This patch adds a way to simplify using an external tool to measure
timer behaviour on Zephyr. It modifies the timer behaviour
jitter_drift.c tests to toggle a GPIO pin (defined via a new DTS
compatible, "test-kernel-timer-behavior-external") that can be connected
to an external tool, such as a logic analyzer, to measure timer
behaviour.
This GPIO pin toggle is behind a new CONFIG_TIMER_EXTERNAL_TEST Kconfig.
A new pytest test is added so that it can collect the statistics from
the external tool and assert some measurements. To collect statistics
from the external tool, one needs to provide a Python module which
provides a `run(seconds, config)` method, that will perform the test and
return the statistics. Check the README file for more information about
this interface.
Finally, this on twister, this new test is behind a new fixture,
"gpio-timerout".

This is the final step in making the `zephyr,memory-attr` property
actually useful.
The problem with the current implementation is that `zephyr,memory-attr`
is an enum type, this is making very difficult to use that to actually
describe the memory capabilities. The solution proposed in this PR is to
use the `zephyr,memory-attr` property as an OR-ed bitmask of memory
attributes.
With the change proposed in this PR it is possible in the DeviceTree to
mark the memory regions with a bitmask of attributes by using the
`zephyr,memory-attr` property. This property and the related memory
region can then be retrieved at run-time by leveraging a provided helper
library or the usual DT helpers.
The set of general attributes that can be specified in the property are
defined and explained in
`include/zephyr/dt-bindings/memory-attr/memory-attr.h` (the list can be
extended when needed).
For example, to mark a memory region in the DeviceTree as volatile,
non-cacheable, out-of-order:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_VOLATILE |
DT_MEM_NON_CACHEABLE |
DT_MEM_OOO )>;
};
The `zephyr,memory-attr` property can also be used to set
architecture-specific custom attributes that can be interpreted at run
time. This is leveraged, among other things, to create MPU regions out
of DeviceTree defined memory regions on ARM, for example:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-region = "NOCACHE_REGION";
zephyr,memory-attr = <( DT_ARM_MPU(ATTR_MPU_RAM_NOCACHE) )>;
};
See `include/zephyr/dt-bindings/memory-attr/memory-attr-mpu.h` to see
how an architecture can define its own special memory attributes (in
this case ARM MPU).
The property can also be used to set custom software-specific
attributes. For example we can think of marking a memory region as
available to be used for memory allocation (not yet implemented):
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_NON_CACHEABLE |
DT_MEM_SW_ALLOCATABLE )>;
};
Or maybe we can leverage the property to specify some alignment
requirements for the region:
mem: memory@10000000 {
compatible = "mmio-sram";
reg = <0x10000000 0x1000>;
zephyr,memory-attr = <( DT_MEM_CACHEABLE |
DT_MEM_SW_ALIGN(32) )>;
};
The conventional and recommended way to deal and manage with memory
regions marked with attributes is by using the provided `mem-attr`
helper library by enabling `CONFIG_MEM_ATTR` (or by using the usual DT
helpers).
When this option is enabled the list of memory regions and their
attributes are compiled in a user-accessible array and a set of
functions is made available that can be used to query, probe and act on
regions and attributes, see `include/zephyr/mem_mgmt/mem_attr.h`
Note that the `zephyr,memory-attr` property is only a descriptive
property of the capabilities of the associated memory region, but it
does not result in any actual setting for the memory to be set. The
user, code or subsystem willing to use this information to do some work
(for example creating an MPU region out of the property) must use either
the provided `mem-attr` library or the usual DeviceTree helpers to
perform the required work / setting.

The default tick rate for the nRF RTC timer is 32768 Hz, so one tick
is ~30 us. This turns out to be too little for the following loop
executed in user mode on the Network core in nRF5340:
```
do {
t0 = k_uptime_ticks();
rem_ticks = k_timer_remaining_ticks(&remain_timer);
t1 = k_uptime_ticks();
} while (t0 != t1);
```
The time between the two calls to `k_uptime_tick()` is there always
above 30 us, so the loop never ends.
This patch decreases the tick rate for all nRF platforms because on
other nRf SoCs the time mentioned above is also close to 30 us and
apparently changes in code completely unrelated to this test affect
execution time of system calls in the above loop - the test started
to fail after commit 0014dd05f0 that
changes fdtable was merged and if `fdtable.c` is for example just
temporarily excluded from the build, the test passes.
The root cause of the problem seems to be related to user space
handling and this should to be investigated further. This patch

If the timer driver only implements sys_clock_cycle_get_32() (meaning
CONFIG_TIMER_HAS_64BIT_CYCLE_COUNTER=n) and the hardware clock is high
enough then the reported cycle count may wrap an uint32_t during the
test. This makes validating the total test duration pointless as it
cannot be measured. Just print a warning instead of failing the test
in that case.

As both C and C++ standards require applications running under an OS to
return 'int', adapt that for Zephyr to align with those standard. This also
eliminates errors when building with clang when not using -ffreestanding,
and reduces the need for compiler flags to silence warnings for both clang
and gcc.
Most of these changes were automated using coccinelle with the following
script:
@@

- void
+ int
main(...) {
...
- return;

}
Approximately 40 files had to be edited by hand as coccinelle was unable to
fix them.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

Nordic targets use 24-bit RTC peripheral for system clock. Nordic system
clock timeout implementation relies on RTC CC (capture compare) when
the timeout is in future. Nordic system clock driver allows setting
alarm only to 3 or more counts from current counter value due to silicon
limitation (to ensure that CC event triggers before counter overflow).
RTC CC limitation does not have much impact on normal applications where
there is no need to schedule such short timeouts, but is problematic in
a timer test that expects being able to repeatedly schedule timeouts on
subsequent ticks.
Reduce system tick rate to 8192 on nRF targets to allow setting CC to
the very next tick. With system tick rate being 4 times less than the
hardware tick rate, it is always possible to schedule timeout to happen
in the next tick because ticks are 4 counts apart, i.e. current timer
value + 3 never runs past the next tick.

SMP tests `inc_concurrency` and `smp_switch_torture` use a 'stressing'
approach to verify their results: run something for some time (or some
number of repetitions). However, in some environments, current 'stress'
levels can be quite high, making tests take a long time - environments
like emulators/simulators.
This patch adds a Kconfig that allows one to define a percentage factor
to the 'stress' (time or repetitions) used by these tests.

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.

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.

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.

I spent a couple of hours attempting to track this down and found that it

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.
