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 hemant 412 Sep 16 18:38 tmp.api -rw-rw-r-- 1 hemant hemant 250 Sep 16 18:38 CMakeLists.txt Best wishes, Hemant From: Andrew 👽 Yourtchenko <[email protected]> Sent: Wednesday, September 16, 2020 4:12 PM To: [email protected] Cc: [email protected] Subject: Re: [vpp-dev] run existing plugin in VPP Hey Hemant, Welcome! :-) Most of the plugins load automatically (default), some don’t by default.. (see src/plugins/unittest/unittest.c on how it’s overridden). You can take a look at the config required to change the defaults in test/framework.py, line 422) Looking at those places, as well as the CDP plugin, should answer the question. (I am assuming you are a developer trying to get started with VPP so trying to give the pointers I myself would have found useful). --a On 16 Sep 2020, at 19:11, hemant via lists.fd.io <[email protected] <mailto:[email protected]> > wrote: Folks, I am new to VPP.
