[PATCH 0/3] automation: build qemu-system-aarch64 and use it for tests

Posted by Stefano Stabellini 3 years, 10 months ago

Hi all,

Currently we are using Debian's qemu-system-aarch64 for our tests.
However, sometimes it crashes. See for instance
https://gitlab.com/xen-project/people/andyhhp/xen/-/jobs/939556527. It
is hard to debug and even harder to apply any fixes to it.

Instead, build our own QEMU as one of our test-artifacts, which are only
built once, then imported into each pipeline via phony jobs. Use the
provided qemu-system-aarch64 binary for our arm64 tests.


Stefano Stabellini (3):
      automation: add qemu-system-aarch64 to test-artifacts
      automation: add a job to import qemu-system-aarch64 into the pipeline
      automation: use test-artifacts/qemu-system-aarch64 instead of Debian's

I do wonder if there is a way to not build QEMU during every pipeline
run though...

It does not build QEMU every pipeline! It only imports it into the
pipeline by copying the QEMU binary from a container. The container with
the QEMU binary is not built every time. We could build it once a month
or so like the build containers.
