In 972a4d9f6f
the test was relaxed to allow a possible parallel thread
waking the CPU during the idle timeout checks.
How this was done though, a system timer driver
which wakes the kernel spuriously a bit before the
correct deadline would not be detected, even
though it should.
Let's fix this, ensuring the timer has been
called when we check the wake time in inside the
expected range.

This test assumes that nothing will wake the CPU apart from
the timer set by the test.
But that is not necessarily the case.
Some other platform thread started at boot
may be waking the CPU every now and then.
Let's allow for some spurious wakes while we are testing k_cpu_idle,
while at the same time ensuring we are not just busy waiting
all the way.

Because it was exclusively used by the "common" RISC-V privileged code
to build CPU idle routines that are now handled by arch level code.
Also, all platforms defaulted to "y", making it pointless in practice.

This test assumes nothing else is running in the background
but when the logger is on, this board will by default
start the RTC sync mechanism, which will awake the CPU
every now and then.
Let's disable this mechanism to avoid disturbing the test.

The kernel/context test_timer_interrupts() test has a loop calibration
phase to estimate the number of loops needed for 1 system tick.
By initializing this calibration to 1 instead of 0, we can avoid an
edge condition where the calibration phase indicates 0 loops are
required (a case that could happen when running on a slow simulator).

In test_busy_wait and test_k_sleep test cases of
tests/kernel/context test we measure not only execution time of the
primitives itself (k_busy_wait and k_msleep respectively) but also
the overall test thread execution time.
The issue here is that we do printing in test threads which
means that we do printing in time-critical sections. That breaks
test if we do printing via some device which isn't fast enough.
Fix that by removing print from time-critical section

Signed-off-by: Fabio Baltieri <fabiobaltieri@google.com>
This test was written to idle for exactly 1ms and wake up with zero
error, which is just too tight for some platforms (and worked on
emulators where the tick rate is 10x coarser only because 0 == 0!).
And it's not clear that it's testing anything we promise in
documentation, regardless. Early wakeups are not an error and
absolutely not disallowed, yet the test is treating the wakeup like a
sleep.
Clean it up a bit and relax the tolerance to what we can compute
reliably: do all the math in ticks, idle for 10ms (i.e. longer than a
host quantum for emulators), and allow 1 tick of slop on either side to
permit slightly early wakeups while still verifying that "yes, the idle
did idle".

This test has gotten out of control. It has a giant #if cascade
enumerating every timer driver in the Zephyr tree and extracting its

expose that interrupt in its platform headers or some other API.

This commit adds an additional test case for several kernel test suites
to ensure that the linker script generator is working correctly for a
subset of the Zephyr test suites.
The ensures that the basic functionality of the linker script generator
is working while still keep the performance impact on CI at a minimal
level.
Using the kernel tests is a trade-off between testing coverage of the
linker script generator and the time it takes to complete CI.
The kernel tests is considered to have the broadest coverage of various
features important for the generated linker script.

The main reason for increasing CMake version is better toolchain

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.

For a while now, we've had two APIC drivers. The older was preserved
initially as the new (much smaller, "new style") code didn't have

remove it.
Note that this migrates the one board using this driver (acrn) to
CONFIG_APIC_TIMER instead.
