Oh, another spot that needs special handling ... I see Alexander
already sent a patch (thanks!), but anyway, this is a good
indication that we're missing some test coverage in the CI.
Are there any loongarch kernel images available for public download
somewhere? If so, we really should add an avocado regression test
for this - since as far as I can see, we don't have any tests for
loongarch in tests/avocado yet?
we can get some binarys at:

I'm not sure that avacodo testing can be done using just the kernel.
Is a full loongarch system required?
No, you don't need a full distro installation, just a kernel with
ramdisk (which is also available there) is good enough for a basic
test, e.g. just check whether the kernel boots to a certain point is
good enough to provide a basic sanity test. If you then can also get
even into a shell (of the ramdisk), you can check some additional
stuff in the sysfs or "dmesg" output, see for example
tests/avocado/machine_s390_ccw_virtio.py which does such checks with a
kernel and initrd on s390x.
Thanks for you suggestion .
We will add a loongarch basic test on tests/avacode.
Thanks.
