Hi Arnaldo, Alan, After recent pahole changes [1] BPF CI fails for s390 [2]. Song Liu identified that there is a mismatch between endianness of BTF in .BTF and .BTF.base sections. I think that the correct fix should be on libbpf side, where btf__distill_base() should inherit endianness from source BTF. If there are any plans for new pahole release, could you please postpone it until current issue is resolved? (I should have a fix for this thing by tomorrow). Best regards, Eduard [1] c7b1f6a29ba1 ("btf_encoder: Add "distilled_base" BTF feature to split BTF generation") [2] https://github.com/kernel-patches/bpf/actions/runs/10622763027/job/29447973415
