor targets is regrettable, but unavoidable.

of races against real time, so it simply validated that the test
started at or later than the expected timeout expiration.
But when calculating the expected time, it called k_uptime_ticks()
AFTER the timeout was registered. So on systems with fast ticks (or

The new API cannot be used from userspace because it is not merely a

work queue users are operating from privileged mode, so there's little
motivation to go through the pain and complexity of converting all
functions to system calls.
Copy the necessary pieces of the existing userspace work queue API out
and expose them with new names and types:
* k_work_handler_t becomes k_work_user_handler_t
* k_work becomes k_work_user
* k_work_q becomes k_work_user_q

names are also introduced to make it more clear that the userspace
work queue API is a separate functionality.

The test_timeout_abs case had baked in similar mistakes to the
off-by-one in the absolute timer implementation. FOR THE RECORD:
If you have an absolute timeout expiration set for a tick value "N",
and the current time returned by k_uptime_ticks() is "T", then the
time returned (at the same moment) by any of the *_remaining_ticks()
APIs must ALWAYS AND FOREVER BE EXACTLY "N - T" (also: "N - T > 0"
always, until the moment the kernel ISR hands off control to the first
timeout handler expiring at that tick).
The tick math is exact. No slop is needed on any systems, no matter
whether their clocks divide by milliseconds or not.
The only gotcha is that we need to be sure that the calls don't
interleave with a real time tick advance, which we do here with a
simple retry loop.
But, about slop... This patch also includes a related fix for the
test_sleep_abs(). On an intel_adsp (which has 50 kHz ticks, a
comparatively slow idle resume and interrupt entry, and even has two
CPUs to mess with latency measurements) I would occasionally see the
k_sleep() take more than a tick to wake up from the interrupt handler
until the return to application code. Add some real time slop there
(just 100us) to handle systems like this.

When the kernel is TICKLESS, timeouts are set as needed, and drivers
all have some minimum amount of time before which they can reliably
schedule an interrupt. When this happens, drivers will kick the
requested interrupt out by one tick. This means that it's not
reliably possible to get a timeout set for "one tick in the
future"[1].
And attempting to do that is dangerous anyway. If the driver will
delay a one-tick interrupt, then code that repeatedly tries to
schedule an imminent interrupt may end up in a state where it is
constantly pushing the interrupt out into the future, and timer
interrupts stop arriving! The timeout layer actually has protection
against this case.
Finally getting to the point: in recent changes, the timeslice layer
lost its integration with the "imminent" test in the timeout code, so
it's now able to run into this situation: very rapidly context
switching code (or rapidly arriving interrupts) will have the effect
of infinitely[2] delaying timeouts and stalling the whole timeout
subsystem.
Don't try to be fancy. Just clamp timeslice duration such that a
slice is 2 ticks at minimum and we'll never hit the problem. Adjust
the two tests that were explicitly requesting very short slice rates.
[1] Of course, the tradeoff is that the tick rate can be 100x higher
or more, so on balance tickless is a huge win.
[2] Actually it only lasts until a 31 bit signed rollover in the HPET
cycle count in practice.

When calculating the expected interval for threads other than
the first one, the test uses ms->ticks->cycles conversion to
figure out the bound of cycles permitted. Both lower and upper
bound conversions are using the k_*_to_*_floor32(). When
numbers involved are not wholly divisible, decimal points are
being truncated, resulting in incorrect intervals, and thus
failing tests. So change the calculation to appropriate
floor() or ceil() based on the boundary.

