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.

'meta-agl' Layer Dependencies

  • poky

    URI: git://git.yoctoproject.org/poky branch : jethro tested revision: 40376446904ae3529be41737fed9a0b650ed167d

  • meta-openembedded

    URI: git://git.openembedded.org/meta-openembedded layer : meta-openembedded branch : jethro tested revision: 8ab04afbffb4bc5184cfe0655049de6f44269990

Specifically out of meta-openembedded these sub-layers are used:

  • meta-openembedded/meta-oe
  • meta-openembedded/meta-multimedia
  • meta-openembedded/meta-networking
  • meta-openembedded/meta-python

Layers

There are 5 layers in top-level meta-agl.

  • meta-agl/meta-ivi-common\ meta-ivi-common is a layer which contains common packages to AGL Distribution and other platforms for In-Vehicle Infotainment system.
  • meta-agl/meta-agl\ meta-agl is a layer which contains AGL common and middleware packages.
  • meta-agl/meta-agl-bsp\ meta-agl-bsp is a layer which contains required packages to boot AGL distribution on an emulated machine(QEMU).
  • meta-agl/meta-netboot\ meta-netboot contains the netboot initrd support recipes. 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.bbandagl-demo-platform.bb``.
