Thank Antonin! I was aware off the first two; the vmware one was the rumor I was chasing.

I should also have mentioned the vmware ebpf project, p4c-xdp: https://github.com/vmware/p4c-xdp<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fvmware%2Fp4c-xdp&data=02%7C01%7CCSommers%40ixiacom.com%7C29db474a8a2544edc92408d4b5050437%7C069fd614e3f843728e18cd06724a9b23%7C0%7C0%7C636332480528856809&sdata=A%2Bx2u5u7zcPQSk5m1yqZlYWdFkHcMiHDTFcJgbUlxjg%3D&reserved=0>
This project offers more features that the ebpf backend on p4lang.

Hi Chris,

I am aware of 2 projects that might qualify, but I am not sure if either of them can be considered of production quality at this stage:
- PISCES, a P4-programmable version of OVS: http://pisces.cs.princeton.edu/<https://na01.safelinks.protection.outlook.com/?url=http%3A%2F%2Fpisces.cs.princeton.edu%2F&data=02%7C01%7CCSommers%40ixiacom.com%7C29db474a8a2544edc92408d4b5050437%7C069fd614e3f843728e18cd06724a9b23%7C0%7C0%7C636332480528856809&sdata=jQM9KDc7lNAohGluv2iOZQocKs7UcJ0p6tvnwzK6mNk%3D&reserved=0>
- P4 at ELTE, a project which generates C code which interfaces with DPDK: https://github.com/P4ELTE/t4p4s<https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2FP4ELTE%2Ft4p4s&data=02%7C01%7CCSommers%40ixiacom.com%7C29db474a8a2544edc92408d4b5050437%7C069fd614e3f843728e18cd06724a9b23%7C0%7C0%7C636332480528856809&sdata=OArWn8L9YV%2FlKjI3QY8H%2FiQu5YkzYWcfS8Rc6dCqZso%3D&reserved=0>
I would recommend that you get in touch with the developers for these projects.

Thanks,

Antonin

Hi All,
I was wondering if anybody knows of an x86 target for P4 which might be forthcoming? Something which runs at “production” packet rates, suitable for deployment in a VNF or docker container, etc.? This could be either a more complete eBPF target or something else. Thanks.
