Can you share the output of testpmd 'show port info all'? See 
https://doc.dpdk.org/guides/testpmd_app_ug/testpmd_funcs.html#show-port

Hi Benoit,

Yes, testpmd works perfectly well.

I've uploaded the coredump here (

Version:                  v20.01-release

Compiler:                 GCC 7.3.1 20180303 (Red Hat 7.3.1-5)

Command line arguments:
./build-root/install-vpp_debug-native/vpp/bin/vpp

Are there any venues I might explore that might be causing the issue?

2020-05-11 Thread Benoit Ganne (bganne) via lists.fd.io 
Hi Mohammed, it really looks like a DPDK issue. Could you share the coredump? 
See 
https://fd.io/docs/vpp/master/troubleshooting/reportingissues/reportingissues.html#core-files

Also, does your interface work with DPDK testpmd, including 'show port info 
all'.

Re: [vpp-dev] Chelsio CXGBE crash on startup #dpdk

2020-05-11 Thread Benoit Ganne (bganne) via lists.fd.io 
Hi Mohammed, the crash is happening in DPDK when trying to get link status.

> Also tested with v19.08.2 and v18.10

I suppose it means the trace below uses master?

Also, could you try again building DPDK in debug mode (note: you'll need to 
remove any vpp-ext-deps package 1st)?
~# make rebuild DPDK_DEBUG=y

Thanks  Mrityunjay,

CXGBE_PMD is enabled by default in VPP dpdk build, the PMD is built and the 
interfaces are detected, however, as you can see from the backtrace is dies 
when trying to link_update? (I assume)

I guess, If you are lucky, then below patch will work for you.  Hope
your firmware version >= 1.17.14.0.
