[dpdk-dev] [PATCH RFC v1 0/6] barrier fix and optimization for mlx5 on aarch64

[Gavin Hu]

Using just sufficient barriers really matters to performance.
Insufficient barriers will cause issues while barriers stronger
than required, especially in the fast path is a performance killer.

In the joint preliminary testing between Arm and Ampere, 8%~13%
performance was measured.

Gavin Hu (5):
  net/mlx5: relax the barrier for UAR write
  net/mlx5: use cio barrier before the BF WQE
  net/mlx5: add missing barrier
  net/mlx5: add descriptive comment for a barrier
  net/mlx5: non-cacheable mapping defaulted for aarch64

Phil Yang (1):
  net/mlx5: relaxed ordering for multi-packet RQ buffer refcnt
