+ *
+ * @ingroup TestsuitesValidationSmpOnly0
+ *
+ * @brief Tests some @ref RTEMSAPIClassicIntr directives.
+ *
+ * This test case performs the following actions:
+ *
+ * - Validate the interrupt lock directives.
+ *
+ *   - Check that RTEMS_INTERRUPT_LOCK_REFERENCE() expanded to a lock reference
+ *     definition.  Check that the lock is available after static
+ *     initialization.
+ *
+ *   - Check that the lock is available after initialization.
+ *
+ *   - Check that maskable interrupts are disabled before the call to
+ *     rtems_interrupt_lock_interrupt_disable() and disabled afterwards.
+ *
+ *   - Check that the maskable interrupt status is not changed by the
+ *     rtems_interrupt_lock_acquire_isr() call.  Check that the lock is no
+ *     longer available.
+ *
+ *   - Check that the maskable interrupt status is restored by the call to
+ *     rtems_interrupt_lock_release() according to the ``_lock_context``
+ *     parameter.  Check that the lock is available afterwards.
+ *
+ *   - Check that the maskable interrupt status is not changed by the
+ *     rtems_interrupt_lock_destroy() call.
+ *
+ *   - Initialize the lock using rtems_interrupt_lock_initialize().  Check that
+ *     the lock is available after initialization.
+ *
+ *   - Check that maskable interrupts are disabled before the call to
+ *     rtems_interrupt_lock_acquire() and disabled afterwards.  Check that the
+ *     lock is no longer available.
+ *
+ *   - Check that the maskable interrupt status is restored by the call to
+ *     rtems_interrupt_lock_release() according to the ``_lock_context``
+ *     parameter.  Check that the lock is available afterwards.
+ *
+ *   - Check that the maskable interrupt status is not changed by the
+ *     rtems_interrupt_lock_destroy() call.
