7 The `meta-agl` layer provides the minimal set of software
8 to boot an AGL Distribution system.
9 You use this layer as the minimal core on which to build AGL profiles.
11 **NOTE:** The `meta-agl` layer does not include a reference UI.
12 The reference UI is included as part of the
13 [`meta-agl-demo`](3_meta-agl-demo.md) layer.
14 Furthermore, `meta-agl` does not include additional components, such
15 as security, which are part of the
16 `meta-agl-extra` layer.
20 The `meta-agl` layer itself contains many sub-layers and files.
21 Following is a "tree" look at the layer:
29 ├── meta-agl-profile-cluster
30 ├── meta-agl-profile-cluster-qt5
31 ├── meta-agl-profile-core
32 ├── meta-agl-profile-graphical
33 ├── meta-agl-profile-graphical-html5
34 ├── meta-agl-profile-graphical-qt5
35 ├── meta-agl-profile-hud
36 ├── meta-agl-profile-telematics
37 ├── meta-app-framework
46 This list provides some overview information on the files and sub-layers
49 * `docs`: Contains files that support AGL documentation.
50 * `meta-agl`: Contains layer configuration for the `meta-agl` layer.
51 * `meta-agl-bsp`: Contains adaptations for recipes and required packages
52 to boot an AGL distribution on targeted hardware and emulation (i.e. QEMU).
53 * `meta-agl-distro`: Contains distro configuration and supporting scripts.
54 * `meta-agl-profile-cluster`: The middleware for the AGL cluster profile.
55 The set of packages required for AGL Cluster Distribution.
56 Profiles include support for Wayland images.
57 * `meta-agl-profile-cluster-qt5`: The middleware for the AGL Qt5-based cluster profile.
58 The set of packages required for AGL Qt5-based Cluster Distribution.
59 Profiles include support for Wayland images with Qt5.
60 * `meta-agl-profile-core`: Configuration and recipes for the AGL core profiles.
61 * `meta-agl-profile-graphical`: Configuration and recipes supporting graphical user
63 * `meta-agl-profile-graphical-html5`: Configuration and recipes supporting profiles
64 with HTML user interface support.
65 * `meta-agl-profile-graphical-qt5`: Configuration and recipes supporting profiles
66 with Qt5-based user interface support.
67 * `meta-agl-profile-hud`: Configuration and recipes supporting profiles with
68 Head-Up-Display (HUD) support.
69 * `meta-agl-profile-telematics`: Configuration and recipes supporting profiles with
71 * `meta-app-framework`: Configuration and recipes supporting the AGL Application
73 * `meta-netboot`: Contains recipes and configuration adjustments to allow network
74 boot through network block device (NBD) since network file system (NFS) does not
75 support security labels.
76 * `meta-security`: Configuration and recipes supporting security applications.
77 * `scripts`: AGL development setup and support scripts.
78 * `templates`: Base, feature, and machine templates used in the AGL development

99 The previous list of Packagegroups are used to create the `agl-image-minimal` image,
100 which is a small image just capable of allowing a device to boot.
102 Subsystem should maintain packagegroup-agl-core-[subsystem].bb which should
103 hold sufficient packages to build `agl-image-minimal`.

117 The previous list of Packagegroups are used to create the `agl-image-ivi`
118 image, which is a baseline image (i.e. Service Layer and Operating System
119 Layer defined in AGL Spec v1.0) for the AGL profiles.
