3 The `meta-agl` layer provides the minimal set of software
4 to boot an AGL Distribution system.
5 You use this layer as the minimal core on which to build AGL profiles.
7 **NOTE:** The `meta-agl` layer does not include a reference UI.
8 The reference UI is included as part of the
9 [`meta-agl-demo`](./meta-agl-demo.html) layer.
13 The `meta-agl` layer itself contains many sub-layers and files.
14 Following is a "tree" look at the layer:
18 |-- LICENSE.GPL-2.0-only
21 |-- README.md -> meta-agl.md
22 |-- agl-layers-overview.md
26 |-- meta-agl-core-test
30 |-- meta-app-framework
37 This list provides some overview information on the files and sub-layers
40 * LICENSE* : licenses of the various components.
42 * agl-layers-overview.md: references to the various layers that make up AGL
43 * `docs`: Contains files that support AGL documentation.
44 * `meta-agl-bsp`: Contains adaptations for recipes and required packages
45 to boot an AGL distribution on targeted hardware and emulation (i.e. QEMU).
46 * `meta-agl-core`: This is the core layer with essential recipes and the distro.
47 * `meta-agl-core-test`: recipes supporting qa images (separate layer due to external dependencies)
48 * `meta-agl-ic`: Instrument Cluster platform
49 * `meta-agl-ivi`: IVI platform
50 * `meta-app-framework`: Configuration and recipes supporting the AGL Application
52 * `meta-netboot`: Contains recipes and configuration adjustments to allow network
53 boot through network block device (NBD) since network file system (NFS) does not
54 support security labels.
55 * `meta-pipewire`: Configuration and recipes supporting pipewire as audio manager
56 * `scripts`: AGL development setup and support scripts.
57 * `templates`: Base, feature, and machine templates used in the AGL development
