With a rootfs built using libbpf's BPF CI [1], we can run specific tests as follows:

$ ../libbpf-ci/rootfs/mkrootfs_debian.sh --arch ppc64el --distro noble $ PLATFORM=ppc64el CROSS_COMPILE=powerpc64le-linux-gnu- \ tools/testing/selftests/bpf/vmtest.sh \ -l libbpf-vmtest-rootfs-*-noble-ppc64el.tar.zst \ -- ./test_progs -t verifier_array_access

Does not include a DENYLIST or support for KVM for now.
