[dpdk-dev] Regarding mbuf allocation/free in secondary process

[Saravana Kumar <maheshmcc39@gmail.com>]

Hi DPDK community,



I'd like to have DPDK NIC IO operations in (primary) process and
execution logic in (secondary) processes.
Primary process pushes NIC Rx mbufs to Secondary process through S/W ring

Seconary process allocates mbuf for Tx path and pushes down to Primary
process for NIC Tx


I have few doubts here:

1. If Secondary process dies because of SIGKILL then how can the mbufs
allocated in Secondary process can be freed.
   If it is normal signals like SIGINT/SIGTERM then we can be catch
those and free in those respective signal handlers

2. Secondary process needs to poll on the S/W ring. This can consume 100% cpu.
   Is there a way to avoid polling in secondary process for Rx path

Thanks

Sara
