Added high/regular performance core pinning configuration options that can be used in place of the existing 'config' option. '--high-perf-cores CORELIST' option allow the user to specify a high performance cores list; if this option is not used and the 'perf-config' option is used, the application will query the system using the rte_power library in order to get a list of available high performance cores. The cores that are considered high performance are the cores that have turbo enabled. '--perf-config (port,queue,hi_perf,lcore_index)' option is similar to the existing config option, the cores are specified as indices for bins containing high or regular performance cores. Example: l3fwd-power -l 6,7 -- -p 0xff \ --high-perf-cores 6 --perf-config="(0,0,0,0),(1,0,1,0)" cores 6 and 7 are used, core 6 is specified as a high performance core. port 0 queue 0 will use a regular performance core, index 0 (core 7) port 1 queue 0 will use a high performance core, index 0 (core 6) Signed-off-by: Radu Nicolau <radu.nicolau@intel.com> Acked-by: David Hunt <david.hunt@intel.com>
