stmmac: add XDP ZC support
|
expand
|
Hi, This is the v1 patch series to add XDP ZC support to stmmac driver and the changes are as listed in below summary:- 1-4/7: Refactor RX & TX buffer allocation and initialization to prepare stmmac driver for XSK RX & TX pool enabling and disabling. 5/7: Refactor stmmac_xdp_run_prog() for XDP ZC use which does not need to check for XDP program loaded. 6-7/7: XDP ZC RX and TX enabling. The above patch series have been tested using xdpsock app in samples/bpf directory on Intel mGbE controller. The DUT receives burst traffic packets generated by using pktgen_sample03_burst_single_flow.sh in samples/pktgen. ######################################################################## ========== A) RX-Only ========== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -r -S sock0@eth0:0 rxdrop xdp-skb pps pkts 1.00 rx 112161 12229475 tx 0 0 sock0@eth0:0 rxdrop xdp-skb pps pkts 1.00 rx 112280 12341779 tx 0 0 sock0@eth0:0 rxdrop xdp-skb pps pkts 1.00 rx 112358 12454155 tx 0 0 ==================================================== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -r -N -c sock0@eth0:0 rxdrop xdp-drv pps pkts 1.00 rx 681082 2616133 tx 0 0 sock0@eth0:0 rxdrop xdp-drv pps pkts 1.00 rx 681205 3297415 tx 0 0 sock0@eth0:0 rxdrop xdp-drv pps pkts 1.00 rx 681386 3978873 tx 0 0 ==================================================== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -r -z sock0@eth0:0 rxdrop xdp-drv pps pkts 1.00 rx 703915 19579779 tx 0 0 sock0@eth0:0 rxdrop xdp-drv pps pkts 1.00 rx 703766 20283768 tx 0 0 sock0@eth0:0 rxdrop xdp-drv pps pkts 1.00 rx 703383 20987229 tx 0 0 ========== B) TX-Only ========== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -t -S sock0@eth0:0 txonly xdp-skb pps pkts 1.00 rx 0 0 tx 140269 4326720 sock0@eth0:0 txonly xdp-skb pps pkts 1.00 rx 0 0 tx 140514 4467264 sock0@eth0:0 txonly xdp-skb pps pkts 1.00 rx 0 0 tx 140009 4607296 ==================================================== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -t -N -c sock0@eth0:0 txonly xdp-drv pps pkts 1.00 rx 0 0 tx 138222 3108160 sock0@eth0:0 txonly xdp-drv pps pkts 1.00 rx 0 0 tx 139629 3247872 sock0@eth0:0 txonly xdp-drv pps pkts 1.00 rx 0 0 tx 139821 3387712 ==================================================== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -t -z sock0@eth0:0 txonly xdp-drv pps pkts 1.00 rx 0 0 tx 447382 13390848 sock0@eth0:0 txonly xdp-drv pps pkts 1.00 rx 0 0 tx 447384 13838272 sock0@eth0:0 txonly xdp-drv pps pkts 1.00 rx 0 0 tx 447384 14285696 ================ C) L2 Forwarding ================ root@intel-corei7-64:~ $ ./xdpsock -i eth0 -l -S sock0@eth0:0 l2fwd xdp-skb pps pkts 1.00 rx 85021 7363434 tx 85021 7363434 sock0@eth0:0 l2fwd xdp-skb pps pkts 1.00 rx 85003 7448446 tx 85003 7448446 sock0@eth0:0 l2fwd xdp-skb pps pkts 1.00 rx 84946 7533403 tx 84946 7533403 ==================================================== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -l -N -c sock0@eth0:0 l2fwd xdp-drv pps pkts 1.00 rx 132136 1092673 tx 132072 1092609 sock0@eth0:0 l2fwd xdp-drv pps pkts 1.00 rx 132428 1225118 tx 132428 1225054 sock0@eth0:0 l2fwd xdp-drv pps pkts 1.00 rx 132623 1357757 tx 132623 1357693 ==================================================== root@intel-corei7-64:~ $ ./xdpsock -i eth0 -l -z sock0@eth0:0 l2fwd xdp-drv pps pkts 1.00 rx 468476 43619530 tx 468476 43619466 sock0@eth0:0 l2fwd xdp-drv pps pkts 1.00 rx 468633 44088218 tx 468633 44088154 sock0@eth0:0 l2fwd xdp-drv pps pkts 1.00 rx 468439 44556775 tx 468439 44556711 ######################################################################## Based on the results obtained from above using xdpsock test cases, the result looks promising.
