| Title: Offload to the Kernel Service Fiber |
| |
| Description: |
| |
| This test verifies that the microkernel task_offload_to_fiber() API operates as |
| expected. |
| |
| This test has two tasks that increment a counter. The routine that |
| increments the counter is invoked from _k_server() due to the two tasks |
| calling task_offload_to_fiber(). The final result of the counter is expected |
| to be the the number of times task_offload_to_fiber() was called to increment |
| the counter as the incrementing was done in the context of _k_server(). |
| |
| This is done with time slicing both disabled and enabled to ensure that the |
| result always matches the number of times task_offload_to_fiber() is called. |

| 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 |
| |

| Sample Output: |
| |
| tc_start() - Test Microkernel Critical Section API |
| |
| Obtained expected <criticalVar> value of 10209055 |
| Enabling time slicing ... |
| Obtained expected <criticalVar> value of 15123296 |
