Subject: [dpdk-dev] [PATCH] app/testpmd: Optimize membuf pool allocation
Date: Mon, 27 Aug 2018 17:33:18 +0800	[thread overview]
Message-ID: <1535362398-6526-1-git-send-email-phil.yang@arm.com> (raw)

By default, testpmd will create membuf pool for all NUMA nodes and
ignore EAL configuration.

Count the number of available NUMA according to EAL core mask or core
list configuration. Optimized by only creating membuf pool for those
nodes.

Fixes: d5aeab6542f ("app/testpmd: fix mempool creation by socket id")
