| Title: Low Resolution Timer |
| |
| Description: |
| |
| This test verifies the following low resolution microkernel timer APIs operate |
| as expected: |
| task_timer_alloc (), task_timer_free() |
| task_timer_start(), task_timer_restart(), task_timer_stop() |
| sys_tick_delta(), sys_tick_get_32() |
| |
| Also verifies the nanokernel timeouts can work alongside the microkernel timers. |
| |

| |
| Building and Running Project: |
| |
| This microkernel 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 |
| |

| Starting timer tests |
| =================================================================== |
| Test the allocation of timers. |
| Test the one shot feature of a timer. |
| test nano_task_fifo_get with timeout > 0 |
| nano_task_fifo_get timed out as expected |
| nano_task_fifo_get got fifo in time, as expected |
| testing timeouts of 5 fibers on same fifo |
| got fiber (q order: 2, t/o: 10, fifo 00109134) as expected |
| got fiber (q order: 3, t/o: 15, fifo 00109134) as expected |
| got fiber (q order: 0, t/o: 20, fifo 00109134) as expected |
| got fiber (q order: 4, t/o: 25, fifo 00109134) as expected |
| got fiber (q order: 1, t/o: 30, fifo 00109134) as expected |
| testing timeouts of 9 fibers on different fifos |
| got fiber (q order: 0, t/o: 10, fifo 00109140) as expected |
| got fiber (q order: 5, t/o: 15, fifo 00109134) as expected |
| got fiber (q order: 7, t/o: 20, fifo 00109134) as expected |
| got fiber (q order: 1, t/o: 25, fifo 00109134) as expected |
| got fiber (q order: 8, t/o: 30, fifo 00109140) as expected |
| got fiber (q order: 2, t/o: 35, fifo 00109134) as expected |
| got fiber (q order: 6, t/o: 40, fifo 00109134) as expected |
| got fiber (q order: 4, t/o: 45, fifo 00109140) as expected |
| got fiber (q order: 3, t/o: 50, fifo 00109140) 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, fifo 00109134) as expected |
| got fiber (q order: 1, t/o: 30, fifo 00109134) as expected |
| got fiber (q order: 2, t/o: 10, fifo 00109134) as expected |
| got fiber (q order: 3, t/o: 15, fifo 00109134) as expected |
| got fiber (q order: 4, t/o: 25, fifo 00109134) as expected |
| =================================================================== |
| PASS - test_fifo_timeout. |
| Test that a timer does not start. |
| Test the periodic feature of a timer |
| Test the stopping of a timer |
| Verifying the nanokernel timeouts worked |
| =================================================================== |
| PROJECT EXECUTION SUCCESSFUL |
