Subject: [dpdk-dev] [PATCH] crypto/virtio: alloc private data by NUMA affinity
Date: Wed, 4 Sep 2019 21:21:51 +0800 [thread overview]
Message-ID: <20190904132151.58885-1-xiao.w.wang@intel.com> (raw)
It's better to allocate device private data on the same NUMA node with
device, rather than with the main thread. This helps avoid cross-NUMA
access for worker thread.
