+[packagegroups](https://www.yoctoproject.org/docs/3.1.2/dev-manual/dev-manual.html#usingpoky-extend-customimage-customtasks) +consist of the following: + +### packagegroup-agl-demo-platform + +This packagegroup is used for generating the `agl-demo-platform` image, +which is the full image for the AGL distributions IVI profile. +You can see the recipe (i.e. `agl-demo-platform.bb`) that installs +the `packagegroup-agl-demo-platform` packagegroup +[here](https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-platform/images/agl-demo-platform.bb). + +As meta-agl's design of packagegroups, the `agl-demo-platform.bb` recipe installs +only `packagegroup-agl-demo-platform` and the packages of the DEMO applications. + +``agl-demo-platform`` contains the following three packagegroups: + + * `packagegroup-agl-image-minimal` + * `packagegroup-agl-image-ivi` + * `packagegroup-agl-demo-platform` + +### packagegroup-agl-appfw* + +These packagegroups contain packages for the AGL distribution's +Application Framework. +Subsystem should maintain `packagegroup-agl-appfw-[subsystem].bb`, which +should hold sufficient packages for the Application Framework. + +Subsystems also can maintain their own packagegroups using appropriate +`recipes-*/`. +For example, Qt5 has two packagegroups in `meta-agl-demo`: +`packagegroup-agl-appfw-native-qt5` and `packagegroup-agl-demo-qt-examples`, +which are under `recipes-qt/`. + +The `packagegroup-agl-appfw-native-qt5` is included by +`packagegroup-agl-appfw-native` because Qt5 belongs to native application +framework of AGL Distro. + +Because the `packagegroup-agl-demo-qt-examples` is not mandatory for +the AGL Application Framework and the AGL DEMO, the packagegroup is added +to the layer's `local.conf` file only when needed. + diff --git a/docs/3_Developer_Guides/1_AGL_Layers/4_meta-agl-devel.md b/docs/3_Developer_Guides/1_AGL_Layers/4_meta-agl-devel.md new file mode 100644 index

`meta-agl-telemetry`: Provides the smallest AGL image. + The image is designed to be used when a device requires restricted + scope of responsibilites (e.g. collecting vehicle telemetry). + +* `meta-audio-4a-framework`: A collection of recipes used for the + first integration of 4A (i.e. Advanced AGL Audio Architecture). + +* `meta-pipewire`: A collection of recipes used for the integration + of the pipewire sound system. + +* `meta-audio-soundmanager-framework`: Supports the Soundmanager + Audio Framework features, which maps to the `agl-audio-soundmanager-framework` + AGL feature. + +* `meta-egvirt`: The AGL Virtualization Expert Group (EG-VIRT) layer. + This layer supports the design, test, implementation, and assessment + of virtualization technologies (e.g. containers, hypervisors, system + partitioners, and so forth) aimed at AGL ARMv8 and Intel platforms. + +* `meta-gstrecorder-rcar-gen3`: Supports streaming audio and video for + the Pro and Premier board kits

`meta-hmi-framework`: Provides AGL's Human Machine Interface (HMI) framework + through resource management consisting of sounds, windows, and input control. + For more information, see the + [HMI-Framework Page](https://wiki.automotivelinux.org/hmiframework) of the + AGL Wiki. + +* `meta-oem-extra-libs`: Provides libraries and software packages needed by + OEMs but not provided by the AGL

+`meta-oem-extra-libs`, and `meta-hmi-framework` layers. + +### Virtualization Support + +The `meta-egvirt` layer enables virtualization support in AGL. +The AGL Virtualization Expert (EG-VIRT) group is responsible +for design and implementation of AGL virtualization solutions +(.e.g the Virtualization platform architecture of AGL). +You can read about EG-VERT's efforts on the +"[Virtualization Expert Group's](https://wiki.automotivelinux.org/eg-virt)" +page of the AGL wiki. + +Additionally, you can learn more about virtualization as it applies to AGL +by reading +"[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)" +whitepaper. + +### OEM Extra Libraries + +The `meta-oem-extra-libs` layer provides additional software packages many OEMs need +but are not part of the AGL source. +Following is the list of packages this layer provides: + + * boost + * fixesproto + * imagemagick + * iptables + * Xorg-macros + * zlib + * eglibc = glibc + * libcurl + * libgif + * libneon + * mongoose + * fuse + * protocol buffers + * bsdiff + * module-init-tools + * libcroco + * libtiff + * librsvg + * libpcap + +To add these packages to your library, you need to include the +`agl-oem-extra-libs` AGL feature when you initialize your build +environment using the `aglsetup.sh` script. + +For information on how to use the `aglsetup.sh` script to initialize +your build environment, see the +"[Initializing Your Build Environment](../getting_started/reference/getting-started/image-workflow-initialize-build-environment.html)" +section. + +Once you have included the AGL feature, you can build your image. + +### HMI Framework + +The `meta-hmi-framework` layer supports the Human-Machine Interface (HMI) Framework. +The HMI-Framework is the User Interface (UI) to control the Infotainment System. +Work continues to close the gap between the user experience of a smart phone +and the Infotainment System in a vehicle, for example. + +You can find more out about HMI Framework progress on the +"[HMI Framework](https://wiki.automotivelinux.org/hmiframework)" page on the AGL Wiki. + +To add HMI Framework support to your image, you need to include the +`hmi-framework` AGL feature when you initialize
