7 The `meta-agl-devel` layer contains components that are being tested or
9 The layer also contains software packages that Original Equipment
10 Manufacturers (OEMs) need but are not included in the AGL software.
14 The `meta-agl-devel` layer contains the following files and sub-layers:
18 ├── meta-agl-telemetry
19 ├── meta-audio-4a-framework
20 ├── meta-audio-soundmanager-framework
22 ├── meta-gstrecorder-rcar-gen3
23 ├── meta-hmi-framework
24 ├── meta-oem-extra-libs
29 The following list provides a summary of these sub-layers:
31 * `meta-agl-telemetry`: Provides the smallest AGL image.
32 The image is designed to be used when a device requires restricted
33 scope of responsibilites (e.g. collecting vehicle telemetry).
35 * `meta-audio-4a-framework`: A collection of recipes used for the
36 first integration of 4A (i.e. Advanced AGL Audio Architecture).
38 * `meta-pipewire`: A collection of recipes used for the integration
39 of the pipewire sound system.
41 * `meta-audio-soundmanager-framework`: Supports the Soundmanager
42 Audio Framework features, which maps to the `agl-audio-soundmanager-framework`
45 * `meta-egvirt`: The AGL Virtualization Expert Group (EG-VIRT) layer.
46 This layer supports the design, test, implementation, and assessment
47 of virtualization technologies (e.g. containers, hypervisors, system
48 partitioners, and so forth) aimed at AGL ARMv8 and Intel platforms.
50 * `meta-gstrecorder-rcar-gen3`: Supports streaming audio and video for
51 the Pro and Premier board kits (e.g.
52 [Renesas R-Car Starter Kit Pro Board](https://www.elinux.org/R-Car/Boards/M3SK)
54 [Renesas R-Car Starter Kit Premier Board](https://www.elinux.org/R-Car/Boards/H3SK)).
56 * `meta-hmi-framework`: Provides AGL's Human Machine Interface (HMI) framework
57 through resource management consisting of sounds, windows, and input control.
58 For more information, see the
59 [HMI-Framework Page](https://wiki.automotivelinux.org/hmiframework) of the
62 * `meta-oem-extra-libs`: Provides libraries and software packages needed by
63 OEMs but not provided by the AGL software.
65 * `templates`: Feature templates that support the `meta-agl-devel` layer.
67 ## Additional Sub-Layer Information
69 This section provides additional information for the `meta-egvirt`,
70 `meta-oem-extra-libs`, and `meta-hmi-framework` layers.
72 ### Virtualization Support
74 The `meta-egvirt` layer enables virtualization support in AGL.
75 The AGL Virtualization Expert (EG-VIRT) group is responsible
76 for design and implementation of AGL virtualization solutions
77 (.e.g the Virtualization platform architecture of AGL).
78 You can read about EG-VERT's efforts on the
79 "[Virtualization Expert Group's](https://wiki.automotivelinux.org/eg-virt)"
82 Additionally, you can learn more about virtualization as it applies to AGL
84 "[The Automotive Grade Linux Software Defined Connected Car Architecture](https://www.automotivelinux.org/wp-content/uploads/sites/4/2018/06/agl_software_defined_car_jun18.pdf)"
87 ### OEM Extra Libraries
89 The `meta-oem-extra-libs` layer provides additional software packages many OEMs need
90 but are not part of the AGL source.
91 Following is the list of packages this layer provides:
113 To add these packages to your library, you need to include the
114 `agl-oem-extra-libs` AGL feature when you initialize your build
115 environment using the `aglsetup.sh` script.
117 For information on how to use the `aglsetup.sh` script to initialize
118 your build environment, see the
119 "[Initializing Your Build Environment](../../01_Getting_Started/02_Building_AGL_Image/04_Initializing_Your_Build_Environment.md)"
122 Once you have included the AGL feature, you can build your image.
126 The `meta-hmi-framework` layer supports the Human-Machine Interface (HMI) Framework.
127 The HMI-Framework is the User Interface (UI) to control the Infotainment System.
128 Work continues to close the gap between the user experience of a smart phone
129 and the Infotainment System in a vehicle, for example.
131 You can find more out about HMI Framework progress on the
132 "[HMI Framework](https://wiki.automotivelinux.org/hmiframework)" page on the AGL Wiki.
134 To add HMI Framework support to your image, you need to include the
135 `hmi-framework` AGL feature when you initialize your build
136 environment using the `aglsetup.sh` script.
138 For information on how to use the `aglsetup.sh` script to initialize
139 your build environment, see the
140 "[Initializing Your Build Environment](../../01_Getting_Started/02_Building_AGL_Image/04_Initializing_Your_Build_Environment.md)"
143 Once you have included the AGL feature, you can build your image.
