Use a busy loop with non-blocking Semaphore::wait(0) calls instead of a
single Semaphore::wait(osWaitForever) to improve time measurement
accuracy. Looping in Semaphore::wait(0) prevents the board from entering
sleep or deepsleep modes while waiting for the semaphore. By skipping
the overhead wakeup time, we get more accurate timings.
It will be too hard to try to intercept and continue from a trapped
error once error functions are marked [[noreturn]], so make the error
return tests conditional on error trapping being disabled.
Static Thread methods and signal methods have been deprecated. Remove
all references in the main code, and most of the tests. Some tests of
the deprecated APIs themselves remain.
Remove the double free RTOS tests since this was never defined
behavior of CMSIS-RTOS. This allows testing to pass.
The RTX commit which caused this test to start failing is:
c3b123ef4256f65537e2597af475fc20ec9a383e
RTX5: updated MemoryPoolFree (removed count check) [SDCMSIS-801]
Note - Double freeing an element from a memory pool was never safe.
The error return value when double freeing was misleading since memory
corruption may still be occurring in that case. For more information
on this see SDCMSIS-801.
The thread stack size was restricted due to some boards have really limited RAM sizes,
and out of heap memory on multiple threads tests.
The side effect was on the debug profile build, the tests will get stack overflow.
We need the build the test with debug profile in order to do the code coverage analysis.
So increased the thread stack size on FastModel targets.
FastModels targets are simulator running on the x86 hosts.
As the nature of non-RealTime x86 OS and FastModels, timing accuracy is not guaranteed
So skipping the time drifting tests on FastModel targets
When the define LPTICKER_DELAY_TICKS is set deep sleep can be randomly
disallowed when using the low power ticker. This is because a Timer
object, which locks deep sleep, is used to protect from back-to-back
writes to lp tickers which can't support that. This causes tests which
assert that deep sleep is allowed to intermittently fail.
To fix this intermittent failure this patch adds the function
sleep_manager_can_deep_sleep_test_check() which checks if deep sleep
is allowed over a duration. It updates all the tests to use
sleep_manager_can_deep_sleep_test_check() rather
than sleep_manager_can_deep_sleep() so the tests work even if deep
sleep is spuriously blocked.
Since target specific ticker drivers are not ready also features which uses ticker in upper layers may not work correctly and tests for these features.
We need to disable also failing higher level ticker related tests (by adding check if DEVICE_USTICKER symbol is available and raise #error [NOT_SUPPORTED] if not).
Update the SysTimer test to match the updated API. Changes are:
- increment_tick() renamed to _increment_tick() and explicitly
synchronized
-update_tick() replaced with resume() and a call to suspend() was added
before this
In pararell threads of "thread" test is a simple thread, but it seems that there is a difference in the stack used between Cortex-A and Cortex-M.
As a result of check, in Cortex-A, program aborts because of the lack of stack when PARALLEL_THREAD_STACK_SIZE is 384, workes properly when PARALLEL_THREAD_STACK_SIZE is 512 at least.
"malloc" test is used a simple thread that executes only malloc and free, but it seems that there is a difference in the stack used between Cortex-A and Cortex-M.
As a result of check, in Cortex-A, program aborts because of the lack of stack when THREAD_STACK_SIZE is 256, workes properly when THREAD_STACK_SIZE is 512 at least. Since it seems that the definition processing of "DEFAULT_STACK_SIZE" was gone from Mbed OS by updating CMSIS5/RTX5, I setted 512 directly for Cortex-A.