Correct a bunch of precision/analysis errors in this test:
* Test items weren't consistent about tick alignment and resetting of
the timestamp, so put these steps into init_timer_data() and call
that immediately before k_timer_start().
* Many items would calculate the initial timestamp AFTER
k_timer_start(), leading to an extra (third!) point where the timer
computation could alias by an extra tick. Always do this
consistently before the timer is started (via init_timer-data()).
* Tickless systems with high tick rates can easily advance the system
uptime while the timer ISR is running, so the system can't expect
perfect accuracy even there (this test was originally written for
ticked systmes where the ISR was by definition happening "at the
same time").
(Unfortunately our most popular high tick rate tickless system,
nRF5, also has a clock that doesn't divide milliseconds exactly, so
it had a special path through all these precision comparisons and
avoided the bugs. We finally found it on a x86 HPET system with 10
kHz ticks.)
* The interval validation was placing a minimum bound on the interval
time but not a maximum (this mistake was what had hidden the failure
to reset the timestamp mentioned above).
Longer term, the millisecond precision math in these tests is at this
point an out of control complexity explosion. We should look at
reworking the core OS tests of k_timer to use tick precision (which is
by definition exact) pervasively and leave the millisecond stuff to a
separate layer testing the alternative/legacy APIs.

A fairly common idiom in our test code is to put test-local data

means that such things may not get a consistent view of memory between
threads.
Just make these things static. A few of these spots were causing test

Thread stack memory on coherence platforms needs to be linked into a
special section (so it can be cached).
Also, the test_idle_stack case just can't work with coherence. It's
measuring the CPU's idle stack's unused data, which was initialized at
boot from CPU0, and not necessarily the CPU on which the test is
running. In practice on intel_adsp_cavs15, our CPU has stale zeroes
in the cache for its unused stack area (presumably from a firmware
memory clear at boot or something?). Making this work would require a
cache invalidate on all CPUs at boot time before the idle threads
start, we can't do it here in the test because we don't know where the
idle stack pointer is.
Too much work for an esoteric stack size test, basically. Just
disable on these platforms.

The deadline scheduler as of commit ef626571b2 ("kernel/sched:
Optimize deadline comparison") got an optimization that requires that
the the cycle difference of the deadline time of the "first" and
"last" runnable thread never be higher than 2^31.
The test code here was masking off the bottom 31 bits of the generated
deadlines, so it looked OK. But because the actual setting of the
deadline values takes time too, it was still possible to select values
that would roll over. The window was VERY small, but the RNG on one
platform (up_squared) hit it.
Shrink the selected deadlines to live in a 30 bit space for safety.

The inheritance test first creates a parent thread, and then
creates a child thread inside this parent thread. At the same
time inside the main thread, a resource pool is assigned to
the parent thread. However, when under SMP, it is possible
that the pool assignment is done between both parent/child
threads are getting pointers to the pool, due to multiple
threads are running. So when doing pool pointer comparison,
there is a mismatch between those pointers (like parent has
a null pool pointer while child is pointing to the actual
pool), and thus failing the test. So fix this by delaying
the parent from running under after pool assignment is done.

When coverage is enabled on x86_64, GCC uses relative addressing
to increment the gcov counters. The generated code of the test
function assumes execution is in the same location where
the linker places the test function. This does not work with
the execution test as it copies the function into another part
of memory and tries to execute from there. When the copied
function starts to run, the instruction pointer is at the newly
copied function. So any relative addressing with regard to
the instruction pointer now is invalid. Instead of
<generated code RIP + offset> for gcov counter as it should be,
now the copied code is trying to access the counter at
<copied code RIP + offset>, which points to incorrect
memory location (and possibly invalid/non-mapped memory).
To fix this, we need to tell GCC not to use relative addressing.
This can be accomplished by telling GCC to use the large memory
model. This is only used for this test as this option increases
code size quite a bit, and should not be used in general.

Upcoming changes from Andrew that add a global timeout to the kernel
broke because of some voodoo behavior in the kernel/context test. It
will use arch_irq_disable() on the timer interrupt directly to prevent
interrupts and measure timekeeping in their absence. But some
architectures[1] don't reliably deliver interrupts that arrive, which
means that a running timeout that exists across this period will
result in a corrupt timeout queue.
Document that rule for architectures, move the offending test to the
end of the test suite (to minimize the chance of interacting with
other test code) and put a giant warning about the situation on it.
Long term, we may want to rework this test to do its job in other
ways.
[1] On x86, the interrupt disable happens at the IO-APIC level, while
interrupt latching and delivery is downstream in each CPU's Local
APIC. An IO-APIC masked interrupt is completely invisible to the APIC
and can never be delivered once the line goes low.

