        "content": "Here are some comments about the use case of this patch:\n\nThis patch is especially useful in cases where DPDK applications scale \ntheir CPU resources at runtime via starting and stopping slave lcores. \nSince the coremask defines the maximum scale-out for such a application, \nthe master lcore becomes to the minimum scale-in.\nImagine, running multiple primary processed of such DPDK applications, \nusers might want to overlap the coremasks for scaling. However, it would \nstill make sense to run the master lcores on different CPU cores.\n\nIn DPDK vSwitch we might end up in such a scenario with a future release:\n   https://lists.01.org/pipermail/dpdk-ovs/2014-March/000770.html\n   https://lists.01.org/pipermail/dpdk-ovs/2014-March/000773.html\n\nThanks,\n\nSimon\n\nOn 08.07.2014 10:28, Simon Kuenzer wrote:\n> This commit enables users to specify the lcore id that\n> is used as master lcore.\n>\n> Signed-off-by: Simon Kuenzer <simon.kuenzer@neclab.eu>\n> ---\n>   lib/librte_eal/linuxapp/eal/eal.c |   33 +++++++++++++++++++++++++++++++++\n>   1 file changed, 33 insertions(+)\n>\n> diff --git a/lib/librte_eal/linuxapp/eal/eal.c b/lib/librte_eal/linuxapp/eal/eal.c\n> index 573fd06..4ad5b9b 100644\n> --- a/lib/librte_eal/linuxapp/eal/eal.c\n> +++ b/lib/librte_eal/linuxapp/eal/eal.c\n> @@ -101,6 +101,7 @@\n>   #define OPT_XEN_DOM0    \"xen-dom0\"\n>   #define OPT_CREATE_UIO_DEV \"create-uio-dev\"\n>   #define OPT_VFIO_INTR    \"vfio-intr\"\n> +#define OPT_MASTER_LCORE \"master-lcore\"\n>\n>   #define RTE_EAL_BLACKLIST_SIZE\t0x100\n>\n> @@ -336,6 +337,7 @@ eal_usage(const char *prgname)\n>   \t       \"[--proc-type primary|secondary|auto] \\n\\n\"\n>   \t       \"EAL options:\\n\"\n>   \t       \"  -c COREMASK  : A hexadecimal bitmask of cores to run on\\n\"\n> +\t       \"  --\"OPT_MASTER_LCORE\" ID: Core ID that is used as master\\n\"\n>   \t       \"  -n NUM       : Number of memory channels\\n\"\n>   \t\t   \"  -v           : Display version information on startup\\n\"\n>   \t       \"  -d LIB.so    : add driver (can be used multiple times)\\n\"\n> @@ -468,6 +470,21 @@ eal_parse_coremask(const char *coremask)\n>   \treturn 0;\n>   }\n>\n> +/* Changes the lcore id of the master thread */\n> +static int\n> +eal_parse_master_lcore(const char *arg)\n> +{\n> +\tstruct rte_config *cfg = rte_eal_get_configuration();\n> +\tint master_lcore = atoi(arg);\n> +\n> +\tif (!(master_lcore >= 0 && master_lcore < RTE_MAX_LCORE))\n> +\t\treturn -1;\n> +\tif (cfg->lcore_role[master_lcore] != ROLE_RTE)\n> +\t\treturn -1;\n> +\tcfg->master_lcore = master_lcore;\n> +\treturn 0;\n> +}\n> +\n>   static int\n>   eal_parse_syslog(const char *facility)\n>   {\n> @@ -653,6 +670,7 @@ eal_parse_args(int argc, char **argv)\n>   \t\t{OPT_HUGE_DIR, 1, 0, 0},\n>   \t\t{OPT_NO_SHCONF, 0, 0, 0},\n>   \t\t{OPT_PROC_TYPE, 1, 0, 0},\n> +\t\t{OPT_MASTER_LCORE, 1, 0, 0},\n>   \t\t{OPT_FILE_PREFIX, 1, 0, 0},\n>   \t\t{OPT_SOCKET_MEM, 1, 0, 0},\n>   \t\t{OPT_PCI_WHITELIST, 1, 0, 0},\n> @@ -802,6 +820,21 @@ eal_parse_args(int argc, char **argv)\n>   \t\t\telse if (!strcmp(lgopts[option_index].name, OPT_PROC_TYPE)) {\n>   \t\t\t\tinternal_config.process_type = eal_parse_proc_type(optarg);\n>   \t\t\t}\n> +\t\t\telse if (!strcmp(lgopts[option_index].name, OPT_MASTER_LCORE)) {\n> +\t\t\t\tif (!coremask_ok) {\n> +\t\t\t\t\tRTE_LOG(ERR, EAL, \"please specify the master \"\n> +\t\t\t\t\t\t\t\"lcore id after specifying \"\n> +\t\t\t\t\t\t\t\"the coremask\\n\");\n> +\t\t\t\t\teal_usage(prgname);\n> +\t\t\t\t\treturn -1;\n> +\t\t\t\t}\n> +\t\t\t\tif (eal_parse_master_lcore(optarg) < 0) {\n> +\t\t\t\t\tRTE_LOG(ERR, EAL, \"invalid parameter for --\"\n> +\t\t\t\t\t\t\tOPT_MASTER_LCORE \"\\n\");\n> +\t\t\t\t\teal_usage(prgname);\n> +\t\t\t\t\treturn -1;\n> +\t\t\t\t}\n> +\t\t\t}\n>   \t\t\telse if (!strcmp(lgopts[option_index].name, OPT_FILE_PREFIX)) {\n>   \t\t\t\tinternal_config.hugefile_prefix = optarg;\n>   \t\t\t}\n>",

It might be better to remove the cfg->master_lcore setting from eal_parse_coremask(), and defer the selection of the master lcore until all of the command-line options have been parsed.  If —master-lcore was specified, save the value and use that, otherwise rte_get_next_lcore(-1, 0, 0) can return the first bit set in the coremask.\n\n-Aaron",
