## Introduction The `meta-agl-demo` layer is the reference user interface layer for the DEMO platform of Automotive Grade Linux (AGL). The layer provides a reference platform and applications. The BitBake target name for the DEMO platform is `agl-demo-platform`, which is the full DEMO platform image. ## Layer Dependencies This section describes dependencies for the `meta-agl-demo` layer. Dependencies are grouped into base, hardware, and feature dependencies. ### Base Dependencies The `meta-agl-demo` layer has the following base dependencies: * Yocto Project Release: - URI: git://git.yoctoproject.org/poky - Branch: "rocko"<br/><br/> * AGL `meta-agl` Layer: - URI: https://gerrit.automotivelinux.org/gerrit/AGL/meta-agl - Branch: "guppy"<br/><br/> * OpenEmbedded `meta-openembedded` Layer: - Branch: "rocko" Specifically, out of `meta-openembedded`, these sub-layers are used: - `meta-oe` - `meta-multimedia` - `meta-networking` - `meta-python`<br/><br/> * Yocto Project `meta-qt5` Layer from the [OpenEmbedded Layer Index](https://layers.openembedded.org/layerindex/branch/master/layers/): - URI: https://github.com/meta-qt5/meta-qt5.git - Branch: "rocko" ### Hardware Dependencies Aside from the previously listed base dependencies, if you are using a [supported Renesas board](../getting_started/reference/getting-started/machines/renesas.html) supported Renesas board, these dependencies exist: * AGL's `meta-renesas` Layer: - URI: https://gerrit.automotivelinux.org/gerrit/AGL/meta-renesas ### Feature Dependencies The `meta-agl-demo` layer has the following AGL [feature](../getting_started/reference/getting-started/image-workflow-initialize-build-environment.html#agl-features) dependencies: * Yocto Project `meta-security` Layer: - URI: https://git.yoctoproject.org/cgit/cgit.cgi/meta-security - Branch: "rocko"<br/><br/> * AGL's `meta-app-framework` Layer Within the `meta-agl` Layer: - URI: https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl.git - Branch: "guppy" **The `agl-sota` Feature:** * AGL's `meta-sota` Layer Within the `meta-agl-extra` Layer: - URI: https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl-extra.git - Branch: "guppy"<br/><br/> * OpenEmbedded's `meta-openembedded` Layer: - URI: https://github.com/openembedded/meta-openembedded - Branch: "rocko" In particular, the `meta-openembedded` layer depends on the `meta-filesystems` sub-layer. **The `agl-netboot` Feature:** * AGL's `meta-netboot` Layer Within the `meta-agl` Layer: - URI: https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl.git - Branch: "guppy" ## Packagegroups AGL DEMO Platform's [packagegroups](https://www.yoctoproject.org/docs/2.4.4/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks) consist of the following: ### packagegroup-agl-demo-platform This packagegroup is used for generating the `agl-demo-platform` image, which is the full image for the AGL distributions IVI profile. You can see the recipe (i.e. `agl-demo-platform.bb`) that installs the `packagegroup-agl-demo-platform` packagegroup [here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb). As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs only `packagegroup-agl-demo-platform` and the packages of the DEMO applications. ``agl-demo-platform`` contains the following four packagegroups: * `packagegroup-agl-image-minimal` * `packagegroup-agl-image-ivi` * `packagegroup-agl-demo-platform` ### packagegroup-agl-appfw* These packagegroups contain packages for the AGL distribution's Application Framework. Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which should hold sufficient packages for the Application Framework. Subsystems also can maintain their own packagegroups using appropriate `recipes-*/`. For example, Qt5 has two packagegroups in `meta-agl-demo`: `packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`, which are under `recipes-qt/`. The `packagegroup-agl-appfw-native-qt5` is included by `packagegroup-agl-appfw-native` because Qt5 belongs to native application framework of AGL Distro. Because the `packagegroup-agl-demo-qt-examples` is not mandatory for the AGL Application Framework and the AGL DEMO, the packagegroup is added to the layer's `local.conf` file only when needed.
