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.
10 Furthermore, `meta-agl` does not include additional components, such
11 as security, which are part of the
12 `meta-agl-extra` layer.
16 The `meta-agl` layer itself contains many sub-layers and files.
17 Following is a "tree" look at the layer:
25 ├── meta-agl-profile-cluster
26 ├── meta-agl-profile-cluster-qt5
27 ├── meta-agl-profile-core
28 ├── meta-agl-profile-graphical
29 ├── meta-agl-profile-graphical-html5
30 ├── meta-agl-profile-graphical-qt5
31 ├── meta-agl-profile-hud
32 ├── meta-agl-profile-telematics
33 ├── meta-app-framework
42 This list provides some overview information on the files and sub-layers
45 * `docs`: Contains files that support AGL documentation.
46 * `meta-agl`: Contains layer configuration for the `meta-agl` layer.
47 * `meta-agl-bsp`: Contains adaptations for recipes and required packages
48 to boot an AGL distribution on targeted hardware and emulation (i.e. QEMU).
49 * `meta-agl-distro`: Contains distro configuration and supporting scripts.
50 * `meta-agl-profile-cluster`: The middleware for the AGL cluster profile.
51 The set of packages required for AGL Cluster Distribution.
52 Profiles include support for Wayland images.
53 * `meta-agl-profile-cluster-qt5`: The middleware for the AGL Qt5-based cluster profile.
54 The set of packages required for AGL Qt5-based Cluster Distribution.
55 Profiles include support for Wayland images with Qt5.
56 * `meta-agl-profile-core`: Configuration and recipes for the AGL core profiles.
57 * `meta-agl-profile-graphical`: Configuration and recipes supporting graphical user
59 * `meta-agl-profile-graphical-html5`: Configuration and recipes supporting profiles
60 with HTML user interface support.
61 * `meta-agl-profile-graphical-qt5`: Configuration and recipes supporting profiles
62 with Qt5-based user interface support.
63 * `meta-agl-profile-hud`: Configuration and recipes supporting profiles with
64 Head-Up-Display (HUD) support.
65 * `meta-agl-profile-telematics`: Configuration and recipes supporting profiles with
67 * `meta-app-framework`: Configuration and recipes supporting the AGL Application
69 * `meta-netboot`: Contains recipes and configuration adjustments to allow network
70 boot through network block device (NBD) since network file system (NFS) does not
71 support security labels.
72 * `meta-security`: Configuration and recipes supporting security applications.
73 * `scripts`: AGL development setup and support scripts.
74 * `templates`: Base, feature, and machine templates used in the AGL development

93 packagegroup-agl-core-speech-services.bb
95 The previous list of Packagegroups are used to create the `agl-image-minimal` image,
96 which is a small image just capable of allowing a device to boot.
98 Subsystem should maintain packagegroup-agl-core-[subsystem].bb which should
99 hold sufficient packages to build `agl-image-minimal`.
101 * packagegroup-agl-image-ivi

111 packagegroup-agl-ivi-speech-services.bb
113 The previous list of Packagegroups are used to create the `agl-image-ivi`
114 image, which is a baseline image (i.e. Service Layer and Operating System
115 Layer defined in AGL Spec v1.0) for the AGL profiles.
117 * packagegroup-agl-test.bb
119 Additional tools used in QA tests (for agl-image*-qa).

136 The previous Packagegroups pick up some packages from upstream
138 [GENIVI Alliance](https://www.genivi.org/) and others.
139 The `meta-ivi-common` layer produces no image.
140 All the Packagegroups in this layer are aggregated to `packagegroup-ivi-common-core`,
141 which is included by the images and the two recipes `agl-image-ivi.bb` and `agl-demo-platform.bb`.
