Add meta-agl-lxc layer with LXC container integration recipes, and
"agl-lxc" feature to enable its use. The changes are based on the
previous prototypes by Tadao Tanikawa and the updates done for the
trial integration layers on the agl-ic-eg github by Naoto Yamaguchi,
Hiroyuki Ishii, and Jan-Simon Moeller.
The layer can be used by running aglsetup.sh with just the "agl-lxc"
feature, then building lxc-host-image-demo with bitbake.
Notes:
- The agl-lxc feature enables a "agl-container-guest" multiconfig
configuration for building the guest image(s). This suffices for
demonstrating integrated builds with multiconfig, but may change
in the future with extension of aglsetup.sh to add more
flexibility.
- There are guest-image-minimal and guest-image-cluster-demo recipes
that are intended as a base container template and a demo of its
use. The cluster-demo image contains the demo cluster reference
UI application, and is roughly equivalent to what is named
cluster-guest in the agl-ic-eg trial integration configuration.
- There are likewise lxc-host-image-minimal and lxc-host-image-demo
images. The host demo is configured to pull in the cluster-demo
guest image, and configuration has been added such that it will
automatically boot and start the cluster reference UI application.
- Unlike previous work where the guest container image is added to
the host image via a recipe that packages up the guest image's
contents, a more direct scheme is used where the guest image is
unpacked inside the host image rootfs via the use of the
ROOTFS_POSTPROCESS_COMMAND mechanism. This avoids some hassles
around potentially mismatched user and group id lists in the host
and guest images, with the additional benefit of being faster.
However, using this scheme is to some degree only necessary due to
the use of LXC with unpacked guest image hierarchies. With other
container tooling that uses e.g. OCI images, a revert to using
packages may be preferable.
- The reusable logic in the lxc-host-image-minimal recipe makes some
assumptions wrt naming. They are:
- guest image names have the format guest-image-<name>
- guest images have a corresponding LXC configuration file recipe
with the name lxc-config-<name>
The intent is to simplify reuse of the base minimal recipes, but
this can be reworked if deemed too restrictive.
- packagegroups for e.g. pipewire and weston have purposefully not
been defined at this time. It seems better to wait until it is
more obvious how useful they would be.
Limitations:
- The host image is currently rebuilt every time to work around an
issue with multiconfig dependencies that is being investigated
upstream. This can hopefully be removed in the near future.
- The demo images are currently in meta-agl-lxc for convenience.
It may make more sense for them to reside in another location to
ease shifting some things into meta-agl.
- At the moment, only qemux86-64 has been tested. The changes to
enable host and guest configuration tweaks for the rcar3 BSP need
further investigation and discussion on where they should be
maintained.

Jailhouse is a partitioning hypervisor based on Linux. It is able to run
bare-metal applications or (adapted) operating systems besides Linux.
For this purpose, it configures CPU and device virtualization features
of the hardware platform in a way that none of these domains, called
"cells" here, can interfere with each other in an unacceptable way.
This layer adds the Jailhouse package into AGL and also appends the BSPs
to allow it to run. Currently, Raspberry Pi 4 and QEMU x86-64 targets
are supported.
To enable Jailhouse and include it in the image, the AGL feature
agl-jailhouse must be enabled.

The link to the "Initializing Your Build Environment" in
the "Getting Started" area was broken. Fixed it.

I added the "meta-agl-devel.md" file to a new branch named
"sandbox/scottrif29/scottdocs". This file replaces the original
README.md file.
