Subject: [dpdk-dev] [PATCH 0/2] Fix crash with vpmd and mbuf debug
Date: Fri,  3 Jul 2015 16:40:04 +0100	[thread overview]
Message-ID: <1435938006-22254-1-git-send-email-bruce.richardson@intel.com> (raw)

When mbuf debug support is turned on in the build time config, crashes will
occur when clearing up the RX/TX rings, if the 10G vector PMD is in use. This
error can be reproduced using testpmd.
This patchset makes the setup/teardown code easier to debug by marking "cold"
code paths as such, and then fixes the errors by checking for already-freed
mbufs when clearing the rings.

Bruce Richardson (2):
  ixgbe: add "cold" attribute to setup/teardown fns
  ixgbe: check mbuf refcnt when clearing RX/TX ring
