Subject: [dpdk-dev] IPC/message passing between DPDK application and non-DPDK userspace application
Date: Fri, 17 Oct 2014 22:14:50 -0400 [thread overview]
Message-ID: <CAPrTskgxt69gEBA_duk0t+kb9uOKohpASo6gQQhBmhEBkDLR3w@mail.gmail.com> (raw)
Greetings,
I am still a DPDK newbie so not really sure how to go about doing this...
I have a DPI daemon running in userspace which uses libpcap for packet RX
that I would like to replace with DPDK ethernet PMD. However it is not
feasible to convert the entire application to run within the DPDK framework
which is why I would like to split packet RX to use DPDK and have my
applications higher order functions continue using Linux pthread.
Is it possible to exchange data between DPDK processes and regular
userspace processes via some shared mem or IPC mechanism? I am not sure if
the SW ring buffers that DPDK provides can be used in this context?
Please let me know if others have come across this. Any help from the DPDK
community would be greatly appreciated :)