these to be in a continuous virtual region, and we need to
stop assuming that there is just one SRAM region that is
identity-mapped.
We no longer use CONFIG_SRAM_BASE_ADDRESS and CONFIG_SRAM_SIZE
as the bounds of kernel RAM, and no longer assume in the core
kernel that these are identity mapped at boot.
Two new Kconfigs, CONFIG_KERNEL_VM_BASE and
CONFIG_KERNEL_RAM_SIZE now indicate the bounds of this region
in virtual memory.
We are currently only memory-mapping physical device driver
MMIO regions so we do not need virtual-to-physical calculations
to re-map RAM yet. When the time comes an architecture interface
will be defined for this.
Platforms which just have one RAM region may continue to
identity-map it.

This test is a little subtle: it wants to spawn three threads to run
and be switched out by a timeslice interrupt. And it wants to consume
half a time slice itself before it starts running. And, because
timeslicing runs out of the same tick framework in the timer driver,
it needs to align to the start of a tick before the process starts.
And further: it does its own time math not in ticks but in timer
cycles, so it's quite sensitive to slop.
But it's "synchronize to tick boundary" code was actually
synchronizing to a CYCLE boundary, which is just wrong. And it was
doing this in the wrong order. It was resetting the timeslice first
and then synchronizing to a tick by spinning, which means that the
test was always going to begin as much as a tick late. Do the tick
synchronization (via a sleep) first.
Finally, the manager thread that was spawning the new threads lives at
the same priority as the highest priority child threads, which means
it can potentitially wake up on the semaphores that they are giving in
the middle of the test and consume CPU unexpectedly. Make sure it's
sleeping for the duration.

2. test_no_ref_dyn_kobj_release_mem()

the permission system will use object permission as a reference count
If no threads have access to an object, the object's memory released.
3. test_krnl_obj_static_alloc_build_time()

The test_triggered_wait_expired test submits the items with
2*SUBMIT_WAIT timeout and waits for the timeout to expire
so the items are being worked on. It waits one SUBMIT_WAIT
and checks none of the items have started. Then waits
another SUBMIT_WAIT to check if they have all finished.
However, since the timeout is at 2*SUBMIT_WAIT, the work
queue may have just started going through the list of items.
This means some items may have started while others have not.
This results in the test failing as not all items have
finished. So lengthen the second sleep to allow items to
finish before checking.

Add new tests to improve of the Zephyr QA testing of the memory
protection for memory domains and partitions.
I created new tests for memory protection->memory partitions for
the requirements which I think necessary to be tested.
I added Doxygen tag for each test to make it clear to understand
what each test is doing and how.
New tests for memory domains and partitions:
-test_mem_domain_api_kernel_thread_only()
By creating that test I wanted to prove that access to memory
domain APIs must be restricted only to supervisor threads.
At the same time I wanted to prove that system can support the
definition of memory domains.
-test_mem_part_auto_determ_size()
By creating that test I want to prove that system can automatically
determine application memory partition base addresses and sizes
at build time, determined by its contents. Also system can support
definition of memory partitions. At the same time test proves that OS
supports adding and removing a thread from its memory domain
assignment.
-test_mem_part_auto_determ_size_per_mmu()
That test is very important and it proves that memory partitions are
automatically sized and aligned per the constraints of the platform's
memory management hardware.
-test_mem_part_inheirt_by_child_thr()
Prove that child thread inherits memory domain assignment of its
parent.
-test_macros_obtain_names_data_bss()
Test system provides tools to obtain the names of the data and BSS
sections related to a particular application memory partition at
build time.
-test_mem_part_assign_bss_vars_zero()
Test that global data and BSS values can be assigned to application
memory partitions using macros at build time. Test that BSS values
will be zeroed at the build time.

Add k_delayed_work_pending similar to k_work_pending to check if the
delayed work item has been submitted but not yet completed.
This would compliment the API since using k_work_pending or
k_delayed_work_remaining_get is not enough to check this condition.
This is because the timeout could have run out, but the timeout handler
not yet processed and put the work into the workqueue.

