| Title: Synchronisation |
| |
| Description: |
| |
| A simple application that demonstates basic sanity of the microkernel. |
| Two tasks (A and B) take turns printing a greeting message to the console, |
| and use sleep requests and semaphores to control the rate at which messages |
| are generated. This demonstrates that microkernel scheduling, communication, |
| and timing are operating correctly. |

| 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 |
| |
