Don't sample the first entry outside the timer as this is a different
code path which produces a different offset from the clock tick.
Use sys_clock_hw_cycles_per_sec() to be compatible with systems that
read their hardware clock frequency at run time.
Perform cycle difference computations with uint64_t. If ever the
magnitude of the absolute clock cycle values is greater than 52 bits
then the cast to a double will actually lose accuracy.

An assertion statement was a bit too strict. Period drift may come about
not only from kernel ticks being large but also from time conversion being

For some kernel tests, faults and exceptions are expected.
They are caught and the test would continue if the reasons
for faults are as expected. However, when the unexpected
reasons are encountered, the code simply prints a message
and calls k_fatal_halt(). When running under twister,
these messages are not the expected failed messages so
twister will spin till timeout although the execution
has already been halted. This adds another printk() before
halt to signal twister that the test has failed and bails
early.

...test_inherit_resource_pool. This waits for the newly created
threads to finish before moving on to the next test. This fixes

qemu_x86 seems to take an extra instruction after the sti instruction
(irq_unlock) happens before it posts the interrupts. This can issues
if the instruction after the sti ends up reading the state that is
suppose to be updated by the ISR handler.
We see this behavior when building with LLVM. To workaround this issue
we add an arch_nop() to provide an extra instruction to allow the
interrupts to post.
Opened zephyrproject-rtos/sdk-ng#629 to track qemu issue.

LLVM doesn't support SSE + 387 math. As such if SSE is enabled we
have to utilize SSE floating point. To utilize 387 math, SSE has
to be disabled.
Update the floating point related tests to introduce 387 only variants
that will build on both GCC & LLVM based tools. Than we exclude llvm
based (llvm, oneApi) toolchains from the CONFIG_X86_SSE_FP_MATH=n and
CONFIG_X86_SSE=y test variants.

Print the "perfect" reference period for easier evaluation.
Suggest a remedy to the missed ticks problem.
Still, that wasn't satisfactory. Implemented a count of missed ticks
to get to the bottom of this issue. Found that missed ticks always came
to a perfect count of 40.
Incidentally, the busy loop prints a line every 250 ms and the test spans
10 seconds. There are no such coincidences.
Turns out that CONFIG_PRINTK_SYNC was set by default. This disables IRQs
for the serial output duration, which can be quite long at 115200 bauds.
Given a 60-ish character line length, this represents more than 5 ms of
no IRQ servicing during a timer latency measurement test which is bad.
So make sure CONFIG_PRINTK_SYNC=n for proper statistics.

This test has trouble on qemu_x86_tiny and randomly generates a Double
Fault error. I couldn't get it to reliably run with picolibc as a Double
Fault usually occured before the test completed.
I spent a couple of hours attempting to track this down and found that it
happens when code pages for the main thread get unmapped because the
qemu_x86_tiny intentionally offers very few available PTEs.
Work around this by just using the minimal libc for this test.

The rootcause if that we doesn't proper cleanup resources after
test_fatal_on_smp test case. So child thread we start test_fatal_on_smp
may continue running for some time after the test_fatal_on_smp
test case is finished.
As in the next test case (test_get_cpu) we use same thead structures
again to create new child thread we may actually rewrite some data of
thread which is still running (or vise versa).
As we trigger the crash in test_fatal_on_smp we can't simply join
child thread in the end of test case (as we never get here). We can't
simply use join child thread before we initiate crash in test_fatal_on_smp
either as we don't want to introduce reschedule point here which may break
the test logic.
So, to fix that, we'll just do k_busy_wait in test_fatal_on_smp
thread after we start child thread to wait for thread trigger
exception and being terminated.
To verify that we also assert that child thread is dead by the
time when we stop busy waiting.

Signed-off-by: Piotr Kosycarz <piotr.kosycarz@nordicsemi.no>
The spin loop to ensure time goes past the timeout is done in terms
of the core clock, while the spin lock is timed on the system clock.
This difference is exasperated on systems where the core clock is much
faster than the system clock and the test failed. Add a significant
multiplier so the test works even when the system clock is much slower.