There are predictable relationships between the actual size

These stacks are appropriate for threads that run purely in
supervisor mode, and also as stacks for interrupt and exception
handling.
Two new arch defines are introduced:
- ARCH_KERNEL_STACK_GUARD_SIZE
- ARCH_KERNEL_STACK_OBJ_ALIGN
New public declaration macros:
- K_KERNEL_STACK_RESERVED
- K_KERNEL_STACK_EXTERN
- K_KERNEL_STACK_DEFINE
- K_KERNEL_STACK_ARRAY_DEFINE
- K_KERNEL_STACK_MEMBER
- K_KERNEL_STACK_SIZEOF
If user mode is not enabled, K_KERNEL_STACK_* and K_THREAD_STACK_*
are equivalent.

The core kernel computes the initial stack pointer
for a thread, properly aligning it and subtracting out
any random offsets or thread-local storage areas.
arch_new_thread() no longer needs to make any calculations,
an initial stack frame may be placed at the bounds of
the new 'stack_ptr' parameter passed in. This parameter
replaces 'stack_size'.
thread->stack_info is now set before arch_new_thread()
is invoked, z_new_thread_init() has been removed.
The values populated may need to be adjusted on arches
which carve-out MPU guard space from the actual stack
buffer.
thread->stack_info now has a new member 'delta' which
indicates any offset applied for TLS or random offset.
It's used so the calculations don't need to be repeated
if the thread later drops to user mode.
CONFIG_INIT_STACKS logic is now performed inside
z_setup_new_thread(), before arch_new_thread() is called.
thread->stack_info is now defined as the canonical
user-accessible area within the stack object, including
random offsets and TLS. It will never include any
carved-out memory for MPU guards and must be updated at
runtime if guards are removed.
Available stack space is now optimized. Some arches may
need to significantly round up the buffer size to account
for page-level granularity or MPU power-of-two requirements.
This space is now accounted for and used by virtue of
the Z_THREAD_STACK_SIZE_ADJUST() call in z_setup_new_thread.

1. Found out that thread tests doesn't test next ideas of requirements,
which I think necessary to be tested and verified:
-the kernel need to prevent user threads creating new threads from
using thread or thread stack objects which are in an initialized state
-Upon thread exit, the kernel need to mark the exiting thread
and thread stack objects as uninitialized
Add new tests to test requirements above, that way we can cover more
features to be tested:
- test_new_user_thread_with_in_use_stack_obj()
- test_mark_thread_exit_uninitialized()
2. Modified test test_create_new_thread_from_user() to verify that
kernel provides new user threads access to their own thread object.
3. Also I added detailed Doxygen tags for each new test and existing

4. Added Doxygen tag to the existing test test_stack_buffer, it

-The kernel need to provide all threads read and write access to their

This test was written to assume that the only IPI handled would be the
one generated by the test, but the scheduler also generates an IPI any
time a thread becomes runnable, and there's no way to lock that out in
an SMP system where the other CPU is going to be doing its own thing
(we can't use "1cpu" because that locks interrupts on the other CPU
and obviously this is a test of an interrupt).
Change the logic to detect that "at least one IPI was received", which
is fine for coverage. Really a better place for a test like this
would have been tests/kernel/mp, which is a test of the lower level
APIs and runs the other CPU deterministically (i.e. not under the
control of the Zephyr scheduler).
Also some misc fixes:
* Don't busy wait at the start, that's needless.
* Sleep instead of busywaiting after sending the IPI, spinning isn't
needed here and acts to increase CI load needlessly.
* Declare the cross thread signal variable volatile for correctness
(though this error seems to have been benign in practice).

