It also require a linux kernel that have below AF_XDP RFC patches be applied. https://patchwork.ozlabs.org/patch/867961/ https://patchwork.ozlabs.org/patch/867960/ https://patchwork.ozlabs.org/patch/867938/ https://patchwork.ozlabs.org/patch/867939/ https://patchwork.ozlabs.org/patch/867940/ https://patchwork.ozlabs.org/patch/867941/ https://patchwork.ozlabs.org/patch/867942/ https://patchwork.ozlabs.org/patch/867943/ https://patchwork.ozlabs.org/patch/867944/ https://patchwork.ozlabs.org/patch/867945/ https://patchwork.ozlabs.org/patch/867946/ https://patchwork.ozlabs.org/patch/867947/ https://patchwork.ozlabs.org/patch/867948/ https://patchwork.ozlabs.org/patch/867949/ https://patchwork.ozlabs.org/patch/867950/ https://patchwork.ozlabs.org/patch/867951/ https://patchwork.ozlabs.org/patch/867952/ https://patchwork.ozlabs.org/patch/867953/ https://patchwork.ozlabs.org/patch/867954/ https://patchwork.ozlabs.org/patch/867955/ https://patchwork.ozlabs.org/patch/867956/ https://patchwork.ozlabs.org/patch/867957/ https://patchwork.ozlabs.org/patch/867958/ https://patchwork.ozlabs.org/patch/867959/ There is no clean upstream target yet since kernel patch is still in RFC stage, The purpose of the patchset is just for anyone that want to eveluate af_xdp with DPDK application and get feedback for further improvement. To try with the new PMD 1. compile and install the kernel with above patches applied. 2. configure $LINUX_HEADER_DIR (dir of "make headers_install") and $TOOLS_DIR (dir at /tools) at driver/net/af_xdp/Makefile before compile DPDK. 3. make sure libelf and libbpf is installed. BTW, performance test shows our PMD can reach 94%~98% of the orignal benchmark when share memory is enabled.
