Change the forward topology while testpmd is running, the valid topologies are loop, paired, chained & custom.
When the forward topology is changed on the fly, all the ports will restore their active status. usage: testpmd> set fwd-topo paired|chained|loop|custom Signed-off-by: Wisam Jaddo <wis...@mellanox.com> --- app/test-pmd/cmdline.c | 42 +++++++++++++++++++++++++++++ app/test-pmd/config.c | 24 +++++++++++++++++ app/test-pmd/testpmd.h | 1 + doc/guides/testpmd_app_ug/testpmd_funcs.rst | 8 ++++++ 4 files changed, 75 insertions(+) diff --git a/app/test-pmd/cmdline.c b/app/test-pmd/cmdline.c index 9d48048..ecbecad 100644 --- a/app/test-pmd/cmdline.c +++ b/app/test-pmd/cmdline.c @@ -7651,6 +7651,47 @@ cmdline_parse_inst_t cmd_set_fwd_eth_peer = { NULL, }, }; +/* *** SET CUSTOM TOPO FOR CERTAIN PORT *** */ +struct cmd_set_fwd_topo_result { + cmdline_fixed_string_t set; + cmdline_fixed_string_t fwd_topo; + cmdline_fixed_string_t topo; +}; + +static void cmd_set_fwd_topo_parsed(void *parsed_result, + __attribute__((unused)) struct cmdline *cl, + __attribute__((unused)) void *data) +{ + struct cmd_set_fwd_topo_result *res = parsed_result; + + if (test_done == 0) { + printf("Please stop forwarding first\n"); + return; + } + if (!strcmp(res->fwd_topo, "fwd-topo")) { + set_set_fwd_topo(res->topo); + fwd_config_setup(); + } +} + +cmdline_parse_token_string_t cmd_set_fwd_topo_set = + TOKEN_STRING_INITIALIZER(struct cmd_set_fwd_topo_result, set, "set"); +cmdline_parse_token_string_t cmd_set_fwd_topo_fwd_topo = + TOKEN_STRING_INITIALIZER(struct cmd_set_fwd_topo_result, fwd_topo, "fwd-topo"); +cmdline_parse_token_string_t cmd_set_fwd_topo_topo = + TOKEN_STRING_INITIALIZER(struct cmd_set_fwd_topo_result, topo, NULL); + +cmdline_parse_inst_t cmd_set_fwd_topo = { + .f = cmd_set_fwd_topo_parsed, + .data = NULL, + .help_str = "set fwd-topo loop|paired|chained|custom", + .tokens = { + (void *)&cmd_set_fwd_topo_set, + (void *)&cmd_set_fwd_topo_fwd_topo, + (void *)&cmd_set_fwd_topo_topo, + NULL, + }, +}; /* *** SET CUSTOM TOPO FOR CERTAIN PORT *** */ struct cmd_custom_topo_result { @@ -16589,6 +16630,7 @@ cmdline_parse_ctx_t main_ctx[] = { (cmdline_parse_inst_t *)&cmd_mac_addr, (cmdline_parse_inst_t *)&cmd_set_fwd_eth_peer, (cmdline_parse_inst_t *)&cmd_set_custom_topo, + (cmdline_parse_inst_t *)&cmd_set_fwd_topo, (cmdline_parse_inst_t *)&cmd_set_qmap, (cmdline_parse_inst_t *)&cmd_set_xstats_hide_zero, (cmdline_parse_inst_t *)&cmd_operate_port, diff --git a/app/test-pmd/config.c b/app/test-pmd/config.c index 23799ad..cc403c6 100644 --- a/app/test-pmd/config.c +++ b/app/test-pmd/config.c @@ -2380,6 +2380,30 @@ set_fwd_eth_peer(portid_t port_id, char *peer_addr) new_peer_addr[c]; } +void +set_set_fwd_topo(char *topology) +{ + unsigned int portlist[RTE_MAX_ETHPORTS]; + unsigned int nb_pt = 0; + unsigned int i; + + if (!strcmp(topology, "custom")) + port_topology = PORT_TOPOLOGY_CUSTOM; + else if(!strcmp(topology, "loop")) + port_topology = PORT_TOPOLOGY_LOOP; + else if(!strcmp(topology, "chained")) + port_topology = PORT_TOPOLOGY_CHAINED; + else if(!strcmp(topology, "paired")) + port_topology = PORT_TOPOLOGY_PAIRED; + else { + printf("Please set valid forward topology\n"); + printf("valid topologies are: [custom, paired, loop & chained]\n"); + } + for (i = 0; i < RTE_MAX_ETHPORTS; i++) + portlist[nb_pt++] = i; + set_fwd_ports_list(portlist, nb_pt); +} + static void print_ports_range(void) { diff --git a/app/test-pmd/testpmd.h b/app/test-pmd/testpmd.h index 3250683..6b9db3b 100644 --- a/app/test-pmd/testpmd.h +++ b/app/test-pmd/testpmd.h @@ -605,6 +605,7 @@ int init_fwd_streams(void); void set_fwd_eth_peer(portid_t port_id, char *peer_addr); void set_custom_topo(portid_t port_id_1, portid_t port_id_2); +void set_set_fwd_topo(char *topology); void port_mtu_set(portid_t port_id, uint16_t mtu); void port_reg_bit_display(portid_t port_id, uint32_t reg_off, uint8_t bit_pos); void port_reg_bit_set(portid_t port_id, uint32_t reg_off, uint8_t bit_pos, diff --git a/doc/guides/testpmd_app_ug/testpmd_funcs.rst b/doc/guides/testpmd_app_ug/testpmd_funcs.rst index 5edf210..584ed6b 100644 --- a/doc/guides/testpmd_app_ug/testpmd_funcs.rst +++ b/doc/guides/testpmd_app_ug/testpmd_funcs.rst @@ -1098,6 +1098,14 @@ In custom topology the active ports will be the defiend in custum-topo only:: testpmd> set custom-topo (port_id_1) (port_id_2) +set fwd-topo +~~~~~~~~~~~~ +Set the forward topology on the fly. +Once the forward topology is changed on the fly, all ports will restore it's active +status:: + + testpmd> set fwd-topo loop|paired|chained|loop + set port-uta ~~~~~~~~~~~~ -- 2.7.4
