Subject: [dpdk-dev] [PATCH v4 3/6] ip_pipeline: fix lcore mapping for varying SMT threads as in ppc64
Date: Sat, 6 Aug 2016 18:02:42 +0530 [thread overview]
Message-ID: <1470486765-2672-4-git-send-email-gowrishankar.m@linux.vnet.ibm.com> (raw)
In-Reply-To: <1470486765-2672-1-git-send-email-gowrishankar.m@linux.vnet.ibm.com>
From: gowrishankar <gowrishankar.m@linux.vnet.ibm.com>
offline lcore would still refer to original core id and this has to
be considered while creating cpu core mask.
