# Build a Linux kernel for use in testing. We enable the VKMS module so we can
# predictably test the DRM backend in the absence of real hardware. We lock the
# version here so we see predictable results.
#
# To run this we use virtme, a QEMU wrapper: https://github.com/amluto/virtme
#
# virtme makes our lives easier by abstracting handling of the console,
# filesystem, etc, so we can pretend that the VM we execute in is actually
# just a regular container.
#
# The reason why we are using a fork here is that it adds a patch to have the
# --script-dir command line option. With that we can run scripts that are in a
# certain folder when virtme starts, which is necessary in our use case.
#
# The upstream also has some commands that could help us to reach the same
# results: --script-sh and --script-exec. Unfornutately they are not completely
# implemented yet, so we had some trouble to use them and it was becoming
# hackery.
#
# The fork pulls in this support from the original GitHub PR, rebased on top of
# a newer upstream version which fixes AArch64 support.

# please be prepared for some of the tests to change output, which will need to
# be manually inspected for correctness.
