This suite was fairly messy and very unstable on how it re-used
kernel objects.
* Unnecessary ztest_test_pass() or self-aborts removed
* k_thread_join() now used to wait for child thread completion,
instead of a strange use of a semaphore which was effectively
a 10ms sleep
* Barriers simplified
* the number of thread objects in kobject.c is now drastically reduced
* test case function names are now descriptive and made static if
only used in local scope in kobject.c
* SMP no longer disabled

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
symbol only indicates that the hardware Floating Point Unit (FPU) is
used and does not imply and/or indicate the general availability of
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
library).
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.

The k_heap backend is now the default for mem_pool, so duplicate these
tests across that config so we continue to have coverage for the older
code.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The original k_mem_pool tests were a mix of code that tests routine
allocator behavior, the synchronization layer above that, and a
significant amount of code that made low-level assumptions about the
specific memory layout of the original allocator, which doesn't run
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).

Add support for "absolute" timeouts, which are expressed relative to
system uptime instead of deltas from current time. These allow for
more race-resistant code to be written by allowing application code to
do a single timeout computation, once, and then reuse the timeout
value even if the thread wakes up and needs to suspend again later.

Add a CONFIG_TIMEOUT_64BIT kconfig that, when selected, makes the
k_ticks_t used in timeout computations pervasively 64 bit. This will
allow much longer timeouts and much faster (i.e. more precise) tick
rates. It also enables the use of absolute (not delta) timeouts in an
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.

This commit disables the nested interrupt test for the RISC-V platform,
as interrupt nesting is not supported on the current RISV-C

that in the codebase (see #23593).

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).

Using find_package to locate Zephyr.
Old behavior was to use $ENV{ZEPHYR_BASE} for inclusion of boiler plate
code.
Whenever an automatic run of CMake happend by the build system / IDE
then it was required that ZEPHYR_BASE was defined.
Using ZEPHYR_BASE only to locate the Zephyr package allows CMake to
cache the base variable and thus allowing subsequent invocation even
if ZEPHYR_BASE is not set in the environment.
It also removes the risk of strange build results if a user switchs
between different Zephyr based project folders and forgetting to reset
ZEPHYR_BASE before running ninja / make.
