Subject: app/testpmd: disable memory locking on FreeBSD
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=fb7b8b32cd958f03d3e327b4cd046cf0c815d3b3;p=dpdk.git

app/testpmd: disable memory locking on FreeBSD

If mlockall() is called while allocated VA space is bigger than
amount of available RAM, FreeBSD kernel will deadlock and need
a hard reboot. We do allocate big amounts of memory because of
how new memory subsystem works, so calling mlockall() will cause
a deadlock. So, disable mlockall() by default on FreeBSD.
