meta-agl, the Yocto layer for Automotive Grade Linux Distribution
=================================================================
This layer's purpose is ... [TBD]
Layer Dependencies

URI: git://git.openembedded.org/meta-openembedded

Layers
------
There are 2 sub-layers in top-level `meta-agl`.
`meta-agl` is a layer which contains AGL common and middleware packages.
> meta-agl/meta-agl
`meta-agl-bsp` is a layer which contains required packages to boot AGL distribution on an emulated machine(QEMU).
> meta-agl/meta-agl-bsp
Packagegroups
-------------
AGL package group design:
These are the top-level packagegroups for AGL Distribution.
> packagegroup-agl-core (basic/common packages out of oe-core)
> packagegroup-agl-ivi (middlewares for AGL IVI)
Each package group can contain sub-package groups like these.
> packagegroup-agl-core-multimedia
> packagegroup-agl-core-connectivity
> ...
> packagegroup-agl-ivi-multimedia
> packagegroup-agl-ivi-connectivity
> ...
The recipe for `packagegroup-agl-core-*.bb` will contain common packages between meta-agl, meta-ivi and meta-tizen.
> directory: meta-agl/meta-agl/recipes-core/packagegroups
> recipes : packagegroup-agl-core-[subsystem].bb
The "packagegroups-agl-ivi-*" will contain AGL specific middleware packages.
> directory: meta-agl/meta-agl/recipes-ivi/packagegroups
> recipes : packagegroup-agl-ivi-[subsystem].bb
Supported Machine
-----------------
* QEMU (x86-64) - emulated machine: qemux86-64
Supported Target of bitbake
------------------------
* `agl-image-ivi` The baseline image of AGL Distributions
* `agl-image-minimal` For internal use to develop distribution (experimental)
* `agl-image-weston` For internal use to develop distribution (experimental)
Build a QEMU image
------------------
You can build a QEMU image using the following steps:
1. Export TEMPLATECONF to pick up correct configuration for the build
> $ export TEMPLATECONF=/full/path/to/meta-agl/meta-agl/conf
2. Rune the following command:
> $ source poky/oe-init-build-env
3. Build the minimal image of AGL Distribution
> $ bitbake agl-image-ivi
4. Run the emulator
> $ PATH_TO_POKY/poky/scripts/runqemu agl-image-ivi qemux86-64
For large screen:
> $ PATH_TO_POKY/poky/scripts/runqemu agl-image-ivi qemux86-64 bootparams="uvesafb.mode=1280x720-32"
5. Some weston samples are available from weston terminal.
