| Title: LIFO APIs |
| |
| Description: |
| |
| This test verifies that the nanokernel LIFO APIs operate as expected. |
| |
| --------------------------------------------------------------------------- |
| |
| Building and Running Project: |
| |
| This nanokernel project outputs to the console. It can be built and executed |
| on QEMU as follows: |
| |
| make qemu |
| |
| --------------------------------------------------------------------------- |
| |
| Troubleshooting: |
| |
| Problems caused by out-dated project information can be addressed by |
| issuing one of the following commands then rebuilding the project: |
| |
| make clean # discard results of previous builds |
| # but keep existing configuration info |
| or |
| make pristine # discard results of previous builds |
| # and restore pre-defined configuration info |
| |

| Sample Output: |
| |
| tc_start() - Test Nanokernel LIFO |
| Nano objects initialized |
| Fiber waiting on an empty LIFO |
| Task waiting on an empty LIFO |
| Fiber to get LIFO items without waiting |
| Task to get LIFO items without waiting |
| ISR to get LIFO items without waiting |
| First pass |
| multiple-waiter fiber 0 receiving item... |
| multiple-waiter fiber 1 receiving item... |
| multiple-waiter fiber 2 receiving item... |
| multiple-waiter fiber 0 got correct item, giving semaphore |
| multiple-waiter fiber 1 got correct item, giving semaphore |
| multiple-waiter fiber 2 got correct item, giving semaphore |
| Task took multi-waiter reply semaphore 3 times, as expected. |
| Second pass |
| multiple-waiter fiber 0 receiving item... |
| multiple-waiter fiber 0 got correct item, giving semaphore |
| multiple-waiter fiber 1 receiving item... |
| multiple-waiter fiber 2 receiving item... |
| multiple-waiter fiber 1 got correct item, giving semaphore |
| multiple-waiter fiber 2 got correct item, giving semaphore |
| Task took multi-waiter reply semaphore 3 times, as expected. |
| test nano_task_lifo_get() with timeout > 0 |
| nano_task_lifo_get() timed out as expected |
| nano_task_lifo_get() got lifo in time, as expected |
| testing timeouts of 5 fibers on same lifo |
| got fiber (q order: 2, t/o: 10, lifo 20005ff0) as expected |
| got fiber (q order: 3, t/o: 15, lifo 20005ff0) as expected |
| got fiber (q order: 0, t/o: 20, lifo 20005ff0) as expected |
| got fiber (q order: 4, t/o: 25, lifo 20005ff0) as expected |
| got fiber (q order: 1, t/o: 30, lifo 20005ff0) as expected |
| testing timeouts of 9 fibers on different lifos |
| got fiber (q order: 0, t/o: 10, lifo 20005ffc) as expected |
| got fiber (q order: 5, t/o: 15, lifo 20005ff0) as expected |
| got fiber (q order: 7, t/o: 20, lifo 20005ff0) as expected |
| got fiber (q order: 1, t/o: 25, lifo 20005ff0) as expected |
| got fiber (q order: 8, t/o: 30, lifo 20005ffc) as expected |
| got fiber (q order: 2, t/o: 35, lifo 20005ff0) as expected |
| got fiber (q order: 6, t/o: 40, lifo 20005ff0) as expected |
| got fiber (q order: 4, t/o: 45, lifo 20005ffc) as expected |
| got fiber (q order: 3, t/o: 50, lifo 20005ffc) as expected |
| testing 5 fibers timing out, but obtaining the data in time |
| (except the last one, which times out) |
| got fiber (q order: 0, t/o: 20, lifo 20005ff0) as expected |
| got fiber (q order: 1, t/o: 30, lifo 20005ff0) as expected |
| got fiber (q order: 2, t/o: 10, lifo 20005ff0) as expected |
| got fiber (q order: 3, t/o: 15, lifo 20005ff0) as expected |
| got fiber (q order: 4, t/o: 25, lifo 20005ff0) as expected |
