Please split this patch separating the really minimum support (getting EAL and main libraries to build, disabling the rest that is "broken" for s390x) then adding more components support in later patches. RISC V and LoongArch "recent" additions are good examples. https://patchwork.dpdk.org/project/dpdk/list/?series=23380&state=%2A&archive=both https://patchwork.dpdk.org/project/dpdk/list/?series=24969&state=%2A&archive=both - We need one maintainer for this new architecture. - You'll notice that the DPDK CI reported issues, please fix them. - What are the plans in terms of CI? We need some compilation testing and ideally some regular runtime testing. Maybe you can reach out to IBM PPC DPDK guys, like David Christensen, to see what they are doing. -- David Marchand
