[vpp-dev] Regarding /var/run/.rte_config
Hi, I am running VPP with DPDK plugin. I see that when I normally run other non VPP DPDK applications, they create a file called /var/run/.rte_config But VPP running as a DPDK application (and calling rte_eal_init) does not create this file. There are consequences of the above in certain usecases where secondary processes try to look at this file. Can somebody advise why this file is not created when VPP is run with DPDK plugin. Or what needs to be done so that it does get created, or perhaps it is getting created somewhere that I am not aware of. I am running VPP as root.

Re: [vpp-dev] Regarding /var/run/.rte_config
Dear Prashant, We had lot of operational issues with dpdk leftover files in the past, so we took special care to made them disappear ASAP. Even if they are present you will not be able to use secondary process, we simply don't support that use case. Secondary process will not be able to access buffer memory as buffer memory is allocated by VPP and not by DPDK. Please note that VPP is not application built on top of DPDK, for us DPDK is just source of device drivers wit a bit of weight around them. Typical VPP feature code can work even without DPDK being present. If you explain your use case we might be able to advise you how to approach your problem in a way native to VPP, without relying on DPDK legacy features.

Re: [vpp-dev] Regarding /var/run/.rte_config
Hi Damjan, I was hoping to use the dpdk-pdump utility (built as part of DPDK) to generate the pcap files for traffic passing through the various ports. I have used that successfully with pure vanilla DPDK primary processes (non VPP usecases). It runs as a secondary process. Well, my requirement is to generate pcap's for ports on both tx and rx -- if you have an alternate VPP-core solution, that would be great.

Re: [vpp-dev] Regarding /var/run/.rte_config
Hi again Damjan, I am currently using VPP release 18.01 which just has the tx capture functionality. I see that VPP release 18.07 has introduced the rx capture functionality. At the moment, upgrading my release to 18.01 is not an option. Can you please advise how easy or difficult it will be to backport the rx capture functionality and add it as a patch to 18.01.

Please note that VPP is not application built on top of DPDK, for us DPDK is just source of device drivers wit a bit of weight around them. Typical VPP feature code can work even without DPDK being present. If you explain your use case we might be able to advise you how to approach your problem in a way native to VPP, without relying on DPDK legacy features.

I see that when I normally run other non VPP DPDK applications, they create a file called /var/run/.rte_config But VPP running as a DPDK application (and calling rte_eal_init) does not create this file. There are consequences of the above in certain usecases where secondary processes try to look at this file. Can somebody advise why this file is not created when VPP is run with DPDK plugin. Or what needs to be done so that it does get created, or perhaps it is getting created somewhere that I am not aware of. I am running VPP as root.
