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: https://git.yoctoproject.org/cgit/cgit.cgi/meta-security
  • Branch: "master"
  • Tested Revision: See the default.xml manifest file for the AGL-repo repository for revision information.

• AGL's meta-app-framework Layer within the meta-agl Layer:

  • URI: https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL/meta-agl.git
  • Branch: "master"

The agl-sota Feature:

• Here Technologies' meta-updater Layer:

  • URI: https://github.com/advancedtelematic/meta-updater/
  • Branch: "thud"

• Here Technologies' meta-updater-qemux86-64 Layer:

  • URI: https://github.com/advancedtelematic/meta-updater-qemux86-64/
  • Branch: "thud"

• OpenEmbedded's meta-openembedded Layer:

  • URI: https://github.com/openembedded/meta-openembedded
  • Branch: "thud"
  • Tested Revision: See the default.xml manifest file for the AGL-repo repository for revision information.

  Specifically, out of meta-openembedded, these sub-layers are used:

  • meta-filesystems
  • meta-oe
  • meta-python

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: "octopus"

Packagegroups

AGL DEMO Platform's packagegroups 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.

  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 three 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.
