# **README.md for the 'meta-agl' layer** **See README-AGL.md for general information about Automotive Grade Linux.** ## meta-agl, the core layer for Automotive Grade Linux Distribution AGL is creating an automotive specific Linux distribution that unifies the software that has been written in a number of places already, such as GENIVI and Tizen IVI. The layer 'meta-agl' provides a minimal set of software to boot system of AGL Distribution. 'meta-agl' is the minimal core which is used build AGL profiles on top of it. Especially there is no reference UI included which is part of 'meta-agl-demo'. Additional components like the security framework are part of 'meta-agl-extra'. The AGL community appreciates feedback, ideas, suggestion, bugs and documentation just as much as code. Please join the irc conversation at the #automotive channel on irc.freenode.net and our mailing list.

This is needed in case of booting over the network as NFS does not support the securitylabels. ## Packagegroups AGL package group design: * packagegroup-agl-image-minimal packagegroup-agl-core-automotive.bb packagegroup-agl-core-connectivity.bb packagegroup-agl-core-graphics.bb packagegroup-agl-core-kernel.bb packagegroup-agl-core-multimedia.bb packagegroup-agl-core-navi-lbs.bb packagegroup-agl-core-os-commonlibs.bb packagegroup-agl-core-security.bb packagegroup-agl-core-speech-services.bb These are for making image ``agl-image-minimal`` which is small image just capable of allowing a device to boot. Subsystem should maintain packagegroup-agl-core-[subsystem].bb which should hold sufficient packages to build ``agl-image-minimal``. * packagegroup-agl-image-ivi packagegroup-agl-ivi-automotive.bb packagegroup-agl-ivi-connectivity.bb packagegroup-agl-ivi-graphics.bb packagegroup-agl-ivi-kernel.bb packagegroup-agl-ivi-multimedia.bb packagegroup-agl-ivi-navi-lbs.bb packagegroup-agl-ivi-os-commonlibs.bb packagegroup-agl-ivi-security.bb packagegroup-agl-ivi-speech-services.bb These are for making image ``agl-image-ivi`` which is baseline for the profiles of AGL distro. 'Baseline' means Service Layer and Operating System Layer defined in AGL Spec v1.0. * packagegroup-agl-test.bb Additional tools used in QA tests (for agl-image*-qa). * packagegroup-ivi-common* packagegroup-ivi-common-core-automotive.bb packagegroup-ivi-common-core.bb packagegroup-ivi-common-core-connectivity.bb packagegroup-ivi-common-core-graphics.bb packagegroup-ivi-common-core-kernel.bb packagegroup-ivi-common-core-multimedia.bb packagegroup-ivi-common-core-navi-lbs.bb packagegroup-ivi-common-core-os-commonlibs.bb packagegroup-ivi-common-core-security.bb packagegroup-ivi-common-core-speech-services.bb packagegroup-ivi-common-test.bb These are for picking up some packages from upstreams like GENIVI/Tizen/Others. The layer of ``meta-ivi-common`` has no image to build, all packagegroups are aggregated to ``packagegroup-ivi-common-core' and it is included by images, ``agl-image-ivi.bb`` and ``agl-demo-platform.bb``. ## Supported Machines See [docs.automotivelinux.org](http://docs.automotivelinux.org)
