* @brief This test case collection provides validation test cases for SMP-only
* requirements of the @ref RTEMSAPIClassicScheduler.
*
* This test case performs the following actions:
*
* - Call rtems_scheduler_get_processor() on all online processors and check
* the returned value.
*
* - Call rtems_scheduler_get_processor_maximum() and check the returned value.
*
* - Check that the returned value is greater than or equal to one.
*
* - Check that the returned value is less than or equal to
* rtems_configuration_get_maximum_processors().
*
* - Call rtems_scheduler_ident() for each configured scheduler.
*
* - Check that the object index of scheduler A has the expected value.
*
* - Check that the object index of scheduler B has the expected value.
*
* - Check that the object index of scheduler C has the expected value.
*
* - Check that the object index of scheduler D has the expected value.
*
* - Check that processor 0 has scheduler A assigned.
*
* - Check that processor 1 has scheduler B assigned.
*
* - Check that scheduler B has the maximum priority of the EDF SMP
* scheduler.
*
* - Check that processor 2 has scheduler C assigned if it is present.
*
* - Check that processor 3 has scheduler C assigned if it is present.
