With portmask, we can use only upto 64 ports. This portlist option enables the user to use more than 64 ports. Now we can specify the ports in 2 different ways - Using portmask (-p [0x]nnn): mask must be in hex format - Using portlist in the following format --portlist [-p2][,p3[-p4],...] --portmask 0x2 is same as --portlist 1 --portmask 0x3 is same as --portlist 0-1 Signed-off-by: Hariprasad Govindharajan --- v3: squashed the 2 patches and made it 1 patch with changes only in testpmd. Also working on optmizing the parser v2: moved the parser function to testpmd --- app/test-pmd/config.c | 80 +++++++++++++++++++++++++++++++++++++++++++++++ app/test-pmd/parameters.c | 5 +++ app/test-pmd/testpmd.h | 3 ++ 3 files changed, 88 insertions(+) diff --git a/app/test-pmd/config.c b/app/test-pmd/config.c index 9669cbd..c10aa78 100644 --- a/app/test-pmd/config.c +++ b/app/test-pmd/config.c @@ -2587,6 +2587,86 @@ set_fwd_ports_list(unsigned int *portlist, unsigned int nb_pt) } } +static int parse_port_list(const char *list, int *values, int maxsize) +{ + unsigned int count = 0; + char *end = NULL; + int min, max; + int idx; + + if (list == NULL || values == NULL || maxsize < 0) + return -1; + + for (idx = 0; idx < maxsize; idx++) + values[idx] = -1; + + /* Remove all blank characters ahead */ + while (isblank(*list)) + list++; + + min = maxsize; + + do { + while (isblank(*list)) + list++; + if (*list == '\0') + return -1; + errno = 0; + idx = strtol(list, &end, 10); + if (errno || end == NULL) + return -1; + if (idx < 0 || idx >= maxsize) + return -1; + while (isblank(*end)) + end++; + if (*end == '-') { + min = idx; + } else if ((*end == ',') || (*end == '\0')) { + max = idx; + if (min == maxsize) + min = idx; + for (idx = min; idx <= max; idx++) { + if (values[idx] == -1) { + values[idx] = count; + count++; + } + } + min = maxsize; + } else + return -1; + list = end + 1; + } while (*end != '\0'); + + if (count == 0) + return -1; + return 0; +} + +void +parse_fwd_portlist(const char *portlist) +{ + unsigned int portcount = 0; + int portindex[RTE_MAX_ETHPORTS]; + unsigned int ports[RTE_MAX_ETHPORTS]; + unsigned int idx; + /* + * eal_parse_portlist() will mark the portindex array + * with -1 if the port is not listed and with a positive value + * for the listed ports. however, the function set_fwd_ports_list() + * requires a list of portids' so we use 2 arrays to do the + * conversion between 2 formats. + */ + if (parse_port_list(portlist, portindex, RTE_MAX_ETHPORTS) < 0) + rte_exit(EXIT_FAILURE, "Invalid fwd port list\n"); + + RTE_ETH_FOREACH_DEV(idx) { + if (portindex[idx] != -1) + ports[portcount++] = idx; + } + + set_fwd_ports_list(ports, portcount); +} + void set_fwd_ports_mask(uint64_t portmask) { diff --git a/app/test-pmd/parameters.c b/app/test-pmd/parameters.c index 6340104..404dba2 100644 --- a/app/test-pmd/parameters.c +++ b/app/test-pmd/parameters.c @@ -57,6 +57,7 @@ usage(char* progname) "[--help|-h] | [--auto-start|-a] | [" "--tx-first | --stats-period=PERIOD | " "--coremask=COREMASK --portmask=PORTMASK --numa " + "--portlist=PORTLIST " "--mbuf-size= | --total-num-mbufs= | " "--nb-cores= | --nb-ports= | " #ifdef RTE_LIBRTE_CMDLINE @@ -92,6 +93,7 @@ usage(char* progname) "packet forwarding.\n"); printf(" --portmask=PORTMASK: hexadecimal bitmask of ports used " "by the packet forwarding test.\n"); + printf(" --portlist=PORTLIST: list of forwarding ports\n"); printf(" --numa: enable NUMA-aware allocation of RX/TX rings and of " "RX memory buffers (mbufs).\n"); printf(" --port-numa-config=(port,socket)[,(port,socket)]: " @@ -587,6 +589,7 @@ launch_args_parse(int argc, char** argv) { "nb-ports", 1, 0, 0 }, { "coremask", 1, 0, 0 }, { "portmask", 1, 0, 0 }, + { "portlist", 1, 0, 0 }, { "numa", 0, 0, 0 }, { "no-numa", 0, 0, 0 }, { "mp-anon", 0, 0, 0 }, @@ -825,6 +828,8 @@ launch_args_parse(int argc, char** argv) parse_fwd_coremask(optarg); if (!strcmp(lgopts[opt_idx].name, "portmask")) parse_fwd_portmask(optarg); + if (!strcmp(lgopts[opt_idx].name, "portlist")) + parse_fwd_portlist(optarg); if (!strcmp(lgopts[opt_idx].name, "no-numa")) numa_support = 0; if (!strcmp(lgopts[opt_idx].name, "numa")) diff --git a/app/test-pmd/testpmd.h b/app/test-pmd/testpmd.h index 3dd5fc7..33ef3e2 100644 --- a/app/test-pmd/testpmd.h +++ b/app/test-pmd/testpmd.h @@ -614,6 +614,9 @@ lcore_num(void) rte_panic("lcore_id of current thread not found in fwd_lcores_cpuids\n"); } +void +parse_fwd_portlist(const char *port); + static inline struct fwd_lcore * current_fwd_lcore(void) {
