From mboxrd@z Thu Jan 1 00:00:00 1970 From: Jarod Wilson Subject: libmlx5 doesn't build on s390x Date: Thu, 23 Mar 2017 08:51:21 -0400 Message-ID: Mime-Version: 1.0 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-rdma-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org To: linux-rdma-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-Id: linux-rdma@vger.kernel.org Not sure if it's intentional, but in my adventure of the past day or two to get rdma-core v13 building across all the arches I need to build it for, I discovered that the mlx5 bits silently don't build on s390x. No build failure, they just aren't attempted, so far as I can see. The only sign of failure was when rpm %files globs failed to locate mlx5 bits. I noted that mlx4 has some s390x-specific trickery in providers/mlx4/mmio.h, and wondered if something similar was required for mlx5, or if "does not work on s390x and isn't expected to" is the norm. Currently, my builds are excluding mlx5 support on s390x due to the current state. -- Jarod Wilson jarod-H+wXaHxf7aLQT0dZR+AlfA@public.gmane.org -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