Add support for 64 bit conversions in a uniformly expressable way by
printing values backwards into a buffer on the stack first. This
allows all operations to work on the low bits of the value and so the
code doesn't need to care (beyond the size of that buffer) about the
word size. This trick also doesn't care about the specifics of the
base value, so in the process this unifies the decimal and hex printk
conversion code to a single function.
This comes at a mild cost in CPU cycles to the decimal converter and
somewhat higher cost to hex (because it's now doing a full div/mod
operation instead of shifting and masking). And stack usage has grown
by a few words to hold the temporary. But the benefits in code size
are substantial (e.g. ~250 bytes of .text on arm32).
Note that this also contains a change to tests/kernel/common to
address what appears to have been a bug in the original converters.
The printk test uses a format string that looks like "%-4x%-2p" and
feeds it the literal arguments "0xABCDEF" and "(char *)42".
Now... clearly both those results are going to overflow the 4 and
2-byte field sizes, so there shouldn't be any whitespace between these
fields. But the test was written to expect two spaces, inexplicably
(yes, I checked: POSIX-compatible printf implementations don't have
those spaces either).
The new code is definitely doing the right thing, so fix the test
instead.

When CONFIG_POLL was set, it was historically true that the queue
could (if a higher priority thread "stole" an insert) return a
spurious NULL instead of continuing to wait on a timeout.
This deliberately exercises that race.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The k_queue data structure, when CONFIG_POLL was enabled, would
inexplicably use k_poll() as its blocking mechanism instead of the
original wait_q/pend() code. This was actually racy, see commit
b173e4353f. The code was structured as a condition variable: using
a spinlock around the queue data before deciding to block. But unlike
pend_current_thread(), k_poll() cannot atomically release a lock.
A workaround had been in place for this, and then accidentally
reverted (both by me!) because the code looked "wrong".
This is just fragile, there's no reason to have two implementations of
k_queue_get(). Remove.
Note that this also removes a test case in the work_queue test where
(when CONFIG_POLL was enabled, but not otherwise) it was checking for
the ability to immediately cancel a delayed work item that was
submitted with a timeout of K_NO_WAIT (i.e. "queue it immediately").
This DOES NOT work with the origina/non-poll queue backend, and has
never been a documented behavior of k_delayed_work_submit_to_queue()
under any circumstances. I don't know why we were testing this.

This commit fixes the assertion in test_timer_remaining() that checks
whether the remaining ticks on a timer is less than or equal to half of
the timer duration after a busy wait of that time. If the timer
duration corresponds to an odd number of ticks, 1 should be added to
the upper bound given k_timer_remaining_ticks() returns
<ticks til next deadline> - <elapsed ticks>,
and <elapsed ticks> is truncated to closest integer tick count.
For example, if
dur_ticks = 3277
<ticks til next deadline> = 3277
<elapsed ticks> = 1638.5 rounded to 1638
rem_ticks would be 1639, which is 1 greater than dur_ticks/2.

If k_thread_join() was passed with an actual timeout value,
and not K_FOREVER, the blocking thread was not being properly
woken up when the target thread exits. The timeout itself
was never aborted, causing the joining thread to remain
un-scheduled until the timeout expires.
Amend the k_thread_join() test cases to check that the join
completed before the provided timeout period expired.

This commit renames the Kconfig `FLOAT` symbol to `FPU`, since this

toolchain-level floating point support (i.e. this symbol is not
selected when building for an FPU-less platform that supports floating
point operations through the toolchain-provided software floating point

Moreover, given that the symbol that indicates the availability of FPU
is named `CPU_HAS_FPU`, it only makes sense to use "FPU" in the name of
the symbol that enables the FPU.

The test of the absolute timeout feature was a simple whitebox test
that inspected the generated ticks field of different constructors for
identity. But it wasn't simple enough, because it was doing a
ticks->ms->ticks conversion (at compile time, sigh) on the input data,
which is obviously lossy on platforms where ticks are shorter than
milliseconds by non-integral factors.
Fix to do the conversion in just one direction.

This test sets a timer, busy waits for half the duration, and then
checks the remaining time is correct. And it correctly does all its
math in tick precision and aligns to a timer interrupt to eliminate
aliasing due to the tick stride.
But it's waiting using k_busy_wait(), not a timer: "half the duration"
in MICROSECONDS (for k_busy_wait()) is not necessarily representable
as an integer number of TICKS on all platforms. Because k_busy_wait()
always rounds up, we need one extra tick of buffer on those platforms.

