The first word is used as a pointer, meaning it is 64 bits on 64-bit
systems. To reserve it, it has to be either a pointer, a long, or an
intptr_t. Not an int nor an u32_t.

Unfortunately this seems to have introduced spurious failures on (at
least) qemu_x86 and qemu_xtensa.
The change limits the timeslice tolerance to +/- 1ms, which isn't
necessarily correct when the tick rate is less than 1ms (though it
will probably work on deterministic hardware as long as the system is
hitting the target at exactly the right tick), and isn't even
theoretically achievable on emulation environments where timing
granularity is limited by the host scheduling quantum.
What this needs to do is check the deadline is off by at most one
tick, and trust the platform integration to have set the tick rate
appropriately.
(I do worry that the earlier version of the test was trying to set the
limit at half the TICKLESS_IDLE_THRESHOLD, though -- that seems weird,
and hints that maybe the test is trying to do something more
elaborate?)

YAML document separators are needed e.g. when doing
$ cat doc1.yaml doc2.yaml | <parser>
For the bindings, we never parse concatenated documents. Assume we don't
for any other .yaml files either.
Having document separators in e.g. base.yaml makes !include a bit
confusing, since the !included files are merged and not separate
documents (the merging is done in Python code though, so it makes no
difference for behavior).
The replacement was done with
$ git ls-files '*.yaml' | \
xargs sed -i -e '${/\s*\.\.\.\s*/d;}' -e 's/^\s*---\s*$//'
First pattern removes ... at the end of files, second pattern clears a
line with a lone --- on it.
Some redundant blank lines at the end of files were cleared with
$ git ls-files '*.yaml' | xargs sed -i '${/^\s*$/d}'
This is more about making sure people can understand why every part of a
binding is there than about removing some text.

On 64-bit systems the most notable difference is due to longs and

The k_stack data type cannot be u32_t on a 64-bit system as it is
often used to store pointers. Let's define a dedicated type for stack
data values, namely stack_data_t, which can be adjusted accordingly.
For now it is defined to uintptr_t which is the integer type large
enough to hold a pointer, meaning it is equivalent to u32_t on 32-bit
systems and u64_t on 64-bit systems.

Using void pointers as universal arguments is widely used. However, when
compiling a 64-bit target, the compiler doesn't like when an int is
converted to a pointer and vice versa despite the presence of a cast.
This is due to a width mismatch between ints (32 bits) and pointers
(64 bits). The trick is to cast to a widening integer type such as
intptr_t and then cast to
void*.
When appropriate, the INT_TO_POINTER macro is used instead of this
double cast to make things clearer. The converse with POINTER_TO_INT
is also done which also serves as good code annotations.
While at it, remove unneeded casts to specific pointer types from void*
in the vicinity, and move to typed variable upon function entry to make
the code cleaner.

The test_timer_periodicity waits for first timer expiration
in order to extract timer firing time. The wait is performed
using k_timer_status_sync() API call, which blocks thread
until timer expiration. However if the timer expired before
call the this function, it will return immediately, triggering
test failure.
This commit adds the second call to the k_timer_status_sync()
to ensure that the following part of the test will be executed
as soon as possible after timer expiration.

Contrary to the comment in code, this test is NOT, in fact, compiled
with a traditional ticked kernel. Spinning won't work reliably
because interrupts won't necessarily be delivered when you expect.

Doing it right (using a k_timer in this case) is actually less code

In the wake of moving the internal API header arm_core_mpu_dev.h
into arch/arm/cortex_m/mpu, we need to explicitly declare the
arm_core_mpu_disable() function in the userspace test. Note that
arm_core_mpu_disable() (as any other function in this internal
API) is not supposed to be called directly by kernel/application
functions; an exception is allowed in this test suite, so we are

- Delete CONFIG_TEST_USERSPACE=n no-ops because it's the default
since commit 7b1ee5cf13
- Some tests have a "userspace" tag pretending to TEST_USERSPACE but
don't and vice versa: fix missing or spurious "userspace" tags in
testcase.yaml files.
Tests have a _spurious_ "userspace" tag when they PASS this command
cause none should pass:
./scripts/sanitycheck --tag=userspace -p qemu_x86 \
--extra-args=CONFIG_TEST_USERSPACE=n \
--extra-args=CONFIG_USERSPACE=n | tee userspace.log
All tests run by this command must either fail to build or fail to run
with some userspace related error. Shortcut to look at all test
failures:
zephyr_failure_logs() {
awk '/see.*log/ {print $2}' "$@"
}
Tests _missing_ "userspace" tag FAIL to either build or to run with some
userspace related error when running this:
./scripts/sanitycheck --exclude=userspace -p qemu_x86 \
--extra-args=CONFIG_TEST_USERSPACE=n \
--extra-args=CONFIG_USERSPACE=n | tee excludeuserspace.log
Note the detection methods above are not 100% perfect because some
flexible tests like tests/kernel/queue/src/main.c evade them with #ifdef
CONFIG_USERSPACE smarts. Considering they never break, it is purely the
test author's decision to include or not such flexible tests in the
"userspace" subset.
