Hi Chris,
No plan for open sourcing yet. One reason is nobody is developing P4 programs for new VPP plugin nor is there any good online repo with great networking P4 programs. So, who would use the open-source compiler? The other reason is, I would like to complete the UPF VPP product first (VPP does need update checksum for layer-4). Open-sourcing takes time away time from our product development since we are only two people (I and Alex). Certainly, there is some VPP core code that has very simple CLI, no API, and there are plugins which has minimal CLI and maybe no API. With our compiler, every generated plugin has CLI and API support, so even existing plugins and core code would benefit. CLI details are included in the online demo slides. Sorry, I am not a public speaker, so please bear with the video demo. The tests do show running code including code running at scale. I think Intel or Cisco, who are larger companies, are better suited to open-source software. Both also have switching asics being programmed with P4 (Barefoot Tofino and CiscoONE) and both work with server products.

Resending. [If you didn’t read this recent short blog I wrote, https://mnkcg.com/need-for-a-p4tovpp-compiler/, this is what the first paragraph of the blog says. “VPP has stellar data plane code open-sourced by Cisco as a FD.io Linux project. Now VPP runs crypto on latest Intel server hardware at 1 Tbps. Most VPP new features are implemented as a plugin. VPP provides a script using Emacs Lisp to generate a plugin’s stub code. The generated code includes API and CLI to enable-disable plugin. MNK Labs & Consulting saw a need to generate a complete VPP plugin – this would cause less bugs with new plugin and also accelerate VPP plugin development. Emacs Lisp is not the right tool to generate a full VPP plugin including data plane code. MNK saw P4 as a good fit to describe any data plane and used P4 to generate a VPP plugin.” I have proved my point by generating a 5G UPF plugin using the compiler. ] Hemant -----Original Message----- From: vpp-dev@lists.fd.io <mailto:vpp-dev@lists.fd.io> <vpp-dev@lists.fd.io <mailto:vpp-dev@lists.fd.io> > On Behalf Of hemant via lists.fd.io Sent: Wednesday, May 05, 2021 10:47 AM To: vpp-dev@lists.fd.io <mailto:vpp-dev@lists.fd.io> Subject: [vpp-dev] VPP Emacs Lisp evolution to P4
