Subject: [dpdk-stable] 17.11.10 fails to build from source on arm64
Date: Fri, 3 Jul 2020 06:37:16 +0200
Message-ID: <CAATJJ0LQBYg5ysPzg9pEPjj_0MCe5VeA+XfZAif2EaFpp4vfNA@mail.gmail.com> (raw)

Hi,
17.11.10 contains:
  [1] 4cd784b0 "net/mlx5: fix Rx CQ doorbell synchronization on aarch64"
Which is a backport from 94a24aaf

But if you build on arm64 with MLX5 enabled that breaks like:
  mlx5_rxtx_vec_neon.h:1035: undefined reference to `rte_cio_wmb'

I found and confirmed that adding the following on top of 17.11.10 fixes
the issue
  [2] 52bd60a5 "eal/arm64: define coherent I/O memory barriers"
