| # Defines a Fuchsia driver package. |
| # A fuchsia_driver_package is a fuchsia_package but with extra |
| # metadata so that the drivers inside the package can be collected into a |
| # Driver Manifest. Normally, these packages will be included in the base_driver_package |
| # list and included in the Base Driver Manifest. |
| # |
| # A driver is a shared library that's placed in the /driver/ directory of the package. |
| # Drivers are normally built with the `fuchsia_driver` build target. |
| # |
| # The fuchsia_driver_package does not need to contain any components, although |
| # components placed in the package will behave normally. |
| # |
| # For more information on a fuchsia_package see: |
| # //build/components/fuchsia_package.gni |
| # |
| # Parameters: |
| # |
| # driver_components (required) |
| # A list of driver components to include in the package. |
| # Type: list(labels) |
| # |
| # package_name (optional) |
| # The name of the package. |
| # Type: string |
| # Default: target_name |
| # |
| # disable_elf_binaries_checks (optional) |
| # Set to true to disable ELF binaries verification checks. Useful |
| # if your package includes non-Fuchsia ELF binaries, or if some |
| # of them are unstripped. |
| # Type: boolean |
| # Default: false |
| # |
| # deps |
| # testonly |
