Subject: [PATCH] kernel-boot: Do not perform device rename on OPA devices
|
|
|
e934f0 |
|
|
|
e934f0 |
PSM2 will not run with recent rdma-core releases. Several tools and
|
|
|
e934f0 |
libraries like PSM2, require the hfi1 name to be present.
|
|
|
e934f0 |
|
|
|
e934f0 |
Recent rdma-core releases added a new feature to rename kernel devices,
|
|
|
e934f0 |
but the default configuration will not work with hfi1 fabrics.
