| # kernel/phys -- Physical memory mode code for Zircon |
| |
| This subdirectory contains code to support the "phys" environments for Zircon. |
| The [`lib/arch`] overview provides a good description of what the various |
| environments are and what constraints each has. |
| |
| The main uses for this code are physboot, boot shims, and tests for those. |
| In the future it will also cover a variety of EFI cases. |

| [`lib/arch`]: ../lib/arch |
| |
| ## Testing |
| |
| The project uses ZBI tests, built in all product configurations, including |
| `bringup` and `core`. A basic set of tests can be executing by running the |
| command: |
| |
| ```sh |
| fx run-zbi-test zbi-phys-unittests |
| ``` |
| |
| Other ZBI tests also exist in the project. The full list can be viewed by |
| running: |
| |
| ```sh |
| fx run-zbi-test | grep //zircon/kernel/phys |
| ``` |
