> Subject: [RFC] net/mlx4: add secondary process support
>
> In 19.05, mlx4 PMD will start to support secondary process. This will need
> new rdma-core API and small fix in kernel driver, in order for Verbs to allow
> using external (rte_malloc) memory allocator and remapping UAR space
> because secondary process has to access device queues and UAR for Tx
> doorbell. Majority of changes will come from mlx5 but mlx5_socket.c will not
> be imported. Instead, this will be replaced with the new rte_mp_*() APIs.
> This is for secondary process to acquire Verb's command file descriptor from
> primary process. The file descriptor is required to remap UAR.
>
> Patches are almost ready and I will be able to release v1 soon.
