- * Ring
- * ====
- *
- * #. Basic tests: done on one core:
- *
- * - Using single producer/single consumer functions:
- *
- * - Enqueue one object, two objects, MAX_BULK objects
- * - Dequeue one object, two objects, MAX_BULK objects
- * - Check that dequeued pointers are correct
- *
- * - Using multi producers/multi consumers functions:
- *
- * - Enqueue one object, two objects, MAX_BULK objects
- * - Dequeue one object, two objects, MAX_BULK objects
- * - Check that dequeued pointers are correct
- *
- * - Test watermark and default bulk enqueue/dequeue:
- *
- * - Set watermark
- * - Set default bulk value
- * - Enqueue objects, check that -EDQUOT is returned when
- * watermark is exceeded
- * - Check that dequeued pointers are correct
- *
- * #. Check live watermark change
- *
- * - Start a loop on another lcore that will enqueue and dequeue
- * objects in a ring. It will monitor the value of watermark.
- * - At the same time, change the watermark on the master lcore.
- * - The slave lcore will check that watermark changes from 16 to 32.
- *
- * #. Performance tests.
- *
- * Tests done in test_ring_perf.c
