How to use cryptodev ?

[gary]

Hi all,

   I'm trying to port the interface of crypto module to my app ,  there is two program running on the same server.both use DPDK version is 19.11
  
    for the first time, I use rte_eal_init in my app. Run my program first and then another program , and this time my program exits . 
    So I made another try , since the other programs on the same server had already configured the dpdk environment settings,  there was no rte_eal_init called. compile app with dpdk is ok ,  but when the process execution ,I got the following err,how can be solved?  Thanks!


Core usage=   3   4   4   4   4   4   5   5   5   4   4   4   4   4   4   5   5   5   TotalCoreUsage=  77