These five tests (mbox_api, mheap_api_concept, msgq_api, pipe_api and
queue) all had test cases where they needed a mem_pool allocation to
FAIL. And they are all written to assume the behavior of the original
allocator and not the more general k_heap code, which actually
succeeds in a bunch of these cases.
* Even a very small heap saves enough metadata memory for the very
small minimum block size, and this can be re-used as an allocation.
So you can't assume a small heap is full.
* Calculating the number of blocks based on "num_blocks * max size /
minimum size" and allocating them does not fill the heap, because
the conservative metadata reservation leaves some space left over.
So these have all been modified to "fill" a heap by iteratively
allocating until failure.
Also, this fixes a benign overrun bug in mbox. The test code would
insert a "big" message by reading past the end of the small message
buffer. This didn't fail because it happened to be part of an array
of messages and the other ones defined contained the memory read. But
still.

out of memory in exactly the same way.
Adjust the expectations as needed for the backend. A few test cases
were skipped if they were too specific. Most have been generalized
(for example, iteratively allocating to use up all memory instead of
assuming that it will be empty after N allocations).

k_ticks_t used in timeout computations pervasively 64 bit. This will

upcoming commit.

Add a k_timeout_t type, and use it everywhere that kernel API
functions were accepting a millisecond timeout argument. Instead of
forcing milliseconds everywhere (which are often not integrally
representable as system ticks), do the conversion to ticks at the
point where the timeout is created. This avoids an extra unit
conversion in some application code, and allows us to express the
timeout in units other than milliseconds to achieve greater precision.
The existing K_MSEC() et. al. macros now return initializers for a
k_timeout_t.
The K_NO_WAIT and K_FOREVER constants have now become k_timeout_t
values, which means they cannot be operated on as integers.
Applications which have their own APIs that need to inspect these
vs. user-provided timeouts can now use a K_TIMEOUT_EQ() predicate to
test for equality.
Timer drivers, which receive an integer tick count in ther
z_clock_set_timeout() functions, now use the integer-valued
K_TICKS_FOREVER constant instead of K_FOREVER.
For the initial release, to preserve source compatibility, a
CONFIG_LEGACY_TIMEOUT_API kconfig is provided. When true, the
k_timeout_t will remain a compatible 32 bit value that will work with
any legacy Zephyr application.
Some subsystems present timeout (or timeout-like) values to their own
users as APIs that would re-use the kernel's own constants and
conventions. These will require some minor design work to adapt to
the new scheme (in most cases just using k_timeout_t directly in their
own API), and they have not been changed in this patch, instead
selecting CONFIG_LEGACY_TIMEOUT_API via kconfig. These subsystems
include: CAN Bus, the Microbit display driver, I2S, LoRa modem
drivers, the UART Async API, Video hardware drivers, the console
subsystem, and the network buffer abstraction.
k_sleep() now takes a k_timeout_t argument, with a k_msleep() variant
provided that works identically to the original API.
Most of the changes here are just type/configuration management and
documentation, but there are logic changes in mempool, where a loop
that used a timeout numerically has been reworked using a new
z_timeout_end_calc() predicate. Also in queue.c, a (when POLL was
enabled) a similar loop was needlessly used to try to retry the
k_poll() call after a spurious failure. But k_poll() does not fail
spuriously, so the loop was removed.

Kernel timeouts have always been a 32 bit integer despite the
existence of generation macros, and existing code has been
inconsistent about using them. Upcoming commits are going to make the
timeout arguments opaque, so fix things up to be rigorously correct.
Changes include:
+ Adding a K_TIMEOUT_EQ() macro for code that needs to compare timeout
values for equality (e.g. with K_FOREVER or K_NO_WAIT).
+ Adding a k_msleep() synonym for k_sleep() which can continue to take
integral arguments as k_sleep() moves away to timeout arguments.
+ Pervasively using the K_MSEC(), K_SECONDS(), et. al. macros to
generate timeout arguments.
+ Removing the usage of K_NO_WAIT as the final argument to
K_THREAD_DEFINE(). This is just a count of milliseconds and we need
to use a zero.
This patch include no logic changes and should not affect generated
code at all.

