If the user requests to use an lcore above 128 using -l, the eal will exit with "EAL: invalid core list syntax" and very little else useful information. This patch adds some extra information suggesting to use --lcores so that physical cores above RTE_MAX_LCORE (default 128) can be used. This is achieved by using the --lcores option by mapping the logical cores in the application to physical cores. For example, if "-l 12-16,130,132" is used, we see the following additional output on the command line: EAL: lcore 132 >= RTE_MAX_LCORE (128) EAL: lcore 133 >= RTE_MAX_LCORE (128) EAL: To use high physical core ids, please use --lcores to map them to lcore ids below RTE_MAX_LCORE, EAL: e.g. --lcores 0@12,1@13,2@14,3@15,4@16,5@132,6@133 The same is added to -c option parsing. For example, if "-c 0x300000000000000000000000000000000" is used, we see the following additional output on the command line: EAL: lcore 128 >= RTE_MAX_LCORE (128) EAL: lcore 129 >= RTE_MAX_LCORE (128) EAL: To use high physical core ids, please use --lcores to map them to lcore ids below RTE_MAX_LCORE, EAL: e.g. --lcores 0@128,1@129 Signed-off-by: David Hunt <david.hunt@intel.com> Acked-by: Bruce Richardson <bruce.richardson@intel.com>
