Subject: [dpdk-dev] [PATCH v2 0/7] add packed ring vectorized datapath
Date: Sat, 28 Mar 2020 00:54:05 +0800
Message-ID: <20200327165412.87359-1-yong.liu@intel.com> (raw)
In-Reply-To: <20200313174230.74661-1-yong.liu@intel.com>

This patch set introduced vectorized datapath for packed ring.

The size of packed ring descriptor is 16Bytes. Four batched descriptors
are just placed into one cacheline. AVX512 instructions can well handle
this kind of data. Packed ring TX datapath can fully transformed into
vectorized datapath. Rx datapath also can be vectorized when features
limiated(LRO and mergable disabled). User can specify whether disable
vectorized packed ring datapath by 'packed_vec' parameter of virtio user
vdev.

v2:
1. more function blocks replaced by vector instructions
2. clean virtio_net_hdr by vector instruction
3. allow header room size change
4. add 'packed_vec' option in virtio_user vdev 
5. fix build not check whether AVX512 enabled
6. doc update

Marvin Liu (7):
  net/virtio: add Rx free threshold setting
  net/virtio-user: add vectorized packed ring parameter
  net/virtio: add vectorized packed ring Rx function
  net/virtio: reuse packed ring xmit functions
  net/virtio: add vectorized packed ring Tx datapath
  net/virtio: add election for vectorized datapath
  doc: add packed vectorized datapath
