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.

Sub-Layers

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

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-drm-lease: The recipes for supporting display isolating feature (DRM master sharing).
• meta-agl-flutter: The recipes for AGL Flutter support.
• meta-agl-ic: The recipe set for Instrument Cluster platform.
• meta-agl-ivi: The recipe set for IVI platform.
• meta-agl-kuksa-val: The recipes for AGL Vehicle API support using kuksa.
• meta-app-framework: The recipes for AGL IVI 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.
