If the idle code was detecting that it needed to sleep for less than
CONFIG_SYS_TICKLESS_IDLE_THRESH, then it would never call
z_clock_set_timeout() at all, which means that the system would never
wake up unless it already had a timeout scheduled! Apparently we
lacked a test case to detect this condition.
Honestly this seems like a crazy feature to me. There's no benefit in
delivering needless tick announcements. If the system has the
capacity to enter deeper sleep for long timeouts, that's already
exposed via the PM APIs, the timer subsystem needn't be involved.
But... we actually have a test (tickless_concept) that looks at this,
so support it for now and consider deprecation later.

The system tick count is a 64 bit quantity that gets updated from
interrupt context, meaning that it's dangerously non-atomic and has to
be locked. The core kernel clock code did this right.
But the value was also exposed to the rest of the universe as a global
variable, and virtually nothing else was doing this correctly. Even
in the timer ISRs themselves, the interrupts may be themselves
preempted (most of our architectures support nested interrupts) by
code that wants to set timeouts and inspect system uptime.
Define a z_tick_{get,set}() API, eliminate the old variable, and make
sure everyone uses the right mechanism.

This was another "global variable" API. Give it function syntax too.
Also add a warning, because on nRF devices (at least) the cycle clock
runs in kHz and is too slow to give a precise answer here.

This just got turned into a function from a "variable" API, but
post-the-most-recent-patch it turns out to be degenerate anyway.
Everyone everywhere should always have been using the kconfig variable
directly, and it was only a weirdness in the tickless API that made it
confusing. Fix.
Signed-off-by: Andy Ross <andrew.j.ross@intel.com>
The existing API defined sys_clock_{hw_cycles,ticks}_per_sec as simple
"variables" to be shared, except that they were only real storage in
certain modes (the HPET driver, basically) and everywhere else they
were a build constant.
Properly, these should be an API defined by the timer driver (who
controls those rates) and consumed by the clock subsystem. So give
them function syntax as a stepping stone to get there.
Note that this also removes the deprecated variable
_sys_clock_us_per_tick rather than give it the same treatment.

Add default dts configuration for CI tests in case

dts configuration for LIS2MDL
Signed-off-by: Mario Tesi <mario.tesi@st.com>
Added support to LIS2MDL Magnetometer sensor provided
with following features:
- I2C interface
- Mag data
- Temperature data
- ODR configurable by config or at runtime
- Trigger mode selectable by menuconfig
- IRQ pin configurable (by dts or Kconfig)
- Hard Iron offset setting at runtime
- Include yaml file
Tested on ST MEMS IKS01A2 + NUCLEO STM32F411RE board.
LIS2MDL connected to I2C master interface (SPI 3 wire not
supported yet).
Test run with all ODR {10, 20, 50, 100} Hz in poll and
trigger mode.
GPIO IRQ dts configuration has been tested by adding
to boards/arm/nucleo_f411re/nucleo_f411re.dts file
this patch:
&i2c1 {
status = "ok";
clock-frequency = <I2C_BITRATE_FAST>;

+ reg = <0x1e>;
+ irq-gpios = <&gpioa 4 0>;
+ label = "LIS2MDL";
+ status = "ok";
+ };
};
and adding boards/arm/nucleo_f411re/dts.fixup with following
content:
ST_STM32_I2C_V1_40005400_ST_LIS2MDL_MAGN_1E_LABEL

The $srctree environment variable gives the path relative to which
'(o)source' statements work (the current directory is used if $srctree
is unset). It is set to $ZEPHYR_BASE in cmake/kconfig.cmake, so there's
no need to qualify the source of Kconfig.zephyr in sample Kconfig files
(or in external projects).
All 'source's in Zephyr assume that the Zephyr root directory is used as
the srctree as well, and would break otherwise.
Remove the $(ZEPHYR_BASE)s to make it clearer that all 'source'
statements work relative to the Zephyr root. There was some user
confusion on IRC.
Also explain how things work in the documentation.

This commit updates the mem_domain_apis_test sample and the
mem_protect test, so they can compile and execute in ARMv8-M
platforms, which do not support the P_RW_U_RO access permissions
combination (privileged read/write, unprivileged read-only). The
modification consists of, simply, selecting a different access
permission (P_RO_U_RO) when building for ARMv8-M MPUs with the
unmodified ARM MPU architecture.
