Hello Driver Sample

This sample project contains a “Hello, World” driver component that showcases the bare scaffolding necessary to register and load a driver component in Fuchsia.

Building

To build the driver component, run the following command:

tools/bazel build --config=fuchsia_x64 //src/example_driver:pkg

Running

Use the following commands to load the driver component on a target device:

Load the example_driver component:

tools/bazel run --config=fuchsia_x64 //src/example_driver:pkg.component

Open the device log viewer:
```
tools/ffx log --filter example_driver
```

You should see the driver component say hello:

[driver_manager.cm][I]: [driver_runner.cc:377] Binding fuchsia-pkg://bazel.pkg.component/example_driver#meta/example_driver.cm to acpi-FWCF-passthrough
[example-driver,driver][I]: [example_driver.cc:51] **** Hello world ****

Testing

Use the following command to run the unit tests on a target device:

tools/bazel test --config=fuchsia_x64 //src/example_driver:test_pkg
