Running DPDK without root permisions

[hezyabudy]

I have C application that using DPDK. today i am running the application with root permissions.

I would like to run my application without the root permissions. currently I have problems with rte_eal_init function. i got this error: EAL: FATAL: Cannot use IOVA as 'PA' since physical addresses are not available EAL: Cannot use IOVA as 'PA' since physical addresses are not available

my OS is 14.04, kernel 4.4.0-36-generic i noticed that at DPDK docs there is a remark about "Running DPDK Applications Without Root Privileges", but i wonder if someone has experience?

https://doc.dpdk.org/guides/linux_gsg/enable_func.html#running-dpdk-applications-without-root-privileges

also, alternative i can lunch the DPDK ports from another application that has root privileges. at my application i will just consume the packet, is it possible?

thanks
