Re: [vpp-dev] run existing plugin in VPP
Hi, All folks on this mailer are a VPP crew. So, even if I release a binary of the P4toVPP compiler, would anyone in VPP land even use the compiler? One would have to write P4 programs first. Not that writing a P4 program is rocket science – there is a Slack channel and mailer for P4 with very helpful crew. I don’t see an online repo of P4 programs just yet. VPP scripts generate a skeleton for a VPP plugin including API for plugin enable-disable. The compiler my company has developed generates CLI, API, and API handlers for plugin enable-disable and also for table entry add/delete/show tables. We are optimizing the compiler for better traffic performance as we speak. At least, if anyone uses the compiler, one doesn’t have to write CLI, API, and API handlers any more for a VPP plugin. Please let me know if anyone has any interest?

Yup, that would be very cool, because assuming the initial definition is correct and complete, then generating positive/negative tests should be possible mechanically. Since you know what at least the initial code structure is, you could make tests that hit every basic block at least in the initial code; and then some potentially based on the derived ranges of allowable values... (eg, if a feature is unicast, try feeding broadcast and see what happens, etc). If there are way too many tests then they can be moved to extended tests... Then one can more comfortably tweak the subsequent implementation of the node by hand to get more performance... Just one catch with the building the tests: there are three “timelines” in any of them: - time as seen by the python executor - time as seen by the VPP instance being driven - time as seen by the external observer At high concurrency they may become different things, so that might trip up the tests that assume they are all the same... —a > > Hemant > > From: vpp-dev@lists.fd.io On Behalf Of Andrew > Yourtchenko > Sent: Thursday, September 17, 2020 2:21 AM > To: hem...@mnkcg.com > Cc: vpp-dev@lists.fd.io > Subject: Re: [vpp-dev] run existing plugin in VPP > > Excellent! > > So would my guess be right that you plan to autogenerate the tests as well ? > > --a > > > On 17 Sep 2020, at 02:54, hem...@mnkcg.com wrote: > > > I did a “ps -ef | grep -I vpp” and found a few vpp processes (?) running.

Re: [vpp-dev] run existing plugin in VPP
I haven’t planned auto-generation of test_xxx.py yet. Looking at test_cdp.py, I see lot of python code which should be common to most plugin PTF tests. Thereafter, creating a good and bad packet for a protocol., enabling/disabling plugin should be straightforward to auto-generate. I think, I can generate tests_xxx.py and thereafter if a user wants, more tests or tweaks could be added.

What would be a good plugin to test performance with? That’s trickier... look around https://wiki.fd.io/view/CSIT - basically, perf testing the VPP is a separate project :-) but the good thing is some reports might be already there.. > > I love the fact that you (and perhaps others) have added lua examples to > vpp-api. Lua didn’t get much love for quite a while and I think would need some resuscitations to work :-) That said, last time I had a half a day to toy with it, in half a day I had something sorta working... but don’t expect what is in the tree to be up to date... it’s waiting for the folks to help it :-) > > I am developing a compiler which ingests P4 code and outputs a VPP plugin. > First, I will make the compiler functionally correct to support as many P4 > features and as many VPP features.

There is the lisp script somewhere in the tree that asks questions and spits out the plugin, but it’s a skeleton, with P4 one could probably go quite a good bit further...

Re: [vpp-dev] run existing plugin in VPP
Andrew, Thanks! Yes, I am a developer trying to get started with VPP. I run VPP using “make run-release” and get to the “vpp#” prompt. I could do a “cdp enable” and thus I know this plugin has been loaded. Now how to I run the packet testing in vpp/src/plugins/cdp/test/? There is a test_cdp.py in the path. I am familiar with PTF. Once I can run test.py for a plugin, I’d like to learn how to run performance testing to see how many packets/sec of a certain size I can achieve for a plugin. What would be a good plugin to test performance with? I love the fact that you (and perhaps others) have added lua examples to vpp-api. I am developing a compiler which ingests P4 code and outputs a VPP plugin. First, I will make the compiler functionally correct to support as many P4 features and as many VPP features. Then I will worry about performance which is a hard problem. If you see a VPP plugin, several files can be auto-generated by compiler or script. My compiler is already generating these files: -rw-rw-r-- 1 hemant hemant 1498 Sep 16 18:38 tmp_test.c -rw-rw-r-- 1 hemant hemant 10577 Sep 16 18:38 tmp.h -rw-rw-r-- 1 hemant hemant 79257 Sep 16 18:38 tmp.c -rw-rw-r-- 1 hemant hemant412 Sep 16 18:38 tmp.api -rw-rw-r-- 1 hemant hemant250 Sep 16 18:38 CMakeLists.txt Best wishes, Hemant From: Andrew Yourtchenko Sent: Wednesday, September 16, 2020 4:12 PM To: hem...@mnkcg.com Cc: vpp-dev@lists.fd.io Subject: Re: [vpp-dev] run existing plugin in VPP Hey Hemant, Welcome! :-) Most of the plugins load automatically (default), some don’t by default..

[vpp-dev] run existing plugin in VPP
Folks, I am new to VPP. I see several plugins in vpp/src/plugins. How do I run an existing plugin in VPP such as cdp?
