Subject: [dpdk-dev] [PATCH v2 0/6] Restrict pointer aliasing with a common wrapper
Date: Mon,  6 Jul 2020 15:49:24 +0800	[thread overview]
Message-ID: <20200706074930.54299-1-joyce.kong@arm.com> (raw)
In-Reply-To: <20200611033248.39049-1-joyce.kong@arm.com>

As the 'restrict' keyword is recognized in C99, this patchset is to
add a wrapper defining '__rte_restrict' which can be supported by
all compilers. Then replace the existing 'restrict' and '__restrict'
in different vpmds, and optimize vhost/virtio with restricted pointer
aliasing for more aggressive loops vectorization.

The vhost/virtio optimization patches were benchmarked by running PVP
case on ThunderX2 platform and showed positive performance results.

Joyce Kong (6):
  lib/eal: add a wrapper to define restricted pointers
  net/virtio: restrict pointer aliasing for NEON vpmd
  lib/vhost: restrict pointer aliasing for packed vpmd
  net/i40e: replace restrict with rte restrict
  examples/performance-thread: replace restrict with wrapper
  net/mlx5: replace restrict keyword with rte restrict
