  1. Thank you for merging! I prepared kernel with AF_XDP enabled and my test application works fine: sock0@wan:0 rxdrop pps pkts 1.00 rx 9,310 9,323 tx 0 0 Packet rate aren't impressive but my packet generator works over WIFI and Powerline. I do not expect performance here That's great place for future improvements!
  2. I created PR to enable this feature:
  3. Well, I noticed one issues with this kernel. Any chance to enable kernel configuration option CONFIG_XDP_SOCKETS in kernel for EspressoBin? We participated in testing this feature when it was in bpf-next and it worked fine on our ARM64 machines (Thunder X machines from Cavium). I expect that it should work on EspressoBin fine too. I tried test app for AF_XDP and it does not work: libbpf: failed to create map (name: 'xsks_map'): Invalid argument libbpf: failed to load object './xdpsock_user_kern.o' And dump from strace: 2909 bpf(BPF_MAP_CREATE, {map_type=BPF_MAP_
  4. Hello! Thank you for porting Ubuntu 18.04 to EspressoBin! It works great I noticed only small issues with systremd: [FAILED] Failed to start Wait for Network to be Configured. See 'systemctl status systemd-networkd-wait-online.service' for details.

  10. Looks like 4.16 kernel has number of nice features for EspressoBin (cpu scaling, crypto). Do you have any plans to offer builds on this kernel?
  11. Just installed Ubuntu 16.04 with 4.14.38-mvebu64. It works REALLY great! Thank you so much for your effort!
