This is the NuttX _qualification_ suite. It attempts to exercise a broad set of
|
|
|
|
|
|
OS functionality. Its coverage is not very extensive as of this writing, but it
|
|
|
|
|
|
is used to qualify each NuttX release.
|
|
|
|
|
|
|
|
|
|
|
|
The behavior of the ``ostest`` can be modified with the following settings in the
|
|
|
|
|
|
``boards/<arch>/<chip>/<board>/configs/<config>/defconfig`` file:
|
|
|
|
|
|
|
|
|
|
|
|
- ``CONFIG_NSH_BUILTIN_APPS`` – Build the OS test example as an NSH built-in
|
|
|
|
|
|
application.
|
|
|
|
|
|
- ``CONFIG_TESTING_OSTEST_LOOPS`` – Used to control the number of executions of
|
|
|
|
|
|
the test. If undefined, the test executes one time. If defined to be zero,
|
|
|
|
|
|
the test runs forever.
|
|
|
|
|
|
|
|
|
|
|
|
- ``CONFIG_TESTING_OSTEST_STACKSIZE`` – Used to create the ostest task. Default is
|
|
|
|
|
|
``8192``.
|
|
|
|
|
|
- ``CONFIG_TESTING_OSTEST_NBARRIER_THREADS`` – Specifies the number of threads to
|
|
|
|
|
|
create in the barrier test. The default is 8 but a smaller number may be
|
|
|
|
|
|
needed on systems without sufficient memory to start so many threads.
|
|
|
|
|
|
|
|
|
|
|
|
- ``CONFIG_TESTING_OSTEST_RR_RANGE`` – During round-robin scheduling test two
|
|
|
|
|
|
threads are created. Each of the threads searches for prime numbers in the
|
|
|
|
|
|
configurable range, doing that configurable number of times. This value
|
|
|
|
|
|
specifies the end of search range and together with number of runs allows to
|
|
|
|
|
|
configure the length of this test – it should last at least a few tens of
|
|
|
|
|
|
seconds. Allowed values ``[1; 32767]``, default ``10000``.
|
|
|
|
|
|
|
|
|
|
|
|
- ``CONFIG_TESTING_OSTEST_RR_RUNS`` – During round-robin scheduling test two
|
|
|
|
|
|
threads are created. Each of the threads searches for prime numbers in the
|
|
|
|
|
|
configurable range, doing that configurable number of times.
