| :name: POSIX Philosophers |
| |
| Implement a solution to the Dining Philosophers problem using the POSIX API. |
| |
| Overview |
| ******** |
| |
| This sample implements Zephyr's :zephyr:code-sample:`dining-philosophers` sample using the |
| :ref:`POSIX API <posix_support>`. The source code for this sample can be found under |
| :file:`samples/posix/philosophers`. |
| |
| Building and Running |
| ******************** |
| |
| This project outputs to the console. It can be built and executed on QEMU as follows: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/posix/philosophers |
| :host-os: unix |
| :board: qemu_riscv64 |
| :goals: run |
| :compact: |
| |
| Sample Output |
| ============= |
| |
| .. code-block:: console |
| |
| Philosopher 0 [P: 3] HOLDING ONE FORK |
| Philosopher 1 [P: 2] HOLDING ONE FORK |
| Philosopher 2 [P: 1] EATING [ 1900 ms ] |
| Philosopher 3 [P: 0] THINKING [ 2500 ms ] |
| Philosopher 4 [C:-1] THINKING [ 2200 ms ] |
| Philosopher 5 [C:-2] THINKING [ 1700 ms ] |
| |
| Exit QEMU by pressing :kbd:`CTRL+A` :kbd:`x`. |
| |
| Debugging |
| ********* |
| |
| Like the original philosophers sample, the POSIX variant also enables |
| :kconfig:option:`CONFIG_DEBUG_THREAD_INFO` by default. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/philosophers |
| :host-os: unix |
| :board: <board_name> |
| :goals: debug |
