Support for NETMAP framework, to support other Oses that Linux.

[tatuzemdp]

Hi there, any change to allow netmap to be used for high speed access to NIC rings?

I already considered netmap as an good option which should also allow higher PPS compared to packet_mmap. Plan would be to support multiple IO modes like packet_mmap (default), netmap or DPDK.

Which OS is interesting for you besides Linux (FreeBSD, Windows, ...)?

Hi there! For now just interested on FreeBSD...

If you want i can help, not really good at coding but at least some donation.

You can try initial draft with netmap support here: https://github.com/rtbrick/bngblaster/tree/netmap

cd build
cmake -DBNGBLASTER_NETMAP=on -DBNGBLASTER_VERSION=netmap ..

Feedback welcome!

To enable netmap, the following needs to be added in config.

{
    "interfaces": {
        "tx-interval": 1, 
        "rx-interval": 1,
        "io-mode": "netmap",
        "network": {
            "interface": "veth2",
            "address": "100.0.0.10",
            "gateway": "100.0.0.2"
        }
    }
}

The rx/tx interval is 5ms per default but you can lower the poll rate to 1ms to reach higher PPS values.

Dear, Chris, hope you are doing fine.

I clone and tried to compile but having issues with libdict. going out now but will try to sort it later.

Basically libdict seems to be broken, hence removed from FreeBSD 6 months ago (lucky me).

I will keep you posted.

You can build/install libdict manually from here:

https://github.com/rtbrick/libdict

Will do! Thanks for the pointer!On 20 Mar 2021 13:07, Christian Giese @.***> wrote: You can build/install libdict manually from here: https://github.com/rtbrick/libdict

Hi Chris,

SO, libdict is now compile/installed and out of the way.

As expected, is complaining about linux/if_packet.h (just commented out to see where else it complain) and got issues with CIRCLEQ that is not part of sys/queue.h.

I will continue on later on, keep you posted.

Chris, will be it be enough to replace circularq with a STAILQ?  -------- Original message --------From: Christian Giese @.> Date: 20/03/2021 13:07 (GMT+01:00) To: rtbrick/bngblaster @.> Cc: Santiago Martinez @.>, Author @.> Subject: Re: [rtbrick/bngblaster] Support for NETMAP framework, to support other Oses that Linux.

The BNG Blaster will officially support Linux only.