The current nested interrupt test implementation is both buggy and
fundamentally flawed because it does not trigger a higher priority
interrupt from a lower priority interrupt context and relies on the
system timer interrupt, which is not fully governed by the test;
moreover, the current implementation does not properly validate the
test results and can report success if no interrupt is triggered and
serviced at all.
This commit reworks this test to have the following well-defined
and logical procedure:
1. [thread] Trigger IRQ 0 (lower priority)
2. [isr0] Set ISR 0 result token and trigger IRQ 1 (higher priority)
3. [isr1] Set ISR 1 result token and return
4. [isr0] Validate ISR 1 result token and return
5. [thread] Validate ISR 0 result token
The reworked test scenario ensures that the interrupt nesting works
properly and any abnormal conditions are detected (e.g. interrupts not
triggering at all, or ISR 1 not being nested under ISR 0).

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.

The minimum possible mempool block size is either 8 or 16 for 32-bit or
64-bit targets respectively. Defining BYTES_TO_WRITE to 4 and using that
with K_MEM_POOL_DEFINE() won't produce the expected result i.e. only 1
block at any time could be allocated instead of 4.
Yet, the test does run successfully regardless of the block allocation
loop in tpipe_block_put().
It turns out that the pipe buffer is large enough to consume all the
block data synchronously, meaning that the mempool block is freed right
away and available for the next loop iteration. This also means that the
asynchronous delivery mechanism is never exercized.
Fix both issues by defining PIPE_LEN and BYTES_TO_WRITE in terms of
_MPOOL_MINBLK with the expected factor of 4, and adding a new test
using the half-sized pipe where the pipe buffer gets saturated and
mempool memory blocks are actually queued for asynchronous consumption.

The application main() in Zephyr is defined as having a prototype:
void main(void), as expected by the kernel init (bg_thread_main).
So, correct the different samples and tests that were defined
otherwise.

This test has a problem, specifically in the scenario for
test_mem_domain_remove_partitions. A low priority thread (10)
is created which is expected to produce an exception. Then
the following happens:
- The thread indeed crashes and ends up in the custom fatal
error handler, on the stack used for exceptions
- The call to ztest_test_pass() is made
- ztest_test_pass() gives the test_end_signal semaphore
- We then context switch to the ztest main thread which is
higher priority, leaving the thread that crashed context
switched out *on the exception stack*
- More tests are run, and some of them also produce exceptions
- Eventually we do a sleep and the original crashed thread is
swapped in again
- Since several other exceptions have taken place on the
exception stack since then, resuming context results in
an unexpected error, causing the test to fail
Only seems to affect arches that have a dedicated stack for
exceptions, like x86_64. For now, increase the priority of
the child thread so it's cleaned up immediately. Longer-term,
this all needs to be re-thought in the test case to make this
less fragile.

Device initialization may require use of generic services such as
starting up power rails, some of which may be controlled by GPIOs on
an external controller that can't be used until full kernel services
are available. Generic services can check k_is_in_isr() and mediate
their behavior that way, but currently have no way to determine that
the kernel is not available.
Provide a function that indicates whether initialization is still in
pre-kernel stages where no kernel services are available.

Entering irq_offload() on multiple CPUs can cause
difficult to debug/reproduce crashes. Demote irq_offload()
to non-inline (it never needed to be inline anyway) and
wrap the arch call in a semaphore.
Some tests which were unnecessarily killing threads
have been fixed; these threads exit by themselves anyway
and we won't leave the semaphore dangling.
The definition of z_arch_irq_offload() moved to
arch_interface.h as it only gets called by kernel C code.

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.

The k_thread_state_str is a new function added into

- The two different structures for page directory entries were

On 64-bit targets, the minimum possible mempool block size is not 8
but 16. With a max block size of 32, the mempool allocator cannot
split it into 4 sub-blocks, reducing the available memory allocations
to that original 32-byte block only.
To get the same allocation patterns and test behavior whether it is
built for a 32-bit or 64-bit architecture, let's define BLK_SIZE_MIN
and BLK_SIZE_MAX in terms of _MPOOL_MINBLK instead of literal values.
