From e4785b0633574a607daaa04bf2fe43550055194f Mon Sep 17 00:00:00 2001 From: "Steven L. Roberts" Date: Wed, 10 May 2017 14:58:13 -0500 Subject: [PATCH] RDMA/hfi1: change PCI bar addr assignments to Linux API functions The Omni-Path adapter driver fails to load on the ppc64le platform due to invalid PCI setup. This patch makes the PCI configuration more robust and will fix 64 bit addressing for ppc64le.
