New command line arguments are introduced to display stats for eventdev devices. The command example is like: For displaying a specific port stats (e.g. port 1): dpdk-proc-info -- --edev-stats-enable --edev-port=1 edev-stats-enable: This parameters enables proc-info to display xstats for eventdev devices. If the parameter is enabled through proc-info command line, proc-info will only dump event_dev data and exit. Users should not enable this flag if they desire to dump other proc-info data suc as Rx/Tx descriptor dump. More information can be found in proc-info app doc.
