[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v4 1/3] automation: Create Yocto docker images
Add containers 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 generic docker image template to be used to automatically generate
docker files for different configurations:
- specific yocto version
- different targets (qemu arm, arm64 and x86)
- different host platforms (x86 or arm64)
During a call to 'make all', only the images for the current host
platform will be generated.
If needed, images for an other host platform can be generated manually
by calling the right make target (see make help).
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 script is to be executed in one of the docker images to build
and run a system using a Xen source tree.
Signed-off-by: Bertrand Marquis <bertrand.marquis@xxxxxxx>
---
Changes in v4:
- Rework the system to have one dockerfile template from which make will
generate the required dockerfiles for the wanted configuration
- add support for different host architectures
- Merge the generation system into one single dockerfile
- Merge patches 1 and 2 in a single patch
- Introduce CONTAINERS_EXTRA to have extra containers not built by
default (for those not used by CI but useful to users)
Changes in v3:
- limit number of jobs in yocto by default to 8 and add --num-jobs
option to the script to set a custom number of jobs
- do not copy anymore the build-yocto.sh script inside the main image so
that the current one in the repository is used when running
Changes in v2:
- add a --dump-log command line option to build-yocto.sh script to dump
the logs if an error occurs.
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.
