Hi Damjan,
Thanks for the response and your suggestions.
Yes I too noticed that buffer clone API like vlib_buffer_copy() is missing.
Let me check if there is a way out to move to newer VPP in our project.
Shall get back if we have more questions.
Thanks,
Harish

That's pretty bad idea. Beside feature arcs, SPAN is also using buffer cloning
which is introduced post 16.06.
16.06 is very old release, not maintained, strongly suggest to move to new
version...

Hi,
I are currently using VPP 16.06 release.
We would like to enable SPAN feature (port mirroring) in 16.06, but it is
available only in VPP 17.01 release and above. It seems SPAN module depends
on vnet feature arc (vnet/feature/).
So my question is can we bypass vnet feature arc using some workar
As you’ve seen, ASSERTs are not compiled into production images. There are far
too many of them to simply change the macro in CLIB_DEBUG=0 images and expect
anything like acceptable performance.
I would guess it’s at least a 50% hit. A -g -O0 (TAG=vpp_debug) image is often
an order-of-magnitude
Hello. In our configuration process, it is not clear where the policer speed
limit is on the inbound flow rate or the output direction speed limit on the
interface. If it is in the direction, it would like to configure how the speed
limit of the output direction should be configured.

You can provide your own ASSERT mechanism in vppinfra/error_bootstrap.h
As is typical, we do not compile ASSERTs for non-debug builds. They add a
measurable overhead and peak forwarding performance will be impacted.

Since those are all Intel platforms and you propose building on an Intel
platform, just build and use it as-is. If you're not modifying anything just
use the packages we produce.
Most of the performance critical places that make use of CPU optimizations do
some magic to build more than one vers
Hi ,
For deployment , we want to replace assert with error log. Is there a way
in VPP to do that?
Thanks,
Chetan

1. make use of glic backtrace in execinfo.h. the old clib_backtrace is changed
to clib_backtrace_no_good
the old one is using __builtin_frame_address which can not retrieve stack
trace in release version (don’t know why)
2. install SIGABRT in signal h
Hi all,
I want to run vpp on those kinds of CPU, such as N2600 D525 2117U.
Is that possible? How can I do it if I build vpp on CPU I7?
Regards,
xlangyun
