Subject: [dpdk-dev] [PATCH] mk: change TLS model for ARMv8 and DPAA machine
Date: Tue, 5 Jun 2018 12:03:45 +0530 [thread overview]
Message-ID: <1528180425-27937-1-git-send-email-hemant.agrawal@nxp.com> (raw)
From: Sachin Saxena <sachin.saxena@nxp.com>
Random corruptions observed on ARM platfoms with using
the dpdk library in shared mode with VPP software (plugin).
sing traditional TLS scheme resolved the issue.
Tested with VPP with DPDK as a plugin.
