Public bug reported: == Comment: #0 - Hendrik Brueckner <[email protected]> - 2016-02-15 03:33:42 == Please include s390x support for the libmlx4 library. The s390 specific change is accepted upstream but not yet released in an libmlx4 version:
git://git.openfabrics.org/~yishaih/libmlx4.git commit f5c26f8762135f629c8cbe73d808e3029f07b176 Author: Alexey Ishchuk <[email protected]> Date: Wed Nov 19 11:17:19 2014 +0100 Add support for the s390x platform Since, s390x platform requires execution of privileged CPU instructions to work with PCI I/O memory, the PCI I/O memory cannot be directly accessed from the userspace programs via the mapped memory areas. The current implementation of the Inifiniband verbs uses mapped memory areas to write data to device UAR and Blueflame page to initiate the I/O operations, these verbs currently cannot be used on the s390x platfrom without modification. This patch contains the changes to the libmlx4 userspace Mellanox device driver library required to provide support for the DAPL API on the s390x platform. The original code that directly used mapped memory areas to access the PCI I/O memory of the Mellanox networking device is replaced with the new system call invocation for writing the data to mapped memory areas.
