| Title: Private FIFOs |
| |
| Description: |
| |
| This test verifies that the microkernel FIFO APIs operate as expected. |
| This also verifies the mechanism to define private FIFO and its usage. |
| |
| -------------------------------------------------------------------------------- |
| 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 |
| |
