[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v1 2/4] automation: Add elements for Yocto test and run
Add a container suitable to run yocto kirkstone build based on ubuntu
22.04. It contains all packages required by Yocto and a checkout of the
layers required to build Xen with Yocto.
Add a build script to build and run xen on qemu using Yocto.
The script supports arm32, arm64 and x86_64 and checks that dom0 is
properly booting. At this stage this does not run any guest on top of
dom0.
The build script is currently in the same directory than the docker
files so that it can be included directly in the image. This is required
for the next step which creates images with an initial cache content to
speed up testing.
Signed-off-by: Bertrand Marquis <bertrand.marquis@xxxxxxx>
---
Changes in v1:
- add --image command line argument to build-yocto.sh to allow building
something different than xen-image-minimal.
- modify dockerfile to have one layer per line and make it easier to add
other. I kept the for loop to keep the number of docker steps lower
- update commit message to warn that no guest are tested.
- fix build-yocto script to properly return with an error if expect
script ends up in timeout or EOF.
