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 --- app/test-pmd/config.c | 57 +++++++++++++++++++++++++++++- lib/librte_eal/common/eal_common_options.c | 45 ++++++++++------------- lib/librte_eal/common/include/rte_eal.h | 34 ------------------ lib/librte_eal/rte_eal_version.map | 1 - 4 files changed, 74 insertions(+), 63 deletions(-) diff --git a/app/test-pmd/config.c b/app/test-pmd/config.c index 49662cf..c10aa78 100644 --- a/app/test-pmd/config.c +++ b/app/test-pmd/config.c @@ -2587,6 +2587,61 @@ 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) { @@ -2601,7 +2656,7 @@ parse_fwd_portlist(const char *portlist) * requires a list of portids' so we use 2 arrays to do the * conversion between 2 formats. */ - if (eal_parse_optionlist(portlist, portindex, RTE_MAX_ETHPORTS) < 0) + if (parse_port_list(portlist, portindex, RTE_MAX_ETHPORTS) < 0) rte_exit(EXIT_FAILURE, "Invalid fwd port list\n"); RTE_ETH_FOREACH_DEV(idx) { diff --git a/lib/librte_eal/common/eal_common_options.c b/lib/librte_eal/common/eal_common_options.c index aa59f8b..5920233 100644 --- a/lib/librte_eal/common/eal_common_options.c +++ b/lib/librte_eal/common/eal_common_options.c @@ -571,36 +571,33 @@ eal_parse_service_corelist(const char *corelist) return 0; } -int -eal_parse_optionlist(const char *list, int *values, int maxsize) +static int +eal_parse_corelist(const char *corelist, int *cores) { unsigned 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; + for (idx = 0; idx < RTE_MAX_LCORE; idx++) + cores[idx] = -1; /* Remove all blank characters ahead */ - while (isblank(*list)) - list++; - - min = maxsize; + while (isblank(*corelist)) + corelist++; + /* Get list of cores */ + min = RTE_MAX_LCORE; do { - while (isblank(*list)) - list++; - if (*list == '\0') + while (isblank(*corelist)) + corelist++; + if (*corelist == '\0') return -1; errno = 0; - idx = strtol(list, &end, 10); + idx = strtol(corelist, &end, 10); if (errno || end == NULL) return -1; - if (idx < 0 || idx >= maxsize) + if (idx < 0 || idx >= RTE_MAX_LCORE) return -1; while (isblank(*end)) end++; @@ -608,18 +605,18 @@ eal_parse_optionlist(const char *list, int *values, int maxsize) min = idx; } else if ((*end == ',') || (*end == '\0')) { max = idx; - if (min == maxsize) + if (min == RTE_MAX_LCORE) min = idx; for (idx = min; idx <= max; idx++) { - if (values[idx] == -1) { - values[idx] = count; + if (cores[idx] == -1) { + cores[idx] = count; count++; } } - min = maxsize; + min = RTE_MAX_LCORE; } else return -1; - list = end + 1; + corelist = end + 1; } while (*end != '\0'); if (count == 0) @@ -627,12 +624,6 @@ eal_parse_optionlist(const char *list, int *values, int maxsize) return 0; } -static int -eal_parse_corelist(const char *corelist, int *cores) -{ - return eal_parse_optionlist(corelist, cores, RTE_MAX_LCORE); -} - /* Changes the lcore id of the master thread */ static int eal_parse_master_lcore(const char *arg) diff --git a/lib/librte_eal/common/include/rte_eal.h b/lib/librte_eal/common/include/rte_eal.h index 567b754..2f9ed29 100644 --- a/lib/librte_eal/common/include/rte_eal.h +++ b/lib/librte_eal/common/include/rte_eal.h @@ -71,40 +71,6 @@ enum rte_proc_type_t rte_eal_process_type(void); int rte_eal_iopl_init(void); /** - * Parse the user input - * - * This function can be used to read and parse the user input - * from the command line.
