Subject: [dpdk-dev] [PATCH v1 0/2] virtio: restrict pointer aliasing for loops vectorization
Date: Thu, 11 Jun 2020 11:32:46 +0800 [thread overview]
Message-ID: <20200611033248.39049-1-joyce.kong@arm.com> (raw)
This series is to optimize the virtio performance by using restrict
pointer aliasing, which allows the compiler to vectorize loops more
aggressively.
The patches were benchmarked by running PVP case on ThunderX2 platform
and showed positive performance results.
