If the user requests to use an lcore above 128 using -l,

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.
There is no change in functionalty, just additional messages
suggesting how the --lcores option might be used for the supplied
list of lcores. For example, if "-l 12-16,130,132" is used, we
see the following additional output on the command line:
EAL: Error = One of the 7 cores provided exceeds RTE_MAX_LCORE (128)
EAL: Please use --lcores instead, e.g.
Minor suggestion: it would be good to clarify how to use lcores and what is
happening here in the example. Something like: "Please use --lcores
instead, to map lower lcore ids onto higher-numbered cores", could help the
user understand better what is happening.
Hi Bruce, how about:
EAL: Please use --lcores to map logical cores onto cores > RTE_LCORE_MAX
,e.g. --lcores 0@12,1@13,2@14,3@15,4@16,5@130,6@132
Rgds,
Dave.
--lcores 0@12,1@13,2@14,3@15,4@16,5@130,6@132
