Hi all,
I would like to know if it's possible to run my DPDK application (I'm using
DPDK 19.11) under Valgrind.
I tried but it gets stuck apparently while accessing hugepages:
----

I've seen there was some attempt a few years ago:
http://mails.dpdk.org/archives/dev/2016-February/033108.html
has anything changed since that?
Also I see that Luca has created a project here
https://github.com/bluca/valgrind-dpdk
but seems like there were no changes since 3 years... I wonder if that works or
not with recent DPDK versions...
Thanks for any hint,
Francesco Montorsi
