Hi Stephen,

Yes. The core mask we have aligned to separate cgroup. Probably this might be an issue here. We will change the alignment in our DPDK application.

BTW is there a way to check the cores affinity set to DPDK after rte_eail_init ? Do we have to use the taskset command ?

Please advise.

Thanks,

Kamaraj

Did you check that the core mask passed into the application is valid?
Or that that your application is not running in a container which blocks
access to other CPU's.
