Introduction

The meta-agl layer provides the minimal set of software to boot an AGL Distribution system. You use this layer as the minimal core on which to build AGL profiles.

NOTE: The meta-agl layer does not include a reference UI. The reference UI is included as part of the meta-agl-demo layer.

Sub-Layers

The meta-agl layer itself contains many sub-layers and files. Following is a "tree" look at the layer:

|-- LICENSE
|-- LICENSE.GPL-2.0-only
|-- LICENSE.MIT
|-- README-AGL.md
|-- README.md -> meta-agl.md
|-- agl-layers-overview.md
|-- docs
|-- meta-agl-bsp
|-- meta-agl-core
|-- meta-agl-core-test
|-- meta-agl-ic
|-- meta-agl-ivi
|-- meta-agl.md
|-- meta-app-framework
|-- meta-netboot
|-- meta-pipewire
|-- scripts
`-- templates

This list provides some overview information on the files and sub-layers in meta-agl:

• LICENSE* : licenses of the various components.
• README* : RTFM
• agl-layers-overview.md: references to the various layers that make up AGL
• docs: Contains files that support AGL documentation.
• meta-agl-bsp: Contains adaptations for recipes and required packages to boot an AGL distribution on targeted hardware and emulation (i.e. QEMU).
• meta-agl-core: This is the core layer with essential recipes and the distro.
• meta-agl-core-test: recipes supporting qa images (separate layer due to external dependencies)
• meta-agl-ic: Instrument Cluster platform
• meta-agl-ivi: IVI platform
• meta-app-framework: Configuration and recipes supporting the AGL Application Framework.
• meta-netboot: Contains recipes and configuration adjustments to allow network boot through network block device (NBD) since network file system (NFS) does not support security labels.
• meta-pipewire: Configuration and recipes supporting pipewire as audio manager
• scripts: AGL development setup and support scripts.
• templates: Base, feature, and machine templates used in the AGL development environment.
