Ok, so not full time, but hopefully enough time to help spread some
knowledge.

We have https://gitlab.com/xen-project/xen/pipelines which runs a load
of containerised builds. How easy is it to set up a containerised
RISC-V cross-compiler environment?
The test step also boots Xen under Qemu software emulation to check that
we don't have any boot-time screamers. A reasonable second step might
be to have start_xen() panic() at the end, and check for that in the
console log, which would allow for some kind of boot testing before
getting all the way to "and here is dom0 ready to run".
All configuration is in .gitlab-ci.yml and automation/.
